Recently, the relationship between identity and learning has come front and center in discussions about how to design successful
learning environments for youth who struggle in mainstream institutions. In this essay, I explore the role identity development
plays in constructing learning environments for traditionally marginalized youth. While I agree with DeGennaro and Brown on
the importance of identity development for learning, I stretch the relationship between these two constructs in several ways:
First, I will argue that how we define “technology” and what that means for marginalized youth, particularly those who are
assumed to be victims of the “digital divide” is a crucial aspect of the design of successful digital learning environments.
Second, I discuss how identity is represented in these digital learning spaces, and analyze how meaning is constructed in
multimodal spaces such as websites. Finally, I reflect on DeGennaro and Brown’s notion of “emergent design,” as a positive
contribution to design research, and propose the idea of incorporating youths’ already existing competencies into the emergent
design process.

Standard 9 of the National Science Teachers Association Standards for Science Teacher Preparation is designed to ensure that science teacher preparation programs provide preservice science teachers with the knowledge and
skills to understand and successfully engage students in a safe and ethical manner. This standard contains four components
describing science teachers’ legal and ethical responsibilities, appropriate use of instructional materials (chemicals in
particular), emergency procedures and safety equipment, and guidelines for proper use of living organisms in the classroom.
In this article, we describe the requirements of Standard 9 and provide guidance on assessments that can be used to present
evidence for preservice teachers’ competence in each of the four components. 相似文献

The effects of pomegranate extract (PE) supplementation were evaluated on high-intensity exercise performance, blood flow, vessel diameter, oxygen saturation (SPO2), heart rate (HR), and blood pressure (BP). In a randomized, crossover design, nineteen recreationally resistance-trained participants were randomly assigned to PE (1000?mg) or placebo (PL), which were consumed 30?min prior to a repeated sprint ability (RSA) test and repetitions to fatigue (RTF) on bench and leg press. The RSA consisted of ten six-second sprints on a friction-loaded cycle ergometer with 30?s recovery. Brachial artery blood flow and vessel diameter were assessed by ultrasound. Blood flow, vessel diameter, SPO2, HR, and BP were assessed at baseline, 30?min post ingestion, immediately post exercise (IPost), and 30?min post exercise (30minPost). With PE, blood flow significantly increased IPost RSA (mean difference?=?18.49?mL?min?1; P?<?.05), and IPost and 30minPost RTF (P?<?.05) according to confidence intervals (CI). Vessel diameter increased significantly 30minPost RSA according to CI and resulted in a significant interaction IPost and 30minPost RTF (P?<?.05). With PE, according to CI, average and peak power output increased significantly in sprint 5 of the RSA (P?<?.05). There was no significant difference between PE and PL for bench (P?=?.25) or leg press (P?=?.15) repetitions. Acute PE supplementation enhanced vessel diameter and blood flow, suggesting possible exercise performance enhancement from increased delivery of substrates and oxygen. The acute timing and capsule form of PE may be advantageous to athletic populations due to ergogenic effects, taste, and convenience. 相似文献

This article is a critique of the document The Education Industry and The National Competency Agenda, which was produced by members of the Schools and Curriculum Division of the federal Department of Employment, Education and Training (DEET) in April 1992. The authors examine the policy context in which the document was produced. They then go on to analyse the case for reform argued in this document, drawing attention to the mechanisms by which the document seeks to inform and persuade its educational audience. A detailed analysis and critique is made of its central assumptions in relation to teacher education, with a more appropriate agenda for reform of teacher education subsequently outlined. 相似文献
