数字化实验在沈阳市高中化学教学中应用的现状研究
发布时间：2018-08-21 13:24
【摘要】：化学是一门以实验为基础的学科,许多化学理论和规律都是从实验中总结出来的,化学实验在化学教育和教学中具有不可替代的地位。在实验中传统实验发挥着很大的作用,但随着教育的不断改革,传统实验在实验现象、实验精确度等方面都存在一定的局限性。2010年《国家中长期教育改革和发展规划纲要(2010--2020)》把教育信息化纳入国家信息化发展整体战略,超前部署教育信息网络。为了将信息化与学科教学进行一定程度的融合,化学教学中融入数字化实验为我们找到了信息技术与理科教学融合的创新点。数字化实验以其多种类的传感器、多方式的数据采集器、多样化的操作平台以及强大的数据及图象处理系统,实现了实验手段的数字化、测量呈现实时化、现象规律可视化、操作测量简单化,在真实实验的基础上实现了信息技术与化学实验教学的完美融合。解决了传统实验中重定性轻定量的特点,定量却无法体现过程的现状,在延续传统实验的基础上不断创新、不断超越传统实验。数字化实验的引入有助于教师对于实验教学的完善与创新,也有助于教育信息化在教育改革中的推行。本文选择数字化实验在沈阳市高中化学教学中的应用现状作为研究课题,首先调查了沈阳市高中化学教学中教师对于数字化实验的应用情况及数字化实验应用中存在的问题,研究发现:沈阳市引入数字化化学实验设备较晚,现有数字化实验仪器的学校较少,数字化实验设备尚不能满足教师对于数字化实验的需求,在日常实验中应用数字化实验的教师较少,多数教师对于数字化实验的应用存在“应用难”、“应用繁”、“应用少”的问题。并立足于改进现状提出了培训的建议,为了能够帮助教师使用数字化实验设计了数字化实验的教学设计。对于沈阳市更好地利用数字化实验资源,以及教师更好地开展数字化实验提出了建议,同时可供其他地区借鉴。本文采用文献研究法、调查研究法等研究方法。
[Abstract]:Chemistry is a subject based on experiment. Many chemical theories and laws are summed up from experiments. Chemistry experiment plays an irreplaceable role in chemistry education and teaching. Traditional experiments play a very important role in experiments, but with the continuous reform of education, traditional experiments are in the experimental phenomenon. The National medium and long term Education Reform and Development Program (2010--2020) in 2010 put education informatization into the overall strategy of national informatization development, and advanced the deployment of educational information network. In order to integrate information technology and subject teaching to a certain extent, the digital experiment in chemistry teaching has found the innovation point of the fusion of information technology and science teaching. Digital experiment has realized the digitization of experimental means with its many kinds of sensors, multi-mode data collector, diversified operating platform and powerful data and image processing system. The operation measurement is simple and the information technology and chemistry experiment teaching are integrated perfectly on the basis of real experiment. It solves the characteristics of the traditional experiment, which emphasizes the quality and not the quantity, but it can not reflect the present situation of the process, and innovates constantly on the basis of the continuation of the traditional experiment, constantly surpassing the traditional experiment. The introduction of digital experiment helps teachers to improve and innovate the experimental teaching, and also helps to carry out the education information in the educational reform. In this paper, the current application of digital experiment in high school chemistry teaching in Shenyang is selected as the research topic. Firstly, the application of digital experiment and the problems existing in the application of digital experiment are investigated in high school chemistry teaching in Shenyang. It is found that the introduction of digital chemical experiment equipment in Shenyang is late, and there are fewer schools of digital experimental instruments, and the digital experimental equipment can not meet the needs of teachers for digital experiments. Few teachers apply digital experiment in daily experiment, most teachers have the problems of "application difficulty", "application complexity" and "little application" for the application of digital experiment. In order to help teachers design the teaching design of digital experiment, this paper puts forward some suggestions of training based on the improvement of the present situation. Some suggestions are put forward for Shenyang to make better use of digital experimental resources and teachers to carry out digitized experiments, which can be used for reference by other regions at the same time. This article uses the literature research method, the investigation research method and so on research method.
