Can textured insoles improve ankle proprioception and performance in dancers?

With the aim of determining both the acute and the chronic effects of textured insoles on the ankle discrimination and performance ability of dancers, 60 ballet dancers from the Australian Ballet School, aged 14–19 years, were divided into three groups (two intervention groups and a control group), age- and level-matched. In the first 5 weeks (weeks 1 to 5), the first intervention group (GRP1) was asked to wear textured insoles in their ballet shoes and the second intervention group (GRP2) was not given textured insoles to wear. In the next 5 weeks (weeks 6 to 10), GRP2 was asked to wear the same type of textured insoles and GRP1 did not wear the textured insoles. The control group (CTRL) did not wear textured insoles during the whole 10 weeks. All participants were tested preintervention, after 5 weeks and after 10 weeks for ankle discrimination score (AUC scores). Dance performance was assessed by 5–7 dance teachers. Pre-to-post change in AUC scores was significantly greater for the groups wearing insoles than for the controls (P = .046) and the size of pre-to-post changes did not differ between the two intervention groups (P = .834). Significant correlation was found between ankle discrimination score and performance scores, using the textured insoles (r = .412; P = .024). In conclusion, the stimulation to the proprioceptive system arising from textured insoles worn for five weeks was sufficient to improve the proprioceptive ability and performance ability of ballet dancers.     

Hip and upper extremity kinematics in youth baseball pitchers

The purpose of this study was to examine the relationship between dynamic hip rotational range of motion and upper extremity kinematics during baseball pitching. Thirty-one youth baseball pitchers (10.87 ± 0.92 years; 150.03 ± 5.48 cm; 44.83 ± 8.04 kg) participated. A strong correlation was found between stance hip rotation and scapular upward rotation at maximum shoulder external rotation (r = 0.531, P = 0.002) and at ball release (r = 0.536, P = 0.002). No statistically significant correlations were found between dynamic hip rotational range of motion and passive hip range of motion. Hip range of motion deficits can constrain pelvis rotation and limit energy generation in the lower extremities. Shoulder pathomechanics can then develop as greater responsibility is placed on the shoulder to generate the energy lost from the proximal segments, increasing risk of upper extremity injury. Additionally, it appears that passive seated measurements of hip range of motion may not accurately reflect the dynamic range of motion of the hips through the progression of the pitch cycle.     

Developing networks of grass-roots science curriculum action

This paper describes an ongoing process of participatory curriculum development. It outlines some of the tensions which need to be explored in science curriculum development: debates about the nature of science, of society, of school science content and of learning theories. The process whereby action can arise from this debate is also explored. An example will be outlined of a network of science curriculum action which has developed from the work of a range of science education projects in Natal, South Africa. Specializations: science curriculum development from primary to tertiary level. Specializations: inservice primary science teacher development. Specializations: inservice teacher development, biology education. Specializations: environmental education, teacher development. Specializations: environmental education, teacher development.

Relations of Children's Effortful Control and Teacher-Child Relationship Quality to School Attitudes in a Low-Income Sample

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children.     

Teacher Efficacy Research 1998–2009: Signs of Progress or Unfulfilled Promise?

This review investigates the state of teacher self- and collective efficacy research conducted from 1998 to 2009. Two hundred and eighteen empirical articles published in 1998–2009 were examined for key characteristics and compared to research published in the previous 12 years (i.e., 1986–1997). Results from the review show increases in overall teacher efficacy research, methodological diversity, domain specificity, internationalization, and focus on collective efficacy. Continuing problem areas were a lack of attention to the sources of teacher efficacy, continued measurement and conceptual problems, a lack of evidence for the links between teacher efficacy and student outcomes, and uncertain relevance of teacher efficacy research to educational practice. An outline of directions for future teacher efficacy research is provided.     

Engendering habits of mind and heart through integrative learning

Students are often exposed to an almost breathtaking array of curricular and cocurricular learning experiences, but how do we help them make meaning of their diverse learning? Simone Himbeault Taylor suggests pedagogical processes that promote reflection across learning experiences in a student‐centered approach to integrate learning.     

Students’ perceptions of classroom instructional environments in the context of ‘Universal Design for Learning’

Using a sample of 867 students in Grades 5–12, the present study investigated whether students’ perceptions toward the instructional environment in classrooms that employed Universal Design for Learning differed by school grade level and teacher gender. High-school students in the study showed higher perception scores than upper-elementary or middle-school students in the personalisation and participation aspect of the classroom environment. The results for teacher gender indicated that students in the study perceived a more personalised classroom environment with female teachers than with male teachers. Policy implications and methodological considerations are provided for future study.
