This document provides a research proposal that examines the impact of static (PowerPoint) versus interactive (VoiceThread) presentations on student achievement in an online US history course. The researchers will teach two sections of the course using either PowerPoint lectures or VoiceThread enhanced lectures. Students will complete pre- and post-questionnaires on satisfaction and motivation, and take a final exam to assess achievement. The study aims to determine if interactive courseware leads to increases in student satisfaction, motivation, and achievement compared to static presentations.
