Project-based learning as a strategy for teaching metrology

Project-based learning (PBL) is a well-known didactic strategy to improve students' understanding of science, as well as their problem-solving and collaboration skills, to a greater extent than traditional methods. Students who learn science or technology through project-based learning also report that they find it more engaging than traditional instructional techniques. PBL strategy was applied to students of engineering degree in industrial metrology taught at the Universidad Politécnica de Santa Rosa Jáuregui located in the state of Querétaro, Mexico. This paper describes the experience through which students planned, implemented, and evaluated a project with real-world application beyond the classroom, which leads to a drive for research and production of knowledge. Professors of different subjects worked together to think about the project. In this case the selected integrating project was the design and performance evaluation of a bio filter for the treatment of gray water in rural households. This project includes concepts related to the subjects taught in the period of study. The subjects considered were: Analytical chemistry, industrial processes, statistics, mathematics, engineering drawing, interpersonal development and English. The use of this strategy helped to promote student participation in the learning process. Results were very satisfactory because of the knowledge and skills acquired by students. This allowed the development of new capabilities that complement their education and prepare them for the workplace. Among the skills and capabilities developed are: interaction in teamwork, independent learning, responsibility and time management, among others.
