How to build a junior high school math efficient classroom under the new curriculumstandardsAbstract: With the deepening of the reform of mathematics teaching, effective teaching basic concept has been widely recognized and mathematics teachers effective implement positive change and update the concept of education as a first-line teachers, improve their professional quality, optimizing the teaching strategies to enhance the junior high school the effectiveness of the teaching of mathematics, has become the key to deepening the curriculum reform and fundamental requirement.Keywords: effective teaching junior high school mathematics efficient classroom Since the implementation of the new curriculum, “Lightening efficiency has been we explore the research topic. Promote the new curriculum reform at the same time there have been some misunderstanding, such as from the traditional teaching of”speak in the end, to theso-called new lesson change “a question in the end”from the past, taking the leading role of teachers toward younger age language games we should actively reflect on the past and present mathematics teaching quickly understand the new math curriculum ideas, seize the classroom teaching this the main front of the classroom 45 minutes to the quality and improve the effectiveness of mathematics teaching.A dilute form of the premise of effective teaching mathematics classroom Classroom teaching is often a mere formality, since the New Curriculum enacted, the efficiency is not high, there has been the phenomenon of going through the motions. Teachers this misunderstanding is a good lesson: create situations to introduce students to discuss cooperative learning, the use of multimedia essential aspects of teaching, teachers in the teaching of the design a one-sided pursuit of cooperative learning in the form, as long as there is a problem, regardless of difficulty, whether the value in the group discussion some time of discussion no guarantee, often students did not enter the discussion at the requestof the teacher hastily concluded, after a lively discussion, the students can understand to understand it? clear lesson learning tasks? Such cooperative learning in the form and no substance, teachers should be based on different classroom teaching methods, teaching objectives and course content design problem situation carefully designed teaching. example, many of the junior high school math knowledge content of the real life background, like “negative, axis, absolute value equations application”can introduction of appropriate living situations, explore the exchange, but there are also a lot of knowledge of content, such as the “algebraic algorithms, formulas, theorems” straight to the point and went straight to the theme, such as direct access to the core of the problem, saving time resources, thereby improving the efficiency of classroom teaching .Second, the dialogue on an equal footing is the key to effective teaching of mathematics classroom Classroom teaching reform involves a wide range of issues, how to construct the educational environment, in line with the new curriculum ideas between teachers and studentsto create a teacher-student teaching “warm community” is one of the important issues, teachers and students to build a lively and full of personality equality dialogue, mutual respect and a classroom situation, it will stimulate students’sense of ownership on the will not easily Bangsha the awkward whimsy inconsistent with their teaching ideas.For example, the polygon interior angles of this lesson, teachers guide the students connected diagonal starting from the vertices of the polygon, the angles of a n-gon and (n-2 ·180 °n-gon into n-2 triangles obtained However, there is a student whim, he is not starting from the vertex point of view but from the edge of any arbitrary connected to other vertices divided into triangles, teachers and his enthusiasm for dialogue, encourage students reasoning to find out this way to make a (n- interior angles of a triangle and after n-gon interior angle of 180 degrees, remove the excess of 180 degrees, results, or (n-2 ·180 degrees. teachers teaching behavior not only makes the student was encouraged, also stimulated the enthusiasm of the other students in the inquiry.posted in the free papers Download Center three students to participate in effective teaching of mathematics classroom The basic starting point of the new curriculum is to promote a comprehensive, harmonious and sustainable development of flexible use of teaching methods in the teaching, the creation of the space-time students to participate in the inquiry, so that students’active participation, active inquiry, allowing students to think, let the students to think, to allow students to enable students expressed representation, to enable students to allow students hands-on do-it-yourself, allow students to derive conclusions should allow students to derive their own teachers just to participate in the learning activities of students as “collaborators”, the creation of various kinds of opportunities to help the students to discover and explore the mysteries of knowledge, students self-learning, self-development in the process of mathematical activities.Such as making the meaning of “probability”teaching, teachers ask questions: randomly tossing a coin, “face up” or “negative upward, but it is easy to guesstwo random events can not be determined in advance the possibility that the same half of each. then, all this intuition is correct it? then, the teachers arranged the test tasks, guide students hands-on practice, cooperative inquiry. Fill teaching materials on the table, teachers groups measured data of each group of data records on the blackboard, the students in the class statistical data, and summarize the exchanges. Relatively small number of trials, it is possible to obtain the “face-up different from the frequency with conjecture, teachers should inspire students to analyze the causes of the differences, to enable students to recognize the frequency of each randomized trials with uncertainty, and at the same time found that the frequency of random events occur with regularity like this change listen secondary school learning, “learning by doing”, “attempt to secondary school”, “experience secondary schools the opportunity for students to create.Moderate evaluation is a catalyst for effective teaching of mathematics classroom Teachers in the teaching process to student development-oriented, timely,moderate, pluralistic evaluation of students. To really play evaluation to promote the development of students, teachers have to be good at discovering in the classroom and make timely evaluation, but also to prevent the evaluation of extreme tendencies in the curriculum standard process I believe that the evaluation should be objective and impartial principle on the encourage-based learning activities for students, teachers must correctly handle the students’ mistakes, not abuse recognition of evaluation, the error can not muddle through for students must Elicit solving ideas, and then to make the appropriate evaluation error but implies the idea of ​​innovative thinking, encouragement, and then pointed out, so to encourage students to continue to progress, to stimulate students’ enthusiasm for learning and innovation spark.In short, the effective mathematics classroom teaching to focus on the development of every student fundamental, teachers have to build a platform, pave the way, gave the students need more time in the classroom teaching, by allowing students to think more, More toexplore, more to say and do, so that teaching to meet students’ individual differences, to achieve high quality and high efficiency of classroom teaching, our students will learn to be more confident, more exciting life.References 1, Fu before dawn mathematics teaching new ideas.
