| Physics is a subject based on experiments.Experiment teaching plays an important role in Physics Teaching in the senior high school.Physics experiment with the characteristics of directness, practice, creation, is an important means to help students master the scientific research method, construction of physical knowledge and improve the hands-on ability. The use of multimedia technology in physics experiment teaching in the senior high school is helpful to overcome the disadvantages of traditional experiment teaching and improve the experimental teaching conditions and the teaching method of the experiment. Researches on theory and practice of computer technology into the real classroom of experiment of physics are the necessary stage for physics teaching information.The Geometer’s Sketchpad is an excellent teaching software platform, which has been widely used in mathematics, physics and other disciplines. It is economical,practical and easy to learn; Not programming can realize the dynamic graphics, a variety of functions such as data processing; Geometric Sketchpad can create a dynamic graphics "experimental" environment, which help the teachers’ leading role and students’ main body the play.Based on interviews with teachers, the paper explores the present situation of the application of multimedia technology in physics experiment teaching in the senior high school, and analyzes the difficulties of computer technology and the integration of physics experiment teaching. Based on constructivism and the theory of cognitive development as the instruction,it adopts the methods of literature, interviews, and summarizes the current textbooks of senior high school physics experiment, construction of the Geometer’s Sketchpad in different types of experimental teaching mode; Finally,the case analysis and experimental study of contrast, help to demonstrate the effectiveness of The Geometer’s Sketchpad assist high school physics experiment teaching. |
