Designing System Dualities: Characterizing a Web-Supported Professional Development Community

In this article we focus on the challenges we have encountered in attempting to support the development of an online community of practice for grade 5-12 mathematics and science teachers. Specifically, this project involves the design and evaluation of an electronic knowledge network, the Inquiry Learning Forum (ILF), a web-based professional development system designed to support a community of practice (CoP) of in-service and preservice mathematics and science teachers who are creating, reflecting upon, sharing, and improving inquiry-based pedagogical practices. This research examines the interplay among a variety of variables that characterize the dynamics of building a social network through which participating teachers will seek to share and improve their pedagogical practices. Our research suggests that designing for virtual communities involves balancing and leveraging complex dualities from the "inside" rather than applying some set of design principles from the "outside." This research provides an illuminative case study from which others can more readily identify patterns occurring in their own interventions and navigate the challenges they face more intelligently.     

Lower-body compression garments worn following exercise improves perceived recovery but not subsequent performance in basketball athletes

ABSTRACT

This study examined the effects of lower-body compression garments on perceived recovery and subsequent performance in basketball athletes. In a parallel-group design, 30 recreational, male basketball athletes were randomly allocated to either a control (CON, n = 15, loose-fitting clothing) or experimental group (COMP, n = 15, compression garments) for 15 h following fatigue-inducing, basketball-specific exercise in the evening (1600-1800 h). Perceptual measures of fatigue and muscle soreness, as well as physical performance tests (sprints, jumps and agility), were performed pre-exercise, post-exercise, and post-recovery (15 h following exercise). Subjective and objective measures of sleep were recorded following the exercise trial. There were non-significant (p > 0.05), unclear-trivial differences between groups for all performance measures. Perceived post-recovery fatigue (d = ?1.27, large) and muscle soreness (d = ?1.61, large) were significantly lower in COMP compared to CON (p < 0.05). COMP exhibited better perceived sleep quality (d = 0.42, small, p = 0.18) than CON, with an unclear difference in sleep duration between groups (p > 0.05). Wearing lower-body compression garments overnight improved perceived fatigue and muscle soreness, but had negligible effects on subsequent physical performance in basketball athletes. Future research should focus on longer periods of compression wear following fatiguing exercise.     

Chicken Club: schools and their relationship with families

Over time, schools have developed systems that include the families of children. Families often sign a home school agreement and attend parent forums or more formal meetings designed to plan provision for children with special educational needs. These endeavours, however, are arguably inadequate when the full influence of the family is properly acknowledged. Research makes clear that the main influencer on the child’s self-efficacy and therefore learning behaviours, is the family. This article reports findings from literature and a case study looking at making the most of the partnership between families and schools in order to meet the learning needs of individual children. It also addresses many barriers that families face in approaching schools and three ways schools in Cornwall, a rural county in South West England, are 'opening out’ their practice. The case study provides evidence of the progress children made in learning as a response to the new school and family partnership.     

Military Sexual Trauma: Considerations for Social Work Education

ABSTRACT

Military sexual trauma (MST) is an experience unique to veterans, and it is essential that social workers receive military-specific education in preparing for work with this population. This article discusses the impact of MST on veterans, cultural considerations for social workers working with this population, and the Veterans Administration’s efforts to address MST. In addition, the need to emphasize the utilization of evidence-based practice in social work education and the importance of incorporating military specific curricula material is discussed.     

Teachers’ perceptions, attitudes and beliefs regarding curriculum integration

This paper summarises the results of a three-day workshop conducted between October and December of 2007 as part of a larger project dedicated to improving teacher quality at the pre-service and in-service levels. Both pre- and post-test measures were administered before and after workshop completion in order to capture changes in knowledge, attitude, and perception. For contextual relevance, findings are summarised in light of extant literature pertaining to curriculum integration.     

“I Never Thought I Would Read This Much”: Becoming a Reader

The purpose of this qualitative study was to describe the reading volume and book choices of fourth-grade students and how they identified as readers. Students were encouraged to read 50 books independently. The results showed that students read throughout the year. Grade-level readers described themselves as being a part of the book, while above- and below-grade-level readers identified by their rate of reading. All students increased in reading achievement as measured through assessments.     

Systems learning with a conceptual representation: a quasi-experimental study

In this paper, we share results from a classroom intervention that used a conceptual representation to support reasoning about ecosystems. Engaging students in modeling allows them to make their ideas visible while being malleable and available for discussion, which enables students to make meaning out of systems. Further, the Components-Mechanisms-Phenomena (CMP) conceptual representation was designed to enable students to construct coherent mental models. Following our intervention, students deepened their understanding of ecosystem dynamics when compared to students who engaged in traditional instruction without use of the CMP conceptual representation. We discuss our results in terms of data that helped guide the design of the intervention and we describe a theoretical perspective that can be used to guide future instruction.     

Design and Reflection Help Students Develop Scientific Abilities: Learning in Introductory Physics Laboratories

Design activities, when embedded in an inquiry cycle and appropriately scaffolded and supplemented with reflection, can promote the development of the habits of mind (scientific abilities) that are an important part of scientific practice. Through the Investigative Science Learning Environment (ISLE), students construct physics knowledge by engaging in inquiry cycles that replicate the approach used by physicists to construct knowledge. A significant portion of student learning occurs in ISLE instructional labs where students design their own experiments. The labs provide an environment for cognitive apprenticeship enhanced by formative assessment. As a result, students develop interpretive knowing that helps them approach new problems as scientists. This article describes a classroom study in which the students in the ISLE design lab performed equally well on traditional exams as ISLE students who did not engage in design activities. However, the design group significantly outperformed the non-design group while working on novel experimental tasks (in physics and biology), demonstrating the application of scientific abilities to an inquiry task in a novel content domain. This research shows that a learning environment that integrates cognitive apprenticeship and formative assessment in a series of conceptual design tasks provides a rich context for helping students build scientific habits of mind.
