The data in this study were obtained from the results of filling out questionnaires and also interviews. Sources of data in this study were the subjects from which the data were obtained, namely students of class XI-MIPA 3 SMA N 1 Tawangsari. The data analysis technique used was data reduction, data presentation and conclusion drawing. The results of the data analysis from the questionnaire showed that the average percentage of student responses to mathematical reasoning abilities on the matrix material was 60.75% and was in the medium category. With the percentage on each indicator, namely on indicator 1 (students do calculations with the applicable mathematical formula / rules) of 55.63% so that it is included in the moderate category, students with the moderate category have aspects of the ability to understand question commands and are only weak at calculation operations. In indicator 2 (students draw general conclusions based on mathematical processes / concepts) the percentage is 61.25% so it is included in the medium category. In indicator 3 (students make estimates) the percentage is 81.25% so that it is included in the high category, students with high categories have aspects of the ability to understand question commands, question logic and can complete counting operations. While the percentage on indicator 4 (students draw conclusions based on the similarity of mathematical processes / concepts that are seen) is 54.5% so it is included in the low category, students with low categories have aspects of the question's melogical ability and are only weak in counting operations. The average percentage of the four indicators is 63.16% so that student responses can be said to be in the medium category. In this study, checking the validity of the data used triangulation techniques, namely by comparing the results of the study with the results of interviews. From the comparison of data analysis with questionnaires and interviews, it can be concluded that students with mathematical reasoning on the matrix material are in the medium category.

Thematic Learning

The research objective was to develop thematic teaching materials based on Problem Based Learning in the two sub-theme of the diversity of living things in grade IV elementary schools. The development of teaching materials is motivated by the need for learning that can improve students' ability in problem solving, the ability to think critically, and foster curiosity. This type of research is development research (research and development). The development model used is the 4-D model which consists of the stages of defining, designing, developing and disseminating. The define stage will carry out an analysis of the curriculum, student analysis and needs analysis. The design stage is carried out by designing the lesson plans and teaching materials. The development stage is carried out by testing the validity, practicality and effectiveness test. The disseminate stage cannot be carried out because of the covid pandemic 19. The results of the research at the design stage obtained RPP and teaching materials designed by following PBL steps. The development stage based on the validity test of teaching materials is categorized as valid. At the effectiveness stage, the results showed that the teaching materials were effective so that they were easy to use by fourth grade students of SDN 03 Muaro. Based on these results, it can be concluded that the thematic learning tools based on Problem Based Learning on the sub-theme of the Diversity of Living Things for grade IV SD that have been produced can be declared valid, practical and effective.
