Pengembangan Lembar Kerja Peserta Didik Elektronik Berbasis Two Stay Two Stray untuk Melatih Kemampuan Berpikir Analisis pada Materi Pewarisan Sifat

The Development of Electronic Student Worksheet Based On Two Stay Two Stray to Train Analysis Thinking Skills in Inheritance Topic

Penelitian ini bertujuan untuk mendeskripsikan validitas dan efektivitas e-LKPD berbasis TSTS materi pewarisan sifat yang dikembangkan dalam melatih keterampilan berpikir analisis peserta didik. Pengembangan e-LKPD menggunakan metode ADDIE (Analysis, Design, Development, Implementation, dan Evaluation). Validitas e-LKPD ditinjau dari hasil validasi yang dilakukan oleh validator ahli menggunakan instrumen lembar validasi yang berisi beberapa aspek meliputi syarat didaktik, syarat konstruksi, dan syarat teknis. Efektivitas e-LKPD ditinjau dari hasil belajar peserta didik yang diperoleh dari hasil pretest dan posttest, serta ditinjau dari respon peserta didik yang diperoleh dari pengisian angket pertanyaan terbuka oleh peserta didik setelah mengikuti pembelajaran menggunakan e-LKPD yang dikembangkan. Uji coba dilakukan secara terbatas pada 16 peserta didik fase F SMAN 3 Sidoarjo. Hasil validasi menunjukkan bahwa e-LKPD berbasis TSTS yang dikembangkan memperoleh skor rata-rata 3,7 dari validator ahli sehingga termasuk dalam kategori sangat layak ketika diinterpretasikan pada kriteria kelayakan. Data hasil belajar peserta didik menunjukkan seluruh peserta didik mengalami peningkatan hasil belajar dengan skor N-gain seluruh peserta didik > 0,70 dan rata-rata skor 0,94 yang artinya memiliki kriteria peningkatan hasil belajar tinggi. Data angket respon peserta didik yang telah dianalisis menggunakan aplikasi NVivo 12 dan menghasilkan visualisasi project map menunjukkan bahwa penggunaan e-LKPD memiliki keterkaitan (relationship) yang positif dengan indikator keterampilan berpikir analisis. Keterkaitan tersebut menyatakan bahwa penggunaan e-LKPD memiliki pengaruh positif dalam peningkatan keterampilan berpikir analisis peserta didik.

This research aims to describe the validity and effectiveness of the TSTS-based electronic student worksheets on inheritance topic that has been developed to train students' analytical thinking skills. The development of electronic student worksheet used ADDIE method (Analysis, Design, Development, Implementation, and Evaluation). The validity of electronic student worksheet was reviewed from the validation results carried out by expert validators using the validation sheet instrument which contains several aspects including didactic, construction, and technical requirements. The effectiveness of electronic student worksheet was seen from the learning outcomes of students obtained from the results of the pretest and posttest, as well as in terms of student responses obtained from filling out open-ended questionnaires by students after participating in learning process using the electronic student worksheet that has been developed. The implementation was carried out in a limited implementation to 16 F-phase students at SMAN 3 Sidoarjo. The results of the validation show that the developed TSTS-based electronic student worksheet obtained an average score of 3.7 from the expert validator so that it was called very decent category when interpreted to eligibility criteria. Student learning outcomes data shows that all students’ learning outcomes were increasing with N-gain score for all students > 0.70 and an average score of 0.94, which means that they have high criteria for learning outcomes improvement. Student response questionnaire data that has been analyzed using the NVivo 12 produces a project map visualization that showed that the use of electronic student worksheet has a positive relationship with indicators of analytical thinking skills. This kind of relationship states that the use of electronic student worksheet has a positive effect on improving students' analytical thinking skills.
