Abstract

Critical thinking ability is a crucial ability in mathematics, both at the elementary, secondary, or college level. However, this critical thinking ability is still low. Therefore, the researchers want to study the problem at what level the students are doing in solving mathematical critical thinking problems. The research method used a qualitative method, with the implementation analyzing students who deal with mathematical critical thinking ability problems. The study was conducted at one of the State Junior High Schools in Kroya District, Indramayu, West Java. As a result of the study, information was obtained about students who could not solve the problems presented in mathematical critical thinking ability problems, so they did not understand which strategies should be used to solve problems that could be solved.

Abstract

Converting mixed numbers into common fractions is one of the formula problems in learning fractions which is a problem in learning. However, not many studies have examined this conversion. In addition, there are not many studies that try to provide solutions to the conversion problem. Therefore, this study aims to identify the types of learning barriers students experience when converting mixed numbers into common fractions and provide alternative solutions to minimize these learning barriers. The research design used to achieve this goal is didactical design research (DDR). DDR was chosen because it uses the results of identifying types of learning barriers to develop didactic designs in learning fractions. The participants in this study were math teachers with 26 years of age and less than 5 years of teaching experience. The main instrument in this study was the researcher using several additional instruments, such as fraction comprehension tests, interview guides, and didactic designs. The data was then analyzed using qualitative data analysis. The results of the study revealed that students indicated that they experienced learning difficulties with different types of epistemological obstacles because they rarely start learning with everyday life problems. The solution offered in the didactical design is the use of the problem as an initial situation in learning which students will then respond to in the form of a didactical situation. The recommendations offered in this study are the implementation of the didactic design itself.

Abstract

Parents play an important role during online learning during the Covid-19 Pandemic. However, there are still not many studies that examine parents' perspectives regarding online learning. Therefore, this study aims to examine the perspective of parents regarding the problems experienced by students during online mathematics learning. Participants in this study were 47 parents of students whose ages ranged from 35 to 50 years. The instrument used was an interview guide in the form of a semi-structured interview. Data were analyzed using NVivo-12-assisted thematic analysis. The results of the study show that parents think students have problems in terms of low understanding of math material and children learning less than optimally while at home. However, some parents also revealed that there were no obstacles during online learning during the Pandemic. The results of this study then recommend that parents immediately provide information to the teacher when they find that children cannot solve problems and parents cannot help children in solving these math problems.

Abstract

Each student has their own characteristics and way of doing 3D geometric thinking. The way of thinking that students do influences the resulting understanding of the concept of 3D geometry. Therefore, this study aims to investigate students' geometric thinking based on the level of achievement of students in completing the 3D geometric thinking ability test (3D GTA). This study uses an exploratory case study design. The participants who voluntarily participated were 33 junior high school students (14 boys, 19 girls) in one of the schools in Indramayu Regency, Indonesia. Data obtained from the process of observation, tests, interviews, and documentation were analyzed qualitatively using Atlas. ti 8 software. The findings revealed that students with low 3D GTA achievements experienced difficulties in representing and calculating the surface area and volume of 3D shapes. In addition, students with moderate 3D GTA achievements experienced difficulties in representing 3D shapes but were able to translate 2D shapes from 3D shapes. Furthermore, students with high 3D GTA achievements experienced difficulties in calculating the surface area and volume of 3D shapes, but were able to use appropriate formulas and were able to interpret the comparisons of 3D geometric shapes well. The results of this study have implications for helping teachers identify student characteristics in understanding the concept of 3D geometry and connections with 2D geometry.

Abstract

Cognitive diagnostic models (CDMs) are multidimensional multivariate verification flow models with complex structure. In this research, these models were used to investigate the status of eighth grade high school students in mathematics using the TIMMS questionnaire. The cognitive diagnostic test based on 13 attributes including 32 questions was conducted on a sample of 274 students who were selected based on the multi-stage cluster sampling method among the students of Firuzkoh city. IRT and RESMA models were used to determine the psychometric properties of the questions. Data analysis using DINA and DINO models in cognitive diagnostic mathematics modeling showed that 13 attributes explain the mathematical performance of eighth-grade students. The result shows that Afghan students have a weak mastery level in most features compared to 45 other countries (the countries that were included in the TIMMS questionnaire) also, general results show that the examinees perform better in the field of numbers (0.49), while they perform worse in data and chance (0.12 ). Moreover, some difference exists in estimating item parameters under the DINA and DINO model, such as Item 3 and Item 27. One possible explanation is that the DINA model is completely compensatory while the DINO model is fully non-compensatory. Similar to the results under the DINA model, the SEs of guessing parameters are lower than those of slipping parameters under the DINO model.

Abstract

This study aims to analyze the ability of SL using statistical literacy ability test questions integrated with Indonesian education issues through a quantitative descriptive research approach to 116 students of the Elementary School Teacher Education Study Program at Muhammadiyah University Muara Bungo. The results showed that students were still low in Statistical Literacy skills. These results can be seen from 75% of students who scored below 60 and 25% of students who scored above 60 on the Statistical Literacy ability test. Then, it can be seen from the average ability of students to solve SL test questions based on Indicators, namely 71.33% in indicator 1, 53.16% in indicator 2, and 57.18% in indicator 3. At the same time, the average student who is able to solve SL questions is 28.67% in indicator 1, 46.84% in indicator 2, and 42.82% in indicator 3. Based on in-depth interviews, researchers see the main factor in the low SL ability of students being that they have not mastered descriptive statistics. The main factor that helps students solve SL questions is the Indonesian Education Issue approach. Researcher suggest that further research needs to be done that can improve students' SL skills through the application of learning models, the development of learning models, or the application of learning strategies to solve SL problems.

Abstract

Lines and angles are quite important mathematical concepts. This is proven because lines and angles cannot be separated in life. However, lines and angles actually become a problem/obstacle in the classroom. The purpose of this research is to determine the description of students' learning obstacles in the material on lines and angles for class VIII MTs NW Pringgajurang, then a didactic design for learning lines and angles will be prepared. The research design used is didactical design research-interpretive. The participants in this research were Class VIII students at MTs NW Pringgajurang with an age range of 12 to 14 years. The researcher is the main instrument in this research, with several additional instruments such as tests for understanding lines and angles, student biodata, interview guides and didactic designs for lines and angles. The data analysis technique used in this research is thematic data analysis. This thematic analysis is used as a basic foundation for the analytical process in qualitative research, by paying attention to the results of the data collection carried out. The results of the research show that students experience learning obstacles with ontogenic psychological and ontogenic conceptual types. With this Android-based didactic design, it is hoped that it will be able to minimize barriers to students' learning on line and angle material at MTs NW Pringgajurang.
