Science process skills students on cells and tissues concept during the covid-19 pandemic: how did it achieve?

Abstract

AbstractThe purpose of this study was to measure the achievement of students’ science process skills (SPS) on cells and tissues concept during pandemic. The research was conducted in January 2021 at high school in Depok City. The sampling technique used purposive random sampling.

The aspect that gets the least category is communicating (grade XII) and classification (grade XI). This can be influenced by the level of students’ understanding of the concept and scientific process, experience in observing, and doing all scientific process.
