Abstract

Based on research, most students have difficulty understanding the principles and operations of numbers. Therefore, the writer was moved to do this research. This research is classified as a qualitative descriptive research that aims to describe students' difficulties when working on problems in the Numbers material. The research subjects were 15 students of class VII B SMP Pasundan 1 Cimahi. The data processing technique in this study uses the formula proposed by Arikunto. From the results of the analysis, the first indicator 73% is classified as sufficient category. The second indicator, namely 55%, is in the poor category. The third indicator reached 73% in the sufficient category. The 4th indicator reached 82% in the good category. The 5th indicator reached 89% in the very good category. From the description above, it is clear that students have the most difficulty in working on number problems, namely that students are still difficult in working on questions with complicated operations. The factors behind these difficulties are: (1) Lack of understanding of the concept of work on number operations, (2) Teacher discussion that is not clear, (3) Insufficient use of learning media.

Abstract

The Praktisi Mengajar program is thought to have an important role in improving the quality of student learning in tertiary institutions. Universities invite practitioners as guest lecturers for certain courses with the hope of providing practical experience to students so they are better prepared to face the world of work after graduation. However, there are still many unanswered questions regarding the effectiveness of Praktisi Mengajar in improving course outcomes. The purpose of this study is to investigate how the Praktisi Mengajar program effects course outcomes and to describe student perceptions of the program. The study's findings indicate that the Praktisi Mengajar Program has an impact on KPMI course outcomes, and a description of students' positive perceptions toward the program was collected.

Abstract

Computational thinking is a person's ability to present problems and their solutions through certain algorithms so that the algorithms can be reused by other people and computers to solve the same problems. This study aims to comprehensively examine students' computational thinking skill reviewed from different self-efficacy levels. This research is descriptive qualitative research. The subjects in this study were 3 seventh grade students of Bumi Cendekia Junior High School in the 2022/2023 school year who were selected based on low, medium, and high self-efficacy levels. The instruments used were test, questionnaire, and interview. Data analysis was carried out using qualitative data analysis which included data reduction, data presentation, verification, and conclusion.  The results showed that students with low self-efficacy level were only able to fulfill 2 indicators of computational thinking ability, students with moderate self-efficacy level fulfilled 3 indicators of computational thinking ability. Meanwhile, students with high self-efficacy level have excellent computational thinking ability by being able to fulfill 4 indicators of computational thinking ability.

Abstract

This research aims to develop LKPD based on Problem Based Instruction (PBI) for students' mathematical problem solving abilities. This type of research is the research and development (R&D) ADDIE development model. Validity, practicality and effectiveness are the three kinds of instruments to be analyzed. The research subjects for the validity test are lecturers as media experts and teachers as material experts. While the practical and effectiveness test subjects were thirty eighth graders. The research instruments used are questionnaires and tests. The data analysis techniques used are qualitative data analysis from validator comments and suggestions and quantitative data analysis in the form of scoring the percentage of validity, practicality and effectiveness of LKPD. Research conclusions: (1) Problem Based Instruction (PBI)-based LKPD on opportunity material meets the criteria, is very valid, very practical and very effective and can be used in the student learning process (2) Student learning outcomes after participating in learning using Problem Based Instruction (PBI)-based LKPD have met the expected problem-solving ability indicators.

Abstract

This research investigates the involvement and ability of junior high school students in solving mathematical problems by incorporating GeoGebra in the Numbered Head Together (NHT) approach. A dynamic mathematics application called GeoGebra and (NHT) is thought to offer improved problem solving and active learning. This research used a quasi-experimental with an equivalent control group design for State Middle School students in Cilegon City. Questionnaires and tests of mathematical problem solving abilities are the research instruments used. The analysis techniques used was prerequisite tests (normality test and homogeneity test), hypothesis testing (independent t test) and percentage of learning activity questionnaires. The results of data analysis show statistically significant differences between the control and experimental groups using GeoGebra on NHT learning and student engagement. The research recommendation from the research results is to encourage teachers to integrate dynamic software in the preparation and implementation of teaching using GeoGebra.

Abstract

Many academics and practitioners do research and teaching to develop early childhood numeracy skills by involving various learning elements such as teaching methods and learning media. The National Council of Teachers of Mathematics (NCTM) is the largest mathematics teacher organization in the world to explain mathematics education into two standards, namely content standards and process standards. Therefore, this research aims to examine numeracy activities against NCTM mathematics education standards. To discuss this objective, the research method used is a Systematic Literature Review (SLR) of 21 research articles which can be accessed on the Google Scholar website for the year 2022-2023. After the data was obtained, the data was analyzed using thematic data analysis. The research results show that learning elements which include teaching methods and learning media to introduce and develop numeracy skills in early childhood can be used to introduce and develop mathematical abilities in the NCTM mathematics education content standards, namely algebra, geometry, measurement data analysis, and probability.
