The article presents a comparative analysis of learning a group of students in three different courses in the classroom mode or 'campus', and distance or 'online' using synchronous technology through web-conferencing software. The findings establish a very good perception on the part of students, who qualify very well these tools, and on the other hand, the average rating of distance learning is superior in two of the three courses to the classroom course. A questionnaire was designed to address issues concerning the adequacy of the tools in online courses to make learning efficient and secondly, to check the learning performance of students in both modes. Result: It has obtained sufficient information to analyze in depth courses and establish conclusions on the adequacy of the means used to distance and comparative results on respect to traditional teaching. Discussion & Conclusion: It has been found that there is a very good perception of students who qualify very well these tools and the results of student grades on-line exceed on average than those obtained in the classroom course
