Abstract

Penelitian ini bertujuan untuk mengembangkan multimedia presentasi berbasis problem based learning berbantuan canva pada materi fluida statis yang layak dan efektif digunakan dalam pembelajaran. Jenis penelitian yang digunakan dalam penelitian ini ialah jenis penelitian Research and Development (R&D) dengan model pengembangan 4D (four-D). Instrumen yang digunakan ada tiga yaitu, instrumen kelayakan media pembelajaran ditinjau dari ahli media, instrumen kelayakan materi ditinjau dari ahli materi dan instrumen respon siswa terhadap keefktifan media pembelajaran. Subjek dalam penelitian ini yaitu 30 siswa kelas XI MIA di SMA Negeri 16 Medan. Hasil penelitian menunjukkan dalam uji coba yaitu 30 siswa memperoleh nilai rata-rata 91,4 dikategorikan sangat layak. Hasil perolehan nilai 30 siswa kelas XI MIA-3 memperoleh rata-rata pretest 25,5 dan postest 85 jika dihitung dengan gain ternormalisasi menunjukkan nilai gain sebesar 0,78 dengan kategori tinggi. Adanya peningkatan tersebut menunjukkan bahwa multimedia presentasi berbasis model problem based learning berbantuan canva pada materi fluida statis efektif digunakan di SMA Negeri 16 Medan.

Abstract

The purpose of this study was to develop an e-book physics learning media based on problem based learning (PBL) using a professional flip pdf on the Business & Energy material and to test the feasibility of the e-book media developed through expert validation and to find out the attractiveness of teacher and student responses. The research and development steps are guided by the 4-D Thiagaraja cycle model (Define, Design, Develop, Disseminate). The develop stage involves two validators to assess the feasibility of the material and media. The Disseminate stage involved 31 students (at SMA N 3, Binjai). The data collection instrument used was a questionnaire with qualitative descriptive data analysis. The results of this study indicate that; (1) The variable of the feasibility test of e-books as learning media by media experts, the overall average score is 100% and by material experts, the overall average score is 98% which belongs to the high category, meaning that e-books developed with professional flip pdf is very feasible to use. (2) The effectiveness variable has an overall average score of 90.93% which is classified in the very effective category, meaning that the e-book is quite effective in helping students increase the value of learning physics in the work & Energy material. (3) The results of the physics teacher response at SMA N 3 BINJAI to the e-book with an overall average score of 88.2% with the Eligibility criteria and product trials for students to respond to the e-book with an overall average score of 86 % with Eligible criteria, it can be concluded that the e-book received a good response from teachers and students.

Abstract

This development research aims to produce physics LKPD based on Cooperative GI on the subject matter of Static Fluid which is feasible to be applied in the physics learning process at school and determine the response of students after using the developed LKPD.The subjects in this study were students of class XI MIPA totaling 18 students. This type of research is a development research or Research and Development (R&D) using the 4D Model. The instruments used in this study consisted of a validation questionnaire for material experts and learning experts, a questionnaire for the assessment of physics teachers, and a questionnaire for students' responses to the physics LKPD based on cooperative learning. The data analysis technique used in this research is descriptive. From the results of data analysis obtained material expert validation of 82%, learning experts 81%, physics teacher assessment of 90% with each of these percentages included in the very good category. While in the broad trial the percentage of student responses with a sample of 15 people was 86.06% with very good criteria, so that based on the results of validation, physics teacher assessment and student responses it can be concluded that Cooperative-based physics LKPD on the subject matter of Static Fluid is feasible to use in the learning process. Keywords: Development, LKPD, STEM, Elasticity and Hooke's Law
