How I Use It
As a Technology Resource Teacher we use Khan as a supplemental math program for some of the grades in our district. I have noticed that for our more advanced math students they seem to strive to complete lessons, earn badges, and master concepts. I worked with the students on how to start and took them through the interface in an introductory lesson for Khan Academy and then they took of on their own. The most difficult part is the parent email piece in order to change students passwords if needed but based on safety and security it is understandable to why this is needed.
My take is that I love it. We use it as low as 3rd grade for math but I tend not to go any lower than that grade level when introducing it. From a system administration stand point for a district to use it is kind of a pain since there are no upload options available for mass registration of students. Also, we stay away from under grade 3 due to the fact that there is something funky when using the text-to-speech options either in Google Chrome or using the OS text-to-speech as when it reads numbers it will read them 3 times. For example, if the question is "Stan was driving 30 miles per hour. How long will it take him to drive 60 miles?" It will say "Stan is driving 30,3030 miles per hour. How long will it take him to drive 60,6060 miles?".
In 3rd and 4th grade when we begin using it though the students love it, especially since it is a tool where they can go and work at their own pace. It is difficult for teachers to differentiate lessons for each individual students and meet them where they are when teaching a whole-class designed curriculum. With Khan Academy the students are able to work on their own for what they need and the teacher can see all of it through their dashboard, even down to the exact minute the student was working on a skill.
Overall, I love it. Some of the setup is a pain to begin but if you have someone willing to do it that believes in the benefits of the program it is worth it.
