Are Educational Psychology Courses Educationally and Psychologically Sound? What Textbooks and Teachers Say     

Kenneth A. Kiewra  Patti S. Gubbels 《Educational Psychology Review》1997,9(2):121-148

Educational psychology courses should be the best taught courses on college campuses given that its instructors and textbook authors are resident experts in learning and teaching. More specifically, we contend that educational psychology courses should adhere to six principles. Educational psychology courses should: (a) be driven by teaching models, (b) integrate theory and practice, (c) provide opportunities to practice teaching skills, (d) present an integrated model for instructional planning, (e) prepare teachers to teach learning strategies, and (f) help students learn. We surveyed practicing teachers and analyzed current educational psychology texts and found that these principles are not upheld. We report on the principles, our findings, and how an educational psychology course that upholds these principles might be developed.  相似文献

The impact of data reduction on the intra-trial reliability of a typical measure of lower limb musculoskeletal stiffness     

Mark P. Moresi  Elizabeth J. Bradshaw  David A. Greene  Geraldine A. Naughton 《Journal of sports sciences》2015,33(2):180-191

Double-leg repeated jumping tasks are commonly used as measures of lower limb stiffness in exercise science research. Within similar stiffness calculations, variation in data-reduction criteria exists. The impact of these varied data-reduction methods on stiffness measures is unknown. Sixteen adolescent female participants from varied physical activity backgrounds performed 15 self-paced, bent-knee continuous jumps (CJb) on two force plates. Leg stiffness was calculated as the ratio of the peak force and the centre of mass displacement for each contact. Using combinations of criteria based on previous literature, 83 data-reduction methods were applied to the raw data. Data reduction suitability was assessed based on intra-trial reliability, the number of participants excluded and the average contacts excluded. Four data-reduction methods were deemed suitable for use with adolescent female populations, with three consecutive contacts within 1 SD of the average jump frequency considered optimal. The average individual stiffness values were not greatly influenced by the data-reduction method; however, for a single participant, a stiffness change of up to 6 kN · m^?1 (30%) was observed. The role and potential impact of data-reduction methods used to evaluate measures of lower limb stiffness during repeated jumping tasks warrants consideration.  相似文献   

Musculoskeletal stiffness during hopping and running does not change following downhill backwards walking     

Corey W. Joseph  Elizabeth J. Bradshaw  Justin Kemp  Ross A. Clark 《Sports biomechanics / International Society of Biomechanics in Sports》2014,13(3):241-258

Eccentric contractions that provide spring energy can also cause muscle damage. The aim of this study was to explore leg and vertical stiffness following muscle damage induced by an eccentric exercise protocol. Twenty active males completed 60 minutes of backward-walking on a treadmill at 0.67 m/s and a gradient of ? 8.5° to induce muscle damage. Tests were performed immediately before; immediately post; and 24, 48, and 168 hours post eccentric exercise. Tests included running at 3.35 m/s and hopping at 2.2 Hz using single- and double-legged actions. Leg and vertical stiffness were measured from kinetic and kinematic data, and electromyography (EMG) of five muscles of the preferred limb were recorded during hopping. Increases in pain scores (over 37%) occurred post-exercise and 24 and 48 hours later (p < 0.001). A 7% decrease in maximal voluntary contraction occurred immediately post-exercise (p = 0.019). Changes in knee kinematics during single-legged hopping were observed 168 hours post (p < 0.05). No significant changes were observed in EMG, creatine kinase activity, leg, or vertical stiffness. Results indicate that knee mechanics may be altered to maintain consistent levels of leg and vertical stiffness when eccentric exercise-induced muscle damage is present in the lower legs.  相似文献   

Muscle dysmorphia, gender role stress, and sociocultural influences: an exploratory study     

Tucker R  Watkins PL  Cardinal BJ 《Research quarterly for exercise and sport》2011,82(2):310-319

Our study explored the contribution of gender role stress (GRS) and sociocultural appearance demands to symptoms of muscle dysmorphia (MD) in a college sample of 219 women and 154 men. For women, five GRS subscales, sociocultural appearance demands, age, and frequency of aerobic exercise predicted MD symptoms (model R2 = .33; F(8,210) = 12.81, p < . 001); for men, only one GRS subscale, age, and sociocultural appearance demands predicted MD symptoms (model R2 = .40; F(3,150) = 9.52, p < .001). Post hoc analyses revealed that a small number of items explained a substantial portion of the variation, suggesting that MD may be more related to specific perceptions of pressure to attain an attractive body than to global gender role stress.  相似文献   

Management training and national sport organization managers: Examining the impact of training on individual and organizational performances     

Patti Millar  Julie Stevens 《Sport Management Review》2012,15(3):288-303

Within sport, a tremendous amount of effort is committed to the on-the-field performance of athletes and coaches, neglecting the off-the-field performance and development of sport managers. This study examines the impact of human resource training on the performance of five Canadian national sport organizations (NSO) and their managers (N = 22). Data were collected on three outcome variables (learning, individual performance, organizational performance) and three mediating variables (motivation to transfer, training design, organizational climate) at three time measures (pretraining, post-training¹, post-training²). Results indicate that training improves the learning and individual performance of sport managers, as well as the organizational performance of NSOs. Varying relationships were found at each of the three time measures, demonstrating that a progression to training-related performance change exists. Implications and future research directions are discussed and highlighted the need for on-going training opportunities for Canadian sport managers.  相似文献   

The role of outdoor recreation in family enrichment     

Patti A. Freeman  Ramon B. Zabriskie 《Journal of Adventure Education & Outdoor Learning》2013,13(2):131-145

Abstract

The family is the fundamental unit in society and perhaps the oldest and most important of all human institutions. Several studies have indicated a positive correlation between strong, successful families and family participation in outdoor recreational activities. This paper addresses the role of structured outdoor recreation programming in family enrichment. Findings from two studies based in the United States are presented: one on the effect of a one-day family outdoor adventure program on parental and child perceptions of family functioning and the other from a qualitative inquiry into the meaning of family residential camping experiences. The first study collected both quantitative and qualitative data from 24 families who participated in an 8-hour outdoor adventure program. The second study utilized structured interviews with 11 families participating in a residential camp experience. Findings from both studies demonstrate that structured outdoor family recreation programming has a strong positive relationship with family strength. Furthermore, findings indicate that the type of outdoor adventure activities being used in the treatment of dysfunctional and maladaptive families is also effective in providing family enrichment experiences.  相似文献   

Diagnosing Teachers’ Understandings of Rational Numbers: Building a Multidimensional Test Within the Diagnostic Classification Framework     

Laine Bradshaw  Andrew Izsák  Jonathan Templin  Erik Jacobson 《Educational Measurement》2014,33(1):2-14

We report a multidimensional test that examines middle grades teachers’ understanding of fraction arithmetic, especially multiplication and division. The test is based on four attributes identified through an analysis of the extensive mathematics education research literature on teachers’ and students’ reasoning in this content area. We administered the test to a national sample of 990 in‐service middle grades teachers and analyzed the item responses using the log‐linear cognitive diagnosis model. We report the diagnostic quality of the test at the item level, mastery classifications for teachers, and attribute relationships. Our results demonstrate that, when a test is grounded in research on cognition and is designed to be multidimensional from the onset, it is possible to use diagnostic classification models to detect distinct patterns of attribute mastery.  相似文献   

A preliminary investigation of an early intervention program: Examining the intervention effectiveness of the Bracken Concept Development Program and the Bracken Basic Concept Scale‐Revised with Head Start students     

Patti Wilson 《Psychology in the schools》2004,41(3):301-311

This research study evaluated the efficacy of the Bracken Basic Concept Scale‐Revised (BBCS‐R; Bracken, 1998) and the Bracken Concept Development Program (BCDP; Bracken, 1986a) in a test‐teach‐test paradigm with students from a Head Start program. Prior to the intervention, 54 children were administered the BBCS‐R and were divided into three groups, two of which received basic concept instruction. Once the intervention was completed, the children were reassessed with the BBCS‐R. Posttest scores were calculated for each BBCS‐R subtest and the Total Test and School Readiness Composites after controlling for the pretest scores. A MANOVA and sequential ANOVAs were conducted and proved a significantly higher performance of the two intervention groups compared to the control group. Effect sizes for five of the six BBCS‐R subtests were classified as large, with the sixth (Time/Sequence) classified as medium. Discriminant function coefficients found that the Texture/Material subtest contributed the most to the detection of differences between the groups. However, no significant difference between the two intervention groups was found. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 301–311, 2004.  相似文献
