Research and Practice of Engineering Design Based STEM Teaching Approach on Students'Computational Thinking
STEM curriculum is an important carrier to cultivate students'computational thinking,which in turn can facilitate the development of students'multiple abilities in real-life situations.In the context of new engineering education,this study proposes to organize the teaching process with the engineering design cycle and create a framework for designing STEM teaching activities to support students'computational thinking with the five elements of Smith's framework.The design and implementation of the activity is based on the example of the elementary school"Ship Model"course.A pre-text and post-test experiment with a nine-week follow-up is utilized,supplemented by a task list,to explore the impact of curriculum implementation on elementary students'computational thinking skills and practices.The results of the data show that the curriculum stimulates students'computational thinking ability;the results of the cognitive network analysis show that the implementation of the curriculum promotes students'computational thinking practice,and that students'algorithmic thinking develops significantly and the connection of elements is stronger after the completion of the ship modeling.
