Abstract
The interactive educational digital resources (IEDRs) are more and
more prevalent in all levels of education. With the proliferation of the Internet,
more and more IEDRs are being shared online. How to aid users to explore
helpful resources effectively and efficiently has become a challenge. The static
preview of resources that current research has mainly focused on is ineffective
for the IEDRs, because of the unique feature of the IEDRs that the knowledge is
crucial for the users’ comprehension and is hidden in the process of interaction.
To unfold the hidden crucial knowledge and ensure a users’ fast acquisition, we
proposed a novel approach to generate video previews for the IEDRs, which has
achieved a better visualization of the IEDRs. First, the interactive element set
and the events set, as well as the dependencies between the interactive elements
of the resource are collected. Afterwards, by analyzing the dependencies, the
interaction sequence is generated. Consequently, by automatically executing the
interaction sequence based on the GUI traversal, the manual interaction is
simulated, and the process is recorded into a video. The approach was applied
into a dynamic mathematics educational system, SuperSketchpad, and its
effectiveness was validated by a user study, in which it was compared with the
random event method and event permutation method in correctness,
completeness and redundancy.
