Greenhaus Education and Other "Effects"

Today is October 21, 2015 and Marty McFly is set to arrive this evening, so of course, a post about the technology that actually exists today compared to what the movie predicted is in order! Someone else has done all the work for me and gone through 22 things that the movie got both right and wrong - I will let you check that out on your own. Here's a movie trailer clip that shows the some of the "things" of the future:  What I find amazing to consider is that the writers/creators of the movie were making predictions about a future 25 years down the road in a time, 1989, where none of this technology existed.   Heck - the World Wide Web was just being born in 1989. And yet now, 25 years later, some of their predictions are in fact a reality. We have 3D TVs & movies, we have Google Glasses, digital cameras, tablets, talking computers who can do things for us (Siri), and while we don't have flying cars, we do have electric cars. It's like Star Trek t...

I have been doing some independent research on technology use in classrooms.  With all the news about 1:1 classrooms and students using technology apps to learn, I was curious about what is actually happening.  Some of my findings have made me really question whether some of our approaches - i.e. 1:1, computers vs. tablets, are really supporting the way students are learning with technology. I found this interesting report from Project Tomorrow called "From Chalkboards to Tablets: The Emergence of the K-12 Digital Learner"    with some fascinating statistics regarding the technology students are using to help them learn.  You should download the full report (available as a PDF), but I will share a few of the findings here. One thing that stood out for me is the prevalence of smartphone use by students, especially as they get into the upper grades.  Table 1 below shows the use of both personal and school provided devices.  Very apparent that 1:1 and...

I hadn't really thought about QR code use in educational settings until my recent exposure and personal experience with a new app. EDU + , released by Casio to support their Classwiz scientific calculator . It got me interested in how QR codes are being utilized in classroom settings. In my research I have found some interesting suggestions for using QR codes in education. Steven.Anderson has some great postings and links about QR coding ,which led me to several articles and resources. One in particular, Tom Barrett's slide show on " 40 Interesting Ways to use QR Codes in the Classroom " gave me insight into the possibilities of QR codes for teaching and learning. I particularly liked idea #7 of adding QR codes to word documents for students to check their answers. He has 40, so it's worth a look! Basically, QR codes are information - up to 4000 characters. QR codes can be used to link students to more information (reviews, pictures, graphs). Embedding QR c...

I just read yet another article about the push to lengthen the school day in order to improve student achievement entitled Learning Takes Time: Growing Movement Seeks to Expand the Length of the School Day by Celia Baker. The last paragraph of the article I think highlights the advantage of this idea: "More time and money won't help if they are not well-spent, Gabrieli cautioned. The National Center on Time & Learning report suggests that additional time be used for more engaged interaction in academic classes; broader curricula; enrichment activities that boost school engagement; and more time for teacher collaboration and professional development".  As with anything in education (think technology), if it's done right and planned out and designed to address specific needs, it will have an impact.  If it's done for the sake of being done with no real plan or purpose, it is NOT going to be effective. Adding hours to the school day so that students can ...

It's that time of year when I really miss teaching - the start of the new school year where everything is fresh, exciting and new. There is so much hope for what lies ahead.  I remember going in with all these great ideas and new things I was going to try and being filled with the thought that I was really going to be better this year and my students were going to have amazing experiences that would just spark their learning. I miss that. Some years it really did pan out the way I hoped. Most years, there were ups and downs. But - every year was a new challenge and every year I tried to do things differently.  Granted, I was usually teaching the same subjects, but that didn't mean I had to do the same thing, did it? I certainly didn't believe so. Sure, I may have used some of the same projects or activities, but I had different students, I had learned some new things over the summer, and I didn't want to be bored repeating what I had done before. The same old thin...

The question - does social media impact personal life? The answer - yes.  Is that a good thing or a bad thing? The answer - it depends. I have been on vacation the past week or so and am currently on personal leave to finish writing my dissertation proposal (which, as you can see, I am procrastinating!) During my vacation, I swore I would take a break from blogging, Twitter, email, and all things electronic. I lied. I admit - I did honestly make the attempt and in fact, did not turn on my computer one time.  However, the iPad is a constant companion, especially since the books I am reading (currently, the Game of Thrones series) are on there, so I had the iPad with me a lot - even on the beach.  It was very easy to check if I had emails, to check out my Facebook or to send a Twitter or two.  Long story short, I failed miserably at the disconnecting aspect. View from chair and under canopy! Which brings me back to the question of does social media impact p...

As I wrote in my post last week, I was heading to ISTE 2012 in San Diego. I wrote about several things the conference had to offer that I wanted to explore, so I thought this would be a good time to provide some feedback since the conference is now over.  First, I was so impressed with the technology, which of course one would expect at a technology conference. But, the fact that throughout the entire conference free wifi was available was really a bonus and something that other conferences really need to consider. It allows for participants to stay connected. All the tweets and blogs that occurred throughout the day provided additional support and exposure of the conference,which I think might outweigh cost.  Second, I really felt the structure of the conference fostered collaboration and gave everyone time to see exhibits and learn without feeling torn. I know at the math conferences there are so many presentations scheduled at every time, with no breaks, so as a pa...

I am going to the ISTE 2012 Conference in San Diego this coming weekend/week. That in itself is pretty  exciting.  It's my first time at ISTE, not for lack of wanting, more for lack of timing and cost.  I am very excited knowing I am going to be immersed in technology, meeting other ed-tech enthusiasts, and just learning more about what's out there that can help me personally and professionally.  Another reason I am excited is that I will experience a conference that has some very different options from the math conferences I usually attend. I am not knocking math conferences. Rather, what I am pointing out are the many ways in which the ISTE conference differs in what it provides in the way of collaboration, networking and technology that is unfortunately, not often a part of math conferences.  This may be true of other content specific conferences, but since I am most familiar with math conferences, that is my point of reference. I am sure a lot of it has...

I have been writing a piece about dynamic geometry® software, and have had a really difficult time conveying the power of dynamic mathematics environments in the static environment of the written word. Let me clarify what I mean by dynamic geometry software - I do NOT mean software that is just for geometry.  Dynamic geometry means the ability to take all sorts of mathematics visualizations (shapes, graphs, plots, functions) and drag and manipulate them to create infinite examples. These dynamic movements follow mathematical behaviors and allows for exploration, discovery of relationships and properties and allow students to interact directly with the mathematics because the mathematics is visual and tangible. Dynamic geometry software is specifically mentioned in the Common Core Standards of Mathematical Practice because of it's ability to be a tool that promotes reasoning, questioning, making conjectures, persevering, modeling, and communicating. Naturally, I have a strong bia...

I am preparing for my final face-to-face meeting with the two cohorts of middle and high school math teachers I have been working with the past 6 months.  We will still have one more online component, which ends in June. I am a little sad about the fact that our journey is coming to an end, as it has been one of my most rewarding professional development experiences, in large part because I was able to really get to know these teachers both personally and professionally and actually see the progression of change and confidence as they learned and integrated Sketchpad into their mathematics instruction. A quick recap of the five previous face-to-face lessons, or focus you might say: Lesson One: Begin professional development experiences assessing background skills of participants. Lesson Two:  Work on building a sense of community and support among participants, where they feel comfortable sharing their struggles, their experiences, their ideas and expertise. ...

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...
