Abstract:

The aims of this study are to determine and compare the levels of scientific process skills of 5th and 8th grade students. The skills which were examined specifically for this research are as following: Observation, classification, measurement, recording data, establishing space and number relationships, predicting, identifying variables, interpreting data, inference, hypothesizing, modelling, and experimenting.   Research was conducted with a total of 200 students, 100 students at 5th grade and 100 students at 8th grade, attending to a middle school in the province of Kars. In this research the survey method was utilized. Science Process Skills Test (SPST) consisting of multiple choice questions administered to students of each grades to determine their level of science process skills. Data was examined by utilizing frequency and percentage distributions.   The findings show that the percentage of success achieved by the 8th grade students is higher than the 5th grade students. In addition, both 5th graders and 8th graders’ performance level for experimenting and establishing space and number relationships are lower compared to other process skills. Findings also showed that 5th grade students are better in recording data, and 8th graders are better in creating a model in compare to other science process skills.
