Lack of innovative learning media that is interesting, practical and easy to use in learning such as listening to lesson modules or seeing powerpoint shows used by teachers, thus causing learning to be ineffective, unattractive, and slow to understand, this results in a lack of understanding of mathematical concepts. Because of this, researchers are trying to develop an interesting and interactive learning media. This type of research is development research that aims to produce learning media on Android-based discovery learning apps that are feasible to use and to improve understanding of mathematical concepts of seventh-grade students. The method used is the ADDIE method. Which consists of 5 stages, namely Analysis, Design, Development, Implementation, and Evaluation. Data analysis was carried out by normality, homogeneity, n-gain test, and right-sided t test. The results of this study can be concluded that (1) the results of the percentage of media expert validation amounted to 80.26%, material experts 86.36% and student response responses of 87.16% with the criteria of each very good. (2) the results of the n-gain test obtained that there is an increase in understanding of mathematical concepts of students who use learning media on Android-based discovery learning applications. (3) data from the field shows that student learning outcomes that obtain learning media android apps based on discovery learning are better than students who use conventional learning

The adequate learning resources as support for student learning activities was one of the factors supporting the learning process successful. The use of textbooks as a source of learning did not support thinking activities, especially students' mathematical reasoning abilities. The textbooks so far only emphasize the understanding of the concept while the students' mathematical reasoning abilities were less noticed. This research intends to develop student worksheets that are valid, practical and effective in developing mathematical reasoning abilities and can be accessed via the internet. The research model used is Research and Development (R & D). To see the effectiveness of the product carried out an experiment. The results showed that through the learning assisted students worksheets that integrated the internet, the average of students' mathematical reasoning abilities were increased.

The objective of this study is to determine the effect of cognitive style on students’ mathematical problem-solving ability. This study used the survey method with a quantitative approach. One class consisting of 32 students was selected by purposive sampling for the study sample. A total of 17 students have a field-dependent (FD) cognitive style, while 15 other students have a field independent (FI) cognitive style. GEFT and mathematical problem-solving ability test instruments were used to collect research data. Data were analyzed using Pearson Product Moment correlation test and a simple regression test. The research results found that there is a strong positive relationship between cognitive style and students’ mathematical problem-solving ability, indicated by correlation coefficient r = 0,636. In addition, cognitive style has an effect on students’ mathematical problem solving ability of 40,5% through a linear relationship Ŷ = 3,703 + 0,512X.
