Teachers often face challenges in creating effective learning materials, particularly in mathematics. Traditional lecture methods and insufficiently engaging learning tools can lead to student disinterest. Hence, it is essential to develop mathematics learning media that stimulate interest and connect to real-world experiences, including local cultural practices. Therefore, this study aimed to design effective learning media for Year 8 students focused on number patterns and to assess the validity of this media. This research adopted a development approach, utilizing the Analysis, Design, and Development (ADDIE) method. The development process was limited to the Analysis, Design, and Development stages. An assessment questionnaire was used to evaluate the validity of the video media, with input from both media experts and material experts. Five experts from each field were consulted for media validation. Results of the validation process indicated that the video media scored 88% and 87% in the material expert and media expert evaluations, respectively. These scores met the criteria for validity, indicating that the media is suitable for use in the classroom.

This study employed GeoGebra to develop interactive learning instruments for SLETV content, using the 4-D Thiagaradjan model as the framework, involving four phases: define, design, develop, and disseminate. The investigation included two eighth-grade math teachers and fourteen-year-old eighth-graders, and observational data were collected through needs analysis, interviews, and questionnaires. The data collection comprised need analysis, interviews, and surveys. Before trial implementation, three crucial development requirements had to be met: validity, practicality, and efficacy. The validation of learning instrument formats, illustrations, language, and content showed valid. The research findings indicate that the developed learning instruments were effective, with an average student score of 74.3 on the pretest and 87 on the posttest (meeting the minimum criteria of mastery learning). Teacher's ability to manage learning was rated as very good, with an average score of 4.4. The observation of learning implementation showed an average score of 4.4 in the very good category (practical). The learning instruments based on RME can be used to enhance students' mathematical literacy and learning interest.

The guided inquiry learning model is a student activity that emphasizes maximally training critical thinking skills. The learning instruments developed must be adapted to the syntax/stages of the guided inquiry learning model. Several learning instruments have been developed to assist teachers in making teaching materials. However, many teachers have not mastered technology, especially learning media using applications. Therefore, teachers need learning applications in schools, such as the GeoGebra applet. This study aims to develop valid guided inquiry-based learning instruments using GeoGebra applets for circles. This research is development research employing Plomp’s model and involving preliminary research and prototyping stages. The data was collected by compiling the comments and input from the validator through validation sheets related to learning instruments (lesson plans, worksheets, and GeoGebra applets). The results of the data analysis showed that the learning instruments were declared valid with an average lesson plan score of 4.75, an average student worksheet validation score of 4.60, and an average value of the total validation of GeoGebra applets of 4.94. Further research should assess the practicality and effectiveness of the instruments.

In studying geometry, it is common for students to make various errors when working on word problems. Although some students understand the example problems, they may be confused and make errors when presented with different questions. This study employed a qualitative descriptive approach to examine the types and causes of errors made by Grade 8 students from a junior high school in Pronojiwo, Indonesia. The study involved 40 students, with six students selected for interviews. Data were collected using descriptions and interviews. The research employed three procedural stages: preparation, implementation, and data analysis. Data analysis involved data reduction, data encoding, and conclusions. The analysis revealed that 23.3% of students made conceptual errors, 27% made procedural errors, and 44.5% made technical errors. The factors contributing to these errors included students' lack of focus on reading the questions, limited understanding of the material, haste in completing the questions, insufficient knowledge of the problems in the questions, and carelessness in checking their answers.

This study aims to investigate the proficiency of prospective mathematics teacher students in mathematical representation. To achieve this goal, we used a qualitative research design with a descriptive approach. The research subjects consisted of three undergraduate students from Mathematics Education department at a private university in Yogyakarta. Data were collected using a test for mathematical representation ability and interviews. The data were analysed descriptively using techniques by Miles and Huberman. It shows that the mathematical representation ability of prospective teacher students was in low category. This can be seen from the average achievement of indicators of mathematical representation ability (34.74%). The ability to create and use representations for collecting/organizing, recording, and communicating mathematical ideas is 33.33%. The ability to select, apply and translate various forms of representation mathematics to solve problems is 29.76%. And the ability to use multiple representations is 41.11%.

This study describes the results of research on the implementation of the Quizizz application in learning with distance learning mode. It has three main objectives 1) to find out how to apply the Quizizz application as an assessment medium based on higher-order thinking skills; 2) the impact of the application of Quizizz as an assessment medium based on higher-order thinking skills on students' learning motivation; and 3) supporting and inhibiting factors for the implementation of Quizizz. This study used a qualitative descriptive approach and data were collected using observation, implementation, interviews, questionnaires, and documentation. The data analysis was carried out by grouping and presenting the data of 69 respondents and drawing conclusions. The use of Quizizz as an assessment medium based on HOT skills is carried out during daily tests, mid-semester, and end-semester tests. Based on the data, it was obtained information that the level of student learning motivation using Quizizz media based on higher-order thinking skills showed an average of 69.91. Furthermore, the supporting factor for the application of Quizizz media is that students are familiar with the use of Quizizz and the many tasks available on Quizizz. The inhibiting factor is that the internet connection at the student's residence still tends to be less supportive of online distance learning.

This study was motivated by student errors in trigonometry. This study aimed to describe the types of student errors in solving trigonometry problems using the Newman error analysis procedure. This research is descriptive qualitative with the subjects of vocational high school students. Data collection involved written tests, depth interviews, and documentation. The results show that most students made comprehension and transformation errors. The comprehension errors consisted of not writing down what was known and asked; immediately writing down the completion process with the wrong formula and incorrect understanding of the concept of the basic trigonometric formula. The transformation errors were not being able to transform information on the problem into the mathematical model, and incorrect in mentioning the formula.
