Preregistering experiments increase credibility of results and limit questionable research practices (Nosek et al., 2018). Furthermore, standardizing pre‐ and post-test measures raises comparability between studies. For evaluations of the relative effectiveness of digital learning games for learning outcomes, standardized tests are not always available. These tests should then be developed in collaboration with experts (e.g., cognitive scientists, psychologists, or teachers), validated, and tested for reliability. To further standardize timing of measurements, we suggest conducting the pre-test a week before the intervention to avoid effects of testing on experimental results and to generate a non-biased baseline.
We also presented our own digital educational game, Entropy Mastermind, for fostering students’ intuitions about entropy. Lastly, we discussed limitations of DGBL and suggested ways to overcome potential complications. With PISA’s focus for 2024 being on the “ability of students to learn in a digital world,”1 the importance of digital learning, including digital game-based learning … Read More
