I found this web page interesting and useful as one can find lots of information about listening, speaking and writing skills at academic level. Also there are several developing activities which are very applicable.
As we are future teachers I think this information can be very useful,because we always need a bunch of activities to conduct a lesson and to keep the whole class motivated.
In my opinion this site is very useful for ESL teachers to suggest to their learners and to use as a source of material. It contains not only grammar material or vocabulary, but also has pages which make the learning process intersting and provide learners with intellectual information.
