| Abstract: | Randomness in life exists everywhere and so does probability.In the chapter of "Random Events and Probability",the teaching difficult point lies in the relationship between frequency and probability.In order to help students make a successful breakthrough,I design several in-class experiments,including flipping coins,analyzing historical data of flipping coins and simulating the flip on computer.With the help of the geometric sketch cartoon demonstration,students thoroughly understand the theory of probability and the variability of frequency.To sum up,my teaching practice succeeds in correcting students’ former misunderstanding,inspiring them to connect study with life,learning interesting and useful mathematics and cultivating students’ ability to research into mathematics by means of enquiry and experiment. |
