q3 i? About half the children in each condition designed at least seven of eight unconfounded experiments after training, with no condition difference. → Triona 2003

q3 · i? · causal · r2

Individual-level analysis defined a good experimenter as designing at least seven of eight unconfounded experiments after training. The article reports "Fifty percent (23/46)" for physical and "52% (24/46)" for virtual, χ2(1, N = 92) = .04, ns.

"Fifty percent (23/46) of the children trained with physical materials and 52% (24/46) of the children trained with virtual materials were classified as good experimenters."

Related Claims¶

• Children's confidence in experimental conclusions increased after training and was higher for unconfounded than confounded experiments, with no training-condition differences — related
• Children gained domain knowledge of variable effects indirectly from running experiments, with mixed condition differences on individual variables — related
• Both physical and virtual training conditions produced equal gains in children's explicit verbal knowledge of the control of variables strategy — related
• Physical and virtual instructional materials are equally effective for teaching fourth- and fifth-graders to design unconfounded experiments when instructional method is controlled — related
• Instruction increased robust CVS use — designing unconfounded experiments plus providing a CVS rationale — in individual interviews — related
• CVS skill is the strongest predictor of performing valid (unconfounded) experiments in simulation-based inquiry — related
