Using E-Comics Based on Realistic Mathematics Education in Transformation Geometry
Get PDFThe very rapid development of technology in the era of Society 5.0, requires lecturers to package learning that is interesting for students, one of which is with media and learning approaches from abstract material to concrete material. The purpose of this research is to produce e-comic products with a realistic approach. mathematics education in geometry transformation courses that can be used in online tutorials for 4th semester mathematics education study program students at Universitas Terbuka. This research method uses the Dick & Carey development design by including eight steps. Based on the results of student questionnaire responses using e-comic media with a realistic mathematics education approach, namely based on the results of student assessment responses, an average value of 86% was obtained, which means that e-comic media is classified as good as a learning medium. Meanwhile, based on the test of the effectiveness of the use of media on students, it is obtained tcount 3.285 > ttable 2.002 from the two results from the t-test through comparison it can be concluded that H0 is rejected and Ha is accepted, which means that it means that there is a difference in the average learning outcomes between tutor class scores and the class media score. This means that the e-comic media learning outcomes with the RME approach to this transformation geometry material is effectively used for students of mathematics education program at the Universitas Terbuka. Keywords: research & development, e-comics, realistic mathematics education. DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1769-177
The Effect of The Problem Based Learning on Students Science Process Skills in Learning Physics: A Meta Analysis
Get PDFRevolution 4.0 requires humans to have 21st century skills. The 21st century guides human resources that are able to compete with the wider community, so the government seeks to improve human resources through education. Thinking skills that are expected to achieve optimal learning outcomes are science process skills, because with these thinking skills students will be able to build meaning and confirm their understanding of a physical concept symptom and emphasize the importance of direct experience involvement in the learning process. The learning model that emphasizes learning as a process that involves solving problems in an actual context is the Problem based Learning model. Based on the description above, it can be stated that there are several researchers who have conducted research on the effect of problem based learning models on students' science process skills. So a meta-analysis of 15 articles was carried out, there was a significant effect of the problem based learning model on students' science process skills in learning physics based on grade level, physics subject matter and student learning outcomes. Keywords: problem based learning, science process skills, physics. DOI: http://dx.doi.org/10.23960/jpmipa/v23i2.pp651-66
