Improving Students’ Creativity Through Sharing and Jumping Task in Mathematics Lesson Study Activity

Abstract

The sharing and jumping task in the learning process are unfamiliar to use in schools in Indonesia. Almost, all schools in Indonesia use student worksheets as sharing tasks without using jumping tasks. Even though jumping task can provide opportunities for students to think higher. This study aims to describe the increase in junior high school students’ creativity in solving mathematical problems through sharing and jumping task. This research is a case study conducted collaboratively among teachers and lecturers in lesson study activities. The results of this study indicate that students can improve their abilities including: (1) communication, (2) collaboration, and (3) critical thinking through sharing task activities. Besides that, students can increase their creativity in solving mathematical problems through jumping task activities. Each student produces different answers. The different answers produced by them in solving problems include three creative indicators, namely (1) fluency, (2) flexibility, and (3) novelty.
