Improvement of mathematics learning activity through lesson study

Abstract

The purpose of this lesson study was to improve learning activities of Mathematics instruction. Learning activities to be improved is the theory of probability. There are three phases on this lesson study, PLAN, DO and SEE. In PLAN cycle, the researcher organizes chapter design and lesson plan. In the Do cycle, the lesson plan was implemented in instruction using Think-Pair-Share model. Students are thinking individually before they were paired in groups. The teaching process is organized in two sequence classes. In the first lesson, the learning process was quite conducive, but it still needed some improvement. In cycle SEE, based on the observation of the first lesson, teachers are suggested to use more concrete-case examples to build students' understanding of concepts for the next lesson. The teachers should ask more questions and pay attention to students who are less active during the class. The last recommendation is that students should analyse assignment independently before posing criticisms and providing suggestions to others. The second lesson shows that students are more active compared to the first lessons. Students have more relaxed learning atmosphere. They are more assertive and involved in whole class activities. The students are more confident to ask questions, give objections, and make some corrections.
