IDENTIFYING STUDENT’S LEARNING OBSTACLE OF SHIFT EQUILIBRIUM CHEMISTRY BY USING WORKSHEETS

The pupose of study was to identifying student's learning obstacle of shift equilibrium chemistry by using worksheet. Fourty students in eleven grade participated in study. The student worksheet consists of two learning activities. In first stage, students observe the animated videos provided related to factors of shift equilibrium chemistry are pressure, volume and temperature. And second stage, they were answer the questions in worksheet based on observing the animated videos. Data were collected based on student answers on the worksheet. The written responses were analysed to identifying student' learning obstacle. Results indicated that students had difficults explains the reasons for the shift in chemical equilibrium caused by pressure, volume and temperature factors. The obtained results underline that the worksheet was an effective method to identifying student's learning obstacle.
