There are 75 cows and 34 sheep on a boat. How old is the captain?

This topic examines students' thinking ability. Many students only know how to add and subtract simple numbers when doing the questions, but forget the contents of the questions themselves, which makes it difficult to understand the questions. This problem is to break the conventional thinking and cultivate children's questioning spirit.

It is said that a French educational psychologist once gave a question to children in Shanghai: "There are 75 cows and 34 sheep in a boat, so how old is the captain?" Experts believe that if a student gives an answer, it means that the school has taught the child stupidly. Experts used this joke to test pupils and junior high school students in a city in China, and the result was as high as 90%. Even in the third grade of a key middle school in Shanghai, 10% students still get the answer of 75-34 = 4 1 year. Only 10% students think this question is ridiculous and can't be answered. Of course 10% of the students got it right, because the topic is just a European joke and there is no answer. These students who answered the questions said, "The questions given by the teacher are always right, so it is impossible not to do them." "The teacher usually teaches us that we can get points by doing the questions, and we can't get points without doing the questions." Some students think that if added, it should be 75+34 = 109 years old. You can't be a captain at this age, you can only be 4 1 year old. French experts lamented that students in China listened to their teachers very much, because more than 90% of the students raised objections when doing experiments on the same topic in French primary schools, and even laughed at the teacher as a "stupid egg".

Thinking set, also known as "inertial thinking", is a special mental preparation state or activity tendency caused by previous activities. Under the constant environment, the fixed situation enables people to solve problems quickly by using the methods they have mastered. When the situation changes, it will prevent people from adopting new methods. Negative mentality is a shackle that binds creative thinking.
