经典电路实验翻转课堂教学模式的设计

以经典电路实验课程《RC过渡电路性能的验证》为例，给出了其翻转课堂教学模式的设计。课前以网络平台为载体推送学习资料，课上测试合格的学生才被允许进行实验，实验前给出启发式问题，实验后组织学生分组讨论，教师可针对学生的学习情况进行个性化指导，实现了自主学习+沉浸性操作+个性化教育的学习模式。教学实践情况表明，翻转课堂有效解决了实验学时不足的难题，效果良好。

Hyperwelcome

Web page annotation and adaptive navigation support are two active, but independent research directions focused on the same goal: expanding the functionality of the Web as a hypertext system. The goal of the AnnotatEd system presented in this paper has been to integrate annotation and adaptive navigation support into a single value-added service where the components can reinforce each other and create new unique attributes. This paper describes the implementation of AnnotatEd from early prototypes to the current version, which has been explored in several contexts. We summarize some lessons we learned during the development process and which defined the current functionality of the system. We also present the results of several classroom studies of the system. These results demonstrate the importance of the browsing-based information access supported by AnnotatEd and the value of both the annotation and navigation support functionalities offered by the system.     

The acceptance of Tablet-PCs in classroom instruction: The teachers’ perspectives

Limited research has been conducted on the integration of Tablet-PCs in classroom instruction. This paper reports a qualitative study which investigates the acceptance of Tablet-PCs, seen as technological innovation, amongst teachers. The research approach intends to complement research on the acceptance of technology through a more detailed qualitative examination. Semi-structured interviews were conducted with 18 teachers during a pilot project introducing Tablet-PCs to classroom instruction at three different schools. The findings indicate diversity in the attitude of teachers towards the technology, but also with regards to the performance expectancy and the facilitating conditions.     

Gravitating towards mobile phone (GoToMP) during lecture periods by students: Why are they using it? and how can it be measured?

With the growing amount of research on the use of technology, especially the mobile phones, the paucity of research in the area of mobile phone use that focus on the reasons why students use their mobile phones during lecture periods is somewhat surprising. Findings from the previous studies have documented that students continue to use their mobile phones during lecture periods even in classes where its use is banned. Thus, the motives that determine students' continued intention to use their mobile phones during lecture periods becomes an important issue that deserves urgent attention from researchers and education policymakers. In the present investigation, we tried to fill this gap by examining the determinants of students' continuance use of mobile phones during lecture periods. To achieve this, three stages of instrument development (item generation, scale development, and instrument testing) were undertaken through two studies. The results of the exploratory and confirmatory factor analysis confirmed the existence of six dimensions in the proposed measurement instrument (which we referred to as gravitating towards mobile phone (GoToMP)); the dimensions are boredom, class-related use, social connection, emergency, addiction, and perceived behavioral control. The combined findings from the two studies reported here provide initial evidence that GoToMP exhibits excellent psychometric properties and can be used in future empirical research on mobile phone use behaviors of students.     

Integer programming methods for large-scale practical classroom assignment problems

In this paper we present an integer programming method for solving the Classroom Assignment Problem in University Course Timetabling. We introduce a novel formulation of the problem which generalises existing models and maintains tractability even for large instances. The model is validated through computational results based on our experiences at the University of Auckland, and on instances from the 2007 International Timetabling Competition. We also expand upon existing results into the computational difficulty of room assignment problems.     

Implementing flipped classroom using digital media: A comparison of two demographically different groups perceptions

Flipped classroom is a relatively new model in education that primarily focuses on learner-centered instructions. In other words, the model allows both management and teachers to build a more active and dynamic learning environment on the campus. The current paper tries to document the implementation of the flipped classroom model in two big data courses. Here, the course contents have been curated from a couple of websites with different contents including videos and short books as well as reports. The mixed-method approach was applied while analyzing the student perceptions in demographically two different groups. It was found that students of both groups responded positively to the flipped classroom, with each focusing on their specific goals. Consequently, the first group focused on the academic achievement whereas the second group with managerial jobs focused on solving problems in their workplaces. Students of both groups, although preferred TED talks and documentaries, they were opposed to university-like videos and O'Reilly short books and reports. Meanwhile, the use of English language contents turned out to be both a challenge and an opportunity for students.

Classroom ventilation and indoor air quality—results from the FRESH intervention study

Inadequate ventilation of classrooms may lead to increased concentrations of pollutants generated indoors in schools. The FRESH study, on the effects of increased classroom ventilation on indoor air quality, was performed in 18 naturally ventilated classrooms of 17 primary schools in the Netherlands during the heating seasons of 2010–2012. In 12 classrooms, ventilation was increased to targeted CO₂ concentrations of 800 or 1200 ppm, using a temporary CO₂ controlled mechanical ventilation system. Six classrooms were included as controls. In each classroom, data on endotoxin, β(1,3)‐glucans, and particles with diameters of <10 μm (PM₁₀) and <2.5 μm (PM_2.5) and nitrogen dioxide (NO₂) were collected during three consecutive weeks. Associations between the intervention and these measured indoor air pollution levels were assessed using mixed models, with random classroom effects. The intervention lowered endotoxin and β(1,3)‐glucan levels and PM₁₀ concentrations significantly. PM₁₀ for instance was reduced by 25 μg/m³ (95% confidence interval 13–38 μg/m³) from 54 μg/m³ at maximum ventilation rate. No significant differences were found between the two ventilation settings. Concentrations of PM_2.5 and NO₂ were not affected by the intervention. Our results provide evidence that increasing classroom ventilation is effective in decreasing the concentrations of some indoor‐generated pollutants.
