Spectrum of Teaching Styles Retrospective 2012

The Spectrum of Teaching Styles was introduced by Dr. Muska Mosston in his 1966 book Teaching Physical Education. In this essay the development of the Spectrum is briefly recounted and five refinements made since 1966 are reviewed. In closing, the authors reflect on the influence of critiques from scholars in the field on the development of the Spectrum and Spectrum research.     

Vision and Optimism: Empowering New Educators

Abstract

When people of faith participate in movements for social change, how are their religious and moral identities formed, challenged, and transformed? Although they have explicit and tangible goals as they participate in advocacy, protest, and boycotts, religious social activists also, James Jasper argues, craft “lives worth living” (1997). This article examines the identity-shaping power of religious participation in social movements, in conversation with scholarship in religious education and social movement theory; describes the relationship between social activism and theological imagination; and proposes some explicit practices for nurturing religious and moral formation.     

Heart Rate Variability

The purpose of the present study was to investigate the influence of two exercise intensities (moderate and severe) on heart rate variability (HRV) response in 16 runners 1 hr prior to (-1 hr) and at +1 hr, +24 hr, +48 hr, and +72 hr following each exercise session. Time domain indexes and a high frequency component showed a significant decrease (p < .001) between -1 hr and +1 hr for severe intensity. The low frequency component in normalized units significantly increased (p <.01) for severe intensity at +1 hr. Only severe exercise elicited a change in HRV outcomes postexercise, resulting in a reduction in the parasympathetic influence on the heart at +1 hr; however, values returned to baseline levels by +24 hr.     

Development and validation of a method to directly measure the cable force during the hammer throw

The development of cable force during hammer-throw turns is crucial to the throw distance. In this paper, we present a method that is capable of measuring cable force in real time and, as it does not interfere with technique, it is capable of providing immediate feedback to coaches and athletes during training. A strain gauge was mounted on the wires of three hammers to measure the tension in the wire and an elite male hammer thrower executed three throws with each hammer. The output from the gauges was recorded by a data logger positioned on the lower back of the thrower. The throws were captured by three high-speed video cameras and the three-dimensional position of the hammer's head was determined by digitizing the images manually. The five best throws were analysed. The force acting on the hammer's head was calculated from Newton's second law of motion and this was compared with the force measured via the strain gauge. Qualitatively the time dependence of the two forces was essentially the same, although the measured force showed more detail in the troughs of the force–time curves. Quantitatively the average difference between the measured and calculated forces over the five throws was 76 N, which corresponds to a difference of 3.8% for a cable force of 2000 N.     

The real ‘cost’ of study in Australia and the ramifications for China,Australia, and the Chinese nursing students: what do these three players want? A narrative review

Australia attracts international nursing students from China to maintain its economic advantage and to alleviate the projected nursing shortage; conversely, China needs its best and brightest citizens who have trained abroad in nursing to return to cope with current challenges within its healthcare system and nursing education. This paper explores whether China can lure its foreign-trained nurses home to achieve its goals; whether China or Australia will win the nursing talent war; and do Chinese nursing students want to remain abroad or return home. The insight gained can support the development of successful human capital investment for all parties involved.     

Phonological and lexical reading in Italian children with dyslexia

In this study we explore the development of phonological and lexical reading in dyslexic children. We tested a group of 14 Italian children who have been diagnosed with dyslexia and whose reading age is end of grade 1. We compared this group with a group of 70 typically developing children who have been tested for reading at the end of grade 1. For each dyslexic child we also selected a participant who was attending the same grade, was close in age, and showed typical reading development when tested with a narrative passage reading task (Cornoldi, Colpo, & Gruppo MT, 1981) for correctness and reading speed. Children in this group are “same grade controls.” We used a reading task consisting of 40 three syllables words. A qualitative and quantitative method of coding children’s naming allowed us to distinguish several components of their reading performance: the grapheme and word recognition, the size of orthographic units involved in the aloud orthography–phonology conversion, the reading process used to recognize words. The comparison of the dyslexic group with the reading age and the same grade control groups reveals different trends of delayed reading processes. Considering dyslexic children’s chronological age, lexical reading is greatly delayed. Considering dyslexic children’s reading age, the type of reading process that is more deeply delayed is phonological reading. The rate of fragmented phonological reading (i.e., a type of syllabized phonological reading) is much higher in dyslexic children compared to the reading age group, suggesting that some factors undermine the possibility of internalizing the orthography–phonology conversion and the blending processes.     

The stability of children's mathematical behavior: When is a bug really a bug?

This article describes an empirical investigation of the extent to which incorrect arithmetic algorithms persist over time. The use of subtraction procedures by children aged 9–11 was charted over time periods of 1–3 months. The ways in which several bugs might be related to a single misconception were considered and a set of “bug classes” was identified. The results indicated that the prevailing tendency to attribute stable procedural knowledge and systematic behavior to children of this age is misguided. They provide some insight into the development of mathematical knowledge under the influence of conventional instruction.     

Impact and dynamics of portfolio assessment and traditional assessment in a college physics course

Popular belief in alternative assessment procedures suggests that the use of student portfolios can help learners successfully organize and integrate newly acquired scientific knowledge. This two-group comparison study documents the use of student created portfolios in an algebra-based, college-level, introductory physics course. Sixteen students were assessed primarily using a portfolio-style assessment procedure. Nineteen students were assessed primarily using traditional, objective examinations. Both groups were given the same cumulative, multiple-choice final examination. All students completed a pre- and post-self-report survey of achievement in physics. There were no significant differences in learner achievement between the two groups on the final examination or on the self-report of achievement given before and after instruction. Analysis of two focus group discussions did, however, suggest that students assessed by portfolios feel less anxious about learning physics, devote considerable time to reading and studying outside of class, internalize and personalize the content material, and enjoy the learning experience. The results of this study suggest that portfolio-style assessment procedures support student achievement at least at the same level as traditional assessment procedures and appear to have additional benefits. © 1997 John Wiley & Sons, Inc.
