    • 摘要: STREAM作为微处理器上广泛应用于测试各种计算机的内存性能的基准测试程序,如何使得其在FT2000/4处理器上发挥高性能是具有挑战性的研究工作。对STREAM工具的各参数进行测试并且合理的设置参数数值可以使得程序性能大幅度提高。数据测试结果表明,优化后,并行程序的最高访存性能能达到13.93GB/s,对比优化前的最高访存性能提高了56.34%。

    • 摘要: 种植活动是幼儿亲近自然、探究动植物的科学探究活动,是幼儿园必不可少的活动之一。但幼儿园的种植活动普遍存在活动目标不够深入、幼儿的观察探究流于表面、缺乏连续性等问题。STREAM教育包括S(Science,科学)、T(Technology,技术)、R(Reading/Writing,读写)、E(Engineering,工程)、A(Arts,艺术)和M(Mathematics,数学)等方面,强调创造性地运用跨领域的视角与方法解决现实情境中的问题,能帮助幼儿在种植活动中连续、有效地深入探究。本文阐述了STREAM与幼儿发展及大班幼儿种植活动的联系,并以大班搭建豆苗藤架的活动为实例,提出了STREAM视域下大班幼儿种植活动的五项基本策略。

    • 摘要: Surface water quality is largely influenced by both natural processes and anthropogenic inputs. This study involves the characterization of the concentration of heavy metals of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn, and the sources of pollution in water and sediment of the Upper Litani River Basin (ULRB) in Lebanon. The investigation was performed during three seasons of rainy, mid-rainy spring and wet periods for two years during different flow rates. Sediments were characterized by a set of chemical analyses, cation exchange capacity (CEC), mineralogy of the sediments, X-ray diffraction (XRD), and Fourier transformed infrared spectroscopy (FTIR). To assess metal contamination in sediment, Consensus-Based Sediment Quality Guidelines of Wisconsin (CBSQG) were applied. The metals contamination in the sediments was also evaluated by contamination factor (Cf). The test results showed that the effect of seasonal variations was significant in the Upper Litani River Basin. Principal Compound Analysis (PCA) and Pearson’s correlation were also performed in this study to compare and determine the correlation between metals in water and sediments. The concentrations of Pb, Cd, Cu, Cr and Zn in all sediment samples are above the norms in winter, while Fe was increased in summer. The results showed that the importance of monitoring of changes of heavy metals values and physico-chemical characterization of different parameters could represent the possibility of a comprehensive assessment of negative pressures on the water and soil ecosystem of Litani River Basin during different seasons.

    • 摘要: STREAM跨学科教学虽然是在STEM与STEAM理念的基础上发展而来,但它对“智能+”教育时代的跨学科教学与人才培养具有更重要的价值。跨学科教学的本质在于“超越学科”,纵观当前国内外的课程改革和教学实践,已开始转向对学生的阅读、交互、探究、设计等“软技能”的培养。为此,基于2003-2022年国际期刊上发表的35项STREAM跨学科教学在线交互相关实验与准实验研究(实验样本涉及美国、中国、澳大利亚等7个国家的7955名教师与学生),元分析的结果表明:在线交互对STREAM跨学科教学具有显著正向强作用,尤其是对科学与技术等学科侧重、内容交互、虚拟和视频辅助的STREAM跨学科教学。这一元分析结果充分揭示了:STREAM跨学科教学在线交互在当前各类教学中具有较大的借鉴与应用价值,需要深入探索混合式STREAM跨学科教学深度交互、面向读写能力培养的STREAM跨学科教学资源整合、扩展现实技术辅助下的沉浸式跨学科教学实践、利用在线交互数据等,进一步驱动与落实STREAM跨学科教学的实践应用。

    • 摘要: 随着地理信息技术日新月异的发展,培养学生地理技术素养需要更加具有专业性的技术手段和方法.在地理教学中教师易忽略或缺少对中学生技术素养的培养,导致中学生地理技术素养非常缺乏.因此,本文结合STREAM教育模式,以"水污染处理模拟实验"为教学案例呈现高中生地理技术素养培养过程,旨在丰富STREAM课程案例和为地理教师开展相关教学提供参考.

    • 摘要: 一、什么是STREAM课程STREAM课程是在2010年美国学术竞争力委员会提出的STEM课程基础上,进一步融合艺术(Art)、读写(Reading/Writing)于科学(Science)、技术(Technology)、工程(Engieering)与数学(Mathematics)进行跨学科整合的课程。该课程的提出,旨在超越传统彼此割裂的分科课程,超越过往的45分钟课堂教学,强调聚焦某个特定的项目或任务.

    • 摘要: 在当前信息超载的冲击下,学习渠道逐步多样化,学生既要在课堂内进行系统化地学习,也能在生活中随时随地进行移动式学习,也称碎片化学习。碎片化学习导致大量信息涌入学生生活,学生所得知识看似丰富,但禁不起深究;而在学校经过系统化学习,学生所学知识看似专业性较强,但往往局限在书本里,无法实践,地理知识体系的建立缺乏支柱性基础。在现代信息社会,如何正视两种学习形态,将碎片化学习纳入学生知识体系构造的过程中,找到二者的交叉点和平衡点,是地理教育工作者应具备的开阔视野和超前意识。提出将新建构主义作为正式学习与非正式学习的互联桥梁,以STREAM理念作为地理核心素养培养的目标及落脚点,创新一种新的教学模式,使学生建构出个人化的知识体系。

    • 摘要: In data stream management systems (DSMSs), how to maintain the quality of queries is a difficult problem because both the processing cost and data arrival rates are highly unpredictable. When the system is overloaded, quality degrades significantly and thus load shedding becomes necessary. Unlike processing overloading in the general way which is only by a feedback control (FB) loop to obtain a good and stable performance over data streams, a feedback plus feed-forward control (FFC) strategy is introduced in DSMSs, which have a good quality of service (QoS) in the aspects of miss ratio and processing delay. In this paper, a quality adaptation framework is proposed, in which the control-theory-based techniques are leveraged to adjust the application behavior with the considerations of the current system status. Compared to previous solutions, the FFC strategy achieves a good quality with a waste of fewer resources.
