Development of Problem Based Learning Tools to Improve Mathematical Communication Skills and Self Efficacy of Students

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.

Mathematical communication skills are one of the competencies that students must have in the 21st century. This study aims to anylize and describe students’ mathematical communication skills in terms of self efficacy on the polyhedrons material. The research used descriptive qualitative methods. The subjects were 9 grade students of An nashichah private junior high school selected purposively. Data was collected through online test, questionnaires and interviews using WhatsApp. The data analyzed through 3 stages, namely data reduction, data presentation and conclusions. The results showed that the students’ mathematical communication skills were low. When viewed from students’ self efficacy, high self efficacy students have high mathematical communication. Meanwhile, low and moderate self efficacy students have low mathematical communication skills. The use of Whatsapp media is not able to support students mathematical communication skill and self efficacy. The tachers need to design learning media to help students improve their mathematical communication skills and self efiicacy.

Penelitian ini menggunakan pendekatan penelitian kuantitatif dengan metode eksperimen semu. Sampel yang digunakan pada penelitian masing-massing yaitu 30 siswa (kelas eksperimen) dan 30 siswa (kelas kontrol) sekolah dasar di beberapa sekolah sekitar kota Rantauprapat. Hasil penelitian ini menunjukkan bahwa (1) peningkatan kemampuan komunikasi matematis siswa yang diberi pendekatan realistik lebih tinggi daripada siswa yang diberi pembelajaran konvensional, (2) adanya interaksi antara pendekatan pembelajaran dengan kemampuan awal siswa terhadap peningkatan kemampuan komunikasi matematis dan self-efficacy matematis, dan (3) proses penyelesaian komunikasi matematis siswa yang menggunakan pendekatan pembelajaran matematika realistik lebih baik dari pendekatan konvensional. Berdasarkan hasil penelitian dapat disimpulkan bahwa PMR lebih baik dari pendekatan matematika konvensional dalam meningkatkan kemampuan komunikasi dan self-efficacy matematis siswa.Improvement of Students’ Mathematical Communication Skills and Self-Efficacy through the Realistic Mathematics Learning ApproachAbstractThis study aims to determine the improvement of students' mathematical communication skills and self-efficacy through a realistic mathematics learning approach (PMR). This research uses a quantitative research approach with quasi-experimental methods. The samples used in each research were 30 students (experimental class) and 30 students (control class) in elementary schools in several schools around the city of Rantauprapat. The results of this study indicate that (1) an increase in mathematical communication skills of students who are given a realistic approach is higher than students who are given conventional learning, (2) there is an interaction between learning approaches with students' initial ability to improve mathematical communication skills and mathematical self-efficacy, and (3) the process of solving students' mathematical communication using a realistic mathematics learning approach is better than the conventional approach. Based on the results of the study it can be concluded that PMR is better than conventional mathematical approaches in improving students' mathematical communication skills and self-efficacy.

Mathematical communication skills of students are still relatively low. One learning model can improve students 'mathematical communication skills and at the same time students' mathematical disposition is the Problem Based Learning (PBL) model. The aim to be achieved is to find out the improvement of students 'mathematical communication skills and mathematical disposition using PBL models in terms of students' initial mathematical level. This research is an experimental research design with pretest posttest control group design. The research population was Grade VII students of SMP 9 Langsa. Students are grouped into two classes namely the experimental class and the control class randomly selected from eight parallel classes. The instrument used was a test of mathematical communication skills and a mathematical disposition questionnaire. Data analysis was performed using two-way ANOVA. The results showed that improving students 'mathematical communication ability and students' mathematical disposition by applying PBL learning models is better than students applying conventional learning models. There is no interaction between the PBL learning model with student level on mathematical communication skills and students' mathematical disposition. Abstrak Kemampuan komunikasi matematis siswa masih tergolong rendah. Salah satu model pembelajaran dapat meningkatkan kemampuan komunikasi matematis siswa dan sekaligus disposisi matematis siswa adalah model Problem Based Learning (PBL). Tujuan yang ingin dicapai ialah untuk mengetahui peningkatan kemampuan komunikasi matematis siswa dan disposisi matematis menggunakan model PBL ditinjau dari kemampuan awal matematis siswa. Penelitian ini merupakan penelitian eksperimen dengan desain pretest postest control group design. Populasi penelitian adalah siswa kelas VII SMP Negeri 9 Langsa. Siswa dikelompokkan menjadi dua kelas yaitu kelas eksperimen dan kelas kontrol yang dipilih secara acak dari delapan kelas paralel. Instrumen yang digunakan tes kemampuan komunikasi matematis dan angket disposisi matematis. Analisis data dilakukan dengan menggunakan anova dua arah. Hasil penelitian menunjukkan bahwa peningkatan kemampuan komunikasi matematis siswa dan disposisi matematis siswa dengan menerapkan model pembelajaran PBL lebih baik dari pada siswa yang menerapkan model pembelajaran konvensional. Tidak terdapat interaksi antara model pembelajaran PBL dengan level siswa terhadap kemampuan komunikasi matematis dan disposisi matematis siswa.

Mathematical communication skills are important, and education should facilitate students to improve their mathematical communication skills. The purpose of this study was to develop e-learning based on Moodle to improve students' mathematical communication and self-efficacy and student self-efficacy and describe how to students’ mathematic communication and student self-efficacy. This study used mixed-method research. The population in this study were Year 5 students at a private primary school. Data collection techniques used in this study are observation and tests. The implementation with Moodle was effective to the students’ mathematic communication and self-efficacy student. Overall, the students’ mathematical communication skills and self-efficacy of students using E-learning based Moodle is better than those using conventional learning. Also, self-efficacy positively affects students' communication skills with a very strong correlation coefficient, meaning that the higher students' self-efficacy, the higher students' communication skills.
