A Research On Large Unit Design Oriented To Scientific Thinking In High School Physics

Since the 21 st century,the international curriculum reform with the goal of developing the core literacy of teenagers is in full swing.In 2014,a new round of curriculum reform guided by core literacy has been launched in China,and large unit design is an important way to realize the implementation of core literacy.Therefore,teaching design based on large unit has become an important research topic.In this study,the author chose scientific thinking,a key dimension of the core literacy of nuclear physics,as the training goal to carry out the research on unit teaching design.First of all,the author analyzed and summarized the research status of "physics core literacy","scientific thinking"," unit teaching design ","physics unit teaching design" and other related contents,defined these related concepts,and a discussed the necessity and significance of carrying out the research of unit teaching design oriented to scientific thinking.Secondly,the author analyzed the theoretical basis of this study,and defined the constructivist learning theory and humanistic learning theory as the guiding ideology of this study.Then,the first mock exam of Understanding by Design was chose as the design of the large unit in this paper,and the detailed analysis of how the unit teaching design is carried out under this mode was presented in this paper.Based on the "Three-stage" theory,the process of unit teaching design was divided into three stages and eight steps: 1,Find out the big concepts and core tasks;2,Determine the unit teaching objectives;3,Put forward the basic problems of the unit;4,Clarify the expected learning results;5,Find the evidence of unit evaluation;6,Design the unit evaluation criteria;7,Analyze the basic situation of students;8,Design the unit teaching activities.Finally,the author chose to reconstruct a topic unit by using the knowledge of Newton's second law,acceleration,free falling motion,inertia,overweight and weightlessness in high school physics.The core content of the unit is Newton's second law.In the fourth chapter of this study,the unit was designed.In the process of design,the author fool that there are at least four advantages in the teaching design by using the mode of Ub D.First,the teaching design guided by the mode of Ub D truly embodies the teaching principle of students as the main body,and its design is always around the students.The design teachers at each stage need to consider "students can..." and "students will...".Secondly,the model simplifies the teaching design procedure,which integrates the design of the goal,the design of the key and difficult points,the analysis of the teaching content,the design of the teaching method,etc.into the stage 1 to determine the expected goal,and makes the original complicated teaching design program simple and concise;thirdly,the teaching design of the Ub D mode has strong logic and systematicness.The design of the three stages is the ring the teaching design of Ub D mode is to determine the unit learning goal,point out the end point of students' learning,and plan the design route.Teachers can directly root in the design process when they start the design According to each link of route design,it not only avoids the deviation between teaching design and teaching theme,but also saves the time for teachers to write teaching design.Through the research of the first mock exam,the author hopes to provide some references for the teaching design of the teachers.
