Both teachers and students benefit from an interactive classroom. The teacher receives valuable input about effectiveness, student interest, and comprehension, whereas student participation, active learning, and enjoyment of the class are enhanced. Cost and deployment have limited the use of existing audience response systems, allowing anonymous linking of teachers and students in the classroom. These limitations can be circumvented, however, by use of personal digital assistants (PDAs), which are cheaper and widely used by students. In this study, the authors equipped a summer histology class of 12 students with PDAs and wireless Bluetooth cards to allow access to a central server. Teachers displayed questions in multiple-choice format as a Web page on the server and students responded with their PDAs, a process referred to as polling. Responses were immediately compiled, analyzed, and displayed. End-of-class survey results indicated that students were enthusiastic about the polling tool. The surveys also provided technical feedback that will be valuable in streamlining future trials.
教师和学生都能从互动课堂中受益。教师可以获得有关教学效果、学生兴趣和理解能力的宝贵反馈，而学生的参与度、主动学习能力以及课堂体验也会得到提升。成本和部署问题限制了现有课堂反馈系统的使用，这些系统能让课堂上的教师和学生进行匿名连接。然而，通过使用个人数字助理（PDA），这些限制可以被克服，因为PDA价格更低且被学生广泛使用。在本研究中，作者为一个由12名学生组成的夏季组织学班级配备了PDA和无线蓝牙卡，以便访问中央服务器。教师在服务器上以网页形式展示选择题，学生用PDA进行回答，这个过程称为投票。回答会立即被汇总、分析并展示。课堂结束时的调查结果表明，学生对投票工具很感兴趣。这些调查还提供了技术反馈，这对简化未来的试验很有价值。
