Abstract

Background: Clinical biochemistry is a branch of organic chemistry which involves a detailed study on the normal functioning of living cells in relation to the disease. The subject is not only volatile but also complicated. Also, teaching biochemistry to medical undergraduates is really a challenging job. Routine didactic lectures alone may not be enough for students while learning clinical biochemistry.

Methods: This study included 90 first-year medical undergraduate students. They were grouped as three groups of 30 students each. The routine conventional classroom teaching method was followed by a group discussion session. The topics were informed in advance so that they were provided with adequate time to prepare and be mentally ready for the session. The group discussion was preceded by a set of 10 multiple-choice questions (MCQs), and a final assessment of five MCQs following the discussion.

Results: There was only minor difference in the marks obtained by various student groups after the group discussion with Group B students (5.5 ± 1.54; p < 0.001) performing better than the other two groups. Students also scored evenly in the final assessment using MCQs with Group A (2.7 ± 1.36; p < 0.001) performing better than the other two groups. Prior to the group discussion session, 33% of the students in all the groups scored more than 75% of marks. The overall performance of all the students after the final assessment using MCQs revealed that 60% of the students scored more than 75% marks.

Conclusion: The study results confirm the fact that the modified conventional teaching method appears to be better than traditional teaching. The student performances had significantly improved with such kind of education process. The results also highlight the importance of increased student efforts, probably including group discussions and revisions to improve understanding and subject retention.

The flipped classroom stimulates greater learning and is a modern 21st century approach to teaching today's undergraduates.

C Mortensen, A Nicholson (2015)

Many classrooms in higher education still rely on a transformative approach to teaching where students attend lectures and earn course grades through examination. In the modern age, traditional lectures are argued by some as obsolete and do not address the learning needs of today’s students. An emerging pedagogical approach is the concept of the flipped classroom. The flipped classroom can simply be described as students viewing asynchronous video lectures on their own and then engaging in active learning during scheduled class times. In this study, we examined the flipped classroom teaching environment on student learning gains in an Introduction to Equine Science course. Students (n = 130) were asked to view 7.5 h of recorded lectures divided into 8 learning modules, take online quizzes to enforce lecture viewing, take 3 in-class exams, and prepare to participate in active learning during scheduled class times. Active learning approaches included individual activities, paired activities, informal small groups, and large group activities. When compared to students in the traditional lecture format in earlier years, students in the flipped format scored higher on all 3 exams (P < 0.05), with both formats taught by the same instructor. Analysis of ACT scores demonstrated no intellectual capacity differences between the student populations. To evaluate any gains in critical thinking, flipped format students were asked to take the Cornell Critical Thinking Exam (version X). Scores improved from the pretest (50.8 ± 0.57) to the posttest (54.4 ± 0.58; P < 0.01). In the flipped course, no correlations were found with student performance and interactions with online content. Students were asked in class to evaluate their experiences based on a 5-point Likert scale: 1 (strongly disagree) to 5 (strongly agree). The flipped classroom was ranked as an enjoyable learning experience with a mean of 4.4 ± 0.10, while students responded positively to other pointed questions. In formal course evaluations, flipped format students ranked the following higher (P < 0.05): instructor availability to assist students; encouragement of independent, creative, and critical thinking; and amount learned. Overall, the flipped classroom proved to be a positive learning experience for students. As the classroom continues to modernize, pedagogical approaches such as the flipped classroom should be considered for many lecture-style courses taught in the animal sciences.

Concept and benefits of the Inverted Classroom method for a competency-based biochemistry course in the pre-clinical stage of a human medicine course of studies

Susanne Kühl, Matthias Toberer, Oliver Keis … (2017)

Background: Medical students often have a problem recognising the relevance of basic science subjects for their later professional work in the pre-clinical stage of their studies. This can lead to a lower motivation to learn biochemical content and dissatisfaction in the courses amongst the students. Alternative teaching methods such as the Inverted Classroom (IC) method can address this deficiency. The goal of this study was: to analyse the motivation and satisfaction of the students in a biochemistry seminar through the use of the e-learning-based IC method, to investigate the acceptance against the IC teaching method in biochemistry, and to compare the learning success achieved using the IC approach with that of a traditional course. We also investigated how a biochemistry course in the pre-clinical stage of a human medicine course of studies can be successfully organised according to the IC method. Furthermore, we examined the benefits of the IC method over conventional teaching formats. Method: The IC method was implemented in accordance with the guidelines of the GMA committee “New Media” [30] in a biochemistry seminar for two student IC intervention groups with 42 students. A part of the factual knowledge from the on-site phase in the form of teaching videos together with self-learning control tasks were provided online before the seminar for both IC intervention groups. Exporting content to the self-learning phase creates new free time in the on-site phase, during which the content can be critically considered and processed and additional competency-based learning objectives can be taught. Identical biochemistry teaching content was taught in parallel control groups (14 student groups with n=299 students), but no material was handed out beforehand for a self-learning phase. These students only received the materials after the on-site phase. Motivation and satisfaction as well as the acceptance for the teaching methods were recorded by questionnaires, the acquisition of knowledge by MC exams. Results: On a Likert scale from 1 (strongly disagree) to 6 (strongly agree), the students in the IC intervention groups could be seen to be much more motivated (5.53) than students in the control group (4.01). Students in the IC intervention groups also recognised the relevance of the learning content much more clearly (5.44) than students in the control group (4.01). Furthermore, the IC group also observed that additional competencies were trained in addition to the biochemistry content. In addition, the IC intervention group award the event a school grade of 1.53, the traditional control group a grade of 2.96. The teaching videos were rated very positively by both groups with an average school grade of 1.3 in each case. A qualitative analysis showed that the motivation and a positive attitude of the lecturers played a decisive role in the successful implementation of the IC method. Discussion and conclusion: Pre-clinical students display a high acceptance of the e-learning-based IC method. Teaching communication competencies in a biochemistry seminar was also rated very positively by the students. The quality of the teaching video and the motivation of the lecturers were shown to be a critical parameter for the successful performance of the IC method. What’s more, the IC method can contribute to implementing a competence orientation in medical studies.

The relationship between non-cognitive student attributes and academic achievements in a flipped learning classroom of a pre-dental science course

Minsun Kim, Sangho Roh, Jungjoon Ihm (2018)

Purpose The purpose of this study was to examine whether non-cognitive student attributes such as learning style and personality type affected academic performance in a flipped learning classroom of a pre-dental undergraduate science course. Methods ‘Biodiversity and Global Environment,’ a 15-week, 3-credit course, was designed as a flipped class in Seoul National University School of Dentistry in 2017. Second-year pre-dental students were required to enroll in the course and to engage in online learning and in-class discussion. The Kolb’s Learning Style Inventory and the Myers-Briggs Type Indicator were conducted to measure non-cognitive student factors. Independent samples t-test and multivariate regression analyses were used to examine the relationships between self-rated measurements and academic achievement. Results More than half of the students enrolled in the flipped science course had an assimilator learning style (50%), followed by convergers (24%), accommodators (16%), and divergers (10%), and their personality types were dominated by the introverted, sensing, thinking, and judging types, respectively. Examining group differences using the t-test demonstrated a significant relationship between the diverger group and higher academic success. In particular, the multivariate regression analysis indicated that both thinking types and female students performed better in discussion than feeling types and male students. Conclusion To operate the flipped learning classroom more effectively in medical and dental education, the instructor should carefully develop and apply a more tailored facilitation and relevant assessment by considering student learning styles and personality types.
