|Abstract or Summary
- The rapid development of computing technologies in recent decades has allowed for data to be
generated at unprecedented rates. As a result, users are challenged with the task of finding the
precise information that they are looking for. Visualization techniques provide the ability to view
and analyze data in different ways, helping users to find what they are looking for and gain
additional insights. TeachEngineering is a digital library system where K-12 educators can search
for high-quality lesson plans that meet national and state-specific educational standards. Users
have several different types of criteria to search by, including: grade level, cost, time required,
group size, keywords, source state, and educational standards. Being able to see how individual
documents compare to specific variables can help identify additional results that are worthy of
user consideration. Surveying visualization techniques, specific methods (scatterplots, parallel
coordinates, star glyphs and hyperbolic trees) are qualitatively analyzed with regards to how they
could be applied to TeachEngineering search query results. Each visualization type has
advantages and limitations, and no single technique can be considered the definitive solution.
Recommendations on conducting future experiments and research are included.
