Implementation of PCT (Paper Chromatography Techniques) Practicum Media on Student Learning Outcomes on Mixed Separation Materials

Abstract

This study aims to see the effect of implementing PCT (Paper Chromatography Techniques) practicum media on student learning outcomes on mixed separation materials. This research is a type of research and development (Research and Development). Based on the results of the study, it is known that there has been an increase in student learning outcomes after using PCT (Paper Chromatography Techniques) Practicum Media, this can be seen from the comparison of students' pretest and posttest scores. The average pretest score of students before using PCT practicum media was 50.84 while the average posttest score of students after using PCT media was 81.79. The results of the students' pretest and posttest were tested for gain or gain score by comparing the students' average pretest and posttest scores. The gain score obtained is 0.62 with the "medium" category.
