Mokurai's Tutorials

Mokurai has been working on how to teach Sugar by guided discovery, rather than by explicit direction, with only the necessary minimum of hints. At the same time, he has been working on Turtle Art examples to teach concepts of mathematics, programming, Computer Science, and physics, aiming where possible at presentations suitable for pre-literate pre-schoolers. Thus, no text, no formulas, no calculations. Those can come later in sequences on the same topics as children develop, including a transition from Turtle Art to Python, Logo, and Smalltalk, with options for other languages. However, it is necessary to provide texts, sometimes with formulas and calculations, for the teacher or parent helping the child. These will appear on Mokurai's Replacing Textbooks blog, available at PlanetSugarlabs, and will be incorporated into Open Education Resources on the Sugar Labs Replacing Textbooks server.

Higher

At this level it is not necessary to use Turtle Art to introduce ideas. Nevertheless the ability to display a topic in Turtle Art demonstrates that it is of only a moderate level of complexity.

• The Chomsky hierarchy of machines and languages
  • Finite state machine/automaton
  • Stack machine or pushdown automaton
  • Bounded linear automaton
  • Turtle Art Turing Machine
• Algebra
• Trigonometry
• 3D coordinate geometry
• Elementary differential equations
• Electric and magnetic fields
• Algebraic structures
• Statistical analysis
