Introduction
to Turtle Blocks
Turtle
Blocks is an activity with a Logo-inspired tool in which a graphical
"turtle" is instructed to draw colorful art based on
snapping together visual programming elements. Basically it allows to
create drawings. Its "low floor" provides an easy entry
point into programming skills for beginners. When a set of
instructions for a virtual turtle to follow is build graphically and
intended output is visualised in movements of the virtual turtle, it
helps in understanding the logical structure of programming. It helps
to detect patterns, understand the repetition of instructions,
visualise the cause and effect and understand the necessity of
conditions while following instructions, which are essential for
computer programming, mathematics, and science. It also has "high
ceiling" programming features which will challenge the more
adventurous student.
Graphical
Interface:
While
opening the new page in Turtle Blocks, “start” block will appear
on the screen. Start
by clicking on (or dragging) blocks from the palette. Use multiple
blocks to create drawings; as the turtle moves under your control,
colorful lines are drawn. To delete a block drag it back onto the
palette. Click anywhere on a "stack" of blocks to start
executing that stack or by clicking in the Rabbit (fast) , Turtle
(slow) or Bug (debug) buttons on the Project Toolbar.
