Problem-Based Student Work Sheet Development to Improve Learning Outcomes Mathematics of Elementary School Class Students

Abstract

Efforts to realize an increase in learning outcomes require teaching materials in the form of LKS media that can assist and facilitate learning activities so that they can run successfully. The advantage is obtained when problem solving is carried out by involving awareness of thought processes and self-regulation abilities, thus enabling the building of a strong and thorough understanding of the problem accompanied by logical reasons. The formulation of the problem in this research is; what is the process of developing problem-based student worksheets for improving mathematics learning outcomes, what is the feasibility of developing problem-based student worksheets for improving mathematics learning outcomes, how practical is the development of problem-based student worksheets for improving mathematics learning outcomes, how is the effectiveness of developing problem-based student worksheets for improving mathematics learning outcomes. This research is a type of product development research, the steps adhere to the Borg and Gall theory, namely (1) research and information gathering, (2) research planning, (3) developing initial products, (4) product design validation, (5) product design revision stage I, (6) limited trials, (7) product revision stage II, (8) field trials, (9) Final Product Improvement, (10) Dissemination. Expert validation includes media and language expert validation. Data mining using pretest and posttest. effectiveness and feasibility test using normality test, homogeneity and independent sample t-test. The conclusion from the results of this study is that teachers and students need to develop problem-based student worksheets (LKS) to improve mathematics learning outcomes for fifth grade elementary school students. consists of several parts including 1) compiling a map of the needs of problem- based student worksheets; 2) determine the title of the problem-based student worksheet; and 3) Form design planning, problem-based student worksheets (LKS) are appropriate for use to improve mathematics learning outcomes for fifth grade elementary school students, development of problem-based student worksheets (LKS) is effective for improving mathematics learning outcomes for fifth grade elementary school students.
