The analysis of students’ questions can be used to improve the learning experience for both students and teacher. We investigated questions (N = 6457) asked before the class by 1st year medicine/pharmacy students on an online platform, used by professors to prepare their on-site Q&A session. Our long-term objectives are to help professors in categorizing those questions, and to provide students with feedback on the quality of their questions. To do so, first we developed a taxonomy of questions then used for an automatic annotation of the whole corpus. We identified students’ characteristics from the typology of questions they asked using K-Means algorithm over four courses. The students were clustered based on the question dimensions only. Then, we characterised the clusters by attributes not used for clustering such as the students’ grade, the attendance, the number and popularity of questions asked. Two similar clusters always appeared (lower than average students with popular questions, and higher than average students with unpopular questions). We replicated these analyses on the same courses across different years to show the possibility to predict students’ profiles online. This work shows the usefulness and the validity of our taxonomy and the relevance of this approach to identify different students’ profiles.

Falar do longo processo de mobilização nacional pela reforma do código da família no Marrocos exige que se preste homenagem aos primeiros militantes, homens e mulheres, pela emancipação das mulheres. Desde os anos quarenta, esses pioneiros colocavam entre suas reivindicações a abolição da poligamia, o estabelecimento do divórcio judiciário e os direitos iguais para as mulheres no interior da família. Os líderes do movimento de reforma Salafiya no Marrocos, entre eles Allal el-Fassi, estiveram entre seus inspiradores. De fato, a evolução da condição das mulheres marroquinas no início do século XX deu-se sob a dupla influência, por um lado, das novas condições sócio-econômicas e culturais resultantes da colonização e, por outro lado, através das idéias-chaves do reformismo muçulmano (Salafiya), difundidas pelos movimentos nacionalistas nas quais se inspiravam. Este ensaio é um convite para que se conheça a contribuição desta corrente e, em particular, a contribuição de seu líder, Allal el-Fassi, à evolução da sociedade marroquina moderna e à ascensão das mulheres marroquinas durante a primeira metade do século XX.
Going beyond mere forum posts categorization is key to understand why some students struggle and eventually fail in MOOCs. We propose here an extension of a coding scheme and present the design of the associated automatic annotation tools to tag students' questions in their forum posts. Working of four sessions of the same MOOC, we cluster students' questions and show how the obtained clusters are consistent across all sessions and can be sometimes correlated with students' success in the MOOC. Moreover, it helps us better understand the nature of questions asked by successful vs. unsuccessful students.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
