Analysis of gain scores, also called change scores or difference scores, was used to test for the effect of treatment; unpaired Student’s t-tests were used to compare the post- and pre-test difference chatroulette incelemesi in scores between the control and intervention groups (Allison, 1990; Ragosa, 1995; Oakes and Feldman, 2001). Since baseline differences between groups existed at pre-test, analysis of covariance (ANCOVA) was applied as an alternative to analyze the scores. We used the post-test gross motor and pre-literacy scores as the dependent variable, the control/intervention group as independent variable and the pre-test score as covariate. ANCOVA focuses on differences between the groups at post-test while holding constant pre-test differences. In all the analyses, the level of significance was set at p < 0.05. Statistics were performed by using STATA/MP 12.1.
Performance
During the baseline, CG and you can IG did not show one significant distinctions (p > 0.05) in terms of sex, chronological ages, pounds, height, Body mass index and terrible engine profile, since revealed in Dining table 2.
After the experimental period, CG did not exhibit any significant difference in locomotor, object-control skills or QGMD scores. In contrast, the intervention group showed significant differences (p < 0.001) from baseline to post-test in gross motor skills. As shown in Figures 2, 3, locomotor, object-control skills and QGMD increased by 24.4%, 9.7%, and 10.4%, respectively, in IG. Moreover, the mean difference of QGMD between pre- and post-intervention in IG was significantly higher than that in CG (11.3 vs. 3.2, p = 0.0082). These results confirmed preliminary results previously reported (Battaglia et al., 2018). The same result occurred for the locomotor skills, showing a significant mean difference of 2.5 in IG compared to the 0.7 in CG (p = 0.0050). The analysis of covariance confirmed the positive effect of the intervention in the improvement of children's gross motor skills, starting even from different pre-test scores.

Figure 3. Score of locomotor and object control skills after 16 weeks of physical education program. ??? p < 0.01, compared with pre-test.
Dining table 3 displays that exact bits of locomotor and you will target handle skills didn’t escalation in the latest handle group after the experimental period, when you are an extremely extreme raise try noticed in every item into the IG responding so you’re able to PEP.
All the pre-literacy experience significantly increased inside IG pursuing the input months, during CG only the level of problems into the naming from items significantly decreased (see Dining table 4). However, the analyses away from acquire score and ANCOVA don’t reveal one high impression in the input between CG and IG.
Talk
This study investigated the effects of a specific PEP on the outcomes of fundamental motor and pre-literacy skills concerning visual analysis and spatial orientation abilities in a sample of preschool children from Palermo. Gross motor development was expressed as a composite score of a set of fundamental motor skills across the two gross motor skill domains. We observed a positive effect of PEP on gross motor development in the studied population. In particular, IG showed a significant increase in both locomotor (p < 0. These findings are consistent with those of previous studies that investigated the effect of PE on preschoolers' gross motor skills (Derri et al. For instance, Derri et al. Analysis of the covariance and gain scores confirmed the positive effect of our intervention in the rise of children's gross motor skills, even starting from different pre-test scores.
The aid of acquire score otherwise ANCOVA could have been mostly contended in the past from the investigation away from pre-test/post-decide to try models. Since ANCOVA is suitable just for randomized managed products and you can is bias leads to non-similar teams or observational patterns, the research out of obtain results offers up suitable, unbiased testing for some search patterns (Ragosa, 1995). About absence of randomization, when baseline differences between groups are present, change-score patterns produce quicker biased prices (Allison, 1990). Considering QGMD score suggested from the manual’s guidelines, we learned that IG enhanced the brand new disgusting motor efficiency out-of mediocre to help you over mediocre compared with CG, and this did not tell you people relevant changes. At the same time, the organization of just one lesson a number of sandwich-phase (social-heat up, main, cool-down-opinions stage) try the right cure for increase kid’s participation.
