AbstractSimulations model concepts and phenomena. Several researchers have called for an intuitive and user-friendly simulation design to foster conceptual understanding of users. Simulations can also be used to promote mathematical thinking and problem-solving skills of students in various chemistry courses. An example of such use of simulations would be teaching reaction stoichiometry and underlying dimensional analysis for determining the quantity of reactants and products involved in a chemical reaction. In this paper, the author presents an innovative model of a guided-inquiry based simulation for promoting mathematical thinking in chemistry by incorporating mathematical thinking as a component of simulation design. The simulation was implemented in an introductory organic chemistry laboratory course in which a significant gain in pre- and post-test was observed for participating students.

New Knowledge

In our new education curriculum, it has been seen that it is no longer sufficient for students to learn only the achievements, unlike these gains, solution strategies that the student visualizes in his mind and designed by himself are also needed. Mathematical thinking, which is the process of obtaining new information completely different from the student's old knowledge and new knowledge, using it in the solution of the problem, and transforming that knowledge into new knowledge, has become extremely important. MEB asks students for deep mathematical thinking and problem solving skills in all questions they ask in the skill-based tests and student selection exam LGS. In this study, mathematical thinking and problem solving skills of middle school 7th grade students while solving problems will be examined. The research was applied to 241 students in 7 different secondary schools in the province of Bingöl in the Eastern Anatolia Region in the 2020-2021 academic year. In the study, it was investigated by quantitative and qualitative methods whether the mathematical thinking and problem solving skills of the students on rational numbers are related to gender, whether they had pre-school education and daily reading time. In the research, the SPSS 25 package program was used in the analysis of quantitative data, and in the analysis of qualitative data by examining the process steps in the answers from the students. As a result of the research, a statistically significant difference was found between male and female students, and this difference is in favor of female students. According to the findings obtained from the research, no statistically significant difference was found between the students who had and did not have pre-school education. Secondary school 7th grade students’ mathematical thinking and problem solving skills are related to their daily reading time. According to the results, students who read for an hour a day are more successful than students who read for fifteen minutes a day.

Objectives: The overall goal of the study was to foster self-directed learning, critical thinking and problem-solving skills in 1st-year medical students. Another goal was to create interest in learning by making it more interactive. As per the requirement of a competency-based medical education curriculum, we tried to use a novel teaching method called Flipped classroom method to meet our goals. Hence, the objectives of this study were: (1) To compare the effect of flipped classroom method and didactic lecture on students’ performance in the topics from renal physiology by MCQ test. (2) To obtain students’ perception about flipped classroom method in learning physiology. (3) To obtain teachers’ perception about flipped classroom method in teaching physiology. Materials and Methods: Flipped classroom method was introduced for teaching two topics in renal physiology for first MBBS students. This cross-over experimental study included 112 first M.B.B.S. students, after taking their informed consent and Ethics Committee permission. They were divided into two groups according to odd and even roll numbers. In the first part of the study, Group A (odd roll numbers) attended the didactic lecture on Renal Clearance (RC) and Group B (even roll numbers) attended the didactic lecture on Glomerular Filtration Rate (GFR). These topics were taught by two different teachers in two different classrooms. They were administered pre-test and post-test in the form of case-based MCQs which tests knowledge, critical thinking, and problem-solving skills on the topic. In the second part, two groups were swapped. Group A attended flipped class for G.F.R. and Group B attended flipped class for RC. They were again administered pre-test and post-test in the form of the same MCQ test. The teacher remained the same for the particular topic. For the flipped class, students came prepared with the topic. They were provided with resource materials of the allotted topic 1 week prior, in the form of pre-recorded lectures and videos. Students’ feedback in the form of a questionnaire and teachers’ feedback in the form of the interview was obtained. Marks obtained by students after didactic teaching and flipped classroom method teaching were compared by “Student’s t-test.” Results: The post-test score of students in the flipped class was significantly higher (P < 0.05) than the post-test score of students in didactic class. More than 85% of students agreed and strongly agreed that the flipped classroom method improved their learning in renal physiology and it increased their confidence in answering the topic in the final exam. Near about 50% of students liked the flipped class method because of its interactive nature and discussion which was based on the application of knowledge. The teachers were more satisfied by flipped classroom method of teaching. Conclusion: Flipped classroom method is an effective teaching-learning method in physiology when compared with a didactic lecture.
