ists, do you have questions of your own about science?”After a long wait, a boy put up his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?” This began a lot of questions that lasted nearly two hours.Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, many teachers usually wait only one second or less for an answer, no time for a child to think. When teachers increase their “wait time” to three seconds or more, children give better answers.Thirdly, watch your language. When the child is having a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it es to encouraging a child to help others. But in talking about science, these words make a child think that the discussion is over. Instead, keep things going by saying, “That’s interesting” or “I’ve never thought of it that way before”, or ing up with more questions or ideas.Lastly, show。 don’t tell. Let children look at their hands through a microscope(顯微鏡), and they’ll understand why you want them to wash before dinner….81.
