Pengembangan Lembar Kerja Peserta Didik Berorientasi Inkuiri Terbimbing untuk Melatihkan High Order Thinking Skills pada Materi Laju Reaksi

Development of Student Worksheet with Guided Inquiry to Train High Order Thinking Skills on the Reaction Rate Materials

Penelitian ini bertujuan mendeskripsikan kelayakan LKPD berorientasi inkuiri terbimbing untuk melatihkan HOTS pada materi laju reaksi. Metode penelitian yang digunakan yaitu Research and Development (R&D) oleh Borg & Gall dibatasi sampai tahap uji coba terbatas. Uji coba terbatas dilakukan pada 33 peserta didik kelas XI IPA 1 SMAN 1 Gedangan Sidoarjo. Kelayakan LKPD berorientasi inkuiri terbimbing ditinjau dari aspek validitas, kepraktisan, dan keefektifan. Aspek validitas yang meliputi validitas isi dan validitas konstruk menunjukkan bahwa LKPD yang dikembangkan sangat valid dengan persentase masing-masing 93% dan 89,70% untuk masing-masing kriteria. Aspek kepraktisan ditinjau dari hasil angket respon peserta didik mendapatkan persentase sebesar 94-100% dengan kategori sangat praktis dan didukung oleh aktivitas relevan peserta didik lebih besar daripada aktivitas yang tidak relevan. Aspek keefektifan ditinjau melalui tes ranah pengetahuan dan HOTS. Hasil tes ranah pengetahuan dan HOTS diuji dengan Paired Sample T-Test masing-masing mendapatkan nilai Sig. (2-tailed) sebesar 0,000 yang berarti terdapat perbedaan ranah pengetahuan dan HOTS antara sebelum dan sesudah LKPD diterapkan. Selain itu, keefektifan juga ditinjau dari n-gain. Hasil n-gain pada tes ranah pengetahuan menunjukkan peserta didik dengan kriteria tinggi sebesar 84,84% dan kriteria sedang sebesar 15,16%, serta  hasil n-gain pada tes HOTS menunjukkan peserta didik dengan kriteria tinggi sebesar 93,93% dan kriteria sedang sebesar 6,07%. Sehingga dapat disimpulkan bahwa LKPD berorientasi inkuiri terbimbing dinyatakan layak dan dapat melatihkan HOTS peserta didik.

This study aims to know the feasibility of the students' worksheets with guided inquiry to train high-order thinking skills on the reaction rate materials. The research method used is Research and Development by Borg & Gall until the limited trial stage. The limited trial was conducted on 33 students in class XI IPA 1 SMAN 1 Gedangan Sidoarjo. The student worksheets with guided inquiry are feasible based on validity, practicality, and effectiveness aspects. Aspects of validity include content validity and construct validity indicate that the student worksheet developed is very valid with a percentage of 93% and 89.70% for each criterion. Practicality observed from the results of the student response questionnaires gets a percentage of 94-100% with a very practice category and supported by more relevant student activities than irrelevant activities. The effectiveness is seen from the results of the knowledge domain test and HOTS with Paired Sample T-Test each getting a Sig. (2-tailed) of 0.000 which means the difference in the average value between before and before the student worksheet was given. In addition, the effectiveness is also viewed from the n-gain. The n-gain results on the knowledge domain test showed 84.84% of students with high category and 15.16% of students with medium category, and the n-gain results on the HOTS test showed 93.93% of students with high category and 6.07% of students with medium category. So, it can be stated that the student worksheet with guided inquiry is declared feasible and can train students' HOTS.
