Bridge Design Project: A Hands-On Approach to Statics and Strength of Materials Learning
An obstacle for Manufacturing Engineering Technology (MET) students who are trying to learn Statics and Strength of Materials is their lack of involvement in their learning process. These students sit passively as instructors demonstrate concepts or, when solving the problems, are not active learners. In order to avoid this behavior, a bridge design project offers an interactive approach to engage students in the learning process. This paper provides some of the guidelines of a bridge design project that can be useful in active learning. Several project management skills are also integrated throughout the project. This paper describes our experience in developing the bridge design project.
Research has shown that project-based learning is an exceptionally effective learning activity. Many university professors today accept this learning environment to transform passive learning into active learning in their classrooms . In order to find better ways of involving students in their learning process, we introduced the Bridge Design Project into our MET 322 Statics, Dynamics, and Mechanics of Materials course. With this bridge design project, students learn more material, retain the information longer, and enjoy the class activities more. The bridge design project allows students to explore many statics topics in the classroom with the help of the instructor and other classmates, rather than on their own.
The bridge design project is one of active learning techniques used in this course to encourage students do more than simply listen to a lecture. They are building a bridge to prove their ideas and to demonstrate what they have learned from the course. After researching, processing, and applying information from websites, simulation software, and field trips, students are ready to share their ideas with team members. After dividing the students into teams (5 students/per team) and assign each a different role, they must work to design, construct, and test their team’s bridge.
In order to make the bridge design project realistic, students have to practice project management skills and learn how to allocate and control the following resources: (1) $25,000 budget (2) construction time – 4 hours, and (3) building materials – straws, hot glues... etc.
Overview of Statics, and Strength of Materials Course Many Manufacturing Engineering Technology (MET) curricula include both statics and strength of materials courses. These courses typically focus on different force systems and analysis of structures, which often involve a lot of formulas and theoretical concepts. The bridge design project attempts to provide student opportunities to practice their statics and strength of materials knowledge by designing, building, and testing a bridge based on the course concepts. At present, about 80 students at Minnesota State University (MSU), Mankato are involved with the project every year. All of the students are given a good foundational of concepts, principles and
