Summary: Background estatus is a webbased tool able to generate different statistical exercises and to provide immediate feedback to students' answers. Although the use of Information and Communication Technologies (ICTs) is becoming widespread in undergraduate education, there are few experimental studies evaluating its effects on learning. Method All of the students (121) from an introductory course for statistics in dentistry were randomly assigned to use the tool with one of two 6problem sets, known as types A and B. The primary endpoint was the grade difference obtained in the final exam, composed of two blocks of questions related to types A and B. The exam evaluator was masked to the intervention group. Results We found that the effect of estatus on the student grade was an improvement of 0.48 points (95\% Cl: 0.100.86) on a tenpoint scale. Among the 94 students who actually employed estatus, the effect size was 0.63 (95\% Cl: 0.171.10). Conclusions It is feasible to formally assess the learning effect of an innovative tool. Providing estatus exercises to students has a direct effect on learning numerical operations related to statistics. Further effects on higher cognitive levels still have to be explored.
