Pengembangan LKPD Berorientasi Group Investigation Untuk Melatihkan High Order Thinking Skills Pada Materi Laju Reaksi

Development of Student Worksheet With Group Investigation to Train Student High Order Thinking Skills on The Reaction Rate 

Abstrak

Penelitian ini bertujuan mendeskripsikan kelayakan LKPD berorientasi group investigation untuk melatihkan HOTS peserta didik pada materi faktor-faktor yang memengaruhi laju reaksi. Metode penelitian yang digunakan yaitu Research and Development (R&D) oleh Borg & Gall dibatasi sampai tahap uji coba terbatas. Kelayakan ditinjau berdasarkan 3 aspek yaitu validitas, kepraktisan, dan kefektifan. Validitas ditinjau melalui validitas isi dan validitas konstruk. Kepraktisan ditinjau dari angket respon peserta didik setelah penggunaan LKPD didukung dengan aktivitas peserta didik saat menggunakan LKPD. Keefektifan ditinjau melalui tes HOTS peserta didik yang diujikan kepada 16 peserta didik SMAN Mojoagung menggunakan model kooperatif tipe group investigation. Analisis data menggunakan deskriptif kuantitatif. Hasil penelitian pengembangan LKPD dinyatakan sangat valid dengan persentase validitas isi sebesar 88,7 % dan validitas konstruk sebesar 90,9 %. LKPD yang mendapatkan respon positif dinyatakan sangat praktis dengan presentase sebesar 86,2%-100% dan didukung oleh aktivitas relevan peserta didik lebih besar daripada aktivitas yang tidak relevan. Kemampuan HOTS peserta didik diolah dengan N-gain dilihat dari nilai pretest dan posttest. Hasil dari n-gain peserta didik yang mendapat kategori sedang sebesar 6% dan kategori tinggi sebesar 94%. Sedangkan ketuntasan klasikal sebesar 100%. Berdasarkan hasil validitas, kepraktisan, dan keefektifan, maka LKPD dapat dinyatakan layak digunakan.

Abstract

This study aims to describe the feasibility of a group investigation-oriented student worksheets to train HOTS on the factors that influence reaction rates. The research method used Research and Development (R&D) by Borg & Gall which was limited to a limited trial stage. Feasibility is reviewed based on 3 aspects, validity, practicality, and effectiveness. Validity is observed of content validity and constructs validity. Practicality is observed from the student response questionnaire after using student worksheets and supported by student activities when using student worksheets. The effectiveness was reviewed through the HOTS test by 16 students on SMAN Mojoagung using investigation group of cooperative learning model. Data analysis using quantitative descriptive. The results of this study could be very valid classified the percentage of student worksheets validity included 88.7% content validity and 90.9% construct validity. The developed student worksheets received a positive response stated to be very practical with 86.2% -100% percentage and supported by the relevant activities of students, which were greater than irrelevant activities. HOTS of students processed with N-gain can be observed by the pretest and posttest scores. The result of the n-gain score is 6% of students classified as moderate category and 94% of students classified as a high category. While classical completeness is 100%. Based on the results of validity, practicality, and effectiveness, student worksheets can be declared fit for use.
