Case 01 — Logo Programming and Mathematical/Written Literacy
Overview
| Item | Content |
|---|---|
| Period | Emerged 1967, spread to schools in the 1980s |
| Technology | Logo (educational language based on shape commands, turtle graphics) |
| Audience | Elementary and middle school learners |
| Literacy | Mathematical, logical, and descriptive expression (an early form of computational thinking) |
Technology Summary
Developed by Seymour Papert’s team at the MIT Media Lab, Logo moves a “turtle” on screen with commands like
FORWARD 100 and RIGHT 90.
With no complex syntax, learners immediately experience the command → result → revise loop.
Literacy Improvement Mechanisms
- Procedural description: Expressing “what to do in what order” as a sequence of commands, just like writing it out
- Using errors as data: A scientific reading/writing habit of revising hypotheses when you see the deviation
- Connecting shapes and language: Operating geometric intuition and symbols (numbers, notation) at the same time
- Making ideas visible: The cycle of mental design → on-screen result → explaining it again
Field Operation Tips (for hands-on programs)
- Have learners first write the “turtle path” as sentences on paper, then verify it on the computer
- Submit the finished shape together with a short piece of writing (why this path was chosen)
- Difficulty sequence:
forward & turn→repeat (REPEAT)→my own shape commands
Implications for Paju Activist Training
- Works without specialized equipment, using a laptop and a free interpreter
- Runnable in a single 50-minute period anywhere — schools, community venues
- Extends into a cross-curricular experience connecting math, science, and language arts
Notes
- The technology predates 2000, but the mindset (procedural thinking) is the root of today’s coding education
- When activists introduce it as “designing a path in words” rather than “coding = hard,” the entry barrier drops
