Abstract
Many studies have shown the effectiveness of verbal instructions and observational training on the improvement of children’s motor skills; however, there is not enough information about the simultaneous effects of these two variables. The aim of this study was to investigate the effect of attention instructions during observation of the model on gaze behavior and accuracy of overarm throwing in children. 24 children 7 to 10 years of age with normal growth selected purposefully and randomly divided into two internal and external attentions during modeling groups. Training in both groups included observation 10 times skilled model overarm throwing’s film with eye movement recording, with the difference that before it each group received its own instruction. The results of mix-ANOVA and paired and independent t-tests showed that both groups showed a significant increase from the pre-test to post-test in the accuracy (p=0.001; p=0.001) and duration of the quiet eye (p=0.005; p=0.001) of overarm throwing. In the post-test, the external attention during modeling group compared to the internal attention during modeling had significantly higher accuracy (p=0.01) and longer quiet eye duration (p=0.001). Also, the external attention during modeling had more percentage viewing time to relevant external cues (ball and trajectory). Therefore, directing visual attention to movement effect of observed pattern cause improvement in motor performance and visual-motor expertise in children.

Abstract
This research has been conducted with the aim of identifying the effective factors and barriers to sustainable employment of sports science graduates in Iran and within the framework of a qualitative approach.The statistical population were experts who were aware of the research topic. Data collection was through in-depth and semi-structured interviews, which reached theoretical saturation after 16 interviews. To measure validity, transferability and verifiability, research findings were presented to the participants and their points of view were applied. The intra-subject agreement method was used for reliability, which was reported as 0.82. The findings related to effective factors indicated 68 main concepts and 5 subcategories(Employment skills, curriculum, needs assessment, sports industry development, motivation and support) and the findings related to effective barriers indicated 27 main concepts and 5 subcategories(policy and planning, economic and financial, legal, technological, cultural and social).Therefore, Paying attention to the quality of the employability skills of sports science students, including personal, technical and professional, general skills and coordination between higher education policies, employment, science, technology and economy are of great importance. What is necessary for this goal is to reform employment policies, develop the sports industry, target financial policies, and encourage employers to use sports science graduates more.
