Gender Agents has been used as a motivational strategy to invite females and ethnic minority students (Kim & Wei, 2011; Kim, Wei, Xu, & Ko, 2007) Social biases and gender-related stereotypes are often replicated in learner-agent interactions (Haake & Gulz, 2008) Abuse Visual appearance Social interactions have potential benefits eg., promoting learner motivation and increasing learning A study revealed(de Angeli& Brahnam, 2005): approximately 11% of the conversations were concerned with hardcore sex the female agent suffered considerably more abuse than the male counterpart or the agent depicted as a robot 2
Abuse Results Abuse The chatlogswere annotated using the following coding schema*: 1. Light abuse: noob, nerd, shut up, don t care, ugly, shit, etc. 2. Medium abuse: gay/fag, stupid, idiot, moron, eat shit, creep, etc. 3. Coarse abuse: degrading expressions with swear words and/or sexual content. * Translated from Swedish. Swedish teenagers have been involved in the construction of this classification scheme Results Abuse Male participants were by far more responsible for abusive comments (two-tailed t-test on Abuse p < 0.001) No coarse abuse from the female participants Results Androgyny 0,45 0,4 0,35 0,3 0,25 0,2 0,15 0,1 0,05 0 Asked gender Female Androgynous Male Very few students asked the visually androgynous agent whether it was a boy or a girl, whereas significantly more (one-tailed t-test: p = 0.042) students posed this question to the male and female agent Participants did not ask for the agent s gender if it had the same visual gender as themselves Conclusions These results suggest that androgyny may be a way to keep both genders represented, which is especially important in pedagogical settings, simultaneously lowering the abusive behavior and perhaps most important, loosen the connection between gender and abuse 3

Hur ser elever på sina val och situationen då det inte går framåt? Kommer skillnader att variera med studentens kön, kunskapsnivå, målorientering? Hur skiljer sig LBT från LFO? 4
