Research And Design Of High School Chemistry Experiment Teaching Based On Micro-project Learning

The rapid development of the information age has put forward higher requirements for ta lent training.In the 21 st century,social and work responsibility,professional ethics,independ ent innovation awareness,ability to work with others,knowledge and culture,and practical sk ills have become essential skills for talent.It can be seen that only passively receiving knowle dge can no longer meet the requirements and development of the current era.It is necessary to take the initiative to apply the learned knowledge to the actual situation,internalize the learne d knowledge into the brain,and learn how to apply it.The chemistry discipline characterized by experiments is one of the main subjects of high school students' learning.Under the new curriculum reform philosophy,the high school chemistry curriculum emphasizes the subjective position of the experiment.However,experimental teaching has been neglected in traditional chemistry education: the teacher's demonstration experiment replaces the student experiment,the student can not experience the design experiment process,the hands-on operation experiment,and neglect the student's subjectivity.In the high school chemistry experiment teaching,the micro-project learning mode is adopted to help the students' subjectivity.This paper reviews the research status of experimental teaching and micro-project learning,analyzes the concepts and characteristics of micro-project learning,summarizes the steps and strategies of implementing micro-project learning in experimental teaching,and discusses the application of micro-project learning to high school chemistry experiments.According to the scores of the senior high school entrance examination,two classes with no obvious differences are selected from the first grade to conduct comparative experiments.The experimental class adopts the teaching method of micro-project learning,and the control class adopts the traditional teaching method and sets various examination methods.By comparison,the results of the demonstration show that the results of the experimental class are significantly better than the control class,indicating that it is feasible to adopt the micro-project learning mode in the teaching of chemical experiments.Therefore,applying micro-project learning to high school chemistry experiment teaching can cultivate students' ability of collaboration and self-learning ability,and at the same time,can cultivate students' interest in chemistry courses,so that students' academic performance and learning attitude can be improved..
