Abstract

Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran matematika dengan metode penemuan terbimbing pada materi bangun ruang sisi lengkung yakni berupa Rencana Pelaksanaan pembelajaran (RPP) dan lembar Kerja Peserta Didik (LKPD) yang teruji kevalidannya. Penelitian pengembangan perangkat pembelajaran matematika ini menggunakan model Research and Development (R&D). Tetapi dikarenakan adanya pandemi COVID-19 hanya 6 tahapan saja yang dilakukan yaitu 1) potensi & masalah, 2) pengumpulan data, 3) desain produk, 4) validasi desain, 5) revisi desain dan 6) produk akhir. Instrumen pengumpulan data yang digunakan adalah lembar validasi RPP dan lembar validasi LKPD. Teknik pengumpulan data yang digunakan adalah non tes dengan menggunakan angket lembar validasi dari 2 orang dosen pendidikan matematika FKIP UIR dan 1 orang guru matematika SMP Negeri 4 Kunto Darussalam. Teknik analisis data yang digunakan adalah analisis deskriptif kuantitatif yaitu dari analisis data validasi. Dari hasil penelitian diperoleh hasil validasi RPP sebesar 88,53% dengan kategori sangat valid dan LKPD sebesar 88,71% dengan kategori sangat valid. Berdasarkan hasil penelitian ini diperoleh perangkat pembelajaran matematika dengan metode Penemun Terbimbing pada materi Bangun Ruang Sisi Lengkung kelas IX SMP yang teruji kevalidannya.

Abstract

This study aims to produce mathematics learning tools in the form of Learning Implementation Plans (RPP) and Student Worksheets (LKPD) with The Power Of Two strategy in Junior High Schools, which have been tested to be very valid. The development of learning tools in this study uses the R&D development method using the ADDIE model, namely: 1) Analyst, 2) Design, 3) Development, 4) Implementation, 5) Evaluation. The research data collection instruments were the RPP validation sheet, LKPD validation sheet, and teacher response questionnaires. The data collection technique used was validation data from 2 Lecturers of Mathematics Education FKIP UIR and two mathematics teachers at SMP Negeri 6 Siak Hulu. The technique used is validation data analysis. From the study results, the results of the RPP validation were 87.67 with a very valid category and LKPD 86.26 with a very valid category. Based on this research, it was obtained that the mathematics learning device with The Power Of Two strategy on the flat-sided geometry material in Junior High School was very valid, so the learning device could be diagnosed as a valid device to use.

Abstract

This development research aims to produce learning device products using a valid Missouri Mathematics Project (MMP) model. The learning device products developed to consist of the Learning Implementation Plan (RPP) and Student Worksheets (LKPD). This type of research is development research with the ADDIE model, which has been modified into four stages (Analysis, Design, Development, and Evaluation). The data collection instruments used in this study were validation sheets and teacher response sheets to measure the validity and practicality of learning devices. The data analysis used is descriptive data analysis which describes the level of validity and practicality of the product. The data was obtained from the validation results by two mathematics education lecturers and two mathematics education teachers. The results obtained in the form of RPP validation results are 83.33% with valid criteria, and LKPD validation results are 87.88% with very valid criteria, then the results of the practicality questionnaire for practical RPP with an average of 83.33% and LKPD in the category very practical with an average of 87.5%. Thus, it can be concluded that this development research resulted in learning tools (RPP and LKPD) that were tested for their validity and practicality.
