Benchmarking oral reading fluency in the early grades in Nguni languages     

《International Journal of Educational Development》2021

To prevent children from falling behind in the developmental sequence of reading, a shared vision of what reading success looks like is required. This paper provides the first benchmarks for early grade oral reading fluency that are necessary (albeit not sufficient) to read for meaning in three Nguni languages – isiZulu, isiXhosa and Siswati - belonging to the Southern Bantu family of African languages. In contrast with previous benchmarking methodologies, our approach is informed by a non-parametric analysis of longitudinal early grade reading assessment (EGRA) data, guided by reading development theory. The EGRA-type data used for this analysis is the largest compilation of data on early grade fluency in these languages, with comparative assessments for nearly 14,200 children. Analysing empirical regularities and reading trajectories, we identify a lower fluency threshold of 20 correct words per minute (cwpm) and an upper fluency benchmark of 35 cwpm for the early grades. These benchmarks contribute to guiding curriculum policy, provide specificity to improve tracking of literacy progress and address gaps in the literature on reading in African languages.  相似文献

Validation of a videogrammetry technique for analysing American football helmet kinematics     

Ann Bailey  James Funk  David Lessley  Chris Sherwood  Jeff Crandall  William Neale 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(5):678-700

ABSTRACT

Professional American football games are recorded in digital video with multiple cameras, often at high resolution and high frame rates. The purpose of this study was to evaluate the accuracy of a videogrammetry technique to calculate translational and rotational helmet velocity before, during and after a helmet impact. In total, 10 football impacts were staged in a National Football League (NFL) stadium by propelling helmeted 50th percentile male crash test dummies into each other or the ground at speeds and orientations representative of concussive impacts for NFL players. The tests were recorded by experienced sports film crews to obtain video coverage and quality typically available for NFL games. A videogrammetry procedure was used to track the position and rotation of the helmet throughout the relevant time interval of the head impact. Compared with rigidly mounted retroreflective marker three dimensional (3-D) motion tracking that was concurrently collected in the experiments, videogrammetry accurately calculated changes in translational and rotational velocity of the helmet using high frame rate (two cameras at 240 Hz) video (7% and 15% error, respectively). Low frame rate (2 cameras at 60 Hz) video was adequate for calculating pre-impact translational velocity but not for calculating the translational or rotational velocity change of the helmet during impact.  相似文献   

基于面向对象技术的旅游用地遥感识别     

罗开盛 《中国科学院大学学报》2020,37(4):490-497

利用国产GF-1卫星影像，以南京市为例，采用面向对象技术对旅游用地信息进行专题提取，研发出基于遥感手段的旅游用地信息提取方法和流程。研究结果如下：1）GF-1夏季影像4个图层（红、绿、蓝和近红外波段）方差的平均值（VI-Summer）是识别旅游用地的有效指标。2）旅游用地提取的制图精度和用户精度分别为83.33%和73.53%，表明基于GF-1卫星影像和面向对象技术的方法能够对旅游用地进行有效识别和监测。3）南京市的旅游用地总面积为137.34 km²。4）在空间分布上，旅游用地主要集中在长江以南地区，尤其是鼓楼区、雨花台区、建邺区、玄武区和秦淮区及其附近；而长江以北（江北）地区相对稀疏。本研究结果可为利用GF-1卫星影像快速有效地监管旅游用地提供技术支撑。  相似文献   

Affordances of using Multiple Videoed Events to construct a rich understanding of adult–child book readings     

Maria Nicholas 《International Journal of Research & Method in Education》2018,41(2):125-141

This paper explores the affordances of using video-based research to capture a multiplicity of events, along with multimodal representations when producing data related to adult–child book readings. In doing this we answer two questions: (1) why more than one event is needed when seeking a comprehensive collection of information for the purpose of analysis; and (2) why one mode of data production alone (e.g. audio recordings or note taking) is insufficient to record practice or interviews when richness is of priority. This research used three videoed events to produce data. These included videoing: (1) caregiver–child interactions during four shared book reading sessions, (2) interviews with caregivers immediately following each of the reading sessions and (3) video-stimulated discussions with caregivers within two months of the final shared book reading. In this paper, I contribute to discussions that highlight the affordances of using video-based research as a means of capturing the multimodal elements of an experience, which can contribute to the analysis and interpretation of data. I expand on this, however, to suggest that when coupled with a multiplicity of events, video-based research can be a means of pursuing richness via a method that has been criticized for its narrow subjectivity.  相似文献
