PENGEMBANGAN LKPD BERBASIS CONCEPTUAL ATTAINMENT UNTUK MENINGKATKAN PEMAHAMAN KONSEP DAN KETERAMPILAN PROSES SAINS PADA MATERI KESEIMBANGAN DAN DINAMIKA ROTASI DEVELOPMENT OF STUDENT WORKSHEET WITH CONCEPTUAL ATTAINMENT METHOD TO IMPROVE CONCEPTS UNDERSTANDING AND SCIENCE PROCESS SKILLS IN EQUILIBRIUM AND ROTATIONAL DINAMICS

Abstract

Abstrak
Tujuan penelitian adalah untuk: (1) menghasilkan LKPD berbasis Conceptual Attainment, (2)
mengetahui peningkatan pemahaman konsep, (3) mengetahui peningkatan keterampilan proses sains.
Penelitian ini merupakan penelitian pengembangan dengan desain Four D Models (define, design, develop,
dan disseminate). Produk yang dikembangkan diujicoba di kelas XI SMA Negeri 1 Magelang, 20 peserta
didik untuk uji terbatas dan 33 peserta didik untuk uji lapangan. Hasil penelitian: (1) dihasilkan LKPD
berbasis Conceptual Attainment yang layak digunakan dilihat dari penilaian kesesuaian tata bahasa dan
tampilan PA 96,97%, kesesuaian pembelajaran berbasis Conceptual Attainment PA 95,24%, dan kesesuaian
pembelajaran untuk meningkatkan keterampilan proses sains PA 95%, ketiganya dalam kategori sangat
baik. Kecenderungan respon peserta didik terhadap aspek penilaian LKPD adalah setuju, dengan persentase
uji terbatas 78% dan uji lapangan 89%. (2) Peningkatan pemahaman konsep uji terbatas 0,56 dan uji
lapangan 0,50, keduanya dalam kategori sedang. (3) Peningkatan keterampilan proses sains tidak signifikan
pada uji terbatas maupun pada uji lapangan dengan range 0,1-0,3.

Abstract
This research aims were to: (1) produce Conceptual Attainment student worksheet, (2) know concepts
understanding improvement, (3) know science process skills improvement. This was a development
research by using 4-D models (define, design, develop, and disseminate). The development product was
tested in grade XI SMA Negeri 1 Magelang, 20 students for limited test and 33 students for field test. The
research results: (1) were produced student worksheet based on validator’s score from language structure
and design PA 96.97%, appropriate learning with Conceptual Attainment method PA 95.24%, and learning
to improve science process skills PA 95%, which all aspects got the best category. Almost students agreed
to the worksheet with presentation 78% for limited test and 89% for field test. Concepts understanding
improvement based on Normalized Gain (g) were 0.56 for limited test and 0.50 for field test. Science
process skills improvement weren’t significant for all the test with range 0.1-0.3.
