Abstract

This study aims to develop storybooks on grade II mathematics material, describe the validity of the products resulting from the development of storybooks, and describe the practicality of the products produced. This research method is research and development (reseach and development). Researchers use R&D procedures according to ADDIE (Analyze, Design, Development, Implementation, and Evaluation). Data collection techniques were carried out through observation, interviews, and questionnaires. The subjects of this study were second grade students of Gandok State Elementary School. The data analysis technique used was data collection through questionnaires. The result of the research is a development product in the form of storybooks on mathematics learning materials for addition and subtraction of numerical numbers in grade II. On valid criteria, the results of the material expert validation obtained a percentage of 85%, while for the construction expert obtained a percentage of 97%. This the storybook developed is on very valid criteria. On practical criteria, both class teacher and learner responses get a percentage result of 100% or are on very practical criteria. From the responses of teachers and students, it can be stated that the storybooks developed get very practical criteria. Based on this, the storybook developed can be declared valid and practical. This storybook is expected to be an additional book in the process of learning grade II mathematics and increasing students' understanding of addition and subtraction counting operation.

Abstract

This study aims to describe students' mistakes in solving rectangular problems based on their cognitive development. This research is a descriptive qualitative study with 4 research’s subjects taken based on purposive sampling. Data collection techniques use tests, namely Test of Logical Operations and Problem-solving Tests. Data analysis techniques include reduction, presentation, and data verification. The results of the study show that mistakes that are often made by students are less complete in writing what is known and asked about the problem. At the stage of devising a plan, students are wrong in determining the formula, the complete steps to be used, and do not write an answer. At the stage of carrying out the plan, students tend to immediately calculate what is known in the problem, not even writing answers at all. Students do not check the answer so that the results of their conclusions and conclusions are wrong.

Abstract

Previous research has highlighted the challenges of improving students' mathematical skills, particularly in connecting mathematical concepts to everyday life and developing strong mathematical habits of mind. This research aims to integrate problem-based learning (PBL) into a mathematics module to enhance mathematical connection abilities and mathematical habits of mind. The ADDIE method was employed to achieve this goal, encompassing five stages: Analysis, Design, Development, Implementation, and Evaluation. The findings indicate that media, material, and language experts deemed the module highly suitable. Furthermore, the product was rated as highly practical based on teacher assessments, student responses, and observations during implementation. Effectiveness tests of the product, conducted through MANOVA, t-tests, and N-gain tests, revealed that the module is highly effective in enhancing students' mathematical connection abilities and moderately effective in improving their mathematical habits of mind. These findings underscore the importance of integrating digital learning technologies to increase the module's engagement and accessibility.

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

The purpose of this research was to find out the thinking processes of a concrete student in solving two- dimensional problems. The research method used is descriptive qualitative. The research subjects were two students taken using purposive sampling. The instrument used was the Test of Logical Operations and problem-solving tests. Stages of data analysis used are researching all data, making a cognitive classification of students, choosing concrete students to be used as research subjects, reviewing the results of concrete student work in solving mathematical problems, verify data and data sources that have been classified and transcribed in the presentation or exposure of data. The results showed that at the stage of understanding the problem and re-checking the answers, concrete students use the assimilation at the stage of planning to solve the problem of doing the disequilibration. At the stage of carrying out a plan to solve a problem, concrete students carry out the accommodation. During this study, it was found that students 'habits in mathematical problem-solving did not plan to solve problems, did not re-examine answers, and there were students' habits by interpreting the final results of problems. It can be concluded that the students' concrete thinking processes in solving two- dimensional problems vary according to the stages of problem-solving.

Abstract

This research aims to test the effectiveness of the Team Accelerated Instruction (TAI) towards the ability of the students to solve mathematics problems based on their initial ability. This study is an experiment with 367 students involved as the research sample taken using the cluster technique. The research variable is the problem-solving ability, the initial ability, and the learning model. Analysis of variance was used to analyze the data which leads to the conclusions that (1) the TAI is more effective than the Direct Instruction (DI); (2) the students having moderate initial ability performed better compared to the lower and the higher initial ability; (3) among the students with moderate initial ability, TAI was more effective to be used than DI; and (4) in the implementation of TAI and DI, the problem solving ability of the students is relatively similar.

Abstract

Purpose: This study aims to examine the influence of peer teaching that incorporates the local wisdom of gusjigang on the algebraic thinking skills of the student with introverted personality. Method: The research employed a descriptive quantitative approach with a Single Subject Research (SSR) A-B design. The participant was a second-semester mathematics student identified as an introvert. Data were collected through tests, observations and interviews. Analysis was conducted by comparing two phases: the baseline and the intervention. The within-phase analysis considered factors, such as interval duration, trend direction, stability, rate of change and data patterns. The between-phase analysis explored differences in variable values, trend shifts and changes in data levels across the two phases. Findings: The results demonstrate that peer teaching based on gusjigang local wisdom has a positive impact on the algebraic thinking abilities of the introverted student. This is reflected in the increase in the subject’s average score from 21.5 before the intervention to 68.5 after the intervention was implemented. Significance: The implementation of peer teaching infused with local wisdom plays an important role in encouraging introverted students to become more engaged in learning. By creating a more inclusive and supportive classroom environment, this approach helps to improve the algebraic thinking skills of students who are typically less active during mathematics instruction.
