Xiaomei Gong and Mary Kay Loomis of Western Connecticut State University have written a nice article titled An Empirical Study on Follow-up Library Instruction Sessions in the Classroom. It was published in the Electronic Journal of Academic and Special Librarianship.
From the abstract:
This study with undergraduate students in the Ancell School of Business, Western Connecticut State University, evaluated the knowledge of students using library resources before and after one session of library instruction in the library, and after follow-up instruction in the classroom. Survey method was used before and after the initial session of library instruction in the library, and after follow-up instruction session in the classroom. Significant differences were found in the students’ knowledge of library resources between the pre- and post- surveys in the library session and in the library usage experience after the follow-up instruction session in the classroom. The study also enhanced librarians’ techniques for teaching the millennial generation to effectively use library resources.
