Abstract: Two thirds of chemical equations are redox reations among all of the chemical equations. These kind of chemical equations are generally hard to balance just by observing, so it is the key and difficult point to balance the chemical equations of redox reation. In the middle and high schools’ chemical teaching materials, only some simple methods of matching balance are lectured.But it is very hard to deal with the specific problems by these methods. Therefore, I came up with the matching balance method of mark, obersavation, decision and balance. This method can be used to balance any chemical equations of redox reaction exactly and quickly.Abstract: Two thirds of chemical equations are redox reations among all of the chemical equations.

Abstract: Design performance technique course is a fundamental course in environmental art major, which is of practical and operational use. In face of the existing problems in traditional teaching, the author has worked out an on-line and off-line blended learning method based on the teaching concept of MOOC, committed to integrating optimal teaching resources with actual class experience so as to make the best of advantages and supplement the shortcomings, give full play to features of different teaching environments and set up a deep learning system of information reception, experience and internalization. In such manner.This paper analyzes the blended learning in design performance techniques course, The establishment of the course teaching mode mainly includes to perfected the learning resource library, the design of teaching activities and the construction of multivariate evaluation mechanism. Through continuous teaching practice and reflection, the teaching philosophy is reshaped and the teaching mode is mixed with a variety of teaching methods to stimulate students' interest to a greater degree,learning will turn to active learning and study efficiency will be promoted. At the same time, it is expected to provide reference for teaching workers.Abstract: Design performance technique course is a fundamental course in environmental art major, which is of practical and operational use.
