Abstrak: Tujuan penelitian ini adalah untuk mengetahui perbedaan hasil belajar siswa pada materi operasi hitung bilangan bulat dengan menggunakan model pembelajaran kooperatif tipe NHT dan model pembelajaran langsung di kelas VII SMP Negeri 14 Palu. Hipotesis yang diajukan dalam penelitian ini yaitu perbedaan hasil belajar siswa pada materi operasi hitung bilangan bulat dengan menggunakan model pembelajaran kooperatif tipe NHT dan model pembelajaran langsung di kelas VII SMP Negeri 14 Palu. Penelitian ini merupakan penelitian kuantitatif eksperimen dengan rancangan penelitian menggunakan One-Shot Case Study Design. Populasi penelitian ini adalah seluruh siswa kelas VII SMP Negeri 14 Palu yang terdaftar pada tahun ajaran 2016/2017 dan terdiri dari 10 kelas yang berjumlah 270 siswa. Teknik pengambilan sampel dilakukan dengan simple random sampling. Kelas yang menjadi sampel penelitian adalah siswa kelas VII Kenanga sebagai kelas eksperimen yang berjumlah 27 orang dan siswa kelas VII Matahari sebagai kelas kontrol yang berjumlah 27 orang. Hasil analisis data diperoleh nilai rata-rata kelas eksperimen 72,63 dengan standar deviasi 15,27 dan kelas kontrol 63,58 dengan standar deviasi 13,89. Berdasarkan perhitungan uji hipotesis diperoleh thitung = 2,30 dan ttabel = 2,000 pada taraf signifikan 0,05, karena nilai thitung > ttabel, maka H1 diterima dan H0 ditolak. Sehingga dapat disimpulkan bahwa terdapat perbedaan hasil belajar yang signifikan antara siswa yang mengikuti pembelajaran dengan model pembelajaran kooperatif tipe NHT dengan siswa yang mengikuti pembelajaran dengan model pembelajaran langsung. Kata Kunci: Model pembelajaran kooperatif tipe NHT, model pembelajaran langsung, hasil belajar. Abstract: The objective of this research is to know the difference of students achievement on addition and substraction of integer with using cooperative learning of NHT and direct learning in grade VII SMP Negeri 14 Palu. The hypothesis of this research is the difference of students achievement on addition and substraction of integer with using cooperative learning of NHT and direct learning in grade VII SMP Negeri 14 Palu. This research is experimental quantitative research with the research design using One-Shot Case Study Design. The research population is all students of grade VII SMP Negeri 14 Palu in the academic year 2016/2017 with 270 students. The sampling technique is done by simple random sampling. Classes which in the research samples are grade VII Kenanga as the experimental grade which consist of 27 students and grade VII Matahari as the control grade which consist of 27 students. From the achievement of data analysis, it obtained an average value of experimental grade is 72,63 with the deviation standard is 15,27 and the average value of control grade is 63,58 with the deviation standard is 13,89. Based on the hypothesis test calculations obtained tcount = 2,30 and ttable = 2,000 at the significant level of 0.05, because the value tcount > ttable , then H1 is accepted and H0 is rejected. So that it can be concluded that there is significant diference of achievement among students who follow the cooperative learning of NHT with the students who follow the direct learning. Keywords: Cooperative learning of NHT, direct learning, achievement.

This study aims to describe students’ mathematical communication skills in solving problems related to angle relationships, taking into account gender differences among students of SMP Negeri 1 Sindue Tobata. This research employed a qualitative approach with two eighth-grade students as subjects, consisting of one male and one female student, both identified as high-ability learners. Data were collected through tests and interviews. The results revealed that the male student demonstrated mathematical communication skills in understanding mathematical ideas both orally and in writing, using mathematical terms and notations, interpreting mathematical ideas through graphs and symbols, and evaluating ideas orally, although his written evaluations were still lacking. In contrast, the female student exhibited better skills in evaluating mathematical ideas both orally and in writing. These findings provide insights into the differences in mathematical communication skills between high-ability male and female students within the context of mathematics learning.
