Abstract

The investigation was a research and development using ADDIE method which aims to get a standardized project-based chemical practicum guidedbook on solubility and solubility (Ksp) products. Population of the study was all ofthe Unimed chemistry lecturers,chemistry teachers and students of grade XI IPA 14 Medan, and all of the practical guide books publishedin Medan. Sampling was selected by purposive sampling technique which consists of 3 chemical practicum guided bookspublished by three companies called A, B and C chemistry laboratory guide books; 2 chemistry lecturers; 2 chemistry teachers; and grade XI IPA-1 as experiment group1 and IPA-4 as experimental group 2. Average standardized scores of practicum guided books developed = 3.78 was higher than the practicum guidedbooks A = 3.14; B = 3, 32; and C = 3.11 respectively. Percentage of normalized gain test of the practicum guided book developed in the experimental group 1 was higher than the experimental group 2 i.e 88.00% > 80.00%. Post-test scores on the right side at α = 0.05, obtained t-count. = 6.4 > t-tab. = 1.67. This shows that the project-based chemistry practical guided book developed is in accordance with BSNP standards and can be used in high schools..
