Now, primary students learn cooking at school. It has been discussed by teachers and parents. Some think that it is a useful skill for students, while others think it’s a waste of time, and some even think it’s just a show. But do they really understand cooking
It’s been said that good cooking is an art form. The truth is that it’s much more than that. When talking about different foods from all around the world, or cultures and histories of dishes, students are connected to the world and learning history and culture in a new field. When learning cooking, students measure (称量) materials from time to time, or find oil and water don’t usually mix. Students are also learning math and science in practice.
The importance of failures in making food is as much as successes. Liu Yu, 11, was crazy about the yummy cakes made by her father and wanted to make one on her own. But when taking her cake out, she was disappointed to find that the cake was hard and black at the bottom. Her father told her that when he was 13, he tried to make cakes, but wasted boxes of eggs. Then, together with her father, Liu Yu found out what had gone wrong and succeeded in making one for the first time. Liu Yu learned from the failure of cooking, and could be braver to face failures.
Apart from the practical skills, cooking builds character. It encourages kids to work with others. It also encourages them to be open to foods they might not have tried. Though being good for our health, carrots were hated by 12-year-old Xiao Kun. But he started to love them after he made a salad with them. By cooking, students put down their phones and work together with family members in the kitchen. By cooking, students form the habit of doing labor work. As a part of labor education, cooking is a way to teach kids necessary skills in the 21st century, such as creativity, teamwork and so on. If these skills aren’t taught to today’s students, they might hardly survive (生存) in the future.
