Authors:Oğuzhan Bahadır, Hande Türkmençalıkoğlu, Ebenezer Bonyah Pages: 250 - 260 Abstract: The entropy formula, created by Claude E. Shannon using probability calculations, is an essential and objective measurement method used in multi-criteria decision-making. The purpose this study was to evaluate the problems experienced by mathematics teachers during the Covid-19 and the degree of importance of these problems were determined. Expert opinions were used to identify the problems. In the study, the ‘Entropy’ method was used to determine the degree of importance of the problems. After determining the problems, a questionnaire was applied to 22 teachers working in different geographical regions of Turkey and with different service lengths. According to the entropy results, it has been determined that the most critical problem faced by mathematics teachers in the distance education process is the ‘communication problem’ between students and teachers. In conclusion, mathematics teachers must find the right learning method to overcome communication problems so that in the future, distance learning will not experience obstacles.

Authors:Komarudin Komarudin, Yuberti Yuberti, Dona Dinda Pratiwi, Muhamad Afandi, Rani Wardani, Laila Puspita Pages: 330 - 340 Abstract: A low understanding of mathematical concepts can affect a student's learning process. In overcoming this problem, teachers must pay attention to students’ self-efficacy. This quasi-experimental study aimed to determine the effect of the RME-based Krulik-Rudnick Heuristics learning model on understanding mathematical concepts regarding students' self-efficacy. The samples were obtained using the cluster random sampling technique. The data collection technique used was a test of description questions. Hypothesis testing was performed using two-way ANOVA. The research found that Fa was F(0.05;1.45); therefore, H0A was rejected. Furthermore, Fb was lower than F(0.05;2;45), so H0B was accepted, and Fab was lower than F (0.05;2.45), so H0AB was accepted. It can be concluded that there was an effect of the learning model used on understanding mathematical concepts, there was no effect of self-efficacy (high, medium, and low) on mathematical concept understanding, and there was no interaction between learning models and self-efficacy (high, medium and low) on students' mathematical concepts understanding. It is recommended that further researchers apply RME-based Krulik-Rudnick Heuristics to other learning materials. PubDate: 2022-11-29 DOI: 10.24042/ijsme.v5i3.13178 Issue No:Vol. 5, No. 3 (2022)
