Survey analysis of the 57 survey completers grouped by experience (n = 15 under five years, n = 16 five-to-ten years, n = 26 over ten years); Table 3 reports by-group paired t-test results such as Q19 gains of 0.6, 0.53, and 0.73. The article reports "consistent and statistically significant growth across all measured areas" for the over-ten-years group.

"Notably, teachers with over 10 years of experience demonstrated consistent and statistically significant growth across all measured areas, showcasing a deepening of their instructional practices and mentoring abilities."

q2 · i? · design · r2

Paired-sample t-test analysis of the novice group (n = 15, under five years of experience) found no statistically significant practice change; the article attributes this possibly to "the small sample size for novice teachers" or needing more time for pedagogical changes to manifest. Equivalence was not tested.

"The different results in growth trajectories suggest that while novice teachers perceived the LSVC PD as highly beneficial, statistically significant evidence of changes in their classroom practices was not identified."
