Finding the best teaching method is an issue that has attracted the attention of many researchers, researchers in behavioral sciences and sports today.. In order to discuss this, the aim of this study was to investigate the effect of TGFU, combination, and SE on individual and team creativity in comparison with the traditional method in futsal games. The statistical population of this study was all children aged 9-12 years in Ahvaz (M age= 10.74 and SD= 1.42). The interventions were designed for futsal skills, so four groups of Participants (20 people in each group) practiced SE, TGFU, combination and linear methods. The test of team and individual creativity was performed using film analysis. Exercises were presented for two months in 16 sessions, one and a half hours each. The results showed that for individual creativity in the post-test, differences between groups were not significant for inappropriate actions but significant for appropriate actions. Also for creative and original actions as well as team creativity TGFU, combination, SE and linear groups had the most progress, respectively. In all variables, the difference between TGFU and linear (p <0.05) and combination and linear (p <0.05) was significant. The results of this study showed the effectiveness of the TFGU and combined methods compared to the linear method, which can be used in schools and kindergartens..

The aim of this study was to determine the effects of errorless practice on learning an aiming skill in mentally retarded adolescents. 40 mentally retarded adolescents were assigned to four practice groups based on intelligence quotient and working memory capacity. The task was to throw basketball mini balls into a target with concentric circles. The practice of groups was different from each other. The subjects performed 200 practice attempts in 5 practice blocks in the acquisition stage. Single task and dual task tests were implemented immediately, with 24-hour latency and one-week latency. The secondary task involved counting even numbers forward. The results showed that the groups with the least error and the least involvement in work memory during the practice outperformed other groups in acquisition stage, the single task test and dual task test. The findings of this study were consistent with the Adam's closed loop theory, the reinvestment theory, and the estimates of the challenge point framework regarding errors in the acquisition stage, but they were contradictory with the estimates of the schema theory. These findings also provided evidence to support the claim of the challenge point framework and the reinvestment theory about special individuals (mentally retarded).

Aim: This study aimed to determine effect of self-control of task difficulty on accurate and movement pattern golf putting. Methodology: Thirty novice undergraduate students (14 Female and 16 male; average age 21.1 ± 1.64 years) were quasi-randomly assigned to two groups. Before performing each trial during the acquisition phase, the self-control group was told they could choose any of the pre-set distances from the target: (25, 50, 75, 100, 125, 150, 175 and, 200 cm). Each self-control participant’s practice schedule was served as the predetermined practice schedule for each corresponding yoked participant. Participants practiced eight blocks of 10 trials. To analyze the radial error (in acquisition and tests phases) and the movement pattern score (in tests) mixed variance analysis with repeated measures on the last factor was used. The movement pattern score in acquisition phase was analyzed using t test. Results: Based on the results, radial errors across different groups in the acquisition phase did not vary, but the radial error of the self-control group in retention, single task transfer and dual-task transfer tests was lower compared to the yoked group (ps < 0.001). In acquisition and test phases, the golf putting movement pattern was better than that of yoked group (ps < 0.001). Conclusion: The efficacy of self-control of task difficulty is explained with reference to the challenge point framework.

The Purpose of this investigation was to study the effect of variability of practice and age on retention and transfer of the over-arm throwing accuracy in children. Khalajy and Shafizadeh’s (1383) test of over-arm throwing accuracy was adjusted and used in this study. 48 right-handed female children (16 children in each age group of 4, 5 and 6 years old) were selected voluntarily. Each age group was divided into the variable and constant practice groups according to their pretest scores. The variable group practiced with different target sizes whereas constant group practiced only with one target size. Acquisition phase lasted 3 days; each day included 4 blocks of 6 trials with their right hand. The collected data from acquisition phase, retention test, and immediate and delayed transfer tests were analyzed by mixed factorial ANOVA and Tukey follow-up test. The results showed no significant difference between constant and variable groups in retention test (P>0.05). But in immediate and delayed transfer tests, variable group outperformed constant group (P
