Abstract

This research aims to determine whether there is an influence of the exploration, elaboration and confirmation (EEK) model in learning straight line equations on the learning outcomes of class VIII students at SMPN 1 Jonggat in the 2023/2024 academic year. This Quasi Experimental Research was designed using a post-test only non-equivalent control group design. The population in this study were all class VIII students at SMPN 1 Jonggat for the 2023/2024 academic year. Two classes were chosen as samples, namely class VIII B as the experimental class and class VIII A as the control class. The instruments used in this research were student learning outcomes tests (post-test), RPP, LKPD and observation sheets. The analysis technique used is parametric statistics with the result t_count = 5.93 > t_(table ) = 2.00 which shows that there is a difference in the average learning outcomes of the experimental group and the control group. Where the average learning outcomes of the experimental group are higher than the average learning outcomes of the control group. The effect size test results obtained a d value of 1.5 with high criteria. So it can be concluded that there is a high influence in the use of exploration, elaboration and confirmation models on the learning outcomes of class VIII students at SMPN 1 Jonggat.

Abstract

Limited access to printed materials, lack of interaction, and lack of multimedia-based learning media are significant problems, especially in remote areas such as NTB. In addition, the situation is further complicated by the limitations of infrastructure, internet connections, and teachers' technological capabilities. The purpose of this study is to create a web-based Learning Resource Center (PSB) that utilizes technology to support learning and offer interactive teaching materials. Needs analysis, PSB structure development, guideline preparation, and validation and usability test are all methods used to conduct this study. The inability of technology, the limitations of infrastructure, and the effects of print media on the environment are the main problems identified. Interactive teaching materials, teacher training, wider access to learning materials, and web-based multimedia are some of the solutions that come to mind. The results show that the web-based PSB can function as a learning resource center and support the development of technology-based teaching materials, learning systems, and multimedia. This PSB also provides facilities such as multimedia labs, digital libraries, and access to interactive teaching materials, which improve the quality of learning. So, web-based PSBs help support technology learning, overcome limited access to teaching materials, and improve the quality and efficiency of education, especially in areas with limited infrastructure.

Abstract

This research aims to determine the relationship between the perceptions of class VIII students at SMPN 13 Mataram regarding mathematics and their learning persistence, partially with learning outcomes, and the influence of both simultaneously on learning outcomes. The type of research used is ex-post facto research with a quantitative approach. The research instruments used were perception questionnaires, study persistence questionnaires, and tests on SPLDV material. The research sampling technique used simple random sampling, using 30 class VIII students at SMPN 13 Mataram as samples. Before taking samples, a homogeneity test was carried out on the population, it was found that the population was homogeneous. The results of this study show that there is a relationship between perceptions and learning outcomes, but with a relatively low correlation. Likewise, between persistence and learning outcomes, there is a relationship with a correlation that is classified as very low. The correlation test results are 0.253 and 0.162, respectively. However, simultaneously, perceptions and learning outcomes have a significant influence on learning outcomes. This is shown by Fcount (3.682) > Ftable (3.35). The regression equation obtained is Ŷ = 0.8 + 0.6X1 + 0.1X2.

Abstract

This research is motivated by the low numeracy skills of students in Indonesia, particularly in mathematics, with only 28% achieving proficiency at Level 2, far below the OECD average. The research problem includes questions about the effectiveness of Interactive Mathematics Learning Media (GeoGebra and Website) in improving students' numeracy skills in Geometry Transformation material. The aim of the research is to evaluate the effectiveness of this learning media, and the results are expected to provide an alternative for teachers in enhancing students' numeracy skills, which is crucial in addressing the wide educational quality gap in Indonesia compared to other countries, especially in terms of students' numeracy abilities. This research is also expected to provide recommendations to support the improvement of mathematics education quality at the junior high school level. This study is a case study involving 2 teachers and 8 students. The interactive mathematics learning media, integrating GeoGebra and the website, is effective in improving students' numeracy skills in geometry transformation material. The effectiveness of the interactive mathematics learning media can be seen through sufficient activities that allow students to explore the properties of translation, rotation, reflection, congruence, and dilation. Students' understanding of these properties in geometry transformation is followed by activities in solving geometry-related problems. Finally, conclusions are drawn on techniques for solving problems related to geometry transformation material.

Abstract

This study aims to determine the effect of the cooperative learning model, specifically the Teams Games Tournaments (TGT) type assisted by Quizizz, on the mathematical literacy skills of 11th-grade students at MAN 1 Mataram in the academic year 2024/2025. This research is a quasi-experimental study using a posttest-only control group design. The population consisted of three 11th-grade science classes with a total of 118 students, and the sample included two classes: XI IPA 1 as the control group, which received direct instruction, and XI IPA 2 as the experimental group, which received the TGT model assisted by Quizizz. The sampling technique used was cluster random sampling. Data were collected through a mathematical literacy skills test administered after the intervention and were analyzed using normality and homogeneity tests. Based on the results, a non-parametric test chi-square test was employed along with the calculation of the effect size. The findings showed a difference in the average scores between the control group (49) and the experimental group (78), indicating the influence of the TGT model assisted by Quizizz on students' mathematical literacy. The effect size value of d = 0.465 falls within the medium category, suggesting a moderate impact. Therefore, the TGT cooperative learning model assisted by Quizizz contributes positively to enhancing students' mathematical literacy, particularly in function-related topics such as trigonometry, logarithms, and algebra. Future studies are recommended to further explore the implementation of this model across different educational levels, subject matter, and broader learning contexts.
