A survey of U.S. Atlanta and Nagano Olympians: variables perceived to influence performance

The purpose of this study was to determine the frequency and magnitude of specific variables perceived to have affected U.S. Olympic athlete performance. Participants included 296 Atlanta Olympians and 83 Nagano Olympians. Olympians rated how they perceived specific variables influenced their Olympic performance. Results revealed that numerous variables, including performance influences, such as preparation for distractions and loss of composure; team variables, such as strong cohesion and positive coach-athlete relationships; coaching variables, including coach's ability to deal with crises and coaching expectations; family-friend variables, including general social support and getting event tickets for family and friends; and environmental concerns, such as venue transportation difficulties and Olympic village distractions; were perceived to influence performance. Findings verified the results of qualitative interviews conducted with Olympic athletes and coaches.     

Australian TESOL Teachers’ Cultural Perceptions of Students

Over the last decade, research in the field of Teaching English to Speakers of Other Languages (TESOL) has increasingly focused on the relationship between culture and learning. Researchers such as Kumaravadivelu (2003) have been vocal in their opposition to the practice of cultural stereotyping. In the current study, Holliday’s (2005) model of Culturism was used as a theoretical basis. Six Australian TESOL teachers were interviewed to determine the nature and extent of the cultural stereotypes that they held, particularly as they pertained to specific learning-related behaviours. A qualitative analysis of the data revealed that teachers most often grouped students in terms of national or regional cultures and believed that cultural background strongly influenced student learning behaviour, resulting in the formation of a number of stereotypes. Despite this, the findings also demonstrated that teachers were self-aware of the pitfalls of cultural stereotyping and took other factors influencing student behaviour into consideration.     

Learning to Deflect: Conceptual Change in Physics During Digital Game Play

How does deep conceptual change occur when students play well-designed educational games? To answer this question, we present a case study in the form of a microgenetic analysis of a student’s processes of knowledge construction as he played a conceptually-integrated digital game (SURGE Next) designed to support learning about Newtonian mechanics. Grounded in the Knowledge In Pieces framework of conceptual change (A. diSessa, 1993), we analyze the processes through which the student, Jamal, developed an expert-like understanding of deflections, a phenomenon that has been previously identified as challenging to understand for novice physics learners. We also explore the key characteristics of SURGE Next supporting these conceptual change processes. Our analysis shows that Jamal’s learning involved iterative refinement of his conceptual understanding through distributed encoding (A. diSessa, 1993). That is, as Jamal advanced through the game levels in SURGE Next, he developed a progressively more distributed sense of mechanism (A. diSessa, 1993) and was able to identify and operationalize the roles of the direction and magnitude of an object’s initial (or previous) velocity in determining the velocity resulting from the application of a new impulse. We also discuss the methodological and design implications of our findings for future research on digital games for learning.     

An interactive flow model for projecting school enrolments

Successful planning in educational administration is highly dependent on accurate student numbers. An interactive enrolment projection model is described which begins with pre-school age children to project the expected number of first grade entrants. These cohorts are then progressed through the school system. The model described can be implemented on a microcomputer and uses an interactive technique which enables human intervention in order to take full account of local knowledge in predicting the numbers in each year group. Control is maintained by allowing groups of schools to be amalgamated and then by applying to these larger groups the same techniques used to obtain the initial individual school enrolments. Adjustments to individual school enrolments are then possible following the reconciliation of larger group figures with known demographic statistics. This counteracts the effects of student mobility across wider areas and overcomes many of the problems associated with simple aggregation of individual school projections. The model provides a valuable planning tool when enrolment figures are needed for decision making.     

The effect of attentional focus cues on object control performance in elementary children

Background and purpose: Attentional focus cues have been shown to impact motor performance of adults and children. Specifically, an external focus of attention results in improved motor learning and performance as compared to adopting an internal focus of attention. The purpose of this study was to determine the effects of an internal and external attentional focus cue on children’s object control skill performance during a commonly used motor skill assessment.

Methods: Using a within-participant design, a total of 44 children (M_age?=?7.7 years, 20 boys and 24 girls) completed all three attentional focus conditions. The object control subscale of the Test of Gross Motor Development-2nd Edition (TGMD-2; Ulrich, 2000. Test of Gross Motor Development-2. Austin: Pro-Ed.) served as the motor skill assessment in present study. The TGMD-2 is a normed and criteria-referenced assessment frequently used to assess fundamental motor skill competence in children. The object control subtest of the TGMD-2 assesses a child’s ability to complete six fundamental motor skills – striking a stationary ball, stationary dribble, catch, kick, overhand throw, and underhand roll. All participants completed the object control subtest of the TGMD-2 under three different attentional focus conditions: baseline (i.e. neutral focus), internal, and external. The internal cue focused on movement performance and the external cue focused on movement outcome. In all three conditions, a video demonstration of proper skill performance was used to ensure no difference in visual demonstration, but the overlaying audio was changed to encompass each attentional focus condition. Children’s motor performance was recorded and later coded by a single researcher blinded to the study. A repeated-measures analysis of variance was used to determine if children’s motor scores changed among the three conditions.

Results: Findings demonstrated that children’s performance differed among the three conditions (F_(2,43)?=?3.5, p?Post hoc analysis revealed that children scored significantly better in the external cue condition compared to the baseline (difference?=?1.98, p?Conclusion: Children performed better when given a verbal instruction to focus their attention externally rather than a verbal instruction with no attentional focus cue. No significant differences exist between the internal and external focus condition or between the neutral and internal condition. Our findings align with the literature and support that external attentional focus cues have a positive effect on motor performance. From a teaching and learning standpoint, using consistent instructions appears to be essential for young learners. Slight changes in verbal cues can have a significant effect on how well children execute fundamental motor skills.     

Unusual Sensory Sensitivities in Autism: A possible crossroads

Although there is ample clinical evidence supporting sensory hyper- and hypo-sensitivities in children with autism, empirical evidence is scant. Review of the available evidence indicated that there was a need for further systematic data on unusual sensory-perceptual sensitivities. A questionnaire was developed to investigate this phenomenon in 30 young children with autism and their controls across auditory, tactile, visual, gustatory, and vestibular domains. Significant differences were found between the two groups across all domains, although the limitations of this preliminary investigation need to be taken into account. The findings are interpreted within the framework of theory of mind and joint attention deficit, as well as psychodynamic hypotheses for autism. A brief argument is given as to how an ongoing experience of sensory aberrations may have an inhibitory effect on the prerequisite processes through which social interactivity, attachment, and communication skills develop. The applied implications of the findings are also discussed.     

When Should I Use a Measure to Support Instructional Improvement at Scale? The Importance of Considering Both Intended and Actual Use in Validity Arguments

Despite the ease of accessing a wide range of measures, little attention is given to validity arguments when considering whether to use the measure for a new purpose or in a different context. Making a validity argument has historically focused on the intended interpretation and use. There has been a press to consider both the intended and actual interpretations and how users make sense of the data when constructing validity arguments, but the practice is not widespread. This paper contributes to existing research on validity by highlighting the value of attending to the actual interpretation and use of a measure aimed at supporting instructional improvement in mathematics. We describe the use of the same measure across two contexts to highlight the importance of attending to characteristics of both users and the contexts in which the measures are used when assessing the validity of inferences for the purpose of instructional improvement efforts.     

A bridge between worlds: understanding network structure to understand change strategy

A number of scholars are exploring district and site relations in organizational change efforts in the larger policy context of No Child Left Behind. These studies suggest the importance of the central office as a support to the work of reform and offer strategies for building relations between district offices and sites in order to implement and sustain change efforts. What is frequently overlooked in these studies is that organizational change efforts are often socially constructed. Therefore, examining the underlying social networks may provide insight into structures that support or constrain efforts at change. This exploratory case study uses social network analysis and interviews to examine the communication and knowledge network structures of central office and site leaders in an ‘in need of improvement’ district facing sanctions under No Child Left Behind. Findings indicate sparse ties among and between school site and central office administrators, as well as a centralized network structure that may constrain the exchange of complex information and ultimately inhibit efforts at change.
