Having developed an original e-learning web system that helps intermediate and advanced students to learn 1400 noun-verb collocations, we wished to identify those collocations which learners found consistently difficult to internalize. Participants were asked to choose a proper particle and a verb which matches a noun in a given sentence. We then analyzed the percentage of correct answers in order to identity those collocations which students struggled with. What becomes apparent is that they tend to make errors with particles, collocations which are difficult to conjecture vis-à-vis their meanings, or verbs which don't include their substantive original meaning. We intend to improve our web system by reflecting upon, and incorporating feedback from participants.
