Measuring attitudes towards biology major and non-major: Effect of students' gender, group composition, and learning environment

This study examined the effect of collaborative learning (CL) versus traditional lecture-based learning (TL) pedagogies and gender group composition in effecting positive or negative attitudes of biology major and nonmajor men and women students. The experimental research method was administered in experimental and control groups to test the hypotheses. Students’ attitudes refer to their positive or negative feelings and inclinations to learn biology. A nine-factor attitude scale was administered in (1) single-gender nonmajor biology, (2) mixed-gender nonmajor biology, (3) single-gender major biology, and (4) mixed-gender biology major groups. Men (221) and women (219) were randomly assigned into single and mixed-gender classes without groups and single-gender groups (4M) or (4W) and mix-gender (2M+2W) groups. In CL nonmajor and major single-gender groups, women demonstrated significantly higher positive attitudes than men. In contrast, men’s attitudes were significantly improved in mixed-gender CL groups for major and nonmajor sections, and the effect size was larger in mix-gender classes. Women feel less anxious in single-gender groups but more anxious in mixed-gender groups. In mixed-gender groups, men’s self-efficacy, general interest, and motivation enhanced significantly; overall, men experienced greater satisfaction and triggered their desire to collaborate better, affecting all nine attitudinal factors. There was an interaction effect demonstrating the teaching pedagogy’s impact on improving students’ attitudes toward biology; students’ gender and gender-specific group composition have been the most influential factor for nonmajor students. These findings suggest that there is a need for developing gender-specific and context-specific learning pedagogies, and instructors carefully select gender grouping in teaching undergraduate science subjects.

Emotional Performance of a Low-Cost Eco-Friendly Project Based Learning Methodology for Science Education: An Approach in Prospective Teachers

Enhancing the emotional dimension of prospective teachers in science subjects—which has become increasingly important in recent decades—is a responsibility of higher education institutions. The implementation of active methodologies has the potential to modify the traditional student-teacher roles that are encouraged by the educational policies implemented in the Bologna Process. Simultaneously, it is possible to promote knowledge of sustainability, as well as the attitudes and behaviors required by UNESCO. The main aim of this work is to describe a project-based learning methodology with a transversal sustainability approach (low-cost and eco-friendly) and to introduce this as a potential resource for the emotional and cognitive improvement of 19 prospective primary teachers enrolled in scientific subjects. This is a qualitative study in the context of a research line focused on higher education for sustainable development. A questionnaire was designed and filled in by students at two different stages, before and after implementation of the activity. The initial feedback from students was surprisingly enthusiastic due to the fact that they were working with rockets, despite this not being considered a common emotion expressed by students in science lessons. The results show the emotional improvement of prospective teachers after implementation of the activity. It is concluded that a good science education, with implementation of sustainable approaches is necessary during the training of teachers, taking into account their emotional dimensions and social repercussions as a consequence of future transmission.

Update on research and application of problem-based learning in medical science education

Problem-based learning (PBL) is a unique form of pedagogy dedicated to developing students' self-learning and clinical practice skills. After several decades of development, although applications vary, PBL has been recognized all over the world and implemented by many medical schools. This review summarizes and updates the application and study of PBL in medical education through the literature published between 1993 and early 2017. It focuses on understanding real medical PBL courses and ways to improve PBL to achieve better learning outcomes. PBL aims to develop lifelong skills to solve practical problems rather than limiting learning to theoretical knowledge. To achieve this goal, strict and reasonable procedures need to be designed and implemented. Rigorous monitoring and timely feedback and evaluation are indispensable to constant improvements and perfecting of the process. © 2017 by The International Union of Biochemistry and Molecular Biology, 46(2):186-194, 2018.
