水环境化学作用CAI课件的制作

计算机辅助教学CAI（Computer-Assisted Instruction)是现代计算机技术发展与教学内容相结合的产物。本文主要介绍了计算机辅助教学CAI课件的优点和特点。详细说明了水环境化学作用CAI课件的制作过程，探讨了具体制作一个CAI课件的流程。     

多媒体CAI课件常用素材文件的格式

在制作多媒体CAI课件中,常常会用到一些文件格式,如图象文件格式、声音文件格式及动态视频、动画文件格式.本文就是针对以上格式的性能、特点、使用、范围分别加以阐释.     

《生药学》CAI软件的应用研究

探索了《生药学》辅助教学软件的制作,阐述了该软件制作方法,进行资料收集与整理制作,软件编制,描述了其应用特点,操作主界面简洁,按照《生药学》教学特点,编制了笔划、药用部位、科名、拉丁药名四种查询方法,不但在课堂教学中应用效果佳,而且还用于实验教学.进行CAI系统设计,动态组织教学内容,调整教学方法,加强了老师和学生之间的交互能力,实现了以学生为主体课程网络教学辅助方式.图2,参5.     

Computer-based training for food services workers at a hospital

INTRODUCTION: Interactive computer-based safety instruction (CBI) was given to 73 workers in the food services department of an urban hospital. RESULTS: Post-test accuracy (95%) improved significantly (p < or = 0.0001) from the pre-test (74.5 %), d = 1.09. Generalization was confirmed by increased accuracy in answering questions, posed on-the-job, that required application of knowledge to the work setting (from 46% to 79%; p < 0.0001). Problematic kitchen conditions such as puddles increased slightly after training, but adjustment for increasing production/workload revealed an overall post-training decline in problems from 0.58 to 0.32 (p = 0.0001, d = 0.89). Work practice improvement was seen in 79% of workers (p < 0.0001, d = 1.00). Effect sizes (d) of knowledge, location, and work practice improvements are large and demonstrate that the benefits of CBI extend to the workplace floor. Further, the decrease between knowledge and behavior change (d = 0.09-0.2) is less than reported following other forms of training.
