This research is about the influences on the measurement effect from item form and its testing method. As a result of comparison between the Short-Answer form with the Multiple-Choice form, the item difficulty parameters of Short-Answer form were found to be higher than Multiple-Choice form, but no clear differences were shown in the item discrimination parameters between these forms. Moreover, it was found that the measuring ability of the test hardly changed when replacing the item form. Furthermore, it was found that when the suitable alternatives were provided, the Multiple-Choice form was expected to show higher discrimination power than the Short-Answer form. It was also found that when using testing methods with more grades of scoring, the item information will be increased.
