Rethinking PowerPoint - Deviation from ELD but Worth a Gander at Assertion-Evidence Slides

Assertion-evidence Slides Appear to Lead to Better Comprehension and recall of More Complex Concepts
Kerri Wolf, Penn State & Dr. Joanna K Garner, et al at Old Dominion University asked whether or not assertion-evidence slides are better for communicating technical information. Two groups of students viewed different PPTs with same recorded scripts on MRIs. Researchers then assessed knowledge retention with immediate essays and then tested on their retention of the information two weeks later via a quiz.

Assertion-evidence slides have an assertive statement, a large image, and focused labels via layers. They found A-E slides worked better than the traditional bulleted list which tend to have more text/noise. Use of PPT layers or animation can help students visualize. Over 20% increase in understanding of technical concept was seen with the assertion-evidence slides. Students wrote an essay right after the presentation on the process of MRI. Researchers used a rubric to grade the essays, for the common practice 42% and for assertive-evidence students attained 59%. The common practice students also led to more misconceptions.

These slides do take longer to construct, but worth the time investment! 

Informed Influence: Preparing Graduate Students to Present with Power instead of Just PowerPoint
Christine G. Nicometo & Traci N. Nathans-Kelly from University of Wisconsin, Madison discussed the shift from textual to visual slide design and ability for presented to engage audience or students. They teach in Master of Engineering in Professional Practice, which is primarily on online program, and students have been in industry for at least five years.

Teach students to make assertive statement on their slides along with visuals. They also recommend the use of archival/speaker notes, especially useful when sharing presentations. Their professional students are required to record and view their presentations in order to practice and improve, and they have found the powerful impact of using assertion-evidence based presentation slides.
