一、利用手持技术阐释微观世界物质变化手持技术是利用传感器、数据采集器、计算机三者连接,对实验体系中某种(或某几种)物理参数进行实时测量,从而用于研究化学本质问题的实验装置。采用手持技术与多媒体技术相结合使微观过程宏观化,将内容抽象、教师难讲、学生难理解的问题,用所测得的实验数据来解释,增加了理论的可信性、现象的直观性,可以帮助学生进一步理解微观世界物质
First, the use of hand-held technology to explain the material changes in the microscopic world Hand-held technology is the use of sensors, data acquisition, computer connection between the three, the experimental system in one (or several) physical parameters in real-time measurement, which is used to study the chemical nature of the problem experimental device. Adopting the combination of hand-held technology and multimedia technology, the microscopic process is macroscopical, the content is abstracted, the teacher is hard to say and the student is hard to understand. The problem is solved by the experimental data measured, which increases the credibility of the theory and the intuition of the phenomenon , Can help students to further understand the micro-world material
