Flowcharts as a representation for planning algorithms¶

Element · All elements
Evidence · no claims cited

Description¶

The deck introduces flowcharts as a planning representation, defining them as "A diagram that shows a process, made up of boxes representing steps, decision, inputs and outputs". It connects flowcharting to algorithm construction, noting that a step-by-step program "will need planning, and to do this we use an algorithm", and points teachers to a YouTube video. This aligns with the Kentucky standard M-AP-04 on creating flowcharts and pseudocode.

Design Implications¶

Context¶

Requirements¶

• Teachers need diagram materials and the referenced YouTube video to implement the flowchart activity

Constraints¶

Target Learners¶

• Students in grades 3-8, with flowcharts and pseudocode named in the middle-grade standard M-AP-04

Target Learning Goals¶

• Representing a process as boxes for steps, decisions, inputs, and outputs before coding
