Smarter,Better, Faster,Cheaper

This article examines and critiques the leadership capacity of department leaders in a high school and attempts to gain a deeper understanding of how department leaders perceive their role as teacher leaders, making a distinction between what an individual department leader does in his or her position and teacher leadership as a form of continuous learning and innovation through collaboration. How do department leaders practice leadership to improve student learning? The author provides an investigation and analysis of the current level of leadership capacity exhibited by department leaders in a high school. A close look at the role and function of department leaders in this high school reveals an absence of the teacher leadership necessary to promote the broad-based leadership capacity that results in improved student achievement.     

Cultural Competence Training for Healthcare Professionals Working with LGBT Older Adults

The population of the aging lesbian, gay, bisexual and transgender (LGBT) community is significant and growing rapidly. As LGBT individuals age and begin to move into healthcare communities, they are fearful of apathy, discrimination, and abuse by healthcare providers and other residents. Person-centered cultural competence and sensitivity among service providers is necessary in order for LGBT individuals to share the same quality of life as other members of the aging community. Programming developed to educate healthcare professionals and aging-services providers on issues related to aging as an LGBT adult must be thoughtfully evaluated to show both efficacy and impact.     

Theories,Concepts, and Techniques: Too Much of a Number of Good Things?

The field of information technology in education is nearly 30 years old. There have been many impressive achievements during that time. However, the field seems to have developed a number of theories, concepts, and activities that are often taken for granted and are regarded as sacrosanct. A case is made for the notion that theories should be practical and that it is possible to have too much of a good thing.     

Design and development research: a model validation case

This is a report of one case of a design and development research study that aimed to validate an overlay instructional design model incorporating the theory of multiple intelligences into instructional systems design. After design and expert review model validation, The Multiple Intelligence (MI) Design Model, used with an Instructional Systems Design (ISD) Model, was tested for use by four practicing instructional designers. Instruction developed for learners using this model was then evaluated measuring post-test and attitudinal scores with 102 participants. This report also provides a reflection on the lessons learned in conducting design and development research on model validation. The procedures and findings have implications for the processes involved in instructional design model validation through designer use and program implementation.

Physical Activity in Former Competitive Athletes: The Physical and Psychological Impact of Musculoskeletal Injury

Although competitive athletes exceed recommendations for physical activity while they are competing in sport, this does not necessarily translate into regular physical activity after retirement from sport. Research suggested the nature of competitive sport participation may not be conducive to lifelong physical activity. We propose one element of competitive sport participation that may impede physical activity post-retirement is injury. We propose that Vela and Denegar’s model of transient disablement in the physically active with musculoskeletal injuries (DPA) may be appropriate to examine the long-term consequences of sport-related injury—particularly with respect to physical activity disablement. Based on our review of literature, we propose the physical and psychological effects of injuries in sports present unique long-term barriers to physical activity in former competitive athletes. Future research could use the DPA as a foundation for assessing the long-term implications of sport-related injuries—particularly with respect to physical activity.     

Whole blood pumping with a microthrottle pump

We have previously reported that microthrottle pumps (MTPs) display the capacity to pump solid phase suspensions such as polystyrene beads which prove challenging to most microfluidic pumps. In this paper we report employing a linear microthrottle pump (LMTP) to pump whole, undiluted, anticoagulated, human venous blood at 200 μl min(-1) with minimal erythrocyte lysis and no observed pump blockage. LMTPs are particularly well suited to particle suspension transport by virtue of their relatively unimpeded internal flow-path. Micropumping of whole blood represents a rigorous real-world test of cell suspension transport given blood's high cell content by volume and erythrocytes' relative fragility. A modification of the standard Drabkin method and its validation to spectrophotometrically quantify low levels of erythrocyte lysis by hemoglobin release is also reported. Erythrocyte lysis rates resulting from transport via LMTP are determined to be below one cell in 500 at a pumping rate of 102 μl min(-1).     

EAST: Developing an electronic assessment and storage tool

Assessment is an ongoing process that evaluates samples of completed student assignments to determine whether the underlying curriculum effectively produces the desired learning outcomes. Each year, the current system of tracking and storing artefacts for assessment becomes increasingly difficult. Compiling the results is a time-consuming process. EAST provides a cohesive web-based solution for managing assessment artefacts. EAST aids the assessment effort through the ability to easily store artefacts in electronic form, support and record the assessment of student work, and ease the development of reports. This paper discusses the analysis, development and features of EAST. The first section discusses the analysis phase of the project, highlighting the system objectives and the requirements of the EAST system. The second section details how the EAST system was developed and implemented. In the last section, features of the system are described and its contribution to the school's assessment effort is discussed.
