Teachers’ perceptions of staff collaboration at South African inviting schools: a case study Prof GM Steyn Department of Educational Leadership and Management University of South Africa, P O Box 392, Pretoria, 0003, South Africa. As rated researcher, the research has been supported by the National Research Foundation in South Africa Abstract This study reports on staff members’ perceptions of teacher collaboration at two South African schools that received the inviting school award from the International Alliance for Invitational Education. The inviting school survey assesses the invitational qualities based on the four assumptions of the Invitational Education theory. Although these assumptions are harmoniously related, this article primarily focuses on the second assumption: that education is a collaborative cooperative activity. A quantitative research design was deemed most appropriate for this study. The five dimensions of Hord’s model were used to determine staff’s perceptions of collaborations at these schools; (1) shared leadership; (2) a shared vision and values; (3) individual and shared learning; (4) shared practice; and (5) supportive conditions. The results revealed that the five dimensions of Hord’s model were evident at both these schools, which confirmed the existence of teacher collaboration at these schools. The significant contribution of this study lies in the verification and validation of invitational education in Hord’s model. Keywords: Invitational education; teacher collaboration; Hord’s model; professional learning communities 1. Introduction In the last two decades there has been extensive research on the importance of teacher collaboration for the sake of quality education; and teacher collaboration as an essential requirement for school improvement through its constructive impact on teachers’ learning and practice and the performance of students (Brouwer, 2011:7; Ertesvåg, 2011:1; Goddard & Britton, 2011:5; Goddard, Goddard & Tschannen-Moran, 2008:878; Lockhorst, Van der Pol & Admiraal, 2008:253; Nehring & Fitzsimons, 2011:516). However, numerous studies indicate that the sphere of influence of teachers is confined to their classroom walls, and limited opportunities are provided for collaboration (Brouwer, 2010:7; Darling-Hammond, Wei, Andree, Richardson, & Orphanos, 2009:57; Ertesvåg, 2011:1; Printy, 2010: 125; Sigurðardóttir, 2010:407). Therefore, to meet the needs and challenges of students, solo-practice needs to be replaced by a collaborative system where teachers frequently engage in in-depth dialogue (Fulton & Britton, 2011:5). Moreover, recent school reforms have focussed on teacher collaboration as a tool for improving the quality of schools (Brouwer, 2011:21; McLauglin &Talbert, 2010:35; Lockhorst et al., 2008:253), even in South Africa (Republic of South Africa, 2011:13). Professional learning communities, through teacher collaboration, are currently viewed as a framework to enhance teacher collaboration, a shared vision, reflective dialogue and applied learning in order to improve student performance (Blacklock, 2009:10; Nelson, Deuel, Slavit, Kennedy, 2010: 175). This has stimulated scholars to continue their exploration into the role of professional learning within school contexts (Williams, 2010:3). Although a number of studies described the design of professional learning communities, and more studies on professional learning communities, as a means for teachers’ continuing professional growth, are required (Brouwer, 2011:9; Katz & Earl, 2010:27,28). Moreover, the Department of Education (2011:82) in South Africa recommended the development of guidelines to establish and develop professional learning communities for schools. Such studies on professional learning communities are necessary to inform educational policies and contribute towards steering the professional learning community phenomenon (Christianakis, 2010:110). The researcher was instrumental in assisting the two schools in the study to obtain the prestigious inviting school award from the International Alliance for Invitational Education. She also gained insight into these two schools from previous studies. Invitational Education considers collaboration and collectivity among role players as one of the crucial assumptions to ensure an inviting school environment. This study which is also part of a research project attempted to gain an understanding of how the staff at these schools perceived the existence of professional learning communities at their schools. 2. Conceptual framework Various models that describe and define professional learning communities and teacher collaboration have been developed (Chappuis, Chappuis & Stiggins, 2009; Katz & Earl, 2010.; Hord, 1997; Hord, 2004). The following models are highlighted for the purpose of this study: The four basic assumptions of Invitational Education; Mitchell and Sackney’s model of capacity building for a learning community (2001); and Hord’s Professional Learning Community model (1997). Invitational Education is viewed as an ethical theory of practice that centres around a set of consistent assumptions about human behaviour and thinking (Shaw, Siegel & Schoen, line n.d.:5). This approach attempts to authentically create and sustain a welcoming school environment that is intentionally founded on respect, trust, optimism and care for the sake of increased learning outcomes; and the personal growth of all role players (Shaw et al, n.d.:5). Although the primary focus of this study is on the second assumption of the four basic assumptions of Invitational Education that are harmoniously related (Shaw et al, n.d.: 5; Purkey & Siegel, 2003:7-24): 1. People are able, valuable and responsible and should be treated accordingly. 2. Helping others is a collaborative, cooperative association in which the process is as important as the product. 3. People have relatively untapped capacities in all aspects of individual development. 4. Individual capacities can be best achieved by the 4 Ps (places, policies and programmes) that are intentionally developed to enhance individual growth, and by people who continue to realise their capacities in themselves and others, both personally and professionally. The third lens for interpreting this study was Mitchell and Sackney’s model (2001) of capacity building for a learning community. This model focuses on building three essential capacities, namely personal, interpersonal and organisational capacities. From a school perspective, personal capacity refers to a combination of embedded values, beliefs; and knowledge and skills that teachers possess; and the skilled networks by means of which they interact. In order to build interpersonal capacity, the emphasis moves from the individual to a group with mutual relationships and collaborative practice at its centre. Since new methods and shared values take time to develop, it can be expected that collaboration will develop through different phases that are characterised in team development (Mitchell & Sackney, 2001). Moreover, a particular kind of communication is required to form a collaborative team that encourages the development of shared understandings and engagement in collective inquiry to create new objectives for professional operations at a school (Mitchell & Sackney, 2001). The third capacity of Mitchell and Sackney’s model (2001) refers to building organisational capacity that begins with the awareness that structural arrangements could inhibit collaboration or could remove isolation between teachers. It means that a professional learning community at a school requires a unique kind of organisational structure that could have an impact on personal and interpersonal capacity building. For Mitchell and Sackney (2001) the first walls to be broken down from an organisational structure point of view are those negative attitudes that exist in the minds of individuals. It is also necessary to provide structural opportunities for professionals to interact. Once sufficient trust has developed among staff members, it may enhance constructive dialogue and reduce or remove conditions that negatively influence professional learning in teams. Leadership is also shared among staff members where individuals undertake leadership roles at the school. The third model on which the study on teachers’ collaborative learning was based is Hord’s Professional Learning Community model (1997). Professional learning community models aim at designing structures that reduce or remove the isolation of teachers and enhance collective learning among them to attain shared objectives for student learning (Piccardi, 2005: 6; Williams, 2010:139). Hord’s model (1997) identifies the following five dimensions of a professional learning community which are also supported by various other scholars: Dimension 1: Supportive and shared leadership: Changing a school into a learning community requires the leadership of principals to create a school environment for the continuous collective learning of teachers. (Fulton & Britton, 2011:14; Hord, 1997:2; Hord, 2007:8; Cranston, 2009:2; Hargreaves, 2007:187; Katz & Earl, 2010:27; Stoll, Bolam, Mcmahon, Wallace & Thomas, 2006:235; Richardson, 2009:29; Williams, 2010:4). Dimension 2: Shared values and vision: Sharing a vision is considered to be a mental picture of what is essential to both individuals and the school (Hord, 2007:8; Greer, 2012:8; Katz & Earl, 2010:27). It is necessary that teachers are committed and willing to focus strongly on the primary goal of improving their teaching practice for the sake of improved student learning (Fulton & Britton, 2011:14; Greer, 2012: 8). According to Fulton and Britton (2011:14), this dimension is the most critical factor for effective teacher collaboration. Dimension 3: Individual and collective learning: In a professional learning community teachers work and learn collectively by sharing their professional skills and knowledge and by applying innovative teaching methods to ensure effective student learning (Blacklock, 2009: 135; Katz & Earl, 2010:27). Dimension 3: Dimension 4: Shared personal practice: To develop a shared practice, teachers need to observe and visit one another’s classrooms regularly to discuss observations constructively (Hord, 1997:4; Greer, 2012: 8). Mutual trust and respect are also basic elements for an effective learning community in the shared practice of staff (Cranston, 2009:10; Fulton & Britton, 2011:7). Dimension 5: Supportive conditions: Hord (2007:10) distinguishes between two factors of supportive conditions, namely structural and physical factors and human capabilities. Structural and physical arrangements include aspects such as appropriate scheduled time to meet; access to resources and structures to improve communication; and reduce isolation among teachers (Chenoweth, 2009:41; Fulton & Britton, 2011:14; Greer, 2012:8; Katz & Earl, 2010:28; Williams, 2010:18). Building trust requires ample time for teachers to develop mutual norms and language for the team to operate (Fulton & Britton, 2011:15; Hord, 1997:4; Katz & Earl, 2010:28). 3. The school contexts The researcher was instrumental in assisting the two schools to become inviting schools. Both these schools received the prestigious award from the International Alliance for Invitational Education; School A in 1993 and School B in 2010. The nomination for the inviting school award in 1993 entailed the completion of an Inviting School Survey by all role players which focusing on the existence of the socalled four Ps (people, places, policies, and programmes) in invitational education. The ISS survey which was a product of WW Purkey, the co-founder of Invitational Education, was originally a 100-item Likerttype, hand-scored instrument without psychometrics, such as reliability and validity indices and norms to support the instrument (Smith, 2012). Since then applications for the inviting school award were revised and School B had to complete the Inviting School Survey-revised (ISS-R) and submit a portfolio that attended to five dimensions: people, places, policies, programmes and processes (Shaw et al., n.d: 15; Smith, 2012; Steyn, 2013: 560). The ISS-R is a 50-item Likert-type five-point survey that was completed by students, teachers and parents at the school (Shaw et al., n.d: 15). In 2010 a new principal took over at School A which led to an even stronger focus on teacher learning and academic performance of students and School B intentionally started to adhere to the assumptions of invitational education after its nomination as an inviting school in 2009. The study particularly focused on the second assumption: Education is a collaborative, cooperative activity. Schools A and School B were urban schools located in the eastern and southern suburb respectively in Gauteng, South Africa. School A had approximately 1750 students and School B approximately 1790 students. The socioeconomic environments of these schools ranged from average to above average although a number of students are exempted from school fees. The school visions of both schools focussed on current and future directed student learning through quality teaching. At School A the professional learning structure became prominent in the second year of the appointment of a new principal who placed huge emphasis on teacher collaboration and who also played a key role in creating a learning community at the school (Steyn, 2014a; Steyn, 2014b). School A reduced the number of students in the Grade 5 to 7 Mathematics classes to 15 students per class and school B appointed 16 class assistants for Grade 4 to 7 classes in the main subjects– Mathematics, Afrikaans and English to help with discipline, marking papers and the identification of learning problems in these classes. The school profile of both schools showed stability and homogeneity of the teachers and students. Of the 95 staff members at School A, 40 teachers were departmental and 55 governing body appointments, while School B had 66 staff members of which 41 were departmental and 25 governing body appointments. 4. Research design The two inviting schools of the study were purposefully selected since previous studies revealed collaborative learning cultures at these schools (Steyn, 2013a; Steyn, 2013b; Steyn, 2013c; Steyn, 2014a: in press; Steyn, 2014b: In press). For the purpose of this study a quantitative research design, particularly a descriptive case study, was chosen to explore the perceptions of staff members with regard the existence of teacher collaborative practices at their schools. Hord’s (1996) “School professional staff as a learning community questionnaire” which was most appropriate to answer the research question, was administered. It was designed to assess the development and maturity of teacher collaboration in a professional learning community (Meehan, Orletsky & Sattes, 1997:iv). The items were based on the staff’s perceptions of the existence of teacher collaboration in a professional learning community at the schools. The survey comprised 17 items; and the staff members at both schools were invited to complete it. According to Meehan and others (1997:4) there are five major dimensions of a professional learning community: (1) the involvement and facilitation of the principal who shares leadership, power and decision-making with his staff members (with two descriptors); (2) a shared vision and values which show staff members’ dedication to student learning which is continuously communicated and put into operation in the work of staff members (with three descriptors); (3) teachers’ collaborative learning during which solutions are developed to attend to the needs of students (with five descriptors); (4) the analysis and inquiry into teachers’ classroom practices by colleagues with a view to assist and provide feedback for individual and school improvement (with two descriptors); and (5) Supportive conditions which comprise physical circumstances and human capabilities that promote staff’s collaborative operations (with five descriptors). Each of these dimensions with its sub-items consists of descriptors on a Likert response scale of 5 (strongly agree and high) to 1 (strongly disagree and low). Higher scores show a more positive and confirmed view of a specific dimension in the collaborative practices of a school as a learning community (Gaspar, 2010:26.) The data from the Hord’s study showed that the School Professional Staff as a Learning Community (SPSaLC) instrument revealed suitable reliability and validity measures that were applicable to similar studies (Meehan et al 1997:29, 33). According to Meehan and others (1997:45) the concurrent validity of Hord’s instrument “does possess satisfactory correlation with the school climate instrument used in this field test”. Cronbach’s Alpha that determined the reliability of the total instrument revealed a score of 0.9389 (Meehan et al., 1997:29). The content, concurrent and construct validity were also studied and considered to be acceptable (Meehan et al., 1997:36-38). In order to ensure content validity of this instrument, three different stages were used. After an extensive literature review Hord constructed the five dimensions in the first stage which consisted of 17 descriptors and 51 indicators (Meehan et al., 1997:36). Three Appalachia Educational Laboratory (AEL) staff members completed the content validity assessment in the second stage to reformat Hord’s instrument which had been used in the pilot test of an AEL project (Meehan et al., 1997:36). Another check on the content was done in the third stage when staff of the AEL gave their reformatted instrument to the initial designer (Meehan et al., 1997:36). The researcher applied for and received ethical approval from two bodies; The Gauteng Department of Education and the University of South Africa to conduct the study. Moreover, the Southwest Educational Development Laboratory (SDEL) gave written permission to use Hord’s (1997) questionnaire for this study. Both principals also agreed to continue studies at their schools. Staff completed the survey anonymously and the participation of staff in the study was voluntary. At School A, a total of 52 questionnaires out of 95 were returned at the end of 2013 which represents a return rate of 54.73%. Considering the fact that only 40 staff members were permanent, departmental appointments and the rest governing body appointments, it could be considered as a relatively high return rate. At School B a total of 41 questionnaires out of 66 were returned which represents a return rate of 67%. As in the case of School B, the return rate was relatively high considering that 41 posts were departmental appointments and the rest (25) governing body appointments. This study’s investigation, therefore, totalled the number of questionnaires ( 93) at the two schools for the purpose of this study. For the purpose of this study the internal consistency of scale responses of both schools was assessed by Cronbach’s Alpha, since the study focussed on how collaboration manifested in two inviting South African schools. The overall Cronbach Alpha coefficients were 0.75 for supportive and shared leadership; 0.78 for developing shared values and a vision; 0.83 for collective learning and application; 0.81 for shared personal practice; and 0.83 for supportive school conditions at both schools. The data analysis for this study was done by means of SAS JMP (version) 10.0. A limitation of this exploratory study was that it employed a quantitative design that measured frequencies of dimensions and not the quality of collaboration or types of collaboration that existed in these two schools. 5. Findings The descriptive study used in this study investigated the status of the five dimensions of Hord’s Learning Community Model (1996) at two inviting primary schools in South Africa. The data collected from the study revealed that staff rated themselves above average as a professional learning community at these two schools as explained below. Dimension 1: Supportive and shared leadership of Hord’s survey, attempted to determine whether the principals involved teachers to share power, authority and decision-making (Hord 1996:1). Table 1. Supportive and shared leadership Dimension 1: Supportive and shared leadership Subdimensions of the statement 2 % of Total 3 % of Total 4 % of Total 5 % of Total 4.30% 19.35% 43.01% 33.33% 1.11% 34.44% 36.67% 27.78% 1a: The principal consistently involves staff in decision-making at the school. 1b The principal involves the entire staff in the decision-making process. Mean Standard deviation 3.99 0.74 It is revealed in table 1 that 76.34% of staff agreed that the principals consistently involved staff in decision-making at the schools; while 64.45% of staff members believed that the principals involved the entire staff in the decision-making process. No 'strongly disagree' responses were recorded and only 4.3% and 1.11% respectively disagreed with the statements in 1a and 1b at both schools. Although both principals were democratic in the decision-making process, the large number of staff at both schools made it difficult to involve the entire staff. For both these subdimensions the mean of 3.99 was relatively high while the standard deviation of 0.74 was relatively small. Dimension 2: The shared values and vision measured the shared visions for school improvement that had an undeviating focus on student learning, and were consistently referenced for the staff's work (Hord, 1996:1). Table 2. Shared vision and values Dimension 2: Shared vision and values Subdimensions of the statement 2a Staff share visions of school improvement. 1 2 % of Total 1.10% 3 4 5 % of Total % of Total % of Total % of Total 1.10% 19.78% 39.56% 38.46% Dimension 2: Shared vision and values Subdimensions of the statement 1 % of Total 2b Visions of improvement focussed on students, teaching and learning 2c Visions of improvement with 0.00% quality learning for all students as target Mean 4.42 2 3 4 5 % of Total % of Total % of Total % of Total 1.09% 0.00% 3.23% 3.26% 8.60% 29.35% 22.58% 66.30% 65.59% Standard deviation 0.64 It is revealed in table, that 2 78.02% of staff agreed that they had a shared vision of school improvement; 95.65% of staff concurred that the visions of improvement focused on students, teaching and learning; while 88.17% believed that these visions targeted quality learning for all students. The high percentages in this dimension showed that staff had a well-defined vision, which focused on improving teaching and learning to ensure quality learning for all students. Compared to dimension 1, this dimension showed an even higher mean (4.42) and lower standard deviation (0.64) which revealed staff member’s experience of a shared vision and values. Dimension 3: Collective learning and its application of learning: assessed staff members’ co-operative learning and whether applying such learning led to high intellectual learning responsibility and answers to the needs of students (Hord, 1996:2). Table 3: Collective learning and its application of learning Dimension 3: Collective learning and its application of learning Subdimensions of the statement 2 3 4 5 % of Total % of Total % of Total % of Total 3a The entire staff meets to discuss issues, share information and learn from one another. 2.15% 30.11% 33.33% 34.41% 3b Staff meets regularly to discuss substantive studentcentred issues. 0.00% 13.33% 35.56% 51.11% 3c The staff discuss the quality of their teaching and students’ learning. 1.09% 13.04% 36.96% 48.91% 3d The staff, based on the learning, make and implement plans to address student’s needs, more effective teaching and more successful learning. 1.09% 7.61% 41.30% 50.00% 3e Staff assesses and debrief the impact of their actions and make revisions. 2.17% 7.61% 46.74% 43.48% Mean Standard deviation 4.28 0.58 It is revealed in item 3a in table 3 that less staff members (67.74%) than in others subdimensions of Dimension3 concurred that the entire staff meets to discuss issues, share information and learn from one. This is in line with the response in 1b (64.45%) where the entire staff was involved in decision-making. The relatively large number of teachers (95 at School A and 93 at School B) did not allow for constructive dialogue. However, according to the data, collective learning occurred in teams since 86.67% of staff concurred that they convened regularly to discuss student-centered educational issues; 85.87% of staff members agreed that they debated the quality of their teaching and student’s learning; 81.30% of staff indicated that, based on learning in teams, they made and implemented plans to attend to the needs of students, more effective teaching and more successful learning; while 90.22% of staff was of the opinion that they assessed and debriefed the impact of their actions and made the necessary revisions. With regard to subdimensions, 3b to 3e, teachers experienced constructive dialogue in teams and that they implemented those decisions taken during interactions for the sake of more successful teaching and learning. In line with dimension 2, this attribute showed a relatively high mean of 4.28 and a relatively low standard deviation of 0.58. Dimension 4: The shared practice of staff: Measured whether staff members observed and reviewed one another’s classroom practices and provided feedback accordingly to enhance individual and school capacity (Hord, 1996:2,3). Table 4. Shared practice Dimension 4: Shared practice Subdimensions of the statement 1 2 3 4 5 % of Total % of Total % of Total % of Total % of Total 4a Staff regularly visit and observe one another’s teaching. 4.30% 11.83% 31.18% 38.71% 13.98% 4b Staff members provide feedback to one another about teaching and learning based on their observations. 3.26% 4.35% 17.39% 42.39% 32.61% Mean Standard deviation 3.72 0.92 It is revealed in table 4 that only 52.69% of staff agreed that they often visited and observed one another’s classrooms. This was also the lowest score compared to the other dimensions of the professional learning community model. However, a higher score of 75.10% indicated that teachers provided feedback after such events. The mean of 3.72 was also lower than those of the other dimensions while the standard deviation (0.92) was higher. The compulsory peer observation in the Integrated Quality Management System and the performance management system in South African schools allowed for such shared practices to occur annually. However, the workload of teachers and full time table made the scheduling of extra opportunities for staff to observe and visit one another’s classroom practices very difficult. Dimension 5: Supportive conditions: Attempted to measure the conditions and capacities that supported the school's arrangement as professional learning organisations (Hord, 1996:3). Table 5. Supportive conditions Dimension 5: Supportive conditions Subdimensions of the statement 2 % of Total 3 % of Total 4 % of Total 5 % of Total 5a Time is arranged for whole staff interactions. 2.25% 4.49% 55.06% 38.20% 5b The size, structure and arrangements of the school 2.20% 14.29% 54.95% 28.57% Dimension 5: Supportive conditions Subdimensions of the statement 2 % of Total 3 % of Total 4 % of Total 5 % of Total 5c A variety of processes and procedures are used to encourage staff communication. 1.10% 6.59% 45.05% 47.25% 5d Trust and openness characterise all of the staff members. 5.49% 25.27% 36.26% 32.97% 5e All staff members have caring, collaborative and productive relationships 0.00% 13.19% 58.24% 28.57% facilitate staff proximity and interaction. Mean Standard deviation 4.17 0.56 It is revealed in table 5 that 93.26% of respondents agreed that the schools schedule time for staff interactions; 83.52% of staff members were of the opinion that although their schools are large, the size, structure and arrangements of large schools nevertheless allowed for staff proximity and interaction; a score of 92.30% showed that a variety of processes and procedures existed to encourage staff communication; 79.23% of staff members perceived trust and openness among staff members, while 86.81% experienced caring, collaborative and productive relationships at their schools. The various high positive responses in the sub-dimensions showed that the schools provided supportive environments for professional learning communities to function effectively. The mean of 4.17 is in line with dimensions 1, 2 and 3 while the standard deviation is the lowest of all the other attributes. The total score of the mean and standard deviation of these five dimensions were 4.02 and 0.51 respectively. This score indicates the extent to which staff members were of the opinion that the schools created a positive learning environment and that they were supportive as learning communities. The higher the total mean score, the more positively the school was viewed as a professional learning community. 6. Discussion This study attempted to investigate two primary inviting schools and examine staff members’ views on the status of professional learning communities at their schools according to the Professional Learning Community model developed by Hord (1997a). This study found that the two inviting schools exhibited characteristics of each of the five dimensions of Hord’s model. The results of this study reveal the existence of supportive and shared leadership. According to Hord (2004:8) the transformation of a school into a professional learning community requires the endorsement of school leaders’ endorsement and enthusiastic nurturing of the professional development of their staff as a learning community. The data indicated that although the entire staff was less involved in decisionmaking, both these schools provided other opportunities to consistently involve staff in decision-making at the schools. Stoll and others (2006:243-246) state that school contexts such as the size of the school may have an impact on the effectiveness of professional learning communities. However, theoretical models on professional learning communities confirm the necessity of both shared and supportive leadership for the successful operation of such communities (Blacklock, 2010:312; Gaspare, 2010:4; Terry, 2013:65). Principals play a crucial role in developing professional learning communities by sharing leadership and supporting collaborative learning (Cranston, 2009:16; Greer, 2012:30; Higgins, 2010:65; Reimer, 2010:16; Williams, 2010:4). However, to commence the drive for teacher collaboration in their schools, it is necessary that principals raise a sense of urgency among staff members to work and learn collectively in order to enhance their own learning and that of their students (Williams, 2010:153; Greer, 2012: 30). It also means that they need to help staff understand the functioning of collaborative teams at the school (Chappuis et al., 2009:57). Moreover, it implies that principals should not be solely responsible for leading instructional reform in schools and they need to capitalise on the expertise of staff and build on teacher leadership for the sake of creating effective professional learning communities at their schools (McLaughlin & Talbert, 2007:157). Furthermore, it also necessitates leadership to find shared ‘pictures of a future with staff members that could foster genuine commitment (Senge, 1990: 8; Williams, 2010:22). Fulton and Britton (2010:37) are of the opinion that the second dimension of Hord’s model (1996), sharing a vision and values, is the first key factor for a successful learning community at schools. The results of this study reveal the existence of shared values and a collectively developed vision that promotes improvement at both schools. The collected data, therefore, support the identified dimension: shared values and a vision in ‘n professional learning community (Greer, 2012:88). This also confirms the results in similar studies (Blacklock, 2010: 312; Huffman & Hipp, 2003:43; Reimer, 2010:17). By implication, the second assumption of invitational education, education is a collaborative, cooperative activity, was also supported by the findings of the study. The schools also shared the responsibility of student learning and growth (Nehring & Fitzsimons, 2011:515). Principals lead their teachers to work and learn collaboratively with a common vision of a professional learning community where students are viewed as “academically capable and staff envision learning environments to support and realize each student’s potential achievement” (Hord, 2004:8). It is within a learning community that a collective understanding of successful student learning emerges and also what staff members would like to achieve in future (Fleming, 2007:24; Fulton & Britton, 2010:47; Richardson, 2009: 25). Moreover, the shared vision then serves as a context for decisions on teaching practices, collaborative learning efforts of teachers and student learning at a school (The Centre for Comprehensive School Reform and Improvement 2009:1). The results of this study, however contradict the results of Higgins’study (2010). Higgins (2010:106; 107) shows that staff did not agree or discuss the vision of the school and they lost focus of the goals at the school. Sharing knowledge and skills support both individual and collective learning at schools (Drago-Severson 2007:99). The notion of building personal and interpersonal capacities in Mitchell and Sackney’s model (2001) was also confirmed by the findings of this study. Moreover, the major focus of shared personal practice is on teachers’ professional learning where they learn and work together by continually assessing their teaching practices and the needs of their students (The Centre for Comprehensive School Reform and Improvement 2009:1). Williams (2010:104) is of the opinion that a known advantage of teacher collaboration lies in the notion of “pooled intelligence”. He believes that the “concept is founded on the premise that collaboration prompts all participants to share their expertise, thus increasing the knowledge and skill of all members of the group” (Williams, 2010:104). The dimension “shared personal practice” in this study was reported with the lowest mean score of 3.72. This finding was also supported by a study of Blacklock (2010: 336). Moreover, compared to other sub-dimensions in this study, staff reported the lowest score for opportunities to visit and observe other teachers regularly. The Integrated Quality Management System in South Africa is an attempt by the Department of Education to monitor and evaluate the performance of teachers with a view to improving the quality of education at schools. In this system teachers are appraised once or twice a year by a panel of appraisers who conduct class visits with a view to obtaining assessment scores for performance measurement purposes. In a study of Rabichund and Steyn (2014:353) teachers suggested that IQMS be aborted and that class visits be conducted throughout the year to have an impact on the professional development of teachers. The notion of regular classroom visits during which teachers discuss classroom observations and debated teaching practices was also supported by studies done by Maistry (2008:131), Reimer (2010:18,19) and Williams (2010:125). Sharing classroom practices assist in building a cohesiveness among team members which enhances the professional learning of teachers. (Greer, 2012: 8). The results of the study also show the existence of collective learning and its application of learning. Professional learning in communities at both these schools were demonstrated by staff working and learning collectively and collaboratively together (Hord, 2004:9) thereby supporting the second assumption of invitational education. These results were also corroborated by other studies (Blacklock, 2010: 344; Drago-Severson, 2007:87; Greer, 2012:88; James, Dunning, Connolly & Elliott, 2007:548; Reimer, 2010:18,19). However, as in the instance of dimension 1: shared leadership; respondents also indicated that professional learning among the entire staff in subdimension 3a occurred less than in other subdimensions. The fact that both schools were relatively large in size explains their responses (Stoll et al., 2006:243-246). In order to meet the learning needs of students, the historically solo-practices of teachers need to change to collaborative practices whereby teachers continuously engage in teams to develop their knowledge and skills (Darling-Hammond, Wei, Andree, Richardson, & Orphanos, S 2009: 2; Ertesvåg, 2011:1; Fulton & Britton, 2011:5; Nehring & Fitzsimons, 2011:526). Staff who intentionally focus on learning attempt to search for and create the necessary support activities and opportunities to move beyond the current status quo (Katz & Earl, 2010:32). Moreover, within professional learning communities a culture of learning is valued, supported and encouraged by all staff members (Blacklock, 2010: 345). The results of this study are contradicted by Higgins (2010:107) which indicated that staff did not apply learning experiences from interactions with other teachers and they also did not value the importance of such interactions. In line with this view McLaughlin and Talbert (2007:160) state that staff from different departments often think that they have little in common to share. An appropriate, supportive learning environment where staff at schools can collaborate as a unit to learn, make decisions, solve problems and work creatively is required (Fulton & Britton, 2011:14; Hord, 2004: 10; Hord, 2007:11). Blacklock (2010: 319) states that organisational structures at schools which provide supportive conditions play an essential and integral role to ensure the effectiveness of professional learning communities. Staff members in this study reported that their school schedule and organisation allowed staff to collaborate effectively. These findings, therefore, support the building of organisational capacities as identified by Mitchell and Sackney’s model (2001) and also the fourth assumption of invitational education: that individual capacities in the school’s organisation are intentionally developed to promote individual development, personally and professionally. Although both schools are large they nevertheless succeeded in providing a variety of processes and procedures to encourage staff communication. The supporting conditions for effective professional learning communities also require caring, collaborative and productive relationships which include trust and openness among staff members (Cranston, 2009:10; Fulton & Britton, 2011:7; Katz & Earl, 2010:29, 30). In this regard Hargreaves (2007:187), Higgins (2010:109) and Fleming (2007:28) maintain that developing trust is critical for sustaining professional learning communities. The data, therefore, supports the identified characteristic of this dimension in the professional learning community. The findings of this study are also supported by those of Greer (2012: 89), James, and others (2007:548) and Blacklock (2009: 183). 7. Conclusion With the teaching profession’s emphasis on communities of learners, schools need to implement collaborative models of professional development. The findings of this study suggest the existence of the five professional learning community dimensions of collective learning of Hord’s model at two South African inviting schools. Learning more about the collaborative culture of these successful schools and studying them through the theoretical framework of the Professional Learning Community model, elaborated on the practices which promoted the success of these schools. The collaboration model at these schools revealed a well-developed structure for the professional collaboration which all staff members understood and respected. The following implications can be drawn from this study: Strong leadership capacities in communicating and sharing the vision for building and maintaining professional learning communities at schools are required. As instructional leaders, the principals need to be committed to teachers’ professional learning by sharing school leadership at the schools. It implies that principals should acknowledge the expertise of staff members and ensure their active participation in the functioning of the school. Staff requires a strong understanding of the purpose of collaboration which implies the necessity to share values and a vision that is focussed on improved teaching practices for the sake of improved student learning. Collective learning occurs when individual teachers work together in collaborative relationships to develop professionally and enhance student learning. The teachers need to develop the necessary skills and processes to collaborate effectively for the sake of improving their individual learning and that of their students. Shared practice requires the building of trust and respect among staff members and also commitment and willingness to share their practices. By implication it means to abandon competition among staff members and to break down any barriers that are created by isolation at schools. Supportive, conducive conditions are required at schools for professional learning communities to function effectively. This implies the institution of structural and physical conditions to ensure teacher collaboration. The necessary time for teachers to meet regularly on a sustained basis with a hectic school time table remains a challenge for schools. Moreover, such regular scheduled opportunities are required since it takes time to build teacher qualities, such as care, trust, and respect to ensure effective collegial, collaborative relationships. The findings of this study might help policymakers to design appropriate professional development programmes that focus on teacher collaboration. However, a limitation of the study is that it focussed on a single case study: professional learning communities at two South African inviting schools. Based on the findings of this study; and considering the fact that school contexts differ, the following studies are recommended: (1 A study that compares the views of staff in the two inviting schools to show similarities and differences in the professional learning communities at the schools. (2) A study at inviting schools in other countries on how the dimensions of Professional Learning Communities in Hord’s model (1996) are revealed (3) A study on how the factors in different school contexts influence the development and existence of professional learning communities at schools may contribute to the current body of knowledge in transforming schools into professional learning communities.
