KELAYAKAN BAHAN MOTIVASI PESERTA DIDIK (BMPD) UNTUK PEMBELAJARAN KIMIA DI SMA KELAS X SEMESTER 2

THE FEASIBILITY OF STUDENT MOTIVATION MATERIALS (SMM) FOR CHEMISTRY LEARNING AT SENIOR HIGH SCHOOL CLASS X SECOND SEMESTER

Penelitian ini bertujuan untuk menghasilkan Bahan Motivasi Peserta Didik (BMPD) yang layak digunakan untuk memotivasi pada pembelajaran kimia di SMA kelas X semester 2. BMPD dikembangkan mengikuti tahapan analyze, design, develop, implement, evaluate (ADDIE). Tahap evaluasi meliputi sub tahap evaluasi formatif dan evaluasi sumatif. Dalam penelitian ini pengembangan BMPD sampai tahap evaluasi formatif. Kriteria kelayakan meliputi validitas (isi dan konstruk), kepraktisan, dan efektivitas. Kriteria validitas didasarkan data hasil expert judgement dari tiga orang validator. Kriteria kepraktisan dan efektivitas didasarkan penilaian yang diberikan oleh tiga orang guru kimia sesaat setelah uji coba BMPD. Keseluruhan data dianalisis secara deskriptif. Hasil penelitian menyimpulkan bahwa kesembilan BMPD yang dikembangkan memenuhi syarat kelayakan. Setiap indikator dari kesembilan BMPD sebagai pemotivasi memperoleh penilaian dari validator dengan modus (Mo) minimal 4 pada rentang skor 1-5 dengan nilai percentage of agreement antar validator di atas 75%. Kesembilan BMPD dinyatakan memenuhi syarat kepraktisan dan efektivitas karena pada setiap indikatornya memperoleh penilaian dari guru pengguna dengan modus (Mo) 4 pada rentang skor 1-4 dengan nilai percentage of agreement (R) antar guru pengguna di atas 75%.

Kata kunci: Bahan Motivasi Peserta Didik (BMPD), validitas, kepraktisan, efektivitas, percentage of agreement.

This study aims to produce Student Motivation Materials (SMM) that feasibility to use in learning chemistry at senior high school class X second semester. SMM is developed following steps analyze, design, develop, implement, evaluate (ADDIE) stages. The evaluation stage includes the formative evaluation and summative evaluation sub-stages. In this research, the development of the SMM until the formative evaluation stage. The eligibility criteria includes validity (content and construct), practicality, and effectiveness. The validity criteria are based on data from the expert judgment from three validators. Practicality and effectiveness criteria are based on the assessment given by three chemistry teachers shortly after the SMM trial. All data were analyzed descriptively. The results of the study concluded that the nine SMMs developed reach the eligibility requirements. Each indicator from the nine SMM as a motivator receives an assessment from the validator with mode (Mo) at least 4 in the score range 1-5 with a percentage of agreement between validators above 75%. The nine SMMs were declared to reach the requirements for practicality and effectiveness because each indicator received an assessment from the user teacher with mode (Mo) at least 4 in the score range 1-4 with a percentage of agreement (R) between user teachers above 75%.

Keywords: Students' Motivation Materials (SMM), validity, practicality, effectiveness, percentage of agreement.
