1High school chemistry experience and practices of the overall reviewThird year general chemistry is a systematic review of teaching project. After years of teaching practice, I deeply appreciate: in guiding the Entrance Exam, the teacher had been able to curricula, the examination shows based on books based on a careful analysis of the situation and the school calendar year Entrance Examination, and on this basis, conscientiously do a good job basis review - Review topics - simulation training and other review stage, will be able to receive a good review results to improve student performance chemicals. 1, according to the key link button book, pay close attention to double-base, building knowledge networks. A careful analysis of the grounds since 2002 Comprehensive College Entrance Examination, we can easily find the chemical examination questions closely follows the secondary school curriculum, follow the examination instructions, based on textbooks, attached great importance to the candidates basic knowledge and basic skills to examine and challenge the proportion of small, interdisciplinary Few comprehensive title. Thus, in recent 2years, university entrance, any solid footing, thinking flexibility, standard answer candidates can often achieve better results. This requires us to review teachers in the basic stage, make sure that they grasp the key link of this service, to enable students to clear learning objectives, guide the students to build a complete self-knowledge network, so that an orderly storage, flexible application, so that double-base teaching a real fall at all units. Specifically, we can start from the following aspects: 1, so that three research, to enable students to review specific targets. In each chapter before the review, teachers must be in-depth study materials, the backbone of this section a clear knowledge of what is the logical relationship between the knowledge points are; research考纲 clear what the college entrance examination test, test to what level, is to require understanding, or should understand and master, or require a skilled use; studies exam, college entrance examination is to examine such a clear trunk knowledge. And to the information explicitly told the students, so that students can review when you can do a pretty good idea of this chapter, a clear context. 32, focusing on the formation of knowledge to enable students to overcome the rote. Chemical knowledge broken, scattered, complex, multi-memory capacity large, a lot of students to review when Trying to adopt a rote approach, the results achieved little that end, teachers should change the previous conclusions re-light the process of teaching orientation, in the teaching of a knowledge of each point, teachers should be exposed as much as possible their own thought processes to reveal the knowledge and teaching focus on the formation process, the guide the students through the (specific) perception - (abstract) summary - (actual) applications of thinking to master the law of the process to discover the truth. Only in this way can we in the teaching process, to thinking of the students are trained not only to consolidate the foundation, and also enhance capacity. Such teaching can make students one by one knowledge point and orderly manner grafted into contact with the inner logic of knowledge chain, and thus rely on logical reasoning to master knowledge, is no longer alone to learn by rote. A lot of students felt Entrance Exam: a lot of knowledge of their own really down, but do not have 4access to the exam Shi Que. The reason, I think that is what we re conclusion, light process of teaching situation caused by stripping it from the source of knowledge and intelligence inherent connection, the students did not have become textbook knowledge in their own abilities and qualities, so it is impossible in the practical application of knowledge will be activated. 3, vertical and horizontal series, to enable students to build knowledge networks. Access to knowledge, if not perfect knowledge structure linking it, it is a kind of knowledge most will be forgotten. In the Entrance Exam to guide students to build their own knowledge networks, knowledge and context so that students can clear the trunk, so that an orderly storage, Entrance Exam is an important task to be accomplished. In this regard, my approach is: first to guide the students to the knowledge of unit for vertical trunk link to identify the intrinsic link between knowledge and, based on knowledge of the logical link between the outline units of knowledge network diagram, so that, through the unit Review, you can thin thick at school (a unit of 5knowledge is just a card), such as completion of a chapter ionization, may guide the students to reach the following chart: Elements of compounds that knowledge is an important part of high school chemistry, in the review element compounds of knowledge, it can guide the students bas
