This study aims to produce instructional materials in the form of electronic module based learning content development system on the matter of pattern number. This research method is Research and Development (R & D) based on ADDIE model. Assessment of material experts on the learning media is included in the category of "Valid" with an average value of 3.46. The media expert's assessment of this e-module is included in the "Valid" category with an average grade of 3.66. The linguist's assessment of this medium is included in the "Valid" category with an average grade of 3.6. In a small-scale trial followed by 10 students of class VII obtained an average score of 3.65 based on the results of a response questionnaire that has been filled by the learner, this result puts the e-module on the criteria "Very Interesting". In large-scale field trials followed by 30 students, the average score of attractiveness obtained was 3.55 on the criteria "Very interesting".

Bahan ajar merupakan sarana atau alat pembelajaran berisi suatu materi, metode pembelajaran, batasan-batasan, serta cara mengevaluasi yang dirancang secara sistematis serta menarik untuk mencapai kompetensi pembelajaran. Namun kenyataannya pembelajaran matematika menggunakan bahan ajar buku cetak yang sulit dimengerti dalam segi bahasa maupun penjelasan dan pendidik belum membuat bahan ajar berbasis REACT. Penelitian ini bertujuan untuk menghasilkan bahan ajar berbasis REACT pada materi relasi dan fungsi dan untuk mengetahui efektifitas bahan ajar berbasis REACT pada materi relasi dan fungsi. Metode penelitian ini adalah Research and Development (RD) menggunakan model ADDIE yang terdiri dari Analysis (Analisis), Design (Perancangan), Development (Pengembangan), Implementation (Implementasi), Evaluation (Evaluasi). Berdasarkan data hasil validasi ahli materi diperoleh rata-rata skor 4,28 dengan kategori “sangat layak” dan ahli media dengan rata-rata skor 4,01 dengan kategori “sangat menarik”. Sedangkan respon peserta didik mengenai bahan ajar menghasilkan rata-rata skor pada skala kecil yaitu 4,4 dengan kriteria aspek kemenarikan “sangat menarik” dan skala besar yaitu 4,69 dengan kriteria aspek kemenarikan “sangat menarik”. Hasil penilaian uji efektifitas memperoleh skor N-Gain sebesar 0,688 dengan kualifikasi “sedang” dan untuk skor effect size sebesar 2,06 dengan kategori “tinggi” atau dapat dikatakan tingkat keefektifan “tinggi”. Jadi bahan ajar berupa modul pembelajaran matematika berbasis REACT pada materi relasi dan fungsi dinyatakan telah layak, menarik, dan efektif untuk digunakan sebagai bahan ajar dalam proses pembelajaran.

The purpose of this study is to find out whether there are: (1) the influence of the scientific approach on students’ critical thinking skills; (2) the influence of learning independence on students’ mathematical critical thinking ability; (3) the interaction between the scientific approach and the learning independence of students’ critical thinking skills. This research is a quasy experimental design research with 2x3 factorial design. Sampling technique in this research use probability sampling with cluster random sampling. The research instrument used is questionnaire self-reliance learning and test of critical thinking ability mathematically. Data from the results of tests of mathematical critical thinking ability were analyzed using anava test of two unequal cell paths and further tests using a double comparison test with the Scheffe method. The results showed that: (1) there was an influence of the scientific approach on students’ critical thinking skills; (2) there is influence of learning independence to students’ critical thinking ability mathematically; (3) there is no interaction between the scientific approach and the learning independence of mathematical critical thinking skills.
