This research was motivated by the lack of learning tools that can improve students' Mathematical Communication Skills (KKM). Activities that can encourage students to improve KKM have not been designed by the teacher in the learning device properly. This study aims to produce learning tools by applying Problem Based Learning models to improve KKM. This development research used the ADDIE development model with the stages of Analysis, Design, Development, Implementation, and Evaluation. The results of Syllabus, RPP, LKPD and KKM validation results showed highly valid criteria with percentages of 91.67%, 91.30%, 89.09%, and 87.15%, respectively. Practicality results indicate a very practical criterion with the percentage of small group trials at 95.57%, large group trials at 96.07%, and teacher responses at 96.25%. The effectiveness test results state that KKM of students who use learning tools with PBL models is better than KKM of students who use conventional learning.

The purpose of this research is to develop learning tools based for Algebra on Problem Based Learning (PBL) to support the mathematics communication ability of Junior High School students. Learning tools developed in this development research is students’ worksheets. The research method used is 4D model, which consists of 4 stages, namely define, design, develop, and disseminate. The results of worksheets’ validation by experts were 4,05 for the layout design and 4,19 for the content (both were categorized as valid). In addition, the students respons that the students’ worksheets were practical (with average of 3,94) and the teacher responses that these were very practical (with average of 4,23). Thus, based on the expert validation as well as the students and teacher of mathematics responses, the learning tools developed have already met the criteria of valid and practical and ready for the field testing to see its effectiveness on students’ mathematics communication ability.

This study aims to determine: (1) The differences in students' mathematical communication abilities by implementing Batak culture-oriented learning on problem-based learning (PBM-B3) and guided discovery (PT-B3) and (2) the interaction between learning models and students' gender towards students’ mathematical communication abilities. This research is quasi-experimental. The population of this study was first-grade students of SMP Swasta Putri Cahaya 2018/2019 with a sample taken from class VII-1 treated with the PBM-B3 learning model and class VII-2 treated with PT-B3 learning model. Each class consists of 14 male students and 14 female students. The research instrument used was a test of students' mathematical communication abilities. Data analysis was performed using covariance analysis (ANACOVA). Based on the research conducted, the results showed that: (1) There were differences in the students' mathematical communication abilities who were treated with the PBM-B3 and PT-B3 learning model after controlling the initial abilities of students. The interaction patterns of Dalihan Na Tolu found in the two learning models showed a positive effect on students' mathematical communication abilities because this interaction pattern is inherent in students which resulted in higher self-confidence in communicating ideas during problem-solving. (2) There was an interaction between the learning model and the gender of students on their mathematical communication abilities after controlling the initial abilities of students.

The purpose of this study was to assess the effect of Problem-Based Learning (PBL) approach on students' mathematical communication ability. The method used was quasi-experimental research with Posttest-Only Design. The subjects were 36 seventh grade students in one of Junior High Schools in Ternate. Students were grouped as control class (conventional learning) and experimental class (Problem Based-Learning / PBL). Research instruments were initial mathematical ability and mathematical communication test. The data was analyzed using Two Way ANOVA. Results showed that students' understanding of triangle concept was still not deep. Statistical analysis of the collected data showed that PBL effect on students' mathematical  communication  ability  was  insignificant  (p  =  0.370). Result  also  indicated  that  initial mathematical ability also has an insignificant effect on mathematical communication ability (p = 0.732). Keywords: geometry, mathematics communication ability, Problem Based-Learning.ABSTRAK Tujuan penelitian ini adalah mengkaji pengaruh pendekatan Problem Based-Learning (PBL) terhadap kemampuan komunikasi matematis siswa.

Siswa dikelompokkan berdasarkan kelas kontrol (pembelajaran konvensional) dan kelas eksperimen (pembelajaran berbasis masalah/PBL). Instrumen penelitian yang digunakan adalah tes kemampuan awal matematis dan komunikasi matematis. Teknik analisis data yang digunakan adalah uji Two Way Anova. Hasil penelitian menunjukkan bahwa pema- haman siswa tentang konsep segitiga masih belum mendalam. Analisis data secara statistik menunjukkan bahwa pembelajaran PBL tidak berpengaruh terhadap kemampuan komunikasi matematis siswa (p =0,370) dan kemampuan komunikasi matematis siswa juga tidak dipengaruhi oleh kemampuan awal matematis (p = 0,732). Kata kunci: Problem Based-Learning, kemampuan komunikasi matematis, geometri
