Does Thoughtfully Adaptive Teaching Actually Exist? A Challenge to Teacher Educators     

James V. Hoffman  Gerald G. Duffy 《理论付诸实践》2016,55(3):172-179

In this article, we explore the roots of thoughtfully adaptive teaching in reflection. Drawing on the conceptual work of Dewey and Schon, we examine reflective practice in teaching as a tool for resistance against institutional pressures to standardize teaching practices. We describe 2 programs of research related to this topic. One program of research is focused on teacher adaptations to practice in the classroom. The second program of research is focused on coaching teachers to develop strategies for thoughtfully adaptive teaching. We draw on the work of Janks around deconstruction and reconstruction for critical teaching practices.  相似文献

School‐based health promotion: An introduction to the practitioner's edition

In this age of increasing professional accountability, it is important that school practitioners engage in evidence‐based practices. In support of this goal, the intent of this special issue is to disseminate practical, user‐friendly, evidenced‐based information related to school‐based health issues. This article introduces the Psychology in the Schools “Practitioner's Edition” on school‐based health promotion. A conceptual framework for the issue, encompassing universal prevention strategies and tertiary intervention strategies, is described. First, school practitioners have unique opportunities to promote healthy behavior for all children and to engage in universal prevention of common health conditions. Second, practitioners should recognize the special needs of children with specific diagnosed medical conditions and employ individualized intervention strategies for these children. © 2007 Wiley Periodicals, Inc.  相似文献   

The influence of self-efficacy and metacognitive prompting on math problem-solving efficiency     

Bobby Hoffman  Alexandru Spatariu   《Contemporary educational psychology》2008,33(4):875-893

A regression design was used to test the unique and interactive effects of self-efficacy beliefs and metacognitive prompting on solving mental multiplication problems while controlling for mathematical background knowledge and problem complexity. Problem-solving accuracy, response time, and efficiency (i.e. the ratio of problems solved correctly to time) were measured. Students completed a mathematical background inventory and then assessed their self-efficacy for mental multiplication accuracy. Before solving a series of multiplication problems, participants were randomly assigned to either a prompting or control group. We tested the motivational efficiency hypothesis, which predicted that motivational beliefs, such as self-efficacy and attributions to metacognitive strategy use are related to more efficient problem solving. Findings suggested that self-efficacy and metacognitive prompting increased problem-solving performance and efficiency separately through activation of reflection and strategy knowledge. Educational implications and future research are suggested.  相似文献

Accuracy and Prediction in Throwing: A Taxonomic Analysis of Children's Performance     

Shirl J. Hoffman  Charles H. Imwold  John A. Koller 《Research quarterly for exercise and sport》2013,84(1):33-40

Abstract

The throwing and prediction performances of first, third and fifth grade boys and girls were analyzed within the framework of a four-part taxonomy originally conceived by Fitts (1965). Throwing performance was assessed under task conditions which varied the motion states of the thrower's body and the target (stationary or moving) by use of a dual pendulum apparatus. Accuracy scores were highest in a condition where both body and target were stationary, and lowest where both body and target were moving. Task conditions requiring motion of only target or of body were of intermediate difficulty, and scores for these tasks were not significantly different from each other. There was evidence of learning across trial blocks for all tasks, but no indication that rates of acquisition differed for the task types. Likewise, significant main effects were observed for age levels but no age X task type interactions were disclosed. Boys were more accurate than girls across task conditions, most noticeably on the two most difficult tasks. Comparison of subjects' ability to predict, from a stationary body position, the coincidence of the moving target with a standard reference point, and their ability to predict the coincidence of their moving body with the same reference point revealed lower error scores on the former prediction task.  相似文献

The Meaning of Work/Life: A Corporate Ideology of Work/Life Balance     

Mary F. Hoffman  Renee L. Cowan 《Communication quarterly》2013,61(3):227-246

Organizations wield great power over the structure of contemporary life. Using the rhetorical method of cluster analysis, we investigated the construction of work/life issues on Web sites of companies on Fortune's 2004 list of “100 Best Companies to Work for.” By identifying key terms and the terms that clustered around them, we uncovered a corporate ideology of work/life: 1) work is the most important element of life; 2) life means family; 3) individuals are responsible for balance; and 4) organizations control work/life programs. We conclude that organizational work/life programs may increase, rather than decrease, the amount of control organizations exercise over personal life. We explore the implications of this finding as well as directions for future research.  相似文献   

Urine dipstick analysis for identification of runners susceptible to acute kidney injury following an ultramarathon   总被引：1，自引：0，他引：1

Abstract

This study examined whether urine dipstick testing might be useful to predict the development of acute kidney injury after an ultramarathon. Participants in the 2011 161-km Western States Endurance Run underwent post-race blood and urine dipstick analyses. Of the 310 race finishers, post-race urine dipstick testing was completed on 152 (49%) and post-race blood also was obtained from 150 of those runners. Based on “injury” and “risk” criteria for acute kidney injury of blood creatinine 2.0 and 1.5 times estimated baseline, respectively, 4% met the criteria for injury and an additional 29–30% met the criteria for risk of injury. Those meeting the injury criteria had higher creatine kinase concentrations (P < 0.001) than those not meeting the criteria. Urine dipstick tests that read positive for at least 1+ protein, 3+ blood, and specific gravity ≥ 1.025 predicted those meeting the injury criteria with sensitivity of 1.00 (95% confidence interval [CI] 0.54–1.00), specificity of 0.76 (95% CI 0.69–0.83), positive predictive value of 0.15 (95% CI 0.06–0.30), negative predictive value of 1.00 (95% CI 0.97–1.00), and likelihood ratio for a positive test of 4.2. We conclude that urine dipstick testing was successfully able to identify those individuals meeting injury criteria for acute kidney injury with excellent sensitivity and specificity.  相似文献   

A biomechanical comparison of dominant and non-dominant limbs during a side-step cutting task     

Christine D. Pollard  Marc F. Norcross  Sam T. Johnson  Amanda E. Stone  Eunwook Chang  Mark A. Hoffman 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(2):271-279

Abstract

Numerous studies have investigated anterior cruciate ligament (ACL) injury risk by examining gender differences in knee and hip biomechanics during a side-step cutting manoeuvre since it is known that ACL injury often occurs during such a task. Recent investigations have also examined lower extremity (LE) biomechanics during side-step cutting in individuals following ACL reconstruction (ACLR). Common research practice is to compare knee and hip biomechanics of the dominant limb between groups but this can add considerable complexity for clinicians and researchers. At this time, it is not known if there is a difference in LE biomechanics between the dominant and non-dominant limb during side-step cutting. Three-dimensional kinematics and kinetics were collected while 31 healthy participants performed five, side-step cutting manoeuvres with the dominant and non-dominant limbs. Knee and hip variables examined are those commonly investigated in ACL injury literature. There were no differences between limbs in all but one variable (knee internal rotation). These results demonstrate that healthy individuals exhibit little side-to-side differences in certain LE biomechanics when performing a side-step cutting manoeuvre. These findings can be utilised by clinicians when conducting dynamic evaluations of their ACLR patients and when developing injury prevention and rehabilitation programmes.  相似文献
