Learning executive function skills by playing focused video games

The objective of the present study was to determine whether it is possible to design a video game that could help students improve their executive function skill of shifting between competing tasks and the conditions under which playing the game would lead to improvements on cognitive tests of shifting. College students played a custom video game, Alien Game, which required the executive function skill of shifting between competing tasks. When students played for 2 h over 4 sessions they developed significantly better performance on cognitive shifting tests compared to a control group that played a different game (d = 0.62), but not when they played for 1 h over 2 sessions. Students who played Alien Game at a high level of challenge (i.e., reaching a high level in the game) developed significantly better performance on cognitive shifting tests compared to controls when they played for 2 h (Experiment 1, d = 1.44), but not when they played for 1 h (Experiment 2). Experiment 3 replicated the results of Experiment 1 using an inactive control group, showing that playing Alien Game for 2 h resulted in significant improvements in shifting skills (d = 0.78). Results show the effectiveness of playing a custom-made game that focuses on a specific executive function skill for sufficient time at an appropriate level of challenge. Results support the specific transfer of general skills theory, in which practice of a cognitive skill in a game context transferred to performance on the same skill in a non-game context.

Placing wireless tablets in clinical settings for patient education

Objective

The authors explored the feasibility and possible benefit of tablet-based educational materials for patients in clinic waiting areas.

Methods

We distributed eight tablets preloaded with diagnosis-relevant information in two clinic waiting areas. Patients were surveyed about satisfaction, usability, and effects on learning. Technical issues were resolved.

Results

Thirty-seven of forty patients completed the survey. On average, the patients were satisfied in all categories.

Conclusions

Placing tablet-based educational materials in clinic waiting areas is relatively easy to implement. Patients using tablets reported satisfaction across three domains: usability, education, and satisfaction.     

任弼时与中华苏维埃第一次全国代表大会的召开

Joint rate control and scheduling for wireless uplink video streaming

INTRODUCTION Video streaming is becoming one of the major driving forces of next generation wireless networks. For the currently deployed cellular networks, the practical data rates are not enough to support full rate, high quality video applications. As a result, many research efforts have been devoted to adapting video content to reconcile the conflict between the high demand of video quality and the limited wireless communication resources among users. A large body of literature utiliz…     

电子学习与远程教育的实践、创新、未来——第6届“Learning Futures Festival”在线国际会议综述

2011年4月第6届＂Learning Futures Festival＂在线国际会议召开。会议采用英国、美国、澳大利亚三个时区国家接力的方式完成。与会专家学者特别关注开放教育资源及Web2.0背景下的教育创新。未来10年全球高等教育面临巨大的增长需求,开放教育资源运动的推进,将可能出现开放教育资源大学。开放共享理念逐步深入人心,Web2.0在教育和企业领域的广泛应用将改变人们的学习和工作环境,学习者和企业员工应当提升自我的数字素养技能以激发自身的创新潜能。我国远程教育面临资源可重用性较低和开放性不足等问题,在今后的发展中应借鉴发展中国家远程教育院校和企业学习的成功经验,加强教育资源开放共享的程度,整合电子学习技术在远程教育中的创新应用,以满足学习者个性化的学习需求。     

基于录像分析背景下的初中统计课堂教学提问研究

在课堂教学中,教师的提问是最重要的活动.对两节初中统计课的课堂录像进行实录和量化分析,结合教师课堂提问的类型与学生回答之间的联系,得出:在统计课堂教学中(1)教师提问的数量相对比较少,提示类和理解类的提问类型所占比例较高;(2)学生无答的情况较少,但在问题回答中,学生机械性回答占了较大的比例,教师创新性问题较少;(3)教师提问难度与学生回答水平有直接的关系;(4)教师应围绕统计的特点进行提问,使学生经历统计的全过程,有助于提高课堂教学的有效性.     

Project Cheddarfield: Supporting Co‐Curricular Themes Through Creative Use of Video Course‐Casting

This article chronicles the coordination and better integration of existing institutional resources to support cocurricular themes embedded in the provision of a large enrollment, video‐mediated undergraduate operations management (OM) course. The name Project Cheddarfield refers to a 2008 initiative in which two professors team‐taught an OM course to over 600 undergraduates on two different continents through the repeated rapid exchange of digital video between the United States and Singapore. Simultaneously infused in this core curricular delivery were themes of global awareness and study‐abroad, including the promotion of one particular opportunity that bridged the two campuses. This action research narrative spans over 5 years of related activity leading up to the initiative, as this project is best understood as a trajectory, or the evolving result of design adapting to unfolding realities.
