<![CDATA[This study aims to determine the validity of the development and practicality of using animated video teaching materials based on character education for class VIII SMP/MTs on linear equation systems. This research is a research and development research and development (R & D) using a 4D model consisting of 4 stages, namely, Define, Design, Develop, Disseminate. Product trials were carried out in small groups of 14 students of class VIII and mathematics teachers. The results of the study where at the validation stage consisted of 4 validation people, namely 1 media expert, 1 character education value expert and 2 material experts with an average validation percentage of 82.94% with the "Very Valid" category. At the product trial stage to determine the practicality of using this mathematics module using a small group test (student responses) and the teacher's response obtaining an average score of 81.62% in the "Good" category. So it can be concluded that the development of animated video teaching materials based on character education for class VIII SMP/MTs on the linear equation system material that has been developed is valid and practical so that it is feasible to be used in the learning process.

<![CDATA[This study aims to explain how elementary school students carry out their thinking processes to be able to solve problems in fractional material in fifth grade students of SDN Harjokuncaran 03 Sumbermanjing wetan Malang who have studied fractions. Data is obtained through the Think-Out-Loud (TOL) method or often called Think Aloud. In the TOL method, students are expected to be able to think critically and express in solving the problems obtained. The results of the study, students' thinking processes in solving problems, were taken by giving two fractional problems to each subject, namely 2 high-ability subjects (S1.1 and S1.2), 2 moderately capable subjects (S2.1 and S.2). ) and 2 subjects with low ability (S3.1 and S.3.1). After collecting data and analyzing it, the researcher can conclude that this study describes how the thinking process of elementary school students in solving problems that refers to Polya, including: (1) students can understand the problems obtained then identify sentences in the form of statements and question sentences then they are expected to be able to perform variable assumptions; (2) able to plan and be able to make appropriate solutions relying on the assumptions of variables, symbols, equations, and mathematical models; (3) elementary school students are able to participate in planning and problem solving by means of elementary students solving equations using algebraic properties and substitution; and (4) elementary students are able to review again by matching the results obtained with what is already known.

<![CDATA[This study aims to determine the effect of learning mathematics using teaching materials based on open-ended problems on students' positive attitudes. The research method used is the experimental method. Sample selection was done by random sampling technique. The population in this study were students of class VIII SMP Muhammadiyah Terpadu Bengkulu City. The selected sample was class VIII-A, which consisted of 28 people as the experimental class and class VIII-D, which consisted of 28 people as the control class. The results of this study indicate that the result is F = 16.06 where the value of sig <0.05 means that there is a significant interaction between students' attitude questionnaire scores (before-after) between classes (experimental-control). The interaction showed that the scores of students' attitude questionnaires between classes were significantly different. So it can be concluded that there is an effect of learning mathematics using teaching materials based on open-ended problems on students' positive attitudes. The effect of learning mathematics using teaching materials based on open-ended problems on the positive attitude of students in the experimental class is 89.8% while in the control class it is 53.8%. Keywords: positive attitude, learning mathematics, teaching materials, open-ended problems]]>

<![CDATA[This research aims to; (1) knowing the implementation of class actions using Connected Mathematics Project (CMP) learning; (2) knowing student activities in Connected Mathematics Project (CMP) learning; (3) find out whether Connected Mathematics Project (CMP) learning can improve mathematical critical thinking skills of second semester students of Mechanical Engineering at the Raflesia Polytechnic. This type of research is Classroom Action Research with four stages including: Action planning → action implementation → observation → reflection. The subjects of this study were students of the second semester of the Polytechnic, totaling 30 people. Data collection using observation sheets and test sheets. The results showed that the implementation of classroom action with the Connected Mathematics Project (CMP) learning was carried out well, marked by an increase in student learning activities which was offset by a decrease in activities carried out by the teacher so that effective student learning was obtained. Students' mathematical critical thinking ability increases can be seen from the results of the tests given, if in the pre-test results only 5 students reached the good category, then the post-test results as many as 26 students have reached the good category, with 3 indicators, namely identifying problems , generalize and analyze the algorithm has reached a good category, for indicators of solving problems in the category enough. In conclusion, learning using the Connected Mathematics Project (CMP) method for second semester students of Mechanical Engineering at the Raflesia Polytechnic is effective in improving student mathematics learning outcomes.

<![CDATA[This study aims to describe how student mathematics teacher candidates use context in learning mathematics. A qualitative approach is used as a research method with supporting instruments, namely questionnaires and interview guidelines. The subjects of this research are mathematics education students who program PMRI courses. Data collection techniques are documentation of student reports, giving questionnaires and interviews about the context of mathematics. Data were analyzed by coding to develop descriptions and themes to answer research questions. The results showed that students understood the context as limited to problems related to everyday life. Students have not been able to implement PMRI because there are students who focus on solving mathematical problems by students. In conclusion, students have not utilized the potential of the context so that students can learn to reconstruct mathematical concepts and hone mathematical thinking processes through problem solving.
