Abstract. This study aims to determine whether there are differences in mathematical problem solving abilities of students who are taught through an investigative approach and with conventional approaches in class VIII SMP 9 of Pematangsiantar. This type of research is experimental research. The population in this study were all eighth grade students of SMP 9 of Pematangsiantar as many as 8 classes. The problem solving abilities of students taught with an investigative approach to the average pretest of 57.73 and post-test of 85.42, the level of change in problem solving abilities was 27.69. Higher than the problem solving abilities of students who are taught with conventional learning the average pretest is 56.67 and posttest is 72.67. Hypothesis testing, from the calculation of student pretest data obtained at dk = 64 and the real level α = 0.05 and 𝑡(1−12∝)=𝑡0,975 obtained ttable = 1.669 and tcount = 1.172. Because tcount < ttable = (1.172 <1.669) it can be concluded that the initial ability of students is the same. While based on the calculation of student posttest data obtained at dk = 64 and the real level α = 0.05 obtained ttable = 1.669 and t count = 4.212. Because tcount> ttable (4.212 > 1.669) then Ho is rejected and Ha is accepted. Then it was concluded that there were significant differences between problem solving abilities taught by an investigative approach and conventional approaches.Keywords: Problem Solving Ability, Investigative Approach, Conventional Approach.

The study began with observations at VIII Rengat Barat Middle School students of class VIII. This study aims to determine students' mathematical problem solving abilities using the Learnig Starts With A Question model. This type of research is experimental research (experimental research) with a quasi-experimental design research design. The research design used was The Randomized posttest-only control design. The sampling technique uses Simple Random Sampling. In this study the instrument used was a test of students' mathematical problem solving abilities. Data obtained on the problem-solving ability test were analyzed using the Independent Samples T-Test based on the results of the hypothesis test, the value of tcount = 2.014 and ttable = -1.999 with (df) n-2 and significance <0.05 (0.048 <0.05). As for the Independent Samples T-Test testing criteria, reject H0 if t> t table. Based on that, H0 is rejected because tcount = 2,014> ttable = -1,999. So it can be concluded that the students 'mathematical problem solving ability using the Learning Starts With A Question learning model is better than the students' mathematical problem solving ability using the conventional model in class VIII of SMP Negeri 4 Rengat Barat.

This study was employed to enhance learning motivation and mathematical problem-solving abilities of class VIII A students of SMP Negeri 7 Purwokerto through SFAE learning with problem-solving strategies. The subjects of this study were 31 students of class VIII A SMP Negeri 7 Purwokerto. This study is a Classroom Action Research (CAR), which was conducted collaboratively and participative. The action research was carried out in 3 cycles, with each cycle consisting of 2 meetings. Students were given a questionnaire to measure learning motivation and a test to measure their mathematical problem-solving abilities at the end of each cycle. Data collection techniques in this study include observation, questionnaires, tests, and documentation. Data analysis was carried out by descriptive qualitative and quantitative. The finding showed that implementing of SFAE learning with problem-solving strategies could increase students’ learning motivation and mathematical problem-solving abilities. The study found that (1) The average percentage of the overall learning motivation questionnaire is steadily increased from 61.71% in cycle one to 68.10% in cycle two and 76.03% in cycle three. (2) The average percentage of student tests for problem-solving abilities in cycle one also significantly increases from 35.21% to 53.20% in cycle two and 79.61% in cycle three. The average student test rate for each indicator of problem-solving ability has met the study’s success criteria.

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.

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.
