A comparative study of three teaching methods on student information literacy in stand-alone credit-bearing university courses

1 Three teaching methods, applied to credit-bearing information literacy (IL) university courses, were evaluated and compared. The effects of lecture-based (LBL), project-based (PjBL) and problem-based learning (PBL) were investigated using the information literacy test (ILT) as an assessment tool, with regard to the total ILT score, specific IL contents according to the five ACRL standards, and students’ mental skills according to the Bloom’s cognitive categories. While all three teaching methods showed a significant improvement in the ILT post-test, the active-learning groups of PjBL and PBL scored significantly better than the LBL group. The most notable positive difference was observed in students’ effective access to information related to database searching skills, in the intellectual property/ethics issues, and in the cognitive category of comprehension. The PjBL and PBL post-test results did not differ significantly, indicating that both active learning methods resulted in similar improvements of students' IL.
