The Use of Digital Algebra Block Media on The Material of Calculating Operations of Algebraic Forms in Class VII Mathematics Learning to Improve Learning Outcomes

Abstract

The use of technology in the context of education is an urgent need to improve the effectiveness of learning in junior high schools. This study originated from the unsatisfactory learning outcomes of algebraic form operation material, most students obtained scores below the minimum learning completeness standard. This study aims to determine whether the use of digital algebra block media in algebraic form operation material can improve the learning outcomes of junior high school students and to find out how to improve the learning outcomes of junior high school students after using digital algebra block media in learning mathematics on algebraic form operation material. This research is a Classroom Action Research conducted in 2 cycles, each cycle held 1 meeting. The subjects in this study were class VII.5 students totalling 40 students.  Data collection techniques using teacher observation sheet instruments, students and essay questions. The results of observations of teacher activity in cycle I were 73.33%, cycle I student activity in learning reached 61.56% and using digital algebra block media reached 64.38%, and in cycle II teacher activity increased by 93.33% and in learning reached 73.56% and using digital algebra block media reached 80.94%. Likewise, the average student learning test at the pre-cycle stage was 68.18, in cycle I it was 74.78 with a percentage of classical completeness of 72.5% and in cycle II the average student learning test increased to 84.08 with classical completeness reaching 90% so that the research can be said to be successful because it has reached the expected completeness. By using digital algebra block media, not only makes the operation of algebraic forms more interesting and real, but also students can understand abstract objects into concrete objects. The findings of this study indicate that digital algebra blocks can improve student learning outcomes in the material of algebraic form operations in mathematics learning for students in class VII.5 SMP.
