| Chemistry is an experimental subject. This is the characteristic of both chemistry discipline and chemistry teaching. The chemical experiment teaching plays an important role in the students’ scientific thinking, hands-on capacity and innovation. However, one reason of the time constraint in traditional chemical experimental teaching, students can not finish an experiment part in class which should be finished within two or three hours. So, they have no time thinking about it. On the other reason of the shortage of experimental fund and apparatus, it is impossible for every student to experience and practice each experiment.In order to guarantee the quality of experimental teaching, the following measures should be applied in chemistry teaching, such as, changing the traditional teaching mode, making use of the new teaching methods and advanced teaching facilities. Chemistry experimental teaching assisting with the computer simulation can embody the interactivity and help students understand and master the knowledge of chemistry experiments, and also can cultivate the students’ abilities of outsight, attention and logical thinking. It has been proved through practice that computer assisted instruction will become one of the important ways in the chemical experiment teaching.Therefore, the design and development of computer simulation experiment becomes an important research topic and also comes to be the urgent problem to solve in the subjects of physics and chemistry in high school experimental teaching. This dissertation with the combination of PEP students’ book of chemistry subject of ninth-grade (Volume One) develops the software of virtual experiments by analyzing the experiments of chemical preparation of oxygen, water electrolysis, hydrogen reduction of copper oxide and other five chemical experiments. On this basis, the paper is to strive to achieve virtual, practicality, flexibility, open and interactive features. And virtual and real experiment will be integrated, play to their strengths, learn from each other, forming a versatile education system in order to attract students to learn actively, and the other significance of this dissertation is to integrate the virtual experiment and real one, play their own advantages, and form a new multi-functional teaching system to appeal to more students to study enjoyably.The dissertation mainly includes the following parts:First, the application of computer technology in chemistry and chemical experiment situation has been summarized. The operation interface of Macromedia Flash and important concepts have been introduced as well as its advantages in exploring platform with intelligent simulation system. The junior middle school chemistry experiment types are classified, the teaching mode choice are discussed in a virtual environment, and the combination of virtual experimental teaching and blended learning theory.Second, the development of intelligent simulation techniques in chemistry experiment and its exploring platform has been described in classification. The dissertation designs a simulation system in chemistry experiment, makes the flash of experimental contents, design ideas and experimental process and it also introduces the details of the fracture of experimental material elements, interface structure and styles.Third, by using several cases of oxygen, water electrolysis, hydrogen reduction of copper oxide and other five chemical experiments, the combination of real experiment chemistry experiment teaching modes has been designed as examples. |
