PENINGKATAN KETERAMPILAN PROSES SAINS DAN HASIL BELAJAR MELALUI PEMBELAJARAN BERBASIS LABORATORIUM

Abstract

The aims of research are : (1) to design laboratory based learning, (2) implementation of laboratory based learning, (3) evaluation systems, (4) increasing of achievement and science process skill through laboratory based learning.This research used classroom action research, which is done by SMP Negeri I Pekalongan. This research was done into three cycles, they are cycle I, cycle II and cycle III. The data was collected by observation and test, it was analyzed by quantitative research.The results of research are: (1) lesson plan syntax was arranged by laboratory based learning model into three activities, they are pre activity, main activity and post activity; (2) implementation of laboratory based learning increase student’s science process skill.: (3) evaluation system used multiple choice and essay test, instrument validity test at cycle I, II, and III is about 0, 64 and reliability is 0, 71
