1 00:00:00,012 --> 00:00:07,950 It has been so great working with all of you over the last 12 weeks. 2 00:00:07,950 --> 00:00:14,725 >> The goal has to been to learn how to evaluate and analyze arguments. 3 00:00:14,725 --> 00:00:22,409 >> Now, something totally new. >> You get to construct your own argument. 4 00:00:22,409 --> 00:00:28,706 This is an experiment. >> You all submitted around 400 arguments. 5 00:00:28,706 --> 00:00:35,799 >> And thousands of extremely helpful comments on each others arguments. 6 00:00:35,799 --> 00:00:42,159 Woah, that was great. >> Our heartfelt thanks to all of you. 7 00:00:42,159 --> 00:00:50,026 >> There were many, many, many, many, many, many, many wonderful arguments. 8 00:00:50,026 --> 00:00:57,255 >> An emotional roller coaster. >> I laughed and I cried. 9 00:00:57,255 --> 00:01:03,845 >> It was so hard to pick which ones to discuss this week. 10 00:01:03,845 --> 00:01:13,127 >> They all deserved discussion. >> We were so sad that we couldn't discuss 11 00:01:13,127 --> 00:01:19,160 them all. >> But we might use some of them the next 12 00:01:19,160 --> 00:01:26,108 time we offer this course. >> Still, how are we going to pick which 13 00:01:26,108 --> 00:01:32,621 ones to discuss this week? >> You all helped us with your votes. 14 00:01:32,621 --> 00:01:40,210 But, as Durval pointed out, the voting system, is biased. 15 00:01:40,210 --> 00:01:49,060 >> A fair election requires equal exposure to all the voters. 16 00:01:49,060 --> 00:01:55,635 >> As I write, there are 350 plus arguments in the discussion forum. 17 00:01:55,635 --> 00:02:06,698 >> If the voter spends one minute reading each one of them it would take them over 18 00:02:06,698 --> 00:02:14,132 six hours to read them all. So voters are not going to read them all. 19 00:02:14,132 --> 00:02:19,808 Spaker: Threads, in the first pages will have more views. 20 00:02:19,808 --> 00:02:25,195 >> By default, the first pages show top threads. 21 00:02:25,195 --> 00:02:31,780 The ones that are most replied, most voted up and most commented on. 22 00:02:31,780 --> 00:02:39,258 >> Threads posted recently. Go to the end of the queue, thus receiving 23 00:02:39,258 --> 00:02:46,236 less attention and less votes. Therefore, this voting system is biased. 24 00:02:46,236 --> 00:02:52,949 Wow, what a wonderful argument! No wonder this received over 100 votes 25 00:02:52,949 --> 00:02:59,430 from other students. >> But it says that these very votes are 26 00:02:59,430 --> 00:03:00,669 biased. Hm. 27 00:03:00,669 --> 00:03:08,106 That's self refutation. >> Anyway, we're convinced by Duval that 28 00:03:08,106 --> 00:03:16,070 the voting system was imperfect. But of course, >> Imperfect does not mean 29 00:03:16,070 --> 00:03:22,328 totally worthless. >> The votes were affected by many factors 30 00:03:22,328 --> 00:03:28,585 other than quality. >> This whole poll repeats the lesson that 31 00:03:28,585 --> 00:03:33,346 we learned >> In week six. About bias sampler. 32 00:03:33,346 --> 00:03:40,454 Because this whole voting method, is just another example of a bias way to sample 33 00:03:40,454 --> 00:03:47,983 student opinions about whatever. >> So we used several other considerations 34 00:03:47,983 --> 00:03:52,344 to decide which argument we're going to discuss. 35 00:03:52,344 --> 00:04:00,202 >> The first thing we considered was your votes, because we wanted to hit the topics 36 00:04:00,202 --> 00:04:06,294 that interested you. >> The second thing we considered was the 37 00:04:06,294 --> 00:04:13,054 quality of the arguments submitted, because we want to provide helpful models 38 00:04:13,054 --> 00:04:15,876 of good. >> Argumentation. 39 00:04:15,876 --> 00:04:20,867 >> The 3rd thing we considered was distribution, because we'd like to make 40 00:04:20,867 --> 00:04:25,718 the lectures this week be an overview of all the different things that we've 41 00:04:25,718 --> 00:04:31,692 covered in the course. And the fourth thing we considered was how 42 00:04:31,692 --> 00:04:39,882 useful the submitted arguments are in helping us to make new points that we did 43 00:04:39,882 --> 00:04:47,820 not have time to make in the course up until now, because there's a lot more to 44 00:04:47,820 --> 00:04:51,272 say. About reasoning and argument, than we've 45 00:04:51,272 --> 00:04:54,945 said so far in this course. Because we use all of these 46 00:04:54,945 --> 00:05:00,685 considerations, you cannot infer from the fact that we don't discuss your argument 47 00:05:00,685 --> 00:05:06,261 or don't discuss your favorite argument, that, that means that we don't think that 48 00:05:06,261 --> 00:05:11,700 argument's any good. We had to pick in ways that, even we don't 49 00:05:11,700 --> 00:05:16,369 like. So please don't think, that simply because 50 00:05:16,369 --> 00:05:20,737 yours isn't included, that we didn't like it. 51 00:05:20,737 --> 00:05:25,951 We did. >> And besides, the point of this course 52 00:05:25,951 --> 00:05:33,000 is not to win, but to learn. So enjoy the videos this week, as we look 53 00:05:33,000 --> 00:05:37,231 back over the 12 weeks of think again.
