Developing CORE model-based worksheet with recitation task to facilitate students’ mathematical communication skills in linear algebra course

This research is a quasi-experimental study that aims to determine the comparison of students' mathematical communication abilities with the cooperative learning model of the NHT and PPT media in class VII SMP Negeri 02 Ngabang. The population in this study were all students of class VII SMP 02 Ngabang consisting of 3 classes. The sample in this study was taken by using the Random Sampling Cluster technique. Class VII A as class I experimental class with 24 students and class VII B as a experimental class II with 24 students. The instruments used were pretest and posttest in the form of description. Data analysis uses the t test with a significance level of 5%. The results showed the average posttest for the NHT class was 72.5 and the average posttest for the PP class was 66.666. From the posttest hypothesis test results obtained t hitung> t tabel (1.9522> 1,667). Because t_hitung> t_tabel, H_0 is rejected and H_a is accepted. This means that students' mathematical communication skills taught with the NHT are better than using Power point media.

ABSTRACTThis research is motivated by the fact that the ability of mathematical communication in Indonesia is low. The models and approaches used in the learning process are one of the supporting factors for learning mathematics in the classroom. This study aimed to analyze SMA 1 Namlea students' mathematical communication skills with realistic mathematics learning assisted by GeoGebra. The research method used is quasi-experimental. WHO researched SMA Negeri 1 Namlea, Buru Regency. The analysis results show that the test instrument is valid and reliable to be used for pretest and posttest. The results showed that the mathematical communication of students who received realistic mathematics learning assisted by GeoGebra was better than students who received realistic mathematics learning without GeoGebra. The results also showed that there was a positive response from students towards learning realistic mathematics with GeoGebra.KEYWORDS: Realistic Mathematics, GeoGebra & Mathematical Communication

Mathematical communication skills of junior secondary school students in coastal area are still considered low due to the lack of contextual problem technique in the teaching of mathematics. The various potencies of the coastal area have been damaged without any concern. It is interesting to investigate the contextual problem in mathematics teaching because it can be identified, required, and related to everyday life. The objective of this study is to enhance mathematical communication skills of junior secondary school students in the coastal area. Using coastal-based contextual teaching and learning (CCTL) can enhance: (1) students’ mathematical communication skills better than conventional teaching and learning (CVTL); and (2) the students’ learning activity, fluency of argument in problem solving process, advanced question skills, and knowledge of coastal area potencies and problems.

Persentase siswa yang tuntas pada tes kemampuan komunikasi matematika mencapai 84,38% dan pada tes prestasi belajar mencapai 81,25%.Kata Kunci: perangkat pembelajaran, pembelajaran berbasis masalah, kemampuan komunikasi matematika, prestasi belajar Developing a Problem-Based Learning Instructional Kit Oriented to Junior High School of Mathematical Communication Skills and Learning Achievement AbstractThe research aims to produce a good quality problem-based learning mathematics instructional kit oriented to mathematical communication skills and learning achievement consisting of lesson plans, student worksheets, communication skill test, and learning achievement test. This study was a research and development. The procedure of this model consisted of three steps are define, design and develop. The result shows that the mathematics instructional kit is valid with a “good” category. Learning kit that has been developed was practically shown by results of practicality votes by teachers in category “good”, “very good” category based on student’s responses and “very good” category based on the observation of learning implementation. Learning kit that has been developed was effective based on student’s learning mastery. The percentage of students who achieved the mastery level in communication test is 84.38% and in learning achievement test is 81.25%.Keywords: instructional kits, problem-based learning, mathematical communication skills, learning achievement

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.
