Abstract

This article aims to explain the content and implementation of online biology learning materials during the COVID-19 pandemic in SMA / MA / SMK. Face-to-face learning that is transformed into online learning has a profound impact on the content and amount of material taught by teachers to students. Even with the implementation of the emergency curriculum which reduces some basic competencies in one subject, there are still materials that are not conveyed by the teacher for several reasons. This is due to the selection of essential materials, allocation of time, facilities and media, as well as student learning fatigue using online platforms.

Abstract

Biology is a subject that bridges students' knowledge about this pandemic period, where this subject must present knowledge about viruses. In fact, the curriculum designs material that is very detailed and thoroughly discusses viruses found at the SMA / MA / SMK level, but the very minimum requires teachers to evaluate psychomorphic learning related to the application of healthy living habits and preventive efforts to campaign against viruses. Through this article, it will be explained how important psychomotor assessment of this virus is, where the condition of students must first have the competence and do real practicum in preventing virus diseases, especially COVID-19. This article is the result of observations on the implementation of psychomotor assessment, literature review, and documentation studies that give rise to ideas on the importance of psychomotor assessment of virus material in students. Virus material is very important to be presented in biology learning with consideration of a very wide coverage of material (virology), contextual material, the material as a design for health education indicators, and as an indicator design with epidemic response education.
