The purpose of this study was to determine the effects of intensified physical education sessions on adolescents ages 11-16 years. They were divided into two experimental groups--high-intensity running group (HIRG) and high-intensity jumping group (HlJG)--and a control group (C). During the sessions, heart rate (HR) was monitored. There was no significant difference between mean HR for HIRG and HIJG, while the mean HR was significantly lower for C (p < .001). For both HIRG and HIJG, the mean HR was significantly higher for girls than for boys (p < .001). Our results suggested that these intensified physical education lessons require a high percentage of maximal HR in adolescents and can be used to improve aerobic fitness. 相似文献

Multiple-choice questions (MCQs) play a key role in standardised testing and in-class assessment. Research into the influence of within-item response order on MCQ characteristics has been mixed. While some researchers have shown preferential selection of response options presented earlier in the answer list, others have failed to replicate these results. This paper investigates a possible explanation for these mixed findings by assessing the influence of distractor strength on MCQ response order effects. A real-world assessment was administered to 232 undergraduates in which the response order within items was systematically varied. A generalised multilevel model was then used to show a significant interaction between distractor strength and response position with regard to response behaviour. Furthermore, the effect was found to be independent of student ability. These findings have implications for MCQ test construction, minimising the negative consequences of MCQ test exposure and promoting improved test-taking strategies. 相似文献

The consensus problem for networks of multiple agents consists in reaching an agreement between certain coordinates of interest using a distributed controller. It may be desirable that all the agents find a consensus at a given desired leader coordinate (Leader Follower Consensus Problem LFCP), or it may be only necessary that they agree at a certain coordinates value (Leaderless Consensus Problem LCP). Consensus has many practical applications in robot networks systems, where the interconnection of the agents may present variable time delays, hence rendering the stability analysis and control design more complex. Another problem that may arise is the possible lack of velocity measurements. In this work, a Proportional plus damping injection (P + d) controller together with a linear velocity observer is introduced. Our approach is able to solve both the LFCP and the LCP in networks of robots modeled as undirected weighted graphs with unknown asymmetric (bounded) variable time delays. Local (semi global) asymptotic stability is proven and simulation results are provided to test the performance of the proposed scheme. 相似文献

This paper investigates the definitions and onset of an old person in South-Western Nigeria. Conventionally, anyone who has reached the age of 60 or 65 years is regarded as the onset of an old person. But on contrary, this recent study is strongly emphasizing that 50 years and above is the onset of an old person in South-Western Nigeria. Obviously, the definitions and onset of an old person are controversial, yet, revealing in this paper. The study captured 13 Local Government Areas in Lagos state while 11 Local Government Areas were covered in Oyo state. The study employed focus group discussions (FGDs) and in-depth interviews (IDIs). However, 938 old persons were interviewed through questionnaire administration in Lagos and Oyo states of South-Western Nigeria. The univariate, FGDs, and IDIs were employed in the analyses of this research. The major findings of this study are the following: firstly, that there are different dimensions of the definitions of an old person that include frailty, inactivity, loss of strength, respect, blessedness, sickness, growing old, and inability to do hard work. Secondly, that someone who has reached the age of 50 years and above can be regarded as an old person, which is the onset of an old person in South-Western Nigeria society. On the basis of earlier findings, the study hereby recommends that anyone who has attained the age of 50 years and above should be recognized, regarded, and honored as an Elder by the State Government of South-Western Nigeria society where they are presently residing. 相似文献

This study adopts a public value perspective to examine the eHealth services deployed by national and regional governments to contain the coronavirus (Covid-19) pandemic, including symptoms checkers, information portals and contact-tracing applications. We analyse 50 cases of eHealth applications adopted in 25 European Economic Area (EEA) and outline how these systems and technologies map against four dimensions of public value: user orientation, participation, legality and equity. Our findings reveal that the public value of the eHealth applications adopted in the context of the current pandemic is affected by both endogenous and exogenous factors that undermine their ability to improve the quality of healthcare services and social wellbeing. We conclude by suggesting areas for further research to address such factors and the trade-offs emerging between different dimensions of public value. 相似文献

The aim of the article is to investigate the level of job satisfaction among cataloger librarians in university libraries in Nigeria. Eighty-six catalogers from 29 university libraries in Nigeria participated in the survey. A questionnaire was used for data collection, which was e-mailed to catalogers. Overall, 86% of the catalogers surveyed were very or somewhat satisfied with their current job. The findings revealed that catalogers in university libraries in Nigeria are dissatisfied with dimensions such as roles and responsibilities, workplace culture, rewards (salaries/benefits), and professional development. On the other hand, they are satisfied with administration and supervision, performance evaluation, and opportunities. 相似文献

Assessment in institutions of higher learning has been researched worldwide. However, there are gaps in research exploring the implications of assessment practices for learners’ access to the kind of knowledge enabling them to participate in their communities’ socio-economic transformation. This is the case in the African Great Lakes region, including Rwanda. This paper investigated the assessment practices at the University of Rwanda-College of Education to establish whether they enable students to access powerful knowledge for socio-economic transformation, which promotes critical thinking and creativity, or the knowledge of the powerful, which promotes memorization of knowledge produced by experts. The study adopted mixed methods, where 361 questions from 20 examinations papers for 2014/2015 and 2015/2016 academic years were analysed using Bloom’s revised taxonomy. Interviews with lecturers and group discussions with students were conducted. The findings revealed that assessment practices heavily encourage the knowledge of the powerful, with limited focus on the socio-economic transformative knowledge. Such practices are unlikely to lead to national socioeconomic transformation, which the government expects from education. The paper recommends revisiting assessment practices in Rwandan higher education to instil in the graduates the required knowledge for active contribution to socio-economic transformation. 相似文献

The study presents the results of a project in which a series of digital games were used for teaching Mathematics to first, fourth, and sixth-grade primary school students (ages 6–7, 8–9, and 11–12). Mathematics was selected as the teaching subject because of the difficulties students face in understanding basic math concepts. Although digital games are used quite extensively for educational purposes, they are scarcely used for teaching Mathematics. The games were developed by the classes' teachers using Microsoft's Kodu Game Lab. The learning outcomes were compared to two other groups of students. The first was taught using the model proposed by Driver and Oldham while the second was taught conventionally. Data was collected using questionnaires and evaluation sheets. A total of 201 students participated in the study coming from three schools in Athens, Greece. Results indicated that students in the games group outperformed, in most cases, students in the other groups. Students' views for the games were highly positive. The implications for software engineers and education administrators are also discussed. 相似文献

Electroencephalogram Recordings Indicate That More Abstract Diagrams Need More Mental Resources to Process 下载免费PDF全文
There is considerable interest in the cultivation of student graphic literacy among educators and researchers, especially in the sciences. Previous research, however, has shown that many students manifest difficulties in using diagrammatic representations. One explanation that has been proposed to account for these difficulties is that certain forms of diagrams may be more demanding of mental effort to use. Although there had been behavioral evidence to support this explanation, neurophysiological evidence had not confirmed it. Here, we provide evidence, from electroencephalogram recordings of brain activity focusing on the P3b component, that more abstract diagrams (such as graphs) demand greater mental resources to process compared to pictures and text—even when amount of detail has been accounted for. Our results provide initial neurophysiological evidence for the impact of cognitive cost on student learning behaviors and outcomes. Consideration of this finding is important in pedagogical design and, more broadly, in media communication. 相似文献
