Yesterday my students were using laptops along with a program called IXL, an online version of computer-assisted instruction. I wrote my senior thesis in college on these types of programs back in 2007 and am excited to see how they have developed. Students are provided with a set of problems based on the topic of their choosing (in this case, determining the slope of a line from a graph) and then as they get answers correct the difficulty level also increases. When they get an answer incorrect, an explanation is shown to help them learn and move on. Our students find this really helpful and once they believe the feedback is useful (that's the biggest challenge) they can use the tool to learn. It went well.
I am a math teacher in the New York Department of Education. I infuse technology and real-world problems into my curriculum in order to prepare my students for the future. I would love for people across the country to recognize we teachers can't do it alone. If you don't believe me, come visit my classroom!
