Kooperatif Tipe Numbered Heads Together Terhadap Kemampuan Pemecahan Masalah Matematis Siswa di MTs  Unwanul Falah  Kupang Rejo  Kecamatan Punduh Pidada Kabupaten Pesawaran. Jenis penelitian yang digunakan adalah eksperimen semu (quasi  eksperimen). Populasi dalam penelitian ini siswa kelas VIII di MTs  Unwanul Falah  Kupang Rejo  Kecamatan Punduh Pidada Kabupaten Pesawaran Tahun Ajaran 2019/2020 yaitu sebanyak 70 orang siswa. Pengambilan sampel memakai metode non probability sampling. Uji hipotesis yang digunakan adalah uji t. Hasil Penggunaan model pembelajaran  NHT ini memberikan sumbangan yang signifikan terhadap kemampuan pemecahan masalah matematis siswa pada mata pelajaran matematika. Hasil penelitian diperoleh kemampuan pemecahan masalah siswa setelah diberikan model pembelajaran NHT lebih tinggi dibandingkan dengan kelas control yang tidak di beri NHT. Ada Pengaruh Pembelajaran Number Head Together Terhadap Kemampuan Pemecahan Masalah Matematis Pada Siswa Kelas VIII di MTs  Unwanul Falah  Kupang Rejo  Kecamatan Punduh Pidada Kabupaten Pesawaran Tahun Ajaran 2019/2020.

The purpose of this study was to determine the effect of the numbered head together learning model on students’ mathematical problem solving abilities at MTs Unwanul Falah Kupang Rejo, Punduh Pidada District, Pesawaran Regency. This study used quasi-experimental. The population of this study were 70 students at class VIII in MTs Unwanul Falah Kupang Rejo, Punduh Pidada District, Pesawaran Regency in Academic Year 2019/2020. The sample was taken by using non-probability sampling method. The hypothesis test of this study used the t test. The result of the use of the NHT learning model had made a significant contribution to students’ mathematical problem solving abilities ub mathematics. The results obtained by students’ problem solving skills after being given an NHT learning model were higher than the control class wich was not given the NHT. This could be seen from students who are given the NHT. There was an effect of learning numbered head together on student’ mathematical problem solving abilities in at class VIII in MTs Unwanul Falah Kupang Rejo, Punduh Pidada District, Pesawaran Regency In Academic year 2019/2020.

This research aimed to find out the differences of the improvement of students mathematical creative thingking skill using open ended. This research used quasi experimental method whith pretest-posttest control group. The subjects of this research were 60 students at class VII in one of the MTs in Bandar Lampung city. There are two classess in this study namely the experimental class consisted of 30 students getting open ended learning models and the second control class consisted of student getting scientific approach. The instrument of this study used student creative thingking skill test, based on mathematical creative thingking indicator. The result of this study showed all of improvement of mathematical creative thingking students ability getting open ended learning model was not better then students getting scientific approach.

The purpose of this study is to determine whether there are differences in the average learning outcomes of mathematics and which are higher average learning outcomes of mathematics between students who use the learning methods Problem Based Learning and Problem Solving. This type of research is experimental. Data analysis techniques using the ttes formula. The results showed that: (1) there were differences in the average learning outcomes of mathematics between students who used the Problem Based Learning and Problem Solving learning methods at SMPN 2 Metro, this was known based on the calculation of the hypothesis test obtained thit = 2,60 and tdaf = 2,00 so thit> tdaf. (2) the average student learning outcomes using the Problem Based Learning method are higher than the Problem Solving learning method in mathematics learning for VIII grade students of SMP Negeri 2 Metro 2016/2017 Academic Year, this is known based on the two average test difference, obtained thit = 2,53 and tdaf. = 1,67 so thit > tda

Penelitian ini bertujuan untuk mengembangkan bahan ajar matematika denganmetode PQ4R untuk menanamkan kemampuan pemahaman konsep matematis siswa. PQ4R adalah metode pembelajaran yang dilakukan dengan kegiatan membaca. Kegiatan dalam proses pembelajarannya yaitu preview, question, read, reflect, recite dan review. Kemampuan pemahaman konsep matematis kemampuan siswa dalam menerjemahkan, menafsirkan, dan menyimpulkan suatu konsep matematika.Sabjek dalam penelitian ini adalah siswa kelas VIII B SMP Daarul Ma’arif tahun pelajaran 2016/2017 yang memiliki karakter berpikir menengah ke bawah. Data penelitian diperoleh melalui lembar observasi, dan wawancara. Hasil penelitian menunjuka bahwa pengembangan bahan ajara matematika dengan metode PQ4R efektif jika bahasa yang digunakan jelas, dibuat keterangan penjelas pada langkah-langkah penyelesaian pada contoh soal, latihan yang dibuat jangan terlalu banyak dan sebaiknya berbentuk soal cerita. Sebagian besar siswa menyukai bahan ajar matematika ini dan bahan ajar ini dapat menanamkan kemampuan pemahaman konsep matematis siswa.
