Research And Design Of The Project-based On "Chemical Balance"

Chemical balance is one of the core concepts of the high school chemical reaction principle module.It has important guiding significance for learning other balance systems,and it is also a knowledge carrier of literacy "changing concept and balancing thoughts".The new curriculum standard has weakened the depth of the course of chemistry balance and paid more attention to the development of core literacy.The abstract property of chemical balance knowledge is a huge challenge both for teachers and students.How to grip students' attention on stale knowledge in a time-critical and fast-paced review situation,and how to develop students' core academic literacy are common problems faced by front-line teaching at present stage.Based on these two points,this paper carries out teaching research in order to improve the current situation of traditional teaching methods and provide reference for further chemistry review needed.This research adopts the methods of literature research,questionnaire survey,classroom observation and paper-and-pencil test.The advanced research content is divided into five chapters:1.The first chapter introduces the research background and the source of the topic,which expounds the feasibility and necessity of this research from the two aspects of the content characteristics of chemical balance and the basic requirements of the education of chemistry subject under the socialist core values.Through the literature to understand the current chemical balance and the review of the third year of teaching status,the analysis of the project learning theory and its integration with the subject research status,for this paper to lay a theoretical foundation for the further research.2.This part discusses the overall design of this research,clarifies the research objectives and contents of this paper,which has described the significance of work both from theoretical and practical aspects,and introduces the research strategy of this paper.3.At this part,the contents of the knowledge are firstly analyzed related to chemical equilibrium from the aspects of curriculum standards and textbook contents.Then,the accomplishment of "changing concept and balancing thoughts" in chemical equilibrium is deeply interpreted based on the key competence of the discipline's core accomplishment.Combined with previous college entrance examination chemistry test,the contents of the chemical balance examination and the level of competence are further assessed.Moreover,based on the theory of project learning and real situation in teaching process,the teaching design of chemical equilibrium is greatly improved.4.Based on the research of the teaching design of project-based learning,this part introduces the objectives and process of the practical work,and the results of the improved experimental strategy are mainly estimated from the two aspects of classroom observation and test results,and the reason of results are also analyzed at the same time.5.this part of work reflects and anticipates the research,and summarizes the shortcomings in the research process.In summary,it can be found that project-based leaning based on real situations can greatly attract the interest of students.And it also contributes to the cultivation of students' core quality of the subject,which means truly achievement from "knowledge-oriented" to " literacy-oriented" teaching concept.
