This study aims to determine whether the improvement of students' mathematical problem solving skills that get the learning of Model-Eliciting Activities is better than students who get regular learning. Method in this research is experiment and research design pretest and postest in experiment and control class. The population in this study were all students of MTs Kota Cimahi. School samples were taken at random, and obtained by MTs Negeri Kota Cimahi. Then the sample is selected two class VIII at random class. The experimental class uses Model-Eliciting Activities, while the control class uses ordinary learning. The hypothesis in this research is the improvement of student solving abilities of MTs students in Cimahi whose learning using Model-Eliciting Activities is better than using ordinary learning. Research data obtained through the instrument of posttest mathematical problem solving ability. The posttest data is processed by normality test, homogeneity test, and two average difference test using SPSS (Statistical Product and Service Solution) software version 16.0 for Windows. The results showed that the improvement of problem solving ability of MTs students in Cimahi whose learning using Model-Eliciting Activities was better than those using ordinary learning.

This study aims to develop a mathematics handout based on local wisdom nuanced to increase the mathematical problem-solving skill of the Secondary students. This research is motivated by the student’s ability to solve the social arithmetic problem. This study used four phases of developmental research such as Investigation, Design, Realization, and Test, Evaluation, and Revision. The characteristics of local wisdom were acquired within the design or context in the mathematics handout to develop secondary students problem-solving skills. The results show that the students do the stages of problem-solving by Polya, get the maximum score and show students’ positive responses in the questionnaire given. Therefore, it met the proper handout criteria such as valid, practice, and effective. In the future studies, we encouraged to develop learning materials which have a guide to do phases of problem-solving and apply the way to solve some problems in mathematics.

Communication Ability

This study aims to describe the ability of communication and problem solving of mathematical students in the material quadrilateral and triangle in class VII in one district of MTs Bandung. This type of research is qualitative research with phenomenology model which aims to interpret communication ability and ability to solve the mathematical problem of students. The subjects of this study were 24 students for communication skills and 25 students for math problem-solving skills. The result of data analysis shows that the mathematical communication ability of grade VII students in one MTs in Kabupaten Bandung is still relatively low with the highest percentage being in the low communication ability qualification which is 37.5%, while for students who have ability is get percentage equal to 29,2% and for students with high communication skills get a percentage of 33.3%, while for problem-solving skills in class VII is quite good with the highest percentage in qualification students with high problem-solving ability with a percentage of 44%, while for qualified students who ability is getting percentage by 40%, and for low qualifications only got a percentage of 16%.. Keywords: mathematical communication ability, mathematical problem-solving ability

This study is a quasi-experimental research using factorial design. This study aimed at finding the facts that had been resulted from the different influence caused by the use of Open-Ended method and that of STAD method on the students’ mathematical problem-solving skills in terms of learning achievement. The learning achievement was categorized into two types namely the high achievement and the low achievement. The population in this study was Grade V students from SD Negeri Serayu. The data were analyzed by ANAVA univariate test. The results of the study were as follows. First, there have been differences in the mathematical problem-solving skills of the students who had been taught using Open-Ended method and those who had been taught using the STAD method. Second, there were also differences on the students’ score. For the students who had been taught using the Open-Ended method, the highest posttest average score of their learning achievement was 95.71 while the lowest post-test average score of their learning achievement was 63.92. These students’ total average score of learning achievement was 81.04. On the other hand, for the students who had been taught using STAD the highest posttest average score of their learning achievement was 95.50 while the lowest posttest average score of their learning achievement was 70.00. These students’ total average score of learning achievement was 89.13. Third, there has not been any differences between the Open-Ended method and the STAD method.

Local Instruction Theory

This research aimed to develop local instruction theory that is valid, practical, and effective to help elementary school students developing their mathematical problem-solving skills. Therefore a sequential activityis design on dailybasis to encourage students to develop their ability to solve mathematical problems, especially on the topic division. To achieve the goal, realistic mathematics approach was implemented to grade three elementary students in the learning process. The designed activities were validated by experts on the aspects of mathematical contents, language, didactical process based on realistic mathematical approach. Data were analyzed with descriptive statistics and parametric statistics. The validation results show that the local instruction theory was valid, and the implementation shows that the local instruction theory is practical and effective in improving students' mathematical problem-solving skills.

AbstrakRendahnya kemampuan pemecahan masalah matematika siswa menyebabkan siswa kurang mampu menyelesaikan soal yang bersifat non rutin dan siswa masih kurang mengembangkan ide dan kemampuan yang dimilikinya. Penelitian ini bertujuan untuk mengetahui kemampuan pemecahan masalah matematika siswa melalui model Problem Based Learning berdasarkan Kemampuan Awal Matematika (KAM) siswa. Metode penelitian yang digunakan adalah kualitatif. Hasil penelitian ini menunjukkan bahwa kemampuan pemecahan masalah matematika siswa melalui model Problem Based Learning menjadi lebih baik. Sampel dalam penelitian ini adalah siswa kelas VIII-7 SMP Negeri 12 Padang yang terdiri dari 32 orang. Siswa yang awalnya berkemampuan rendah meningkat menjadi siswa berkemampuan sedang dengan peningkatan sebesar 75 %. Siswa yang awalnya tergolong berkemampuan sedang meningkat menjadi siswa berkemampuan tinggi sebesar 26 %. Siswa sudah mampu 1) memahami masalah, 2) menyusun rencana penyelesaian, 3) melaksanakan penyelesaian, dan 4) mengecek kembali jawaban. Analysis of Students' Problem Solving Abilities Based on Early Mathematical Ability AbstractThe lack of students' mathematical problem-solving skills causes students to be less able to solve problems that are non-routine and students are still lacking in developing their ideas and abilities. This study aims to determine students 'mathematical problem-solving abilities through the Problem Based Learning model based on students' Early Mathematical Ability (KAM). The research method used is qualitative. The results of this study indicate that students' mathematical problem-solving abilities through the Problem Based Learning model are better. The sample in this study were students of class VIII-7 Middle School 12 Padang consisting of 32 people. Students who were initially low-skilled increased to moderate-capable students with an increase of 75%. Students who were initially classified as capable were increasing to high-ability students by 26%. Students can 1) understand the problem, 2) draw up a settlement plan, 3) carry out the solution, and 4) re-check the answers.
