<![CDATA[This quasi experimental research aimed to know the influence of problem-based learning model on student’s mathematical problem solving skill. The population of this research was all of grade eighth students of SMP Al-Azhar 3 Bandar Lampung in academic year of 2013/2014 as many as 247 students that was distributed into six classes. By purposive sampling technique, it was chosen VIII D and VIII E class as samples. Based on the hypothesis test, it was found that the increasing of student's mathematical problem solving skill with the problem-based learning was higher than conventional learning. Thus, it can be concluded that the problem-based learning model affects the student's mathematical problem solving skill.Penelitian eksperimen semu ini bertujuan untuk mengetahui pengaruh model pembelajaran berbasis masalah terhadap kemampuan pemecahan masalah matematis siswa. Populasi penelitian ini adalah seluruh siswa kelas VIII SMP Al-Azhar 3 Bandar Lampung tahun ajaran 2013/2014 sebanyak 247 siswa yang terdistribusi dalam enam kelas. Dengan teknik purposive sampling, terpilih kelas VIII D dan VIII E sebagai sampel. Berdasarkan pengujian hipotesis, diketahui bahwa peningkatan kemampuan pemecahan masalah matematis siswa dengan pembelajaran berbasis masalah lebih tinggi dari pembelajaran konvensional. Jadi, disimpulkan bahwa model pembelajaran berbasis masalah berpengaruh terhadap kemampuan pemecahan masalah matematis siswa.Kata kunci: konvensional, pembelajaran berbasis masalah, pemecahan masalah matematis]]>

<![CDATA[This qualitative research aimed to describe the student’s critical mathematics discourse in Socrates scientific learning. The subjects of this research were 9 students of VII-D class of MTs Negeri 2 Bandar Lampung in academic year 2018/2019 consists of each 3 students with high, medium, and low mathematical ability. The data of this research were obtained through observation, interview, and documentation. Data analysis were processed through three steps that refered to Miles and Huberman models, which were data reduction, data display, and conclusion drawing. Based on the research, the results were: (1) The number of students who did the critical mahematics discourse was successfully increased by Socrates scientific learning, (2) Student’s critical mathematics discourse through Socrates scientific learning more dominantly showed the indicator of student’s critical thinking skill in interprettation and analysis, (3) Student’s critical mathematics discourse was more likely to occur when the teacher asked Socrates’ questions types of clarifycations and reasons and evidence of investigation, (4) Student’s critical mathematics discourse more dominantly showed when the students did scientific approach, which were associating and communicating.]]>
