This paper reports the effect of task structure on two Y7 students’ performance in a pre-post testing situation. The tests consisted equal number of ‘tasks with confidence level’ and ‘tasks with safety-net’ structures. Two cases were analysed: i) one girl’s performance in eight weeks gap, and ii) one boy’s performance in two weeks gap. The boy’s performance was consistent and showed little effect from task structure. The girl’s performance seemed significantly affected showing progress in safety-net tasks which could be attributed to teacher’s feedback. Task structures uncovered different patterns of girl’s reasoning between the tests which was confirmed in interview.
