基于“大概念”的馆校结合STEM主题活动的设计剖析

近年来,以科技博物馆自身资源为依托开展的科学教育活动备受关注,其中以STEM教育为主题的馆校结合活动与日俱增,但其活动质量也出现良莠不齐的状态。笔者认为馆校结合的STEM主题活动在设计和实施上都需要符合当前科学教育领域中提倡的围绕“大概念”开展教学的教育理念。本文讨论了如何对STEM主题活动中的“大概念”进行解析,活动教学设计中的“大概念”体现在哪里,以及如何将科技博物馆资源融入活动设计中三个核心问题,并以山东科技馆馆校结合STEM主题活动的设计为例进行案例分析。     

Unpacking task-technology fit to explore the business value of big data analytics

Understanding how the application of big data analytics (BDA) generates business value is a persistent challenge in information systems (IS) research. Improving understanding of how BDA realizes business value requires unpacking theories to study the phenomenon. This study unpacks the task-technology fit (TTF) theory toward generating new and improved insights into the business value of BDA. Extant studies on TTF have mainly focused on traditional IT which is different from digital technologies like BDA that are malleable and dynamic. While TTF has primarily focused on how the technology meets task requirements, this study contends that tasks can also be structured to fit the functionality of technology. This study proposes a 2 × 2 matrix framework to explain how BDA and tasks interact. The framework indicates how the reconfigurability of tasks and the editability of BDA impact the fit between tasks and BDA. Future research should explore how the fit between tasks and BDA changes over time.

Intelligence and personality as predictors of divergent thinking: The role of general, fluid and crystallised intelligence

Two studies examined the relationships between measures of intelligence, personality and divergent thinking (DT) in student samples. Study one investigated the incremental validity of measures of IQ and fluid intelligence with the Big Five Personality Inventory with regards to DT. Significant relationships of DT to fluid intelligence, Extraversion and Disagreeableness were observed. Study two investigated the incremental validity of measures of fluid and crystallised intelligence (as assessed by a test of general knowledge) with the Big Five Personality Inventory with regards to DT. Hierarchical regression analyses revealed a significant relationship between crystallised intelligence and DT. The nature of the relationships of IQ, fluid and crystallised intelligence, in addition to personality traits to tests of DT were considered.     

关于大文件概念的再思考

国外的广义文件概念不同于我国的广义文件概念,为了避免混淆,我国才将国外的广义文件概念称为大文件概念.我国接受大文件概念应当具备一定的前提,在前提不具备的情况下使用大文件概念.就会给我国的档案学理论研究和档案工作实践造成负面影响.鉴于我国目前并不具备使用大文件概念的前提,因而得出大文件观是当代中国档案学的必然选择这一结论还为时尚早.     

基于Big6的信息素养在线课程设计与实现

根据信息素养内涵的基本内容,借助Big6教学模式,将信息素养在线课程的教学过程设计为一个主体类Big6教学过程和若干个分支Big6教学过程,并采用基于Petri网的建模方法对系统进行建模,实现基于Big6和Petri网的信息素养在线课程。并通过基于实际教学的实验对比,评价该系统在信息素养教学过程中的作用。     

称谓名词前“大”和“小”不对称问题的考察

“大”和“小”与数量范畴关系密切,用于区别量的大小。称谓名词不需要进行量的区别,却可以受“大／小”修饰限制。称谓名词前的“大”和“小”分别几种使用情况。“大”和“小”常体现出不对称现象,有多种原因共同决定了这些不对称现象。     

成都“大生活”作家的地方文化特征

新世纪以来,以车辐、乔瑜、罗清和、王跃、文迪、老樵、骆平、桑格格等为代表的小说作家,以描写成都人的＂大生活＂（乔瑜语）来展示成都故事,形成了一个带有鲜明地方文化特色的作家群体。他们对成都本土文化有本能的崇尚意识和自觉的理性透视精神,传达出特别鲜明的婉约阴柔、飘逸旷达的＂蜀水文化＂特征。成都人的生存本相都能从他们的笔端勾勒出明晰的具备了地域文化风情的生存图景,可以说是一幅成都市民生活的＂清明上河图＂。     

Mechanical power output in rowing should not be determined from oar forces and oar motion alone

Mechanical power output is a key performance-determining variable in many cyclic sports. In rowing, instantaneous power output is commonly determined as the dot product of handle force moment and oar angular velocity. The aim of this study was to show that this commonly used proxy is theoretically flawed and to provide an indication of the magnitude of the error. To obtain a consistent dataset, simulations were performed using a previously proposed forward dynamical model. Inputs were previously recorded rower kinematics and horizontal oar angle, at 20 and 32 strokes?min^?1. From simulation outputs, true power output and power output according to the common proxy were calculated. The error when using the common proxy was quantified as the difference between the average power output according to the proxy and the true average power output (P?_residual), and as the ratio of this difference to the true average power output (ratio_res./rower). At stroke rate 20, P?_residual was 27.4 W and ratio_res./rower was 0.143; at stroke rate 32, P?_residual was 44.3 W and ratio_res./rower was 0.142. Power output in rowing appears to be underestimated when calculated according to the common proxy. Simulations suggest this error to be at least 10% of the true power output.     

Responding to Big Data in the Art Education Classroom: Affordances and Problematics

The article raises questions about the use in art education classrooms of social networking sites like Facebook and image sharing sites like YouTube that rely upon the ability of Big Data to aggregate large amounts of data, including data on students. The article also offers suggestions for the responsible use of these sites. Many youth are using these sites as creative platforms and, taking their lead, the author describes his own use of YouTube as a creative tool in his pre‐service classroom. The author argues that most art educational literature that relies upon Big Data sites consider only the affordances and not the problematics involved, specifically issues of privacy and having youth effectively working as unpaid labour for global corporations.
