The development of mathematical problem based on Higher Order Thinking Skill (HOTS) on comparative material by implementing PBL and its effect on the teacher’s creative thinking skill

Abstract

Abstract Assessing both learning process and achievement is a pedagogical competency in which it refers to an ability that must be possessed by the teacher. The learning done by teacher is intended to maximize the students’ higher order thinking skills, that is why the assessment is required to measure their higher order thinking skills. This research was carried out to study the teacher’s creative thinking skill and the implementation of problem-based learning to improve teacher’s creative thinking skill in creating mathematical problems based on higher order thinking skill (HOTS) through a comparative research. The method used was mixed method combining quantitative and qualitative research methods. 64 respondents were selected as the subject of this research, then they were divided into two classes, an experimental class which involved 32 teachers and a control class which consisted of 32 teachers. This research revealed that there was a significant difference found on the independent t-test from the post-test. Data analysis showed that t-value taken from post-test was sig. 0,000< 0.05, it proved significant. Therefore, there was an effect of the implementation of problem-based learning in which it was able to improve the teachers’ creative thinking skill in creating mathematical problems based on higher order thinking skill.
