Berdasarkan analisis data diperoleh hasil validasi ahli materi secara keseluruhan sebesar 94% dengan kriteria sangat valid. Validasi ahli media secara keseluruhan sebesar 98% dengan kategori sangat valid. Uji praktikalitas guru dilakukan pada 3 orang guru dan mendapatkan hasil sebesar 87% dengan kategori sangat praktis. Respon peserta didik didapat dari 15 orang peserta didik dilihat dari hasil angket sebesar 81% dengan kategori sangat praktis. Peningkatan self efficacy peserta didik dapat diketahui melalui perhitungan N-gain berdasarkan hasil pretest dan posttest. Rata-rata N-gain yang diperoleh yaitu 0,1378 dengan kategori rendah. Selain itu Peningkatan self efficacy peserta didik dapat dilihat dari angket yaitu hasil perhitungan skor menunjukkan 40% peserta didik mempunyai self efficacy yang sangat tinggi, 47% peserta didik pada kriteria tinggi, dan 13% pada kriteria cukup tinggi.

The method used was Research and Development (R&D) with Borg and Gall development model. It was implemented at the eleventh grade students of Science Islamic Senior High of Darul Hikmah Pekanbaru. Student worksheet was considered appropriate when it meet validity and reliability aspects. Validity was seen from validity result of using validation sheet.

Practicality test was done to 3 teachers and it was obtained 87% result that it was on very practical category. Response of 15 students that was seen from questionnaire result was 81% and it was on very practical category. The increase of student self efficacy could be known through the calculation of N-gain This is an open access article under CC-BY-SA license (https://creativecommons.org/licenses/by-sa/4.0/) based on pretest and posttest results. N-gain mean was 0.1378 and it was on low category. Moreover, the increase of student self efficacy could be known from questionnaire, it was obtained that 40% students had very high criterion of self efficacy, 47% students had high criterion, and 13% students had adequate criterion.
