High School Students Using Language Barriers And Transformation Of Chemical

In practical teaching,the author found that high school students have serious problems in chemical language learning and use,directly restricts students to follow the learning of chemistry knowledge,the high school students more and more to fear generated by chemical,slowly on chemical lost interest,and even disgust escape chemistry.By reviewing the literature,defines the core concept of chemistry language,it is considered that the chemical language is produced in the chemistry discipline,the formation and development process,people in order to be more accurate,more convenient,more easy to describe,record,a specification for inheritance of chemical knowledge and chemical method to do the language(including chemical element symbols,chemical formula,chemical formula,ion chemical symbols,graphics,structure etc.)and chemical terms(specific name and special language expression)two categories.Then,the chemical language of Dangchang County Rural High School and high school in August 2016 new enrollment of 261 students were surveyed using the situation,found that high school students in the chemistry language use there are serious obstacles,and the rural high school is more outstanding.By interviewing some teachers and a new high,identify and analysis in chemistry in senior high school language causes disorder;for these reasons,put forward five transformation strategy,and the conversion strategies used in the classroom teaching,research into practice:Sha Wan Dangchang County high school 86 freshmen,formulated by the author with transformation strategies The teaching design,classroom teaching;middle school and Dangchang County hada Dangchang county first middle school 175 students without any treatment,the original teachers continue to teach,as the control group.Regular on 261 high school students using the language of chemical measurements,which results in the control group after the test,found a large discrete degree,two stage differentiation phenomenon is serious,and the results of discrete degree is low,performance is relatively concentrated,namely experimental group and control group after the test results there is significant difference.The three schools will be measured after the longitudinal comparison of measured data and data before high school students in rural areas,the average scores were increased,and the experimental group,the maximum growth rate;range(R)of experimental group was significantly decreased,the control group increased significantly;the standard deviation(s)of experimental group decreased slightly,the control group increased significantly;the control group the distribution of data compared with the normal distribution,which showed a negative bias.The effective implementation of the use of language barriers chemical transformation strategy,to a certain extent,improve the experimental group students school chemistry language disorder,the Bay high school students chemistry language level has improved significantly.
