Using a database of allstudents in higher education in the UK in1995–1996, students with dyslexia and those withno reported disability were compared in termsof demographic properties, programmes of studyand academic attainment. Students with dyslexiaconstituted 0.42% of all students resident inthe UK. Their representation varied with age,gender, ethnicity and entrance qualificationsand with their level, mode and subject ofstudy. Students with dyslexia were more likelyto withdraw during their first year of studyand were less likely to complete theirprogrammes of study, although with appropriatesupport the completion rate of students withdyslexia can match that of students with nodisabilities. In addition, students withdyslexia who completed first-degree programmestended to gain a poorer class of honours thanstudents with no reported disability, but 40%obtained first-class or upper second-classhonours. In short, dyslexia may havedeleterious consequences for progression,completion and achievement in higher education,but it is by no means incompatible with a highlevel of success, given appropriate commitmenton the part of the students and appropriateresources on the part of their institution. 相似文献

高校评教是高校教育教学管理中的重要一环。文章针对目前已有的评教系统数据源单一、数据使用不充分、教师反馈不及时、师生互动性欠佳、学生评教积极性不高等现状,提出了一个高校评教系统新框架,以评教结果的使用范围为目的,反推出评教数据来源应具备多次性和多样性。每学期多次评教,实现教师与学生的互动,促进学生评教积极性,促进教师及时改进教学方法。评教人员除了学生之外,还应包括督导专家和往届生。 相似文献

Frame skipping in low bit video coding could significantly reduce the visual quality of reconstructed video. At the same time, if the complexity of the video sequence remains high for a long period, then driving up the long term average bit rate, the only resort of MPEG-4 Q2 rate control algorithm results in using a high quantization scale, which shows a poor visual quality of the reconstructed video. This paper analyzes the main causes of frame skipping in current MPEG-4 frame rate control scheme, and presents a new rate control algorithm based on the quadratic R-D model over a CBR channel. Key features of the present work are. 1) the bits allocated to each P-frame or B-frame are in proportion to its distance from the end of this GOP, i.e. more bits are allocated to the frames that are nearer to their reference Ⅰ -frame: 2) the target buffer level is changeable in the GOP, at the end of each GOP( five P-frames or B-frames), the target buffer level is linearly reduced from 1/2 to 1/4 of buffer size, to other frames, the target buffer level is set to 1/2 of buffer size: 3 ) a selective and judicious use of the reduced resolution mode, in addition to a modulation of the quantization scale parameter, is to control the average long term bit rate. Experimental results with different video sequences of varied complexity, encoded at low bit rates show better efficacy of the proposed algorithm than MPEG-4 Q2 rate control scheme, and the experimental results also show that the improved algorithm has significantly reduced the number of frame skipping, increased the overall PSNR, and improved the perceptual quality. 相似文献

创新驱动高质量发展是高等教育发展的未来,也是“双一流”建设质量发展指标研究的关键。在筛选和找出“双一流”建设质量的关键绩效指标(KPI)的基础上,提出了三个步骤的技术路线:一是分析影响因素,且按其重要性进行排列;二是按重要程度不同而精选出关键影响要素和绩效指标;三是更加重视整体研究和相关性研究,促进“以评促建”功能的实现。最后,对其中几个关键绩效指标(KPI)进行较为详细的诠释,包括高等教育毛入学率、生师比、学术声誉调查等。 相似文献

运用2011-2018年我国31个省级面板数据和北京大学编制的普惠数字金融指数,实证检验了数字金融对于我国区域创新效率的影响效应。研究发现:数字金融能够显著提升我国区域创新效率;从数字金融维度上来看,数字金融的覆盖广度和使用深度对于区域创新效率的促进作用显著,但是数字金融的数字化程度对于区域创新效率的促进作用不显著;分区域来看,数字金融对于东部地区的促进作用要优于中西部地区,覆盖广度对于东部地区的促进作用要优于使用深度,而中西部地区正好相反;数字金融对于区域创新效率的影响存在基于地区市场化程度和互联网普及率的单门槛效应,数字金融对于区域创新效率的促进作用只有在跨越相应的门槛值后才能发挥作用,而且该作用随着门槛变量水平的提高而逐渐增大。 相似文献

Effect of acquisition rates on off‐task behavior of kindergarten students while learning sight words
Matthew K. Burns Lisa N. Aguilar Kristy Warmbold‐Brann June L. Preast Crystal N. Taylor 《Psychology in the schools》2021,58(1):5-17
Assessing a student's acquisition rates (ARs) is a reliable way to determine how many new words should be taught in one lesson without reducing retention. Exceeding a student's AR can result in frustration and problem behaviors. The purpose of this study was to examine the effect of AR on the off‐task behavior of kindergarten students while participating in a commonly used sight‐word instruction video. Participants included 39 kindergarten students whose ARs were assessed before showing the sight‐word video. Behavior was measured as on‐ and off‐task using momentary time‐sampling with 10‐s intervals. Results indicated that students' time off task increased after exceeding their ARs, with a noticeable immediate increase. The implications and limitations of these results are discussed. 相似文献
