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.

Abstract

This study aims to: (1) find out the quality of reciprocal teaching with recitation and self assessment on the achievement of mathematical representation abilities, (2) describe the ability of mathematical representation in terms of student learning independence, and (3) determine the effect of learning independence on students' mathematical representation abilities in reciprocal teaching with recitation and self assessment. This research is a mixed method type of concurrent embedded design type. The subject of this study was determined based on the learning independence score using a learning independence questionnaire in the eighth grade students of MTs Urwatil Wutsqo Jepara. Data collection techniques are using tests, questionnaires, and interviews. The quality of learning is analyzed based on three quality categories, namely planning, implementation and assessment. The effect of learning independence on mathematical representation ability was analyzed based on simple linear regression test. The results showed that (1) the three domain qualities of learning were categorized as good, so it was concluded that the quality of reciprocal teaching with recitation and self-assessment of mathematical representation abilities was good. (2) students with high learning independence are able to master all mathematical representation indicators well compared to students with moderate and low learning independence; (3) learning independence has a positive effect on the ability of mathematical representation on reciprocal teaching with recitation and self assessment.
