Abstract

This study aims to find out the  effect of using online learning platform on academic  performance  of plant morphology course. The subjects in this study students majoring in Biology at Universitas Negeri Medan. This research is a study using is descriptive with a quantitative approach. The results showed that Students are declared capable of using online learning platforms indicated by the average results of internet searching 88% hypertext navigation 87%, content Evaluation 85% and Knowledge Assembly 81%. (2) Biology student understanding on the final test score is said to be in the very high category with an average of 89.9% and the mid-term grades are categorized as moderate with an average of 85.17%. (3) There is a correlation between student learning literacy and maser the concept through the online learning platform with a correlation of recount = 0.71297.  So students have been able to take advantage of use the online learning platform well in plant morphology course

Abstract

This study aims to determine the feasibility of using STEM-based interactive multimedia on human digestive system for elementary school. This research is a Research and Development which refers to the ADDIE model which consists of 5 stages, namely the analysis, design, development, implementation, and evaluation stages. Data collection techniques in this study were observation, interviews, and validation. This research was conducted in class V. The results showed the multimedia was valid in terms of media by 91,20%, in terms of material by 94.44%, and interms of instructional design by 93,33%. This multimedia is “Very Feasible” for participants touse in learning education. Furthermore, the results of the assessment from the teacher obtained 93% and limited trials by students obtained 94% which is in the very good category.Keywords: Interactive Multimedia, STEM, Elementary School.

Abstract

This research aims to describe: Validity and practicality of scientific-based LKPD using the Discovery Learning model. This research is development research using the ADDIE model which was carried out in class VI of SDN 173662. The research results obtained are: The module developed has been categorized as Valid, Practical and Effective. Based on the validation results of the material expert, the category was "Very Good" with an average percentage of 81.7%, the validation results of the language expert stated that the LKPD developed was in the "Very Good" category with an average percentage of 95%. Furthermore, the learning expert revealed that the LKPD developed was in the "Very Good" category with an average percentage of 86.7%, so it was concluded that the LKPD developed was very valid. Furthermore, based on teacher responses of 90% and student responses of 96%, the LKPD developed was practical to use. So it can be concluded that the student worksheet developed is valid and practical to use in class VI.

Abstract

Penelitian ini bertujuan untuk menginvestigasi efek Problem-Based Learning (PBL) dengan pendekatan STEM terhadap kemampuan pemecahan masalah dan sikap ilmiah siswa kelas VII pada materi ekologi. Penelitian ini menggunakan desain quasi-eksperimental dengan rancangan pretest-posttest kelompok. Teknik pengambilan sampel menggunakan simple random sampling. Instrumen penelitian dalam penelitian ini adalah tes esai kemampuan pemecahan masalah dan kuesioner sikap ilmiah siswa. Data dianalisis menggunakan uji prasyarat dan uji-t (independent sample t-test). Berdasarkan hasil analisis data, terdapat efek signifikan (sig(2-tailed)) < 0,05 dimana 0,000 < 0,05 pada kemampuan pemecahan masalah dan sikap ilmiah siswa di kelas eksperimental. Berdasarkan uji hipotesis, ditemukan bahwa terdapat efek model PBL dengan pendekatan STEM terhadap kemampuan pemecahan masalah dan sikap ilmiah pada materi ekologi untuk siswa kelas VII di SMP Muhammadiyah 01 Medan.

Abstract

This study aims to determine the effect and correlation of applying the discovery learning model on students’ science process skills and learning outcomes regarding food and the digestive system at Imelda Private Junior High School in Medan. This study uses a quantitative approach Pretest-Posttest group design. The instrument used in this study was a learning outcome test consisting of 20 multiple-choice questions with a reliability value of 0.851. The data analysis techniques used were normality test using Shapiro Wilk, homogeneity test, hypothesis test using the right-tailed t-test, and N-Gain test. The results of the observation of science process skills obtained all indicators of science process skills have a very high category. The average learning outcome of the experimental class is 76.04. Higher than the control class which is 70.83. The results of the right-sided t-test with a significance level of α = 0.05, obtained tcount> ttable, namely 1.84> 1.65. The N-Gain value on learning outcomes is 62.45. The results of the study indicate that the application of the Discovery Learning model has a significant effect on science process skills and student learning outcomes on food and digestive system materials.
