A useful Silent Mode

Some guy’s iPhone alarm clock went off at the New York Philharmonic last week. This despite him having the Ringer switch flicked to the “off” position. In this position the switch shows a little orange line.

This weekend, the blogosphere has been a-buzz with contrasting opinions on the implementation of “silent” on the iPhone. Read Hivelogic to get up to speed if necessary.

Short version: iPhone’s silent switch is actually not a “Silent Mode” in the Nokia or Blackberry sense of the word. It is a “Ringer Off” switch. That means that certain user-triggered activities, will still produce noise. Apple notes this in the iPhone User Manual:

Important: Clock alarms, audio apps such as Music, and many games still play sounds through the built-in speaker when iPhone is in silent mode.

Nevertheless, some bloggers are calling for the switch to be changed to a Mute-All switch. This would do away with one of my favourite iPhone design decisions. In fact, I have overslept at least one important business meeting because I’d left my Blackberry on silent the night before.

I need a phone that:

  • Stops making noise (phone calls, emails, messages) when I go to bed,
  • and then starts making a lot of noise when its time for me to wake up (alarm clock).

It’s pretty simple.

Hand crank OLPC

The Verge on the OLPC XO 3.0 tablet at CES:

That power jack will accept the tablet’s regular AC adapter, but also other sorts of power sources, including a hand crank.

Love the idea of a tablet hand crank.

The Culling

Prof. Jonathan Jansen writes:

There is a nasty micropolitics of schooling at play here. It is common knowledge that schools, under tremendous political pressure to improve their pass rates, do two things.

They hold pupils back in earlier grades, especially Grade 11; and they downgrade pupils into easier subjects, such as mathematical literacy over pure mathematics.

In other words, the greater the chances of pupils in Grade 12 passing, the better the school looks, the better the province looks, the better the country’s averages look.

The department acknowledges what it calls “culling”.

Pause for a moment and just think about that.

This is (partly) how our education system lost 539 102 learners between enrolling in Grade One in 2000 and now.

The $100 OLPC tablet

Gizmodo and The Verge are reporting that the OLPC XO 3.0 tablet will be shown off at CES next week. What’s more, it is expected to go into production very shortly and apparently reach the market at a cost of $100. This is impressive considering the specs:

  • 8-inch, 1024×768, PixelQi display
  • Marvell Armada PXA618 processor
  • 512Mb RAM
  • Android or Linux Sugar Operating System
  • Rugged case and soft-rubber cover

OLPC has noted that the $100 model won’t include the expensive PixelQi display but instead has a normal LCD.

KidsRuby is Ruby programming, for kids

And it looks great. A lot like Hackety Hack.

If you have a kid who’s even slightly interested in computer programming – let them play with this.

Sinking deeper

Professor Jonathan Jansen, Vice Chancellor of UFS writes:

With the society that sets the bar for performance so low, I have serious problems. Slowly, slowly we are digging our collective graves as we fall into a sinkhole of mediocrity from which we are unlikely to emerge.

Behind a massive wave of populism, and in the misguided name of regstelling (setting right the past), we open access to resources and universities to young people without the hard work necessary to achieve those gifts and to succeed once there.

Straight to the point, as always.

Department of Basic Education distributes open-licensed textbooks

Arthur Attwell writes:

The Department of Basic Education has printed open-licensed science and maths textbooks for every grade 10 learner in the country, and will follow up with grades 11 and 12 soon. I’ve heard estimates that this is around two million textbooks in each grade.

This is a big deal. And I suspect it’s not the last disruption the textbook industry will see this year.

Can Higher Learning be made habit forming?

Anthony Koser for Forbes:

Just making the coursework available for free, of course, doesn’t make people use it, no matter how good it is.

I can’t tell you how many times I’ve started the Stanford iOS course.

Matric 2011 in review

South African students will breathe a sigh of relief tomorrow morning as the 2011 Matric results are released. This evening we got the summary data, and in general the numbers are good. 70,2% of state-school candidates passed (up 2% from 2010) and 24,3% gaining university entrance (up just under 1%).

Students attending independent schools (which sit the equivalent IEB tests) performed exceptionally well. Of the 8 285 candidates, 98,4% passed and 85,5% obtained university entrance.

To make sense of these results I gathered government data for the last four years:

Matric pass rate, per year (Overall pass rate and university entrance obtained, respectively):

  • 2008: 62,5% and 20,2%
  • 2009: 60,7% and 19,6%
  • 2010: 67,8% and 23,5%
  • 2011: 70,2% and 24,3%

On the surface these statistics paint a picture of rapidly improving standards. However, given the pressure on government to both prove the value of the “new curriculum” and improve performance – especially in rural South Africa – one must ask the poignant questions.

Is the difficulty of final examinations being gradually reduced to improve performance? Are marks being adjusted upwards to compensate? And, critically, are school-leavers educated at a level to indeed enter university or adequately equipped find a job after school?

Update: NGO Equal Education highlights a concerning reduction in the number of candidates: 496 090, down 41 453 from 537 543 in 2010. They also note that 923 463 learners started Grade One in 2000 indicating an approximate 46,3% drop-out rate over twelve years of schooling.
