Research On Teaching Design Of Junior Middle School Physics Based On Cultivating Students' Scientific Literacy

Physical concept is an important part of physics teaching in junior high school,and cultivating students' scientific accomplishment is the fundamental goal of physics teaching.In the course of teaching,helping students to establish correct physical concepts is not only an important part of physics teaching,but also a guarantee for improving the quality of physics teaching.Due to the pressure of the exam-oriented education,many a line in the teaching of physics teachers only pay attention to scientific knowledge and skills to teach,often ignore the teaching of the scientific method and scientific attitude,scientific spirit,they are eager to instill in students physical knowledge,and not pay attention to the formation of physical concepts,commonly used repeatedly forced the students to learn physics concepts and learning by rote.In this thesis,based on the modern education psychology theory,uses the method of literature review,summarized method,interview investigation method,case analysis and other research methods,to the junior middle school physics concept teaching design and the cultivation of students' scientific literacy is studied.In the first chapter,we discuss the background of topic selection,research purpose and significance,research ideas and methods,and define relevant concepts.In the second chapter,we summarized the main research achievements of domestic and foreign scholars from three aspects: the teaching of physics concept,teaching design and training of students' scientific literacy.In the third chapter,we summarize the relevant contents of cognitive learning theory,constructivism learning theory,discovery method learning theory,and meaningful learning theory.In the fourth chapter,we discuss the problems related to the cultivation of students' scientific literacy from three aspects: the present situation of science literacy in China,the significance of cultivating scientific literacy and the teaching design of physical concepts.In chapter five,we based on the cultivation of students' scientific literacy,combining with the teaching content of physics concepts in junior high school,and creatively designed three teaching cases of physics concepts.In the "description of sports" teaching cases,we stimulate students' interest in learning by displaying the homemade cheetah pictures and car pictures,and cultivate students' observation ability and thinking ability.Through the design of teaching activities such as carton movement,students can feel the demonstration experiment and demonstration method,better understand the relativity of object motion,and experience the process and method of scientific research.By displaying the self-taught teaching AIDS of the train movement,the students can experience the train movement,train the students' cooperation ability,and train the students' scientific attitude and scientific spirit.Through the design of classroom practice,let the students to remember the concept of reference,to understand the relativity of movement and stillness object,train the students' ability to use knowledge to explain everyday phenomenon,make the students master the corresponding scientific knowledge and skills.In the teaching cases of "quality",we can cultivate students' observation ability and thinking ability by making students observe and experience iron nails and hammer,and feel the quality of different objects.By showing cream leather shape change and the change of the position,let the student feel in the exchange experience the invariance of masses,cultivate the students' scientific thinking ability,communication skills,and cultivate the students' scientific attitude and scientific spirit;Through the design of classroom exercises,students can further master the concept,unit and conversion formula of quality,thus teaching students the knowledge and skills of science;We also construct a series of interesting activities,let the students in the process of learning the use of the counter balance,hands-on experience fun,cultivate the students' observing ability,operation ability,cooperation ability,cultivate respect facts and the law of scientific attitude and scientific spirit.In the case of "density" teaching,students' observation ability and thinking ability are cultivated by allowing students to observe and experience bubbles and soap boxes,water and alcohol.Design experiments to explore activities,and guide students to explore the relationship between the mass and volume and density of the object,let students experience and learn ratio method,the scientific research method by asking questions,caused the students guess and divergent thinking and cultivate the students' questions about quality and creative ability,as well as the unity and cooperation,realistic scientific attitude and scientific spirit;By teaching historical stories and measuring the density of objects in life,students are encouraged to learn more about the science of density.The above three teaching design case,we educationed in the yueyang No.10 middle school,and make the education research in the form of interviews,found that the teaching design is helpful to cultivate the students' scientific literacy.
