The purpose of this study was to examine the steps of the Index Card Match learning model with the problem posing approach assisted by MATLAB software and its effect on the problem solving ability of high school students. This research is a quasi-experimental research with non-equivalent control class design. The population in this study were all students of class XI Senior High School 2 Kuningan, with purposive sampling technique taken two classes as a sample. A distinctive feature of this combined model is that students make their own questions and answers on separate cards, so that after the cards are collected and randomized, students are asked to find suitable questions and answers. While the results of the data analysis showed the average initial problem solving ability of students in the experimental class is equal to the average initial ability of students in the control class with a significance value of 0.212. But after the treatment, there were differences in the average problem solving ability in the experimental class and control class that is equal to 3.38 and p-value of -2.563 with asymp. sig 0.010, rejection for H0 which means the mathematical problem solving ability in the experimental class is better than control class.

This community service activity aims to train lecturers of Universitas PGRI Palembang in writing scientific article, making presentation, and mathematics equations using LaTeX application, as well as understanding their responses toward the activity. This activity conducted employing assisting model with sharing tools, materials, and demonstration method, whereas 23 participants from different faculties joint the training. The response shows very positive satisfaction for all indicators with the range of 86% - 94%. The highest response is on the importance of the program, while time efficiency item scored 86%. All participants wish for sustainable training with longer time period.

Penelitian ini merupakan penelitian tindakan kelas (PTK) dengan subyek penelitian mahasiswa semester I pendidikan matematika STKIP Muhammadiyah Kuningan. Penelitian ini bertujuan untuk meningkatkan aktivitas dan hasil belajar mahasiswa pada mata kuliah Pengantar Dasar Matematika tahun akademik 2017/2018. Penelitian dilaksanakan melalui 2 siklus. Pada pre test rata-rata hasil belajar yang dicapai adalah 43, pada siklus I rata-rata hasil belajar menjadi 68,4 meningkat 25,4 atau sebesar 59%, sedangkan pada siklus II rata-rata hasil belajar menjadi 90 meningkat 21,6 dari siklus I atau sebesar 31,58%. Rata-rata aktivitas klasikal pada siklus I adalah72,36 sedangkan pada siklus II meningkat 12,74 menjadi 85,1, terjadi peningkatan 17,61%. Rata-rata hasil belajar portofolio pada siklus I adalah 77,80 sedangkan pada siklus II meningkat 8,43 menjadi 86,24, terjadi peningkatan 10,84%. Hasil penelitian menunjukkan pembelajaran dengan penilaian berbasis portofolio dapat meningkatkan aktivitas dan hasil belajar mahasiswa.

Students' mathematical literacy abilities are important to master, especially to formulate mathematical concepts that can be used in everyday life. Mathematical literacy has become an important issue lately to be developed in the study of mathematics learning. However, mathematical literacy has not become the main goal in the implementation of the learning carried out. The purpose of this study was to examine the comparison of students 'mathematical literacy skills with Adobe Flash Professional CS6-based RME learning with conventional learning and to examine the comparison of improvement in students' mathematical literacy skills with Adobe Flash Professional CS6-based RME learning with conventional learning. The research method used in this study was quasi-experimental with the design of a non-equivalent control group design. The results of the two research hypotheses were accepted. It is possible that the increase in students' mathematical literacy skills is triggered by the Adobe Flash Professional CS6-based RME learning which in the implementation of learning always focuses on self regulated learning.
