This study compared student engagement and performance in both open educational resources (OER) (n[open textbook users fall 2018] = 72) and traditional textbook (n[traditional textbook users fall 2017] = 66) classes. Data were drawn from the Learning Management System (LMS). Results show (1) final grades in the OER class were on a par with the traditional textbook class, and (2) OER equalize student engagement and performance by narrowing the dispersions of page views, on-time assignment submissions (OTAS), attendance, and final grades. (3) OER increased attendance and lessened excessive dependence on LMS course materials recorded in the traditional class. (4) The indirect effect of attendance on final grades was stronger than the direct effect of OTAS in the OER class. Attendance provided the opportunity for the instructor and students to be on the “same page,” which helps students better assimilate course content and comprehend lectures. (5) The availability of textbooks appears to be a factor influencing student course success. However, it remains unknown how much of the variance was explained by OER. It is apparent that OER are more important than ever in elevating overall student academic success.

Structural Analysis by Felix Udeyo is intended to teach students the methods and techniques for the analysis of structures. A sound knowledge of structures is a prerequisite for their proper design and ensures the structural integrity of civil engineering infrastructural systems. This textbook is comprised of three parts. The first part consists of an overview of structural analysis and introduces several structural loadings that may be considered during the analysis and subsequent design of structures. The second part covers classic methods of the analysis of determinate structures. The final section discusses classic methods for the analysis of indeterminate structures as well as methods for the analysis and construction of influence lines for indeterminate structures.
