As socialism with Chinese characteristics has entered a new era,China is accelerating its march toward an innovative country.In order to implement the fundamental task of "cultivating morality and cultivating people",the "General High School Curriculum Plan(2017 Edition)" was published,making the development of students’ core literacy the general goal of basic education.Therefore,it is urgent for educators to explore and implement new teaching theories and practices of core literacy.Deep learning emphasizes memory based on understanding,deepens the original knowledge system,gradually deepens understanding,develops the ability of higher-order thinking and critical thinking,and transfers knowledge and ability to practice.Deep learning is an inevitable trend in the development of international education and a favorable means to realize the core literacy of chemistry.The "deepness" of deep understanding,information association,higher-order thinking,and transfer application of deep learning needs to be realized through the "big" of content integration,step-by-step advancement,task-driven,and situational transfer of large-unit teaching.Therefore,the teaching practice of high school chemistry unit based on deep learning is effective for developing students’ core literacy of chemistry.This paper mainly studies from the following five aspects:The first part is the introduction,expounding the significance of this research topic.Through literature research,we can understand the relevant theories of deep learning and largeunit teaching at home and abroad,and sort out their development stages.Based on the existing research results,understand the deficiencies of the existing research and put forward research questions,and formulate a research plan.The second part is the theoretical basis and concept definition.Understand and analyze the connotation,characteristics,occurrence mechanism and evaluation of deep learning theory.Summarize the connotation,characteristics and existing practical achievements of large unit teaching.So as to determine the concept and framework of this research.The third part is an analysis of the current situation of high school chemistry unit teaching based on deep learning.Through the questionnaire survey and teacher interviews,the students’ in-depth learning level and the application and practice of teachers’ large unit teaching in high school chemistry were understood,and the main problems in chemistry teaching were summarized and the reasons were analyzed.The fourth part is the construction of a large unit teaching model of high school chemistry based on deep learning.By analyzing the research status and practical pain points,based on the deep learning DELC route,large unit instructional design process,Gestalt psychology theory,distributed cognition theory,metacognition theory,and core literacy of chemistry,a deep learning-based high school chemistry university is proposed.Unit teaching practice model to promote the development of students’ deep learning ability.The fifth part is the teaching practice of high school chemistry unit based on deep learning.According to the teaching practice model of high school chemistry based on deep learning,taking "iron and its compounds" as an example,the Case Study method is used for teaching design and practice,and the teaching effect is qualitatively and quantitatively analyzed.The SPSSPRO platform is used to analyze the students’ learning effect,and then draw the research conclusion.Deep learning is of great significance to cultivating new talents in the new era,and largeunit teaching is an effective way to promote students’ deep learning.This research hopes to provide specific teaching ideas and plans for Chemistry teachers to carry out large-unit teaching design and practice,so as to promote the optimization of education and teaching,improve students’ in-depth learning level and ability,and make them adapt to future social development,and explore more ways of new curriculum reform. |
