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

Abstract

The 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. SPS tested consist of 7 aspects (observing, applying concepts, interpreting, asking, communicating, classifying, and concluding). Data collection using an essay test with 16 questions and teacher-student interviews. The instrument was validated by five expert validators and calculated with the Aiken's V formula reaches 0.74 (valid) and the reliability test value with Cronbach-Alpha reaches 0.81 (reliable). The non-parametric normality test reach 0.361 (sample is normally distributed). The non-parametric Mann-Whitney test reach 0.011 (hypothesis accepted; there is a difference in achievement between grade XI and XII). The results of the survey showed that the students' SPS were in the moderate (grade XII) and less category (grade XI). The easiest aspect of SPS in both is the questioning aspect. 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.
