The Effectiveness of “Interactive” Slide Presentations for Promoting Student Engagement in University Engineering CoursesInstructors of university engineering classes commonly teach with Microsoft PowerPoint orother slide presentation software. Criticisms of slide-oriented teaching, which is seen asenabling students to be passive participants in the classroom environment, are well-documented (Clark 2008). However, non-traditional slide presentation approaches have notbeen much studied. This paper focuses specifically on “interactive” slide presentations,which are characterized by use of a stylus and a tablet PC to annotate and draw on slidesduring the lecture or classroom discussion. Typically, incomplete (un-annotated) slides areprovided to students in advance of the class.This paper assesses the effectiveness of “interactive” slide presentations for promotingstudent engagement. The methodology employs a classroom protocol adapted from Lane(2010) for quantitatively measuring student engagement in the classroom. In this protocol, atrained observer watches 6-10 students and, during each observation cycle of 1-2 minutes,records the instructional style or classroom activity and rates each student’s engagement,based on visual cues of the student’s actions. A key advantage of this protocol is its emphasison evaluating instructional style and instructor performance through student actions.In this study, a single observer regularly attended three civil engineering courses at a largepublic university in either the Fall, 2012 or Spring, 2013 semesters. The courses included onelarge junior-level required class (~100 students), an elective taken by seniors and first-yeargraduate students (~45 students), and a masters-level graduate course (~ 20 students). Thesecourses are taught by two different tenure-track faculty instructors, both of whom commonlyutilize interactive slide presentations in their teaching. Every two minutes, the observer madenote of the instructional content according to a pre-defined rubric. Categories included“slides writing”, which is characterized by the use of slides that are dominated by instructorannotations, and “slides explaining,” which is characterized by the use of slides that aredominated by previously developed material. Other instructional content categories werestudent work or Q&A. In each of these two-minute increments, the observer also evaluatedsix students, rating each student as actively engaged, passively engaged, disengaged oruncertain. Students were selected randomly for observation at the beginning of each classperiod and the same set of six students monitored throughout. In total, the observer attended15 75-minute class periods for each of three courses, resulting in over 3000 data pointscomparing instructional content and student engagement.The results show large differences in student engagement between “slides writing” and“slides explaining”, with 44% more students being observed as actively engaged. Thesefindings are consistent across the different courses and instructors. In fact, the only otherclassroom activity scoring as high as “slides writing” in terms of student engagement was“student work”, which typically involved small group problem solving activities. In end-of-semester surveys, students gave mixed reviews of the interactive slide presentation method,but all three courses received higher than average scores for the department of civilengineering in university-administered course evaluations. The paper also finds correlationsbetween student engagement, as measured by the classroom observer, and student learning.Selected ReferencesClark, Jennifer. “Powerpoint and Pedagogy: Maintaining Student Interest in UniversityLectures” College Teaching, 56:1, 39-44Lane, Erin, “How does student engagement change with instructional technique” CarlWieman Science Education Initiative, 2010.
