a
i
i
oh
we
talk about
uh
a
a
was
or
i
oh
or
a
i
just
we
so
oh
or
i
a
i
oh
vol
oh
a for a lot
what's on
i
well
we're
uh
oh
so store
you
a
i
i
i
a
you
a everybody's great to be here can you hear me okay in the back
so uh
it's great to be here to talk a little bit about what uh
these signal processing education technical committee
is been thinking about as far as a emerging trends
in signal processing education as when mention
a and the portal caviar i
about uh today's talk is
but a lot of things were
at least today are
our opinions
and all very important in the break
in between the various little some sections of the talk that
you jump in with what you feel might be
uh other trends more interesting trends or projects going on within these trends that are uh
i interesting are also interested in hearing about
some trends
uh some some trends and some sub
train
so the the the key issues that people are really starting to
a a move from actually O uh move from awareness to actual action about over the last years are are
for a listed up your the first is
the need to move towards a more learn or set or sent
uh a learning environment
a a meeting uh a loud that the curriculum do adaptable to learners level and also they're their contact
and also really try to transfer the responsibility of learning
from the instructor to the
do right to the lower that cell
uh
a a big problem with doing this is there some road blocks
right the row blocks related to
the fact that the education experience for too many kids today
is a a very pass
right we sit we listen what we doing right now right we sit we listen we make notes
uh we go home and and work on hold
a a it it's a very inefficient way to teach a very inefficient way to learn
uh one of the problem there's when we try to do things differently we end up with a row block
um
a a a a a a a a
educational materials speed a lecture materials text other materials are very flexible
and have been very difficult to bring the more learner centric or more ah a a yeah yeah
a a teaching a philosophy
yeah
and finally late when a people are starting to realise that that they need to be thinking about how to
bring a lot of the kind of experience that we have to laboratories
a hands on experiences into in both the classroom and into that the home
a a a of of that the student
and then people are also realising that we might build the whole mechanism to do that attack and problem but
are we get a
put the stuff out there
are we gonna maintain a and how are we can ensure that
quality remains high
right and not D greats oh
oh i gonna talk about about four
a us that trends that the that people that been uh moving into with over the last couple years
and after i finish each one of these little trends
when is gonna hop but right
in go at
people if they have any a
con
oh the first
has to do with
the idea of moving away from the standard
paradigm of text but
to more open source or free text books everybody knows what we keep P D a
how can we take ideas like this to
uh a other kinds of learning you're
and uh a key enablers of this or first that technology has come along in about the last two decades
case
that of enabled us to rethink think
the text book as instead of as Z six hundred page
pile of paper right that's been glued together
to think about it instead as a collection of a
maybe smaller learning modules jewels are learning object
that can be combined together at all kinds of different way
oh that instead of having
the six hundred page book of which only two hundred and fifty pages is used it any anyone of our
institutions
is the different two hundred fifty pages
by doing things and this like go block a a set up we can rapidly customising reconfigure books so there's
just the perfect book for everyone of our differ
clay
this would not be possible if that wasn't safe and easy to pull together these like a blocks and the
other thing is really move forward the last decade or so are
open content licenses things like the creative commons license
the make it really easy and also very safe
to share
a a a very much like the G P L sit
really enables the explosion of letting
open
or software
quick sure that creative commons some people low
if you don't you should write that down creative commons dot org
and definitely check it out and and joined at would last i checked
there are about two billion
creative commons license works up on the inner
"'kay" tremendous to men
a one example is actually that
the project we start or right twelve years ago call connections which is that
exactly that's a lego wise text but
a shane off the in publishing environment
we currently have about a a of hundred of these open text what's
you know a whole bunch of different areas from little kids readers for three four year olds
there we in india
all the way a to a post graduate a course
a very yeah uh important thing is that these materials are from folks
probe uh world wide
yeah both forty different languages
and we're supporting right now roughly two to three depending on the but
million unique users promote uh coming to the
so with
actually one and a I T open courseware connections are the two largest and
most used uh open education
as to give an example of what is like
in connections
all the materials are viewable as web pages that really the X M L web pages
right here but there also view the uh i i on your smart phone or your i can right carry
them around or get them through I tunes you for example
and everything is also available through a
a C print on demand engine that lets you pump out of very professional quality for text books that you
can see the price
are you hundreds of dollars
in some cases cheaper than
uh a can be
it's and that's real that's
basic idea of like connections there's
uh a just because it was start by signal processing people there's is a lot of client it already and
there
in signal processing a a a a uh a actually several thousand modules already
and that will will come back around of this at the very and what of the purpose
this meeting is
to get more more than of all the contributing
but you
when you jump up or
my
mean
a few words with keep year
i mean that
oh
a
oh
a
i
oh
people here
use would keep you your regularly
okay
for signal processing like the your work
not for you know
other other stuff
okay
how many if you have actually contributed or and
a we keep P and
"'kay"
so i think that's one of the things that we need to do as a society i think it's
does that
membership and the committees need
start generating higher quality
we keep P entries for a lot of signal pro
oh
and
right
so it's a soul connections in particular
we have a
like we keep you we have a very high google karma
so anything thing that's in connections and that usually in the top three
so yes
a that's just because there's someone was christ linking the goes on a but we also do talk to google
regularly and i'm actually going to use day
a a to talk more with a
yeah and in map
yeah a quest
yeah one of the things is really really nice about
open access but you're and the a is you can get
absolutely unbelievable amounts of use of your stuff so
connection started twelve years ago what i was gonna write a book can instead of writing a book i decided
to
P this
right but i did put might but eventually in connections
and it's been used the above five million time
right which is
sure unbelievable the think about when you compare with what i
use you would got from
okay so that open open education
so of video tutorial
was about the con academy
sure hands
"'kay" write it down
con academy dot war
there's this crazy guy
sound so
uh i guess i will talk about of for just a minute
yeah of a former or ah a hedge fund manager
who just started to his cousin
actually it is
nice nice and F you one day
a a remote
and he started using software to tutor them
and they told their friends and they told their friends and they told their friends
he has turned in to basically on once you're of developing a little ten minute video tutorials on
basically he wants to do it on everything he used develop O two thousand of the
yeah just a little studio that used to be a closet in his
house it's now we have a little a that's in
a a lot though uh california
and he's developed
two thousand of these videos a cover basically everything technical indicator a K twelve curriculum
like kids education and now we starting to move in the things is very excited move in just circuits in
the other areas
he an unbelievable teacher
you might worry that you know a are you gonna lose your job to sell car right
a so the idea of little video tutorials little six minutes seven minute and it tutorials on a on a
concept
or on
for example do use how to get started with lab of you or how to get started in this lab
are are tremendously powerful both as a a a a just support distance learning for dealing with students were not
in your campus
uh also as time savings the training a lot of people who have
lattice
and are teaching kids about matlab or a you will use a video tutorials in advance
so they don't have to go over the material and class
and then also really interesting ideas like reversed instruction anybody or reverse destruction
where you basically what all of the lecture materials
right you have a regular
classroom setting but all the lecture materials are available by
video
students are expected to watch those in advance and the only thing that goes on during the class
is actual discussion problems so
right of jeffrey herman
whose that a postdoc at university of illinois actually talk
that you want U C D S P class
using this system a laugh summer
and it was it tremendously a sec
i tremendously
and uh the actually one the best paper word that at S P and uh concert
a last that
last
last
any any comments or questions about
we jump by no rose home folks
i've done a lot with with
videos to great effect
any comments mark
wait
a
read this paper
so how many people here have ever experimented with this kind of
as way put it upside down a classroom or reversed
instruction
but here played around with it
i would expect were all pretty traditional
"'kay" so there is there are increasing numbers of experiments going on with this and
increasing amount of evidence
that this is a very very
a highly effective way to teach
and the thing is very difficult or challenging to all of these you the out there is that it really
cuts against the grain of what were used to do it
which is
going to the board
writing for an hour
and then having having students uh right at yeah
but there was just a very
interesting paper it came out of sight
a i i think that it should before for last by
a group uh U B C vancouver
uh uh uh where they actually showed
and entire letter a great improvement
in the class
a a a a a a that the class outcomes learning outcomes
uh by doing this
basically reversed model
jim
a high high
get yeah
i yes it to change anything great go one
a if a
yeah
so the jury still out
the jury is still have
okay
the last thing i'll say for moving on is this
doing this kind of thing used to actually be really hard
is very hard but
tools now like yeah
can't ages do O which you can and and so other tools
which are either very inexpensive or even in some cases
for
to use are uh make it really really quite easy to do this
oh enough about a
video to as the next is
try to bring the lab work to the elements of the laboratory
in to the classroom into the home study experience in the homework work
uh using a interactive to simulation
and the idea here is to move from us C culture right a printed attack
more towards that a do culture
um i actually interacting with a a a a a different kinds of stimulation
and there as as as everyone knows as a number of different environments out there there's a to are acting
with we probably missed several
um but every from from land you mathematical a a a um man at to
a three a J D S P
a there are uh
also a number of other platforms that people are developing
a and you can actually bill
extremely elaborate
and and very interesting uh uh a simulation is an examples of let people all
real world times of problems
a a uh in a very very got efficient manner is one a yours right
wait
or not we marks right
it's it up
a basically a a convolution demo and a filter
filter design them all that less students get a handle on
uh
that
parameters and all the various different filter structure
i i'm sure everybody here
male and will add you are met and that one of these two but what it
coming is much much easier ways to put these kind of
uh simulations up on the web making the i've
for your class to use and and folks around the world
you
so any comments about this
and the simulation how many people here
are using the
in their class
like
jim did you have a content
are years
okay my make a
do
absolutely so there's a
yeah building anything like this is always a tradeoff between
look and feel and he's a of construction
and and
all three of these sort of
industry standard tools have to different models for how to do this kind of thing
different ways to put to distribute them and put them up on the web and so
the jury is still out as far as which of these as the best the number of the us
still
a actively experimenting with and then i i hopefully by the community
in yeah working more more with all of these will put pressure on these vendors to
get even better right then
J he's P taken for the
yeah
yeah
right
oh we you got work so i'll does give you yes or our personal experience
is we have work a lot over the years
a a putting lad you
black these simulations in
and uh just do two
it it's just become a little bit more tricky lately to put a be since in people still are doing
this
and work also experimenting this summer
there now is a clear path
to put a at the added to simulations directly in any web page connections pages or any web page
and then you get into this
trade-off the jim kind of alluded to
that uh
mathematical looks like at least today it's close we change at least day
this is the easiest to get
to produce content to put in a web page
but it is by far and least flexible as far as look and feel
and design
all i
feel free to talk to the aft
like i so you it
more about
but there is
some free
how an increasingly easy
a a a a ways to do this
yeah yeah
one one are and there's also some ways a have again it's just a trade of
design look and feel
he's
yeah
exactly
jim one work coming
right exact
yeah yeah yeah you these are fairly
i
so based thinking of these not as just a stand alone
a a of feet here
but really as a laboratory
that's to needs to are it actively engage it's some kind of activity well doing
yeah one
yeah
right
hmmm L for one yep
i
a remove on
okay K people
so uh
i i another uh
error error E R okay so we talk about the led lecturing talk about the text work
talk about the lab
so now what about the old works right an exam so there's data
number projects
actively engaged in
developing data bases of of questions and answers
to to uh for the purposes of a
storing but then also share
on a much broader uh a base than on in institutional base
and and these question as to data bases have a lot of applications
self assessment problems for students so they can understand how well they're doing a in the class
a automated work systems
that take a lot of the pressure off graders and instructors for grading sold work
and also provide immediate feedback to the student on
whether they did a problem correctly or incorrectly which is been prove and again
to to to enhance learning
when you have immediate feedback rather than the usual least rice
two weeks later you get a homework work back
a a great
a so all this mentioned to
data bases that are being developed the the first and and largest is
a a start like to mcclellan that's the signal processing uh a question response system at georgia tech they have
actually well over a thousand problem
right M
i think
a a signal processing problems by a number of different faq of the uh a at georgia tech
a a we are right they're developing a a a a a a a and of this that we can
look quite base
it's a a just has a slightly different uh a slightly different architecture but the good thing is that using
a web standards like you T I
which is the
think of it like the each T M L our the X M L for marking ah
uh problems in answers
a a it's gonna actually be very quite straightforward
once all the details are worked out to move the problems back and work
tween mean different databases and also directly into your
learning management system
right if the use a a a black or or or a mood or or and an exact
and and a moving forward over the the the next two years we're gonna see just like we just talk
one second ago
ways and means to track student progress
as it work to their home works as they work through not just a semester course the through their tired
curriculum
and both
jim's group my group but a number of other folks are actually actively started to work on
uh intelligent tutoring systems coding systems for
a a a a a a teaching people signal process
they can either we use
justin said like
separated from an actual structure or we in the context of a of the regular class
uh
just some couple screen shot is the S P Q R looks like a
presents a problem uh let's a student C where they are in the course and how they are doing right
like the dashed dashboard
i here the top
uh so it's very much of course they
it's a course organised
a a base and the other hand is just intended to be super light weight place
for community to develop and share question
right and uh under these creative commons
like
a so that this is that to the two databases bright no there some other people work
that's some work
so T
in common
wayne in comments audience comments but database
and
oh okay okay okay
a a a a
does the one question and how many people here we would uh
use problems if they were up but that were up a database instead of invading
there or
okay
i many people here would kick screwed you one of their own problem
okay how many people would be here the big one
i we people it would be worried
if the answers were also i'm their publicly available
only a few people work
okay
so
kind
oh
that
right one good point to point
okay i was ahead the last
key element is
how do we deal with the just to manage all these people in our community developing all all diverse set
of educational
resources is right diversity means what
all kinds of levels of quality so how are we gonna can dock some kind of evaluation of these but
you
as you uh
well i think people red
as quickly as i
a so how don't we uh bring in some of the mechanisms that we we use are very familiar with
the ieee
in particular peer review
are we bring in some of these is are used for for gauging quality but then how do we also
a a balance
the exclusivity of a peer review
with the what we really like to be something more community based or inc
so uh what we've done in in a
a a a project in collaboration uh S P society and and connections
is to develop a sad of we call lenses as
which is essentially a
a peer review system for material thing connection it could also be applied to simulations
could be applied his video tutorials to be applied to this question is a data
the basic idea behind a how it works
is is a big blue D here is the entire
connections repository of eighteen thousand modules and all of these text but
there's little kids readers in here there's really good signal processing stuff there may be really bad signal process
stuff stuff
so what as P society has out
is all lan
i don't land is is simply a web sort all there's the address you go to ieee see an X
dot work
you will get to look in the connection is but you will only see the stuffing connections
that the ieee
right the P society has actually evaluated input their stamp
this makes sense to everybody
so just to give us a sense of how this
how this works
let's say you're in google you wanna learn about detection theory
you type and detection theory you end up in this connection one to right have you written by don john
you don't know done
you don't know if it's any good could be crappy right
a a a a a but if you notice over here there is a little a land and on that
says that this material but endorsed by the S P society we you click on that link
in actually take heed of a less them all of the materials
that have undergone
quality evaluation by yeah
i
and you see don a piece of uh material
right so you can think of this as a
really
parallel time to kind to the
editorial boards in us it's to develop this idea of a a a land
two point in a high quality at a content in the connection we've actually built a open source version a
script central if you well that enables us to handle the
a all the administration high this call
i
a a there is a a a a P add technical can maybe have a committee
that you can think of at be a editorial board for this up particular peer review process
i think there's really to or or things that were trying to do here the first is help you user
find the high quality stuff
and the second as you as a potential author
be able to earn endorsed by to fully so that we can move toward the world where educational materials have
a
uh a a a some of the same kind of a cash a as
usual close words
and zero okay
or blurring the lines
cool
uh
comments about this
know or couple is or what
oh can so let me just and by saying
a there's is actually a a project started by a number of us
called the signal processing education work
is actually training with and the staff national science foundation support and ieee
collaboration to pull together all of these
uh i S and we uh it's X library thing right georgia tech you cat
and uh rows home and to to technology and we're really trying experiment but all of these different elements and
bring them together into a one
a a system
where everything is then again a quality review by a the i-th i
hi only in i invite everyone to participate
a a through the the ieee project the links at the bottom
contributing your material
also also becoming coming a pure are much like be a review or a paper
and also invite you to join
uh the then project
we intend to
grow this nationally internationally over the next
do you years
there's is a a workshop scheduled schedule twenty the september georgia tech
and you like to participate a a a a you're welcome and please get to a tight side of a
gym or to mcclellan or my cell
a for more information
so so with that probably should and in case we have a
a couple last
questions are con
a
i
i
um i one or more
one want or oh
or
you
yeah
but
