ABSTRAKPenelitian ini bertujuan untuk menguji pengaruh model pembelajaran berbasis masalah (PBM) terhadap kemampuan pemecahan masalah fisika dan peningkatan sikap ilmiah siswa. Penelitian dilakukan dengan menggunakan dua jenis disain penelitian yang berbeda, yaitu Pre-Experimental Design dengan bentuk One Group Pretest-Posttest Design untuk melihat pengaruh model PBM terhadap kemampuan pemecahan masalah dan Quasi Experimental Design dengan bentuk Nonequivalent Control Group Design untuk melihat pengaruh model PBM terhadap peningkatan sikap ilmiah. Sampel diambil menggunakan teknik purposive sampling dengan kelas X MIPA C sebagai kelas eksperimen dan kelas X MIPA D sebagai kelas kontrol. Teknik pengumpulan data menggunakan tes uraian untuk kemampuan pemecahan masalah dan angket untuk mengukur sikap ilmiah. Analisis pengaruh model PBM terhadap kemampuan pemecahan masalah dilakukan dengan perhitungan gain yaitu pengurangan rata-rata posttest dengan pretest, diperoleh hasil pengurangan sebesar 27,09, sedangkan analisis pengaruh model PBM terhadap peningkatan sikap ilmiah siswa dilakukan dengan uji-t dua sampel independen, dilihat dari skor rata-rata N-gain sikap ilmiah siswa kelas eksperimen dan kelas kontrol diperoleh t hitung lebih besar dari t tabel yaitu 3,47 > 2,00 pada taraf signifikan (α=0,05). Maka dari hasil penelitian dapat disimpulkan terdapat pengaruh model PBM terhadap kemampuan pemecahan masalah fisika dan sikap ilmiah siswa di SMAN 2 Kota Bengkulu. Kata kunci : Model Pembelajaran Berbasis Masalah, Kemampuan Pemecahan Masalah Fisika, dan SikapIlmiah. ABSTRACTThe aims of this study were to examine the effect of problem based learning (PBL) model to physics problem solving ability and improvement of students' scientific attitudes. This study was conducted by using two different types of research designs, namely Pre-Experimental Design with the form of One Group Pretest-Posttest Design to see the effect of PBL model to problem solving ability and Quasi Experimental Design with the form of Nonequivalent Control Group Design to see effect of PBL model on improving the students' scientific attitudes. Sampels were taken using purposive sampling technique with class X MIPA C as experiment class and class X MIPA D as control class. Data collection technique used to essay test physics problem solving ability and questionnaire to measure the students' scientific attitudes. Analysis of the effect of PBL model on the ability of physics problem solving done with the gain calculation is the average posttest reduction with pretest, then get the reduction result by 27,09, while analysis of the effect of PBL model was to improvement of students' scientific attitudes done with two independent samples t-test, seen by average score N-gain students' scientific attitudes in experiment class and control class get result t greater than t table is 3,47 > 2,00 at significant level (α=0,05). Therefore, that was the result of this study concluded there is the effect of PBL model to physics problem solving ability and students' scie...
This study aimed to develop e-module physics based Kvisoft Flipbook Maker (KFM) on the materials of harmonic motion in spring vibration material as a supporting learning material for the tenth-grade students of Senior High School. The study adapted the 4D development models (Define, Design, Develop, and Disseminate) in which the define stage was to describe problems in learning, the design stage was to produce initial products and research instruments, the develop stage was to obtain product and instrument feasibility, and the disseminate stage was for the widespread deployment of KFM-based Physics e-modules. The study subjects numbered 34 students in the tenth grade of Mathematics and Science (MIPA) 1 of Senior High State School (SMAN) of 1 PAKEM, samples were taken using purposive sampling. The research instruments employed were preliminary study questionnaires, material expert validation survey form, media expert validation survey form, and critical thinking skills tests. The data collection methods applied in this paper were validation, observation, pre-test, post-tests, and study of documentation. Data analyzing used was sign test. The results of the paper showed that 1) KFM-based Physics emodules developed fall into the valid category and are worth using. 2) Students' critical thinking skills during learning activities had improved significantly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
