Teaching Algorithmic Thinking in the Digital Era:A Backward Design Framework and Action Practices
In the digital era,future digital talents need to possess digital literacy and skills,with computational thinking being a key representative.As a core element of computational thinking,algorithms have become one of the six major logical threads in the newly revised Information Technology curriculum standards.The new curriculum,aimed at cultivating future digital talents,specifical-ly includes a module named"Algorithms Around Us",highlighting the emphasis on developing students'algorithmic thinking.So,how can the cultivation of algorithmic thinking be effectively integrated into classroom teaching?The study adopted a design-based research methodology,grounded in the theory of big ideas teaching,and combined the characteristics of algorithmic thinking with the intrinsic instructional mechanisms of problem-solving.It proposed a backward instructional design framework focusing on fostering al-gorithmic thinking.After three rounds of action-based practices,testing,and iterative revisions,a"three-stage four-loop"design framework was developed.This framework not only provides an operational template for teaching algorithmic thinking in the digital era but also serves as a reference for competency-oriented unit teaching design.
