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.
q1 i? The study used domain-specific prior knowledge as a moderator and post-learning measures including mental effort and knowledge as dependent measures. → SIGNALING IN MULTIMEDIA LEARNING: THE INFLUENCE OF PRIOR KNOWLEDGE 2007

Descriptive note in the supplemental variable table. Variables marked with two asterisks, including the 15 verification items of "Domain-specific prior knowledge**", the knowledge test, and mental effort and related ratings, are designated as moderator or dependent measures. No results are reported in the provided text.
"** Variable used in the attached manuscript as moderator or dependent measure."
Discussion¶
Related Claims¶
- Prior knowledge and intervention condition predict repeated cognitive load and interest measures: prior knowledge lowers effort and difficulty and raises interest and understanding, and prompting groups perceive tasks as more difficult — related
- High experienced effort-by-complexity is not necessarily indicative of better learning outcomes — related
