面向制造的板级电子电路产品多信息模型研究

Most electronics products use PCB to carry electronic circuits. This paper classifies information contained in PCB-based electronic circuits into several models: geometry model, physics model, performance model and function model. Based on this classification, a multi-information model of product is established. A composite model of product is also created based on object-orientation and characteristics of the product. The model includes a 3D geometry model, a physics model with integrated information that can be divided into microscopic and macroscopic information, a generalized performance model and a function model that are from top to bottom. Finally, a multi-unit analysis is briefly discussed.     

信仰在科学中的地位与功能

物理学的发展自始至终深受着信仰的影响,即它不仅为物理学的创立提供了一种形而上学的约定和先验的理论框架,而且尤为重要的是它还为物理学的创造提供了一种强大的精神动力。揭示信仰在物理学及其他自然科学学科中的地位与功能,能给予人们深刻的启示。     

Video diaries: a tool to investigate sustainability-related learning in threshold spaces

This paper takes as a case study an undergraduate field class from a UK university to rural Uganda. It describes and evaluates the use of video diaries as a tool for investigating the process of transformative learning in the context of education for sustainability. The applicability of threshold concept theory to this learning is investigated. Results show the video diary technique to be much more successful in capturing the development of student learning than written diaries. Despite some practical difficulties, rich data were generated. Analysis demonstrated that learning met three of the five criteria for threshold concepts: the learning was transformative, integrative and troublesome. Further research could test whether the learning in this case study met the threshold concept criterion of irreversibility. Further elaboration of the theoretical relationship between threshold concepts, transformative learning and education for sustainability is also needed. It is concluded that the video diary method is potentially transferable to other educational research contexts and may be particularly suitable for researching learning in threshold spaces.     

返璞归真：让物理感觉成为教学的内在追求

如何沟通学生的科学世界与生活世界,提高学生的科学素养,是目前物理教学改革的重要理论命题和实践难题。而以往被人们忽视的学生＂物理感觉＂,恰恰是连接这两个世界的重要桥梁。鉴于此,我们有必要厘定物理感觉的内涵、分析物理感觉的类型,并藉此提出优化物理教学的策略。     

师范毕业生教育游戏认知情况调研

教育游戏的应用与发展很大程度上依赖一线教师对教育游戏的理解,因此了解即将成为一线教师的师范毕业生对教育游戏的认知状况与期望有助于把握教育游戏应用的现状以及未来的发展趋向．该文通过对南京晓庄学院302名不同专业的师范毕业生的抽样调查,分析讨论了师范毕业生对教育游戏的概念认知、功能认知以及期望．通过调查发现：师范毕业生对教育游戏的概念认知程度偏低,不同专业的师范毕业生对教育游戏的概念认知情况存在较大差异;师范毕业生对教育游戏的教育功能持肯定态度;师范毕业生对教育游戏的课堂教学应用持怀疑态度;师范毕业生对于一款“好”教育游戏产品的期望主要表现在教育游戏的趣味性和教育性方面．

University physics students’ ideas of thermal radiation expressed in open laboratory activities using infrared cameras

Background: University physics students were engaged in open-ended thermodynamics laboratory activities with a focus on understanding a chosen phenomenon or the principle of laboratory apparatus, such as thermal radiation and a heat pump. Students had access to handheld infrared (IR) cameras for their investigations.

Purpose: The purpose of the research was to explore students’ interactions with reformed thermodynamics laboratory activities. It was guided by the research question: How do university physics students make use of IR cameras in open-ended investigation of thermal radiation as a phenomenon?

Sample: The study was conducted with a class of first-year university physics students in Sweden. The interaction with the activities of four of the students was selected for analysis. The four students are males.

Design and methods: We used a qualitative, interpretive approach to the study of students’ interaction. The primary means of data collection was video recording of students’ work with the laboratory activities and their subsequent presentations. The analysis focused on how IR cameras helped students notice phenomena relating to thermal radiation, with comparison to previous research on students’ conceptions of thermal radiation.

Results: When using the IR camera, students attended to the reflection of thermal radiation on shiny surfaces, such as polished metals, windows or a whiteboard and emissive properties of surfaces of different types. In this way, they went beyond using the technology as a temperature probe. Students were able to discuss merits and shortcomings of IR cameras in comparison with digital thermometers.

Conclusions: With the help of IR cameras, university physics students attend to thermal phenomena that would otherwise easily go unnoticed.     

论儿童精神的诗性逻辑

儿童的逻辑不同于成人世界中的概念性逻辑。儿童的逻辑汇入了并充盈着鲜明而强烈的感性色彩和浪漫主义审美意蕴的诗性精神。诗性的逻辑是展现儿童精神之特质的基本表达形式,也为人类理性精神插上了想像的翅膀。
