This study describes the context for the development of a tool to formatively assess information technology skills of students. The tool provides a reliable and valid assessment of word processing competency, utilizing automation to apply the test instrument via the Microsoft Office package. Tests can be designed directly by tutors, and delivered via a network. Evaluation of the tests suggests that immediate automated testing is preferred by students compared to a traditional written test. There is evidence that the tool improves the IT skills of its users, whereas a traditional written test has no such beneficial effect.  相似文献

In this study of the origins of individual differences in theory of mind (ToM), the Environmental Risk (E-Risk) Longitudinal Twin Study sample of 1,116 sixty-month-old twin pairs completed a comprehensive battery of ToM tasks. Individual differences in ToM were striking and strongly associated with verbal ability. Behavioral genetic models of the data showed that environmental factors explained the majority of the variance in ToM performance in this sample. Shared environmental influences on verbal ability had a common impact on ToM and explained more than half the phenotypic correlation between these two skills. Possible underlying proximal mechanisms are discussed, including maternal speech and mind-mindedness, sibling interactions, and peer influences.  相似文献

The purpose of this study was to quantify the reliability of kinematic and kinetic variables using a sample of pre-peak-height-velocity (PHV) male athletes sprinting on a non-motorised treadmill. Following variables were measured and their normative data presented, average and peak velocity, average and peak power, average and peak horizontal force, average and peak vertical force, average step frequency, average step length, average work. Twenty-five participants performed three 5-s all-out sprints from a standing split start on a non-motorised treadmill on three separate occasions. Per cent change in the means (-3.66 to 3.35%) and coefficients of variation (0.56–7.81%) were thought reliable for all variables. However, average step rate, average horizontal force and average vertical force did not meet the standards (≥0.70) set for acceptable intraclass correlation coefficients (ICC). Due to the homogeneous group, it was expected to receive low ICC values. Therefore, youth sprinting performance can be tested reliably on a non-motorised treadmill, especially if the per cent change in the mean and CV are deemed the important reliability measures. Normative data are given for the participant’s age as well as their maturity level for kinematic and kinetic variables.  相似文献

The aim of this study was to investigate how the type of contact influences physiological, perceptual and locomotive load during a simulated rugby league match. Eleven male university rugby league players performed two trials of the rugby league movement simulation protocol for interchange forwards with a traditional soft tackle bag and a weighted tackle sled to replicate contact demands. The interchange forward-specific simulation was chosen given the contact frequency is higher for this group of players compared to whole match players. Locomotive rate, sprint speed, tackle intensity, heart rate (HR) and rating of perceived exertion were analysed during the first and second bouts that replicated two ~23 min on-field passages. Countermovement jump (CMJ) was measured before and immediately after each trial. More time was spent in heart rate zone between 91 and 100% HRpeak during the first (effect size ± 90% confidence interval: 0.44 ± 0.49) and second bouts (0.44 ± 0.43), and larger (0.6 ± 0.69) decrements in CMJ performance were observed during the sled trial (5.9, = 4.9%) compared to the bag trial (2.6, = 5.4%). Changing the type of contact during the match simulation subtly altered both the internal and external loads on participants. Using a standard tackle bag results in faster sprint speed to contact, but lower overall high-intensity running. Conversely, a heavier tackle object increases the internal load and results in greater lower limb neuromuscular fatigue as reflected by the decrease in CMJ performance.  相似文献

While Northern Ireland strives to build a shared society, the current reality is that everyday experiences are still shaped by division along ethno‐religious lines. This is particularly pronounced in the education system, where more than 92% of pupils attend separate schools. Within the predominantly separate education system, however, exists a small collection of schools which cater to a more heterogeneous pupil body and offer the opportunity for young people from both communities to meet and interact, and potentially develop cross‐group friendships. The present study compares the network‐based cross‐group friendships within two such school types; an integrated and a separate post‐primary school. These schools boast a distinct ethos yet they similarly enrol students from Catholic and Protestant backgrounds. Findings reveal that both schools show a high level of interconnection between pupils; however, the integrated school, with an ethos that openly supports social cohesion, shows a greater tendency towards cross‐group interactions and best friendships than those found within the separate school. In line with contact theory, these findings suggest that it may not be enough to simply create opportunities for intergroup contact but that optimal conditions, such as institutional support, may be a prerequisite for positive relationships to flourish. Implications for educational policies designed to promote greater cross‐community contact are discussed.  相似文献

Researchers in the educational field have investigated how a caring adult can best provide mentoring support to youth placed at risk and what functions a mentoring program should serve to promote healthy mentoring relationships. However, the perspective of mentors rarely has been sought to elicit their evaluation of a mentoring program or recommendations for programmatic change. The purpose of this article was to investigate the views of university students serving as mentors in high‐need high schools or community centers. We asked 49 students, primarily undergraduates across a range of liberal arts disciplines, who were participating in a university‐based service‐learning mentoring program for youth attending high‐poverty high schools: (a) what activities they engaged in with mentees, (b) how they benefited from the mentoring program, and (c) how they perceived the program and what recommendations they had for change. Findings revealed specific suggestions that mentoring program coordinators can adopt to address mentors’ concerns and promote sustained, durable mentoring relationships for youth.  相似文献

Within a multitiered system of support (MTSS), students who struggle to learn mathematics often receive core instruction and supplemental intervention in different settings, with different teachers and different sets of curriculum materials, all of which can result in poor alignment. This curriculum crosswalk describes how three sets of materials commonly used to provide core instruction and intervention differ with regard to mathematics practices and vocabulary. The results indicate that there is little overlap among all three programs for the majority (n = 6) of the mathematics practices, and very little overlap in mathematics vocabulary (ranging from 6.3 to 24 percent). We also provide a set of research-based instructional recommendations intended to help teachers address gaps and improve alignment of core instruction and intervention.  相似文献

We investigated whether the layout of type in two popular children’s reading schemes was suitable for the intended reading age. 120 children read four passages of text that adopted the typography of four reading stages in each of the two schemes. The size and spacing of the texts decreased with successive stages as the intended reading age increased. The reading speed of children aged 5 to 7 years decreased as the text size decreased: in particular, these children read fastest the text designed for 5 and 6 year olds. Older children aged 8 to 11 years were neither assisted nor disadvantaged by text size. Children of all ages, particularly those susceptible to visual stress, were found to make more errors on the smaller than on the larger text. We conclude that the reading development of some children might benefit from a larger text size and spacing than is currently the norm, and that no children would be disadvantaged by such a change.  相似文献
