- ACORNS Pre is the average ACORNS pretest score for that teacher—scores ranged from 0 (worst) to 6 (best). ACORNS Post is the average ACORNS posttest score for that teacher. ACORNS Gain is the average gain in ACORNS score from pretest to posttest for that teacher (i.e., ACORNS Post–ACORNS Pre). Numbers in italics indicate a statistically significant increase. ACORNS Effect Size is a standardized expression of the effect of the curriculum mini-unit for a particular teacher. Positive means an increase, negative means a decrease. Higher effect sizes are better. For these data, an effect size of 0.30 or higher suggests that the curriculum mini-units affected gains in ACORNS score over and above the effects of the teacher. GAENE Pre is the average GAENE pretest score for that teacher—scores ranged from 0 (least accepting of evolution) to 80 (most accepting of evolution). GAENE Post is the average GAENE posttest score for that teacher. GAENE Gain is the average gain in GAENE score from pretest to posttest for that teacher (i.e., GAENE Post–GAENE Pre). Numbers in italics indicate a statistically significant increase. GAENE Effect Size is a standardized expression of the effect of the mini-unit for a particular teacher. Positive means an increase, negative means a decrease. Higher effect sizes are better. For these data, an effect size of 0.30 or higher suggests that the curriculum mini-units affected gains in GAENE score over and above the effects of the teacher (Teacher 13 did not administer the GAENE, hence the absence of data in those cells in the table)
