Life on Campus<br />
31 per cent <strong>of</strong> first-year students don’t seek help when<br />
they don’t understand course material, according to the<br />
National Survey <strong>of</strong> Student Engagement<br />
Get it Got it. Good!<br />
A new app lets<br />
pr<strong>of</strong>s track student<br />
comprehension<br />
in real time<br />
Liam Kaufman<br />
Educators now have a better way to know if<br />
they’re getting their point across in the classroom,<br />
thanks to an invention by s<strong>of</strong>tware<br />
developer Liam Kaufman (BSc 2011).<br />
Understoodit is a web-based application that<br />
lets students anonymously express their bafflement<br />
in class. When students load the tool on<br />
their smartphones or laptops during class and<br />
click a red “Confused” button, their input automatically<br />
registers on the pr<strong>of</strong>essor’s computer,<br />
showing what percentage <strong>of</strong> the class is lost.<br />
The teacher can re-explain things in the hope<br />
students will hit the green “Understood” button,<br />
which then conveys to the pr<strong>of</strong>essor what percentage<br />
has grasped the material.<br />
Kaufman tested the s<strong>of</strong>tware in three U <strong>of</strong> T<br />
computer science classes this past February.<br />
Students embraced the tool – perhaps because<br />
it eliminates the fear <strong>of</strong> looking stupid in class<br />
when asking a question, says Kaufman.<br />
But the application was especially well<br />
received by the pr<strong>of</strong>s, who said they appreciated getting instant feedback to help tweak<br />
their delivery. Word-<strong>of</strong>-mouth buzz led to inquiries from 2,800 educators worldwide<br />
within a few months.<br />
Kaufman invited 200 <strong>of</strong> them to try his prototype. With the help <strong>of</strong> another s<strong>of</strong>tware<br />
developer and a user-interface expert, he used insights from the expanded test to<br />
improve the service – including adding a feature that lets teachers poll students.<br />
Kaufman originally wanted to be a neuroscientist – after earning a BSc in psychology<br />
at Western <strong>University</strong>, he enrolled in medical science at U <strong>of</strong> T. But at the same time,<br />
he dabbled in web design and became hooked; after completing his MSc in 2008, he<br />
started a bachelor <strong>of</strong> computer science, which he finished last year.<br />
He launched the upgraded tool in August and is keeping it free for students; he’s<br />
charging teachers a monthly fee <strong>of</strong> $3, but those who register at understoodit.com<br />
before October 3 can use it for free for a year. – Sharon Aschaiek<br />

U <strong>of</strong> T math pr<strong>of</strong>essor emeritus Ed<br />
Barbeau is able to produce this object<br />
using only a pair <strong>of</strong> scissors and one<br />
rectangular piece <strong>of</strong> paper. If you<br />
believe that only one side <strong>of</strong> the sheet<br />
faces up, look again.<br />
This is one <strong>of</strong> many puzzles that Barbeau<br />
used to present to his math class<br />
for non-math students – <strong>of</strong>ten with<br />
great results. “Being good at math<br />
doesn’t necessarily make you good at<br />
puzzles,” says Barbeau. “In fact,<br />
English students scored very highly on<br />
[my puzzles] because they approach<br />
math in a non-standard way.”<br />
Find more mathematical challenges<br />
in Barbeau’s book After Math: Puzzles<br />
and Brainteasers (Wall & Emerson,<br />
1995). – Nadia Van<br />
Cryolophosaurus (“it’s got a bizarre pompadour crest”);<br />
and the Giganotosaurus (“a meat eater that could have<br />
challenged the supremacy <strong>of</strong> T Rex”).<br />
“Yes, they’re a pretty cool bunch <strong>of</strong> dinosaurs,” the 32-yearold<br />
Evans sighs, with satisfaction. Like many, he was turned<br />
on to dinosaurs early, by a childhood visit to the ROM’s galleries.<br />
But unlike most others, he remained fascinated, turning<br />
his passion into a career, pursuing studies at UBC and a<br />
doctorate at U <strong>of</strong> T to deepen his knowledge. He’s been on<br />
digs all over the world, from the high Arctic (“there’s a longer<br />
digging season up there now”) to Mongolia to South Africa.<br />
It was in the last location that the adventurous academic<br />
had what must be the ultimate serendipitous find. The team<br />
was letting <strong>of</strong>f steam after several frustrating days, he says.<br />
“We were leaning with our backs against a cliff wall, tossing<br />
rocks. I happened to look at one before I threw it, and it had<br />
a round outline. It was a dinosaur egg, and there were eight<br />
more in a nest in the cliff.” They’d unearthed a 190-millionyear-old<br />
dinosaur nursery. The find eventually persuaded<br />
scientists that even the earliest dinos were more nurturing<br />
than previously suspected. “These dinosaurs weren’t born<br />
with teeth, so the parents may have fed them, like birds.” He<br />
enthuses about their brain size (in general larger than long<br />
thought) and waxes poetic on their social behaviours, such as<br />
herding. “I mean,” he says, “they dominated the terrestrial<br />
realm for 150 million years. And the last 30 years <strong>of</strong> research<br />
has shown they’re not what we once thought – big dumb<br />
lizards up to their armpits in swamps.” – Alec Scott<br />
