Grockit https://grockit.com/ 1. Grockit does a fantastic job of
encouraging interaction, and after
adapting to the system I really
enjoyed interacting with the few
kids I joined in Multi-Player
games. Of course, your mileage
may vary, and I’m sure there are
some trolls, but my interactions
were nothing but positive. Multi-
Player math practice was by far my
favourite thing about Grockit, and
while “playing” I actually lost
track of time and stayed up far
later than I had intended to.
2. The adaptive learning system
seemed to assess my math ability
level quickly and started feeding
me only high difficulty questions
when I was in a “Solo” game. That
kept me engaged and appropriately
challenged.
3. It was easy to view a summary of
my performance, broken down
nicely into different skill categories,
each of which offered additional
practice problems. This is an
important part of the SAT prep
process,and one of the hardest
things for students to do by
themselves.
1. After practicing for about an
hour, I started to see algebra
questions that looked very
familiar. They had a few
cosmetic changes,but were
otherwise identical to questions I
had already answered. That made
me wonder how many total
questions there were and how
often I’d see repeats if I did it for
a month. Repetition can be a
good thing, but I’d prefer a little
more variety.
2. It’s hard to answer math
questions on a computer screen.
This is also, I’m aware,a valid
complaint about my own site.
Bottom line: you’re going to
want to have scratch paper handy
if you want to get anything out of
your time on Grockit’s, my, or
any online math practice.

Wikispaces http://www.wikispaces.com/ 1. Games can support
collaboration, problem-solving
and communication in learning
communities.
2. Students are often engaged
when learning through games.
Games are designed to have
the appropriate balance
between success and
frustration in order to keep
players motivated to persevere
(flow).
3. Digital games meet the
needs of "digital natives",
learners who have grown up
with technology (Prensky,
2001).
4. Games often provide instant
feedback and reward as
students master activities or
levels, and give students
ownership and control of their
own progress.
5. Develops a highly engaged
environment where students
can redefine, evaluate and
enhance their skills by playing
games that challenge them.
1. Most current games
involve sitting at a computer or
console rather than being
active. A study by He, Piche,
Beynon and Harris
(2010) reported that Canadian
children spend an average of
3.3 hours per day in screen-
related activities, which may
contribute to the growing
problem of childhood obesity.

outcomes of game play
assessed and measured for

Pinterest https://www.pinterest.com/ 1. Strong social media tool
for companies/brands.
2. Easy and simple to
use, especially with the “pin
it” button that allows you to
pin an item on any website
without having toA strength
of Pinterest its simple &
visual grid layout.
3. It has one focused
function.
4. You can immerse
yourself into
an enormous visual
community.
5. It’s personal and
interactive.
6. There is equality among
all users (whether it is a
brand or a person) in that
both have access to the same
features.
7. A pin can take you back
to the original website if you
want to learn more about the
item that was pinned.
1. Users feela lack of
personal touch in their boards
since pins are usually already
been pinned by others.
2. Links of pins are follow
able by google, creating
spam.
3. Debate whether photos
taken from websites are
compliant legal rights of the
original owner of that photo
(then again, each pin links
back to the original website,
giving the original poster of
the photo credibility)

Schoology https://www.schoology.com/home.php 1. Has a more
‘Facebook’ feel (you can
‘like’ people’s posts and
comments) which makes
it instantly more popular
with teens. It has been
popular even with my
very selective students.
2. It is very easy for
students to upload their
work from their iPad.
None of my students’
have ever had a problem
uploading their work,
and it is a breeze to
return the work with
comments.
3. You can individually
assign work/assignments
to help differentiate your
class. This is easier than
giving every group an
individual code to access
it.
4. You can create
‘discussions’ that are
separate to the ‘updates’
section. While updates
are good, they get lost in
the stream of
information.
1. It is still difficult to
upload any student work
that is video or image
based.
2. It connects your class
as a ‘course’ not a ‘class’.
This makes it easier for
high school teachers,but
for my single class,
students became confused
as to where they needed to
go for their assignments,
discussion boards etc.
