The results indicated that students’ ability to solve the tasks is increasing from task 1 to task 4 from the aspect of accuracy (M=6.48, SD=0.432 to M=7.80, SD= 0.190) but slightly decrease for task 4 for quality (M=5.82, SD=0.881 to M=7.52, SD=0.789 for task 1 to 3, and M=7.16, SD=0.666 for task 4). The findings of the present study might be useful to lecturers and teachers in helping them to plan interventions in enhancing students’ ability to solve tasks at different levels
