PENGEMBANGAN PERANGKAT PEMBELAJARAN KIMIA BERBASIS PROYEK (PROJECT BASED LEARNING) UNTUK MENINGKATKAN KETERAMPILAN PROSES SAINS PESERTA DIDIK SMK NEGERI 1 TALIWANG

Abstract

Science process skills are important things that need to be developed for the sake of
future students. However, this has not been facilitated properly
in the learning process in class. This research aims to develop
valid project-based learning chemistry tools,
practical, and effective way to improve the science process skills of SMK students.
This Research and Development (R & D) adapts the 4-D model consisting of
define, design, develop, and disseminate. The study population was 249 participants
class X students of SMK Negeri 1 Taliwang with a sample of 24 class students
X Machining Engineering using purposive sampling technique. Feasibility testing
the product uses a validation test by two expert validators in the form of a validation sheet
for syllabus, RPP (Learning Implementation Plan), LKPD (Worksheet
Learners), and science process skills instruments. Results of data analysis
shows that the learning device is in the validity category
very high. Testing the practicality of the learning process using sheets
observation of the implementation of learning, teacher response questionnaires, participant response questionnaires
educate. The results of the data analysis show that the learning devices are at
practical category. The results of data analysis show that the learning process
using the developed learning tools proved to be effective
improve the science process skills of SMK students. And there is influence
use of project-based chemistry learning tools for skills
science process. The conclusion in this study is a chemistry learning device
project-based developed very valid, practical, and effective in
improve the science process skills of SMK students.
