0:00:00.000,0:00:09.120 music 0:00:37.720,0:00:44.800 Well, we could ask ourselves what the purpose of an educational system is 0:00:44.800,0:00:50.550 and of course there are sharp differences on this matter. 0:00:50.550,0:00:54.010 Now, there's the traditional interpretation 0:00:54.010,0:00:57.469 that comes from the Enlightenment 0:00:57.469,0:01:04.320 that holds that the highest goal in life is to inquire 0:01:04.320,0:01:12.160 and create, to search the riches of the past, 0:01:12.160,0:01:18.720 and try to internalize the parts of them that are significant to you 0:01:18.720,0:01:24.126 and carry that quest for understanding further in your own way. 0:01:24.126,0:01:33.971 The purporse of education from taht point of view is just to help people to get their own help, to learn 0:01:33.971,0:01:35.968 on their own. 0:01:35.968,0:01:41.400 It's you, the learner, who is going to achieve in the course of education. 0:01:41.400,0:01:47.480 It's really up to you what you'll master, where you'll go, 0:01:47.480,0:01:57.160 how you'll use it, how you'll go on to produce something new and exciting for yourself, maybe for others. 0:01:57.160,0:02:00.813 That's one concept of education. 0:02:00.813,0:02:03.460 Now the other concept is essentially indoctrination. 0:02:03.460,0:02:08.290 People have the idea that from childhood 0:02:08.290,0:02:19.600 young people have to be placed into a framework in which they'll follow orders, 0:02:19.600,0:02:24.360 accept existing frameworks, and not challenge. 0:02:24.360,0:02:26.680 And this is often quite explicit. 0:02:26.680,0:02:37.440 For example, after the activism of hte 1960s, there was great concern 0:02:37.440,0:02:42.052 across much of the educated spectrum 0:02:42.052,0:02:48.800 that young people were just getting too free and independent, 0:02:48.800,0:02:52.640 that the country was becoming too democratic and so on. 0:02:52.640,0:02:59.160 There was an important study on what's called the crisis of democracy, too much democracy, 0:02:59.160,0:03:08.640 claiming that there are certain insitutions responsible for the indoctrination of the young-- 0:03:08.640,0:03:13.120 that's their phrase-- and they're not doing their job properly. 0:03:13.120,0:03:18.160 That schools, universities, churches---we have to change them 0:03:18.160,0:03:22.223 so that they carry out the job of indocrintation and control more effectively. 0:03:22.223,0:03:25.080 That's actually coming from the liberal internationalists 0:03:25.080,0:03:31.480 end of hte spectrum of educated opinion. 0:03:31.480,0:03:34.720 In fact, since that time there have been many measures taken 0:03:34.720,0:03:42.520 to try to turn the educational system towards more control, more indoctrination, 0:03:42.520,0:03:45.360 more vocational training. 0:03:45.360,0:03:53.680 Imposing a debt which traps students, young people, into a life of conformity. 0:03:53.680,0:04:01.760 That's the exact opposite of what I referred to that traditionally comes out of the enlightenment. 0:04:01.760,0:04:03.760 There's a constrant struggle between those. 0:04:03.760,0:04:13.817 In the colleges and the schools, do you train for passing tests? 0:04:13.817,0:04:18.368 Or do you train for creative inquiriy? 0:04:18.368,0:04:25.892 Pursiung interests that are aroused by materil that's presented, you want to pursue either on your own 0:04:25.892,0:04:27.120 or in cooperation with others. 0:04:27.120,0:04:34.120 And this goes all the way through up to graduate school and researh. 0:04:34.120,0:04:37.680 Just two different ways of looking at the world. 0:04:37.680,0:04:42.600 When you get to a research institution like the one we're now in, 0:04:42.600,0:04:49.640 at the graduate level, it essentially follows the enlightment tradition. 0:04:49.640,0:05:05.969 In fact, science couldn't progress unless it was based on inculcation of the urge to challenege, to question 0:05:05.969,0:05:17.000 doctrine, question authority, search for alternatives, use your imagination freely of your own impulses. 0:05:17.000,0:05:22.130 Cooperative work with others is constant as you can see just by walking down the halls. 0:05:22.130,0:05:28.280 That's my view of what an educational system should be like down to kindergarten. 0:05:28.280,0:05:34.809 But there certainly are powerful structures in society 0:05:34.809,0:05:42.053 which would prefer people to be indoctrinated, to conform, to not ask too many questions, to be obedient, 0:05:42.053,0:05:51.062 to fulfill the roles that are assigned to you and not shake systems of power and authority 0:05:51.062,0:06:01.140 Those are choices we have to make, wherever we stand in the educational system. 0:06:01.140,0:06:07.520 As students, as teachers, as people on the outside trying to help shape it in the direction that we think it ought to go. 0:06:07.520,0:06:21.806 Well there certainly has been a very substantial growth in new technology-- 0:06:21.806,0:06:33.040 technology of information, communication, access interchange. 0:06:33.040,0:06:37.967 It's surely a major change in the nature of hte culture and society. 0:06:37.967,0:06:44.654 We should bear in mind that the technological changes that are taking place now, 0:06:44.654,0:06:51.574 while they're significant probably come nowhere near having as much impact 0:06:51.574,0:06:57.200 as technological advances of a century ago. 0:06:57.200,0:07:02.200 Let's take communicaiton. 0:07:02.200,0:07:08.640 The shift from a typewriter to a computer or a telephone to email is significant. 0:07:08.640,0:07:20.645 But it doesn't begin to compare with a shift from a sailing vessel to a telegraph. 0:07:20.645,0:07:27.360 Tge time that that cut down in communication between England and the United States 0:07:27.360,0:07:31.884 was extraordinary as compared with the changes taking place now. 0:07:31.884,0:07:34.484 The same is true of other kinds of technology. 0:07:34.484,0:07:42.080 The introduction of widespread plumbing in the cities had a huge effect on health, 0:07:42.080,0:07:45.908 much more than the discovery of antibiotics. 0:07:45.908,0:07:48.200 So the changes are real and significant, 0:07:48.200,0:07:53.571 but we should recognize that others have taken place that were much more dramatic. 0:07:53.571,0:07:58.819 As far as the technology itself and education is concerned, 0:07:58.819,0:08:04.995 technology is basically neutral. 0:08:04.995,0:08:06.481 It's kind of like a hammer. 0:08:06.481,0:08:11.822 The hammer doesn't care whether you use it to build a house 0:08:11.822,0:08:15.909 or whether a torturer uses it to crush somebody's skull. 0:08:15.909,0:08:17.905 A hammer can do either. 0:08:17.905,0:08:22.320 Same with modern technology, say, the internet, and so on. 0:08:22.320,0:08:27.280 The internet is extremely valuable if you iknow what you're looking for. 0:08:27.280,0:08:30.320 I use it all the time for research, I'm sure everyone does. 0:08:30.320,0:08:35.880 If you know what you're looking for, you have a kind of framework of understanding 0:08:35.880,0:08:39.825 which directs you through particular things 0:08:39.825,0:08:46.745 then this can be a very valuable tool. 0:08:46.745,0:08:48.881 Of course, you always have to be willing to ask 0:08:48.881,0:08:50.413 "Is my framework the right one?" 0:08:50.413,0:08:52.040 Maybe I have to modify it." 0:08:52.040,0:08:57.920 Maybe if there's something I look at that questions it, I should rethink how I'm looking at things." 0:08:57.920,0:09:08.897 But you can't pursue any kind of inquiry without a relatively clear framework 0:09:08.897,0:09:14.887 that's directing your search and helping you choose what's significant and what isn't. 0:09:14.887,0:09:17.720 What can be put aside, what can be pursued, 0:09:17.720,0:09:20.971 what ought to be challenged, what ought to be developed. 0:09:20.971,0:09:25.801 You can't expect somebody to become a biologist 0:09:25.801,0:09:35.040 by giving them access to the Harvard University biology library 0:09:35.040,0:09:37.120 and say, "Just look through it." 0:09:37.120,0:09:40.080 That'll give them nothing. 0:09:40.080,0:09:43.494 The internet is the same except magnified enormously. 0:09:43.494,0:09:47.320 If you don't undertsand or know what you're looking for, 0:09:47.320,0:09:51.320 if you don't have some kind of conception of what matters-- 0:09:51.320,0:09:56.497 always with the proviso that you're willing to question-- 0:09:56.497,0:10:03.649 if you don't have that, exploring the internet 0:10:03.649,0:10:08.897 is just picking out random factoids that don't mean anything. 0:10:08.897,0:10:16.885 Behind any significant use of contemporary technology-- 0:10:16.885,0:10:22.643 the internet, communicaitons systems, graphics, whatever it may be-- 0:10:22.643,0:10:33.120 unless behind it is a well constructed, directive, conceptual apparatus, 0:10:33.120,0:10:37.643 it is very unlikely to be helpful. 0:10:37.643,0:10:39.120 It may turn out to be harmful. 0:10:39.120,0:10:43.913 For example, random exploration through the internet 0:10:43.913,0:10:48.040 turns out to be a cult generator. 0:10:48.040,0:10:51.900 You pick up a factoid here, a factoid there 0:10:51.900,0:10:53.920 and someboyd else refers to it, 0:10:53.920,0:10:58.820 and all of sudden you have some sort of crazed picture 0:10:58.820,0:11:02.256 which has some factual basis but nothing to do with the world. 0:11:02.256,0:11:05.920 You have to know how to evaluate, interpret, and understand. 0:11:05.920,0:11:09.920 Say biology again. 0:11:09.920,0:11:13.402 The person who wins the Nobel prize in biology 0:11:13.402,0:11:18.742 is not the person who read the most journal articles and took the most notes on them. 0:11:18.742,0:11:20.800 It's the person who knew what to look for. 0:11:20.800,0:11:25.894 And cultivating that capacity to seek what's significant-- 0:11:25.894,0:11:30.240 always willing to question whether you're on the right track-- 0:11:30.240,0:11:34.080 that's what education is going to be about. 0:11:34.080,0:11:38.805 Whether it's using computers and the internet or pencil and paper and books. 0:11:38.805,0:11:59.285 Well, education is discussed in terms of whether it's a worthwhile investment 0:11:59.285,0:11:59.785 Does it create human capital? 0:11:59.785,0:12:05.229 It can be used for economic growth and so on. 0:12:05.229,0:12:14.981 And it's a very distorting way to even pose the question, I think. 0:12:14.981,0:12:22.226 Do we want to have a society of free, creative, independent individuals, 0:12:22.226,0:12:28.217 able to appreciate and to gain from the cutlural achievements of the past, and to add to them? 0:12:28.217,0:12:30.817 Do we want that? 0:12:30.817,0:12:34.560 Or do we want people who can increase GDP? 0:12:34.560,0:12:37.640 It's not necessarily the same thing. 0:12:37.640,0:12:49.811 An education of the kind that ---- John Dewey and others talked about, 0:12:49.811,0:12:51.040 That's a value in itself. 0:12:51.040,0:12:56.731 Whatever impact it has in the society, it's a value 0:12:56.731,0:13:00.840 because it helps create better human beings. 0:13:00.840,0:13:04.000 After all, that's what an educational system should be for. 0:13:04.000,0:13:06.320 On the other hand, if you want to look at it 0:13:06.320,0:13:09.734 in terms of costs and benetifs, 0:13:09.734,0:13:15.818 take the new technology that we were just talking about, where did that come from? 0:13:15.818,0:13:19.400 Well, actually a lot of it was developed right where we're sitting, 0:13:19.400,0:13:27.056 Down below where we now are was a major laboratory back in the 1950s, 0:13:27.056,0:13:29.360 where i was employed in fact,. 0:13:29.360,0:13:39.223 Which had lots of scientists, engineers, people of all kinds of interests-- 0:13:39.223,0:13:40.560 philosophers, others. 0:13:40.560,0:13:47.815 Who were working on developing the basic character and even the basic tools 0:13:47.815,0:13:51.480 of the technology that has now come. 0:13:51.480,0:13:53.520 Computers and the internet for example, 0:13:53.520,0:13:58.840 were pretty much in the public sector for decades, 0:13:58.840,0:14:04.400 funded in places like this, where people were exploring new possibilities 0:14:04.400,0:14:08.898 that were mostly unthought of, unheard of at the time. 0:14:08.898,0:14:10.895 Some of them worked, some didn't. 0:14:10.895,0:14:14.982 The ones that worked were finally converted into tools that people could use. 0:14:14.982,0:14:18.976 Now that's the way scientific prgress takes place. 0:14:18.976,0:14:23.062 It's the way that cultural prgress takes place generally. 0:14:23.062,0:14:28.800 Classical artists, for example, 0:14:28.800,0:14:33.976 came out of a tradition of craftsmanship that was developed 0:14:33.976,0:14:38.680 over long periods with master artisans, with others. 0:14:38.680,0:14:47.211 Sometimes you can rise on their shoulders and create new, marvelous things. 0:14:47.211,0:14:51.902 But it doesn't come from nowhere. 0:14:51.902,0:14:59.982 If there isn't a lively cultural and educational system 0:14:59.982,0:15:06.205 which is geared towards encouraging creative exploration, 0:15:06.205,0:15:16.760 independence of thought, williingness to challenge accepted beliefs. 0:15:16.760,0:15:24.560 If youdon't have that you won't get teh technology that will lead to economic gains. 0:15:24.560,0:15:32.537 Though that I don't think is the prime purpose of cultural enrichment in education. 0:15:32.537,0:15:56.480 There is in the recent period particularly an increasing shaping of educaiton 0:15:56.480,0:16:03.930 from the early ages towards passing examinations. 0:16:03.930,0:16:12.120 Taking tests can be of some use, both for the person who is taking the test-- 0:16:12.120,0:16:16.920 seeing what I know, and where I am, and what I'm achieving-- 0:16:16.920,0:16:23.620 and for instructors--what should be changed and improved in developing 0:16:23.620,0:16:26.640 the course of instruction. 0:16:26.640,0:16:29.480 But beyond that, they don't really tell you much. 0:16:29.480,0:16:36.299 I mean I know for many many years, I've been on admissions committees 0:16:36.299,0:16:42.880 for entry into and advanced graduate programs-- 0:16:42.880,0:16:45.215 maybe one of the most advanced anywhere-- 0:16:45.215,0:16:50.602 and we of course pay some attention to test results, but really not too much. 0:16:50.602,0:17:00.215 A person can do magnificently on every test and undrestand very little. 0:17:00.215,0:17:05.138 All of us who've been through schools and colleges and universities 0:17:05.138,0:17:06.531 are very familiar with this. 0:17:06.531,0:17:14.920 You can be in some course that you have no interest in 0:17:14.920,0:17:18.466 and there's demand that you pass a test, 0:17:18.466,0:17:20.920 and you can study hard for the test, 0:17:20.920,0:17:24.240 and you can ace it. 0:17:24.240,0:17:29.612 And a couple of weeks later you've forgotten 0:17:29.612,0:17:31.376 what the roptic was. 0:17:31.376,0:17:32.630 I'm sure we've all had that experience. 0:17:32.630,0:17:33.720 I know I have. 0:17:33.720,0:17:39.132 It can be a useful device if it contributes 0:17:39.132,0:17:43.219 to the constructive purposes of education. 0:17:43.219,0:17:46.376 If it's just a set of hurdles you have to cross, 0:17:46.376,0:17:49.627 it can turn out to be not only meaningless, 0:17:49.627,0:17:52.367 but it can divert you away from things that you want to be doing. 0:17:52.367,0:17:56.320 I see this regularly when I talk to teachers. 0:17:56.320,0:18:00.541 If you want an epxerience from a couple of weeks ago-- 0:18:00.541,0:18:06.299 I happeneded to be talking to a group which included many schoolteachers. 0:18:06.299,0:18:09.120 One of them was a sixth grade teacher 0:18:09.120,0:18:12.200 who teaches kids who are ten or eleven. 0:18:12.200,0:18:18.374 She came up to me aferwards and I'd been talking about these students. 0:18:18.374,0:18:24.132 She told me of an experience that she had just had in her class. 0:18:24.132,0:18:30.640 After class a little girl came up to her and said she was really interested 0:18:30.640,0:18:35.371 in something that came up and she asked if the teacher could give her some ideas 0:18:35.371,0:18:37.042 of how she could look into it further. 0:18:37.042,0:18:39.364 And the teacher was compelled to tell her, 0:18:39.364,0:18:41.680 "I'm sorry, but you can't do that, 0:18:41.680,0:18:46.080 you have to sutdy to pass this national exam 0:18:46.080,0:18:49.320 that's coming that's going to determine your future." 0:18:49.320,0:18:51.680 The teacher didn't say it, but it's going to determine my future, 0:18:51.680,0:18:57.522 whether I am rehired. 0:18:57.522,0:19:01.470 The system is geared to getting the children to pass hurdles, 0:19:01.470,0:19:04.680 but not to learn and understand and explore. 0:19:04.680,0:19:10.061 That child would have been better off if she had been allowed to explore 0:19:10.061,0:19:14.960 what she was interested in and maybe not do so well on the test about things she wasn't interested in. 0:19:14.960,0:19:19.760 They'll come along when they fit into her interests and concerns. 0:19:19.760,0:19:26.547 So, I don't say that tests should be eliminated, 0:19:26.547,0:19:30.123 they can be a useful education tool. 0:19:30.123,0:19:35.975 But ancillary--something that is helping improve ourselves, 0:19:35.975,0:19:39.550 for instructors, and others, what we're doing--tell us where we are. 0:19:39.550,0:19:52.368 Passing tests doesn't begin to compare with searching and inquiring, 0:19:52.368,0:19:59.080 into pursuing topics that engage us, excite us. 0:19:59.080,0:20:02.720 That's far more significant than passing tests. 0:20:02.720,0:20:09.133 In fact, if that's the kind of educational career 0:20:09.133,0:20:11.200 that you're given the opportunity to pursue, 0:20:11.200,0:20:14.380 you'll remember what you discovered. 0:20:14.380,0:20:17.680 (Someone) is a world famous physicist 0:20:17.680,0:20:27.720 right here at MIT who was teaching freshman courses. 0:20:27.720,0:20:28.280 He once said that in his freshman course, 0:20:28.280,0:20:36.720 students will ask, "What are we going to cover this semester?" 0:20:36.720,0:20:38.480 And his standarad answer was, 0:20:38.480,0:20:42.560 "It doesn't matter what we cover, it matters what you discover." 0:20:42.560,0:20:43.963 That's right. 0:20:43.963,0:20:49.840 Teaching ougth to be inspiring students to discover on their own. 0:20:49.840,0:20:55.387 To challenge if they don't agree. 0:20:55.387,0:20:59.120 To look for alternatives if they think they're better ones. 0:20:59.120,0:21:05.046 To work through the great achievements of the past and try to master them on their own 0:21:05.046,0:21:06.360 because they're interested in them. 0:21:06.360,0:21:12.560 If that's the way teaching is done, 0:21:12.560,0:21:19.211 students will really gain from it and will not only remember what they've studied 0:21:19.211,0:21:22.800 but be able to use it as a basis for going on their own. 0:21:22.800,0:21:25.062 And again, education is really aimed 0:21:25.062,0:21:31.471 at helping students get to the point where they can learn on their own. 0:21:31.471,0:21:35.464 Becuase that's what you're going to do for you life. 0:21:35.464,9:59:59.000 Not just absorb materials that are given to you from the outside and repeat it.
