Flip this class

Haven't been blogging because I've been reading, reading and reading, going from blog to link to tweet to blog to you-name-it....no wonder I have felt so scatterbrained and foggy lately - I think I am overstimulated with all this reading, so it's time to cook it all down to something I can focus on: Flipping the class. Inspired by Sal Khan, Brian Bennett, Jeff Utecht, and whoever else I read in the last week.....I'm ready to try it out myself.

I had thought I would start flipping as soon as my kids all had their Khan Academy accounts, and then use his videos for the content, but a few obstacles popped up:

• First, it took so long to get EVERYONE to open an account with me as their coach, in fact, I am still missing a few kids. Partly because of the fact that to create an account, you need to have either a facebook account or a google account, and for most kids facebook is blocked at school, so of course, it's "I'll do it at home miss" but next day oops I forgot. Right. Next year it's all through google accounts.
• Next obstacle: It turns out that nowadays, when you create a google account, you have to supply a cell nbr - I guess to discourage spammers (Ok one of my students told me that, I didn't have a clue why that would happen) and some kids are not comfortable doing that. Sigh. Facebook when you get home then.
• Final obstacle: Me. I should at least be the one making the video, no? Or the powerpoint? I don't teach the same way Sal does, I mean, no two teachers do, but it's more a question of ownership I think. I mean, these are my kids!

So: Doing a psuedo-flip today. Just started a new unit today with Tech Sci Math gr 11 - degrees vs radians. Had a full lesson on ppt, not recorded but pretty complete, with callouts and each step appearing one at a time in the examples...didn't get through it all in class, though, so I told them to watch the rest for homework. That's it. Nothing else for homework. "But", I said, "you will be doing 'homework' in class tomorrow, so be ready to work." Here's the lesson, by the way embedded from googledocs instead of scribd (thanks to Brian Bennett for that idea!):



Formatting seems to get messed up the same with googledocs as it does with scribd...vexing...

Now I have to have a bunch of activities at the ready. A range of them - from simple practice to some Malcolm Swans to enrichment. I also have to adapt this to the online synchronous class, because I can't walk around the class like Brian Bennett can with a camera and see what they're all working on! Unless I make them all write their work on the eboard, which could make the whole thing come crashing down....we'll see what I can come up with.

And one other thing I've been reading about - QR codes. The next big thing, maybe! But later, I'm flipping now, so one flippin' thing at a time!

The Math of Khan (sorry Star Trek fans...)

I had known about this site before I saw the Tedtalks video, but once again, you can know a thing and not know it at the same time. Sal Khan is such an appealing person, and his goal to educate everyone for free is at once humble and great, so now I know about it a lot better!



I didn't realize that there were practice questions, enough to keep anyone busy for a very long time. Nor did I realize the information about who did what questions and how they did etc was so nicely summarized for the teacher, or the "coach." It certainly would be nice to find out that one of my students is practicing trigonometry on the sly, and getting better and more confident to boot.

This week, I will be getting all my students to sign up and register me as their coach. I will show them what's available for them, and see what happens. Then I'm going to try "flipping the class." I'll have them learn something from one of the videos, then we'll do "homework" in class.

I had thought of getting my students to watch my own recording of a lesson, and using that to flip the class, but let's face it, that would have meant even more prep for me, and I have enough of that, thanks, just like all teachers. Sal Khan is doing that part for all of us.

If they ever make a movie about him, there's your title! Now I can start raking it in!

I finally understand the ending to The Wizard of Oz!

Huge tech breakthrough for me yesterday with the Operations on Vectors activity (see embedded doc from Mar 13 post). Totally solved the problem with the different versions of Word that everyone had, AND also addressed my desire to see them doing what they're doing, AND explained the ending to the movie that defines my life!

I "shared" my own version of the vectors document with my students during our class, which in Wimba means that I made the vectors doc that was displayed on my screen to be displayed on all of their screens. They could then see my cursor moving around, grabbing the vector arrows, drawing the resultant with the arrow tool, etc - they could watch me demo how to do what I wanted them to do AS I WAS DOING IT!

But that wasn't the breakthrough. That came when I gave them cursor control. They could then each take turns moving the arrows around, drawing the resultant, changing colours, etc while the rest of us watched! So no more worries about which version of Word they had - we're all looking at mine! AND, more importantly, I, and all of us, can watch them doing what they're doing while they're doing it!

The thing is, I had always, on some level, known that Wimba had that cursor control feature. I just never used it. Why not? I suppose I hadn't connected the dots. As I said, I'm not in my twenties anymore. But I also hadn't created anything like this Word doc that was meant for them to edit, as opposed to just print out, write on, and fax to me. Not only have I now connected the dots, I have first created the dots! Actually, the docs!

So now I am going to see what happens when I use this feature with other software, like TI Smartview, Smart Notebook, Geogebra...things that I have on my computer but they don't, but that I now can use in class with them.

And now for the The Wizard of Oz. Glenda tells Dorothy that she had had the power to go home all along. The Scarecrow demands to know why Glenda didn't tell Dorothy that, and she responds, "Because she wouldn't have believed it!" I never got that until now. Someone DID tell me that I could share and give cursor control, but I didn't see how I could use it until now. My mind was so focussed on other stuff, I couldn't have absorbed the info in order to see how to use it. Maybe that was Dorothy's problem too. She was just distracted!

There's no place like sharing and cursor control! There's no place like sharing and cursor control!

More feedback

Using word with vectors - had one problem - Word 2007 doesn't have a drawing toolbar! Can do same things to the arrows but using something called a ribbon. Two kids couldn't do the activity because none of us knew how to find the drawing tools in Word 2007...vexing!

Classblog - brilliant post yesterday by Abigail, and brilliant questions asked! Maybe I spoke too soon yesterday...

"Creating problems" activity for grade 10 trigonometry class:

Wow, what a success! Continuing creating activities using "Improving Learning in Mathematics", by Malcolm Swan, this time the category called "Creating problems".

First here's what led up to it:

• Did a trig intro yesterday - using sine to find a missing side of a right triangle.
• Homework examples for last night were tailored to require using sin only, like this:

But today first thing, I had them do this:

All I told them was that they could fill in whichever of the two angles they wanted, with however many degrees they wanted, but once that was done, they had to think about where they put the x and the other side length. I think about half of them got the whole opposite - hypotenuse idea right then and there. Not yesterday while I was blathering on about it!


The rest of the activity was pure gold - they worked together so much more organically, because they made up the questions, they wanted their partner to get it right, and they wanted to know that they were right in the first place!

Once they REALLY knew that sine was the opposite over the hypotenuse, the rest of the lesson, which of course was about using cos and tan, went extremely well. They were so much more aware of the significance of the sides involved. In fact Celine asked the million dollar question, "How do we know when to use cos and when to use sin?" and Kaily answered "it depends on your sides. And you use tan when there's no hypotenuse." Weeping I am.

I've taught this many times. I've never had that milion dollar question happening so fast, if at all!

To the Blog Barn!

I love Bulk Barn. When my students visit McGoldblog, I want them to be as excited about it as I am when I go to the Bulk Barn!

Update on McGoldblog:

Feels like it's stalled somehow! We have had a weird couple of weeks, mind you, what with March break and lots of kids absent, not to mention a few days during which internet connections were severely challenged. The result being that there have only been two new posts in the last couple of weeks, and a total of only 3 responses, one of which was mine! That's part of what's making me feel this way.

But I wonder if there's a lack of authentic motivation on the kids' parts. I would so prefer it if they were posting and commenting for some reason other than the fact that I am requiring them to. What if they were driven to, couldn't wait to get their words out there because it was important, or timely, or challenging, or fun?

Maybe I need to get these kids matched up with another class that is blogging, ideally one that is covering more or less the same material. Tweeted about that last week, but I guess I'll have to start calling schools to find one. Charlene commented that she found reading the latest post gave her another point of view besides her teacher's, so imagine what it would be like for them to get that from another teacher's students? Couldn't hurt, might even help.

This and the inherent excitement of going public will surely go a long way to adding motivation, but what else could help?

Blog Barn?!?

Maybe what we blog about needs to be more varied...make it kind of like The Bulk Barn of classblogs! I could sometimes use the blog for something other than the scribing of the lesson, like:

•  a debate on a topic they can weigh in on. I'm following a blog in which one post has resulted in a firestorm of comments and debate. No one is requiring these people to comment. They are simply compelled to by virtue of their own passion and expertise. You couldn't make them NOT comment!
• showing a video like the one I showed on Feb 25 about wealth vs life expectancy. Only problem there is that embeds just don't work on the version of wordpress I'm using. Gotta move McGoldblog somewhere that embeds work easily. Any obstacle for me is like 10 for them.
• showcasing their own work - even if it's just a little voki for fun!
• introducing a WCYDWT problem.

Or maybe it's a question of how I'm organizing the whole thing. I do find that their posts get so deeply buried so quickly that it makes it unlikely that anyone will make use of this rich material beyond the initial reading. If it was somehow done so that they could see more than one post at a time, like the most recent one on one side and a scrollable window of the rest of them on the other. Don't know if that exists. I'll have to check out other peoples' classblogs. I'll have to FIND some other peoples' classblogs first.

To the google barn!

Microsoft Word and vector operations

Putting together a worksheet with vector addition, subtraction, scalar multiplication, for the students to do and while I'm using all the drawing tools in Word, I realized: Why should I get to have all the fun?

Why don't I just give them the vectors, the operations, and have them move arrows, flip them, clone them using the same tools I did to create the worksheet? Then they can even draw the resultants with the arrow tool!

I'll give this as an in-class activity. They will NOT print it up, they'll just open it and move the vectors around to find the answers. Then I'll have them compare answers. Hopefully I'll see something like -  mrs I can't fit the arrows inside the rectangle - really, then why don't you move the arrows around till they fit or - hey my answer isn't in the same place as yours, but it's the same length and direction - is that ok? ...Finally, they'll upload their answers to their dropboxes. No paper.

Operations on vectors

My hope is that performing the operations in this concrete way will make the algebra easier to digest.

Note - it seems that scribd doesn't like microsoft equation objects. They never look right after I've uploaded them. I am terribly vexed.
