1. Requirements:
1. Scoring criteria: 100-point system, with content accounting for 40 points, effect accounting for 40 points, and appearance accounting for 20 points.
2. The time will not exceed 12 minutes, with 3 minutes for students to ask questions and the speaker to answer.
2. Steps:
1. Arrange 7 people to give speeches every day, and students will be graded on a hundred-point scale. Then each student will rank the 7 people on that day. The first place will get 7 points, the second place will get 6 points, and the 7th place will get 1 point. For example, student No. 3 received 13 votes for 1st place, 4 votes for 2nd place, 3 votes for 3rd place, and 1 vote for 4th place. The total score is: 91+24+15+4=134 points, the number of voters is 21 (21 votes), 134÷21=6.4, because there are 7 people participating, the average score per person is 6.4÷7=0.914 points.
2. On the second day, 7 people gave speeches and 22 people participated in voting. After calculating the total score, divide it by 22 and then divide it by 7 to get the average score per person.
3. And so on the third day.
4． On the fourth day, 4 people gave speeches and 21 people participated in the voting. There was a slight difference: the first place got 4 points, the second place got 3 points...and the 4th place got 1 point. For example, for student No. 2 today, there are 7 votes for the first place, 6 votes for the second place, 6 votes for the third place, and 2 votes for the fourth place. The total number of votes is calculated. It is divided into 28+18+12+2=60 points, the number of voters is 21 people (21 votes), 60÷21=2.9, because there are 4 people participating, the average score per person is 2.9÷4=0.725 points.
5. According to the average score per person, the ranking of the contestants can be listed. For example: the above 0.914 is divided into first place, and 0.725 is divided into seventh place.
