The objective of this project is to present a webbased tool which will allow the student to solve an exercise as many times as needed, and always with new data. Students usually see exercises as an essential part of their education. Exercises are undoubtedly a good complement for the "theoretical" lessons: they show how the concepts explained in the classroom are applied in real or simplified cases, and they make easier the comprehension of the exposed ideas, through a typical process of learning by doing (the inductive way). The tool estatus will give the answer to each question by request. Several parameters such as date, problem identifier, number of errors, number of correct answers, time consumed, etc, will be collected and stored in the Students Database, so that this information will be available, not only for consideration of the instructor, but also to provide feedback to the students. Moreover, checks for students' progress will be easily implemented. An exercise will be specified in this way: a) several statements describing the problem, b) a set of arithmetic formulae, each one with its corresponding symbol, c) the available data, d) the questions, each one containing one statement and the answer (some symbol previously defined). At this moment this software is being developed for an introductory course of probability and statistical inference, taught to 2nd year students of Computer Sciences Engineering. Some problem data can be defined as random by the author of the exercise, therefore the tool will be useful to pose any statistical problem in the scope of our courses. The student obtains practice to model diverse situations by means of a (sufficient) number of different exercises, whereas the repetition of the exercise involves the habit of the computation and better understanding of the application of the main concepts. The proposed methodology can be useful to many other courses on a mathematical basis, mainly in engineering studies, whose students make extensive use of problem solving in order to lessen the level of abstraction present in the classroom.
