| Probing into instruction is a kind of ideal teaching model of basic education curriculum and instruction in my country.In the innovation of new curriculum, probing into learning has become the basic component of teaching and learning in the new curriculum ,while Chemistry is on the basis of experiments,probing into and summarizing a lot of chemistry facts scientificly.So to construct probing into instruction model in chemistry classes under the new curriculum ideas is very significant actually.According to the characteristics of chemistry subject—experiments and scientific seeking - independence participation cooperation.The author constructed a probing into instruction model in chemistry classes by independent experimental probing,raised the procedure of the model, teaching principles and tactics,adopted group experimental seeking in class,independent seeking and discussing with others avoiding students "looking at " in teaching ,which is the innovation and improves the seeking efficiency ,students'positivity and participation .The author studied the model primarily by experiments.According to independent probing into experimental instruction model and strategy,The author taught chemistry in the experimental team in the Affiliated MiddleSchool of the National Defence Science and Technology University in Changsha,choosing the typical chapter: halogen in the chemistry teaching material in all-day senior middle school( the People'Education Publishing Company ,2003) as the experimental materials .The results of experiment ,after learning the chapter: halogen,showed that applying probing into experimental instruction model to Chemistry teaching is available, the students' Chemistry performance is not lower than that in traditional teaching model, the efficiency of tuition doesn't decrease; Meanwhile applying probing into experimental instruction model to Chemistry teaching can make students'positivity boost rapidly and the learning ability improve fast.
