Meaningful and effective feedback is a critical issue for a real development of new competences in technical careers. Traditionally, they have been provided in asynchronous form and expressed as a numeric mark. However, many studies indicate that information and guidelines given during this process become more effective as the delayed time between exercise execution and feedback decreases. This fact is especially relevant for modern Graphic Expression courses, in which development of technical abilities in CAD are provoking a significant increase on the number of tasks requiring to be evaluated. The present work analyzes the benefits of meaningful and timely feedback used for laboratory practices with AutoCAD in Graphic Expression. The proposed methodology is applied on weekly sessions with a duration of 2 h per session in which the class is divided into two groups, reaching a ratio of around 15–20 students/professor. The proposed practice cases are evaluated timely just in the computer room, taking only a few minutes at the end of each session. The instructors check concrete aspects for each case accordingly to a very simple rubric, providing an immediate feedback to the students. Thus, they are aware of their own faults just-in-time, being possible to take concrete measures to advance in a deep knowledge. Results evidence a significant improvement in developing CAD competences as comparing to previous courses in which a traditional delayed feedback was used. Additionally, despite the required time to prepare meaningful exercises, the proposed methodology also prevents an excessive work overload for professors during conventional evaluation periods.
