The Metiri Group's report disputes the widely debated Cone of Experience theory, which says each of us learns 10 percent of what we read, 20 percent of what we hear, 30 percent of what we see, 50 percent of what we hear and see, 70 percent of what we say or write, and 90 percent of what we say as we do a thing. (The rampant misrepresentation of researcher Edgar Dale's valid model of classifying learning styles is discussed in this entry in the blog of educational consultant Will Thalheimer.) After an extensive search, the report's authors were unable to find any empirical evidence supporting this breakdown. Contrary to popular opinion, research shows that lessons in which students interact with material, rather than passively absorb it, are not always better.
Jeff Johnson on 22 Jul 08What I am learning from my school's infatuation with computers When I first learned that all of my students were getting laptops, I thought it was an educator's dream come true. One year later, I look at the situation differently. Like many progressive educators, I have regarded computers and other technology in schools as important tools to help students understand the world around them. I also hoped that providing all students with laptops would address the digital divide. But after an exhausting year, I have learned that before adopting the technology on a wide scale, it is essential for schools to first consider the potential promises and perils of using technology in the classroom. I believe that social justice educators must ask ourselves and our schools: What are the ethics and power structures involved in using a technology, and how do we create a learning environment to discuss and track the impact of technology on the cognitive, social and emotional development of both students and educators.
