Abstract
The lack of students' mastery of decimal fractions has become a current issue among researchers. The comparisin of decimal fraction values was still an obstacle for students. The use of learning media in this study is the Computer Assisted Learning Media and Decimal Board can be a solution to these problems. This study aimed to describe the increase of elementary students’ concept mastery on decimal fractions subject matter. Descriptive-quantitative method with pre-test and post-test was carried out to achieve the research objectives. The subjects in this study were the 4th grade students (22 students) in the East Lombok area. The students' concept mastery was measured using a multiple-choice test instrument of 10 items. The research data were analyzed descriptively and statistically using paired sample t-test. The results showed that students' concept mastery increased after learning (pre-test: 54.5%; post-test: 77.27%). The results of statistical tests using the paired sample t-test also showed that students' concept mastery had increased significantly after learning (p < 0.05). Based on the results of the study, it can be concluded that learning using Computer Assisted Learning Media and Decimal Boards can improve elementary school students' concept mastery on decimal fractions subject matter.
Highlights
Students' understanding of learning content must be the goal and expectation of all teachers
The aims of this study was to find decimal fractions, sort and compare decimal fractions, summarize and subtract decimal fractions, and solve problems related to decimal fractions
This study only focuses on decimal fractions, so it is necessary to carry out research on other materials to obtain consistency in the effectiveness of using learning media in the future
Summary
Students' understanding of learning content must be the goal and expectation of all teachers. In order to build or understand the concept of a learning content it is necessary to have strong knowledge. According to Beetlestone (2013) knowledge is the information needed to run a task or to understand a concept. According to Irwin, Putt, Resnick et al, Stacey et al, Sackur-Grisvard & Léonard, students often have difficulty in mastering decimals and common and persistent misunderstandings, with difficulty persisting into adulthood (Adams et al, 2014). This happens because of the lack of mastery of students' conceptions of decimal fractions. Because concept is an element of cognition that helps us simplify and summarize information
