Communication in performance‐based training and instruction: From design to practice

Communication is inextricably important to instructional design and performance‐based training. Promoting effective communication as an integral part of the performance support system improves professional instructional design functions and offers greater avenues for meaningful discourse among end users of the instruction. In this article, we highlight communication in performance training and instruction for meaningful learning and effective exchange of knowledge. Internal and external communications are discussed as a means to promoting successful relationships, commitment, and ownership.     

"Anatomizing" reversed: Use of examination questions that foster use of higher order learning skills by students

"Anatomizing" is a new verb some use to describe the breaking apart of a complex entity such as the human body, into isolated tidbits of information for study, which can never equal the complex, integrated whole. Although popular with first-year medical students, this practice of "tidbitting" anatomical information into easy to memorize facts or tables of facts does not prepare medical students for the inevitable task of dealing with the integrated structure-function of the human body, both normal and diseased, as patient managers. Examination questions drive the cognitive methods students will use to learn content. Asking students on examinations for recall of previously memorized tidbits fosters the cognitive learning behavior of only memorization. Examination questions, however, can be constructed that assess student understanding and integration of the content, that is, student use of cognitive and metacognitive methods of higher order learning that will foster high-quality learning producing better practitioners and lifelong learners. This kind of efficient student learning needs to begin in the first year of medical school.Learning more efficiently and at deeper levels of understanding is especially pertinent as the contact hours in anatomy courses continue to decrease.     

Accuracy and precision of loadsol® insole force-sensors for the quantification of ground reaction force-based biomechanical running parameters

Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for measuring in the field are needed. This work analysed the accuracy and precision of a new wireless insole forcesensor for quantifying running-related kinetic parameters. Vertical ground reaction force (GRF) was simultaneously measured with pit-mounted force plates (1?kHz) and loadsol^® sensors (100?Hz) under unshod forefoot and rearfoot running-step conditions. GRF data collections were repeated four times, each separated by 30 min treadmill running, to test influence of extended use. A repeated-measures ANOVA was used to identify differences between measurement devices. Additionally, mean bias and Bland–Altman limits of agreement (LoA) were calculated. We found a significant difference (p?® devices for these parameters. For these same parameters, the LoA analysis showed that 95% of all measurement differences between insole and force plate measurements were less than 12%, demonstrating high precision of the sensors. However, highly dynamic behaviour of GRF, such as force rate, is not yet sufficiently resolved by the insole devices, which is likely explained by the low sampling rate.     

A single session of treadmill running has no effect on plasma total ghrelin concentrations

Abstract

Ghrelin is a hormone that stimulates hunger. Intense exercise has been shown to temporarily suppress hunger after exercise. In the present study, we investigated whether post-exercise hunger suppression is mediated by reduced plasma total ghrelin concentrations. Nine men and nine women participated in the study. Their mean physical characteristics were as follows: age 24.8 (s _x  = 0.9) years, body mass index 22.9 (s _x  = 0.6) kg · m^?2, maximal oxygen uptake ([Vdot]O_2max) 57.7 (s _x  = 2.2) ml · kg^?1 · min^?1. The participants completed two 3-h trials (exercise and control) on separate days in a randomized balanced design after overnight fasts. The exercise trial involved a 1-h treadmill run at 73.5% of [Vdot]O_2max followed by 2 h of rest. The control trial consisted of 3 h of rest. Blood samples were collected at 0, 0.5, 1, 1.5, 2, and 3 h. Total ghrelin concentrations were determined from plasma. Hunger was assessed following blood sampling using a 15-point scale. The data were analysed using repeated-measures analysis of variance. Hunger scores were lower in the exercise trial than in the control trial (trial, P = 0.009; time, P < 0.001; trial × time, P < 0.001). Plasma total ghrelin concentrations did not differ between trials. These findings indicate that treadmill running suppresses hunger but this effect is not mediated by changes in plasma total ghrelin concentration.     

Benefits of assistive reading software for students with attention disorders

This study investigated how assistive reading software affected the reading performance of a group of 20 post-secondary students who had a primary diagnosis of attention disorder. These students used assistive reading software for most of a semester to read assignments for an English class and in testing sessions in which comparisons were made between normal, unassisted reading, and reading assisted by the soft ware. This software provides a synchronized visual and auditory presentation of text, and incorporates study skills tools for highlighting and note taking. Attention measures, reading speed, comprehension scores, and attitude questionnaire responses were obtained during these sessions. The principal findings were that the assistive software allowed the students to attend better to their reading, to reduce their distractibility, to read with less stress and fatigue, and to read for longer periods of time. It helped them to read faster and, thereby, to complete reading assignments in less time. It did not have a significant effect on comprehension, but it helped some students whose comprehension was very poor. The study results indicate that assistive reading software should be considered as a significant intervention to assist students who have attention disorders and as an accommodation to help them compensate for their disabilities.     

EMPIRICAL SYNTHESIS OF THE EFFECT OF STANDARD ERROR OF MEASUREMENT ON DECISIONS MADE WITHIN BRIEF EXPERIMENTAL ANALYSES OF READING FLUENCY

Intervention researchers often use curriculum‐based measurement of reading fluency (CBM‐R) with a brief experimental analysis (BEA) to identify an effective intervention for individual students. The current study synthesized data from 22 studies that used CBM‐R data within a BEA by computing the standard error of measure (SEM) for the median data point from the baseline and intervention data. The median CBM‐R score from the intervention that the authors of each study identified as most effective fell within the SEM (68% confidence interval) of the baseline data approximately 30% of the time, but the ranges for the two author‐identified most effective interventions overlapped over 75% of the time. Extended analyses were consistent with the BEA results for approximately three‐fourths of the instances after considering the SEM of the baseline and intervention phases. Using matched passages did not improve the overlap of the ranges, but there was less overlap when the study used three data points per condition. Results emphasize the importance of considering SEM of CBM‐R data when comparing interventions within a BEA. Further implications for practice and future research are included.     

Self‐report objective measures of personality for children: A review of psychometric properties for RQC

Knoff (1995) indicated that Referral Question Consultation (RQC) can be applied to personality assessment and suggested several self‐report objective measures that could be consistent with this approach. The current article reviews the tools mentioned by Knoff, including the Children's Personality Questionnaire, The Millon Adolescent Clinical Inventory, The Minnesota Multiphasic Personality Inventory–Adolescents, The Personality Inventory for Youth, and The Self Report of Personality (SRP) from the Behavior Assessment System for Children. Each review addressed the reliability of the scales and composite scores, validity, usefulness of results for planning interventions, the empirical basis for analyses of individual items, and whether each measure accounted for response biases. The appropriateness of each for use with RQC, and individual strengths and weaknesses varied considerably. Therefore, practitioners should keep each test's limitations in mind when using it for intervention planning, and future research is needed to validate the tools for this purpose. © 2002 Wiley Periodicals, Inc.     

Relationship of reading fluency assessment data with state accountability test scores: A longitudinal comparison of grade levels

The No Child Left Behind Act of 2001 mandated statewide accountability testing and focused the accountability conversation on reading. Therefore, the current study examined the relationship between curriculum‐based measurement for reading (R‐CBM) and state accountability test scores, potential grade differences in relationship magnitude, and differences in relationship magnitude among R‐CBM and Maze as they compare to state test scores. Data for 5,472 students in Grades 3, 5, 7, and 8 were correlated and resulted in corrected coefficients that ranged from .51 (eighth graders) to .71 (third graders) for R‐CBM and .49 (eighth graders) to .54 (seventh graders) for Maze. The coefficients between R‐CBM and state test scores were significantly larger for third and fifth graders than those for eighth graders. No significant differences in magnitude were found between the correlation coefficients for state test scores to R‐CBM and to Maze among seventh or eighth graders. Potential implications and suggestions for future research are included. © 2006 Wiley Periodicals, Inc. Psychol Schs 43: 527–535, 2006.     

Relationship between pre‐intervention data and post‐intervention reading fluency and growth: A meta‐analysis of assessment data for individual students

Curriculum‐based measurement is commonly used within a response‐to‐intervention framework to assess the effectiveness of intervention and to triage students into intervention tiers (e.g., the lowest 10% receive a Tier 3 intervention, and those in the 11th to 25th percentiles receive a Tier 2 intervention). We conducted a meta‐analysis of 18 studies to examine the relationship between pre‐intervention assessments and post‐intervention level and growth in reading fluency. The results indicated that several pre‐intervention measures were moderately related to post‐intervention fluency, but only a percentage of comprehension questions answered during baseline assessments, reading fluency age or grade‐based standard scores (SS), and word attack SS resulted in even a small to moderate relationship with reading growth. Moreover, there was no significant difference between the correlation of any two pre‐intervention measures with reading growth, which suggested that all of the measures were equally poorly related to reading growth. Implications for research and practice are discussed. © 2012 Wiley Periodicals, Inc.
