We think our products are great! But don't just take our word for it, here's what teachers have to say...

"I was first introduced to Logo about 20 years ago at the University of Nebraska. About 10 years ago when the opportunity came up to teach a 6-week exploratory class for seventh graders, I knew right away that I wanted to use MicroWorlds! Now that MicroWorlds EX is out, the students are not only experiencing computer programming at their level of expertise, but I firmly believe that MicroWorlds builds a strong foundation towards a future computer science career."

Tom J. Price Norris Middle School Firth, Nebraska

"Here at Shabonee School, we have developed a math curriculum based entirely on MicroWorlds EX (...) The program provides students with the opportunity to investigate geometric concepts through the use of Logo computer language. In addition, students use and strengthen their logical thinking, problem solving, and other higher order thinking skills."

"Our experience with MicroWorlds EX is very positive and many of our students use the program for fun on their home computers."

"MicroWorlds EX is one of our core tool programs. Because of Logo's inherent mathematical structure, Logo activities are integrated into the math curriculum to teach important geometry concepts such as units of measurement, angles, scale, and shapes. Microworlds EX is a multipurpose tool program that provides an environment for children to work collaboratively and independently to develop problem solving skills."
