Barry Desborough, France

Barry Ludvik, Sheboygan Falls, WI
Educational Technology Specialist, Sheboygan Falls School Distirct Barry was a life sciences teacher for 23 years. During those years he was, as we all are, posed with the question “Why do I need to know this?” and it really made him wonder. He came to the conclusion that his students didn’t need to know the content necessarily, but needed the content to become better thinkers. His focus changed to developing thinking skills and having the students become creators that had ownership in their learning. This is why he turned to FlexBooks — because the students and the teacher could modify and create a book that would meet their specific needs. He is currently in the tech department now and encourages others to do the same.
