Abstract

Mathematical critical thinking skills have so far shown unsatisfactory results, so media or learning resources such as worksheets are needed to complete them. In addition, concepts of scientific learning such as Niteni, Nirokke, and Nambahi activities have not provided opportunities for students to think critically. For this reason, this study aims to obtain valid and practical relations and function worksheets based on tri-n. The research stages used are defining, designing, and developing. These three stages are part of the development research with 4D. At the defining stage, data collection techniques use documentation to make the data analysis qualitative. At the design stage, data collection techniques use observation to make the data analysis qualitative descriptive. In the developing stage, the data collection technique uses a questionnaire, so the data analysis is quantitative. The results showed that the relations and function worksheets based on Tri-N had a V-Aiken index of more than 0.83, and some students responded well to this worksheet. Apart from that, the mathematics material in this Student Worksheet uses the Tri-N stages, namely Niteni, Nirokke, and Nambahi. Based on this, it can be concluded that the Tri-N-based Student Worksheet on Relations and Functions is a valid and practical result of development.

Abstract

Researchers have widely researched the effects of teaching props, and most concluded that, statistically, there is an effect on problem-solving ability. However, how significant is the effect on problem-solving ability, and whether their research results are parallel to other research they have yet to do? So, the reliability of research related to teaching props still needs to be considered. This research aims to analyze the results that examine teaching props on problem-solving abilities. The method used in this research is meta-analysis. This research was carried out through meta-analysis stages, namely determining inclusion criteria, collecting data and coding variables, statistical analysis by determining the effect size, and making conclusions from the data obtained. Data collection was carried out by collecting data from research conducted from 2018 to 2023 on the Google Scholar database. This data collection obtained twenty-six (26) studies that met the inclusion criteria for extraction from research and development, experimental, and quasi-experimental. Effect size measures the effect of teaching props on students' problem-solving abilities. Based on these calculations, an effect size value of 2.449. This research indicates a significant and positive influence between teaching props and students' problem-solving skills, especially in mathematical learning. Therefore, it is necessary to develop teaching props to improve mathematical problem-solving skills.

Abstract

This research investigates the effectiveness of problem-based mathematics learning through blended learning with the help of Edmodo and GeoGebra in improving problem-solving skills in mathematics learning. The primary motivation of this research is to develop a learning approach that can overcome challenges in solving mathematical problems. The method used in this study used a quantitative approach, and a quasi-experimental pre-test and post-test control group design was applied. This study involved 72 students in two semesters from a university in Banten, Indonesia, with 36 students in the experimental class (11 male and 25 female) and 36 in the control class (10 male and 26 female). Data was collected through problem-solving tests before and after the learning intervention—data analysis using paired t-tests and independent t-tests. The group using Edmodo-GeoGebra (BL-UEG) and the group Edmodo without GeoGebra (BL-EWG) experienced an increase in the moderate category. In conclusion, problem-based mathematics learning through blended learning with the help of Edmodo and GeoGebra can be an effective alternative learning model for improving students’ problem-solving abilities in mathematics. Therefore, this approach deserves further exploration in learning settings.
