Although light and shadow cannot be touched or touched, they can affect people's perceptual experience and feelings; light and shadow are divergent, can extend infinitely, become larger or smaller, and can also present different effects at the projection distance from objects. This theme teaching is based on light and shadow. It originated from the hot summer. I watched the children move from the West Building classroom across the playground to the East Building classroom for class. As soon as they entered the classroom, they shouted "It's so hot! It's so hot." Therefore, the course started with students looking for campus. I started to think about the "shade route" to solve the problem of "being very hot in the sun", and explored the reasons why the "shade route" is not hot, and derived the task of exploring light and shadow on campus.
Thematic teaching starts from problem awareness, observes the changes in light and shadow on campus, and collects children's general discoveries about light and shadow. Then, based on these discoveries or questions raised, a preliminary curriculum structure is planned through curriculum preparation, and the problems discovered by students are discussed. Designed as key questions, and then transformed into group learning tasks through key questions, using key questions to set up a scaffolding for learning, and using multiple teaching strategies such as key questions, problem solving, task orientation, cooperative learning, and publishing and sharing to assist students in learning , it is expected that students can repeatedly practice "thinking about problems g operations g correction g recording g summarizing and integrating knowledge g publishing" through strategies such as observation and recording, cooperative learning, and specific operations, so that doubts can be verified one by one, and finally they can be gained from learning Develop the qualities of "exploring things", "willingness to learn", "expressing ideas and innovative practices", "perceiving and appreciating beauty" and "cooperating with others".
