Application of TTW (Think-Talk-Write) learning model using pictorial riddle worksheet to improve students's conceptual undertstanding abilities

Abstract

This study aims to see an increase in students' ability to understand concepts after applying the TTW (Think-Talk-Write) learning model assisted by Pictorial Riddle-based Student Worksheet. The research method used is quasi-experimental. There were two experimental classes, namely the modeling class and the implementation class. The sample of this study was 24 students of class XI Science 4 as modeling class and 23 students of class XI Science 3 as implementation class in Prambanan High School 1 Yogyakarta. Data collection techniques were carried out by Pretest and Post-Test. Data were analysed using the Wilcoxon test and descriptive analysis to determine the N-Gain score. The results showed that the TTW (Think-Talk-Write) learning model assisted by Pictorial Riddle-based Student Worksheet could improve students' conceptual understanding abilities. This is indicated by the value of Asymp Sig. (2-tailed) smaller than 0.05 where 0.046 < 0.05 and the N-Gain score is 0.2061 in modeling class and Asymp Sig. (2-tailed) smaller than 0.05 where 0.003 < 0.05 and the N-Gain score is 0.2775 in implementation class. The conclusion is this model has an effect on the students' ability to understand concepts with a low increase category.
