The impact of Nintendo Wii to physical education students' balance compared to the traditional approaches

The purpose of this study was to determine whether there is a difference between an exergame-based and a traditional balance training program, in undergraduate Physical Education students. Thirty two third-year undergraduate students at the Democritus University of Thrace were randomly divided into two training program groups of 16 students each, a traditional and a Nintendo Wii group. The two training program groups performed a specific balance program for 8 weeks, two times per week, and 24 min per session. The Nintendo Wii group used the interactive games Wii Fit Plus of the Nintendo Wii console, as a training method to improve their balance, while the traditional group used an exercise program with mini trampoline and inflatable discs. Before and after the completion of the eight-week balance program, participants completed a single leg static balance assessment for both limbs on the Biodex stability system. Two-way analyses of variance (ANOVAs), with repeated measures on the last factor, were conducted to determine effect of training program groups (traditional, Nintendo Wii) and measures (pre-test, post-test) on balance test indices (SI, API, and MLI). Where initial differences between groups were verified, one-way analyses of covariance (ANCOVAs) were applied. Analysis of the data illustrated that both groups demonstrated an improvement in SI, API and MLI mean scores for the right and the left limp as well. Conclusively, findings support the effectiveness of using the Nintendo Wii gaming console as an intervention for undergraduate Physical Education students, and specifically, its effects on physical function related to balance competence.

Comparing hybrid learning with traditional approaches on learning the Microsoft Office Power Point 2003 program in tertiary education

The purpose of this study was to determine the effectiveness of a hybrid learning approach to deliver a computer science course concerning the Microsoft office PowerPoint 2003 program in comparison to delivering the same course content in the form of traditional lectures. A hundred and seventy-two first year university students were randomly assigned into two teaching method groups: traditional lecture instruction (TLI) and hybrid lecture instruction (HLI). Each group received six 95-min periods of instruction divided into 4 sections: a) 5-min brief outline of the key learning points, b) 40-min lecture on general knowledge c) 45-min constructivist-inspired learning activities and d) 5-min summary on key learning points. In the beginning and the end of this study students completed a 17-item multiple choice knowledge test. Two-way analysis of variances (ANOVA), with repeated measures on the last factor, were conducted to determine effect of method groups (TLI, HLI) and measures (pre-test, post-test) on knowledge test. The measures main effect was significant, as well as the groups x measures interaction effect. Two independent-samples t test were conducted to follow up the significant interaction. Differences in mean ratings of knowledge performance between the two teaching groups were not significantly different at first measure, while the TLI method group yielded a significantly lower mean rating at second measure. The findings indicated that HLI approach might be a superior option for undergraduate students on learning the Microsoft office PowerPoint 2003 program.

Expected and perceived service quality at basketball stadiums in Greece

Abstract The purpose of the current research was to examine the differences between expected quality of service and the perceived quality of service experienced by spectators at selected professional basketball stadiums in Northern Greece. Five hundred spectators filled in the evaluation instrument created for the purpose of the study. The Wilcoxons matched-pairs signed—ranks test showed a statistically significant difference in all 23 items between expectations and perceptions of service quality and in all cases only organizational weaknesses were proved to exist and no strengths. The exploratory factor analysis revealed nine factors: “show time expectations”, “installations evaluation”, “convenience and employee evaluation”, “show time evaluation”, “employee expectations”, “convenience expectations”, “installations expectations”, “comfort evaluation” and “comfort expectations”. The challenge of providing a high quality sport and recreation service becomes less difficult when sport managers know what their customers expect from a service and what they feel is important to quality. From a managerial perspective, identifying the dimensions and knowing both a spectators evaluations and expectations of a provided service indicates the direction that management should take in investing its efforts and resources to increase the probability of the customer experiencing a positive outcome from watching.
