小学生STEAM学习能力:时代价值、内涵认识及评价框架

STEAM教育的本质是一种跨学科学习,强调21世纪学习者的学习能力、实践能力、创新能力的培养.它对提升我国国际竞争力、服务教育现代化和教育强国的建设,深化基础教育课程教学改革、扎实推进素质教育,建设终身学习型社会、实现人的可持续发展教育具有重要时代价值.小学生STEAM学习能力是在教师引导下,学生运用跨学科知识正确认识和理解复杂性问题情境,有计划、创造性地解决实际问题所表现出来的知识、技能和态度的综合.然而,当前学界对于小学生STEAM学习能力及其评价的研究尚付阙如.为此,研究基于理论探索和实证研究,初步构建小学生STEAM学习能力的评价框架,包括知识基础、情境理解、问题解决、态度倾向等4个一级指标,学科知识、跨学科知识等13个二级指标,通过进一步探析各指标内涵和行为表现,以期为建立更系统、更完善的小学生跨学科STEAM学习能力评价标准提供借鉴与参考.     

论当前高校课程思政建设策略

高校对于课程思政建设过程中的若干问题已经形成广泛共识,但是仍有一些问题,学界还较少论及。对此,文章提出当前高校课程思政建设的“三大策略”:应坚守教书育人这一初心;应与一流课程建设紧密融合;应以服务国家战略为导向。在课程和专业教学日益国际化的环境下,教学实践中当做好国际理解教育与爱国主义教育相结合、跨文化教育与文化自信教育相结合、使命教育与美育相结合。     

基于偏序集的高校图书馆服务质量评价模型研究

[目的/意义]科学、客观地对服务质量进行评价,有助于高校图书馆相关工作的持续改进,从而为人才培养、科学研究工作提供强有力的支撑。[方法/过程]利用偏序集理论,建立了高校图书馆服务质量评价模型。首先选定了服务质量评价指标集,利用18所高校图书馆实际数据,通过因子分析法确定了评价指标权重顺序,然后基于偏序集构造Hasse图,最后通过对Hasse图的分析实现对高校图书馆服务质量的评价。[结果/结论]该评价模型可以有效克服传统评价方法受主观因素干扰大的不足,为高校图书馆服务质量评价提供了新思路。     

非英语专业英语口译教学探索与实践

目前,社会亟须既有相当的专业知识,又有口译技能的人才,因此本文提出了运用口译教学来提高非英语专业学生的英语综合能力,并以背景知识、行为主义理论和交际语言测试理论支撑,运用多媒体等作为教学手段,用两年的口译教学实践证明对非英语专业学生进行口译训练的可行性。     

高等职业院校与区域经济协调性评估实证研究——以北京、上海、天津三个直辖市为例

高等职业院校与区域经济之间的协调发展遵循“非协调—协调—非协调”的矛盾运动规律。通过分析高等职业院校与区域经济发展在三个产业上的布局关系,可以评估高等职业院校与区域经济之间的协调性。基于结构距离数学工具的使用,系统性地考察北京、上海、天津三个直辖市高等职业院校与经济之间的协调性特点,得出如下结论:北京应该适度发展偏向于第三产业的高等职业院校,以满足其经济发展的未来需求;上海应该重点发展偏向于第二产业的高等职业院校,扩大本科层次的职业教育培养;天津应该进一步整合高等职业院校资源,改变粗放型的高等职业院校发展模式。     

Weld Characteristics and NC Bending Formability of QSTE340 Welded Tube

The mechanical characteristics of the weld joint were investigated by tensile test, microstructure test, and microhardness test. The welded tube NC bending tests were carried out to evaluate the weld on the formability of the QSTE340 welded tube. The results show that the wall thinning degree, cross-sectional deformation and springback angle increase significantly as the weld line is located on the outside of the bend compared with that located on the middle and inside, and the welded tubes produce nearly identical performance as the weld line is located on the middle and inside. The wall thickening degree decreases much as the weld line is located on the inside of the bend. So the welded tube can acquire good bending formability as the weld line is located in the region away from the outside of the bend.

Observer-based fuzzy adaptive stabilization of uncertain switched stochastic nonlinear systems with input quantization

This paper proposes an observer-based fuzzy adaptive output feedback control scheme for a class of uncertain single-input and single-output (SISO) nonlinear stochastic systems with quantized input signals and arbitrary switchings. The SISO system under consideration contains completely unknown nonlinear functions, unmeasured system states and quantized input signals quantized by a hysteretic quantizer. By adopting a new nonlinear disposal of the quantized input, the relationship between the control input and the quantized input is established. The hysteretic quantizer that we take can effectively avoid the chattering phenomena. Furthermore, the introduction of a linear observer makes the estimation of the states possible. Based on the universal approximation ability of the fuzzy logic systems (FLSs) and backstepping recursive design with the common stochastic Lyapunov function approach, a quantized output feedback control scheme is constructed, where the dynamic surface control (DSC) is explored to alleviate the computation burden. The proposed control scheme cannot only guarantee the boundedness of signals but also make the output of the system converge to a small neighborhood of the origin. The simulation results are exhibited to demonstrate the validity of the control scheme.
