Improve the ability of understanding mathematics and confidence of elementary school students with a contextual approach using VBA learning media for Microsoft Excel

Abstract

The main problem of this research is the lack of students understanding the ability and mathematical self-confidence for mathematics learning in elementary school students in Indonesia. Lack of students understanding of mathematics is caused by the learning process in school. Teachers still use conventional learning in the learning process. Also, the basic skills aspects of students also affect the ability of math skills. Furthermore, the learning process with a contextual approach assisted by VBA Learning Media (Visual Basic Application for Excel) gives positive influence on students both regarding mathematical understanding and self-confidence. The data processed in this study is from the post-test score. This score arises from both the experimental class group and the control class group. Then, the data processed using SPSS 22 and Microsoft excel. Data were analyzed using the t-test statistic. The final result of this study concludes achievement and improvement of mathematical understanding ability and Self Confidence students learning with contextual approach supported by VBA (learning media Visual Basic Application for Excel) are better than students who get conventional learning.
