Abstract

Problem solving skills in mathematics is the essential thing for the students to apply that skill in real life. The learning model that can be implemented to improve problem solving skills is Malcolm’s Modeling. The objectives of this research were : (1) to measure problem solving skill of the students who was taught by Malcom’s modeling based on KWL thinking strategy towards the mastery learning; (2) to compare the students on problem solving skills who received Malcom’s Modeling based on KWL Thinking Strategy and expository learning model in the chapter of Scientific Notation. The population of this research were students of seventh grade of Tainan Municipal Jincheng Junior High School in the academic year of 2016/2017. By simple random sampling technique, 705 class was selected as the experiment class and 711 as the control class. The data were collected by using some instruments, they were test and documentation. Data analysis used SPSS software and excel for t-test and proportion test. The results of the research showed that : (1) Malcolm’s Modeling based on KWL Thinking Strategy gained good result to the score of the students. It was seen from the proportion test that 86% of the students in experiment class were passing mastery learning clasically (2) the problem solving skill of the students who received Malcom’s Modeling using KWL Thinking Strategy was better than that skill of the students who received expository learning model.
