Analysis of Problem Solving Ability in Quadrilateral Topic on Model Eliciting Activities Learning Containing Ethnomathematics

Abstract: The low ability to solve mathematics problems and the character of local cultural love is due to lack of habituation in problem-solving that is associated with everyday life situation and the learning model used is not in accordance with local cultural values. This study aims to analyze the validity, the practicality, the effectiveness of the learning tools implementation, and the characteristics of the problem-solving ability of learners on the learning of MEA with ethnomathematics. The research method used was mixed method of concurrent embedded model. At the beginning of the study was given an initial problem-solving test in experiment and control classes as well as giving a questionnaire of the love of local culture in the experimental class, then the experimental MEA learning was carried out on the experimental class and the PBL learning in the control class. At the end of the study, final tests on the problem-solving ability was conducted in experimental and control classes as well as giving a local love questionnaire in the experimental class. The results showed that the MEA learning containing ethnomathematics on quadrilateral topics is valid, practical, and effective. The results of the characteristics of the problem-solving abilities analysis of the upper group, students have been able to solve the problem properly according to Polya's steps, the problem-solving ability of students in the middle group is still difficult in the step of calculating, while the students in the lower group have difficulty in planning a solution.

Analysis of Mathematical Problem Solving Skills using Meta-Cognitive Strategy from The Perspective of Gender-Based Self-Efficacy

Abstract: This research aims to analyze the effect improved self-efficacy in students’ ability to solve mathematical problems from the gender perspective with the implementation of meta-cognitive strategy for the topic of prism and pyramid. It is a mixed method research using the concurrent embedded model. Subjects involved were students of Class VIII (eighth grade) of MTs Asy-Syarifah Mranggen (Islamic Junior High School of Mranggen). It is found in the field that when students have to deal with applied mathematics concerning everyday life problems of significant difficulty level, they are not confident about their own abilities to solve them. Results show that 1) Self-efficacy greatly influences students’ ability in solving mathematical problems; 2) At the same level of self-efficacy, boys and girls undergo the same process and get the same results in terms of mathematical problem solving skills; 3) Students have different levels of ability in solving mathematical problems based on self-efficacy; 4) There has been an increase in self-efficacy prior to and after the implementation of met-cognitive strategy for the topic of prism and pyramid.

Discovery Learning - PMRI in Improving Mathematics Literacy of Junior High School Students

Abstract: The lack of mathematical literacy is a worrying thing. It must be noticed that the literacy is an important ability that must be owned by students as future stakeholders. The objective of this study is to analyze the discovery learning - PMRI which effectively improve students' mathematical literacy. The type of research used was quantitative research, experimental research with quasi-experimental design nonrandomized control group, pretest – posttest design. The determination of control and experiment class was by using random sampling technique. The experimental class was treated in the form of discovery learning - PMRI while the control class is given discovery learning - scientific learning. The data were collected using mathematical literacy test, observation, and interview. The data from the data analysis of the final score of mathematical literacy, it is found that (1) the proportion of students in discovery learning-PMRI that fulfills the Minimum Criteria of Mastery Learning is 70, it reaches 70%; (2) the average of students’ mathematical literacy on discovery learning - PMRI is better than the average of students' mathematical literacy on discovery learning, and (3) The improvement of mathematics literacy of discovery learning class - PMRI is higher than discovery learning - scientific class . So it can be concluded that discovery learning – PMRI is effective in improving students' mathematical literacy.

Analysis of Mathematical Connection Ability in Geometry at MEA Learning Based on Spatial Intelligence

Abstract: Problem solving activities require students to apply mathematics rules on non-routine problems. Mathematical connection ability is required so that students can relate real problems to mathematical model nor relate the interrelationships between the concepts that required to solve problems. This study aims to examine the effectiveness of MEA in geometry and to analyze the mathematical connections ability of students in geometry based on upper, middle, and lower spatial intelligence categories on MEA. The research method is Mixed Methods and research design is Sequential Explanatory Design. The subjects of the study is the 9th grade students. The study started by first spatial intelligence test in experimental class, then followed by MEA learning in experimental class and expository learning in control class. The study ended by mathematical connection ability test in experimental and control classes and last spatial intelligence test in experimental class. The results showed that MEA learning in geometry were effective. The result of mathematical connection ability in geometry of upper spatial intelligence category students has reached five indicators of mathematical connection ability well. Students of middle spatial intelligence category on first, second and fourth indicators have been maximized, but third and fifth indicators have not been maximized. Students of lower spatial intelligence category on first indicator have been maximized, second indicator has not been maximized, while third, fourth and fifth indicators can not be achieved well. Teachers should know the spatial intelligence of students so that the learning process especially in geometry achieve maximum results.
