Research On Quantitative Experiment Teaching Of High School Chemistry Based On Chemistry Core Competence

Nowadays,with the rapid development of big data and science and technology,those who don't study will fall behind and will be eliminated by this era.Under the circumstances,the theory of core competences of lifelong development after separation from books has been gradually recognized and paid more and more attention by educators.For chemistry teaching,chemistry core competences has become the primary goal of chemistry teaching.Although a large number of studies on it have appeared in recent years,most of them are not in-depth or detailed enough to provide operational suggestions and strategies according to different branches in the field of chemistry.Aimed to cultivate chemistry core competences,this essay analyzes how to put it into the practice of chemistry teaching about quantitative experiment in senior high school.What's more,the conclusions are drawn and the strategies are put forward through the test and survey of senior three students,as well as the survey and interview of teachers.Based on reviewing and organizing literature on this topic and interpretation of the new curriculum standard,this essay defined the concepts of chemistry core competences and briefly introduced the theory of cultivating chemistry core competences.Furthermore,the ability level of quantitative chemistry experiment of senior three students was measured,the development of chemistry core competences were analyzed,and the learning status of students was also investigated through tests and questionnaire,combined with the actual situation.It is found that the ability of quantitative chemistry experiment of senior three students is relatively low,their chemistry core competences need to be further improved,and their interest in studying needs to be further stimulated.The good news is that students are not only willing to explore,but also willing to be engaged in social practice.The essay reveals the current teaching situation through the investigation and interview of students and teachers,that the current school experiment equipment is basically complete,and that students are still lack of experiments,which all prove the feasibility of cultivating students' chemical core competences in experiments.In order to solve the problems appearing in the current investigation,this essay,with the combination of relevant theories,formulated the teaching design and activities of acid-base neutralization titration to discuss how to cultivate students' chemistry core competences in specific classes according to teaching strategies.Focusing on the principle of“less telling and more exploration”,the design is organized to help students solve the problems step by step and level by level in the form of tasks,and to help them to put what they learned into practice.Finally,the essay ends with a summary and prospect of the future of relevant strategies.
