Prototipe buku ajar fisika dasar reflektif-integratif berbasis problem solving untuk meningkatkan pengetahuan metakognisi

Abstract

This study aims to evaluate the validity and effectiveness of the reflective-integrative basic physics textbook prototype based on problem-solving to improve metacognition knowledge. This research is a quasi-experimental study with one group pretest-posttest design in 25 physics education students of FPMIPA IKIP Mataram. Descriptive and statistical analysis using the n-gain equation and paired samples test was conducted to evaluate the validity and effectiveness of the product. Product validity was assessed by two competent experts using validation sheets and analyzed descriptively, while product effectiveness was measured after learning using essay test instruments that were analyzed descriptively and statistically using paired samples test. The results showed that the reflective-integrative basic physics textbook prototype based on problem-solving was valid  (3.38) and reliable (0.97), while declarative knowledge (n-gain = 0.58), procedural knowledge (n-gain = 0.53), and conditional knowledge (n-gain = 0.56) was increased after learning in the medium category. Statistical test results showed that the reflective-integrative basic physics textbook prototype based on problem-solving had a significant effect (p <0.05) on the students' metacognition knowledge. Based on these findings it can be concluded that the reflective-integrative basic physics textbook prototype based on problem-solving was valid and effective to improve students' metacognition knowledge.
