This study compares the effectiveness of multiple-choice (MC) and constructed-response (CR) study tasks both with feedback. Graduate students (n = 46) completed a computer-delivered vocabulary lesson on instructional design terms followed by cued recall and recognition posttests. The CR study task was significantly more effective than the MC study task on the recognition posttest, but not on the cued recall posttest. Designers should consider expanding the use of CR study tasks in similar instructional cases. (Contains 2 tables and 1 figure.)
