This evidence-based practice paper presents the results of two different one-credit introductory engineering courses: i) a project based and peer assisted learning introductory engineering course focusing on the civil engineering discipline and ii) a seminar course focusing on career planning and design and process improvement theory. The courses were developed to prepare college civil engineering freshman for the rigor of upper level engineering courses by introducing them to various engineering systems, design philosophies, and basic engineering computations. A onecredit first-year introductory course can be utilized by institutions who are limited by state mandated maximum total credit-hours and cost, but still require sufficient student engagement, motivation, and retention. In the project-based course, a special focus is placed on civil engineering systems which includes topics on structural health monitoring, concrete materials, heat of hydration, wind energy harvesting, automobile fuel consumption, vibration and earthquake engineering, and CAD drawing/3D printing. The students are required to complete mini-projects that supplement each of these topics. The projects introduce the students to Microsoft Excel®, PowerPoint®, Pasco®, StaadPro®, and 3D AutoCAD®. The students also learn how to use non-linear solvers for inverse analysis problems, handle large data sets from various sensor outputs, conduct regression analysis, numerically differentiate and integrate, optimize, create technical memos, lab reports, posters, and prepare their resumes. The seminar course focuses on engineering as a career. The course presents topic seminars on career advice, professional organizations, co-op / internships, and a discussion of the different engineering disciplines. The course also covers cross-discipline trendy topics including automation, lean, six sigma and project management. The assignments in this course include building a resume, identifying in-demand skills using job postings, and reading assignments on project management and lean engineering. The grading is based on assignments and attendance. There is a need to evaluate these courses effectiveness in increasing students’ engineering selfefficacy, confidence, and motivation, and justify larger-scale implementation into the engineering curriculum. Students in both courses were given a 40 item preand postonline survey to assess their engineering design confidence and motivation, and self-efficacy in engineering skills, technical ability, design, and tinkering, teamwork skills, and their career awareness. Significant gains in the pre/post populations were evaluated using the nonparametric Mann-Whitney U test. The results indicate the students in the project-based course show significant gains in engineering design confidence and skills, and have statistically significant higher postengineering design confidence, motivation, tinkering skills, and engineering skills. The students’ in the career-based course show significant gains in engineering design confidence and career awareness.
