PENGEMBANGAN VIRTUAL LABORATORY IPA BERPENDEKATAN INKUIRI TERBIMBING MATERI TRANSPORTASI AIR PADA TUMBUHAN UNTUK MENINGKATKAN KEMAMPUAN ANALISIS PESERTA DIDIK KELAS VIII SMP DEVELOPMENT OF VIRTUAL SCIENCE LABORATORY USING GUIDED INQUIRY APPROACH FOCUSING ON PLANT’S WATER TRANSPORTATION ISSUES TO IMPROVE ANALYTICAL ABILITY OF GRADE 8 JUNIOR HIGH SCHOOL

Abstract

Tujuan penelitian ini untuk mengetahui: (1) kelayakan virtual laboratory IPA berpendekatan inkuiri terbimbing materi Transportasi Air pada Tumbuhan untuk meningkatkan kemampuan analisis peserta didik menurut dosen ahli dan guru IPA, (2) respon peserta didik terhadap virtual laboratory IPA berpendekatan inkuiri terbimbing materi Transportasi Air pada Tumbuhan, dan (3) peningkatan kemampuan analisis peserta didik setelah menggunakan media virtual laboratory IPA berpendekatan inkuiri terbimbing. Penelitian ini merupakan penelitian R&D dengan menggunakan model pengembangan 4D. Instrumen yang digunakan dalam penelitian ini berupa berupa lembar penilaian virtual laboratory IPA oleh dosen ahli dan guru IPA, angket respon pesera didik terhadap virtual laboratory IPA, soal pretest-posttest dan lembar kerja peserta didik untuk mengetahui peningkatan kemampuan analisis peserta didik. Hasil penelitian menunjukkan bahwa: (1) virtual laboratory IPA berpendekatan inkuiri terbimbing materi Transportasi Air pada Tumbuhan dinyatakan layak oleh dosen ahli dan guru IPA dengan kategori sangat baik (A), (2) peserta didik memberikan respon yang sangat baik dengan nilai A, dan (3) peningkatan kemampuan analisis peserta didik setelah menggunakan virtual laboratory IPA berpendekatan inkuiri terbimbing berdasarkan perhitungan Ngain score sebesar 0,72 dengan kategori sangat baik.

Kata kunci : virtual laboratory, pendekatan inkuiri terbimbing, kemampuan analisis.

This research was conducted to: (1) determine the eligibility of virtual science laboratory using guided inquiry approach focusing on plant’s water transportation issues based on expert lecturers and science teachers, (2) perceieve student’s response toward virtual science laboratory using guided inquiry approach focusing on plant’s water transportation issues, and (3) obtain the improvement of analytical ability of students after using virtual science laboratory using guided inquiry approach focusing on plant’s water transportation issues. This study was R&D with 4D models. Instrument used in this study is validation sheet of eligibility of expert lecturers and science teachers, student’s response questionnaire form, pre-test and post-test also student work sheet to obtain the improvement of analytical ability of student. The result of this study shown that: (1) virtual science laboratory using guided inquiry approach focusing on plant’s water transportation issues is eligible declared by expert lecturers and science teachers and categorized as very good (A), (2) student’s response to virtual science laboratory is highly positive valued by A, and (3) improvement of student’s analytical ability after using virtual science laboratory using guided inquiry approach is very high with N-gain score of 0,72.

Keywords : virtual laboratory, guided inquiry approach, analytical ability.
