This research is motivated by the importance of mathematical problem-solving skills for students. Problem-solving is one of the fundamental skills that students should possess; however, in reality, students' mathematical problem-solving skills are still considered low. This observation is drawn from various previous studies, interviews with mathematics teachers in several schools, and the results of tests involving mathematical problem-solving questions conducted by the researcher. A solution to enhance students' mathematical problem-solving skills is by using a contextual approach. Previous studies have indicated that a contextual approach can positively affect the improvement of students' mathematical problem-solving abilities. Based on these findings, this research aims to develop learning tools using a Contextual Approach for the topic of Two-Dimensional Shapes to facilitate valid and practical enhancement of students' mathematical problem-solving skills. The developed learning tools include a syllabus, lesson plans (RPP), and student worksheets (LKPD).
The development of this learning tool employs the 4D development model, consisting of Define (definition), Design (designing), Develop (development), and Disseminate (dissemination) stages. The developed tools were validated by three expert validators and subsequently tested with a small group comprising nine students and a large group comprising 31 students. The data collection instruments for this research include syllabus validation sheets, lesson plans (RPP), student worksheets (LKPD), and questionnaires for gathering feedback from teachers and students.
The analysis results in the Define stage include (a) Initial and final analysis, which involved interviewing teachers and observing the mathematical problem-solving abilities of students and the learning tools used in the teaching process. It was found that students' problem-solving abilities were low, and the teaching tools used by teachers had not been developed independently. (b) Student analysis was conducted through observations, interviews with students, and a literature review related to students' mathematical problem-solving abilities. It was found that students still faced difficulties in solving mathematical problems; (c) Material analysis involved identifying, detailing, and organizing the Two-Dimensional Shapes material relevant to the second semester of the eighth grade in the 2013 curriculum; (d) Task analysis involved analyzing the learning objectives related to Two-Dimensional Shapes material, serving as a reference for formulating the competency achievements from the selected learning objectives, (e) Learning objective analysis involved summarizing the results of task analysis and material analysis, which were used as a guide in developing the syllabus, RPP, and LKPD for the Two-Dimensional Shapes material. The Design stage involved the researcher designing the learning tools by creating an initial format consisting of four meetings with the scope of the material, namely: (a) Surface Area and Volume of a Cube, (b) Surface Area and Volume of a Rectangular Prism, (c) Surface Area and Volume of a Prism, (d) Surface Area and Volume of a Pyramid.
In the Development stage, the validation results for the syllabus, RPP, and LKPD met the criteria for being highly valid. The average validation score for the syllabus was 94.80%; for the RPP, it was 97.21%; and for the LKPD, it reached an average of 91.65%. The validated learning tools were then tested with a small group to assess their readability, resulting in data analysis meeting highly practical criteria with an average score of 95.26%. Following this, the revised tools, based on feedback from students, were tested again with a larger group. The practicality assessment through student response questionnaires met highly practical criteria with an average score of 96.77%, and through teacher response questionnaires with an average score of 93.75%. These findings indicate that learning tools based on the contextual approach are highly practical and effectively facilitate students' problem-solving abilities.
In the Dissemination stage, the learning tools based on the contextual approach, which have been tested, validated, and proven practical for students in facilitating mathematical problem-solving abilities, are disseminated by the researcher on a broader scale. This dissemination process involves presenting the findings in seminars, preparing articles for publication in journals, and delivering the learning tools to schools. The dissemination aims to share the successful outcomes and insights derived from the research, contributing to the broader educational community and potentially impacting teaching practices in the realm of mathematical problem-solving skills. Through seminars, articles, and distributing the developed tools to schools, the researcher contributes valuable knowledge and resources to enhance mathematics education.
