Practical Research On Cultivating High School Students' Chemistry Experiment Literacy Based On Project-based Learning

In the"General High School Chemistry Curriculum Standards"newly issued by the Ministry of Education in 2017,it is clearly stated that education should attach importance to"quality-oriented"teaching,advocates teachers to open questions derived from real situations,and carry out exploratory activities based on experiments.,It helps middle school students to deeply understand the importance of experiment to chemistry learning^[1].The thesis introduces project-based learning into the high school chemistry experiment"laboratory preparation of ammonia"class,clarifies the content of learning,applies the teaching concepts and ideas of project-based learning to construct experimental teaching programs suitable for high school students,and implements teaching.It takes one week to carry out project-based learning experiment courses,and through a series of evaluations of the experimental courses,conclusions are drawn,which provide some useful references for the majority of educators,and at the same time provide some reform directions for the teaching methods of middle school chemistry experiment courses.Combining literature research and practical research,this research is divided into five chapters:The first chapter mainly introduces the source of the topic and the research background,from two perspectives-the requirements of the new curriculum standard for experimental teaching and the existing problems of the existing teaching model to illustrate the feasibility of this research.Through the literature,I learned about the current research status of project-based learning and the current teaching status of chemical experiments,which laid a theoretical foundation for the article.The overall thinking design of this research is discussed,the research objectives and research content of this article are clarified,and the research significance is explained from theory and practice.The second chapter discusses the core concepts of project-based learning,chemistry experiments,and chemistry experiment literacy,and reviews its theoretical basis.Chapter 3 summarizes the research on the textbook experiment and its classification,expounds the choice of the experiment,then uses the project-based learning theory,combined with the real teaching in the classroom,and designs the project-based learning teaching design of"Laboratory Preparation of Ammonia".The fourth chapter is the practical research of project-based learning of"Laboratory Preparation of Ammonia".Before the start of the experimental teaching,three tasks were assigned to the experimental subjects to collect the completed data;at the same time,the"project-based learning questionnaire"and"the"Ammonia Laboratory"experimental operation scale"were used as evaluation methods,and the experimental class began The pre-test was conducted before the teaching,the post-test was conducted after the teaching,and the classroom process evaluation was conducted in conjunction with teacher evaluation.After sorting and analyzing the collected data,the following conclusions are drawn:(1)Project-based learning can promote the change of students'active learning and learning attitude,and stimulate students'interest in learning;(2)Cultivate core literacy of subjects and enhance students'comprehensive ability.(3)Cultivate students'experimental operation ability,promote the transformation of students'experimental attitude,improve experimental cognition,and enhance experimental thinking.The fifth chapter draws conclusions from the conclusion of this research,and reflects and prospects:carrying out practical teaching with project-based learning teaching mode can increase students'interest in learning,promote students'active learning,and cultivate core literacy and experimental thinking of students,Improve students'comprehensive ability and experimental cognitive ability,recognize the important position of experiment in chemistry teaching,understand the importance of chemical experiment;at the same time,it also summarizes the shortcomings of this research.
