Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Across the three editions of Multimedia Learning, the number of experimental comparisons grew from 45 (2001) to 93 (2009) to 201 (2021), and the number of principles from 7 to 12 to 15. → Richard E. Mayer 2024

Descriptive tally in Table 3 of the research base across three editions of Multimedia Learning: edition 1 (2001) lists 45 experimental comparisons and 7 principles, edition 2 (2009) lists 93 and 12, edition 3 (2021) lists 201 and 15. The text states the lab has "generate[d] 15 evidence-based principles based on more than 200 experiments".

"Starting with our first multimedia learning studies in 1989, we have been able to generate 15 evidence-based principles based on more than 200 experiments conducted by my colleagues and me."
