A domain of research in physics teaching is focused on the study of the effects of different types of learning interventions aimed to help students build a scientific conception. Microscopic Virtual Media (MVM) is the application of a particular interest in physics learning because they can support microscopic powerful modeling involving physics concepts and processes. In this study, one group (experimental) of 19-20 year old students were studied to determine the MVM role in the development of a functional understanding of the concept of expansion of solids. The experimental group used MVM using DLSM (Dual Situated Learning Model). The results presented here indicate that students work with virtual media exhibited significantly higher scores in research tasks. Our findings strongly support that MVM can be used as an alternative instructional tool, in order to help students reduce their scientific misconceptions and develop an understanding of physics concepts.

Penelitian ini bertujuan untuk mengetahui kelayakan media pembelajaran Virtual Physics Lab (ViPhyLab) dalam Praktikum Hukum Kirchhoff. Metode penelitian yang digunakan adalah metode Research and Development (R&D) menurut Sugiyono, dengan subjek penelitian ini adalah 3 validator untuk mengetahui kelayakan media ViPhylab dan 16 siswa kelas XI MIPA SMA Al-Fath Cilegon yang digunakan untuk mengetahui tanggapan siswa terhadapa media ViPhyLab. Hasil penelitian menyatakan kelayakan media ViPhyLab hasil pengembangan yaitu sebesar 87,45% dengan kategori sangat layak dan tanggapan siswa terhadap media ViPhyLab menyatakan sebanyak 90,4% siswa menanggapi media ViPhyLab dengan kategori sangat baik.

The aims of this research to design Massive Online Open Courses (MOOCs) from now on referred to as Virtual Microscopic Simulation (VMS) to measure the Level Understanding (LU) of the construction of microscopic phenomena electric-field conceptions. The research method used is a mixed-method using embedded design. The research subjects are high school students, and one of the universities in Banten Province. The results of this study are software with features in the form of MOOCs-VMS that are categorized very well based on expert judgment on aspects of usability and learning content. The average score of media expert validation score is 96% with a very feasible category, the average score for material expert validation is 98% with a very decent category, and the average user response rate is 86% with a very good category. It can be concluded that the design of MOOCs-VMS can be used as an alternative media for conducting distance learning and is significant in building the level of understanding students.

Electricity is a concept that is abstract and difficult to see by eye directly, one example electric shock, but cannot see the movement of electric current so that students have difficulty by students. A computer simulation designed to improve the understanding of the concept of the workings of the dry cell (battery). This study was conducted to 82 students (aged 18-20 years) in the experimental group by learning to use the Dry Cell Microscopic Simulation (DCMS). The result shows the improving of students’ conceptual understanding scores from post test were statistically significantly of the workings of batteries. The implication using computer simulations designed to overcome the difficulties of conceptual understanding, can effectively help students in facilitating conceptual change.
