Understanding how student-constructed stop-motion animations promote mechanistic reasoning: A theoretical framework and empirical evidence

Previous studies have documented the promising results from student-constructed representations, including stop-motion animation (SMA), in supporting mechanistic reasoning (MR), which is considered an essential thinking skill in science education. Our current study presents theoretically and empirically how student-constructed SMA contributes to promoting MR. As a theoretical perspective, we propose a framework hypothesizing the link between elements of MR and the construction nature of SMA, that is, chunking and sequencing. We then examined the extent to which this framework was consistent with a multiple-case study in the domain of static electricity involving five secondary school students constructing and using their own SMA creation for reasoning. In addition, students' reasoning in pre- and postconstruction of an SMA was examined. Our empirical findings confirmed our framework by showing that all students identified the basic elements of MR, that is, entities and activities of entities, when engaging in chunking and sequencing. Chunking played a role in facilitating students to identify entities responsible for electrostatic phenomena, and sequencing seemed to elicit students to specify activities of these entities. The analysis of students' reasoning in pre- and postconstruction of SMA found that student-generated SMA has a potential effect on students' retention of the use of MR. Implications for instruction with SMA construction to support MR are discussed.

基于动态密度的空中交通复杂度计算方法研究

空中交通复杂度是指管制员所指挥空域的复杂程度。当航空器在空中的运行发生变化时,会产生大量的潜在冲突。本文基于成熟的空中动态密度模型,将诸多参数进行分类,并选出最能表征这一类的突出参数,建立新的复杂度计算模型。并参考管制员解决冲突时所产生的冲突负荷,分别从交通密度、交通进展、飞行流结构、交通混合四个方面进行修正,得出复杂度的计算公式。并利用雷达数据对某一空域进行测算,得出该空域的交通复杂度值。     

认知心理学视域下体育教学方法分类模式的创新及重构*

通过文献资料、逻辑分析等方法对我国体育教学方法分类体系进行研究,旨在构建以认知心理学知识观为分类标准的体育教学方法分类模式。研究表明:现有体育教学方法分类模式不能为体育教学实践提供足够的支持,运用认知心理学关于知识表征类型的相关研究成果对体育教学目标进行解构,构建了言语图表信息类教学方法、智慧技能类教学方法、认知策略类教学方法和信念类教学方法四级分类模式。该分类模式对促进体育教学方法分类研究的科学化和体育教师合理选择与运用教学方法具有重要意义。     

认知心理视角下的壮母语学生英语学习双迁移研究

壮母语学生英语学习有其自身特点,英语的学习过程是其母语、汉语和英语交互影响相互作用的过程,这三语间相互影响、作用或干扰导致其语言迁移的动态性、复杂和多样性。从心理认知的角度来研究壮母语学生英语学习中的语言迁移现象,可帮助我们进一步认清壮族学生语言习得中的障碍,把握好教学内容的难重点,帮助壮族学生克服语言学习中的困难。

Entrepreneurial opportunity and related specialization in economic ecosystems

Entrepreneurial ecosystems are most often defined as locally bounded networks of institutions and individuals that help entrepreneurs to identify and exploit market opportunities. However, a prerequisite of the ability to exploit an entrepreneurial opportunity is the existence of the opportunity to begin with. In this paper, we propose an approach to representing how entrepreneurial opportunities are embedded in a regional economy. The central methodological contribution of our paper is to introduce the concept of related specialization, which we define as the concentration of high interdependencies between specialized industries within a metropolitan region, relative to the national level of concentration. We find that related specialization is positively correlated with entrepreneurial outcomes across U.S. metropolitan areas. We use related specialization to make a first attempt at representing the trophic structure of an economic ecosystem. In a biological ecosystem, the trophic structure refers to energy-transfer relationships between different species. As introduced in this paper, we propose the analogy that, in an economic ecosystem, the trophic structure may be mapped in terms of the supply-chain relationships between industries within a region. We argue that these analytic tools can help policymakers more readily understand the opportunities that are imminently available to entrepreneurs in their local environments.     

主导逻辑：内涵、研究议题及未来展望

主导逻辑作为企业内部主导的一般管理逻辑,是指导企业制定相关战略决策、采取行动以快速响应外部动态复杂的市场环境的先导模块,对组织的战略决策、战略部署及战略执行具有指导作用而备受学界关注。本文以1986-2020年间与研究主题相关的211篇中外文文献为研究对象,在可视化分析的基础上归纳并整理现有研究成果,总结出主导逻辑的发展进程、概念内涵、形成机制、特性及类型划分等内容,并从与主导逻辑相关的企业竞争优势、价值创造及服务创新等热点议题对已有研究进行系统梳理,构建了主导逻辑理论知识框架。本文较为系统全面的梳理了主导逻辑理论现有研究,同时期望能够引起我国学者的关注,进一步探寻组织内部多元主导逻辑共存的内在机制,完善相关理论体系;补充服务主导逻辑对消费者影响的相关研究,丰富多类型主导逻辑的认知及作用机理;期望学界产出更多以具有我国国情特色的管理实践现象为研究土壤的高质量研究,从而为实践界在动态复杂的外部环境中构建主导逻辑提升组织竞争能力提供丰富的理论借鉴。     

“基于科学的企业”主导逻辑研究——以同方威视为例

本文采用探索性单案例研究的方法,从认知视角对中国情境下高校/研究机构衍生出来的“基于科学的企业”的创新发展主导逻辑进行了深入的研究和分析,研究发现,这类企业存在双主导逻辑并存的现象,分别为“需求归因”和“技术机会归因”逻辑,并且虽然在不同的阶段两种主导逻辑一以贯之,但企业对于两种主导逻辑的侧重即两种主导逻辑对企业的影响程度及方式是不断动态演化的。本研究还进一步探讨了双主导逻辑对“基于科学的企业”自有的不确定性风险的影响、双主导逻辑的演化路径以及对“基于科学的企业”参与和利用基础科学研究的影响以及其对中国情境下“基于科学的企业”相关研究具有的管理启示。
