The development of mathematical learning material based on model-eliciting activities (MEAs) approach to improve mathematical problem-solving skill of students of grade X of Senior High School Padang

Abstract

Mathematical problem solving skill is a very important ability in mathematics learning. This skill is used in learning and solving problems. In fact, problem-solving skill of students can be enhanced. Students should get the opportunity to develop their skill in problem solving. One of the efforts to improve problem-solving skill of students is to develop mathematics learning material based on Model-Eliciting Activities (MEAs) approach. The purpose of this study is to produce mathematics learning material based on MEAs approach, which are valid, practical and effective. This developmental research uses the Plomp’s model consisting of three phases: preliminary, prototyping, and assessment stage. Subjects of this study were students of grade X of Senior High School Padang state. The results of data analysis from validity of the instrument was showed that mathematics lesson equipment based on MEAs approach has fulfilled valid criteria in terms of content and construct. The lesson equipment has been considered as practical in terms of feasibility, convenience, and time because they can be applied in mathematics learning activities. The lesson equipment has also been effective since they can enhance problem solving skill. Based on these results, it can be concluded that mathematics lesson equipment based on MEAs approach, which were implemented to students of grade X in the first semester was valid, practical, and effective.
