Thanks Elizabeth for starting this. It's much appreciated & I hope it grows into a SIG
Tim & Elizabeth, hopefully I can shed some light on the findings of the Meo & Martí-Ballester (2020) paper. There's a large & growing body of research on the effects of tests & other similar strategies collectively known as retrieval practice*. The principle is that retrieval practice is a more effective & efficient way to strengthen memorised ideas, concepts, processes, compared to strategies such as re-study/re-reading. The evidence is so strong & the effect sizes so large that a number of researchers have acquired funding & established campaigns to promote retrieval practice, as well as 5 other strategies, to students, teachers, & instructional designers, e.g. https://www.learningscientists.org/downloadable-materials & https://www.retrievalpractice.org/
With this in mind, my take on the Meo & Martí-Ballester (2020) paper is that it doesn't establish a causal relationship between the testing & students' academic performance & an experimental design would be necessary to do so. However, I think that the abundance of evidence that retrieval practice is effective across a wide variety of disciplines, ages groups, & contexts leads me to believe that we'd likely see similar results had the present study incorporated an experimental design.
*To give you an idea of the sheer quantity of research on retrieval practice, here are the results from a search for one of the leading researcher's names, Jeffrey Karpicke in my bibliography manager:
