Abstract

Mathematical problem-solving ability (MPSA) is an important competence that supports the development of higher-order thinking skills. However, research shows that students’ MPSA remains low, partly due to the lack of valid and reliable test instruments. This study aims to develop a MPSA test instrument in the form of essay questions on the content of algebraic forms, equations, and linear inequalities in one variable for seventh-grade students at SMP Negeri 13 Pekanbaru. The method used is development research with the Tessmer model, covering the preliminary and formative evaluation stages. The preliminary results indicate that mathematics learning in schools remains dominated by routine, result-oriented questions, while MPSA practice remains limited. Curriculum analysis indicates that the content of phase D algebra requires solving contextual problems, so the instrument was designed to measure the ability to understand problems, plan strategies, solve them, and interpret answers. The design phase produced Prototype I, consisting of 16 essay questions based on MPSA indicators and everyday contexts. Formative evaluation included self-evaluation, expert review, one-to-one, small group, and field tests. Self-evaluation and expert review showed that the instrument was highly valid (average score: 86.20%), with revisions to language, wording, illustrations, and instructions. One-to-one and small group tests produced Prototype II, which was then refined into Prototype III. Field testing with 37 students showed that 15 of 16 items were valid and reliable (coefficient 0.91 for package I; 0.85 for package II) and had good difficulty and discrimination levels, while one item was removed. Thus, the developed instrument is valid, reliable, and feasible for measuring students’ mathematical problem-solving ability.

Abstract

The main objective of this study is to develop teaching materials in the form of Student Worksheets using Question Probing Scaffolding with Perplexity AI to encourage creative thinking and mathematical problem-solving skills in the subject of Relations and Functions. The type of research used was Research and Development (R&D) using the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development procedure. This research was conducted in two schools, namely SMP Muhammadiyah 3 Bandar Lampung and SMPN 1 Menggala Timur in the 2024/2025 academic year. The research instruments used were validation questionnaires, tests, and documentation. The data obtained was then analyzed using quantitative and qualitative data analysis techniques. Based on the feasibility test by the validator, the student worksheets using Question Probing Scaffolding was categorized as very feasible. Based on the student response questionnaire, the student worksheets using Question Probing Scaffolding was categorized as very interesting. The N-Gain calculation results show that the use of student worksheets based on Question Probing Scaffolding produces an increase in creative thinking and problem-solving abilities in the high category. The t-test also shows a significant difference between the pre-test and post-test scores, proving that the developed student worksheets is feasible and effective for use in Relations and Functions material. Overall, this student worksheets is considered practical, easy to implement, and able to improve the learning outcomes of junior high school students.

Abstract

This study aims to assess the validity and practicality of electronic student worksheets (LKPD) based on the Discovery Learning model, using LiveWorksheets, for Algebraic Expressions in Grade VIII Junior High School students. The research follows a Research and Development (R&D) approach, employing the ADDIE development model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The study was conducted at SMP Muhammadiyah 6, Yogyakarta. Data were collected using expert validation instruments from subject-matter and media experts, as well as student response questionnaires. The findings reveal that the developed electronic worksheets were rated highly valid by subject matter experts (82.89%) and by media experts (94.48%). Regarding practicality, student assessments indicated 88% for small-group trials, categorized as very practical, and 79.82% for large-group trials, categorized as practical. These results indicate that the electronic worksheets are valid and practical for use in classroom instruction.

Abstract

This study uses a Systematic Literature Review (SLR) technique with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology through Google Scholar and Web of Scientific Journals Publish or Perish to investigate the relationship between students' critical thinking skills and self-efficacy through a review of 24 publications published between 2018 and 2025 in various journals. Based on the analysis findings, research on critical thinking skills and self-efficacy has been conducted extensively at different levels of education, with the majority (73%) performed in junior high schools. Furthermore, 62% of quantitative research is often used, and this research predominantly develops critical thinking skills. This dominance indicates that self-efficacy is generally considered a supporting variable rather than the primary focus of the topic, thereby opening opportunities for future research on broader subjects and methods.
