• Stage E: Summary
In the summary of this activity, it is important to highlight that visual-
ization and animation have the potential to promote computer science
learning from several reasons. First, visualization and animation support
very naturally active learning; second, they enable learners to concretize
abstract concepts; and finally, learners may conceive visualization and
animation as a kind of a game (see Chap. 7), and therefore their use may
increase the learners' interest in computer science.
• Stage F: Homework
−
Option 1
: The students work at home on the following activities, which
offer them an additional opportunity to rethink the different usages
of visualization and animation in the context of computer science
education.
− Develop the second kind of worksheet than the one you developed
in the class—the worksheet is given to learners either before or after
they learn the said computer science topic (see Stage B).
− Formulate guidelines for the development of a worksheet that is
based on learners' engagement with algorithm/program animation/
visualization. Reflect: What considerations guided you in the formu-
lation of these guidelines?
−
Option 2
: Explore the algorithm visualization portal.

Activity 65: Musical Debugging
Music is one aspect of visualization and can be used in computer science edu-
cation in several ways. For example, this musical debugging activity (Lapidot
and Hazzan
2005
) increases learners' awareness to their debugging processes,
the importance of debugging, and its relationship to learning processes. It also
