Challenges in understanding meiosis: fostering metaconceptual awareness among university biology students

In this study, firstly, university biology students’ conceptual understanding and potential misconceptions concerning meiosis were studied. Secondly, an easily applicable drawing task was used to foster students’ metaconceptual awareness which would help them to reach conceptual change. A quasi-experimental design with a non-equivalent control group was conducted. The students (N = 82) were divided into experimental and control groups. The control groups attended traditional teaching, i.e. lectures with practicals, whilst the experimental groups had an additional activating task before practicals. In the activating task, the students drew the selected phases of meiosis and marked given concepts of meiosis in the drawing. The drawings were scored and the solutions were discussed in detail with the students. After the activating task, the traditional practicals were held for both groups. After a week, both experimental and control groups were given the same task. The results show that students in the experimental group understood meiosis significantly better than the control group, who had more misconceptions after the instruction compared to the experimental group. Thus, fostering students’ metaconceptual awareness is crucial and relatively easy to apply, also in higher education.</p

Conceptual change challenges in medicine during professional development

This study investigates professional development during medical studies from a conceptual change perspective. Medical students' conceptual understanding and clinical reasoning concerning the central cardiovascular system were investigated during the first three years of study. Professional development was inspected from the perspectives of biomedical knowledge, clinical knowledge and skills needed to solve a patient case. Biomedical misconceptions regarding false beliefs and mental models were detected. Students with misconceptions were more likely to give lower level answers in clinical application tasks and to make inaccurate diagnoses compared to those students who had accurate conceptual understanding. Based on the results, pedagogical suggestions are discussed

Medical students' biomedical and clinical knowledge: Combining longitudinal design, eye tracking and comparison with residents' performance

This study combines longitudinal and individual process-level analyses to investigate medical students' biomedical knowledge and how they generate a diagnosis for a patient case text. The diagnostic processes were investigated using the eye-tracking method, and students' processes were compared with those of residents. The results showed that students differed in their diagnostic performance in the beginning of the clinical phase. Of the students who had biomedical misconceptions in the preclinical phase, 69% ended up with an incorrect diagnosis, while 60% of students with accurate biomedical knowledge made a correct diagnosis. The processing of a patient case text was faster among better achieving students and residents. Furthermore, residents' illness-script activation could be seen from their eye-movement data as a relatively longer reading time regarding the sentence that concerned the enabling condition of the case. Based on the results of the study, pedagogical suggestions are discussed. (C) 2017 Elsevier Ltd. All rights reserved
