Listen: Chris, Twitter, Dan Leith discussed on Mr Barton Maths Podcast
"And when the previous license to go coupla days before we stop in utopic to react to this stuff that it can't do Dame, maybe t- Cady or two days to keta fix that period stuff for those you need the stanchion for before beginning lesson. You went in shorts and never. Perhaps of prompt and. Painting way we are what we're doing. And it may be that the staff is a question on the board or some statement or some fine. On the, the people's ghetto put you need to inquire about. It's conjecture. Ten problem did not race again topical fan. So, so Vinnie creations probably, but did not rate, the beginning of solving equations, but teeth as maybe license often Chretien's by license sex or seven. They have enough knowledge that ever teach them Qena, a follow on from that. And if teaching the principles is opposed to proceed if you get this, thank Shen, what actually what's going to win? How you do this. Then I think quite often that evil just take statement or less crazy of giving them in this author a name and then run with lot as a star all that next Partha the secrets. Got it. Got it fascinating this let me just before. We move onto specific tasks design. Let me just one more thing about features in your lesson. And the reason I wanna ask you about what your example, problem Pez look like. And the reason I'm twenty this is I have very definite way that I do these now being very fortunate this year having a sabbatical from my job of being able to visit lots of other schools and watch lessons and speak to teachers. I'm very much aware that there's lots of different varieties in how teachers do example, problem as even though we're we're all kind of calling them the same thing and listeners. If you haven't checked out my interview with Michael Persian that I am I recorded which will probably be the episode before, before this one that you listening to be available. Now he blew my mind with how he does example problem has. So Chris just again, is the colors you like, what, what, what is your example problem pep process? Lot line. Using these toll. Here's I think experimental with teacher a half. Thing that to be well perceived, it's perhaps more successful with 'em over gets the younger kids and of how to help focus their tension. Maybe just the nature of some of the classes of the practical for years. I don't know. So just like what you modal before good free one, but I'm not talking of the top of as it, but I'm gonna rate, Elaine, watching him cope with lane a Nanno, discuss lot, light them. Get what I'm saying? We can't get through. I'm conscious not just talk over the top of it. But meets sure less than when I'm talking sure that apply. Coin types. With each lane that I want a name repeat. The few takes Eggen through. Like I said, the LA road, one of the things I've been looking. In about more bite was fading and I don't know. I don't know a famous spoken, but that they have. A little, I'm always fascinated. Dif- different takes going. What, what do you perceive it to mean? And how do you how do you incorporates it? Chris. What are you struggling envy's lak- and what she would do 'em equation? And you're using one of the, the double angle formula, and they're saying to x two to make a substitution. Right. So all that walking is first of all, making substitution then your rear engine and taking equals zero. Then you're factor. Eating, and then you get to definite equations is your and your Sovan each of these trick. Occasions may individually. If you're doing that top lane that bet, which is a Saint Jack me, cores aches, for instance. That's the you bet. So. Ben. Well, how'd you win? As subsitution UCF that use that used to court square aches, Angus one, the one minister saints act which opposition figures ran so that more teaching on where she by the, by the ball on the example like solvent through some Polonia, equations can already do otherwise wouldn't be doing this, this topic. Eighty s license. What we do is at what one in Phil. Let them walk one. I guess the one and I do my half the ball. The meshing, right. They will do next and side at what I four lanes, Dan. At first, I led to the to then I would do the foster lades it three a net only have the fuss lane. So what what's happening sometimes that can speed the upper level? But she how much back if bucket four. But what the in getting direct teaching when that you bet bet the decision making process, the bet this unfamiliar to them is Beck where you're getting more examples on. What the fraction is a that's. It's obviously going because actually stuff of creation is easier. Bets is all amasses like that which start with something complicated in review steadier and each lane. You. This is actually a problem from funky taking your gracious planes, simplified version. What do that will give them maybe four or five questions to this entire? Give them a short king grow for nap today, insure with Nikki candidate as a see something that usually recent in his cabin experimented with it. The I knew in teams of somebody studies or not. And fix that fix is over actually being more to than Josh. No. Unprepared. Bills, try this kinda just hurry into ju can I just just on a practical level. That is it still an example problem para in the sense that when you do it Thursday. And so you do four lines and leave out the fifth line student still then have a problem to complete on, on the right inside the board or wherever it is, or is it enough of them just to complete the fifth line. If that makes sense L the always pad up these these backwards. Fading with eight years of gully. Right. I see. So when your when you then leave out the bond, two lines, the still then another complete one for them to do if that makes sense curate. So I've never had five closures to on the first one, I would just do all than I would do the full slogans the night street next to witty appeared. I see. Which is why I'm suggesting we have maybe four or five questions after which they're doing their tire Goths and offend thus in genetic do. Many people does so. That's an interpretation of its definitively. No, no. It's fascinating. And again because I I've read the research on on the button with fade in as well. And it's just I'm always fascinated about practically. What does that look like in the classroom out of people find that worth? So that's something I'll definitely, I'll definitely moreover. And well, if with you, Chris, we will we might turn to come to the main thrust of what I wanted to talk to you about, which is which is test design. And I know that you're working on a book currently with, with mcchord about Tostes. I know that from following you on Twitter. I think your your one of said this on the podcast before your one of the best and use of Twitter I've ever seen in the sense that you will, you will create an activity or task, and you'll just throw it out there on Twitter, and you will copy in people who have radically different views. So you'll you'll copy into the mic your copy of my Colloton, your copying Chris Bolton your crop curb copy in Watson. And you'll just say what people think of this, and you get some. Useful suggestions. So I'm I'm fascinated by tusk design is something that I'm really thinking hard at, at the moments, whether it's through my variation theory, whether it's my kind of fill in the gap activities as the mass vans, whatever it is. I'm I'm really interested in the thought process that goes into into Tostes line. So trying to get the ball rolling. Chris walden. What did you approach to test design used to look like before you started researching and thinking, really how would you create or choose tasks in the past? Well. Pardon me. Porgies. Shamefully. It's not it's not even we should overcame and thought the procedures. Thank courtships in behavior that thinking, but teaching at the beginning, I was thinking about procedures, Dan Leith. I was thinking procedures in coincidence, Christus spe concepts mathematical behavior. So as involved as a teacher. Task device. People used to do highs evolved. So initially. You'll look if for good, what sheets made against practices off looking for WALE questions with a nice can't creating of an increase definitely Aena. You're looking for. And then perhaps at looking for something wet. Back then with engaging for them and maybe not necessarily actually I did not much earlier. So I think call enjoying Beijing talks that an attack versus. Osa. Thirsk. And that is the task is to ask people to actually do the Egner task is undergoing. Thank you vote win. The doing. What Saint Michel have potential end is become. And stuff in the past back when it knows random things with the days of they, they just didn't do it. And they went advice is just, just another what she dressed up and finally close it wasn't actually moving forward. The conceptual understanding. So they're not saying you begin to think, snowflake into those units, some of the milk was once off, Wayne look at some of the stuff doing steers website, these these of the that next kennel up. Click you begin to cooperate stuff of that elk. And, and then more recently is looking at tasks, which is poised give an opportunity. For people to elevate themselves from I have of even not. So it's not just pure application. It's actually inquiry. Which will laugh just talking about the rights. Instructional as you see the still placement choir here. Acquire an I posting quietly with an e inquiry Fanie, e asking questions and baking you stuff is referred fame. But inquiry what Franken into something to get you into it. Is something which is, is quite hard to evade defict scale it to the classroom, we let coach on people's during that. So I work, and I think sampling the land, this would please, Ed. So we can not so task the same before enemies, it would involve basically a lot of team. It was generating what sheets because I look over scholar, stakes hide Bill it. None of these treat Walker Evans properly. None of them have had a. It's I some things metastasis. We'd be fought copy before five takes taking question when from that, but creation for not Burke, gracious, ex and making sheet. But isn't it? With Justice officiant practice of the scale that wasn't highlight stuff and. Then occasionally began coin matching casks and things spot that extent metastasis end the past. I've been told for five years ago, wasn't see anything. Great. I was just us walk it. Signed. And we some nice takes poops behind, which were the massive action say one in two and ace one cubed in two kids and Scotland. A duty as challenge questions and them and the what proof in this. That was quite quite demanding. So I, I often news good body than an awful Qena practice. Catch to end the public supplemental. So that was that was what it was before an author people stage. The whole kit was was terrible. Yeah. You're right. And I got if I my approach the kind of choosing toss was was exactly go on the tests. Find a five star resorts and just try and like look what I'm teaching find a five-star source and that was the activity, I was going to use, and I'd say, what even worse than you, Chris more often than not. I wouldn't even do it myself before I think this is this is one of the biggest things I've learned at whether it's an excess, whether it says series of questions, whether they vary not or whether it's an a rich so-called rich Tosco, whatever if you don't do it yourself before you are the absolute trouble. And in. Is just so obvious. So obvious to say, but I just didn't do it. It was part of my lesson. Plumbing process wasn't actually doing the activity that I was going to give the kids and classic cousin knowledge things, sometimes I'd be so cocky, to think that I could just glance at the tippety or series of questions and judge within five seconds. Whether there was any twists or turns, whether it was gonna appropriate and so on. And so you can, you can get a certain amount of information from that. But he's only when you sit down and do a task or sequence. Acquire DD get to uncover some of these potential sticks dynamite that a look in that, that they're going to blow things up unless you can -ticipant them is that something is that a mistake you made as well. Chris not actually do auditees types tons. Basically student teacher was not. I was teaching high mass clients undecided. Make sure you don't exercise before you do if we teach it and the student, but they didn't teach in the courses made me. So. I knew tons of people who would do that. Stealing my Stoffel. I'll be yet. Yep. It wasn't a people do. It was a bit making sure I had prepared them for every question. It's amazing it begin with Salty's it. And it may be a an exercise on. Some care polio. Cuff."
