The aim of this study was to investigate the effect of game-oriented exercises on motor development of overweight children with developmental coordination disorder. The research method was semi-experimental with pretest and posttest. 50 overweight children aged between 8 and 10 with developmental coordination disorder were selected and were randomly assigned to experimental (n=35) and control (n=15) groups after pretest. The experimental group participated in the protocol for 3 sessions per week during 3 months. MABC-2 test was used and SPSS 21 software was used for data analysis. The results of MANCOVA showed a difference between the experimental and control groups in at least one of the variables. Based on the results of one-way covariance analysis with a significance level of 0.05, there was a significant difference between the control and the intervention groups in motor development components and its subscales (hand speed, targeting and balance) and the experimental group got better scores. Therefore, it is recommended that the development of this disorder should be prevented in overweight individuals by designing different exercises and early intervention, and have a positive effect on their motor development.

The aim of this study was to compare observational models in learning motor task of receiving a volleyball ball and motor-cognitive task of juggling with 3 balls. The participants were 80 female students aged between 19 and 25. 40 subjects participated in each task. Participants were divided into 4 groups: novice model observation, expert, mixed and physical practice. All observational groups watched their own model via video tapes. In this study, some acquisition phases, retention and transfer tests were carried out in all two tasks. In acquisition phase, data were analyzed with ANOVA with repeated measures and in retention and transfer tests one-way ANOVA test and proper post hoc tests were used (P<0.05). In the acquisition phase, observation of expert-novice model in the motor task was better than the other groups but this predominance was not significant. But in the retention and transfer tests, observation of this model had a significant predominance. In the cognitive-motor task, the observation of novice model was better than the other groups during the acquisition phase, retention and transfer tests but this predominance was not significant in the transfer test. Finally,based on the results of the present study, it is suggested that various modeling methods should be used to learn different tasks.

Children's development is shaped based on a combination of environmental, organism, physiological and genetic factors. Recent researches on the development of children and toddlers convincingly show that the best growth level happens in a motivating environment and a powerful support. This study aimed at evaluating the effect of an environment affordance intervention on social development of toddlers aged between 24 and 42 months. The sample included 46 healthy toddlers aged between 24 and 42 months in Ghoochan city who were randomly selected by multi-stage cluster sampling methods. The subjects were assigned to three groups: experimental (n=16), kindergarten (n=15) and control (n=15). The experimental group was placed in an afforded environment for 36 sessions (3 months). To examine toddlers' home environment and afforded environment of experimental group, the Affordances in the Home Environment for Motor Development– (AHEMD) was used for motor development and Vineland Scale was applied for social development. Data were analyzed using univariate analysis of Covariance (ANCOVA). The findings showed no significant differences in social development among the groups (P=0.963). The results indicated that environment affordances had no effects on toddlers' social development in the experimental group. Therefore, the present study concluded that environment affordance did not influence toddlers' social development aged between 24 and 42 months.
