This study aims to describe the numeracy ability of students at the cognitive level of reasoning grade VIII State Junior High School 5 Rambah Hilir in solving algebraic domain numeracy problems. This study uses a qualitative approach with a descriptive type. The subjects in this study are students in grades VIII-3 of State Junior High School 5 Rambah Hilir which totals 23 students. Then 6 students with qualifications 2 students with high numeracy skills, 2 students with moderate numeracy skills and 2 students with low numeracy skills were selected as interview subjects. The technique of checking the validity of the data uses triangulation techniques. The results of the study showed that the numeracy ability of students at the cognitive level of reasoning at State Junior High School 5 Rambah Hilir, namely students with a high level of numeracy ability at the cognitive level of reasoning, were able to meet the three indicators of numeracy ability at the cognitive level of reasoning, namely namely analyzing data and information, evaluating, and inferring. Students with a level of numeracy ability at the cognitive level of moderate reasoning are only able to meet two indicators of numeracy ability at the cognitive level of reasoning, namely analyzing data and information, and evaluating. Students with a low level of numeracy ability at the cognitive level of reasoning are only able to meet one indicator of numeracy ability at the cognitive level of reasoning, namely analyzing data and information.

This study aims to analyze students' mathematical creative thinking skills based on their academic abilities. The essential elements that include creative thinking are 1) fluency; 2) flexibility; 3) originality; 4) Elaboration. This study uses descriptive research with a qualitative approach. The subject in this study is a student of Junior High School 4 Koto Gasib. The subject of this study is grade IX students as many as 28 purposive sampling students who have studied the data collection techniques used in this study, namely in the form of mathematical creative thinking ability test questions on TVLES material and interviews. The results of the analysis showed that the average score was 56.25 based on the four indicators, students had quite high creative thinking skills. The average ability of students to think creatively in the Elaboration category is 89% which indicates a very high Average ability of students to think creatively in the originality category is 75%, the average ability of students to think creatively in the flexibility category is 23%, the average ability of students to think creatively in the fluency category is 38%.

This study aims to develop Group Investigation (GI)-based teaching materials to enhance the critical thinking skills of vocational high school (SMK) students in understanding and solving problems related to composition functions. Using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), the research produced teaching materials validated by subject matter experts, ensuring their quality, relevance, and alignment with curriculum objectives. Through GI stages—grouping, planning, investigation, organizing, presenting, and evaluating—students not only deepened their understanding of composition functions but also developed critical thinking, problem-solving, and teamwork skills. The findings highlight contribute to the development of innovative teaching materials and provide a foundation for transforming mathematics education into a more practical and effective discipline, particularly for vocational students.

Development of Articulate Storyline 3 Learning Media for Mathematical Computational Thinking Skills

Fri, 28 Feb 2025 00:00:00 +0000

Mathematical computational thinking skills are essential in mathematics learning, particularly in training systematic problem-solving abilities. However, the limited availability of interactive and effective learning media has remained a significant obstacle to developing these skills. This study aims to develop learning media based on Articulate Storyline 3, which is designed to enhance students' mathematical computational thinking skills. The method employed in this research is Research and Development (R&D) using the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The subjects of the study were high school students selected through purposive sampling. The research instruments included expert validation questionnaires, user response questionnaires, and tests to assess computational thinking skills. The study results have shown that the developed learning media has achieved a very high level of validity according to evaluations from both material and media experts.

Additionally, user responses have demonstrated high satisfaction with the interactivity and ease of media use. Field trials have revealed a significant increase in students' mathematical computational thinking skills after using the learning media. Based on these findings, learning media based on Articulate Storyline 3 has effectively improved mathematical computational thinking skills. These results are expected to contribute positively to more interactive and practical mathematics education innovations.

This study aims to describe the ability of students' mathematical representation on the material of a two-variable linear equation system reviewed from Self Efficacy. The type of research used is qualitative research with descriptive methods. The sampling technique used is purposive sampling. The data collection technique used a test of students' mathematical representation ability, self-efficacy questionnaire, semi-structured interviews, and documentation. The data obtained was then analyzed in 3 stages, namely data reduction, data presentation and conclusion drawn. The results showed that students with a high self-efficacy category met all three indicators of mathematical representation ability, namely using visual representations to solve problems, solving problems by involving mathematical expressions and writing Steps to solve mathematical problems with words. Students with the category of self-efficacy Moderate meet two indicators of mathematical representation ability, namely using visual representation to solve problems and solve problems by involving mathematical expressions. Students with low self-efficacy meet one indicator of mathematical representation ability, namely solving problems by involving mathematical expressions.
