Abstract
The study evaluated the role of custom-developed dynamic simulations on
students conceptual understanding of chemical equilibrium. An ANCOVA analysis
showed posttest scores were significantly higher for the experimental group
(Mpost. = 7.27, SDpost = 1.387) relative to the control group (Mpost. = 2.67,
SDpost = 1.371) after adjusting for pretest scores: 𝐹 (1,24) = 71.82, 𝑀𝑆𝐸
= 1.497, 𝑝
= 0.03, 𝜂𝑝2
= 0.75, 𝑑=
3.33. Cohen’s d was converted to an attenuated effect size d*. The adjusted
(for pretest scores) group mean difference estimate without measure error
correction for the posttest scores and the pretest scores was 4.2 with a
Cohen’s d = 3.04. Alternatively, the adjusted (for pretest scores) group mean
difference estimate with measurement error correction only for the posttest
scores with measurement error correction was 4.23 with Cohen’s d = 3.07. Effect
size indicates a positive correlation between the intervention and students’
conceptual understanding.
