Multimedia Project 1: Child Labor in America

Below is a Google Presentation on Child Labor in America. It uses historical images to guide the student through the world of working children in the early 20th century. Images and narration will allow students to understand the types of jobs that kids held, the short and long term negative impacts of the jobs, the reasons why kids held these jobs and help them to predict the types of changes that the country would make to end chid labor. The lesson would serve as an introduction to the progressive reforms of the early 1900s.

I made sure to use lots of large, but simple images to go along with the narration. For most of the presentation, there is only narration and not accompanying text. Research from Clark and Mayer (2011) indicates that when there is text and narration at the same time, student learning is reduced. While it seems to make sense to include redundant text with all narration, research indicates that it is not an evidence based media strategy. If we relate it to what we know about cognitive learning theories, we can understand the brain works like a highway. Text and narration both enter the brain through the same road. If we overload that road, we create a mental traffic jam and learning becomes inefficient.
