In Fig. 1 we can see that the percentage of students passing the course is higher in the 5 years where the Competition-based Learning approach has been used (96.56% in average) than in the other 5 years without CnBL (90% in average). Besides, all the courses where CnBL has been applied have better results than all the courses when it has not, with an exception in the year 2002. Fig. 2 shows the average mark obtained by the students along the courses. Here it is clear how the average mark obtained using competitions (8.6 over 10) is higher than the average mark obtained without it (7.8 over 10).We also see how the average marks in the years where CnBL was applied is higher than when it was not, only 2003 has a similar average mark than 2002 and 2001. Finally, Table 10 summarizes the data used in this section. The previous figures and data suggest an improvement in the students' performance, in those courses where the CnBL approach has been used. Nevertheless, considering the novelty of these empirical results, it is important to remark here that it does not mean that CnBL is better than to any other learning technique. Instead, it points out about its interest as a complementary technique for enhancing the learning experience, and for stimulating the students’ motivation.
