Abstract

Disaster mitigation efforts in learning mathematics need to be done to foster a disaster awareness attitude in students through higher-order thinking skills (HOTS) questions in mathematics with a disaster context. One effort that can be done is to design mathematics problems in a disaster context. This study aimed to obtain valid HOTS mathematics questions in the disaster context for junior high school students. This research is development research that is limited to the self-evaluation and expert review stages only. This study obtained 16 HOTS questions in mathematics with disaster context for junior high school students, which were valid both in terms of content and construct. The disaster context used includes drought, tsunami, earthquakes, volcanic eruptions, climate change, landslides, forest fires, and floods. The implication of this research is that valid questions can be used by teachers in the teaching and learning process in the classroom.

Abstract

One of the main goals of school mathematics is the achievement of mathematical problem-solving abilities through problem-based learning. It is expected that these abilities can be achieved well by students. However, the complexity of the problem and minimum confidence become a problem when students experience complex situations created in the problem-based learning process. Scaffolding becomes essential because of the differences in each student's knowledge stored in long term memory. The purpose of the study was to analyze differences in mathematical problem-solving abilities with two different learning and based on initial mathematical abilities. Learning in the experimental class is problem-based learning with scaffolding, and then control class learning is problem-based without scaffolding. The research method used was a quasi-experimental design with a matching-only pretest-posttest control group design. Sample selection using purposive sampling to get samples with the same characteristics, the total number of samples is 60 students with each division 30. The initial mathematics ability has the same role in the mathematical problem-solving ability in the experimental and control classes. That is when students are in the high category then the ability of severe mathematical problem-solving. However, when the two classes are compared, the results are significantly different. Scaffolding becomes a factor that distinguishes the ability to solve mathematical problems.

Abstract

One of the cognitive skills that students must have is problem-solving ability. Therefore, a standardized test is needed to measure this ability. However, until now, the tests used to measure mathematical problem-solving ability were not standardized. This research aims to develop a valid and practical mathematical problem-solving test in the discussion of triangles and rectangles. This research is part of the R&D 4D type with steps: Defined (analysis to develop a test), Design (designing a problem-solving test form), and Develop (expert judgment and small group trials). The instrument in this research was the validation sheet used by the validator to assess each test item. The data analysis technique used the Aiken method for expert judgment and qualitative descriptive for development testing. The result is a valid and practical mathematical problem-solving test because the V-Aiken value is more than 0.532. Based on this, the instrument can be used to measure the mathematical problem-solving ability of junior high school students in the discussion of triangles and rectangles.

Abstract

This study aims to identify teachers' practices and barriers in carrying out a cognitive mathematics assessment during the COVID-19 pandemic. The type of research used is an online survey using a google form, which is spread over ten days via WhatsApp. This survey uses a qualitative approach. The research instrument was constructed from a pocketbook of periodic diagnostic assessment. A total of 78 primary to secondary school teachers from various regions in Indonesia participated. Data analysis was done descriptively, while data from open questions were analyzed using Atlasti 9. The study results present the practice of cognitive assessment regularly carried out by online-based mathematics teachers in high-grade elementary schools to secondary schools. In contrast, low-grade elementary schools are conducted by home visit. In practice, teachers experience several obstacles: the validity of the answers, limited time in the assessment, barriers from students themselves, and facilities. These obstacles cause the assessment results not to describe the cognitive level in-depth or provide valid and reliable information regarding students' achievement.

Abstract

The sudden change caused by the global pandemics of COVID-19 leads to the classroom transformation from classical face-to-face meetings into virtual. The development of technology enables classroom variation by providing various applications that can be employed to facilitate learning activities. Nonetheless, not all situations suitable to use advanced technology during distance learning. Some students are living in remote areas with limited internet connection. This study aims to offer an alternative if most of the students were having difficulties with the internet and minimum devices to download heavy applications. The alternative is by using a chat group with an emphasis on the students’ interaction during the lesson. This descriptive study was conducted at a university in Mataram, Indonesia. The subject was 17 students in the Mathematics Education Study Program who follow the course of Abstract Algebra. The data were gathered from students’ observation during the lessons and students’ written work in the middle semester test. The data were analyzed by using descriptive qualitative method. From the analysis, it was found that the students’ activity during distance learning was 83.5%. Furthermore, 88.23% of students achieved the minimum score for the middle semester test (more than 56). The study showed that mathematics teaching and learning could be done with a secure and straightforward access application to gain good results.

Abstract

The measure of the center is an essential topic in statistics. Pre-service mathematics teachers must have the ability to select and use measures of center. The inability to use and select appropriate center measures indicates a low understanding of center measures. Meanwhile, research on the ability to use and select the center's appropriate measures is very limited. This study explores the sources of error for pre-service mathematics teachers in using and selecting the appropriate measures of center. This study involved 177 pre-service mathematics teachers. This research is a qualitative study using the interpretive paradigm. Data were collected using a test containing two problems and clinical interviews. Data were analyzed qualitatively using grouping participant responses based on ways of thinking and ways of understanding to use and select center measures. The results showed that pre-service mathematics teachers could not select an appropriate measure of centers because they were too focused on measures of centers while ignoring the variance. In order to be able to select an appropriate measure of centers because variance must be considered simultaneously. The implication of this study results is the need for a learning approach that introduces concurrent measures of centers with data variance.

Abstract

Geometry is an essential subject for students. However, geometry, especially the cone, remains a challenging material for students. Besides, we need the proper media and context for learning mathematics on cone material. This research aims to develop a learning trajectory that utilizes the Megono Gunungan tradition as a context in the learning process using the Indonesian Realistic Mathematics Education (PMRI) approach. The research method used is Design Research, which consists of three phases of the study: preliminary design, experimental design, and retrospective study. This study's outcome is designing a learning trajectory on cone material using the Megono Gunungan tradition. This learning trajectory comprises four activities, including observing the interactive video of the Megono Gunungan tradition to discover cone elements, finding the concept surface area of a cone using origami paper, and grasping the cone concept volume with magic seeds, and solving contextual problems related to the cone. Studies have shown that using the Megono Gunungan context could help students improve their understanding of the cone concept. Furthermore, this study hoped could be an inspiration for exploring another local wisdom that can be a context in learning mathematics.

Abstract

Prospective elementary teachers (PET) are required to have sufficient mathematical and didactic knowledge about fractions, but many of them have difficulties explaining various concepts of fractions to students. Given the importance of prospective teachers’ knowledge of fractions, this study aims to investigate further the didactic knowledge of PETs’ didactic knowledge of fractions. Their knowledge is seen from their ability to construct contextual tasks about fractions based on number sense, problem-solving, mathematical literacy, and problem posing. PETs’ didactical knowledge is analyzed based on the anthropological theory of the didactic. This research method is qualitative with an internet-based research approach. The subjects of this study consist of 38 PsETs from a teacher education institution in Pekanbaru, Riau, Indonesia. The results of this study indicate that PsETs’ didactic knowledge of fractions is inappropriate, especially in the aspect of constructing contextual tasks about the division of fractions by fractions. PsETs tend to present the type of task associated with simple fraction operations and techniques in the form of standard algorithms. This study also indicates that PsETs’ theoretical knowledge is still limited to informal knowledge to support standard algorithms.

Abstract

Trigonometry, a discipline in mathematics, is often misunderstood by mathematics learners. To understand Trigonometry, students should start learning from understanding Mathematical concepts. Therefore, this study aims to analyze students' understanding of concepts in the Trigonometry course. This research is a qualitative descriptive study of the first semester students' conceptual understanding of the mathematics education study program at a university in Malang City. The data collected in this study consisted of the subject's work and transcripts of interviews. The instrument used in this study consisted of 6 questions about understanding the concept of trigonometric material. Analysis of the subject's work results is carried out to find out the right or wrong answers. Meanwhile, the interview transcripts were analyzed by coding to determine the factors that support conceptual understanding. The results showed that students with good conceptual understanding could solve trigonometric problems, while students with less understanding of concepts had difficulty solving trigonometric problems. The results of this study also found aspects that influence (encourage and inhibit) students in understanding the concept of trigonometry. Furthermore, this research is expected to contribute to trigonometry subjects' learning based on indicators of conceptual understanding in the Trigonometry course.
