"The Design Of Glass Bead Collision" Inquiry Activity

In the traditional education of science classroom, teachers blindly pursue short-term results and effect. Thereby, the "spoon feeding" and "teach" teaching method, ignore the students hands-on ability and good scientific literacy training, these problems has been the subject of widespread concern in the education sector. And the Ministry of education to develop science curriculum standard proposed:science curriculum to improve each student’s scientific literacy as the goal, through the course of learning to enable students to experience the process of scientific inquiry, enhance understanding of scientific inquiry, the cultivation of students’scientific inquiry and hands-on design ability, initially formed the habit of scientific inquiry. Therefore, scientific inquiry is one of the main directions of the reform of science education curriculum.The case of teaching and learning activities mainly focus on this theme of "bead collision" research and design, the main contents as is collision and oblique collision and application migration. Through the layers of the collision and oblique collision related issues and phenomena introduced, then let students scientific inquiry activity, let the students master the knowledge of collision:the mechanical energy conservation knowledge and momentum conservation knowledge; at the same time, students to carry on the scientific inquiry activity.The first class is mainly focus on such a question:"when you play bead?" To stimulate students’ curiosity and knowledge motivation. Section 2 is mainly through the observation of the glass bead collision sport, allowing students to find out the question, also let the students initial contact with the hit it. The third section is mainly about the phenomenon of the last class, and let the students grasp the concept and construct a positive physical model and theoretical deduction.. The fourth class, exploring pendulum collisions in the main ball dropping height and the height of the relationship between the ball. The five classes of simple pendulum impact of a theoretical derivation and analysis of the main touch touch the glass bead dropping height and a touch bead touch after the rise of the relationship between the height of. The sixth section of the lesson, for example, is a life transfer application of knowledge. Lesson 7 is mainly glass bead oblique collision experiment to explore the impact of scattering angle and theoretical deduction. Lesson 8 describes the application of oblique collision of life:Billiard collision. The ninth section is the summary of the course, the generality and the difference between the positive and the oblique touch..The inquiry activity teaching and traditional physics teaching design:(1) on the learning methods and to group inquiry learning and collective discussion in the form of a combination of, the advantages of both complement each other, in the cooperation study; (2) in the teaching mode, students explore and teachers guide supplement, let the classroom truly become a student of master; (3) in the material aspects, close to the life makes it easier for students to understand.
