| In the new round of proposed basic education ,China refer to its specific goals: "Curriculum change the tendency to be too focused on knowledge, emphasizing a proactive attitude to obtain the basic knowledge and basic skills course at the same time as learning to learn and the process of forming the correct values";"We must change the mechanical, stiff and human lacking teaching methods in order to develop the students'abilities of taking part in actions actively, discovering happily, operating diligently, collecting and handing information, analyzing and solving problems, exchanging and cooperating."Combining the situation of the existing high school chemistry teaching, building and practising a practical and new curriculum conforms to the concept teaching mode——the Model of"coming situation-discovering-constructing", is not only very necessary, but also very meaningful.The Model of"coming situation-discovering-constructing",is on the basis of students'owned knowledge and experience to guide students into the related teaching environment which enable students to use independently explore ways to establish that the knowledge structure and personality structure, and ultimately psychological structure of a self-teaching model. The "coming situation" in the model refers primarily to the existence and application of knowledge in which the whole picture, background or environment; The "discovering" refers to the classroom chemistry textbook knowledge rediscovery and access; The "constructing" refers to processing and integrating the discovered knowledge; restructuring and expansion of existing cognitive structures and knowledge systems; constructing their own knowledge and experience of learners.The dynamics and opportunity of the model are the environment with which students are familiar; The ways and means of the model are through discovering knowledge by students independently; The purpose of the mode is to build their own knowledge and experience and to allow students to experience the process of knowledge formation. The model uses in the process, always student-centered and focuses on the students'self-control mentality, structures and capacities to promote student awareness of the structure formation. This model is carried out in research of scenes teaching, the discovery method of learning, and constructive learning and the status of development on the basis of educational theories, such as the lifelong education theory, the main theoretical education, emotional education and so on, and the psychological theories, such as Gestalt theory, cognitive theory, constructivism theory and so on. It integrates scenes... |
