A Study On The Development Of Experimental Teaching Ability Of Chemistry Students

The implementation of the new chemistry curriculum standard proposed higherrequirements to senior high school chemistry teachers. I Iowever, the experimentalteaching skill level chemistry teachers has become one of the key factors affecting themiddle school chemistry curriculum reform success. The student chemistry educationmajor of normal universities faced with the urgent problem about how to adapt to thenew curriculum reform in senior high school chemistry teaching requirements andteach skills training with higher levels of "research-typed teachers". Through theresearch on the current situation of experimental teaching ability of normal studentsreviewed chemistry, starting from the definition of chemical experiment teachingability, construct the evaluation index system of chemical experimental teachingability, on the basis of this, the normal students were investigated in different types ofchemical experiment teaching present situation, in order to understand the ability ofnormal school students in experiment teaching development, help the teachers andstudents the idea of "the connotation of chemical experimental teaching ability",provides the reference for the construction and reform of normal university students inthe chemistry curriculum, so as to provide guidance for the development of normaluniversity students ability of experiment teaching.This research mainly adopts the methods of observation (observation and videoobservation) and using the method of thinking aloud method，and interview method ofcombining design，based on the prior3chemistry experimental teaching problemsrelative to the typical tasks, respectively, salt purification experiment, neutralizationtitration experiments and the preparation of the ferrous hydroxide, which conductedthe survey of10and13preservice chemistry teachers teaching ability, throughcomparative analysis the following conclusions:(1) Chemistry students experimental basic literacy level is very high.(2) Basicability of experimental chemistry students on the whole have been developed anddifferent experimental type development level is not same.(3)Different degrees of development of experimental teaching ability in chemistry teachers，teachingappraisal ability and experimental teaching demonstration ability development of thebest, teaching design ability, and teaching organizational capacity needs to beimproved.(4)Experimental innovation ability in chemistry students and researchconsciousness should be improved.Through the analysis and comparison of experimental teaching ability ofdifferent grade chemistry teachers, in term of the shortage of the ability of normalstudents in the development of experimental teaching，Providing reference opinionsand suggestions on the construction and reforming of chemistry course for students innormal colleges and universities.
