  1. F (also known as value of F-distribution) describe the probability distribution, notably in the analysis of variance. P (also known as p-value) means statistical significance in the probability. ηp2 (partial eta-score) is an effect size that is measure of the magnitude of a phenomenon in statistics. Data are shown as mean (standard deviation). SS Self-study, SW Summary writing, AW Argumentative writing. For each group, total scores, rote-memory item scores and transfer type item scores are given. Gender and age were adjusted
