q2 i? After an 8-week implementation, the experimental group's PRT posttest scores were significantly higher than the control group's (U=46.500, p=.002). → Şen 2017

q2 · i? · causal · r2

Mann-Whitney U comparison of posttest Proportional Reasoning Test scores in a quasi-experimental pretest-posttest control group study (n=16 per group). The average rank was 21.59 for the experimental group and 11.41 for the control group, "in favor of the experimental group (U=46.500, p=.002<.05)".

"This result shows that there was a statistically significant difference between the PRT posttest scores of the experimental and control groups in favor of the experimental group (U=46.500, p=.002<.05)."

Discussion¶

Learner Variables¶

• Proportional Reasoning — outcome: instruction changes it
