Are mastery learning strategies beneficial for developing problem solving skills?

The purpose of the present study was to investigate instructional methods appropriate for developing problem solving skills (PSS) in a paramedical course. Three instructional methods were compared: Frontal Lecture Strategies (FLS), Mastery Learning Strategies (MLS) and Experiential Mastery Learning Strategies (EMLS) in which feedback corrective procedures were embedded within experiential learning situations. Results showed that FLS produced the highest scores on Lower Mental Process subtest while EMLS yielded the highest scores on all measures of problem solving skills. Several implications of this study for future research are suggested and discussed.     

Factors Associated with Teenagers’ Willingness to Volunteer with Elderly Persons: Application of the Theory of Planned Behavior (TPB)

The purpose of this study was to investigate the factors associated with teenagers’ willingness to volunteer with elderly persons using an expanded model of the Theory of Planned Behavior (TPB). Participants consisted of 258 ninth-grade students at a large high school in the northern part of Israel. Participants completed a structured questionnaire consisting of 52 items, which examined their attitudes, subjective norms, perceived behavioral control, past behavior, personal identity, and perceived moral obligation. Their willingness to volunteer with elderly persons was assessed using six vignettes, varying in the severity of the elderly person's health and functional conditions described. Additionally, the students’ sociodemographic variables were examined. Overall, students’ willingness to volunteer with elderly persons was low; however, it increased when the elderly person in the vignette was described as relatively healthy. Statistically significant relationships were found between willingness to volunteer and personal identity, as well as between willingness to volunteer and attitudes toward volunteering with elderly persons. A statistically significant but moderate relationship was found between willingness to volunteer and subjective norms. Multiple regression analyses showed that attitudes, subjective norms, and personal identity were the main predictors of willingness to volunteer with elderly persons, explaining 58% of the variance. The expanded model of the Theory of Planned Behavior provided an appropriate framework for understanding the factors associated with teenagers’ willingness to volunteer with elderly persons. Our findings stress the need to develop educational intervention programs regarding gerontologically-related subjects and to disseminate them among the population in general, and among youth in particular.

Decision-making skills and deliberate practice in elite association football referees

We examined sport expertise as a function of role. In study 1, referees were better than players in a video-based decision-making task. This provides evidence that there are role-specific skills within one domain or sport. In study 2, we examined the training activities that could be influential in the development of skills in sports officials. Elite association football (soccer) referees retrospectively reported time spent in and perceptions of training activities for three periods: their first year of formal refereeing, 1998 (before formal training programmes were available), and the current year (2003). This allowed us to examine an area of skill with a limited culture of practice, where performance simulations with direct feedback are usually not feasible. The results showed that referees specialize early and, as they develop, they engage in greater volumes and types of training. Competitive match refereeing is considered a relevant activity for skill acquisition that does not fit Ericsson and colleagues' (1993) original definition of deliberate practice. Our findings indicate that actual performance is a significant activity for skill acquisition and refinement.     

Reducing adolescents' involvement with relational aggression: Evaluating the effectiveness of the Creating A Safe School (CASS) intervention

This study examined the effectiveness of a comprehensive, school‐based intervention program, Creating A Safe School (CASS; The Ophelia Project) designed to reduce relational aggression (RA) and relational victimization (RV). Sixth‐grade students (N = 406) were surveyed before and after the intervention. Program effects were tested using a repeated‐measures design. Results revealed significant reductions in RA and RV among students who reported initially high levels of involvement. Findings also showed that decreasing approval of RA accounted for a significant amount of variance in changes in RA between pre‐ and posttest. These results provide initial evidence of the effectiveness of the CASS intervention model in reducing RA among early adolescents. © 2010 Wiley Periodicals, Inc.     

Esports players,got muscle? Competitive video game players’ physical activity,body fat,bone mineral content,and muscle mass in comparison to matched controls

BackgroundEsports players, like traditional athletes, practice for long hours and, thus, are vulnerable to the negative health effects of prolonged sitting. There is a lack of research on the physical activity and the health ramifications of prolonged sitting by competitive players. The purpose of this study was to investigate activity levels, body mass index (BMI), and body composition in collegiate esports players as compared to age-matched controls.MethodsTwenty-four male collegiate esports players and non-esports players between 18 and 25 years of age signed a written consent to participate. Physical activity was examined using daily activity (step count) with a wrist-worn activity tracker. A questionnaire assessing physical activity was also administered. Secondary outcomes included body-fat percentage, lean-body mass, BMI, and bone mineral content measured using dual X-ray absorptiometry.ResultsThe step count in the esports players was significantly lower than the age-matched controls (6040.2 ± 3028.6 vs. 12843.8 ± 5661.1; p = 0.004). Esports players exhibited greater body-fat percentage (p = 0.05), less lean body mass (p = 0.003), and less bone mineral content (p = 0.03), despite no difference in BMI between the esports and non-esports players.ConclusionAs compared to non-esports players, collegiate esports players were significantly less active and had a higher body-fat percentage, with lower lean body mass and bone mineral content. The BMIs showed no difference between the 2 groups. Esports athletes displayed significantly less activity and poor body composition, which are all correlated with potential health issues and risk of injury. BMI did not capture this difference and should not be considered as an accurate measure of health in competitive esports players.
