1Improve the effectiveness of the strategy Middle School Chemistry ReviewAbstract: how to improve the effectiveness of third year chemistry review, this paper from the refinements of “Outlines”, grasp the direction, solid double-base, build networks, extending to expand, enhance skills and attention to experiment, improve skills, standardized training, literacy training, with practice, to broaden our horizons six areas to be addressed. Keywords: new curriculum, third year chemistry, review, effectiveness Middle School Chemistry Review is a systematic project, constructed under the new curriculum and efficient review of the classroom so that students in the review of “knowledge, thinking ability,” have been developed, that every third year to pursue the highest goal of teachers. Here I talk about in the review Several strategies and communication with everyone. First, refinements of “Outlines”, grasp the direction is the basis for teaching, “ is the basis of 2college entrance examination is the basis for reviewing and preparing for college entrance. clear the examination syllabus and the ability of the specific requirements of:” Chemistry Test designed to test candidates on the basis of high school chemistry knowledge and basic skills to master the situation and should have the observation, experimental ability, thinking ability and learning ability, the initial questions the candidates should also apply the test of chemical knowledge, observation, analysis of life and production and society in various capacities related to chemical problems. “Middle School pressing, weight, point of view of the complicated chemical characteristics of subject knowledge, teachers often by induction, combing knowledge points, break points, the analysis of a typical exercise, the teacher is talking detailed, thorough analysis, however, instead of the student teachers in the construction of knowledge framework. This review of the traditional method of indoctrination, the students and the rote learning in a passive acceptance, lack of vitality of the classroom, students learn initiative and enthusiasm can not be effectively mobilized, so that teaching does not help “the students learned self-3development initiative to build the chemical basis of knowledge and basic skills.” So seriously study the “Outlines”, grasp the entrance of the “Pulse” is the premise of improving the efficiency review. Second, solid double-base, building networks Implementation of new teaching materials teaching modules, focused on improving the scientific literacy of citizens, focusing on the process of scientific inquiry and scientific research methods, and enhance innovation and practical ability, that softened in the preparation of system knowledge. The new curriculum is to review the important task of teachers Under the guidance of, and guide students to the knowledge of the various parts of the corresponding intrinsic connection to summarize their integration, will be scattered, isolated knowledge points strung line, form networks of knowledge into the fabric of the students to form a complete system knowledge. it is stored in the mind, like library books through the code can be “handy”, flexible application, reducing the memory burden on students and improve the efficiency and ability to solve problems in order to achieve knowledge transfer. 4our specific practices are: 1. The use of case study, solid foundation Capacity for knowledge, but crushing the review compared the contents of elements and their compounds, such as knowledge, knowledge of the point of a unit designed to fill in the blank forms in the form of the text before class so that students complete on their own case study. Class teacher is not a simple proof in order to study the case, you can take to enable students to answer questions one by one, teachers ask questions cause students to think discussions, quizzes and other forms of small tests, which not only improve the effective participation of students in the classroom to help students sort out the effective knowledge, while clicking through the main points of teachers, answering questions, expanding the depth and breadth of knowledge points, to reinforce the foundation has played a very good role. 2. Seize the trunk, build networks Nitrogen and its compounds, such as knowledge of the review can be to change the valence of nitrogen N2 NH3 NO NO2 HNO3 NaNO3 main line to start combing the knowledge to landscape the 5redox chain. While the use of material structure theory of association online periodic law points (representing matter) according to the structure Properties preparation, use, presence, and inspection begin again, the relationship between these substances into the connection between the webs, so that knowledge of systematic, organized manner. and then review the nature of ammonia can be The molecular structure of the first memories of
