The Mathematical Connection Ability is part of the thinking ability that must be possessed by a person. Therefore this ability should be customized to be applied in everyday problem-solving apps. The purpose of the research is to determine the strength of mathematical connection in multiplications at the 3rd grade of Nurmadani Elementary School, Pekanbaru Indonesia. The subjects consisted of 28 students (10 male and 18 female). The research uses descriptive-qualitative approach and classroom action research. Data were collected using a form of activity data of teachers and student during the learning process and interview. This study consists of 2 cycles. The results showed that 80% of students could use multiplication in everyday life, and 92% of the students could represent that multiplication as a form of repeated addition.
ABSTRAKPenelitian ini bertujuan untuk memperoleh bukti empiris tentang keefektifan model pembelajaran kooperatif tipe STAD dan TPS ditinjau dari aspek prestasi dan minat siswa SMP terhadap matematika. Penelitian ini adalah penelitian kuasi eksperimen dengan desain completely randomized factorial design. Sampel penelitian adalah siswa kelas VII dari dua sekolah yang ada di Kabupaten Kebumen. Instrumen penelitian terdiri atas tes dan angket minat yang berisi soal-soal uraian dan item pernyataan untuk mengetahui keefektifan model pembelajaran ditinjau dari aspek prestasi dan minat belajar siswa. Hasil penelitian menunjukkan bahwa terdapat perbedaan prestasi yang signifikan untuk kelas STADA (p= 0,046), STADB (p= 0,000), TPSA (p= 0,000), dan TPSA (p= 0,042). Pada aspek minat, kelas STAD dan TPS juga berbeda signifikan (p=0,001, ). Hasil analisis Multivariat menunjukkan bahwa terdapat interaksi antara model pembelajaran dengan jenis sekolah (p=0,001). Dapat disimpulkan bahwa model pembelajaran kooperatif tipe STAD dan tipe TPS efektif ditinjau dari aspek prestasi maupun minat siswa terhadap matematika.Kata kunci: pembelajaran kooperatif, STAD, TPS, prestasi, dan minat belajar matematika.
ABSTRACTThis study aimed to get empirical evidence about the effectiveness of STAD and TPS cooperative learning on junior high school students' achievement and interest in mathematics. This study was a quasiexperimental research design with completely randomized factorial design. Sample were seventh grade students from two schools in Kebumen. The research instruments consisted of tests and interest questionnaire which contains questions and statement to determine the effectiveness of the learning model on students' achievement and interest. The results showed that there was significant difference in achievement for STADA class (p = 0.046), STADB (p = 0.000), TPSA (p = 0.000), and TPSA (p = 0.042). In terms of interest, STAD and TPS significantly differed (p = 0.001, p <0.005). Multivariate analysis results show that there was interaction between learning model with the type of school (p = 0.001, p <0.005). It can be concluded that STAD and TPS cooperative learning were effective from the aspect of students' achievement and interest in mathematics.
Penelitian ini bertujuan untuk menghasilkan media pembelajaran interaktif berbasis android pada materi transformasi menggunakan Articulate Storyline 2 yang valid. Metode penelitian ini adalah research and development menggunakan model ADDIE. Model ini selanjutnya dimodifikasi sesuai kebutuhan dari peneliti menjadi 1) Analysis, 2) Design, 3) Development, 4) Implementation, dan 5) evaluation. Pengumpulan data menggunakan angket kevalidan dan angket kepraktisan dari siswa. Teknik analisis data digunakan analisis secara deskriptif kuantitatif dan kualitatif. Subjek penelitian ini merupakan dua validator ahli dan praktisi, serta siswa SMP kelas IX sebanyak 15 orang. Hasil penilaian dari empat validator diperoleh rata-rata penilaian sebesar 87,19 dengan kategori sangat valid. Kemudian hasil analisis respon siswa terhadap media pembelajaran diperoleh rata-rata sebesar 94,72 yang termasuk kategori praktis. Berdasarkan hasil analisis data dari validasi ahli dan praktisi serta angket respon siswa dapat disimpulkan bahwa media pembelajaran interaktif berbasis android menggunakan Articulate Storyline 2 pada materi transformasi yang dikembangkan sangat valid dan sangat praktis.
