“…One especially robust desirable difficulty is the application of tests (also: testing, testing effect, retrieval practice, test-enhanced learning, and learning/practice tests ): Taking (learning) tests on previously studied materials increases long-term learning compared to easier and more passive re-reading tasks or compared to note-taking as a stronger control task—even concerning a multitude of difficult, complex, and curricular subjects in realistic learning contexts (e.g., McDaniel et al, 2007 ; Dunlosky et al, 2013 ; Rowland, 2014 ; Karpicke and Aue, 2015 ; Adesope et al, 2017 ; Batsell et al, 2017 ; Rummer et al, 2017 ; Yang et al, 2021 ). These beneficial effects of tests were, among others, found for different types of learning materials (e.g., factual information, vocabulary, conceptual information, longer scientific textbook paragraphs, traditional (live) lectures/lessons, and recorded e-lectures/video-presentations) and for different types of test questions (e.g., multiple-choice questions, short-answer questions, fill-in-the-blank questions, comprehension-based questions, application-based questions, transfer questions, and inferences; e.g., Roediger and Karpicke, 2006 ; McDaniel et al, 2011 , 2013 ; Dunlosky et al, 2013 ; Rowland, 2014 ; Khanna, 2015 ; Jing et al, 2016 ; Adesope et al, 2017 ; Iwamoto et al, 2017 ; Heitmann et al, 2018 ; Feraco et al, 2020 ; Yang et al, 2021 ). Moreover, tests were beneficial in varying (face-to-face or online) settings (e.g., laboratories, universities, classrooms, and at home/outside of class) and for students of different age groups (e.g., elementary school students, high school students, and university students; e.g., McDaniel et al, 2007 , 2011 ; Roediger et al, 2011 ; Rowland, 2014 ; Adesope et al, 2017 ; Yang et al, 2021 ).…”
