Greenhaus Education and Other "Effects"

In yesterday's weekly #edchat Twitter collaboration the discussion focused on the flipped classroom, where, naturally, there was quite a bit of debate around the idea of video lectures. What became apparent was the many different interpretations of the term 'lecture'. This came to the forefront for me when I offered up the idea of TED Talks as one option for learning rather than a teacher's video lecture, and someone said "TED talks are just lectures, so how is that better?" This stumped me as I have never thought of a TED talk as a lecture, which is funny, because now, forced to think about it, I guess they could be construed as lectures, depending on your definition. Which of course has led me to this post!  Obviously, my perception of a lecture is not the same as others. What is MY definition of a lecture? Perhaps it's my many years of being both a student and a teacher, but for me a 'lecture' has rather negative connotations, as I envisio...

I posted an article a while back about my thoughts on the flipped classroom: Math Anxiety and the Flipped Classroom .  In this post, I basically expressed my concern that many teachers are using the flipped model to continue the same traditional way of teaching - lecture and homework, and merely switching where these things happened. If this is how the model is being used, especially in math, it is not going to improve student learning because it's the same old thing. My hope was that those embracing this model were truly doing something different - really using the class time to connect with their students, provide collaborative learning experiences, engaging in real-world applications, projects and extending the learning to make connections - not just reviewing homework. In short, teaching DIFFERENT in the classroom - where the classroom becomes a student-centered learning experience, not just a regurgitation of what they saw/learned in the online 'lecture'. That's...

I have been thinking and planning for my upcoming NCTM presentation on taking the hands-on, physical math manipulatives we use to help students learn and model mathematics to the virtual realm in order to provide  unlimited capabilities to explore and understand. It's something that I think is often thought of as an either or - either teachers use hands-on, physical models or they use virtual models, such as The Geometer's Sketchpad , and my thoughts are we should be using both. It's a way to help students see and understand the power of technology by exposing them to the limitations of the physical and then providing them the opportunity to see the capabilities to go beyond with technology. Some simple examples of what I mean: 1) Geoboards - students begin to explore polygons with geoboards, but are limited by the number of pegs on the geoboard, the number of rubber bands and the physical limitations of both (you can only stretch a rubber band so far before it snaps...

Just a short post today to provide some feedback from my most recent face-to-face with my two blended PD cohorts. Last posting I discussed the focus, listed here: Lesson Five: Provide suggestions and examples of taking the activities/content of the professional development and modifying (adding to, deleting from, etc.) to meet the diverse needs of their students. By helping teachers consider how the activities might need to be altered to differentiate for students, you provide them with power and control over what they are learning, and help them make the PD learning and content their own. Things went pretty well - we had our customary share out at the beginning, where there was some nice conversation and suggestions for helping integrate Sketchpad into lessons. There were some teachers who shared really fun experiences with their students and then some teachers are experiencing real frustration with trying to integrate the technology into their classrooms, from classroom manage...

One of the most frequent questions today at NCTM in Albuquerque was "how do I get the students involved with the software (in this case Sketchpad and TinkerPlots ) using the interactive whiteboard?" Which, if you think about it, almost makes no sense...isn't that the nature of an interactive whiteboard - students are interacting?  But...apparently not. My guess is many teachers continue to use the interactive whiteboard in the manner that they used the projector/screen set up - as a demo tool, with themselves as the driver and students watching. If you want interactivity and student involvement in order to engage students in learning and discovery, then you want them to "drive".  How to do this? Here are a couple suggestions: 1) Have students go up to the whiteboard and be the driver of the software physically, either by following the directives of the teacher or the steps in the activity worksheets or from inquiry and suggestions from other students in the...
