This paper presents an approach to information literacy instruction in colleges and universities that combines online and classroom learning (Blended Learning). The concept includes only one classroom seminar, so the approach presented here can replace existing one-shot sessions at colleges and universities without changes to the current workflow. By adding online materials to a classroom seminar, comprehensive information literacy instruction can be delivered in a time-efficient way. To make instruction more time efficient, each student received individual recommendations on which of the online materials he/she is supposed to complete based on a pretest. Results of an evaluation study with 64 psychology students point to significant increases in information literacy and indicate that most students accepted and followed the recommendations. The findings also show that students who completed materials beyond the recommendations did not show a greater learning progress than those following the recommendations, closely emphasizing the adequacy of the recommendations provided.
