In this task, students will be asked to use the Pen tool in Scratch to draw a square. Once they have figured out how to draw it one way, they will try to find different coding blocks that produce the same square. The task will encourage students to use creativity and problem solving ...
I have seen a few internet videos that teach how to draw a perfect cube in a two-point perspective. However, the methods they show are rather complex. I prefer not to use them every time I try to draw a simple square. I also do not like the fact that these methods only cover a t...
The treemap (rectangular tree map) was first proposed by the American computer scientistBen Shneidermanin 1992. In order to deal with the common hard disk full problem, Ben Shneiderman innovatively proposed the idea of generating a visualized directory tree structure. This form of display even has...
