th nd Joint International IGIP-SEFI Annual Conference 2010, 19 - 22 September 2010, Trnava, Slovakia COMPETENCE ORIENTED TEACHER TRAINING Sigrun Eichhorn and Manuela Niethammer Dresden University of Technology, 01062 Dresden, Faculty of Education sigrun.eichhorn@tu-dresden.de; manuela.niethammer@tu-dresden.de Abstract: Newcomers reflect and evaluate lessons by judging outside characteristics, such as time management, visible patterns of action (for example the reading of a text, the copying of a panel), or the like (episodic representations). Thus, only the phenomenological aspect of teaching and learning is accessible to them. Experts analyse, evaluate, and devise lessons by engaging the inner, psychological processes of teaching and learning. Foremost those are the correlations between the instructions given by the teacher and the cognitive achievement they initiate in the learner, for example interpreting, comparing, abstracting, and arranging facts and connections. Experts characterise the process of teaching and learning as an aimcontent-method relation that cannot be separated (categorical and hypothetical representations). Studies show that the development of competencies from the stage of a newcomer to that of an expert cannot be achieved merely by conveying knowledge of experts and professionals in a theoretical framework. It is more often the case that students in teacher training have a hard time seeing correlations between the professional, academic knowledge taught and their preconceptions of teaching. They are more likely to use teaching methods and scripts which they experienced themselves for years [1]. This means that they never get past the stage of episodic representation. In teacher training, the main objective is to abolish the reproduction of those didactic patterns and to replace them by a theory-based development of competencies. To do so, the following questions need to be considered: What levels of didactic competence can be detected and identified by which indicators? What barriers between the individual levels have to be overcome and which basic approaches can initiate and promote such actions? The first precondition for developing a competence-oriented teacher training is that newcomers to teaching will acquire first-hand teaching experience. Based on these experiences episodic representations can be formulated which can then be connected with professional knowledge and motivate the further development to categorical and hypothetical representations. Keywords: teacher training, teaching competence, teaching concepts 1. Initial Situation Studies show barriers in teacher trainees competence development in the field ―teaching.― th nd Joint International IGIP-SEFI Annual Conference 2010, 19 - 22 September 2010, Trnava, Slovakia By contrast to experts, beginners often have difficulties to establish connections between taught professional knowledge and their own teaching concept. They mainly capture teaching by means of superficial characteristics such as time management or noticeable action patterns (= episodic representations). On the other hand, experts analyse lessons with regard to the psychological structure of teaching and learning processes. They succeed in doing so due to their knowledge of correlations between teaching activity and the thereby initiated cognitive activities of the learners (professional knowledge). This knowledge quality is the basis for efficient and appropriate teacher activities according to the situation [2]. It is characterised by linking episodic, categorical and hypothetical teaching representations which can hardly be established by solely theoretical knowledge imparting. The development of such knowledge structures requires working with specific teaching situations. Correspondingly, the integration of teacher trainings (cf [3]; [4]) as well as the use of approaches to ―situated learning― [5], [6] [7]1 are recommended for the teacher education. Still, (video-based) teaching reflection as a method for teacher training is rarely found in Germany [8] 2. On the one hand, reasons for it are social and individually psychologically barriers which impede a critical and constructive observation or evaluation of their own lesson [9]. On the other hand, the current state of research concerning the effectiveness of video-based teacher education is still dissatisfactory [10], [11]. 2. Research Topics For the implementation of teaching reflection as a competence oriented teacher education method, the following subproblems are to be clarified: overcoming social and individually psychologically barriers3 for a critical and constructive observation or evaluation of their own lessons [9], the design of the concept has to follow the logic sequence of the development levels, i.e. a selection and preparation of teaching situations in connection with suitable observation, reflection and optimisation tasks following the teacher trainees‘ learning conditions because the high complexity and dynamics of real teaching are mostly hard to determine, especially by newcomers empirical testing of the approach effectiveness 3. Competence Oriented Approach for Didactic Education 3.1 Developing Indicators for the Competence Development Based on a Model for the Description of Teaching Competence Development (Expert-NoviceApproach) Models for the description of the competence development are nothing new. The theories on competence development by Havighurst [12] as well as Dreyfus and Dreyfus [13], which base on a logic sequence of the development levels are important and have already been taken up by technical and vocational education and training research since the late 1980s. The starting point is that experts are distinguished from novices regarding the knowledge development of area specific deep structure (domain knowledge) [1], [14], [15]. Experts characterise a professional problem situation predominantly by their nature on a high-level of abstraction. However, novices mainly notice details, th nd Joint International IGIP-SEFI Annual Conference 2010, 19 - 22 September 2010, Trnava, Slovakia superficial characteristics [16]. Respectively, domain knowledge of experts and novices differs in terms of quality of the domain specific knowledge structures. This provides starting points for the description of professional competence levels. The quality of these knowledge structures is linked to the type of internal organisation and elaboration of this knowledge. Categories, cognitive schemes and mental models are fundamental cognitive units for internal organisation and elaboration of knowledge. Based on these cognitive units, the acting person can realize that a given situation shows similarities with experienced situations in the past (analogies), so that they can benefit from existing knowledge about objects, action patterns, correlations, explanations, reasons (cf [17]) in categories, schemes and models. On this basis, Eichhorn [18] describes a model for the development of vocational competence in the laboratory work domain. The object-related knowledge structures are a first differentiation criterion for different competence levels. A secondly essential differentiation criterion for competence levels is the degree of selfmonitoring and self-controlling of the subjectively available task-related cognitive resources and strategies [18], [19]. This approach was used by Eichhorn and Niethammer [20] on the domain ―teaching― to obtain orientations for the creation and evaluation of competence oriented teacher training. A phase model for subject or profession-related didactical competence development is created on the basis of the scaling criteria as mentioned above, from which the indicators for the evaluation of professionally or subject-related didactical competence can be deduced. Unlike teaching beginners, teaching experts pay less attention to superficial, irrelevant details according to the activity flow, since they are skilled in categories and event schemes to analyse and create the teacher and student activity structures [21]. In this case, categories, cognitive schemes and mental models have to represent the high-level complexity of the scope of action ―teaching.― The adequate representation of the non-separable (multidimensional) aim-content-method relation is of particular importance. The interdependent methodological dimensions (teaching and learning steps, action patterns and social structures, teaching aids) are to be created by an interdependence towards the aims and content of the teaching and learning process. Firstly, in this respect, the categories, cognitive schemes and mental models have to be able to be extended/modified for the sphere of competence ―teaching― to represent this adequately, and secondly, to be activated on demand as well as appropriately for any particular situation. In particular, the differentiation between the schemes and mental models should be emphasised. By schemes, primarily superficial aspects of the didactic and methodological scope of action are represented (episodic and categorical representation of ordinary situations, action patterns, etc.). Mental models are necessary to give reasons for the usefulness of an action pattern, a lesson or to plan teaching and learning processes which reflect their essential aspects (hypothetical representations). In parallel with the selectively appropriate activation of these cognitive units, these are evaluated and elaborated in multiple (also new) contexts, i.e. enriched, modified or even substantially altered (cf [20]). Additionally, subjectrelated knowledge structures are required for the reflecting, controlling and modifying of the existing object-related knowledge structures (so-called ―meta-knowledge―) by which a self-monitoring and self-controlling function is realised. th nd Joint International IGIP-SEFI Annual Conference 2010, 19 - 22 September 2010, Trnava, Slovakia Performance and behaviour in teaching situations of varying complexity and complicatedness are indicators of the competence levels achieved by the teacher students. The following indicators can be used for the competence level II of didactic competence which has to be developed at first during the teacher education: recognition of important superficial situational elements - characterisation of episodic representations through didactic-methodological categories and schemes (use and testing of adopted categoric representations such as teacher personality, student activity, use of teaching aids), recognition of important essential situational elements - reasons and explanations for superficial situational elements (categorical representations, especially schemes) through adopted mental models (hypothetical representations), e.g. cognitive ways, components of action regulation and their reflection and adaption, self-monitoring and self-controlling. 3.2 Approach for a Competence Oriented, (Self-)Reflective Teacher Education4 A better understanding, diagnosis and handling of the students‘ developmental problems or barriers in the sphere of competence ―teaching― can be realised by means of the introduced indicators. Newcomers, i.e. first-year teacher students, start with very different qualifications. In particular, existing schemes referring teaching play a major role in teaching oriented competence development. Generally, they correspond to the episodic representations, and they are formed by reflecting experienced lessons from a student‘s point of view. These schemes determine the subjective students‘ theory concerning teaching methods. They may disapprove the structures of the professional knowledge that is imparted. In this case, there are no correlations between the available schemes and the provided schemes/mental models in the study course for the persons concerned. The new content is retained without any interconnection to personal understanding of pedagogical activity [1] and therefore, they cannot be guiding principles. A starting point for competence oriented teacher training is to ensure the acquisition of teaching experiences which form a basis for building schemes (episodic representations), which motivate and allow correlations with the aimed professional knowledge and to initiate and foster the further development of episodic representations to categorical and hypothetical representations by combining the teaching experiences with externally provided or internally generated professional knowledge. 3.2.1 Gaining teaching experiences which motivate and allow correlations with the aimed professional knowledge (categorical representations) This precondition is established, e.g. for teacher students studying the subject environmental technology, through a comprehensive one-week project (about a technical subject) in which the students take the part of learners and experience problem-oriented and learner-centred lessons from this perspective. Many of them gain this kind of learning experiences for the first time. These experiences from a learner‘s perspective become a point of reference and orientation for the didactical th nd Joint International IGIP-SEFI Annual Conference 2010, 19 - 22 September 2010, Trnava, Slovakia studies. They ensure a correlation with the professional knowledge even if it is provided in traditional lectures. Independently of this fundamental importance for teacher training, the students acquire competences in environmental analysis within the project [22]. 3.2.2 Further development of the schemes in terms of acquiring categorical representations and the transfer into mental models (hypothetical representations) The students have to gain repeated experiences with similar episodes for further development of the schemes (in terms of acquiring categorical representations) or the transfer into mental models (hypothetical representations). For that purpose, the work with teaching episodes on two levels is applied intentionally in subject-related or professional didactical seminars. The students receive tasks to analyse and evaluate teaching concepts as well as to develop alternatives (=analysis of case studies in terms of Stated Problem Method), if applicable, or for conceptual development and demonstration of teaching methods (= development of new approaches for a case study). Concerning the case study selection the students have to face, it has to be considered that good didactical approaches are less reflected in depth than poor ones. Good approaches always seem simple and easily accessible. They are accepted as „standard.― For the teaching beginner may rise the impression that he can manage this as well. In order to counteract this (mistaken) competence sensation, the case studies have to be chosen and designed in such a way that certain didactical aspects (connections between teacher activity and the initiated learning process) are focused by means of mistakes in the teaching concept. In doing so, a specific schemes or mental models development can be initiated and assisted [23]. The conceptual planning and demonstration of new or alternative teaching concepts (as case studies) serves to realise a productive application of the schemes/mental models and by means of that to carry out their elaboration. This requires that the students have already internalised these and see that their application for lesson planning is useful. The teaching concepts are demonstrated in the seminars by role playing. The learner roles are determined and personified by reflection of learner types beforehand. Hence, the planning and performance of teaching sequences is related to the pro-active and class-related diagnosis of learner performance and behaviour. In principle, the evaluation of the teaching sequences starts with a feedback on the learner roles‘ point of view. On this issue, two effects are expected: students, who take the learner roles train their empathy as well as diagnostic capabilities. Those who take the teacher role receive a feedback on their recipients‘ group view, whereby the initiated learning process comes to the fore as a result of teacher activity. All in all, firstly, the conscious perception of the shown teaching and learning processes is fostered in such a manner. Secondly, the basically subjective theories are made aware of by the explanations and optimisation of the acquired teaching and learning processes in evaluation meetings and made accessible by the extension/ adaptation towards the aimed professional knowledge. Thus, internal and partly unconsciously running cognitive processes of the teacher can be externalised and th nd Joint International IGIP-SEFI Annual Conference 2010, 19 - 22 September 2010, Trnava, Slovakia therewith visualised or made conscious, so that reflective learning is initiated [24]. The presented concepts were tested successfully in each case, whereas the effects could be proven partially [20]. Based on these results, the concepts are not only specified and evaluated onwards, but continuously developed into a situated learning environment to foster the development of didactical professionalism as an overall concept for learning on teaching episodes in a competence level system. 3.3 Evaluation of the Effectiveness of the Approach Studies concerning the effectiveness of teacher training approaches are relatively rare and allow barely clear and comprehensive statements. ([25], [26], [27]) The stage of development of appropriate instruments has to be assessed likewise. In fact, it was proven that the attention aspects of the participants changed during the work on video-based teaching sequences5 [28]; the participants extended their knowledge of didactical options [29] or had relevant knowledge of more uniform criteria for teaching evaluation [30]. However, it could not be clarified to what extent the probands could produce correlations between the visual teaching phenomenons and didactical deep structures of the teaching and the learning process. Recording only the pedagogical content knowledge (PCK) [31] is insufficient because just its application for the clarification, explanation and evaluation of teaching phenomenons (reflection and assessment competence) is an indicator for the didactical knowledge networking with teaching phenomenons, and therefore for its effectiveness6. Bischoff developed a video test based on standard teaching situations which have be to evaluated by the probands. It almost meets the goal. Here is recorded to what extent the probands recognise difficult teaching sequences and may suggest a suitable option. It is not recorded in what way the probands may be able to recognise and explain the nature or the inner reasons of difficult teaching situations on the basis of their professional knowledge [32]. Our effectiveness studies aim at the verification of the following hypotheses: The work on teaching situations (teaching reflection) has the potential to acquire (effectively) professional knowledge as a basis for teaching competence. The effectiveness of the acquired professional knowledge is connected to its specific quality (kind of cognitive organisation and processing (elaboration)) (cf [27]). Therefore, knowledge is recorded which is used to describe, explain or justify as well as optimise teaching situations (see 3.1). This is done by test procedures because other evaluation types (self-assessment, observation and teaching or learner performance evaluation) provide only little objective and hardly reliable statements [33]. For the tests, the students have to face a specially chosen or designed teaching situation (simulated, video-based, transcribed, recorded film sequence). Performance and behaviour are recorded during the analysis, evaluation and optimisation or creation of the teaching and learning process. These data can be correlated additionally with data on subjective competence sensation (self-assessment). That way Diedtemann [23] verified the effectiveness of the work on case study situations for the professional knowledge development following this approach. Therefore, she developed a categorisation system for qualitative content analysis of provided teaching sequences (didactically relevant characteristics of teaching situations: th nd Joint International IGIP-SEFI Annual Conference 2010, 19 - 22 September 2010, Trnava, Slovakia learning content, didactical functions, methodological concept, teacher-studentinteraction, perception aiding resources, etc.) and analysed the students‘ evaluation of these teaching sequences regarding the recognition of these characteristics. Hübner [24] demonstrated the effectiveness of the didactical role play approach 7 in a similar way. She recorded the students‘ remarks in the role play reflection phases (referred to the realised roles teacher, learner or observer in each case) and organised them by the teaching concept dimensions (teaching/learning steps, action patterns, social methods, media) differentiated according to essential and superficial aspects.
