Personality Type, Learning Modalities and Academic Performance in Undergraduate Engineering Adele H.T. Kam, H.P. Chionh, R. Ram, C.H. Goh INTI International College Penang, Malaysia adele@intipen.edu.my Abstract: The purpose of this study was to investigate the extent to which academic performance of engineering students are associated with variables related to the realm of learning, specifically personality type and learning styles. The Myers Briggs Type Indicator® was administered to a group of 85 students and the VARK inventory to 123 students from the School of Engineering and Technology at INTI International College Penang. Observations made showed that students who preferred the MBTI® Thinking dimension performed significantly better academically compared to students who preferred the Feeling dimension. There was no significant difference in academic performance associated with the other personality dimensions or any of the VARK learning modes. The MBTI® and VARK inventories assessed independent aspects of learning which were useful for consideration in course design. Recommendations according to the research findings were made. Introduction One of the challenges of educators in the classroom is to find effective ways of teaching that can enhance the learning process and hence improve academic performance of their students. This is essentially important in engineering education where attrition rates can be high and the understanding of factors that affect academic performance can be applied to enhance student retention. Two factors that have been broadly explored are learning styles and personality types. The Myers Briggs Type Indicator®, MBTI® (Myers and McCaulley, 1985) has been widely used to assess personality type and learning styles. It has been employed in research to investigate the relationship between learning styles and academic performance of engineering students (Rosati, 1997; Felder et. al, 2002; Felder and Brent, 2005) as well as studies concerning the effects of personality type in engineering education (McCaulley et. al, 1983; O’Brien et. al, 1998). One objective of this study is to investigate the relationship between students’ personality type and learning styles identified through the MBTI® preferences and their academic performance in the engineering faculty of INTI International College Penang (IICP). A learning style is the method of learning particular to an individual that is presumed to allow that individual to learn best. To date, there are numerous models and theories to describe learning styles (Felder, 1996), MBTI®, being one of them. Another commonly known model is VARK (Fleming and Mills, 1992), which emphasizes the preferences of taking in and giving out information through sensory channels. The VARK instrument helps to identify whether a person prefers to take in stimuli through visual, aural, read-write or kinesthetic representation. These representations are commonly found in classroom experiences and investigating the relationship between students’ preferences for these learning modes and their academic performance may yield useful information for classroom design considerations, the second objective of this study. Apart from investigating whether the academic performance of students is dependent on their personality type and learning styles, this paper also describes the distribution of personality types and learning styles of the engineering students at IICP. Implications of these findings for teaching and learning are also discussed. Personality Type and Learning Style Models The Myers Briggs Type Indicator®, MBTI® (Myers and McCaulley, 1985), is a reliable and validated inventory that assesses a person’s personality type. It is based on Jung’s personality theory (Jung, 1923), which identifies an individual’s orientation of energy and their basic mental functions. Jung identified that an individual would have an inborn tendency to either focus their energy outwardly (Extraversion) or inwardly (Introversion). He also identified four basic mental functions, two opposite ways for perceiving information (Sensing and Intuition), and two opposite ways to making judgment (Thinking and Feeling). The MBTI® was developed to implement Jung’s theory so that it could be applied and examined empirically. While the MBTI® purports to measure personality preferences, it also measures a number of constructs, cognitive in nature, which relate to the concept of learning styles. The MBTI® type preferences can be combined to form 16 different personality and learning style types (Lawrence, 1982; Lawrence, 1997). Characteristics of each style are summarized in Table 1. Table 1: Learning Style Characteristics for each Personality Preference Personality Function Learning Style Characteristic Preference Extraversion (E) Energy is directed outwards, focus Learn best through interacting with on events and people in the outer people, action and things world Introversion (I) Energy is directed inwards, focus on Learn best through quiet reflection internal thoughts and ideas and individual ways Sensing (S) Takes in information through the Learn best through concrete five senses, focus on concrete facts experience, moving step by step with and experiences known things to the abstract Intuition (N) Takes in information through Learn best through inspiration, patterns and associations, focus on starting with concepts before practical imagination and possibilities details Thinking (T) Make decisions using logical Learn best through clear logical reasoning, focus on objectivity and material, analyzing experiences to people’s thoughts find objective truth Feeling (F) Make decisions using personal Learn best through personal values, focus on harmony and relationships, personalizing issues people’s feelings and causes that are important Judging (J) Oriented to the outer world in a Learn best through instruction that is planned and controlled manner, organized and which moves in focus on making decisions and predictable ways, toward closure setting limits Perceiving (P) Oriented to the outer world in a Learn best through stimulation of flexible and spontaneous manner, something new and different, focus on exploring options and opportunity for open exploration being resourceful The VARK (Fleming and Mills, 1992) is an acronym for Visual, Aural, Read-Write and Kinesthetic and is another instrument widely used to identify the learning modes of students. The inventory includes a systematic presentation of questions to identify the preferred learning modalities of a student. Visual learners prefer the use of diagrams, pictures, videos, slides, graphs and flow charts to represent printed information. They may also favor teachers who use gestures and facial expressions. Aural learners concentrate on what teachers and people say. They prefer to listen rather than take notes and tend to remember interesting examples or stories. To aid their learning, aural learners may discuss and explain ideas to others or put summarized notes onto tapes and listen to them. Read-write learners prefer printed words and text as a means of taking in information, for instance, textbooks, lecture notes and handouts. These learners benefit from turning reactions, actions and diagrams into words and practicing writing exam answers. Kinesthetic preference refers to learning achieved through the use of experience and practice. Kinesthetic learners learn through engaging their five senses, real-life examples, handson approaches and role-plays. Methodology The MBTI® Form G questionnaire and VARK Learning Modes Inventory were administered to the engineering students at IICP through organized workshops and classroom participation respectively. 85 students completed the MBTI® Form G and 123 students completed the VARK inventory. Participation was from various cohorts of students and voluntary. Student MBTI® preferences were obtained through the tabulation of the Form G questionnaire while VARK preferences were calculated by the VARK scoring spreadsheet (details provided at www.varklearn.com) after totaling the visual, aural, read-write and kinesthetic scores. The generated VARK results would indicate the preferred learning mode(s) for an individual, which may consist of only one mode (single modal) or a combination of two or more modes (multi-modal). Basic descriptive statistics were utilized to evaluate the distribution of personality types and learning styles of engineering students. Independent samples t-tests and analysis of variance (ANOVA) were used to explore potential significant differences in academic performance related to differences in personality types and learning styles. Academic performance is measured using the cumulative average (CAVG) scores of the student. Results and Discussion Distribution of MBTI® personality type and learning styles among engineering students Descriptive statistics revealed the following distribution of personality preferences among the 85 engineering students included in the study: (a) Extroversion 40 (47%), Introversion 45 (53%) (b) Sensing 50 (59%), Intuition 35 (41%) (c) Thinking 30 (35%), Feeling 55 (65%) (d) Judging 34 (40%), Perceiving 51 (60%) This distribution shows that the majority of engineering students in this study are Introvert, Sensing, Feeling and Perceiving. This is considered an atypical distribution as previous studies (McCaulley, 1983) observed that engineering students tend to have preferences for Thinking (74%) and Judging (61%) but the reverse is observed at IICP with Feeling and Perceiving as the majority types. Demographically, 18 (21%) students were female and 67 (79%) students were male. In regard to academic performance, cumulative average (CAVG) scores ranged from 21.94 to 88.0 on a 100 point scale; a range of 66.06. The mean CAVG for the sample is 60.33 with a standard deviation of 13.73. MBTI® Personality type and academic performance Independent sample t-tests were used to compare the academic performance (CAVG) between students who either preferred Extraversion or Introversion, Sensing or Intuition, Thinking or Feeling and Judging or Perceiving. Table 2 presents the results of this test.

However the difference in academic performance between students with preference for Thinking or Feeling was highly significant (t (83) = 3.629, p<0.001). The 95% confidence interval for mean difference was 4.78 to 16.36. The effect size, d, was 0.82. For the Social Sciences and organizational research, a small effect is viewed as a “d” of about 0.2, a medium effect, about 0.5, and a large effect, 0.8 or more (Cohen, 1988). The academic performance of students who preferred Thinking was significantly higher than those who preferred Feeling, and the effect size was large. This finding is consistent with those of prior studies (Godleski, 1984; Rosati, 1993; Rosati, 1997; Felder, 2002) and with type theory, which suggests that the objective and impersonal nature of engineering subjects would be conducive for students who preferred Thinking but may not be engaging for students who preferred Feeling. This suggests a need for a better balance in the course design between technical and social aspects of engineering. More so, given the fact that the majority of engineering students at IICP had a preference for the Feeling function. However, the observation made in prior studies (McCaulley, 1983; Rosati, 1993; Rosati, 1997) that students with preference for Introversion, Intuition and Judging outperformed their opposite counterparts did not emerge in this study. Distribution of VARK learning modes among engineering students The distribution of learning modes among the 123 engineering students included in this study is as shown in Figure 1. 50% (62) of the students demonstrated a single mode of preference while another 50% (61) demonstrated multi-modal preferences. Among the students who had a single mode of preference, the kinesthetic preference is the most dominant (25%), followed by Aural (17%). The least preferred mode was Visual (2%). Multi-modal students comprise of those who had preferences for two or more of the VARK modes with 20% being Bi-Modal, 11% being TriModal and 20% having preference for all the VARK modes. Demographically, 31 (25%) students were female and 92 (75%) students were male.

The descriptive statistics are presented in Table 3. The results showed that there was no significant difference in performance across the four groups (F (3,119) = 1.508, p = 0.216). Table 3: Descriptive statistics for CAVG with 1,2,3 & 4 modalities (VARK) No of modality N Mean Std dev 1 62 63.37 11.46 2 24 66.01 10.80 3 13 66.93 13.37 4 24 59.85 12.52 Independent samples t-tests were used to determine whether academic achievement was associated with a preference for a particular VARK mode. This was accomplished by comparing whether the academic performance (CAVG) of V and non-V students was significantly different. Similarly, t-tests were carried out to compare performances of A and non-A students, R and non- R students and K and non-K students. Table 4 shows the results of this test. The results showed that there was no significant difference in performance between V and non-V, A and non-A, etc., which indicated that academic achievement of the engineering students did not depend on their learning mode preferences.

Most engineering faculties teach using the lecture method, where information is presented through visuals, the spoken or the written word. In this way, students who preferred either the visual, aural or read-write modes would have an opportunity to receive information through their preferred channels. Students who preferred the kinesthetic modality however may prefer to learn through active experimentation and direct experience. These approaches may be used in laboratory sessions but are not the norm in lectures as additional time, resource and planning are often required to incorporate practical activities. It was initially hypothesized that kinesthetic students may attain lower academic scores for these reasons but it was not so. There are a few possible explanations for this. Firstly, kinesthetic students may also benefit from doing tutorials that provide practice exercises and solution samples and this is commonly practiced at IICP. Secondly, lecturers themselves differ in the way they teach, some giving more emphasis on visuals, some on speaking, some on hands-on activities, and so forth. The cumulative effect of this is that students of any learning mode should not be permanently disadvantaged as they take differing subjects by differing lecturers, hence obtaining a CAVG that does not differ significantly. It is possible that learning modes may play a significant role if results of specific subject scores, taking into account the teaching style of the lecturer concerned, are tested with student learning style preferences, an implication for future research. Another initial assumption was that multi-modal students would have better academic performance compared to those who are single-modal since multi-modal students may adapt more easily to differing lecturing styles. Statistical results however, showed no significant difference between these two groups. While some multi-modal students would benefit from their ability to match their preferences with whatever mode(s) being used, there may be others who need to have at least two, three or four modes involved in learning before they feel satisfied or secure. This could be a disadvantage compared to students with single preference who may “get it” once the information channel aligns with their preference. For this reason, multi-modal students are not necessarily advantaged for academic performance as reflected by the results. Correlation test between MBTI® learning styles and VARK modes As two instruments for learning styles were used in this study, a test to investigate whether any of the MBTI® learning styles correlated to the VARK modes was done. This serves to confirm that each instrument sought to assess separate cognitive aspects in determining learning preferences. Chi-square test of association was performed to find out whether there was an association between each of the MBTI® dichotomy (E-I, S-N, T-F, J-P) and each of the VARK modality (V,A,R,K). For example, Chi-square test of E-I against V (Visual and Non-Visual) was used to find out whether a person’s preference for Extraversion or Introversion is related to the visual modality (V or non-V). In other words, the test attempted to find out whether the proportion of visual mode in extrovert students was different from the proportion of visual mode in introvert students. This approach was repeated between other MBTI® dichotomies and VARK modes. The result of 16 Chi-square tests performed is shown in Table 5. None of the test was significant at 0.05 level of significant. This implies that MBTI dichotomies are not related to VARK modality.

VARK, on the other hand, identifies the preferred sensory channel to receive information, which is independent of the MBTI® Sensing and Intuition predisposition. It is associated with the MBTI® Sensing dimension but does not overlap with the other aspects assessed by the MBTI® as confirmed by the results. Conclusion Comparing individual personality types and cumulative average scores clearly showed that engineering students who preferred Thinking performed better than those who preferred Feeling. This finding strongly suggests that consideration needs to be given to balance the course design between technical and social aspects of engineering in order to increase its relevance to Feeling learners. This ought to be emphasized since a substantially large majority of engineering students at IICP recorded a preference for Feeling. It may be beneficial to employ a systematic approach to analyzing the differing needs of Thinking and Feeling students, and then providing them with different types of learning opportunities highly congruent with their respective styles to reduce this variance in academic performance. According to type theory, Feeling learners tend to appreciate personal motivation from their teachers and relationships are critical in encouraging them to pursue an interest. There was however, no significant difference in the cumulative average scores between differing personalities in the other dichotomies. Future research however, could be implemented to observe if personality type would have a greater effect on students at the lower end of the academic spectrum compared to the better students as noted by Rosati (Rosati, 1993; Rosati, 1997). Comparisons between VARK learning modes and cumulative averages showed that academic performance is not associated with the preference for any particular mode or the number of modes. Students of differing learning modes showed equal achievement academically. Likewise, for students who were single modal in comparison to those who were multi-modal. Majority of the engineering students had a preference for the kinesthetic modality. While there was no significant difference in the academic performance of this group of students compared to the other groups, it would be beneficial to take into account their learning needs as it may improve the level of student satisfaction for the curriculum and learning environment. A lecture style classroom tends to rely more on one-way communication and written text, which rarely gives opportunity for a student to learn through practical and experiential ways. Perhaps Asian students are somewhat used to more passive ways of learning and have little expectation of other alternatives but incorporating experiential learning into the classroom would probably yield higher levels of engagement and motivation especially from the kinesthetic students. Although the results of this study imply that consideration of learning modes in course design is less critical, it is good practice to utilize multiple modes in our teaching. If this is done, the students will be taught in a manner that suits their preferences at least for part of the time and yet push them to function in their less preferred modes at other times, helping them to balance their skills in those modes. The MBTI® dimensions and the VARK modes have been found to measure independent aspects of learning styles as results show no correlation between these two inventories. The former measures inborn mental functions while the latter measures the preferred sensory channel. Both inventories have been used in this study to understand the factors that contribute to academic performance of engineering students. The insights obtained have been applied in the consideration of course design.
