Abstract
This study aims to analyze pre-service teachers^ science process skills by examining indicators of basic science process skills through inorganic chemistry experiments on the properties of alkaline earth elements. This study uses a quantitative descriptive method. The research sample was 30 students of chemistry education of batch 2020 who took the structure and reactivity of inorganic compounds. Data collection techniques are carried out by observing practical activities. The instrument used was a science process skill observation sheet with a skill score used was a Likert scale. The results showed that the science process skills of students with a percentage of 70.67% were in the medium category. The percentage details for each indicator of science process skills include the ability to observe and ask questions with a percentage of 77.50% and 75.00% in the high category. The scores for making hypotheses and planning experiments in the medium category were 58.33% and 62.50%. The indicator uses practical tools and materials with a percentage of 75.83% in the high category, applying the concepts that have been studied in the medium category with a percentage of 70.83%. The indicator scores for classifying and predicting are 80.00% in the high category and 69.58% in the medium category. The students^ ability in interpreting data and communicating were 78.33% in the high category and 58.75% in the medium category. Based on these findings, it can be concluded that the inorganic chemistry practicum activities that have been carried out can analyze students^ science process skills. This study found several recommendations, first- science process skills must be applied in every science lesson, especially for chemistry education lecturers. Second- the science process skills of prospective teacher students must be improved on the indicators of making hypotheses and communicating by being trained intensively in each learning process.
