Design And Practice Of Deep Learning-based Review Of Chemistry Micro-project Units In Junior High School

Under the background of "double reduction" policy,it is a challenge and an opportunity for contemporary education to realize the improvement of teaching quality.It puts pressure on educators and injects impetus into education reform.Deep learning starts from the revelation of problems.Students start thinking around problems,take knowledge as a tool to solve problems,and carry out a series of inquiry activities to cultivate the ability and quality of solving problems,so as to implement the task of building virtue and cultivating people,deepen the reform of compulsory education stage,and cultivate the core quality of disciplines.Project-based learning,on the other hand,provides a set of operational steps from the beginning of problems to the formation of results by solving problems,so that the concept of deep learning can be put into practice in classroom teaching.The teaching content of junior high school chemistry review course is fragmentary,and the teaching method is monotonous and boring,which leads to the low enthusiasm of students in learning,and then affects the review effect.Through research,micro-project learning based on deep learning background provides a new idea and way for junior high school chemistry unit review.This paper mainly studies the following contents:The first part describes the background of the study,the overall design of the study and the domestic and foreign research review.Through literature review,it is found that the current research on chemistry teaching design in junior high school mainly includes the following keywords: core literacy,deep learning,integrated unit teaching,and project-based learning.The course type of the research is mainly new teaching,and there is a lack of thinking on the teaching design of review course,and fewer studies combine review course with theory.Based on this,the research idea is preliminarily determined and the title of this research is finalized.The second part is the definition and theoretical basis of the core concept.The core concepts such as deep learning,project-based learning,micro-project learning and unit teaching are defined,and the theoretical basis of instructional design in the context of deep learning and project-based learning is briefly described.The third part is about the investigation of "deep learning" and "review course".A survey was conducted on the current situation of deep learning and chemistry review class among junior middle school students in a middle school.It was found that junior middle school students were still in the surface learning stage in chemistry review class,but their motivation and attitude towards chemistry learning were relatively positive,and there were conditions for the development of deep learning.The status quo of chemistry review class was investigated by randomly selected chemistry teachers of junior middle schools in Tongliang District,and the deep learning was interviewed by junior middle school teachers of a middle school.It was found that the teaching methods of chemistry review class were also very different,and the understanding level of junior middle school chemistry teacher groups on deep learning was uneven.The fourth part is the teaching design research of junior high school chemistry micro-project unit review based on deep learning.The basic links of deep learning and project-based learning are organically integrated to form a deep learning-based teaching design framework for micro-project unit review,including: Reconstructing the teaching unit,establishing the target theme,sorting out the unit objectives,forming the problem chain,combining with the real situation,setting the activity task,promoting the development of the project,conducting activity exploration,forming the project results,scientific evaluation and reflection of the five links,and each link is elaborated and explained in detail.The fifth part is the teaching design practice of junior high school chemistry micro-project unit review based on deep learning.In part ii unit 9 o ’clock nine grade "solution" as an example,the reconstruction unit teaching content,establishing "make a weather bottle" micro subjects,divided into three components "know the weather bottle",the principle of "weather","make a bottle" weather,layers of progressive,in driving problems and project activities,To complete the review and consolidation of knowledge content,the improvement of ability,and the formation of thinking.The whole teaching case makes a detailed description from the aspects of selecting project theme,setting project activities,implementation of project activities,evaluation of project activities and so on,which can be used as a reference for front-line teachers.The sixth part is the research conclusion and prospect.On the basis of domestic scholars’ research on deep learning and project-based learning,the author analyzed the role of deep learning in improving the efficiency of review classes by combining the current situation of deep learning and review classes for Grade 3 students and teachers in my school,as well as the current situation of review classes for teachers in my district and county,and proposed a teaching design framework for micro-project unit review based on deep learning.And design examples for teaching practice.In practice,this paper summarizes the innovation and shortcomings of this research,and points out the research direction and teaching expectation.
