| The use of e-education platforms as a tool to study the learning process in general chemistry courses is presented. Careful constructions of diagnostic tests lead to the discovery of common mistakes related to chemistry concepts. Comparison of the different questions in course exams with those in the diagnostic tests indicates if misconceptions of the different topics have been overcome. This educational experience allows students to actively participate in the learning process, helping them master those concepts presented in the class sessions. The experience requires the integration of the classroom classes, textbook lectures and practice exercises with the assessment process based on the on-line diagnostic tests. The assessment experiences placed in the Blackboard platform are based in quizzes that contain questions for computer-scoring: multiple choice, matching and numerical problems. For each of these questions, an immediate correction of the questions and feedback based on the most common mistakes detected for the concept examined are provided. Results concerning the type of questions used in diagnostic tests, statistical analysis of the results obtained and the impact of these learning experiences to enhance the concept mastery in the general chemistry course will be presented. |
