Abstract

This research aims to analyze the differences in critical mathematical thinking abilities who receive cooperative learning in the Student Teams-Achievement Divisions (STAD) type and those who undertake the cooperative learning process in the Numbered Head Together (NHT) type. This research design uses a quasi-experimental design. Apart from that, the population in this study were all students of the Taliwang State 1 Middle School West Sumbawa, while the sample was taken in two classes randomly from 18 existing classes (class VIII 3 and class VIII 4). Experimental class 1 consists of 32 people, while experimental class 2 consists of 32 people, so the total is 64 people. Data obtained from thinking ability tests were analyzed univariately, bivariate, and multivariate. The results of the univariate analysis show that the majority of respondents in Experiment 1 were male, 16 females, 16 people each (50%), the majority were of medium ability, 21 people (65.6%), then the High category was 7 people (22%) and the low category as many as 4 people (12.5%), while the majority of respondents in Experiment 2 were 17 people (53.1%) women while 15 people (47%) were men with 17 people (53.1%) in the medium category. High 9 people (28.1% and Low category 6 people (18.7%). Furthermore, the results of bivariate analysis showed that there were differences in students' mathematical critical thinking abilities between experimental class 1 and experimental class 2, while the significant value for the group category was 0.007, this means that there are differences in students' mathematical critical thinking abilities based on the categories of high, medium and low ability students. The results of the multivariate analysis show that the mathematical critical thinking abilities of students who received STAD-. type cooperative learning has a higher increase than students who receive NHT-type cooperative learning.

Abstract

The use of e-modules in mathematics learning significantly aids both teachers and students in the teaching and learning process. However, the design of e-modules has not been extensively linked to the cultural context in which students live. Therefore, this study aims to explore and analyze the needs of teachers and students in developing culturally integrated e-modules, particularly those reflecting the culture of Papua, for high school students. The research design employed is phenomenological. Participants included Mathematics teachers for grades X, XI, and XII in Nduga Regency, Papua Highlands, and 64 high school students (42 male and 22 female). Data collected from observations and interviews were qualitatively analyzed using Miles-Huberman Interactive Analysis. Findings revealed that the high schools still use the 2013 curriculum, relying on standard textbooks as teaching materials. These textbooks pose problems for students as they are often uninteresting, use formal language, are difficult to understand due to abstract content, and are not contextualized to students' daily lives. Additionally, the reduction in face-to-face learning hours, due to the school's location in a conflict area, hampers effective teaching and learning processes. Another interesting finding is that high schools in Nduga Regency have not yet utilized technology in learning, despite having internet access. These findings imply the need for teaching materials integrated with technology and local culture to help students understand mathematics concepts and assist teachers in teaching both inside and outside the school.

Abstract

Geometry self-efficacy is an essential affective aspect that will influence students in solving mathematics problems, especially geometry material. Therefore, teachers must be able to develop learning instructions that not only affect students' mathematical abilities but also strengthen students' affective aspects. This research explores students' geometry self-efficacy when learning to solve three-dimensional geometry problems through the 5E Instructional Model intervention. A grounded theory design was used to reveal the aims of this research. Participants in this research were one mathematics teacher and 22 students (12 girls and 10 boys) in class VIII at a state Junior High School in Indramayu Regency, Indonesia. The research involved the qualitative analysis of gathered data obtained through observation, questionnaires, interviews, and documentation, employing grounded theory analysis techniques, including open coding, axial coding, and selective coding. The findings revealed that students with high self-efficacy in geometry display confidence in describing and calculating the surface area and volume of three-dimensional geometric objects. Those with moderate self-efficacy in geometry are self-assured in addressing straightforward assignments but may need more confidence in tackling more complex tasks. Conversely, students with low self-efficacy in geometry tend to need more confidence and are prone to giving up easily. Therefore, this research emphasizes that the geometry self-efficacy level can influence how students act and complete 3D geometry tasks given by teachers in learning, especially 3D geometry learning.

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

Multiplication of fractions is one of the operations on fractions that tends to be easy, but it becomes a problem for students. Only a little previous research has examined the multiplication of fractions and the factors that cause this problem at the tertiary level. This study aims to describe the factors that cause problems in terms of the types of learning barriers that students experience. The research design is hermeneutics phenomenology. The participants in this study were 15 students aged 18-25 years, 7 boys and 8 girls, 9 students majoring in natural sciences during high school, and 6 students from social studies majors. The researcher is the main instrument, with a fraction multiplication test consisting of 2 questions developed by NCTM and a semi-structured interview guide as an additional instrument. Data is processed using NVivo-12-assisted thematic analysis to simplify the coding process. The study revealed that students experienced more learning difficulties when working on non-routine fraction multiplication problems. For routine problems, students experience learning difficulties with the type of ontogenic obstacle that is psychological (not careful). For non-routine problems, students experience learning barriers with epistemological types because they rarely work on word problems, as well as ontogenic obstacles that are conceptual and psychological.

Abstract

Number patterns were one of the mathematical concepts that were studied in junior high school. This concept was useful, but students tended to experience problems when learning it. Quite a lot of research has studied number patterns, but not many have attempted to study alternative solutions to optimize problem-solving abilities and learning motivation, especially using lesson study activities based on didactical design research. Therefore, this research aimed to optimize students’ problem-solving abilities and learning motivation with the preparation of didactic designs through lesson study activities. This research was conducted at a private junior high school in Mataram, Indonesia. Participants in this research were ten class VIII students (six boys and four girls). The researcher was the main instrument, with several additional instruments, such as learning design, observation sheets on problem-solving abilities and learning motivation, as well as documentation studies. The data were analyzed using qualitative data analysis. The research results revealed that the number pattern learning design was able to optimize problem-solving abilities and student learning motivation. Several factors that caused these positive results were the existence of contextual problems as trigger situations in learning and learning activities adapted to students’ hobbies. The recommendation from this research was that learning design should be prepared using didactical design research based on lesson study.

Abstract

3D geometry is an abstract concept that provides a visual representation of shape and space in mathematics. However, many students consider images in books to be representations of 3D geometry, thus requiring direct visualization for better understanding. Therefore, this research aims to institutionalize the use of 5E-IMARIB in 3D geometry learning to influence students' understanding of 3D geometry concepts and increase students' self-efficacy in geometry subjects. A quasi-experimental nonequivalent comparison group design was used in this research. Participants in this research were class VIII students at one of the private junior high schools in Indramayu Regency, who were then selected into two classes. The first class consisted of 20 students learning using the 5E-IMARIB, and in the second class, 22 students were using conventional learning. Data obtained from the results of the geometry understanding test and self-efficacy questionnaire were analyzed quantitatively using the independent t-test. The results showed that the average pre-test score for the experimental class was 17.83 and the average post-test score was 63.43. The average score of student learning outcomes in the control class was 18.78 for the pre-test and 52.35 for the post-test. Meanwhile, the average gain score in the experimental class was 0.52, and in the control class 0.41. Apart from that, the average increase in self-efficacy (SE) in the experimental class was 0.22, and in the respondent class was 0.20. Furthermore, based on statistical analysis using an independent t-test, it was concluded that there was an increase in understanding of 3D geometry concepts and students' self-efficacy after using 5E-IMARIB . The results of this research indicate that AR in 3D geometry learning has the potential to help students understand geometric concepts and student affectivity.         Keywords: 5E instructional model, augmented reality interactive book, 3D geometry, understanding of  geometry concepts, self-efficacy.DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp195-209
