QFD理论在高校创新创业教育课程设计中的应用研究

我国当前高校创新创业教育课程存在一定的不足,尽管有研究提出了改进对策或建议,但其提出过程缺少科学系统的分析工具,且所提出的对策措施千校一面,缺乏针对性。造成这种状况的本质原因在于未对课程对象(顾客)需求期望进行清晰准确的识别。质量功能展开(QFD)立足于顾客,能有效将顾客需求转化为产品/服务设计要求。因此,将QFD与高校双创课程设计相结合,提出创新创业课程质量功能展开模型(ICQFDM),通过"顾客需求—教学规划"与"教学规划—教学管理"两级质量屋,将顾客对于双创课程的要求转化到课程设计要求中。以南京已开展创新创业课程且互为竞争对手的2所财经类院校为例,演示模型的具体运用过程。结果显示:2所高校创新创业课程设计路径存在较大差异。ICQFDM的提出为高校建设创新创业课程提供了可操作的分析框架,各高校可结合不同实际情况,制定适用于自身的课程建设措施。     

Testing and ideology: policy debates about literacy assessments for Colorado’s bilingual students

ABSTRACT

The Colorado Reading to Ensure Academic Development Act requires grade-level attainment in literacy in English for students in grades K-3. Its practical outcome, however, has been to pressure schools with bilingual programs to shift their instructional language allocations towards more English in the early grades. Proposed rule revisions debated by the state Board of Education sought to facilitate testing in students’ language of instruction for those in bilingual programs. Analysis of written and verbal opposition to the proposed rule revisions demonstrates the persistence of insidious ethnoculturalist discourses opposing bilingual education as well as the cooptation of liberal multiculturalist discourses that, while framing bilingualism as an asset, argue that it is underdeveloped in bilingual programs that do not include English instruction from the outset. Given that bilingual instruction has demonstrated time and again that it benefits students acquiring English in schools, such new discursive turns pose a threat that must be recognized to fend off further legislative and regulatory attempts against bilingual education.     

智慧教育转型与变革

智慧教育不仅是智能技术在教育中的应用,更是智能时代教育的全面转型与变革。文章结合智能时代的三大发展趋势:即人机物三元融合、主动智能服务与人机结合的分布式认知,从基础环境、智能形态、培养模式、教育生态、育人目标五个维度提出了智慧教育转型与变革的关键所在,包括拥有主动智能的教育环境、人机协同的教育智能、大规模个性化的人才培养模式、虚实融合的教育新生态和智能时代的创新人才培养。在此基础上,面向智慧教育转型与变革的实践落地,提出了三点关键建议,包括建立数据无缝流转的生态体系、推进教育公共服务模式创新、高度重视专业性的教育服务,期望为智能时代智慧教育的转型与变革提供一定的参考与应用启示。     

矩阵方程组异类约束解的MCG1-3-5算法

借鉴求线性矩阵方程组同类约束解的MCG算法（修正共轭梯度法）,建立了求多个未知矩阵的线性矩阵方程组的一种异类约束解的MCG1-3-5算法,证明了该算法的收敛性。该算法不仅可以判断矩阵方程组的异类约束解是否存在,而且在有异类约束解,且不考虑舍入误差时,可在有限步计算后求得矩阵方程组的一组异类约束解;选取特殊初始矩阵时,求得矩阵方程组的极小范数异类约束解。同时还能求取指定矩阵在该矩阵方程组异类约束解集合中的最佳逼近。算例表明,该算法有效。     

A theory of instruction for introductory programming skills

ABSTRACT

Background and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.

Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.

Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.

Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.

Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding.

宋明儒学之分系问题及其诠释学上的意涵

本文的重点不在于探讨宋明儒学分系理论的优劣 ,而是希望在不同理论的陈述介绍之外 ,通过一个本性诠释学的观点 (成中英 )将之综合。这种综合的作法并非取消个别分系理论的特殊性和重要性 ,而是在另一种不同的基础上赋予这种理论的差异以一种新的意义。从狭义的角度来看 ,宋明儒学的理论发展可得到一诠释循环下的新论述 ;从广义的角度而言 ,在同一讨论领域内的不同理论也可透过循环之观点获得一种新安排与新秩序。
