Kegiatan tatap muka yang sebelumnya dilakukan dialihkan menjadi proses pembelajaran daring. Peran orang tua dan pendidik sangat penting dalam proses pembelajaran daring. Pendidik dituntut untuk memahami teknologi dan memberikan sebuah metode pembelajaran yang dapat menggambarkan sebuah materi sesuai dengan perspektif yang diajarkan. Orang tua sangat berperan penting dalam mendampingi siswa dalam proses belajar mengajar. Proses pembelajaran daring dilakukan oleh pendidik dengan memberikan materi berupa file PDF (Portable DocumentFormat) yang disertakan dengan soal latihan. Proses pembelajaran seperti ini dinilai kurang efektif dan perlu adanya sebuah media pembelajaran secara visual, yang dapat meningkatkan pemahaman siswa akan materi yang disampaikan. Metode pembelajaran Multimedia Interaktif secara grafis dan visual mampu membantu siswa untuk memahami makna dari materi yang disampaikan pada saat proses pembelajaran. Media pembelajaran energi alternatif dengan menggunakan multimedia interaktif dapat diimplementasikan dengan metode penelitian research and development. Pengembangan media ajar interaktif mempermudah siswa dan guru dalam proses belajar mengajar. Evaluasi media ajar energi alternatif dengan pengukuran skala  Guttman dalam pengukuran construc sikap, menghasilkan  nilai sebesar 84 persen siswa sekolah dasar memahami materi energi alternatif.

The rapid development of technology today has prompted many applications to emerge that can be used as a learning media, one of which is Macromedia Flash. The reality in the field shows that the average score of basic chemistry final semester FT Unes classically is still low, namely 65 with the percentage of students who pass 42.85% and those who do not pass 57.15%. As a solution to this problem, research was carried out using Macromedia Flash as a learning media. The purpose of this study was to describe the perceptions of engineering students towards the use of animation media in basic chemistry lectures. This type of research is descriptive quantitative with the research sample being students at level I of the Faculty of Engineering and Planning, Ekasakti University in the basic chemistry lectures in the odd semester of 2020/2021 totaling 80 people who were selected by simple random sampling technique. The data collection technique used was a non-test technique in the form of a questionnaire. Based on the research results, it was found that engineering students who agreed that flash animation media could accelerate understanding of basic chemistry by 56.25% while 43.75% disagreed, engineering students who agreed that flash animation media could lead to solving problems based on basic chemical concepts were 60 % while 40% disagreed, engineering students who agreed that flash animation media was interesting to use in basic chemistry lectures were 75% while 25% disagreed, engineering students who agreed that flash animation media could facilitate understanding of abstract concepts in basic chemistry lectures were as much as 68.75% while 31.25% disagree, and engineering students who agree that flash animation media can increase motivation for basic chemistry lectures by 62.50% while 37.50% disagree.

In online learning, a strategy is needed in the delivery of learning material so that it can be optimally accepted by students. Flipped classrooms are an alternative learning model that can support the optimization of material delivery during the online learning process. The purpose of this study is to implement the flipped classroom learning model in online learning that is collaborated with the bloom taxonomy, to achieve learning objectives. The research method used is an implementation of the flipped classroom model and distributing questionnaires to collect data on the results of the implementation. The results obtained were positive responses from students in the implementation of online learning using the flipped classroom learning model, students were given instructions and directions in implementing the flipped classroom model from preparation outside the classroom to inside the classroom. The new habit that students apply during the implementation of the flipped classroom is to prepare discussion materials, so that during the live session, the atmosphere in online learning becomes more dynamic with questions and responses from students, the application of the flipped classroom model collaborates with the level of the bloom taxonomy domain (C1-C6) so that a structured learning process is formed so that it supports the learning objectives that have been set in the semester learning plan. The results of the questionnaire distribution also showed that more than 50% stated that they were good and agreed, if the flipped classroom learning model was implemented in the learning process.","PeriodicalId":329417,"journal":{"name":"Jurnal Teknologi Pembelajaran Indonesia","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124423044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
