PENGEMBANGAN PENUNTUN PRAKTIKUM KIMIA BERBASIS PENDEKATAN SAINTIFIK PADA MATERI LAJU REAKSI UNTUK SISWA KELAS XI IPA DI SMA ADISUCIPTO PONTIANAK

Abstract

Low students’ understanding of reaction rate factors had occurred in grade XI of SMA Adi Sucipto Pontianak as a result of lack of learning resources. Therefore, this study aimed to develop an experiment guidebook based on a scientific approach to assist students on comprehending factors influencing reaction rate. Modified 4D Thiagarajan’s model of Research and Development (R&D) was carried out, in which the guidebook was evaluated regarding its feasibility including validity, effectiveness, and practicality. The validity value judged byexperts of mediawas 87.64% (very valid). In addition, the practicality level measured by responses from both teacher and students were 100% (very practical) and 98.14% (very practical), respectively. The use of the guidebook in classroom was effectively improved students’ learning outcome as the N-gain value was 0.89 (very high). As a conclusion, the resulted experiment guidebook based on a scientific approach was feasible to be used as a learning resources on reaction rate subject in grade XI of SMA Adisucipto Pontianak.Keywords: Chemical Practic Guides, Scientific Approach.
