The students’ difficulties on understanding the material and the lack of the enthusiasm in learning mathematics, especially in angle measurement material were be the basic reasons for this research. In addition, conventional learning methods that characterized by lectures were still often used by teachers in learning. Therefore, the learning not being more active, effective, and enjoyable. The development of educational learning media like analog clock board was one of the solutions to improve students’ understanding.

This study aims to determine the effect of blended learning strategies on the creativity of the pre-service teachers. By a quantitative approach, the type used in this study is a quasi-experimental with pretest-posttest control group design. The population in this study were pre-service teachers in semester VII of the Mathematics Education Study Program at Universitas Negeri Medan. The instrument has used a test in the form of essay tests of 5 items concerning creativity.

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. The sample in this study was 62 students. The data collection method used was documentation and questionnaires. The instrument in this study used was test that was valid and reliable (r1 = 0.841 and r2 = 0.859).

This study aims to identify, analyze and map the results of students’ research on mathematics education in 2015-2018. This research used the CHAID algorithm that consists of 3 steps ie merging, splitting and stopping steps. The results of this research were (1) In 2015-2018, 51,9% of the students’ research used the classroom action research and 48,1% else used the descriptive, the analysis and the experiment. (2) 14,1% of the students used media for teaching and learning and 3,7% of them did not. (3) 8,1% were individual research and 5,9% were a collaboration or team research.

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.

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.

This study aims to identify students’ errors in solving problem equals to PISA’s based on Newman procedures. Qualitative-descriptive research was used in conducting this study and the subjects were third-grade students at SMP Unggul Sigli in year 2017/2018. Data was collected using tests and interviews. The instrument of this study was a sheet consisting of 5 (five) mathematical questions that composed equivalent to PISA’s problem.
