Welcome to the CrowLL - Crowdsourcing for language learning game!


Authentic texts are valuable sources for the development of language learning material because they contain language as it is used in real life. This means some texts might include sensitive content, offensive language or language errors. Although such use is unquestionably authentic, teachers and didactic material developers agree that some monitoring is necessary when designing resources in order to make them adequate for their teaching purposes according to characteristics of the students (age, cultural background, level) and lesson's needs (topic). That is why it is good that they (teachers and developers) are aware of the potential problems in advance and have the chance to decide whether they want to include or exclude examples in/from their teaching material.

Having said that, we would like your help to identify problematic sentences retrieved from authentic texts in order to facilitate their use by teachers and material developers of English. Play the game and let us know! 

There are two possible ways to play. You can play game cycles, starting at a level and continuing to the next, or you can play one level at a time, starting at any level you wish.

This crowdsourcing project is an international cooperation between researchers from the Research Centre for General and Applied Linguistics at University of Coimbra (CELGA-ILTEC), in Portugal, the Dutch Language Institute (INT) in Leiden (Netherlands), the Centre for Language Resources and Technologies, University of Ljubljana (CJVT), in Slovenia, Ruppin Academy Centre, in Israel, and the Institute of the Estonian Language (EKI), in Estonia. It originated in the context of the COST action enetCollect (CA16105).

Your responses will be anonymised. No one will be able to identify you or your answers, and no one will know whether or not you have played this game. The data will be kept securely in the server of the University of Coimbra and will be used for research purposes only.

By signing up, you confirm that you have read the above information, agree to data handling policy, voluntarily agree to participate and are 18 years of age or older.
