It seems that you are not alone in your interest in woodlouse behavior:

See the question starting with "I am studying the behavior...". According to this web page, high school (?) students who have done memory experiments using mazes did not observe evidence of what we tend to think of as 'learned' behavior. However, interesting to note, new sow bugs seemed to be able to navigate the mazes as well as the ones that had already navigated the maze, suggesting a scent trail left by earlier bugs. You could do some interesting experiments based on behavior related to scent trails.
That web page seems to be a good resource for your work:

Here is an abstract of a peer-reviewed article that is relevant to your work and might help to convince judges that you would be conducting serious, scientifically relevant research:
Title: Questions and possible new directions for research into the biology of terrestrial isopods
Author(s): Hassall M, Zimmer M, Loureiro S
Source: EUROPEAN JOURNAL OF SOIL BIOLOGY 41 (3-4): 57-61 JUL-DEC 2005
Abstract: New directions for research identified during the final plenary discussion of the Sixth Symposium on the Biology of Terrestrial Isopods included: locating enzymes buffering pleon fluids during excretion of ammonia and the use of isopods in ecotoxicology including how they adapt to or tolerate high contaminant levels; how they interact with free living and endosymbiotic microbiota and how Wolbacchia avoids the immune response of isopods. New analyses of mating behaviour raised questions concerning mate choice while new microsatellite techniques may help resolve issues of multiple paternity and sperm competition. In relation to their ecology and biogeography new questions included how does the ability to learn the location of high quality food patches in spatially heterogeneous environments and the existence of an Allee effect, influence the population biology of isopods in the field and how do patterns of invasion and colonisation vary between species with different motility and life history strategies?
Here is text from that article listing some relevant research questions related to behavior:
"Do isopods learn to relocate high quality food patches in
the field as they do in the laboratory ?What is the range
of daily foraging movements and how are these affected by
weather conditions ? Does the increased activity of isopods
in late spring  relate to courtship and mate finding
behaviour ? Does increased activity in autumn  represent
lateral seasonal migration to more favourable wintering
areas? Could directional pitfall trapping  be used to determine
differences in directional movements at different times
of year? How common are mass migrations in isopods ?
Are they related to changes in meteorological conditions or
resource distribution? Are they directional or are they random
Here is the reference #36, listed above, that seems to relate to your interest in woodlouse learning/ memory:
Title: Locating food in a spatially heterogeneous environment: Implications for fitness of the macrodecomposer Armadillidium vulgare (Isopoda : Oniscidea)
Author(s): Tuck JM, Hassall M
Source: BEHAVIORAL ECOLOGY AND SOCIOBIOLOGY 58 (6): 545-551 OCT 2005
Abstract: To assess the fitness consequences of foraging on patchy resources, consumption rates, growth rates and survivorship of Armadillidium vulgare were monitored while feeding in arenas in which the spatial distribution of patches of high quality food (powdered dicotyledonous leaf litter) was varied within a matrix of low quality food (powdered grass leaf litter). Predictions from behavioural experiments that these fitness correlates would be lower when high quality food is more heterogeneously distributed in space were tested but not supported either by laboratory or field experiments. To investigate whether A. vulgare can develop the ability to relocate high quality food patches, changes in foraging behaviour, over a comparable time period to that used in the fitness experiments, were monitored in arenas in which there was a high quality food patch in a low quality matrix. A. vulgare increased its ability to relocate the position of high quality food over time. It reduced time spent in low quality food matrices and increased time spent in high quality food patches with time after the start of the experiment. When the position of a high quality food patch was moved, the time spent in the low quality food matrix increased and less time was spent in high quality food patches, compared to arenas in which the food was not moved. The fitness benefits for saprophages of developing the ability to relocate high quality patches while foraging in spatially heterogeneous environments are discussed.
