The Teaching Practice Of Micro-courses In Junior High School Mathematics Preparation

With the continuous development of information technology, the status of computer in classroom teaching, explore everywhere in combination with the effective education, teaching and information technology, the grass-roots first-line teachers are trying to use new model to meet the demand of students' learning, micro course arises at the historic moment. After years of development, the teachers of class is no longer strange, some Internet companies are also beginning to make micro class.With the depth using micro class, flip the classroom based on micro class mode also gradually popularized. But different disciplines, different grades, different classes, the teaching effects are also different. Controversy is due to the effect of differ in thousands ways, education has gradually. Based on the above situation, the author studies how to make good use of all kinds of micro course resources and organic combination of the classroom as mathematics preview link, play its role to the greatest extent, provide some hope to use the class teachers in their teaching and help.This article obtains from the junior middle school mathematics preview link, first about the present situation of junior high school students mathematics preview and classroom learning habits, mathematics teachers' attitude toward matheematics prepare to do the investigation and analysis, draw lessons from this kind of flip classroom teaching mode, lesson preparation by junior middle school mathematics teaching mode, the three-month teaching practice research, selected from the three classroom implementation case is analyzed. In this mode, use the micro video instead of the traditional knowledge infusion, micro class using micro video elements design, guide students independent learning and cooperative learning group new knowledge. After the phased implementation of the model, through comparison before and after student achievement, student interview survey forms such as effect evaluation.Through effective classroom implementation and research found that junior middle school mathematics micro lesson preview mode is conducive to improving the students' interest in maths study and to cultivate students' thinking, to improve the students' ability of auonomous learning, to cultivate students' ability of team work.But also found in the process of practice, at present the school's information technology conditions,and the teachers' information technology literacy remains to be further cultivate and improve, like micro lesson preview mode turn classroom still difficult to spread in our country.
