The aim of this study was to investigate The effect of skill level matching in cooperative dyadic interaction on learning of forehand table tennis skills in adolescent girls. Participants were selected convenience sampling form from 24 junior high school girls in Nahavand city and were randomly divided into two groups of Novice-Novice and Novice-Expert. Both groups performed five sessions of participatory dyad training with their respective arrangement (novice- novice, novice- expert) that each session consisted of 20 sets of 3-minute with a 1-minute rest time between sets. Using table tennis forehand shot accuracy test, the motor performance was measured in the pre-test, post-test, retention and transfer stages (Merely forehand performance with increasing throwing speed of ball thrower). The results showed that both Novice-Novice and Novice-Expert groups showed significant progress learning of forehand table tennis skills; Also, the Novice-Expert performed better in the post-test, retention and transfer stages than the Novice-Novice group. Therefore, Novice-Expert arrangement than Novice-Novice during participatory dyad training facilitates learning forehand table tennis skill.It revealed that novice-expert arrangement is more efficient in comparison to novice-novice arrangement as the former enjoys the benefits of using the optimal observational pattern (seeing a expert person), and offeres various challenges and strategies for the novice partner as a result of exercising with an expert partner. To conclude, novice-expert dyad practice promotes the speed of learning among table tennis learners.

The purpose of this study was to determine the effect of distribution of practice on the acquisition, retention with different intervals 1, 7, and also judgment of learning accuracy of forehand drive in table tennis. The 32 female student with 18- 24 years old that passed specialized table tennis unit, contributed as convicted. They randomly were divided to massed and distributed practice groups. The skill used in this study was the forehand drive. After pretest, the massed group practiced all 240 Trails in one session, and the distributed practice group practiced 60 trials per day on 4 consecutive days. After acquisition phase, Participants were asked to predict performance on the retention phase. Participants were asked, “what would you predict your average score on the first the retention test? “And then half of participants of each group contributed for a retention test 1 day later, half of other participants of each group contributed for retention test 7 days later. The data were analyzed by independent sample t test and two –way analysis of variants (ANOVA) with repeated test. The result showed significant differences between massed and distributed practice groups in the acquisition, retention (1, 7) test and also judgment of learning (p

The purpose of the present study was to investigate the effect of variability of attentional focus distance by self-talk on the learning of table tennis forehand in. After pretest, the participants performed 180 forehand strokes during 6 sessions with repeating the words “slightly rotation” in the internal focus group “slightly open” in the near external focus group, “over the net ” in the far external focus group, and each of the words “slightly rotation, slightly open, and over the net ” respectively in each 2 sessions in the increasing distance of attentional focus group. Control group performed without self-talk during acquisition phase. Retention test was performed 48 hours after acquisition test in the same situation without self-talk, and after break, transfer test was done by changing the direction of target (parallel forehand) without self-talk. The accuracy and the pattern of forehand strokes were measured by a 5 point-scale (Liao and Masters, 2001) and researcher-made scale, respectively) .According to the results of 2-factor mixed ANOVA, acquisition, retention, and transfer of forehand accuracy in internal focus of attention group were significantly lower than other groups (p<0.05).Furthermore, the effect of increasing attentional focus distance on acquisition of forehand pattern was significant. The effect of near external attentional focus on retention of pattern was significant. But transfer of stroke pattern in control group was significantly more than far external focus group (p<0.05). Thus, it is recommended to use self-talk by increasing attentional focus and near external attentional focus and not to use internal focus of attention to instruct forehand to novice adolescents.
