Measurement,development, and stimulation of computational estimation abilities in kindergarten and primary education: A systematic literature review     

《Educational Research Review》2019

For several decades computational estimation is seen as an important topic in primary mathematics education. While previous narrative literature reviews on computational estimation summarized the available research on computational estimation abilities in students and adults, the present systematic literature review focuses on the measurement, development, and stimulation of computational estimation abilities in kindergartners and primary school children. Reviewing 28 studies revealed that these abilities were mostly investigated from 8-years old onwards by using a variety of measures. Age-related improvements in estimation performance and strategy use were observed in most studies. Only very few studies addressed the targeted stimulation of computational estimation abilities. The current review identified several gaps in the research literature, such as the absence of studies investigating the relationship between computational estimation performance and other basic numerical and mathematical abilities in children, and the paucity of longitudinal studies on the development of computational estimation ability.  相似文献

Comparison of standardized assessment methods: logistics,costs, incentives and use of data     

Natalie Simper  Brian Frank  Jake Kaupp  Nerissa Mulligan  Jill Scott 《Assessment & Evaluation in Higher Education》2019,44(6):821-834

Critical thinking, problem solving and communication are fundamental elements of undergraduate education, but methods for assessing these skills across an institution are susceptible to logistical, motivational and financial issues. Queen’s University conducted two research studies investigating the use of standardised tests to assess cognitive skill development across the institution. Synthesis of results from implementing the Collegiate Learning Assessment (CLA+), the Critical Thinking Assessment Test (CAT), and the HEIghten^TM test found that student test effort was a significant factor, and effort level correlated with performance at r?=?.33. Test incentives were also a significant factor; effort levels for the $25 financial incentive group were one standard deviation higher than effort for the in-class test group. A dedicated computer lab was the preferred option for computer-based testing. A paper-based test was found to be much simpler to administer, but test results were not available for a long time, therefore limiting the usefulness of data. The true cost of tests was greater than the price of the instrument; recruitment, training, proctoring and marking costs need to be included in the calculation. Generally speaking, alignment of test objectives with student or course objectives, and timeliness of data, were key for participation and motivation.  相似文献   

高等教育服务质量均值结构模型构建及实证研究     

胡子祥 《复旦教育论坛》2011,9(3):27-32

均值结构模型分析发现,高等学校教学工作水平评估前后高等教育服务质量、服务价值、满意感及行为意向的因子均值均存在显著差异,即从学生感知的视角来看,高等学校教学工作水平评估有助于高等教育服务质量的改进。高等教育质量管理部门应树立高等教育服务质量观,将高等教育服务质量、服务价值、满意感和行为意向等变量纳入高等教育质量评估指标,构建学生参与高等教育质量评估的机制,以进一步完善高等学校教学工作水平评估体系。  相似文献

历史地看待兴科举和废科举     

王炳照 《湖北招生考试》2006,(4)

中国兴科举1300年,废科举已逾百年,然而,兴科举的利弊得失,废科举的功过是非,却一直众说纷纭,莫衷一是,近些年似乎又成热点。掌握和运用历史主义的原则和方法,对此进行分析研究, 或许有助于讨论的深入。基于这种认识,提出“历史地看待兴科举和废科举”,即从科举考试形成发展的全过程和改革废除的全局的历史演变加以考量和评价,才能获得有益的进展。  相似文献   

Review: Acute phase reaction and acute phase proteins     

GRUYS E  TOUSSAINT M.J.M  NIEWOLD T.A  KOOPMANS S.J 《Journal of Zhejiang University. Science. B》2005,6(11)

A review of the systemic acute phase reaction with major cytokines involved, and the hepatic metabolic changes,negative and positive acute phase proteins (APPs) with function and associated pathology is given. It appears that APPs represent appropriate analytes for assessment of animal health. Whereas they represent non-specific markers as biological effect reactants,they can be used for assessing nutritional deficits and reactive processes, especially when positive and negative acute phase variables are combined in an index. When such acute phase index is applied to separate healthy animals from animals with some disease, much better results are obtained than with single analytes and statistically acceptable results for culling individual animals may be reached.Unfortunately at present no cheap, comprehensive and easy to use system is available for assessing various acute phase proteins in serum or blood samples at the same time. Protein microarray or fluid phase microchip technology may satisfy this need;and permit simultaneous analysis of numerous analytes in the same small volume sample and enable integration of information derived from systemic reactivity and nutrition with disease specific variables. Applying such technology may help to solve health problems in various countries not only in animal husbandry but also in human populations.  相似文献
