We illustrate the call-as-event pattern for helping users to use Event B. As teacher, we are using students to evaluate our methodology and we give comments in italic, when we have got reactions from our students: a given definition, a concept related to our methodology, for instance. We discuss points related to our lectures at different levels of the university, mainly master. Simple case studies illustrate the teaching methodology based on interactive proofs.<\/jats:p>","DOI":"10.1145\/1595453.1595462","type":"journal-article","created":{"date-parts":[[2009,8,24]],"date-time":"2009-08-24T14:08:31Z","timestamp":1251122911000},"page":"51-59","update-policy":"http:\/\/dx.doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["A simple refinement-based method for constructing algorithms"],"prefix":"10.1145","volume":"41","author":[{"given":"Dominique","family":"M\u00e9ry","sequence":"first","affiliation":[{"name":"Universit\u00e9 Henri Poincar\u00e9 Nancy 1, Vandoeuvre-l\u00e8s-Nancy, France"}]}],"member":"320","published-online":{"date-parts":[[2009,6,25]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"crossref","DOI":"10.1017\/CBO9780511624162","volume-title":"The B book - Assigning Programs to Meanings","author":"Abrial J.-R.","year":"1996","unstructured":"Abrial , J.-R.
