VALIDITY OF COMPUTER-BASED ELECTROLYTE FISHER GAME TO DEVELOP PROBLEM-SOLVING SKILL OF STUDENTS IN ELECTROLYTE AND NONELECTROLYTE SOLUTION

Abstract

 The aim of this research was to get a valid computer-based Electrolyte Fisher game to develop problemsolving skill of students on electrolyte and nonelectrolyte solution topics so it could be used in learning
activity. The type of this research was development research by using 4D model with four stages including
define, design, develop, and disseminate, but the stages carried out in this research only until development
stage. Validity was determined by two chemistry lecturers and one chemistry teacher. Research results
proved that Electrolyte Fisher game was valid based on content validity percentage of 84.44% and construct
validity percentage of 85.37%. There were three criteria assessed in content validity including the
correctness of concepts in matter obtaining a percentage of 86.67%; the suitability of matter with learning
objectives obtaining 86.67%; and the suitability of game with problem-solving skill component obtaining
80.00%. There were two criteria assessed in construct validity, namely the suitability of game with learning
media requirements which included nine aspects obtaining percentage of 87.78% and the suitability of
display quality in game which included three aspects obtaining 82.96%. Based on results of this research
showed that the computer-based Electrolyte Fisher game to develop students’ problem-solving skill was
declared valid.
Key words: electrolyte fisher game, problem-solving skill, electrolyte, and nonelectrolyte solution.
