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
