The Relationship of Motivation and Self-regulated Learning through Blended Learning in the Covid-19 Era
Full text linkThis study aims to determine the relationship between motivation and self-regulated learning through blended learning in the covid-19 era. This study is a quantitative study with correlation study type. Samples were taken using random sampling techniques from all 1st-semester students who took basic physics courses and obtained 67 students consisting of 3 classes. The data was collected using the instrument of motivation and self-regulated learning in the form of a questionnaire which was filled in by the students after participating in basic physics courses using blended learning. The data that has been collected is then analyzed for normality and linearity. The data shows the results are normally distributed and linear so that data analysis can be continued with hypothesis testing using the Pearson product-moment correlation test and the value of R = 0.897 is obtained which is then compared with the R table at a significant level of 0.05, namely 0.244. Because R (0.897)> R table (0.244), it can be concluded that there is a positive relationship between motivation and self-regulated learning with the correlation coefficient value is 0.897 which is classified as very strong. Therefore, students' motivation and self-regulated learning through blended learning in the covid-19 era have a very strong relationship. This could be of concern to teachers and lecturers as facilitators in learning in this Covid-19 era. It is hoped that interesting learning using a blended learning approach can be applied so that student learning motivation increases and has a direct effect on students' desire to manage their own learning
Pre-Service Physics Teacher Conceptions and Visual Literacy to Observe Sky Maps throught Heaven View Media
Full text linkLearning science, especially learning astronomy subjects, is still very limited in activities carried out by students. The observation of the sky map provided is adequate as a learning media that can support student curiosity and concept understanding of stars for students. The research aims to explore the relationship between students 'conceptions of the stars using a sky map application, students' perceptions of Heaven Above media and visual literacy in the implementation of learning astronomy courses. Research participants involved 72 students who took astronomy lessons. The instrument consisted of a observation sheet and a questionnaire that had gone through the construct and content validation process. Data analysis using quantitative analysis factor analysis and determines normalized gain to descripe an increase in student visual literacy of stargazing. In addition, the calculation of the proportion questionnaire for students 'conceptions of learning and students' perceptions of the heaven view application then analyzes the factors to show the correlation. The result of this research is understanding that a deeper understanding of the concept and experience of maps is a need of students who can support the learning community in learning to observe more interesting stars. Visual literacy has increased between twice observation
The Effectiveness of Videos and Animations in Learning Physics in Junior High School Heat Materials
Full text linkAt the junior high school level, it is expected that learning Physics will provide students with knowledge and skills so that they can develop competency and hone science skills. Heat material is one of the junior high school physics materials which is dominated by concepts and principles so that it is considered difficult by students. The use of effective media can be one of the solution, namely the use of videos and animations in learning Physics. The type of this research is Research and Development which aims to develop videos and animations in learning physics of heat material. The effectiveness in using of videos and animations was carried out in a limited field test, namely in class VII3 SMP N 1 Pariaman even semester 2019/2020 using before and after experiments. The data collection instrument for the effectiveness test was in the form of tests of students' cognitive learning outcomes before and after using videos and animations. Furthermore, the data were analyzed using a correlated t-test. Based on the results of the analysis, the value of tcount = 6.91 and ttable = 2.04 (tcount > ttable). This shows that there is a significant difference between learning outcomes before using videos and animations in learning Physics and learning outcomes after using videos and animations in learning Physics. Thus, it can be said that videos and animations in physics learning are effective heat materials used in physics learning in class VII SMP Negeri 1 Pariaman
