The Exploration Of The Design And Application Of Chemistry Learning Case In Junior Middle School

In recent years,the pace of basic education reform has been continuously promoted.The wave of new curriculum standards has also impacted the traditional teaching methods.New teaching program requires that students should become the main body of the class.Instead of blindly accepting knowledge,students should actively explore knowledge under the guidance of teachers.They need to have the ability to collect and process information,analyze and solve problems,as well as communicating and cooperating.This puts forward higher request to the teacher's teaching mode and the student's learning method.In order to cultivate students' scientific literacy and improve their comprehensive ability,the learning mode of independent inquiry has become the most popular teaching mode by the public.The teaching mode of guided learning case is one of the widely used modes of independent inquiry.After analyzing the current educational background and combining with the research status at home and abroad,this paper finds that the teaching mode of guided learning plan has been widely used and the research on guided learning plan is also rich.However,there are relatively few researches about the design of guided learning plan and the analysis of classroom practice.This study is divided into four parts.The first part focuses on the background of the topic.It shows the status quo of the teaching and research of guided learning program,and summarizes the relevant theories at home and abroad.The second part focuses on the design of the learning cases.In the research process,I visited a numberof local schools to investigate how they use the learning cases.According to the needs of junior high school chemistry classes,I designed and applied guided learning plans for teaching practice with the help of teachers with rich teaching experience.In junior high school,chemistry class is divided into three categories: concept and principle class,element and compound class and chemical experiment class.The concept and principle can be subdivided into macro concept and micro concept.The element compound can be subdivided into the symbol representation of element and the property of substance.The chemistry experiment class can be divided into basic experimental operation and experimental exploration.This article shows the five different class type of learning cases and teaching cases,inclouding chemical element and symbol of learning case,chemical experiment learning case,chemical concepts learning case,microscopic concept learning case,and chemical comprehensive application subject class tutorship case.In the third part,after the teaching practice,a questionnaire survey was conducted on the application practice of the learning case.The students and teachers who use these learning case are selected to conduct the questionnaire survey.The information feedback has been collected,and the data is analyzed to find out the influence of the guided learning case on the students' learning and teachers' teaching.In the last part,the research results are summarized,and the problems that need to be paid attention to in the design and application of the guide plan are put forward to complete the research.The results of scientific research and investigation data analysis show that the design of the instructional plan in this study is reasonable and the expected effect of instructional plan is achieved.In the application process of guided learning plan,90%of the students prefer the teaching method of guided learning plan,and 79.2% of the students think that guided learning plan plays an important role in improving the learning efficiency and consolidating the learned knowledge.In class,60% of teachers often use the guided learning plan,and 56.2% of teachers believe that the guided learning plan plays a role in improving classroom efficiency and cultivating students' independent learning ability.Through the guided learning program teaching,teachers have formed a student-oriented teaching model,which is also helpful to theimprovement of teachers' personal qualities.In order to provide theoretical and practical guidance for the design of guided learning plans,the common problems in the design and application of guided learning plans were put forward.
