The aims of this study are to determine level of problem solving ability after being given problem solving basedlearning and to determine the effect of problem solving based learning to problem solving ability in probability theory. Themethod used is quasi experimental, with pre-experimental design and one shot case study design. The population are the studentsof fifth semester in IKIP PGRI Pontianak and it consists of 3 classes. Sample just consists of a class, which obtained throughcluster random sampling technique. Instrument used is problem solving ability test. Data is analyzed using descriptive statisticsand inferential statistics. The study show that the problem solving based learning doesn’t give good effect to problem solvingability, but it has average score is 67 or good level. Beside of that, the study also show that students have ability of understandingthe problem with the average score is 75 or high level, ability of devising the plan with the average score is 66 or high level,ability of carrying out the plan with the average score is 50 or middle level, and the average score is 19 or very low level forability of looking back.

One way to improve students' self-confidence is to implement a collaborative learning model. Improving students' self-confidence using collaborative learning models can be done by conducting classroom action research. The subject of this class action research is the students of class X MIPA 4 SMA Negeri 2 Ngaglik, Sleman, Yogyakarta School Year 2015/2016 consisting of thirty two students. This study consists of two cycles. Technique Data collection used is test and non test. The instrument of this study is the test of student achievement and student confidence questionnaire. Data analysis techniques consisted of the conversion of qualitative data to quantitative and student mastery calculation. The average of student achievement before treatment is 40.3125 with the complete proportion of students is 3.125% and after treatment is 87.9167 with proportion of student which is complete is 100%. The average student self-confidence before treatment was 96.46875 with moderate category and after treatment was 109.2188 with high category. The results showed that collaborative learning model can improve student's self-confidence.

Penelitian ini bertujuan untuk mengetahui penerapan model pembelajaran Kooperatif Tipe Teams Games Tournament untuk meningkatkan kemampuan pemecahan masalah matematis siswa pada materi segitiga kelas VII. Jenis penelitian yang digunakan adalah kuantitatif dengan metode eksperimen. Desain penelitian yang digunakan True Experimental dengan menggunakan bentuk penelitian Pretest-Posttest Control Group. Populasi penelitian adalah semua siswa kelas VII MTs Ushuluddin Singkawang yang terdiri dari kelas VII A,VII B,VII C, VII D, VII E, VII F dengan jumlah 140 orang. Sampel penelitian diambil menggunakan probability sampling, dengan teknik simple random sampling maka didapat kelas VIIA sebagai kelas eksperimen dengan jumlah 22 orang dan kelas VIIB sebagai kelas kontrol dengan jumlah 22 orang. Hasil analisis data menunjukkan bahwa; 1) Terdapat peningkatan kelas eksperimen sebesar 0,51 dan hasil uji-t dua sampel diperoleh 3,54 > 2,08 sehingga terdapat perbedaan peningkatan kemampuan pemecahan masalah matematis siswa antara kelas yang diberikan model pembelajaran Teams Games Tournament dengan kelas yang diberikan pembelajaran konvensional pada materi segitiga; 2) Aktivitas siswa dengan menggunakan model pembelajaran Teams Games Tournament tergolong aktif yaitu memperoleh persentase sebesar 77%; 3) Respon siswa terhadap pembelajaran matematika tergolong positif terhadap penerapan model Teams Games Tournament pada materi segitiga dengan persentase sebesar 86%.

This research implements Problem Based Learning and Discovery Learning model to analysis the increase of mathematical creative thinking skills, mistakes in the process of mathematical creative thinking, and self-efficacy of high school students in Tasikmalaya. The research method used is descriptive, data collection techniques through creative thinking ability tests and questionnaires mathematics self-efficacy. The instruments were previously assessed by experts in mathematics education. Based on the data analysis, it is concluded that the mathematical creative thinking abilities of students through Problem Based Learning is increasing compared to the mathematical creative thinking abilities of students through Discovery Learning. Mistakes students of mathematical creative thinking processes in Problem Based Learning, generally on flexibility and originality indicators. While at Discovery Learning, mistakes students of mathematical creative thinking processes is generally on sensitivity, flexibility and originality indicators. Flexibility is solving the problem with a variety of different ways, but the result is the same, and originality is to solve the problem in its own way does not use a standard formula. Sensitivity is the ability to detect problems. Self-efficacy of students in Problem Based Learning and Discovery Learning are both at high qualifications.

This research is a comparative experiment. This study aims to determine the effect of the application of cooperative learning model Two Stay Two Stray (TSTS) towards mathematics learning outcomes through comparison with the results of studying mathematics taught using direct learning model. Population, namely the eighth grade students of SMP Negeri 2 Polong Bangkeng Utara Kabupaten Takalar semester of academic year 2016/2017, with a sample of students in grade VIIIA and VIIIB class. The data were analyzed using descriptive statistical analysis techniques and inferential statistics. Descriptive analysis showed that the average student learning outcomes experimental class at the high category, an average of 80.78 with a standard deviation of 11.28; and the average student learning outcomes control class in middle category with an average score of 73.82 with a standard deviation of 12.98. Inferential analysis results obtained H0 and H1 accepted. It can be concluded with 95% confidence that the results of students 'mathematics learning through cooperative learning model Two Stay Two Stray (TSTS) higher than the results of students' mathematics learning through direct learning model.
