Application of Problem Posing Learning Model to Improve Student Problem Solving on Opportunity Materials

Abstract

The purpose of this study was to improve students' problem-solving skills in the matter of opportunity through a problem
posing learning model in class XI students in the even semester of the 2021/2022 academic year. This research method is
classroom action research that follows the Kemmis and Tanggart model. This study covers 3 cycles where each cycle includes
4 stages, namely planning (planning), acting (implementation), observing (observation), and reflecting (reflection). The
research time was 3 months, from February 2022 to April 2022 with 30 students as research subjects, while data were
collected through tests, interviews, observations, and questionnaires. The results showed that there was a significant increase
in test results in each increasing cycle, namely in cycle I = 78.5; cycle II = 84.7; cycle III = 86, 7 and the results of interviews
conducted concluded that learning mathematics through problem posing learning models is fun for students. This study
concludes that learning mathematics by using a problem posing learning model can improve students' problem solving
abilities.
