Instructional practices of teachers enrolled in educational technology and general education programs

This study investigated classroom practices of 38 teachers enrolled in university masters' degree programs in educational technology and in other areas of education. The classroom practices related to five key concepts associated with educational technology: (a) learner-centered instruction, (b) instructional design, (c) media and technology, (d) assessment, and (e) instructional alignment. Teachers rated their frequency of use of desirable practices in these five areas on a 30-item Likert type survey. In addition, one class of students per teacher rated its own teacher's frequency of use of the practices on 20 items parallel to items on the teacher survey. The mean overall rating across all teachers for the classroom practice items was very close to Often, or 4.0, on the 5-point scale. There were few reported differences between the teachers enrolled in educational technology programs and those enrolled in other education programs. Student ratings indicated less frequent teacher use of the desirable practices on 16 of the 20 common items, with significantly lower student ratings on 8 of these items. However, there was strong teacher-student agreement on several other comparisons.The study reported in this article was conducted as a doctoral dissertation at Arizona State University.

Continuing professional development needs and activities of school psychologists

The study investigated school psychologists' continuing professional development (CPD) needs and their relationship to selected demographic factors, preservice training, incentives, and typical engagement in various CPD activities. A survey questionnaire was mailed to 500 randomly selected National Association of School Psychologists (NASP) members, and responses were received from 235. Respondents reported their greatest CPD needs to be in the areas of direct service and consultation. No demographic variables were related to respondents' CPD needs. Few preservice training or incentive factors were related to CPD needs. Respondents' perceived value of preservice training in CPD management was related to their CPD needs, but few respondents reported that they had received this type of preservice training. Several personal incentives for CPD, including self‐assessment of CPD needs, opportunity to practice new skills and receive feedback during CPD training, and opportunity to evaluate the effectiveness of CPD training and CPD goal attainment were related to CPD needs. Respondents' CPD needs in each specific skill area, including direct service, consultation, assessment, program planning and evaluation, supervision, and research, had significant but low correlations with the amount of actual CPD activity in the respective skill area. © 2001 John Wiley & Sons, Inc.     

Comparison of force-related performance indicators between heavyweight and lightweight rowers

The aim of this study was to examine biomechanical variables relating to the force production of men's Lightweight (LW) and Heavyweight (HW) rowing pairs. Seven HW and seven LW coxless pairs were studied under a range of stroke rates, from 20 spm to race rating (average of 33.7 spm for the HWs and 33.9 spm for the LWs). Each crew was equipped with biomechanical apparatus allowing the measurement of gate force, horizontal oar angle, and boat velocity. The HW crews exhibited significantly higher (p < 0.05) values for all variables examined, at all rates. Peak handle force was 26.2% to 30.2% higher in the HW group. Average handle force ranged from 18.7% to 22.1% higher than the LW group. Work per stroke was found to be 26% to 28% higher for the HW crews, and Power Per Kilogram was also greater for the HW crews, from 24.0% to 29.2%. The LWs were observed to be consistently, but not significantly, slower than the HWs (from 96.9% at the race situation, to 98.7% at 28 spm). These observations are important when considering biomechanical performance indicators in rowing, as significant changes in performance indicators may lead to only minimal alteration in boat velocity.     

Considerations for the use of functional principal components analysis in sports biomechanics: examples from on-water rowing

The proliferation of new biomechanical technology in laboratory and field settings facilitates the capture of data-sets consisting of complex time-series. An understanding of the appropriate statistical approaches for analysing and interpreting these data-sets is required and the functional data analysis (FDA) family of statistical techniques has emerged in the biomechanical literature. Given the use of FDA is currently in its infancy with biomechanical data, this paper will form the first of a two part series aiming to address practical issues surrounding the application of FDA techniques in biomechanics. This work focuses on functional principal components analysis (fPCA), which is explored using existing literature and sample data from an on-water rowing database. In particular methodological considerations for the implementation of fPCA such as temporal normalisation of data, removal of unwanted forms of variation in a data-set and documented methods for preserving the original temporal properties within a set of curves are explored in detail as a part of this review. Limitations and strengths of the technique are outlined and recommendations are provided to encourage the appropriate use of fPCA within the field of applied sports biomechanics.     

How much effort is needed to keep up with the literature relevant for primary care?

OBJECTIVES: Medicine must keep current with the research literature, and keeping current requires continuously updating the clinical knowledge base (i.e., references that provide answers to clinical questions). The authors estimated the volume of medical literature potentially relevant to primary care published in a month and the time required for physicians trained in medical epidemiology to evaluate it for updating a clinical knowledge base. METHODS: We included journals listed in five primary care journal review services (ACP Journal Club, DynaMed, Evidence-Based Practice, Journal Watch, and QuickScan Reviews). Finding little overlap, we added the 2001 "Brandon/Hill Selected List of Print Books and Journals for the Small Medical Library." We counted articles (including letters, editorials, and other commentaries) published in March 2002, using bibliographic software where possible and hand counting when necessary. For journals not published in March 2002, we reviewed the nearest issue. Five primary care physicians independently evaluated fifty randomly selected articles and timed the process. RESULTS: The combined list contained 341 currently active journals with 8,265 articles. Adjusting for publication frequency, we estimate 7,287 articles are published monthly in this set of journals. Physicians trained in epidemiology would take an estimated 627.5 hours per month to evaluate these articles. CONCLUSIONS: To provide practicing clinicians with the best current evidence, more comprehensive and systematic literature surveillance efforts are needed.     

Walter White(ness) lashes out: Breaking Bad and male victimage

This essay situates the television show Breaking Bad (BB) and its critical reception in the context of American politics following the economic and political events of 2008. Reading the show as an allegory, I demonstrate that it offered a pathway for viewers to maintain investments and commitments to a toxic, white masculinity threatened by 2008’s economic and political dislocations. Taking the show up for its capacity to allegorize the human experience, Breaking Bad’s critically acclaimed status among viewers from widely divergent political positions suggests that the investment in raced and gendered ideas of individual freedom crosses partisan lines, indicating that American national identity and white masculinity share a mutually sustaining incoherence. Understanding the cultural roots of American victimage evident in post-2008 America helps explain how BB distinguished itself from similar masculine “anti-hero” dramas.
