"Jujube Tree and Watermelon" is the second short article in "Little Carp Jump Dragon Gate". Jujube trees and watermelons are different and have their own advantages, just like the students in the class. Second graders have no trouble reading this fairy tale, but it is difficult to understand the deeper meaning. What is the deeper meaning? Each has their own strengths and respect for each other. The students can not understand directly, need a "teaching scaffolding" to help.

?

First of all, I read the three conversations initiated by the date tree, and concluded that the date tree is rude and the watermelon seedling is cute. The students read the conversations initiated by the watermelon later, and read the watermelon's doubts.

In order to let students better understand the main idea, I used a double bubble chart to find the **** similarities and differences between the two.

The students copied the drawing of the double bubble chart in class, found sentences from the text, summarized the similarities and differences between the two, and justified the basis of mutual respect, and this pedagogical scaffolding served the desired purpose: summarizing the text, organizing the ideas, and helping to speak.

In order to consolidate the effect and achieve the effect of developing students' thinking and language, I set up a post-course homework: a double bubble chart comparing the same and different between the frog and the goldfish, and orally create a story. The purpose of this design is - and the class studied the "tadpoles looking for moms" and the first unit of oral communication "cute animals" to produce knowledge cascade, knowledge construction and innovation.
