A lower extremity strength-based profile of NCAA Division I women’s basketball and gymnastics athletes: implications for knee joint injury risk assessment

This study aimed to provide a comprehensive strength-based physiological profile of women’s NCAA Division I basketball and gymnastic athletes; and to make sport-specific comparisons for various strength characteristics of the knee flexor and extensor muscles. A focus on antagonist muscle balance (hamstrings-to-quadriceps ratios, H:Q) was used to elucidate vulnerabilities in these at-risk female athletes. Fourteen NCAA Division I women’s basketball and 13 gymnastics athletes performed strength testing of the knee extensors and flexors. Outcome measures included absolute and relative (body mass normalised) peak torque (PT), rate of torque development at 50, 100, 200 ms (RTD50 etc.) and H:Q ratios of all variables. The basketball athletes had greater absolute strength for all variables except for isokinetic PT at 240°s^?1 and isometric RTD50 for the knee extensors. Gymnasts showed ~20% weaker body mass relative concentric PT for the knee flexors at 60 and 120°·s^?1, and decreased conventional H:Q ratios at 60 and 240°·s^?1 (~15%). These findings suggest that collegiate level gymnastics athletes may be prone to increased ACL injury risk due to deficient knee flexor strength and H:Q strength imbalance. Coaches may use these findings when implementing injury prevention screening and/or for individualised strength training programming centered around an athletes strength-related deficits.

Information Literacy Advocates: developing student skills through a peer support approach

Since 2013/2014, an Information Literacy Advocates (ILA) scheme has been running at the University of Nottingham as an extracurricular module on the Nottingham Advantage Award programme. The Information Literacy Advocates scheme, which recruits medicine and health sciences students in their second year or above, aims to facilitate development of information literacy skills and confidence, as well as communication, organisation and teamwork, through the provision of peer support. Previous research indicates peer assistance effectively enhances such skills and is valued by fellow students who welcome the opportunity to approach more experienced students for help. This article, written by guest writer Ruth Curtis from the University of Nottingham, provides an overview of administering the ILA scheme and explores its impact on the Information Literacy Advocates, peers and librarians, and discusses future developments for taking the scheme forward.

Age of Entry to Kindergarten and Children's Academic Achievement and Socioemotional Development

Research Findings: Data on more than 900 children participating in the National Institute of Child Health and Human Development Study of Early Child Care were analyzed to examine the effect of age of entry to kindergarten on children's functioning in early elementary school. Children's academic achievement and socioemotional development were measured repeatedly from the age of 54 months through 3rd grade. With family background factors and experience in child care in the first 54 months of life controlled, hierarchical linear modeling (growth curve) analysis revealed that children who entered kindergarten at younger ages had higher (estimated) scores in kindergarten on the Woodcock—Johnson (W-J) Letter-Word Recognition subtest but received lower ratings from kindergarten teachers on Language and Literacy and Mathematical Thinking scales. Furthermore, children who entered kindergarten at older ages evinced greater increases over time on 4 W-J subtests (i.e., Letter-Word Recognition, Applied Problems, Memory for Sentences, Picture Vocabulary) and outperformed children who started kindergarten at younger ages on 2 W-J subtests in 3rd grade (i.e., Applied Problems, Picture Vocabulary). Age of entry proved unrelated to socioemotional functioning.

Practice: The fact that age-of-entry effects were small in magnitude and dwarfed by other aspects of children's family and child care experiences suggests that age at starting school should not be regarded as a major determinant of children's school achievement, but that it may merit consideration in context with other probably more important factors (e.g., child's behavior and abilities).     

The tensions of transformation in three cross-institutional wikibook projects

Wikis have the potential to change learning environments from traditional knowledge transmission models to knowledge transformative ones where students generate, share, and reshape knowledge. In this three-part study, graduate students created wikibooks across institutional settings. One of these projects extended to universities in China, Taiwan, Malaysia, and the United States, whereas the other two involved two universities in the United States. The degree of scaffolding and other support varied in each project. At the end of each study, students were surveyed about their wikibook efforts. In addition, instructors across the institutions were interviewed about the obstacles they faced as well the opportunities. Based on these results, more than two dozen cross-institutional wikibook issues are organized into five key themes: (1) instructional issues; (2) collaboration issues; (3) technology issues; (4) constructivism and sense of community issues; and (5) wikibook issues. Several recommendations are offered related to the use of wikibooks in the classroom as a transformational learning tool.     

An Evaluation of the Promoting Alternative Thinking Strategies Curriculum at Key Stage 1

Promoting Alternative Thinking Strategies (PATHS) is a curriculum designed to promote social and emotional thinking in primary aged pupils. Research in the US has indicated that where used there has been an increase in emotional understanding and a decrease in behavioural difficulties. This study relates to 287 children (114 from intervention schools and 173 controls). Pre‐ and post‐assessment using the strengths and difficulties questionnaire (SDQ) indicated a significant improvement on all five dimensions for the intervention group but not the control. Teacher interviews also indicated that they perceived the programme to have helped children acquire a better understanding of emotions and to have fostered better empathy and self‐control skills.
