随着计算技能成为21世纪学生的必需品,必须为核心课程创建注入计算思维(CT)课程,以真正为所有人提供计算教育。这将带来挑战,因为学生将有广泛的经验和编程能力。此外,STEM教师可能没有教授CT的经验,使用不熟悉的技术进行教学可能会造成不适。我们提出了一个设计模式注入CT的任务,脚手架的学生和教师到基于块的编程环境。从现有的代码开始,学生和教师一起工作“使用”和理解代码,然后一起“修改”它来修复他们的程序。活动结束时,学生从预设列表中“选择”自己的扩展。我们提出了一个模拟活动的两个实现的比较,一个结束与学生选择如何扩展他们的模型,一个所有的学生创建相同的选项。通过对课堂观察、学生反馈、教师访谈和编程交互日志的三角数据进行分析,我们提出了对学生和教师偏好的“学生选择”模型的支持。最后,我们建议的策略,按照我们的设计模型开发课程。
As computing skills become necessary for 21st-century students, infused computational thinking (CT) lessons must be created for core courses to truly provide computing education for all. This will bring challenges as students will have widely varying experience and programming ability. Additionally, STEM teachers might have little experience teaching CT and instructing using unfamiliar technology might create discomfort. We present a design pattern for infused CT assignments that scaffold students and teachers into block-based programming environments. Beginning with existing code, students and teachers work together 'Using' and comprehending code before 'Modifying' it together to fix their programs. The activity ends with students 'Choosing' their own extensions from a pre-set list. We present a comparison of two implementations of a simulation activity, one ending with student choosing how to extend their models and one having all students create the same option. Through triangulating data from classroom observations, student feedback, teacher interviews, and programming interaction logs, we present support for student and teacher preference of the 'Student-Choice' model. We end with recommended strategies for developing curricula that follow our design model.
