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
