*3.1.1 Information literacy test (ILT)*

A multiple-choice knowledge test [36] was used, comprising 40 multiple choice items with four options and one correct, yielding a point per item. For analysis purposes, ILT items were divided into subscales by five ACRL 2000 information literacy standards (A1—information needs identification, A2—information search, A3—information evaluation, A4—information use, A5—ethical/legal issues) [10]. Similarly, ILT items were classified into one of the three cognitive categories (B1—remembering, B2—understanding, B3—applying), simplified from the Bloom's Taxonomy [37].
