In this paper, another step towards students' attained curriculum evaluation is described. Earlier piloted tasks (think-aloud and eye-tracking) were transformed into a three-tier task shape.
First, the tasks were piloted to check for the understandableness of the multiple choice second tier. Later, they were evaluated in order to optimize the distractors as well as to check students' success-rate on the tests.
The students (N = 92) provided adequate feedback. The success rate decreased considerably from 48% to 15% when the second tier (explanation) was considered.
Based on the result, two distractors were replaced. This process produced a final test ready to be used on a broader sample.
