Abstract

This study aims to produce Problem-Based Learning student worksheets (LKPD-PBL) on statistical material on the ability to understand mathematical concepts for class VIII SMPN 17 Bengkulu City, which are valid and practical. The urgency of this study is based on the importance of enhancing students' ability to understand mathematical concepts. Preliminary observations indicate that many students struggle to deeply comprehend statistical concepts due to conventional teaching methods. Therefore, an innovation in teaching materials is needed to help students develop their conceptual understanding through the Problem-Based Learning (PBL) approach. This study was a Design Research (DR) using type development studies, consisting of level preliminary and level prototyping with flow formative evaluation, self-evaluation, one-to-one, expert review, small group, and field test. The study instrument consists of a validity questionnaire, a practicality questionnaire, and interviews. The study results showed that the development of LKPD-PBL was: 1) valid based on the results of revisions through the expert review and one-to-one stages regarding aspects of material, construction, language, and readability; 2) practical based on the results of revisions through the small group stage regarding ease, clarity, and usefulness.

Abstract

Supporting the development of university students’ cognitive skills in higher education necessitates the design of instructional materials that cultivate critical thinking. Integrating technology into teaching resources has become prevalent in higher education, proving effective in advancing students' skills. This study aims to evaluate the validity of a digital trigonometry module based on LiveWorksheet, assess its practicality from the users' perspective, and determine its effectiveness in enhancing mathematical communication skills. The study follows a research and development with five phases: (1) analysis, (2) design, (3) development, (4) implementation, and (5) evaluation. Participants included two experts-one in mathematics education and another in ICT education and 62 students (Class A, n=32; Class B, n=30). These students were enrolled in a trigonometry course taught by the researcher. Data were gathered via questionnaires and mathematical communication skill assessments, with qualitative descriptive analysis used to address the research objectives. Results indicate that the digital trigonometry module meets established validity criteria. The implementation findings demonstrate that the module is both practical for users and effective in enhancing students' mathematical communication skills, with average student performance reaching a high level. These findings suggest that LiveWorksheet-based digital instructional materials, particularly when incorporating media such as videos and interactive quizzes, can significantly enrich learning support
