An Experimental Study On Improving The Development Of Students' Cognition In Junior High School Chemistry Experiment

It is commonly considered that chemical experiments play an irreplaceable role in the chemistry teaching.In order to enhance the significance of chemical experiments in teaching,and excavate the potential opportunities in real practice and modified experimental methods,on the purpose of promoting the students' cognition to discuss the importance of modified chemistry experiments teaching and management strategy which are based on the school-based curriculum.This work involves multiple investigation methods including document investigation,action research,comparative study,statistical analysis,and experience summarization,et al.We rely on the platform of "The Second Batch of Junior Middle School Chemistry Teaching and Research Base in Fujian Province "---Fuzhou NO.32 Middle School and Fuzhou Zexu Middle School as the objects of study to perform relative action researches,taking the demonstrating experiment teaching and students' grouping experiment as examples shown in the current junior chemistry textbook(science edition)in Fuzhou,also combined with case analysis,and based on the students cognitive development we make the teaching designs and assessment strategies,including the teaching procedure,continuous problem chain design,contrast experiment design and improvement of teaching evaluation.Meanwhile,combined with practical research,clear the principal's leadership responsibilities in curriculum development of Chemical modified experiment,and present curriculum leadership strategy which focus on the curriculum management.
