Research on Open Experimental Teaching in Different Phases and Layers in Analytical Chemistry

Open experimental teaching is an effective method of innovation of analytical chemistry experiment which recognized by most university. But excessive opening and neglectful grounding made students grounding unstably, operation unskillfully and teaching effect unreached. We combine confirmatory experiment with open experiment. opening experimental teaching in different phases and layers. In this method, we could cultivate students' well-grounding and the capability of solving practical problems and scientific research. we brought forward the projects of open experimental teaching in different phases and layers.
