Development of Statistical Literacy-Based e-Modules for Pre-service Teachers Learning Statistics
Get PDFThe concepts of statistics could be hard to understand by students without grasping the problem context. Using an easy-to-understand context or context that is close to the students in statistics learning materials could help students’ understanding of the statistical concept. This research and development study was conducted to develop an e-module based on statistical literacy for pre-service teachers learning statistics. The topics of e-module developed consisted of topics related to the introduction to statistics and data presentation while using some Islamic contexts and values that are close to the participants. The research was conducted in two stages: the developmental stage and the experimental stage. The developmental stage included problem analysis and literature studies, development of the initial e-module, validation and revision of the e-module. The experimental stage included testing the effectiveness of the e-module for 164 pre-service teachers from 7 study programs of IAIN Lhokseumawe, Aceh. The quantitative data from this experimental phase was analyzed using ANCOVA by controlling prior knowledge in statistics and digital literacy skills to evaluate the influence of the e-module on participants’ performance in statistics. The qualitative data of the interview transcripts was analyzed using content analysis. The statistical analysis results showed no significant difference in statistical performance between students using the e-module and students using conventional learning texts. However, from the interviews, we found that, in general, students acknowledged that the e-module used was interesting and that it facilitated their understanding of statistical concepts. However, they encountered obstacles when accessing the e-module due to the weak and unstable internet connection. Suggestions were provided for future research direction to ensure the effectiveness of using the developed e-module.

Skepticism of Students Participating in National Science Olympiad in Solving Geometry Problems across Gender Differences
Get PDFThis study is a qualitative descriptive study that aims to determine and describe the skeptical attitudes of female and male students involved in solving logical problems in geometry material and identify differences in problem-solving strategies between them. The researcher refers to the skeptical stages developed by Berta (2024) which consist of two stages, namely skepticism confirming and skepticism dismissing. This study involved two tenth grader female students and two eleventh grade male students participating in national science olympiad from MAN 1 Jembrana, Indonesia. The data analysis techniques in this study were data reduction, data presentation, and drawing conclusions or verification. Data collection used in this study was in the form of Logical problems-III questions, interviews and the think aloud method. The findings of this study indicate that there are significant differences between the ways male and female national science olympiad students deal with illogical questions. Male national science olympiad students tend to show higher skepticism, characterized by a tendency to dismiss work and calculations without alternative solutions. In contrast, female national science olympiad students tend to use a more careful and systematic approach to solving problems and are more careful in questioning the information provided and getting alternative solutions that result in more systematic solutions. Although this sometimes causes confusion or doubt that can slow down the decision-making process but can get calculated results. This study concludes that gender differences in skepticism affect students' approaches to solving Logical problems-III which emphasizes the importance of adaptive learning strategies to support the development of critical and logical thinking skills in both groups of students. Keywords: geometri,logical problems-iii, skeptis. DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp496-51
