Structural mechanics courses generally are challenging for engineering technology students. The comprehensive learning process requires retaining knowledge from prior mechanics, materials, and mathematic courses and connecting theoretical concepts to practical applications. The various methods for determining deflections of the beams, especially statically indeterminate beams, are always hard for students to understand and require substantial effort in and out of class. To improve learning efficacy, enhance content understanding, and increase structural learning interest, a laboratory group project focusing on beam deflections has been designed for strength of materials students. The project spans design, analysis, construction, and validation testing of two statically indeterminate bridges of size made of two material types—wood and metal. Students will design their bridges, develop a corresponding spreadsheet based on their design to calculate the expected deflections, construct the bridges, then test their bridges and spreadsheet calculations. A technical experimental project report presenting their design idea, sketches, data analysis, and results discussion is required for each group. Pre- and post-surveys focused on learning efficacy, topic understanding, laboratory experience, and team working will be completed by the students. This paper presents the results of both student surveys and the analysis of the related learning outcomes from examinations. Learning outcome achievement will be compared to those of previous students who did not complete the beam deflection project.
