The use of analogies is a cognitive strategy frequently adopted by learners when they want to understand some new concept. In that case, the analogy connects the new concept with the previous knowledge, attaching it in the learner cognitive structure. Some studies points out the use of analogies and previous knowledge of learners increases the learning material quality, stimulating the learners to use their cognitive strategies. Nevertheless, there are no studies about a way to enable both the use of analogies and learners previous knowledge to facilitate continued learning, mainly taking into account computational support for e-leaning. In this work it is presented a prototype of an on-line assistant to support a training course about workspace safety issues. The application uses a common sense reasoning engine and the Brazilian Open Mind common sense knowledge base, to make inferences about concepts that might be unfamiliar to the students. It is explored the use of analogies to explain topics, enhancing learning by using context capture to help students associate related topics. It is believed that common sense can be used to take into account cultural considerations while helping learners to build analogies. It is also explored the suggestion of analogies, which were build using commonsense knowledge, to the teachers during the project of instructional material design. Preliminary results with students using the assistant point that they considered analogies useful in the learning process, that the system is helpful in understanding new concepts, and that it helps connect the information searched for with common sense knowledge.
