Abstract

The purpose of this research is to produce valid, effective, and practical textbooks. In the short term, it aims to produce valid and practical teaching materials for linear algebra courses. Validity based on the relevance of the expected competencies i.e. 21st century competencies. Practicality is measured by the use of teaching materials in classroom learning. This study used a development research design, followed by four steps: 1) initial research, 2) prototyping, 3) summative evaluation, 4) reflection and documentation. In our initial research, we analyzed the need for teaching materials for the Information Systems study program, the reason being that students really needed linear algebra teaching materials that had applied concepts that were described visually that were easy to understand by students. In the prototyping stage, we write teaching materials according to the needs analysis. The prototype was discussed with experts, revised after summative evaluation and implemented during lecture meetings. The result is the final product in the form of teaching materials used during reflection. Our systemic documentation was written according to the established research framework. Finally, a valid, practical linear algebra teaching material has been produced

Abstract

One of the factors to the lack of success in the mathematics learning process is that the teacher does not innovate in applying the media in learning. In general, teachers at Budi Agung Private High School still apply conventional media so that students become passive and less interested in mathematics. This has an impact to the low student learning outcomes. Therefore, innovation in Adobe Flash-based learning is needed. The purpose of this study was to test the effectiveness of the use of Adobe Flash learning media on students' mathematics learning outcomes at Budi Agung Private High School, Medan. This study uses a quasi-experimental design. Data collection techniques consist of unstructured interviews, observation, documentation, and tests. The data analysis techniques used are the Liliefors test to test the normality of the data, the Levene test to test the homogeneity, the independent sample test, and the party test through one sample t-test to test the hypothesis. The population in this study were classes X-A and X-B SMA Private Budi Agung Medan, totaling 72 students, consisting of 35 students in the experimental class and 37 students in the control class. The results of this study were obtained through the results of the students' final test (post-test). The average post-test result of the experimental class students using Adobe Flash was higher than the control class using conventional methods, with namely the experimental class was 75.1 and the control class was 55.73. And based on the results of the t-test, it was obtained that tcount > ttable, namely tcount = 5.072 and ttable = 1.997 with a significant level of 5% from hypothesis testing Ha was accepted and H0 was rejected, which means that there is an influence on students' mathematics learning outcomes through Adobe Flash-based Learning media

Abstract

Cognitive conflict is a condition where students encounter new experiences that are not neatly arranged in their cognitive structure. The process of assimilation between old and new concepts in students' cognition. So to hone and improve students' cognitive abilities, it is necessary to have repetition aimed at training students' computational thinking skills which will affect their mathematical mastery. The purpose of this study was to see the effect of cognitive conflict on students' mastery of mathematical concepts. The research method is a case study with a qualitative descriptive and quantitative approach. Learning was carried out to 35 semester II students collaboratively in mastering integral concepts. Pretests are given to determine initial mathematical abilities, then problems are given and solved with computational thinking-based cognitive conflict strategies. The results obtained were very significant for moderate initial abilities, but for high initial abilities it did not affect it, for low initial abilities there was no response. The process that occurs during settlement is very conducive. Post-test results compared to pre-test there is a significant difference
