Abstract

This study aims to measure the level of validity, practicality and effectiveness of Problem Based Learning social arithmetic teaching materials assisted by Liveworksheets. This study uses the Research and Development (R&D) method of Sugiyono's development model which consists of 10 stages which are limited to step 7, namely: potential and problems, data collection, product design, design validation, design revision, product trial, and product revision. The research subjects were: a VII grade math teacher, 10 VIII grade students, and 30 VII grade students. Instruments in this study include: interview sheets, validation sheets, student response questionnaires, and mathematical communication skills tests. Data processing techniques in the form of quantitative data analysis include validity analysis, practicality analysis, and effectiveness analysis of test results. The results of this study that LKPD teaching materials have met the eligibility criteria. This is because based on the results of the validation of experts who get a score of 80% which is considered valid. In the limited product trial, a score of 81% was obtained in the very practical category. As well as extensive product trials obtained a score of 85% with a very practical category. Then during the effectiveness test, it got a score of 80% with the effective category. Thus teaching materials in the form of learner worksheet are suitable for use in the learning process.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh self confidence terhadap kemampuan koneksi matematis siswa SMP. Metode yang digunakan pada penelitian ini yaitu metode korelasional dengan pendekatan kuantitatif. Sampel yang diambil dalam penelitian ini yaitu sebanyak 30 siswa disalah satu SMP di Kota Cimahi, instrumen yang digunakan pada penelitian ini antara lain tes dan non tes. Tahap yang dijalani dalam penelitian ini siswa diberikan angket self confidence yang terdiri dari 42 pernyataan, pengisian soal tes kemampuan koneksi matematis, analisis data dan terakhir pengambilan kesimpulan. Hasil dari penelitian yang telah dilakukan diperoleh bahwa self confidence siswa memberikan pengaruh positif terhadap kemampuan koneksi matematis yaitu sebesar 36,9% dan 63,1% dipengaruhi oleh faktor lain di luar self confidence siswa.
