Abstract Background Growing demand for student-centered learning (SCL) has been observed in higher education settings including dentistry. However, application of SCL in dental education is limited. ...Hence, this study aimed to facilitate SCL application in dentistry utilising a decision tree machine learning (ML) technique to map dental students’ preferred learning styles (LS) with suitable instructional strategies (IS) as a promising approach to develop an IS recommender tool for dental students. Methods A total of 255 dental students in Universiti Malaya completed the modified Index of Learning Styles (m-ILS) questionnaire containing 44 items which classified them into their respective LS. The collected data, referred to as dataset, was used in a decision tree supervised learning to automate the mapping of students' learning styles with the most suitable IS. The accuracy of the ML-empowered IS recommender tool was then evaluated. Results The application of a decision tree model in the automation process of the mapping between LS (input) and IS (target output) was able to instantly generate the list of suitable instructional strategies for each dental student. The IS recommender tool demonstrated perfect precision and recall for overall model accuracy, suggesting a good sensitivity and specificity in mapping LS with IS. Conclusion The decision tree ML empowered IS recommender tool was proven to be accurate at matching dental students’ learning styles with the relevant instructional strategies. This tool provides a workable path to planning student-centered lessons or modules that potentially will enhance the learning experience of the students.
Project-oriented problem based learning (POPBL) is an alternative approach to innovative teaching and is widely implemented in the classroom. However, little information is gathered pertaining to its ...implementation in psychology-related subjects. The present study is guided by two objectives: 1) to examine students’ perception of this type of approach, and (2) to determine whether students’ perception improves after the implementation of POPBL. 103 participants aged between 18-24 years old (M = 21.91, SD = 2.14) participated in this study. A measure, named the Students’ Learning Experience Scale (SLES) was constructed to determine participants’ perception of their learning in five aspects: (1) acquired knowledge, (2) soft skills, (3) contribution and engagement, (4) sustainability; and (5) assessments. The results from the present study suggested that the POPBL was indeed highly acceptable and favored by all students. A paired t-test was also conducted to evaluate the effectiveness of the approach on students’ scores on the SLES. The results show that there was a significant difference in the scores for students’ perception of the course before (M = 4.15, SD = .45) and after (M = 4.41, SD = .40); t(87) = (-4.05). p = .000. These findings were further discussed with respect to the current literature on teaching and learning approaches, and the significant implications in developing effective pedagogic strategies.
