Abstract
Choosing the right items for the final assessment test of an educational module as part of an educational program is a demanding task, considering the population to be examined, the educational goals to be evaluated and the comparability of the results over different groups of examinees in different cycles of the educational program.
Ιn this paper, we present a process framework for analyzing interim assessments and selecting the right items for the final assessment of an educational module. The interim assessment tests are analyzed using Item Response Theory and the Items' Information Function (IIF) are determined. The criteria for selecting items are their peak information values, their distribution over the ability scale θ and their coverage of the educational goals set. The re-used items are transformed to pseudo-open ended questions and graded according to educational goals achievement. Application of the process framework on two university modules showed that the overall information of the tests is increased from the interim tests to the final test while the average student gradesremained at the same levels.
