Abstract

The aim of this study is to evaluate the enhancement of mathematical problem-solving abilities among Grade VII Junior High School students using two different instructional models: the Visual Basic for Applications Excel (VBA) Assisted Problem-Based Learning Model and the scientific learning model. The research employs an experimental approach with a pretest-posttest control group design involving two groups: an experimental class and a control class. The entire 7th-grade population of SMP Negeri 3 Lembang participated in the study, with Class VII-D serving as the experimental group and Class VII-E as the control group. Data on mathematical problem-solving abilities were collected through pretest and posttest assessments. Data analysis was conducted using Microsoft Excel and SPSS 29. The findings indicate that students in the experimental group, who were taught using the Problem-Based Learning Model assisted by Visual Basic for Applications Excel (VBA), demonstrated greater improvement in their mathematical problem-solving skills compared to those taught using the scientific learning model.

Abstract

Mathematicals communication ability is one of essential mathematical abilities that every person, who learns mathematics, needs to have. However, many facts found in many studies has shown us that students’ achievements on this ability are still low. Factors that may cause it spread from teacher factors, tools, approaches, learning media to students themselves. To overcome these issues, many efforts are made to select and implement learning approaches that can improve students' mathematical communication ability as well as their activities in instructional process. Thus, the purpose of this study is to examine whether the implementation of GeoGebra-assisted discovery learning approach is effective in improving vocational school students' mathematicals communication ability or not. This quasi experimental research design involved 60 students of Gema Karya Bahana Vocational School as samples. The samples were divided into two groups in which 30 students of Accounting-1 class as the experimental group and 30 students of Accounting-2 as the control group. The data collected through a description test consisted of 3 questions on a linear program. The data collected through the test, both in pre-test and post-test, then analyzed using inferential statistics. The results of this analysis showed that the implementation of the discovery Learning approach assisted by GeoGebra was effective in improving vocational school students' mathematicals communication ability. Thus,  the discovery learning approach assisted by GeoGebra can be implemented on instructional processes as one of  instructional approach alternatives.

Abstract

In order to enhance students' mathematical problem-solving skills, this study looks at how teaching materials are developed using the Discovery Learning model. Since every student nowadays needs to be able to think critically, the study specifically looks at the process and outcomes. development, viability testing, feedback from students, and improving mathematical problem-solving skills. This kind of research makes use of the Research and Development (R&D) or Research-based Development research method, which is a way to create a specific product and use a model to test the product's viability. Students in class VII at MTs Al Bidayah West Bandung Regency served as the research sample for S. Thiagarajan's 4D (Define, Design, Develop, and Disseminate) study. The process and outcomes of creating educational materials lead to the conclusion that the materials, when viewed from the various stages, follow the procedures or methods outlined in 4D. Based on students' responses, which were 68.4% and 70.2% in the good category, the viability of teaching materials made possible by the Photoshop program can be concluded, along with the students' improved problem-solving skills. If this teaching material is used in a classroom setting, it is imperative that the necessary facilities be set up ahead of time because learning with it requires sufficient facilities. There are tasks and content in this teaching resource that need to be altered. so that students' learning experiences are not dull and monotonous.

Abstract

This study aims to study and analyze the improvement of mathematical problem-solving skills in students who use the Contextual Teaching and Learning approach. This research is a type of quasi-experimental research with the population of grade VIII students at SMP Negeri 2 Batujajar and the sample of this study is students of grades VIII B and VIII C. The data collection instrument in this study uses mathematical problem-solving ability test questions in the form of descriptions of five questions. Quantitative data processing used the analysis of 2 dependent samples with a normality test and continued with a paired t-test. The results of this study are: Improvement of mathematical problem-solving ability of junior high school students in grade VIII whose learning uses the Contextual Teaching and Learning approach is better than those who use ordinary learning in Pythagorean Theorem material because in their learning they use all the characteristics of CTL, so that they can train students to solve a problem presented.
