VALIDITY OF PROBLEM-BASED SCIENCE PRACTICAL INSTRUCTIONS

Abstract

This research aims  to test the level of validity of problem- based  science practicum  instructions  aimed  at  class  VIII SMP/MTs  students  in  odd semesters.  The  problem-based approach was chosen because it was proven to be effective in improving students' critical thinking and problem solving skills.  This  research  uses  part  of  the  4D  method  which consists of definition, design and development. The results of  this  research  show  that  the  problem-based  practicum instructions developed are valid, with a validity value of 4.2, which means that the problem-based practicum instructions are included in the valid criteria. It  is hoped that the final product resulting from this research can be a reference for teachers  in  teaching  science  using  a  problem-based approach,  so  that  it  can  improve  the  quality of  science learning in schools.
