Abstract

This research supported by the lack of student’s mathematical understanding ability, and the need for the development of linear programming material for students.The purposes of this research are: to  describe the  characteristics of linear programming material written with problem-based learning model, and assess  the quality of material considered from validity, practicality, and effectiveness.The research used quantitative  and qualitative approaches, with research and development method, in form of Dick and Carey’s design. Research was conducted at one of senior high school in Bandung. The instruments used are: validation’s sheets, the mathematical understanding test, observation sheets, and questionnaire. According to the data processing and analysis of the development of material, researcher have two conclusions. The first conclusion, characteristic of material developed was:  based on the curriculum 2013 standard with a KI-1 not specified in teaching materials and some KI-2 not all included in material, the presentation of material developed according to a problem-based learning model, and equipped with a problem, examples, exercise about, and evaluate compiled based on an indicator of mathematical understanding ability. The second conclusions, instruction materials developed was valid, practical, and effective.

Abstract

Abstract There are still problems in learning mathematics, many students consider learning mathematics as a difficult lesson, especially because of the lack of interest in learning mathematics. One of the reasons is the low ability to understand mathematical concepts and students' interest in learning. To overcome this, the researcher applies a problem-based learning model, namely Problem-Based Learning (PBL) in the hope of increasing students' interest and understanding of concepts. The purpose of this study is to measure the ability to understand mathematical concepts and learning interests of participants and analyze the ability to understand mathematical concepts reviewed from their learning interests through arithmetic series material. The study uses a quantitative method with a One-Shot Case Study design, which involves one class (30 people) as the research subject. The research instrument consisted of a description test to measure understanding of mathematical concepts and a questionnaire to measure learning interest. The results of the study showed that students' ability to understand mathematical concepts exceeded the KKTP with an average score of 87.83. 60% of students' learning interest was classified as moderate learning interest, and the results of the ability to understand mathematical concepts with "high" learning interest were 6 students with an average score of 94.16, the ability to understand mathematical concepts with "medium" learning interest as many as 16 students with an average score of 89.72 and the ability to understand mathematical concepts with "low" learning interest as many as 6 students with an average score of 75.80.
