Abstract

Lack of knowledge is one of the factors that causes individuals to commit violence, namely bullying. Bullying is a repeated negative behavior that intends to cause displeasure or hurt by another person, either one or several people, directly against someone who is unable to fight it. According to Yahya and Ahmad (2005) in (Nathania et al., 2022) on a 2004 survey conducted by the Japanese Ministry of Education, it was stated that there were 24,898 cases of bullying of these cases occurring in private universities (PTS). The purpose of this literature review is to analyze the results of research analysis related to the level of knowledge of PGSD students at Muhammadiyah University of North Sumatra about bullying behavior. The research method used is a quantitative method.

Abstract

The problem in this study is that the Learning media is quite limited and less interesting. The difficulty of teachers controlling the online learning process during the pandemic. The purpose of this research is to develop a science practicum e-module with a valid and practical Android-based discovery learning approach. This research is research and development with the Borg and Gall model. The 5 stages of this research are preliminary research and analysis, developing initial products, expert validation and revision, small-scale field trials and product revisions, and large-scale field trials. The research instrument used interviews and media validation questionnaire sheets, material validation , and user validation. This study was conducted on a small scale where the subjects were class teachers and 6 students of Grade IV SD Muhammadiyah 1 Palu. Based on the results of data analysis obtained material validity values of 23, 12, 9, 11, and 12 with a very strong Category. user (student) satisfaction respectively 91.7, 88.3, ​​96.7, and 86.7 7, and user (teacher) satisfaction of 90, 70, 100, and 100 with very good category. So it can be concluded that the Android-based E-module discon (E-module DISROID) developed in the criteria is very valid and practical. So that this module can be used in science learning, especially for practicum activities in Grade IV of elementary school.

Abstract

The 2013 curriculum is oriented towards producing quality students who are rooted in the nation's culture and are developed based on a global perspective. The process of making alcoholic beverages, is one example of integration elements of natural science and local wisdom as a form of cultural preservation. However the school still have lack of references and sensitivity to efforts to explore the local wisdom activities of the community, especially in the alcohol-making process.  This research aims to analyse the ethno science study on the alcohol-making process in natural science learning in elementary schools. This study used a qualitative approach and is included in the ethno science research type. The data source in this study was determined through a purposive sampling technique, with two alcohol makers as the subjects. These research’s objects consisted of the alcohol-making process and ethnoscience studies in alcohol making process in natural science learning in elementary schools, which were obtained through interviews, observations, and documentation. The analysis technique employed was the Miles and Huberman model (data reduction, presentation, and verification). The results uncovered that the alcohol-making process it is associated with natural science learning materials in elementary schools, it relates to phase transition, convection (heat transfer), conductors, and energy sources.

Abstract

This study aimed to determine the effect of the “number pouch” media on the mathematical critical thinking skills of first-grade students at SD Muhammadiyah 12 Medan. The research population comprised all first-grade students, with one class designated as the experimental group and another as the control group. This quantitative research employed a Pre-Test Post-Test Control Group Design. The sample consisted of 40 students, divided into two classes: 22 students in the experimental group and 18 in the control group. Data analysis was conducted using SPSS 23. The findings indicated that the “number bag” media significantly enhanced students' critical thinking abilities in mathematics, particularly in performing vertical addition operations. The research instrument was a test, and data analysis techniques included validity tests, reliability tests, normality tests, homogeneity tests, N-gain tests, and hypothesis testing. Results from the independent t-test analysis showed a significant value (sig. 2-tailed) of 0.000, which is less than 0.05, leading to the acceptance of the alternative hypothesis (Ha) and rejection of the null hypothesis (H0). This outcome suggests that the “bag of numbers” media positively affects the critical thinking skills of first-grade students at SD Muhammadiyah 12 Medan. Students who received instruction using the “bag of numbers” media achieved higher average scores compared to those who did not use the media, indicating that the independent variable (solution) employed in the study influenced the dependent variable (problem).
