1 00:00:00,050 --> 00:00:07,549 Okay, good evening ladies and gentlemen. As you can probably guess, we're going to be talking about the technology design process in this video. 2 00:00:08,410 --> 00:00:16,269 And what I'd like you to understand is that almost all forms of technology, while they're being developed, undergo this process. 3 00:00:16,629 --> 00:00:23,129 It's a step-by-step process that most technology follows while it's being developed. 4 00:00:24,050 --> 00:00:29,309 So for this evening's homework, I'd like you to not only watch the video, 5 00:00:29,309 --> 00:00:38,210 but simply jot down very quickly the steps that you have uncovered while watching the video 6 00:00:38,210 --> 00:00:42,850 so that I know that you watched the video and you're ready to do the assignment tomorrow during class. 7 00:00:43,270 --> 00:00:46,810 The first step of any technology design process is a need. 8 00:00:47,789 --> 00:00:54,070 And what I mean by a need is that the technology must have a reason to be developed. 9 00:00:54,490 --> 00:00:59,250 There's no purpose in developing technology if it's not going to serve us in any way, 10 00:00:59,390 --> 00:01:05,230 as it may cost a lot of money, a lot of time, for something that may not be useful. 11 00:01:05,870 --> 00:01:13,319 So if we look even around our classroom, one form of technology might be the clock. 12 00:01:14,260 --> 00:01:18,099 The clock, the need for the clock is to tell time. 13 00:01:18,439 --> 00:01:27,140 The PA system, in order to give us important announcements. 14 00:01:27,140 --> 00:01:35,140 If we look up at the air conditioner and the fan, their need is to keep us cool. 15 00:01:35,140 --> 00:01:39,140 Pencil sharpener, so that we can write and record things. 16 00:01:39,140 --> 00:01:46,620 Even a chair and a table has some sort of need. 17 00:01:46,620 --> 00:01:50,620 It allows us to be organized, it allows us to be comfortable while we're learning. 18 00:01:53,120 --> 00:02:00,439 Okay, so when we look at this chart, it brings up five important points that we're going to discuss over the next couple days. 19 00:02:01,099 --> 00:02:09,919 So if we look at starting with the top left, ask, we need to ask a question and determine what our need is. 20 00:02:10,699 --> 00:02:12,300 And then we need to think about it a little bit. 21 00:02:12,300 --> 00:02:15,819 We need to imagine what we can develop in order to answer our question. 22 00:02:16,759 --> 00:02:21,500 Okay, after we have imagined, we've come up with an idea, we need to plan our idea. 23 00:02:22,319 --> 00:02:31,900 Then we design or build our idea, and once we have tested our idea, then we try to improve it based on the problems that we've witnessed. 24 00:02:32,099 --> 00:02:38,759 So just as a reminder, as we go through the video, make sure you're jotting down the important steps to the technology design process. 25 00:02:39,419 --> 00:02:46,900 We talked about the ask, imagine, plan, create, and improve steps. 26 00:02:47,699 --> 00:02:54,539 As we go through it, I'm going to add a little bit of detail, so be sure to add to your list a little bit as I go through. 27 00:02:54,960 --> 00:03:02,879 Okay, so if we put a little bit more detail into this, we can see that our ask, imagine, plan, create, and improve steps, 28 00:03:03,319 --> 00:03:08,659 we must ask some questions and try to generate a solution by developing our technology. 29 00:03:09,139 --> 00:03:15,360 So when we ask, we want to ask, what is the goal? Why are we creating this technology? What is the need? 30 00:03:15,960 --> 00:03:20,879 When we imagine, we're looking at what the technology will look like 31 00:03:20,879 --> 00:03:22,659 and what kind of research should we do. 32 00:03:23,780 --> 00:03:29,580 When we plan, we're going to think about how we can accomplish the goal most efficiently. 33 00:03:30,699 --> 00:03:33,939 When we create, we're going to build a prototype or a model 34 00:03:33,939 --> 00:03:36,099 and observe if problems occur. 35 00:03:37,060 --> 00:03:39,860 And to improve, we're going to test that model or prototype 36 00:03:39,860 --> 00:03:43,680 and generate solutions or fixes to the original prototype. 37 00:03:45,360 --> 00:03:52,939 Okay, let's take a look at an example that will help you trace through the technology design process. 38 00:03:53,360 --> 00:03:55,699 We're going to look at the example of a car. 39 00:03:56,319 --> 00:04:04,139 Now, if you look in the picture above, this is what most people thought of as a car, 40 00:04:04,300 --> 00:04:10,180 an early prototype of a car back in 1800s, early 1900s. 41 00:04:10,539 --> 00:04:15,159 And compared to what we have today, things have changed. 42 00:04:15,159 --> 00:04:29,160 So today when we think of a car, we think of something that is much more high tech. When we say high tech, it's because we went through the whole technology design process several times over to develop the current cars we have now. 43 00:04:29,160 --> 00:04:46,079 So people asked, how can we make the car better? They imagined, oh, what if we could have reclining seats or a CD player or a trunk to store things? They planned. They came up with a model that they thought could accomplish their goal. 44 00:04:46,079 --> 00:04:51,079 They created a prototype and the prototypes continued to develop. 45 00:04:51,079 --> 00:04:55,079 And then they went back and they tried to solve problems. 46 00:04:55,079 --> 00:04:59,079 They improved their design and created a new design. 47 00:04:59,079 --> 00:05:04,079 So now we have multiple different cars, multiple different structures 48 00:05:04,079 --> 00:05:08,079 that enable us to accomplish the same goal 49 00:05:08,079 --> 00:05:14,079 but are more conducive to everyone's needs or desires.
