This past summer our district installed Promethean Boards in all the math classrooms (10 rooms). In addition, our school received 4 sets of ActivExpression Classroom Response systems (32 untis in a set). These units are handheld devices that each student uses wirelessly at their desk. They can input numerical answers, choose multiple choice answers, text in 140 characters, choose "yes" or "no" or "true" or "false" and also use a Likert scale. When we first received these devices, I did not use them. I was too overwhelmed with using the Promethean Board itself.
However, after the 1st trimester ended I decided I would implement the response system into my classes. I thought that if I waited until I developed the perfect lesson to use these devices, I would never get around to using them. So, I forced myself to pass them out on day 1 of the new trimester and implement this technology into my daily lessons. Whenever I present concepts to students I am constantly asking questions and trying to draw out the student's thought process and feedback. Now, with these devices, ALL students can actively input their response to my questions. Once the students respond I can display a quick bar graph of their results. Thus, I can easily check if students are understanding the concepts. It is a fabulous tool for involving all students and for checking student understanding. The students have really enjoyed the devices and they are so much more actively involved in the lessons.
There is so much new technology for teachers and students to use. I wonder what other teachers are using in their classrooms to help students learn mathematics New technology, old technology, new web pages, old web resources, other manipulates...?
