Video Tutorials

I know there are a few but they are not categorized on this page... we'll make that happen soon. Help would be appreciated.

• To Square—a tutorial by the Summer Spot youths at the Lilla G. Frederick Pilot Middle School
• a video of the portfolio basics
• Get your hot cold Turtle Art Video here!
• Name that State!
• A Shapes and Colors Game
• A basic tutorial.

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.

• Trigonometry
• The Chomsky_hierarchy of machines and languages
  • Finite state machine/automaton
  • Stack machine or pushdown automaton
  • Bounded linear automaton
  • Turtle Art Turing Machine
• Algebra (Solving equations; structures (groups, rings, fields,...)
• 3D coordinate geometry
• Elementary differential equations
• Electric and magnetic fields
• Algebraic structures
• Statistical analysis
• Models of Molecular Structures; nomenclature
• 3D tilings and crystallographic groups
• Coordinate geometry, Cartesian and Polar
• Conditional probabilities
• Elementary statistics
• The fields of rationals and reals
• Pseudospherical geometry (Lobachevsky)
• Projective geometry
• Geometric optics
• Periodic and Almost-periodic functions (Lissajous figures)
• Moving between Turtle Art and the physical world
