As same as interview data, at the beginning of this study, there are 73.7% (59 participants/80 participants)
of students who mentioned about “dissolve is the meaning of sugar disappear in water”. However, after
learning on the Web page which the experts selected, a lot of students in this study understood the true meaning
of dissolve. The students pointed out a key virtual animation in the Web page (see Figure 3) which performed
that the sugars disperse in water. That is to say, the students could learn the micro-phenomenon of dissolving
through media or Web-based environment.
S07: The dissolve means disappear… I cannot see the sugar anymore.
S29: I am not sure. I cannot see the sugar in water, but if I put a lot of sugar, it will appear in the bottom of cup.
S63: No! The sugar disappeared after it dissolves in water.
