In traditional teaching, many teachers often ignore the process of students' knowledge exploration, devote themselves to instilling knowledge to students in a short time, and then adopt the sea of questions tactics. Such teaching is only limited to the stage of telling students what "variance" is and how to use it, and ignores the birth process and meaning of "variance". The purpose of this research is to see the differences in classes that use dynamic mathematics software and traditional classes. The method in this research is descriptive qualitative.

Learning tools developed in this development research is students’ worksheets. The research method used is 4D model, which consists of 4 stages, namely define, design, develop, and disseminate. The results of worksheets’ validation by experts were 4,05 for the layout design and 4,19 for the content (both were categorized as valid).

The purpose of this study was to describe the increase in mathematical problem-solving abilities and students' responses during the learning process by applying a problem-solving approach with metacognitive strategies. This research is a classroom action research consisting of 3 cycles. The instrument used is a test of mathematical problem-solving skills and student response questionnaire. The results of the study concluded that the ability of mathematical problem-solving in the application of problem-solving approaches with metacognitive strategies has increased.

This study aimed to improve student’s problem-solving abilities of tangent circle equations using discovery learning. This research was done in class XI IPA 4 SMA N 1 Palembang. This research method is used Classroom Action Research with discovery learning models. The instrument is used test instrument in the form of an evaluating matter of the tangent circle equation in the description form and the observation sheet for observation of the learning activity of the students.

This research is motivated by the low student mathematics learning outcomes. The reason is the lack of full delivery of lessons and students have not fully understood the material. One alternative to overcome this problem is to implement a complete learning model with peer tutoring methods.

The purpose of this study was to determine the correlation learning styles and learning activeness towards students' mathematics learning outcomes. This study was a correlation study with all students of class VIII SMP II Luqman Al-Hakim Batam as the population, they were 154 students. The sampling technique uses a purposive sampling technique.

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.

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.
