Priming urban learners' attitudes toward the relevancy of science: A mixed-methods study testing the importance of context

The development of three-dimensional learning among all K-12 student demographics remains a prominent goal for the field of science education. However, substantial research in science teacher education for urban populations showcases hurdles to overcome in order to achieve this goal, particularly for elementary teachers. Research shows that urban elementary teachers are often ill-prepared to develop a type of science pedagogy responsive to students' learning needs. The fidelity of such pedagogies that these teachers adhere to when trying to implement such a requested content–relationality between these populations and how their local contexts can be used as sites to learn science in relevant ways are often not fully realized, as well. Given that science achievement gaps exhibit racial disparities starting in primary grades and attitudes toward science have been shown to affect academic achievement and motivation, we argue that one way to ameliorate, in at least an incremental way, this disparity is to design novel learning experiences to prime students to see the relevancy of science in their local contexts before such three-dimensional designed learning is set to occur. In this research, we leveraged the immersive nature of Virtual Reality 360 videos and present a design-based research iteration testing how this novel technologically enhanced learning experience may have influenced close to 400 urban elementary students' attitudes toward science around those attitudes labeled as “behavioral beliefs” by the field. Using a concurrent, convergent mixed-methods design with a two-way multivariate analysis of covariance quantitative data set triangulated with students' qualitative self-reports that were transformed into quantitative preponderances in graphic form, the data support that our design iteration emphasizing the importance of context as a design focus can prime students who struggle to see science as relevant to change their attitudes. Implications are discussed around relationality, novel technological affordances, and the use of local contexts as learning resources.     

Unity3D下构件化虚拟仪器功能实现方法

三维虚拟现实漫游仿真和虚拟仪器实验过程仿真是目前两种主要仿真手段,前者能够很好地模拟真实实验场景,后者则能更好地仿真实验细节。为了解决传统虚拟实验交互性弱、开发周期长等问题,提出了一种Unity3D下的构件化虚拟仪器功能实现方法。首先在Unity3D平台上开发多种标准化、可复用的虚拟仪器;然后将虚拟仪器引入虚拟现实场景中,并通过基于事件中心的观察者模式实现虚拟仪器的通信和数据流动;最后,依据构建的虚拟仪器开展典型机械工程测量实验。结果表明,与传统虚拟实验相比,该方法具有更好的真实性、交互性,同时构件化的思想缩短了开发周期。     

儿童焦虑与父母教养方式关系的调节变量研究

研究综合了来自中国大陆18570名3-12岁儿童的焦虑与父母教养方式相关的30项研究的数据,通过元分析的方法考查了二者相关的强度,并分析影响相关强度的因素。从总体上来说,儿童焦虑与父母教养方式存在弱相关;父母教养方式类型、儿童年龄、父母性别会对二者关系产生调节作用。建议在教养儿童过程中要采用正向的教养方式,要给予年幼儿童充分的独立自主的权利和自由,鼓励父亲参与教养,这有利于降低儿童的焦虑水平。
