The belief that it is unwise to alter the initial response to a multiple choice question is questioned. Among 39 380 MCQ responses, there were 1818 changes (4.62%) of which 21.9% were correct to incorrect responses, 46.3% incorrect to correct responses and 31.8% incorrect to incorrect. This effect was very much more marked among the better students, incorrect to correct changes accounting for 61% of the responses in the upper group, 42% in the middle group and 34% in the lower group.

A rationale for selecting suitable physiology topics for the basic sciences curriculum in dentistry

Jiffry MT, Husain R, Dias AP

Med Educ, 1987 Jan;21(1):38-45.

PMID: 3821599

The suitability of physiology topics taught in the first-year dental curriculum needs to be investigated in the light of the view of the present generation of clinical and preclinical teachers, and students. This was studied in the University of Malaya in order to propose a rational physiology curriculum with proper identification of priority topics. Oral physiology, blood and the cardiovascular system were found to be the most relevant for dental students. Among the systems, high and low priority topics were identified and their relative importance is discussed.

The influence of laboratory experimental work on concept acquisition in a medical physiology course with implications for curriculum deliberations and instructional design

Tan CM

Med Teach, 1990;12(1):83-90.

PMID: 2233187

Following revision of the curriculum the effectiveness of a traditional cookbook experiment, used in conjunction with an 'interpretation seminar', was evaluated. Curriculum revision had been predominantly concerned with an avoidance of overloading and provision of self-study periods. The preceding lectures were integrated with the experiment. The learning resulting from the practical experience was assessed using pre- and post-tests. The practical exercise was ineffective and did not facilitate conceptual understanding. Due to the central role of passive teaching methods the students adopted a surface approach to all learning, were teacher dependent and did not make effective use of their private study. Furthermore, owing to a broad-based entry into medical school many students lacked the basic skills essential to the achievement of meaningful learning. Clearly, for effective learning the curriculum and pedagogy must be geared to the background and educational needs of the students.

PMID: 20522904 DOI: 10.1152/advan.00025.2010

This study tested the possibility that interactive lectures explicitly based on activating learners' prior knowledge and driven by a series of logical questions might enhance the effectiveness of lectures. A class of 54 students doing the respiratory system course in the second year of the Bachelor of Medicine and Bachelor of Surgery program in my university was randomized to two groups to receive one of two types of lectures, "typical" lectures (n = 28, 18 women and 10 men) or "constructivist" lectures (n = 26, 19 women and 7 men), on the same topic: the regulation of respiration. Student pretest scores in the two groups were comparable (P > 0.1). Students that received the constructivist lectures did much better in the posttest conducted immediately after the lectures (6.8 +/- 3.4 for constructivist lectures vs. 4.2 +/- 2.3 for typical lectures, means +/- SD, P = 0.004). Although both types of lectures were well received, students that received the constructivist lectures appeared to have been more satisfied with their learning experience. However, on a posttest conducted 4 mo later, scores obtained by students in the two groups were not any different (6.9 +/- 3 for constructivist lectures vs. 6.9 +/- 3.7 for typical lectures, P = 0.94). This study adds to the increasing body of evidence that there is a case for the use of interactive lectures that make the construction of knowledge and understanding explicit, easy, and enjoyable to learners.

What is the ultimate goal in acid-base regulation?

Balakrishnan S, Gopalakrishnan M, Alagesan M, Prakash ES

Adv Physiol Educ, 2007 Mar;31(1):51-4.

PMID: 17327583

It is common to see chapters on acid-base physiology state that the goal of acid-base regulatory mechanisms is to maintain the pH of arterial plasma and not arterial Pco(2) (Pa(CO(2))) or plasma HCO(3). A hypothetical situation in which the Pa(CO(2)) of arterial plasma is 80 mmHg and the plasma HCO(3) concentration is 48 mM is presented and analyzed to get over this misconception. As per the modified Henderson equation, the pH of arterial plasma would be 7.4; however, we explain that this may be associated with intracellular acidosis due to intracellular hypercapnia and that derangement of homeostasis is evident from the occurrence of respiratory depression and, eventually, coma in the patient described. This suggests that the ultimate goal of acid-base regulatory mechanisms is not just the maintenance of the pH of arterial plasma but the maintenance of the steady-state pH of intracellular fluid as well.

Clinically oriented physiology teaching: strategy for developing critical-thinking skills in undergraduate medical students

Abraham RR, Upadhya S, Torke S, Ramnarayan K

Adv Physiol Educ, 2004 Dec;28(1-4):102-4.

PMID: 15319191

Medicine is an applied science, interpreting evidence and applying it to real life by using clinical reasoning skills and experience. COPT (clinically oriented physiology teaching) was incorporated in physiology instruction aiming to relate the study of physiology to real-life problems, to generate enthusiasm and motivation for learning, and to demonstrate the vocational relevance of physiology among students by integrating clinical experience with teaching. COPT consisted of two elements: 1) critical-thinking questions (CTQ) and 2) clinical case studies. After a few topics were taught, CTQ and case studies were given as an assignment. Answers were discussed in the next class. Two exams, each of which contained CTQ and recall questions, were conducted, one before (exam 1) and one after (exam 2) the implementation of COPT. Analysis of student performance in the examinations revealed that the students did better in exam 2 (P < 0.0001). Feedback from students indicated that this method was useful and challenging.

Influence of context and preferred learning environments: approaches to studying physiology

Tan CM, Thanaraj K

Med Educ, 1993 Mar;27(2):143-59.

PMID: 8336561

One hundred and twenty-eight medical students who had experienced a traditional-style preclinical curriculum completed three self-report questionnaires. Using factor analysis of students' responses this study explores interactions between study orientation, preferences for different kinds of learning environment, and evaluations of the physiology course. Such interactions can provide insight into the reasons why students fail to adopt effective learning strategies. Although many students had the intention to understand, they did not adopt a deep approach. Achievement motivation was strong, test anxiety high, and the course was perceived to be competitive. The meaning orientation merged with the achieving orientation; students were thus performance rather than task oriented. These students perceived the course to have been challenging, as did students within the reproducing orientation and who had 'surface' preferences. Students within the non-academic orientation had difficulty coping with the course. The findings suggest that conventional teaching and assessment methods are preventing students from developing appropriate criteria and internal standards for evaluating performance. An illusion of comprehension may prevent students from seeing the need to adopt more effective learning strategies and cause 'good' students with the ability to adopt a deep approach to abort the pursuit of deep understanding. Students' preferences and evaluations of teaching and assessment indicate that students within the different learning orientations have different educational needs. The implications for instruction and evaluation are discussed.

Fulltext Validating the effectiveness of Clinically Oriented Physiology Teaching (COPT) in undergraduate physiology curriculum

Abraham R, Ramnarayan K, Kamath A

BMC Med Educ, 2008 Jul 24;8:40.

PMID: 18652649 DOI: 10.1186/1472-6920-8-40

BACKGROUND: It has been proved that basic science knowledge learned in the context of a clinical case is actually better comprehended and more easily applied by medical students than basic science knowledge learned in isolation. The present study intended to validate the effectiveness of Clinically Oriented Physiology Teaching (COPT) in undergraduate medical curriculum at Melaka Manipal Medical College (Manipal Campus), Manipal, India.

METHODS: COPT was a teaching strategy wherein, students were taught physiology using cases and critical thinking questions. Three batches of undergraduate medical students (n = 434) served as the experimental groups to whom COPT was incorporated in the third block (teaching unit) of Physiology curriculum and one batch (n = 149) served as the control group to whom COPT was not incorporated. The experimental group of students were trained to answer clinically oriented questions whereas the control group of students were not trained. Both the group of students undertook a block exam which consisted of clinically oriented questions and recall questions, at the end of each block.

RESULTS: Comparison of pre-COPT and post-COPT essay exam scores of experimental group of students revealed that the post-COPT scores were significantly higher compared to the pre-COPT scores. Comparison of post-COPT essay exam scores of the experimental group and control group of students revealed that the experimental group of students performed better compared to the control group. Feedback from the students indicated that they preferred COPT to didactic lectures.

CONCLUSION: The study supports the fact that assessment and teaching patterns should fall in line with each other as proved by the better performance of the experimental group of students compared to the control group. COPT was also found to be a useful adjunct to didactic lectures in teaching physiology.

Fulltext Integrating an open-source course management system (Moodle) into the teaching of a first-year medical physiology course: a case study

Seluakumaran K, Jusof FF, Ismail R, Husain R

PMID: 22139773 DOI: 10.1152/advan.00008.2011

Educators in medical schools around the world are presently experimenting with innovative ways of using web-based learning to supplement the existing teaching and learning process. We have recently used a popular open-source course management system (CMS) called the modular object-oriented dynamic learning environment (Moodle) to construct an online site (DPhysiol) to facilitate our face-to-face teaching of physiology to a group of first-year students in the Bachelor of Medicine and Bachelor of Surgery program. The integration of the Moodle site into our teaching was assessed using online log activity, student examination marks, and feedback from students. The freely available Moodle platform was simple to use, helped to effectively deliver course materials, and has features that allowed cooperative learning. Students who used the CMS throughout their academic year and commented favorably regarding its use as a complement to the face-to-face classroom sessions. The group of students used the CMS obtained significantly higher scores in the final examination compared with the previous class that did not use the CMS. In addition, there was a significant correlation between student participation and performance in online quizzes and their final examination marks. However, students' overall online usage of the CMS did not correlate with their examination marks. We recommend Moodle as a useful tool for physiology educators who are interested in integrating web-based learning into their existing teaching curriculum.

It is quite difficult to teach complex topics like the physiology of vestibular apparatus to undergraduate students. Understanding the orientation and mode of stimulation of receptors in vestibular apparatus is also quite challenging for the students. As faculty we attempt to use innovative methods to teach physiology and enhance student learning.

Fulltext Student perceptions regarding the usefulness of explicit discussion of "Structure of the Observed Learning Outcome" taxonomy

Prakash ES, Narayan KA, Sethuraman KR

Adv Physiol Educ, 2010 Sep;34(3):145-9.

PMID: 20826769 DOI: 10.1152/advan.00026.2010

One method of grading responses of the descriptive type is by using Structure of Observed Learning Outcomes (SOLO) taxonomy. The basis of this study was the expectation that if students were oriented to SOLO taxonomy, it would provide them an opportunity to understand some of the factors that teachers consider while grading descriptive responses and possibly develop strategies to improve scores. We first sampled the perceptions of 68 second-year undergraduate medical students doing the Respiratory System course regarding the usefulness of explicit discussion of SOLO taxonomy. Subsequently, in a distinct cohort of 20 second-year medical students doing the Central Nervous System course, we sought to determine whether explicit illustration of SOLO taxonomy combined with some advice on better answering descriptive test questions (to an experimental group) resulted in better student scores in a continuous assessment test compared with providing advice for better answering test questions but without any reference to SOLO taxonomy (the control group). Student ratings of the clarity of the presentation on SOLO taxonomy appeared satisfactory to the authors, as was student understanding of our presentation. The majority of participants indicated that knowledge of SOLO taxonomy would help them study and prepare better answers for questions of the descriptive type. Although scores in the experimental and control group were comparable, this experience nonetheless provided us with the motivation to orient students to SOLO taxonomy early on in the medical program and further research factors that affect students' development of strategies based on knowledge of SOLO taxonomy.
