Validation is both a process and a function within Company ABC. Using the human performance technology (HPT) process, interventions were prescribed to address identified performance gaps. Forecasting an annual return on investment (ROI) based on goals yielded a ROI of 168%. Data collected for the first quarter of 2009 yielded a calculated ROI of 326%. This study discusses the HPT process and what was done to achieve the results. 相似文献

We report 2 experiments that assess factors potentially responsible for a proactive interference with the sensitivity of a mother's response to infant signals. Using a version of the "learned helplessness" paradigm, mothers' performance on a solvable task was assessed following pretreatments that involved exposure to an infant cry but that differed in the mothers' ability to exert control over the termination of the cry. Each experiment explored the role of varying attributions made by a mother in the development of, or the reversal of, the helplessness phenomenon. The first experiment addressed the question of whether a specific intervention (i.e., providing the mother an attribution for failure) can reduce the debilitating effect of prior experience with failure. The results indicated that the debilitating effects associated with previous failure were reversed for the 16 mothers assigned to the intervention group. 40 mothers participated in the second experiment, which varied attributions assigned to an identical cry stimulus (i.e., the cry was produced by an "easy" vs. a "difficult" infant). This experiment assessed the effect of varying attributions on the mothers' ability to terminate the cry. We found that mothers pretreated with inescapable cries and those receiving the experimental manipulation of attributing the cry to a "difficult" infant showed debilitated performance in stopping the cry when given the opportunity. We propose that models based on learned helplessness theory have value in the study of caregiver-infant relationships, in particular, caregivers' perceived and objective effectiveness in responding to an infant's signals. 相似文献

Reading is fundamental to science and not an adjunct to its practice. In other words, understanding the meaning of the various forms of written discourse employed in the creation, discussion, and communication of scientific knowledge is inherent to how science works. The language used in science, however, sets up a barrier, that in order to be overcome requires all students to have a clear understanding of the features of the multimodal informational texts employed in science and the strategies they can use to decode the scientific concepts communicated in informational texts. We argue that all teachers of science must develop a functional understanding of reading comprehension as part of their professional knowledge and skill. After describing our rationale for including knowledge about reading as a professional knowledge base every teacher of science should have, we outline the knowledge about language teachers must develop, the knowledge about the challenges that reading comprehension of science texts poses for students, and the knowledge about instructional strategies science teachers should know to support their students’ reading comprehension of science texts. Implications regarding the essential role that knowledge about reading should play in the preparation of science teachers are also discussed here. 相似文献

This study describes the development and validation of a science and engineering (S/E) career interest survey (CIS). This 56 question survey was developed to measure the overall S/E career interests of 7th through 9th grade students. In the CIS, a S/E career is characterized as one which requires the completion of at least a four-year college program with a major in science, science education, or engineering. The CIS is divided into four major parts. In Part I (30 questions), students are expected to select from occupational activities, while in Part II (20 questions) they are to select from various occupations. Part III (5 questions) and Part IV together make up the CIS internal verification scale. The CIS test-retest reliability coefficients for one week and eight months were calculated as 0.96 (n = 57, grades 7–9) and 0.78 (n = 1937, grade 8), respectively. The KR-21 estimate for the CIS was calculated as 0.92. Criterion-related validity coefficients were calculated in two ways: (a) CIS scores were correlated with the Kuder GIS science subscale (r = 0.75, n = 45, grades 7–9), and (b) CIS scores were correlated with a CIS internal verification scale (r = 0.59, n = 127, grades 7–9). Evidence to support the construct validity of the CIS was collected by two methods: (a) for 7–9 grade students (n = 45), the CIS score was found to correlate 0.75 with the scientific subscale and ?0.42 with the artistic sub-scale, of the Kuder GIS. (b) the second method compared the scores of known groups. Test results for students in grades 7-9 (n = 127; n = 1937) showed a statistically significant difference between the scores of boys and girls on S/E career interest. The readability of the CIS was seventh grade level. 相似文献

AbstractLateral ankle sprains (LAS) are one of the most common musculoskeletal injuries and as a response, clinicians often use external ankle taping prophylactically to reduce the prevalence of injuries. External ankle taping techniques have been shown to significantly reduce passive ankle range of motion; however, there is limited research on the effects of external ankle taping on lower extremity kinematics or kinetics during sport specific tasks. Therefore, our objective was to compare the effects of external ankle taping on ankle, knee and hip kinematics and kinetics compared to no taping during an anticipated sidestep cutting task and a straight sprint task. We conducted a cross-over laboratory study with 16 healthy males. Three-dimensional kinematics and kinetics were collected with a motion capture system and in-ground force plate during 5 trials of a sprint and anticipated side-step cut with or without external ankle taping. Group means and associated 90% confidence intervals were plotted across 100 data points for each task, significance being identified when the confidence intervals did not overlap for three consecutive data points. No significant kinetic or kinematic differences were identified between conditions for the tasks. External ankle taping does not influence lower extremity biomechanics during a control cutting task. 相似文献

A co-operative project between the Association of Learned and Professional Society Publishers and Queen's University, Belfast, supported by the Electronic Libraries Programme, was set up to create a website and host the publications of five learned societies on an experimental basis. In the light of the experience gained, societies who have not taken the first steps in providing electronic services for their members and subscribers are offered advice on the structure, setup, and service requirements for their first website. 相似文献

The need for schools to support children and young people's mental and emotional health is increasingly emphasised in policy initiatives, yet the role of teachers in this has been under explored. This paper reports findings from qualitative, semi‐structured interviews with 14 school staff at eight secondary schools in England, examining emotional health and well‐being (EHWB) activities in which they were involved. Three emergent themes are discussed: (1) a strongly held belief that teaching and EHWB are inevitably linked; (2) a perception that many colleagues outside the study sample are reluctant to engage in EHWB work; and (3) a concern that teachers’ own emotional health needs are neglected, leaving them unable or unwilling to consider those of pupils. The findings endorse whole‐school approaches to emotional health, with a focus on teachers’ training and support needs and clearer aims, including consideration of how such work fits with the broader goals of schools. 相似文献
