The Application Of Handheld Technology In High School Complex Chemistry Experiment And The Research On Teaching

Handheld technology ,as a new tool of experiments with a combination of chemical experiment, has greatly enriched the study of chemical experiments and expanded the scope of the study of chemical experiments, thus bring the new changes for chemical experiments in the information age. This paper studies in the literature in-depth study based on handheld technology at home and abroad experimental research, found that current research relating to the issue of a simple chemical test, a single experimental research methods, too much duplication of effort, there is no practical technology to play a hand-held chemical experiments in the design and teaching applications, so this article will focus on the chemical perspective the complexity of experimental research.Given the available information is not the chemical complexity of the concept of the experiment described in this paper, first of all learn from the complexity of the relevant scientific research results, from the constituent elements of the experiment and experimental aspects of classification, such as the complexity of chemical experiments carried out to define relatively complete, and then from the chemical complexity of the experimental design of the hand-held technology development and application of two aspects were studied.In this paper, the use of handheld technology design complexity of the four chemical experiments: the determination of the chemical reaction rate, liquor in the determination of methanol, sodium carbonate and sodium bicarbonate series exploring quantitative experiments, vitamin C effervescent tablets integrated into the experiment, the author through research think that handheld technology is a powerful tool for developing complex chemical experiment .It can be turned into the complex for simple, intuitive variable abstraction to change static to dynamic, as a quantitative change for the chemical complexity of the experimental problems explored a a new way.Handheld-based technologies for the study of the chemical complexity of the experiment in teaching the specific circumstances of the application, the paper selected for the 60 normal subjects were undergraduate students to the complexity of water quality analysis as carriers of chemical experiments carried out empirical research results show that the students hand-held technology welcomed and endorsed the handheld technology in the chemical complexity of the application of the value of the experiment.The author in the study also found that the stability of hand-held technology and equipment and accuracy of test results is the impact of two important factors, so in order to further promote the chemical complexity of the experimental application of handheld technology and teaching, it is necessary to clear the technical obstacles.Literature study, experimental method, questionnaire, interviews and other research methods are adopted in the full text.
