Background: Observational learning is an effective pedagogical approach that can be used as a method to improve motor skill acquisition and also a useful instrument to promote psychological variables such as self-efficacy by emphasizing the motivational aspect. Although, little research is known about the model type and the observation conditions which will optimize learning. Aim: This study aimed to clarify the effect of using a combination of ideal model-observation and self-observation on self-efficacy and learning the forehand service of table tennis. Materials and Methods: Forty females were assigned to one of four experimental groups. All groups received the same instructions concerning how to perform the task, filled out a self-efficacy questionnaire, and then performed 10 pre-test trials. The acquisition phase included six sessions. The retention test was done 72 hours after the last acquisition session. Mixed ANOVA with repeated measures and Bonferroni post hoc tests were conducted, and one-way ANOVA was used to determine group significant differences. Results: The results indicated that observing the combination of skilled and learning models led to the highest self-efficacy for learning, compare with other experimental models. Also, significant learning of the task was shown in the acquisition phase in which the performance of all three experimental groups was clearly superior to the control group. Although in this phase there was no significant difference between the performances of two groups of combined skilled-learning and skilled. The results of the delayed retention test indicated that the performance scores of the combined skilled-learning group were significantly higher than the other three groups. Also, in this phase, the difference between the combined skilled self-observation and control or skilled groups was not significant. Conclusion: Demonstrating a skilled model is the most popular type of observational learning among the instructors and physical education teachers, it is suggested that adding a learning model to that leads to better performance and enhancing the self-efficacy.

Purpose: Digital literacy fosters social advantages such as chances to interact with others and forge and develop social relationships by enabling online activities and leading to online social capital development. This study investigated the relationship between digital literacy and online social capital. Methodology: The research method is quantitative, descriptive, cross-sectional, and correlational. Participants comprised 754 (520 female and 234 male) students of Tabriz universities during the months of June and August 2023, who were randomly selected from among those willing to cooperate and responded to the Digital Literacy Questionnaire (Ng, 2012) and Online Social Capital Questionnaire (Duradoni et al., 2022). Data were analyzed using confirmatory factor analysis and structural equation modelling with SPSS version 27 and Amos Graphic version 24 software. Findings: Utilizing confirmatory factor analysis, the factorial structure of the research instruments was examined. The digital literacy questionnaire's three-factor structure and the online social capital questionnaire's two-factor structure were confirmed. The GFIs were higher than 0.9, and the RMSEA was below 0.08. The fit indices indicate that the structural model describing the relationship between digital literacy and online social capital is supported. The standard weights of the confidence and connectedness dimensions of the relationship between digital literacy and online social capital were 0.42 and 0.48, respectively (p<0.05). Conclusion: Digital literacy encompasses social, cognitive, and emotional skills in addition to technical ones. Therefore, digital literacy is multidimensional and lays the foundation for a new, constantly evolving style of online relationships and interpersonal connections. Higher levels of digital literacy and its components provide individuals with the ability and opportunity to convert their network of relationships into other forms of capital, obtain and provide support in the virtual space, and engage in emotional exchange, group leisure time, counselling, and collaboration. These competencies form the basis of online social capital.
