New submission from Bruce Fuda :
Since Python is being taught to students of all ages and in particular younger
kids (i.e. 6 - 10 yo) who are learning not just python, but many related things
for the first time, the need to include values as arguments to basic Turtle
functions like:
forward()
backward()
left()
right()
adds additional complexity. The natural starting point for these types of
activities with kids is a transition from the physical world of devices such as
the Bee-bot
(https://www.tts-international.com/bee-bot-programmable-floor-robot/1015268.html)
which have pre-defined lengths (i.e. 15cm) and turn angles (i.e. 90 degrees)
so that they can focus primarily on sequencing and learning commands without
the cognitive load of additional information.
It would be an ideal starting point for the forward(), backward(), left() and
right() commands to be overloaded such that there is a default value. This
reduces the cognitive load for young students, because it instead means they
can focus on learning basic commands, sequencing and syntax without also
needing to understand angles and relative lengths.
Suggestion would be to set a default value for movement (i.e. forward and
backward) of 50, and default angles for turning (left and right) of 90 degrees.
This simple (and trivial) change would massively help thousands of students get
started with Python, without in any way impacting existing use of Turtle.
