Abstract

The integration of technology into learning needs to be done following the times. Many learning resources are still not integrated with technology that it hinders the attainment of students' problem-solving skills. Therefore, this research aims to determine the effect of android-based contextual teaching materials on students' problem-solving skills. This research is quasi-experimental with a pretest-posttest control group design. The research population was all students of class X of SMAN 3 Mataram. The research sample used class X MIA 3 as the control group and class X MIA 5 as the experimental group. The data collection instrument used a test with several problem-solving indicators. Problem indicators used include solving, planning, explaining solutions, and evaluating. Data analysis used t-test and N-gain to see the magnitude of the effect. The results of the t-test showed a data significance value of 0.004. This result is still below the α value (sig. < 0.05), meaning that there is a positive effect from the treatment given. The experimental group got a higher increase than the control group. The difference in the increase occurred for the sub-materials and all indicators of problem-solving skills. Therefore, the conclusion of the study is that android-based contextual teaching materials have a positive effect on students' physics problem-solving skills.

Abstract

Penelitian ini bertujuan untuk menyelidiki penyebab kesalahan peserta didik dalam memahami materi usaha dan energi. Penelitian dilaksanakan di MAN 2 Yogyakarta dengan jumlah responden sebanyak 49 peserta didik kelas X. Jenis penelitian adalah deskriptif kuantitatif dengan metode campuran yaitu survei dan wawancara. Instrumen yang digunakan berupa soal berbentuk esai sebanyak sepuluh dan daftar pertanyaan wawancara terstruktur untuk menambah bahasan atau hasil temuan. Analisis data menggunakan analisis deskriptif. Hasil penelitian menunjukan beberapa penyebab kesalahan pemahaman yaitu: (1) konsep awal peserta didik mengenai usaha dan energi ketika di Sekolah Menengah Pertama (SMP) masih tertanam kuat dan terbawa hingga SMA; (2) guru dan peserta didik jarang mengulang dan mengaitkan materi usaha dan energi dengan materi sebelumnya yaitu vektor dan hukum Newton; (3) kemampuan matematika peserta didik masih rendah terutama bagian trigonometri; (4) guru dan peserta didik masih kurang dalam latihan interpretasi grafik materi usaha dan energi; (5) peserta didik tidak terbiasa menjawab soal secara sistematis dengan urutan interpretasi, analisis, evaluasi, dan simpulan; (6) peserta didik tidak terbiasa menggambarkan sketsa sebelum menjawab soal.
