Abstract

This study aims to determine the effectiveness of differentiated learning processes on the social mathematical skills of class VIII students at SMP Negeri 18 Medan. This type of research is quantitative descriptive research with the research population being all class VIII students at SMP Negeri 18 Medan. With a simple random sampling technique, a sample of class VIII-10 was obtained with 32 students. The instruments used were questionnaires and observations that had been tested for prerequisites in advance. After the differentiated learning process treatment was carried out, the results of the calculation of the learning quality questionnaire sheet reached an effectiveness category of 56% (moderate), the results of the calculation of the social skills questionnaire sheet reached an effectiveness category of 66% (moderate), the results of the calculation of the observation sheet for the suitability of the learning level to teacher activities obtained an average of 3.476 (good), the results of the calculation of the observation sheet on student activities obtained an average of 3.039 (good), the results of the calculation of the time allocation observation sheet obtained an average of 4 (good). Based on the quality of learning, the suitability of the learning level and time allocation, differentiated learning is effective for the social mathematical skills of class VIII students at SMP Negeri 18 Medan.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan deep learning melalui model problem based learning terhadap kemampuan pemahaman konsep pada materi SPLDV kelas X SMK Swasta Parulian 3 Medan. Penelitian menggunakan metode Quasi Eksperimen dengan populasi seluruh siswa kelas X yang terdiri dari 3 kelas. Sampel ditentukan melalui cluster random sampling, menghasilkan kelas X-TSM sebagai kelas eksperimen dan kelas X-TKR-2 sebagai kelas kontrol. Data dikumpulkan menggunakan tes kemampuan pemahaman konsep. Analisis data dengan uji normalitas Liliefors, homogenitas F, dan Uji t-test menunjukkan perbedaan antara nilai pre test dan post-test kemampuan pemahaman konsep pada kedua kelas, dengan nilai sig. (P(T<=t) two-tail) sebesar 0,0069 < 0,05. Rata-rata nilai post-test kelas eksperimen mencapai 67,9667, sedangkan kelas kontrol 36,7000, menunjukkan kemampuan pemahaman konsep siswa berada pada kategori tinggi. Berdasarkan perhitungan koefisien determinasi, diperoleh nilai sebesar 87,5% yang artinya menggunakan pendekatan deep learning melalui model problem based learning memberikan pengaruh sangat besar terhadap kemampuan pemahaman konsep siswa.
