Abstract

Rendahnya pengetahuan dan hasil belajar siswa pada sub materi konfigurasi elektron dan hubungan konfigurasi elektron dengan tabel periodik di SMA Muhammadiyah 1 Pontianak disebabkan oleh kesulitan siswa dalam menuliskan konfigurasi elektron. Selama ini, media pembelajaran yang digunakan guru belum mampu membuat siswa paham terhadap penulisan konfigurasi elektron, sehingga perlu dikembangkan media pembelajaran yang dapat memudahkan siswa memahami materi tersebut. Penelitian ini bertujuan menghasilkan media pembelajaran Puztes yang valid, praktis dan efektif. Instrumen penelitian yang digunakan yaitu lembar validasi, angket respon siswa dan guru, serta lembar pretest dan posttest. Jenis penelitian ini adalah Research and Development [R&D] model ADDIE [Analysis, Design, Development, Implementation, Evaluation]. Penelitian ini menggunakan validasi isi dengan pendekatan Content Validity Ratio [CVR]. Dengan demikian, diharapkan media pembelajaran puztes yang dikembangkan layak digunakan sebagai media ajar pada sub materi konfigurasi elektron dan hubungan konfigurasi elektron dengan tabel periodik di kelas X SMA Muhammadiyah 1 Pontianak.

Abstract

Methods applied in schools have not been able to make students understand the sub-material of polar and nonpolar covalent compounds. One of the success factors of the practicum method is the use of the right practicum tools. Therefore, it is necessary to develop practical tools to make it easier for students to understand the concepts of polar and nonpolar covalent compounds. This study aims to produce a polarity and practicum tool on sub-material polar and nonpolar covalent compounds that are valid, practical, and effective. Validity is measured from the validator's assessment on material aspects and media using a validation sheet. Practicality is measured using teacher and student response questionnaires. Effectiveness is measured by the results of students' Pretest and Postest. This type of research is the development of the ADDIE Research and Development (R & D) model (Analysis, Design, Development, Implementation, and Evaluation). The results of the analysis show that the polarity practicum tool developed from the material and media aspects was stated to be very valid with an average validity value of 0.83 and 0.89, respectively. The practicality test results obtained very practical criteria with a practicality value of 96.64%. The aspect of effectiveness using the N-Gain value in the field trial results obtained N-Gain values of 0.72 with very high criteria. Thus, the polarity practicum tool developed is suitable for use as a sub-material learning media for polar and nonpolar covalent compounds.
