Abstract

This research focus is on the ability to solve word problems on mixed arithmetic operations. The research objective is to analyze errors in solving word problems in mixed arithmetic operations material. Furthermore, this research approach was qualitative research. The data sources were 10 fourth-grade students and a fourth-grade teacher at State Elementary School 1 Sulursari; teachers were chosen because of their role in learning. Data collection procedures consisted of tests and interviews. The research showed that fourth-grade students experienced errors in solving word problems on mixed arithmetic operations, including reading, transformation, process skills, and final answer writing errors. The suggestions conveyed to students when learning should pay attention to the teacher when explaining the material well so that they can ask the teacher when they don't understand the material. Multiply practice questions so that you know better when working on questions; you should carefully not need to rush.

Abstract

This study aims to determine the ability of mathematical representation of students in geometry material after learning with the help of GeoGebra. This research is motivated by students' difficulty in interpreting geometric shapes. This research is qualitative research with a descriptive approach. The subjects in this study were 3 (three) class XII students who had obtained three-dimensional material with the help of GeoGebra applications. Researchers carry out the data collection process by providing mathematical representation ability test questions, conducting interviews, and taking documentation. The data obtained in this study were analyzed using specialized triangulation-checking techniques. Based on the results of data analysis and the effects of interviews with all research subjects, it can be concluded that learning geometry with the help of GeoGebra applications can improve mathematical representation capabilities. Three mathematical representation abilities, namely visual representation, equation or expression, and written words or texts, are possessed by students after learning geometry with the help of GeoGebra applications.

Abstract

Critical thinking ability is one of the higher orders thinking skills that is highly needed in 21st-century learning. One learning model that can develop and enhance students' necessary thinking skills, especially in learning mathematics, is the Discovery Learning model. Using video media in learning can motivate and assist students in learning mathematics. This study aimed to determine the increase in students' mathematical critical thinking skills through the Discovery Learning model helped by teaching videos. The research method used is quasi-experimental. The samples in this study were students at class VII Bandung National Middle School. The sample was selected by purposive sampling technique. This research shows that students who get the Discovery Learning model assisted by video-assisted learning have a higher mathematical critical thinking ability than those who get conventional models.

Abstract

This research aims to reveal the results of curriculum evaluations that refer to the Indonesian National Qualifications Framework. The assessment form uses the context, input, process, and product model, but this paper will only examine the product section analysis. This research is evaluation research with a qualitative approach. Data collection techniques used observation, questionnaires, and interviews, then validated using triangulation, namely methods, sources, and expert group discussion forums. This study was analyzed using the Miles and Huberman model, including data reduction, presentation, and conclusions. The results of the product section evaluation are as follows 1). The learning achievement of 3 aspects successfully achieved cognitive by 75%, practical at 75.51%, and psychomotor at 74.12%. 2). 99% of students have a Semester Grade Point Average that meets the criteria, and 3). 85.8% of graduates managed to get jobs according to the curriculum.

Abstract

This study aims to investigate how elementary school students' computational thinking skills in learning 3D Geometry. The research method used was quasi-experimental with a pure post-test design of the 31 elementary school students selected using a purposive technique- sampling. Constructive, content and empirically validated calculus tests served as research tools. According to the results of this study, the computational thinking skills of elementary school students were greatly improved by learning from 3D-Geometry problems, and the average score was ranked high at 67.48 points. In this way, learning based on 3D-Geometry problems can be applied to the development of computational thinking skills in elementary school students.

Abstract

Learning mathematics in Indonesia has not had a significant effect on improving students' creative thinking abilities. It is hoped that the Model Elicting Activities (MEAs) trial can be an alternative solution to this problem. So the first objective of the study was to find out whether MEAs learning had a better effect on improving students' creative thinking skills compared to conventional learning models. The second research objective is to determine the level of effectiveness of implementing the MEAs learning itself. The research objectives were achieved using a quasi-experimental study method with the pretest-post-test non-equivalent group design. The research subjects were class VII students of SMP L'Pina, East Jakarta, consisting of 25 students from the experimental class and 25 students from the control class. The research instrument is a test of creative thinking skills. Data on test results were analyzed using the t-test. The results of the data analysis concluded that: (1) MEAs learning has a better influence on students' creative thinking abilities than conventional learning models, and; (2) MEAs learning can significantly improve students' creative thinking skills.
