Algebra II – The Key to Success?

Filed under: education,math — admin @ 12:13 am

The report: The Final Report of the National Mathematics Advisory Panel highlights this comment:

“Students who complete Algebra II are more than twice as likely to graduate from college compared to students with less mathematical preparation.”

Oh my.

What other subject gives this statistic?

What is about Algebra II that gives this result?

I also ask.

How many of us pay “double taxes” for mathematics education for our children?
Taxed once for schools and again for tutoring. I do.

Again from this report:

Moreover, there are large, persistent disparities in mathematics achievement related to race and income—disparities that are not only devastating for individuals and families but also project poorly for the nation’s future, given the youthfulness and high growth rates of the largest minority populations.

And this is true where I live too – not just in the US. So I bet it is true in many, many places.

Now – what are the answers to these questions and what do we do to change the situation?

Vindicated – How sweet the taste of these grapes :)

Filed under: education,ICT,math — admin @ 3:53 am

In today’s New York Times – I saw a report: Report Urges Changes in Teaching Math

The report: The Final Report of the National Mathematics Advisory Panel

And we had just finished our paper the day before that made so many of the same points (also has some concrete ideas for solutions): ICT in Math Education – Small Interactivities & Specific Goals

How sweet the taste – after so many sour grapes this month!

————

Someone asked me what I meant about lighting the fire and filling the bucket in mathematics education …

In the US, math education has swung completely towards a “lighting the fire mentality” . For example, one doesn’t need to know the multiplication tables by heart. (I really didn’t think anybody could believe this until – no kidding – a university professor of ICT actually said this outloud at a conference: “It is enough to know that 6×7 is somewhere between 30-something and …”. By this time I was laughing so hard I didn’t hear the rest of the sentence.)

On the other hand, here where I live in Europe, the emphasis is on “filling the bucket”. For example, a child must memorize a formula for the volume of a cut-off pyramid. That is, not just memorize the formula for the volume of a pyramid, but also a formula that (a) you will never, ever need and (b) makes our students dummies. Why? Because the top of a pyramid is just another pyramid. So just use the one formula twice and subtract. Let’s just say to these kids – “no thinking permitted”.

The result is the same – neither child can “make the coffee”, i.e. do math at any level of competence AND both hate math.

One interesting feature is - both schools reward lots of “partial credit” on tests. How many bosses do you know reward “partially done jobs”?

And – if you think this problem is only in math:

My child here in Europe – had to know that in the population census in our country in 1935 there were 532,381 people – that is, an exact number for a definitively inexact figure.

On the other hand, in my US education, I am still unsure of even the relative positions in time of Shakespeare, the protestant revolution, the renaissance, Napoleon, the middle ages, Columbus, Walt Whitman, the US Civil War, etc.

It’s about making coffee – Light the fire & Fill the bucket

Filed under: education,ICT,math — admin @ 1:09 am

I was just looking at the byline on an email I received from a “Professor of Education”.

It said – It’s about lighting a fire, not filling a bucket.

No it’s not.

“It” isn’t about either of these things separately.

“It” is about being able to make the coffee.

Sour Grapes or Sour Grants: Judging the Judges

Filed under: education,ICT,SL — admin @ 1:50 pm

There was a contest. (It has “winners” – so that makes it a contest.) It was called DML – Digital Media and Learning Competition or HASTAC initiative, and it was supported by MacArthur Foundation (which does many cool things – I checked!) It was supposedly for innovators who have new ideas to improve the education of our young people. Money for the little people with big ideas.

But that wasn’t so. What they really wanted was to brag that they had over 1000 applications for <20 grants and then change the rules and give the grants to their cronies in higher education. Not grants for innovators – just typical university grants. Say it up front. Don’t lie.

Let’s look at what they said they wanted.

As early research begins to illuminate changes occurring in young people who are “growing up digital,” the time is ripe to translate this research into concrete designs for new kinds of learning environments. …

Innovation Awards support pioneers who are exploring new digital models of learning that build upon and enhance the informal, networked, and collaborative styles today, especially but not only among youth. These projects demonstrate new modes of learning in many environments.


Now look below at the judges qualifications*. We don’t need names – this information alone would have been enough to tell us the story.

Look carefully. There are no teachers* - incredible isn’t it. You want experts? Where are the “teachers of the year”? The experts in the field – the ones actually working with kids and teens. NOT ONE! Look again. There is no one from math or economics or physical sciences. Jeez-louis, how is this possible? Why don’t we just stop teaching this stuff in our schools if it isn’t important.

Look again. There are 7 judges who develop and design computer games. That is, 7 out of 35. Unlike so many of our young people, I am able to do math so I will translate: 20% of the judges are gamers. Look again. There are 23 judges who are either university professors or directly related to higher education. Again I will translate (okay, I did it with a calculator): 65% of the judges are in higher education. The other 15% – OMG as we say in SL.

Now it is reasonably easy to deduce what they are after – others need not apply. NP. Just tell the truth.

And then, the unmitigated gall to blog jovially about the 980 who didn’t get a grant applying again – like our time, our dreams and our real innovations for educating youth are games. Absolutely disgusting.

Sloodle Moot Itself

Filed under: moodle,SL,sloodle — Tags: , , , — admin @ 2:31 am

This will have to be a quicky – Sloodle Moot deserves more, but I haven’t time.

Talk about bad timing – installing Sloodle requires Moodle 1.6 or 1.8 . My server is just now in the process of transitioning to a different platform (I love all this geekese!), which means I can finally upgrade from Moodle 1.5. Unfortunately not in time for the Moot. So consider that I attended the Moot only knowing a bit about Second Life and an old Moodle and no real experience in Sloodle.

Here are my thoughts on the moot and the events and the presentations I attended.

1. Giannina Rossini must be comatose today as well as her fellow Sloodle Moot Supremos. I have never – ever – seen such extraordinary conference organization and in the still rather non-forgiving environment such as SL. And Gia was at every presentation (4+) and every event (2+) I attended.

2. The Sloodle Moot Auditorium

• I liked that it was walled off until the Moot opened. I am sure that this was done for the conjurers benefit, but it added to the fun of the opening.

• A small minus here – I tried practicing the teleport coordinates in the days before the Moot because I knew I would be short of time on a Saturday . It was a bit confusing to try to teleport to places I couldn’t get to.

• I rarely socialize in SL (not very good at this yet), but it was lovely to watch all the partying so thanks for all the fun lighting – the robot was cool!

3. Skylar Peck, New Nexus

• I wasn’t terribly interested in this, but it was the first event on when I got up in the morning (CET – overslept for the Jeremy Kabumpo presentation) and I liked that the voice worked.

4. Edmund Earp, Hacking Moodle

• This was absolutely the coolest presentation I attended. I was so engrossed and engaged that I totally forgot to take pictures. This presentation made the Moot for me.

• It showed a real application of sloodle, i.e. moodle and SL together – the quiz chair.

• We got to make our own and I learned not just how to do that, but also about quizzes in moodle and technical prim making stuff in SL like how to drag scripts from one prim to another.

• BTW – Don’t rotate and object that you plan for people to sit on. I sat on my rotated cone with my head in the sand :)

5. Pedro McMillan, Moodle-SL Interactions

• This was a very fine presentation – I loved the pipelines and how the lit up when you were presenting; please tell us how to do this!

• I don’t know alot of technical stuff, so I didn’t really understand exactly how the flow works, but it was so well presented that I got a good idea of what flows in what order between SL and Moodle – so well worth my attention.

• I must remember to write and ask which flows are for course setup, which for teacher and which for student?

6. Esme Qunhua, Discussion

• I tried and tried to find this in some astro place – the teleport coordinates just wouldn’t work. Then I saw the location had been changed, but by the time I got there, it must have been over. (I was dumb and did not download the updated schedule – basically because I had been given the (old) schedule on a SL notecard and put it into Word which was easy for me to look at and on Sloodle it was only available in xls or pdf – picky me).

7. Jeremy Braver, Educational Games

• This was great fun and the presenter is a whiz at engaging the audience but (a) I didn’t really see how it fit into the Sloodle environment and (b) was dissappointed when I found out the game will be for sale. (I live in a country where even a $10 game is alot of money.)

8. Buddy Sproket, Scripting

• Firstly, this was a very interesting presentation. I liked all the applications; I must admit I didn’t see how they function in Sloodle, but it was information I wanted, it was well presented so that I could follow most of it and I love Buddy’s hair.

• Secondly, I must apologize to Buddy and all of those present – I didn’t realize that my scripts from making prims in the back part of the sandbox would come into the chat window. I thought it would be like Edmund’s quiz chair demo and I am VERY hands-on so I wanted to try as I watched. So please forgive me.

• I have to admit that as we went from scripts in SL to php I got kind of lost. I couldn’t follow how the script in the prim and the php on a server were connected. It is entirely probable that I was not the intended audience profile :) . But I learned alot and saw possibilities so I am very glad I attended!

Oh my gosh – I did not realize that I had actually gone to so many presentations!

Still, I wish I could have gotten to more events.

I had a wonderful time, learned alot and my thanks to all the SUPREMOS and presenters!

Sloodle – Second Life and Moodle

Filed under: moodle,SL,sloodle — admin @ 7:32 am

Yesterday I attended a sloodle mini-conference. What’s that you say?

Cool beans my friends - and hence I will go to Sloodle Moot starting January 18!

I admit, I wasn’t expecting much. But I enjoy Second Life and I use Moodle in my teaching so off to the mini-conference I went.

Here is what happened …

  • I was at home in my jammies (it went from 12 – 1:30AM CET) in a village in FYR Macedonia, sipping tea (and then the caffeine was duly processed and I was also able to take – hmmm – what is the current euphemism – ah yes – a comfort break).
  • I was present in Second Life in all my 3D glory as Janita Collins (my SL avatar) in the ISTE island auditorium and
    • I was chatting with my co-participants as we arrived and being introduced to new persons, and then
    • I was sitting in a comfy chair, listening to the speakers (yes audio and at a level I could control!), watching a powerpoint presentation, and then
    • I was raising my hand, asking questions and having them answered in real time and then
    • I was picking up virtual handouts, and then
    • I was applauding and waving goodbye at the end.

A actual (better than RL-real life) conference! I was amazed. This is my third SL presentation and SL is really coming along. The audio worked, the powerpoint pages focused in real time, the ISTE auditorium is really cool. The handout boxes worked. Just in SL, I was impressed.

But wait – there’s more …

  • At the same time we were “at” the SL conference, we were Moodling. That is, we had our browsers open and were attending the Moodle course for this mini-conference. So I could
    • study the conference materials
    • look up words that I didn’t know in a online glossary
    • review a powerpoint slide that had gone off the SL screen
    • taking part in a real-time blog with the same participants
    • and all this without anybody seeing that I wasn’t actually riveted to the speaker (oh sorry, I am always getting in trouble for this at a RL conference!)

I didn’t understand it all – but what I saw was actual potential for actual use. My kind of technology in education.

Now, I am truly looking forward to the Sloodle Moot!

My thanks for great presentation to: Gia and Buddy and KJ and see you soon!

My thanks to Esme Qunhua and Entropy Hax for the wonderful SL tours from SLolar -> Gia ->Sloodle -> SloodleMoot!

Facts+Skills+Thinking: Applets and the Vitruvian Learner

Filed under: applets,education,ICT,math — Tags: , , , , — admin @ 12:44 am

We want our learners to know facts, to have skills and to be able to think – a perfectly proportioned Vitruvian Learner.

I am preparing a new course on ICT* in Education. Most of the literature on this is depressing – no kidding. Everyone is still so enthusiastic about the future of ICT in education, but most admit that current ICT integration has brought no significant breakthroughs in student learning. ARGH!

At the same time, I was just designing a set of math applets** for measuring angles with a protractor (link). This turns out to be an exercise for which there are many, many, many such programs available. ARGH!

Of course, I think my applets are different – they will bring the breakthroughs. But why should they? For the moment, let’s assume that magically my applets are loved and are being used in every classroom in the land …

What about these applets might bring a breakthrough in student learning?

To be effective:

The applet must be a perfect proportion of facts, skills and logical thinking processes both required to use and acquired from use and

• this required perfect proportion must apply to a large number of learners.

• this acquired perfect proportion must apply to a large number of curriculum.

One easy conclusion – the smaller and more focused the application – the better chance it has of meeting these requirements. Hence, applets and not mega applications probably are more practical.

Even more essential is communication with teachers because a teacher will not use ICT unless it can be used within the curriculum, i.e. within the framework of “this is what we know so far and this is our goal in this lesson”.

So – just from the point of view of bringing a breakthrough in learning – and before designing an applet, we must ask.

• What are the facts one needs to know to use and what facts will be learned?

• What are the skills one needs to know to use and what skills will be learned?

• What types of logical thinking process are required? What thinking processes will be learned?

Then: Do these answers fit a broad spectrum of learners and curriculum?

Yes? On to the next checklist …


* ICT: Information and Communication Technology, sometimes just IT.

** applet: A little application frequently run from a browser window with limited features that requires limited memory resources.

More than “What kinda map ya want?”

Filed under: education,ICT — admin @ 1:49 am

We all know the story about the kid who couldn’t find Iraq on any map, but when asked to find Iraq on the Internet, the kid said “What kinda map ya want?”. Oh cool – our kids are so smart. But is this the end of the story?

  • Is it enough for our kids to be able to say “What kinda map ya want?” ?

I think not.

The right idea: As teachers, parents and citizens we complain our kids can’t find Iraq on the map. Now, we are told that this is the wrong quiz question for this generation and – in fact – the wrong quiz question for any generation. I can find countries on a map; I can drag out my 35 year-old NG atlas and probably give you alot of information from it without even looking. But I will have to be very, very lucky if I can answer a real question with that information.

  • Eureka! What we really need is all kinds of maps at our finger-tips so that we can find the right map that answers the question.

The (not-quite-whole) story: Just yesterday my son needed to use the formula for the chemical process of a car battery. He could not understand the explanation in his textbook. It took us 5 minutes to find it online; we found several references so that he was able to confirm the formula (different from the incorrect/incomplete one in his textbook). Then he looked through the different explanations, printed out the one he could best understand, reread it, annotated it and started successfully solving the problems.

  • Eureka! What we really need is a new education. Our kids will be able to quickly find all kinds of maps.

The (not-quite-right) conclusion:

Our kids can find any map – hence they are learning the right stuff.

Bad deduction – just the bad kind of mathematics I hate. No thinking involved!

The real story: Notice the “it took us 5 minutes to find it online”. There is a whole story here (and many wasted hours and frustration) before we got to this point and it was me – the old lady teacher, with no knowledge at all about chemistry – that was able to get the right stuff and show him how to use it.

Why? Because whatever and however I got it and whether it is library book or internet based -

  • My education taught me the thinking-steps to use to get me with confidence from question to answer.

Neither question: “Where on the map?” and “What kinda map ya want?” is the right kind of education.

  • What we really want is to hear our kids say: “Yes! Here’s the map I need!”

These blogs – my SL2RL journey – is to explore specific, step-by-step, ready-to-use, free stuff using technology that can help get our children get to this “Yes!”.
