The Knowledge Of Relevant Physical Structure Is Contrasted And Analysed In The Chemical Curriculum Standard Of High School

The middle school chemistry curriculum reform is the important constituent which our country elementary education curriculum reforms. The design reforms which based on this chemistry curriculum, chemistry curriculum structure has had the tremendous change. The middle school chemistry knowledge adopts "the module" the design, which stage regardless of in the middle school chemistry, all has the physical structure knowledge content the existence, need to be re-understanding;Moreover, in chemistry new curriculum standard, material structure knowledge itself has also had the tremendous change, to some knowledge requests compared to before enhanced, to some knowledge requests compared to before has reduces, but also increased many new knowledge;For example: Increased "the cheir molecule", "and so on the electronic principle" the knowledge and so on. The matter structural theory always is chemistry discipline important elementary knowledge, the content quite is abstract, is the middle school chemistry study key point, the difficulty;The physical structure knowledge has to other chemistry knowledge studies instructs and commands the function, its status is extremely important. Therefore, it is necessary to carry on the system analysis to this part of knowledge.Modern teaching theory development, emphasis study individual in teaching activity subjective initiative, emphasis teaching openness, difference and development. In the material structure classroom instruction also should manifest the basic idea which the new curriculum reforms, realizes the scientific accomplishment enhancement "three transformations", must more pay attention to student's in teaching activity main body status and the function, enhances the teaching the validity. Therefore, in the physical structure teaching, constructs the construction principle and "the advance organizer" the strategy took the basic teaching rationale, at the beginning of the attention, the high school matter structure knowledge teaching links up;The control physical structure knowledge content deep breadth, processes the good physical structure knowledge compulsory module with to take as an elective the module the relations;At the same time, the establishment advantage, overcomes the physical structure knowledge abstractly, is difficult to understand the study difficulty which brings to the student;In teaching reasonable utilization "advance organizer" teaching strategy.Through use of a variety of teaching methods and means to effectively implement the structure of knowledge classroom physical for students in middle school learning physical on the structure and nature of the theoretical basis of atomic structure, periodic law of elements, the chemical bond between effort and elements related knowledge;In the minds of students also develop a micro-structure inferred from the nature of macroeconomic concepts, formedfrom the intrinsic nature of things to proceed with the idea of detecting external appearance, and to allow students to develop things from the lessons of interrelated, and from the new law, the ability to forecast. This not only can move to other disciplines of study, the more students lay a foundation for future research. To foster a scientific accomplishment with the citizens, and to train future in the chemical disciplines further studies professionals, is of great significance and value.
