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.
q3 i? Students achieving perfect domain knowledge scores rose from 79% before CVS instruction to 100% after, despite no expository instruction on the causal variables. → Eva Erdosne Toth 2000

q3 · i? · design · r2
Pre/post forced-choice domain knowledge test in the classroom study (which variable level makes the ball roll farther). The article reports 79% perfect scores before and 100% after instruction, t(71) = 4.3, p < .0001, with no direct instruction on the ramps variables.
"Whereas 79% of the students provided correct answers to all three questions on the domain knowledge test prior to CVS instruction, 100% of the students got the maximum score after instruction,t(71) = 4.3, p < .0001."
Discussion¶
Learner Variables¶
- Prior Knowledge — outcome: instruction changes it
Related Claims¶
- Classroom expository CVS instruction dramatically increased fourth graders' CVS performance in individual hands-on interviews — related
- Children gained domain knowledge of variable effects indirectly from running experiments, with mixed condition differences on individual variables — related
- Students' experiment-evaluation strategies shifted toward correct CVS after instruction, though 23% still used incorrect strategies — related
