In order to further enhance experimental innovation of the undergraduates, the "verification model" in laboratory courses should be changed urgently. How to improve and develop the undergraduate laboratory courses has become an important direction of the laboratory teaching mode for university teachers. The students are easier to observe and understand the nature and core of the experiment by changing the experimental conditions and dialectically viewing of experimental problems. This kind of "dialectical view" is a good developing trend. We will apply this kind of model to the experiment of preparation of ammonium ferrous sulfate and semi-quantitative analysis of iron (Ⅲ). The students can deeply discuss the differences in the experimental results by controlling the synthesis conditions. The different colored and sized of crystalline in turn can stimulate students' interest. Practice shows that this teaching model is conducive to promoting students' ability of independent inquiry learning, to cultivate their dialectical experimental thinking, thus to enhance students' practical and innovative ability, and to improve their comprehensive quality. This model can be extended to other experiments.
