The ACRL information literacy standards include the need for students to use information effectively to accomplish a specific purpose. To use information for a specific purpose students should have an ability to differentiate the types of information available, assess the relevance and credibility of the source to their application, and then apply the information within the context of their writing. Engineering students are usually aware of monographs and periodicals from introductory library instruction but are unfamiliar with grey literature and engineering standards. To address this need, collaboration between library and engineering instruction for a senior level capstone mechanical engineering design course was created. The course consisted of 3 independent sections of approximately 18 students each that were randomly paired and assigned projects from the same pool of 10 system-level experiments. The students were tasked with developing a full analysis and report of the system-level performance of their respective experiment. Library instruction occurred during the second lecture of class and consisted of a fifty minute overview presentation followed by two hours of work time. All sections were presented information types as five different categories: monographs, scholarly articles, grey literature, standards, and multimedia. One section of the class was randomly selected and presented information types placed into contextual uses within example sections of a report and assigned a worksheet requiring them to find sources specific to their project and list them within the report section they planned to implement the literature. The efficacy of this pedagogical change to contextualize examples followed by immediate application was assessed by measuring the frequency and type of citations used by all 3 sections of the class. Citation analysis found a statistically insignificant 7% increase in total number of citations used by the test section students. Although the utilization of engineering standards did not increase, the use of grey literature in the test section increase 83% compared with the two control sections taught by the same engineering faculty. Furthermore the test section decreased their use of multimedia information. Two subsequent sections of the course taught by other engineering faculty are also compared. This provides a preliminary indication that contextualizing library instruction by information type increases the diversity of literature utilized by engineering students. The overall credibility of citations utilized by students in their reports is likely to increase if this diversity increases the use of grey literature and standards.
