Practicum based learning is required to provide opportunities for students in finding and applying concepts by observation. Student worksheet with discovery learning model and equipped with AR video are needed as learning tool, so students will be able to have good work in laboratory and implementation of practicum is effective. This study aims to produce LKPD and AR media that is videos related to the topic of practicum. The method used in this study is a research and development method with the Dick and Carey model approach. The feasibility test was carried out on the product using a Likert scale instrument. Feasibility test on material experts obtained a score of 96.93%, on media experts at 89.95%, on learning experts at 81% and obtained an average score of 89.29% with a very proper interpretation. Next, a user trial was conducted on the product with respondents, which are at SMAN 54 Jakarta. Trials on teachers obtained a score of 97.61%, and trials on students obtained a score of 88.47%. The limited trials is done by doing pre-test and post-test on students. Limited trial results obtained an average n-gain score of 0.47. Based on the results of the feasibility test, user trials, and limited trials, it can be concluded that the developed student worksheet is very suitable to be used as a learning tool in physics practicum activities in senior high school at 10th grade.
The development of information and communication technology (ICT) in the 21st century makes it easier for students to be more active in the learning process. Physics learning materials are needed to support the problem-based learning process in high school. This study aims to produce e-learning models for problem-based learning on Heat and Thermodynamics topics. The result shows media can be used in learning in high school class XI. We uses the research and development method, with the Dick and Carey model. The study was conducted in a digital media laboratory, Physics Education Department of Universitas Negeri Jakarta from January to June 2018. E-Learning models have been produced for problem-based learning in the topic of Heat and Thermodynamics. This WordPress-based E-Learning model can display physics material enriched with images, graphics, animations, simulations, and videos. Students are facilitated to understand the concepts learned. The e-learning model is equipped with assessment tools that can be used online. Students are facilitated to learn independently without limited space and time. The E-learning model developed was also equipped with discussion groups in the form of chats for all registered users. The media validation obtained the results of system evaluation, content, and e-learning infrastructure with 78.9 points average. The material validation gives an 81.55 rating. Concerning media and material, e-learning media is declared feasible as a medium for self-learning. The e-learning model for problem-based learning is feasible to use to train the ability to critical thinking, creative thinking, collaborative, and communicate for students in high school.
This article aims to publish research results on the development of physics textbooks equipped with 3D media based on Augmented Reality technology. AR Technology can provide solutions when students face difficulties illustrating physics material in physics learning textbooks. This research uses the research & development method of the Dick & Carey model. The resulting book displays physics material in multi representations with verbal forms, pictures, tables, graphs, mathematical equations, and 3D media. Augmented Reality technology-based multi representation is displayed with a marker that is scanned through a smartphone application with an Android system. The scanning process requires an average of two seconds from each marker. The time of this scan shows that the media produced is more effective and efficient when compared with the activities of searching and downloading animations or videos by students. The feasibility of the book was tested with a Likert scale questionnaire instrument. For material, the worthiness was 71.45% while 93.3% for the media. The trial results are limited to five materials giving N-Gain values ranging from 0.3 to 0.47. Based on these results it can be concluded that the book model enriched with 3D media with AR technology is already feasible as a textbook in learning physics.
Penelitian pengembangan bertujuan untuk menghasilkan perangkat e-learning pada matakuliah Fisika Dasar II. Perangkat yang digunakan dalam pengembangan e-learning adalah learning management system (LMS) Chamilo. Metode yang digunakan adalah metode penelitian pengembangan dengan pendekatan yang dikembangkan oleh Walter Dick and Lou Carey. Perangkat e-learning yang dikembangkan sudah sampai pada tahap evaluasi formatif. Hasil pada validasi ahli media, ahli pembelajaran dan ahli materi menyatakan bahwa perangkat e-learning secara keseluruhan sudah layak sebagai perangkat pembelajaran Fisika Dasar II. Hasil uji coba terbatas pada mahasiswa juga menghasilkan bahwa perangkat yang dikembangkan sudah berfungsi serta menarik untuk digunakan sebagai bahan belajar mandiri.
