This study aims to determine the differences in mathematical communication skills of students in the material opportunities by using PBL and CTL learning models in class X of the Al-Istiqomah Private Vocational School in the Regency of Java. This type of research is semi-experimental. The population in this study were all students of class X of Private Al-Istiqomah Vocational School, Regency of Java. The research sample was 2 classes. The results of the research obtained F_count> F table which is 15.31> 3.99, so to test the hypothesis it can be concluded that rejecting H0 means thank Ha, there are differences in mathematical communication skills of students taught using problem based learning models with students taught using Contextual Teaching learning models Lerning. There are differences in mathematical communication skills of students taught using a problem-based learning model compared to students who are taught using the 9% Contextual Teaching Lerning learning model
Tujuan penelitian ini untuk mengetahui apakah terdapat interaksi antara model pembelajaran dengan kemampuan awal matematik siswa terhadap kemampuan komunikasi matematik siswa. Jenis penelitian ini adalah semi eksperimen. Penelitian ini dilaksanakan di SMK Swasta Al-Istiqomah Kec. Tanah Jawa. Sampel penelitian ini terdiri dari 2 kelas eksperimen yaitu kelompok eksperimen 1 kelas X SMK TKJ dengan jumlah 34 orang dan kelompok Eksperimen 2 kelas X TKR dengan jumlah 34 orang. Hasil analisis data terhadap tes kemampuan awal, tes kemampuan komunikasi matematis siswa menunjukkan bahwa data berdistribusi normal dan memiliki varians yang homogen. Selanjutnya untuk menjawab rumusan masalah digunakan ANAVA dua jalur. Dari hasil perhitungan ANAVA didapat kesimpulan bahwa: Terdapat interaksi antara model pembelajaran dengan kemampuan awal matematika siswa terhadap kemampuan komunikasi matematis siswa. Kata kunci: Interaksi, kemampuan Awal, komunikasi matematis
This study aims to determine whether there is an effect of the use of Camtasia-based audio visual media onstudents' mathematics learning outcomes in class XI Mathematical Logic Material of Muhammadiyah 5Vocational School in Asahan Regency 2016/2017 Academic Year. This type of research is quasiexperimental, which is the sample of the study there are 2 classes (class XI AP-1 and XI AP-2) taken incluster random.Then given a different treatment, the experimental class with the conventional Visual Assisted MediaLearning learning model and the control class with conventional methods. After the learning was completed,posttest was obtained with the results of the experimental class averages 78.7 and the control class 74.7. Theresults of t-test obtained thitung = 2.10> t table = 1.67 then Ha is accepted, thus it can be concluded thatthere is influence of the use of Camtasia-based Audio Visual Media on Student Mathematics LearningOutcomes in Class XI Mathematical Logic Material of Muhammadiyah 5 Kisaran District Asahan2016/2017 Academic Year.Keywords: Use of Camtasia Application-Based Audio Visual Media, learning outcomes, MathematicalLogics
Penelitian ini bertujuan untuk mengetahui pengaruh pembelajaran dengan media komik terhadap kemampuan pemecahan masalah siswa di kelas VIII SMP Negeri 1 Kisaran. Penelitian ini merupakan penelitian quasi eksperimen dengan desain penelitian two group pretest dan posttest. Sampel dalam penelitian ini adalah kelas VIII-A dan VIII B masing-masing sebanyak 26 siswa. Setelah pembelajaran selesai diberikan, diperoleh posttest dengan hasil rata-rata kelas eksperimen 80,81 dan kelas kontrol 69,385. Hasil uji t diperoleh thitung = 6,442 > ttabel = 1,67 maka Ha diterima, dengan demikian dapat disimpulkan bahwa ada pengaruh pembelajaran dengan media komik terhadap kemampuan pemecahan masalah siswa di kelas VIII SMP Negeri 1 Kisaran.
AbstrakPenelitian ini merupakan penelitian deskriptif yang bertujuan untuk menganalisis bagaimana kesulitan belajar yang dimiliki oleh siswa SMA kelas X pada materi sistem persamaan linier tiga variabel.
