In another example, second graders made “Place Value Monsters” using blocks that each had a value of 1, 10, 100, or 1000. Each student had to hit at least a three or four-digit number with their animal and then figure out the exact “value” of their creature. “The project reinforced the math content while allowing students to be creative and problem-solve,” says Katie Farrar.
改善: 我能做得更好吗?
虽然用批判的眼光评估他们的工作对幼儿园的孩子来说是一个挑战,但随着时间的推移,构建,测试和重新设计成为一种习惯。
例如,今年秋天,小学生们在读完这本书之后建造了桥梁 第21章大象与静止 贝博体育布鲁克林大桥的建筑。 学生们必须只用冰棒棍和纸杯,搭建一座能容纳21只迷你熊或立方体的桥。 其中一组设计了一座精致的六层桥,而另一组则在设计单层桥时遇到了困难。 为了获得成功,每个小组都必须测试多种解决方案。
Later this term, second graders will be building pinewood derby cars and tweaking their vehicles’ weight, design, and aerodynamic features to decrease the travel time down the ramp.
一年级老师吉尔·吉本斯指出,这些项目帮助学生明白,完美不是目标。 “One student this year said, ‘Practice makes progress!’” says Jill. “I love that because this is completely about the process.”
幼儿园老师Lillian Bogaert对此表示赞同。 “The children definitely get frustrated when it’s not working,” she says. “But that’s good productive struggle. When it does work, it’s so much more exciting because they had to work so hard to get it right.”
