Mechanics of Batting: Effect of Stride Technique on Ground Reaction Forces and Bat Velocities

The benefits associated with being physically active are well documented, but a significant proportion of the population is insufficiently active. Physical inactivity is a major health risk factor in our society, and physical education programs are consistently identified as a means to address this concern. The purpose of this article is to use the social-ecological model as a framework to examine ways in which physical education programs can play an important role in promoting physical activity. Policies that require time allocations and resources for physical education and physical activity in schools and community designs that provide infrastructure that makes being physically active accessible and convenient are important factors in making schools and communities healthier spaces. It is clear, however, that policies alone are not sufficient to address concerns about physical inactivity. We must consider individual factors that influence decisions to be physically active in efforts to engage children in physical education programs that promote active lifestyles. The learning climate that teachers create determines what students do and learn in physical education classes. Ensuring that students see value in the content presented and structuring classes so that students believe they can experience success when they exert effort are key elements in an effective motivational climate. Efforts to address public health concerns about physical inactivity require a comprehensive approach including quality physical education. It is critical that kinesiology professionals emerge as leaders in these efforts to place physical education programs at the center of promoting children's physical activity.     

Waist Circumference,Pedometer Placement,and Step-Counting Accuracy in Youth

This study examined whether differences in waist circumference (WC) and pedometer placement (anterior vs. midaxillary vs. posterior) affect the agreement between pedometer and observed steps during treadmill and self-paced walking. Participants included 19 pairs of youth (9–15 years old) who were matched for sex, race, and height and stratified by WC (high WC: HWC; low WC: LWC). Participants performed 3-min treadmill-walking trials at speeds of 59, 72, and 86 m·min-1 and a 400-m self-paced walking trial on level ground. Bland-Altman plots were used to assess the agreement between pedometer and observed steps of spring-levered pedometers by WC, pedometer placement, and walking speed. In the HWC group, the posterior pedometer placement consistently agreed most closely with observed steps at all treadmill speeds and during self-paced walking. In the LWC group, no single pedometer placement consistently agreed most closely with observed steps at all treadmill speeds and during self-paced walking. We conclude that a posterior pedometer placement improves step-count accuracy in most youth with an HWC at a range of walking speeds on level ground.     

Motor and coordination difficulties in children with emotional and behavioural difficulties

To date, very few studies have explored the incidence of motor impairment amongst children with social, emotional and behavioural difficulties (social, emotional and mental health (SEMH); formerly SEBD in England). Following research that suggests an increase in motor difficulties in young children and adolescents with SEMH difficulties, this study compares profiles of motor ability using the Movement ABC-2 assessment in children attending a specialist SEMH primary school with a typically developing comparison group and children with a diagnosis of developmental coordination disorder. We report an increased prevalence of borderline or clinically significant motor impairment amongst children with SEMH difficulties compared to the comparison group, with 44% of the SEMH special school sample falling within these ranges. We suggest that bearing in mind the increased likelihood for motor impairment is important in SEMH education, as it has likely impact on classroom functioning and ability and motivation to take part in socially and academically relevant activities.     

Towards numeracy for the third millennium: A study of the future of mathematics and mathematics education

The research reported here has sought to identify target skills and abilities that will compose a future numeracy, so that new expertise can be incorporated and the exposed deficiencies remedied within a dynamic rather than static concept of competency. A nation-wide selection of panellists contributed to a three-round Delphi process, with the final data comprising both structured responses and qualitative comment. The scope of the items covered calculating activities, writing activities, reading activities, physical skills, supporting (mental) skills, applications, and problem solving. Responses to the structured items have provided priorities for numeracy for the turn of the century, in terms of both expected and desired characteristics. In general, expectations for numeracy fall short of the levels deemed desirable by panel consensus. The qualitative comments have been incorporated into three scenarios reflecting altermative visions for the future. A comparison of the scenarios uncovers wide differences between informed thinkers with respect to future visions of the ends, means, and mechanics of learning. These differences among individuals who are otherwise consistent in their views of future needs must be addressed if the identified priorities are not to be lost in a quagmire of conflicting interests, opinions, priorities, and values.     

An Examination of the Relationship between Computation,Problem Solving,and Reading

The purpose of this study is to evaluate the relationship of mathematics calculation rate (curriculum-based measurement of mathematics; CBM-M), reading rate (curriculum-based measurement of reading; CBM-R), and mathematics application and problem solving skills (mathematics screener) among students at four levels of proficiency on a statewide test. It was hypothesized that CBM-M provides insufficient information to make good screening decisions and that other measures with content more similar to that of large-scale tests of mathematics would function to improve screening. One hundred and seventy students in third grade from a rural elementary school in the Midwestern United States participated. Structural equation modeling was used to evaluate direct, mediator, and latent growth models. In general, CBM-R mediated the relationship between the mathematics ability screener and passing the state assessment, while CBM-M did not have any significant paths within these models. Results are discussed in terms of the utility of CBM-M and CBM-R procedures in screening for success on state test performance in mathematics.     

The Relation between Individual Differences in Fantasy and Theory of Mind

The relation between early fantasy/pretense and children's knowledge about mental life was examined in a study of 152 3- and 4-year-old boys and girls. Children were interviewed about their fantasy lives (e.g., imaginary companions, impersonation of imagined characters) and were given tasks assessing their level of pretend play and verbal intelligence. In a second session 1 week later, children were given a series of theory of mind tasks, including measures of appearance-reality, false belief, representational change, and perspective taking. The theory of mind tasks were significantly intercorrelated with the effects of verbal intelligence and age statistically controlled. Individual differences in fantasy/pretense were assessed by (1) identifying children who created imaginary characters, and (2) extracting factor scores from a combination of interview and behavioral measures. Each of these fantasy assessments was significantly related to the theory of mind performance of the 4-year-old children, independent of verbal intelligence.     

Anatomical Sciences Education Vol. 5, Issue 3, 2012 Cover Image

Medical students at the Schulich School of Medicine and Dentistry at The University of Western Ontario in London, Ontario, Canada, learn clinical facts about the hepatobiliary system as transplant surgeon Dr. Vivian McAlister (at the far right) demonstrates Whipple's procedure in the anatomy laboratory. In this issue of ASE, Ullah and colleagues describe an extracurricular student initiative known as the Surgically Oriented Anatomy Program (SOAP), which aims to deliver anatomy teaching from a surgical perspective through the philosophy of “education through recreation”.     

Learning surgically oriented anatomy in a student-run extracurricular club: an education through recreation initiative

Didactic and laboratory anatomical education have seen significant reductions in the medical school curriculum due, in part, to the current shift from basic science to more clinically based teaching in North American medical schools. In order to increase medical student exposure to anatomy, with clinical applicability, a student-run initiative called surgically oriented anatomy prosectors (SOAP) club was created within the extracurricular program at the Schulich School of Medicine and Dentistry, The University of Western Ontario, London, Canada. SOAP invites surgeons and residents from various surgical specialties to demonstrate, on a cadaver, a surgical procedure of their choosing. During the demonstration, the anatomy, as it relates to the surgical procedure, is discussed. The students then break into smaller groups to examine the relevant anatomy on the cadavers, during which time the discussion is broadened. The group continues the conversation in a social environment with refreshments. SOAP is one of the most popular extracurricular clubs with 65% of first and second year medical students registered as members. The high demand for SOAP, along with the positive participant feedback, may be due to its utilization of the principle of education through recreation, which seeks to provide opportunities for learning seamlessly throughout all facets of life. It also demonstrates the desire, amongst certain medical students, to learn applied anatomy, particularly within a surgical context.     

Students Abroad Studying Their Own Thing

Abstract

This paper defines teacher empathy, argues that teacher empathy enhances student learning, and offers suggestions for increasing teacher empathy. Teacher empathy is the degree to which an instructor works to deeply understand students’ personal and social situations, to feel care and concern in response to students’ positive and negative emotions, and to respond compassionately without losing the focus on student learning. Teacher empathy is communicated to students through course policies as well as the instructor’s behavior toward students. To increase teacher empathy, we review non-pejorative explanations for undesirable student behavior (e.g., fear of failure), and we suggest ways in which faculty can learn about their students and can structure course policies to increase teacher empathy. Ultimately, we call for research on teacher empathy and student learning.
