Flipped classroom-comparative case study in engineering higher education

摘要

The use of flipped-classroom methodology (FC) has increased recently, however, there is a lack of quantitative data on students' performance. A FC has been applied into a group (80 students) of an obligatory subject of the 2nd course in an Energetic Engineering Bachelor. A second group has been taught with the traditional methodology (72 students) to compare the results. The FC requires students to obtain background knowledge prior to a face-to face class meeting, and reserves in-class time for applying knowledge to solve problems. This is the opposite of the traditional lecture-based classroom, in which students passively attend didactic lectures from the instructor, then study the content and complete assignments after class. The main objectives of this research were to measure the impact of learning (with special attention to really active students), reduce absenteeism, increase exam attendance, and analyze how participating students view their experience with this methodology. The results show that the flipped-classroom model has a direct impact on student learning (or grades), especially in students with a high degree of involvement (with grades about 1.5 points higher). In addition, the grades standard deviation values were lower (in about one point), ensuring a better general students level. The students are a little reluctant to this new methodology, but thanks to it, they tend to work more (12% of the students work more hours per week), to attend more to class (at least 10% more), and to attend in a higher ratio to exams (around 20%).
