What I appreciate most about your post ...Deirdre, <br /><br />What I appreciate most about your post and following dialogue is that you never lose sight of the fact that we teach children before subjects. Perhaps what’s most interesting about teaching is what children bring to the disciplines that we take up. A great problem of concern here is the negative feelings and self perceptions that so many students seem to experience under a curriculum that values a single form of knowledge. What the current curriculum successfully does is engage children in the actual “doing” of mathematics; that is exploring relationships, wrestling with concepts and thinking critically about the how and why behind mathematical concepts, as opposed to arriving at one answer, one way. The excitement that erupts in my classroom when children discover relationships, uncover something previously hidden or experience an “ah ha” moment is incredible. Deep understanding is borne in these moments. <br /><br />Thanks for such a thoughtful piece. <br />Kari Siruphttp://www.blogger.com/profile/01910767809645313575noreply@blogger.comtag:blogger.com,1999:blog-1078744261633073420.post-50562912234795670942014-01-29T18:52:15.631-07:002014-01-29T18:52:15.631-07:00AWESOME post!! love it!
Mr. Craigen, you said &qu...AWESOME post!! love it!<br /><br />Mr. Craigen, you said "Just so you know, I don't share this contempt. My view is that parents are the most important stakeholders and we do well to listen to their voice", is this true in your courses in the university? Do you listen to the parents of the grad students in your class? <br /><br />While I agree that parents are important, I wonder why you put them above the the students in your class? How much do you allow parents to influence your doctorate courses?<br /><br />Next you address the survey as being signed by 1000s of Albertans. I have asked you many time for this proof? You always dodge the question. I am sure that this question is being signed by many outside the province, but I don't have any proof so I am wondering if you can step up and bring actual evidence?<br /><br />Also you claim that 1000 of her colleagues have signed this petition? I remember back to my undergrad class on statistics and how we need to know more than just simple numbers to create a correlation. Are these so called 1000 teachers from a certain demographic, community, etc?<br /><br />Dear Anna,<br /><br />I find it ironic that it is your opinion that most Educational papers are more on opinion than fact. You want students to understand math, however you force it to them through memorization. I think the point (and I may be wrong) is that we can't assume because a student has memorized a multiplication chart that they understand mathematics.<br /><br /><br /><br />Dave Martinhttp://www.blogger.com/profile/16805828337891203825noreply@blogger.comtag:blogger.com,1999:blog-1078744261633073420.post-92046091392927577412014-01-28T23:23:59.525-07:002014-01-28T23:23:59.525-07:00Hi Anna!
I received an email notification of your...Hi Anna!<br /><br />I received an email notification of your comment on my post Sunday morning but it did not appear on my blog and I couldn’t figure out why. I just realized that it had been filtered into the spam folder. I am not sure how this might have happened so my apologies for your comment’s belated appearance on the blog.<br /><br />I am grateful for your clarification that WISE wants kids to develop mastery of basic facts with understanding. I think in many ways we are not at odds and want to take the opportunity to clarify that I am not campaigning against algorithms at all. My concern is quite simply that when rote memorization shifts to the forefront in math education, it often becomes a substitute rather than supplement for the cultivation of deep understanding. I am simply advocating for pedagogical design that effectively allows students to develop an understanding of “why” as well as a mastery of “what” and “how” and that accounts for their individual differences by beginning with a question instead of a series of prescriptive instructions. While inquiry-based pedagogy is often misconstrued as “open exploration” or “discovery learning”, it is neither of these. Inquiry-based learning, effectively undertaken, is carefully and intentionally designed. It remains open as well as bounded and provides space for both repetitive practice and problem solving (see Galileo Educational Network).<br /><br />With respect to your comment about the articles I shared for further reading, please note that they were described as “a snapshot of academic research and writing.” Certainly I am aware they did not all constitute research specific articles. Of those that did, it is worth noting that your criticism of their validity is from the perspective of a mathematician. Your preference for RCTs is no surprise given your background. However as you are aware, educational research does not deal exclusively with numbers but with learning processes and children. While empirical evidence undoubtedly has its place, no amount of data can provide the information about classroom learning that field notes, interviews, conversations, photographs and recordings can. Issues of validity in qualitative research are not linked to sample sizes and control groups but to whether the researcher has made practices visible and therefore auditable and whether or not their work adheres to professional norms of peer review. This was the case for all of the research-specific studies linked above. While the nature of qualitative research is that it remains open to review, it is also worth noting that the criticisms you shared were webpages that do not appear to have been subject to peer review and could thus be perceived as less valid than the articles they critique.<br /><br />I agree that all graduate students in education would benefit from taking a sampling course from a statistician. I would add that perhaps all graduate students in mathematics with an interest in teaching might consider a course in educational research and qualitative methodologies. <br /><br />As Sharon writes at the conclusion of her “Teaching Math Better” article mentioned above “we have made demonstrable progress by working together - mathematicians, mathematics educators, and teachers.” I am grateful to have had the opportunity to engage in this conversation. Thanks for your comment!!<br /><br />Deirdre <br />Deirdre Baileyhttp://www.blogger.com/profile/13146089259718147219noreply@blogger.comtag:blogger.com,1999:blog-1078744261633073420.post-82634618101861261152014-01-28T20:59:11.792-07:002014-01-28T20:59:11.792-07:00Hi Deidre,

In discussing the "Math Wars" she writes "And this is where the crux of the disagreement lies, with one group of people believing that students need to spend a lot of time practicing, and the other group believing that it is better to understand an idea than it is to practice by rote" (Boaler, 2009, p. 37). On behalf of a proponent of the latter group, I want to thank you for championing our cause with great passion. <br /><br />Warm regards, Jen Jennifer Barkerhttp://www.blogger.com/profile/15919502616088044112noreply@blogger.comtag:blogger.com,1999:blog-1078744261633073420.post-36863935011677463932014-01-28T08:39:18.864-07:002014-01-28T08:39:18.864-07:00Hi Deirdre,
Your passion and ability to see the ...Hi Deirdre, <br /><br />Your passion and ability to see the beauty in mathematics, as well as in children's understanding of it, wherever that may be, is inspiring as an educator and makes me hopeful as a parent. As I watch my daughter engage in the world of quantity, number, and the manipulation of those things, I hope she has teachers in her life that will know her well enough to guide her through these concepts and charm her curiosity of them as well. As an educator, I see children walk through the door with a complete variety of background knowledge, and understanding of numbers. These same children think in very different ways, from each other and from me as well. Myself, as someone who was 'successful' in the current school system, I have come to realize that the way I have learned things is not always representative of the majority of our population. The care and accuracy of with which you speak addresses this variety and allows for different types of learners and thinkers to find their own success. Thank you for the inspiration.<br /><br />KellyUnknownhttp://www.blogger.com/profile/04170623882112630754noreply@blogger.comtag:blogger.com,1999:blog-1078744261633073420.post-32079874981487533682014-01-27T20:14:47.290-07:002014-01-27T20:14:47.290-07:00I think this is the type of study you're looki...I think this is the type of study you're looking for?:<br /><br />Thornton, C.

Children desire and deserve work that is deep, thought-provoking and worthwhile. I only wish that growing up I could have had even one math teacher as wise as you about the subject - Perhaps then my interest in math wouldn't have been killed by the lethal "old" math that forced me to memorize complex algorithms with no knowledge of why it was necessary. <br /><br />Thank you for sharing your important words.CarliMolnarhttp://www.blogger.com/profile/05081473248932675810noreply@blogger.comtag:blogger.com,1999:blog-1078744261633073420.post-79674591178843636612014-01-26T22:46:38.726-07:002014-01-26T22:46:38.726-07:00Thank you!

No memory, no learning. Those opposing memory work would do well to -- at minimum, acknowledge its importance (I presume you do not disagree, but I note that there is no hint of it in what you have written.) And, having acknowledged this, to explain why memorization of times tables is not a particularly good use of memory.<br /><br />I can tell you why, to the contrary, it is a good use of memory. <br /><br />Early-years learners are passing through a rapid acquisition phase during which important facts are committed to memory, establishing the foundation upon which later synthesis of cognitive understanding takes place. <br /><br />The ease with which these particular basic facts are automatized at this age contrasts the difficulty faced by those who must do so later in life -- students who fail to memorize these elementary facts at this stage may struggle mightily with them later, and many will simply fail in the effort and never master them.<br /><br />The goal of education is UNDERSTANDING. And understanding cannot grow in a vacuum -- it requires context. Context necessarily entails factual content about things, processes and relationships, committed to long-term memory.<br /><br />Our long-term memories are very well suited to storage and retrieval of such trivia. (Long-term) memory is not the ANTITHESIS of understanding -- it is an integral part of understanding. Understanding is functionally impossible without a well-stocked memory. I don't think any of this is controversial in the least.<br /><br />WNCP Math and the like forces children to adopt inefficient and ad-hoc mental approaches to even single-digit arithmetic, and in multiple ways.<br /><br />How different is memorizing multiplication tables from WNCP's rote work? "Rote" means "repetition". The demand for children to revisit the same "strategies" by rote in WNCP is simply astonishing. <br /><br />Grade 5 students are expected to "apply mental strategies" and use skip-counting, doubling, halving and looking for patterns, to "determine answers" (i.e. NOT facts they have yet mastered) "for basic multiplication facts to 81" (WNCP K-9 Framework, p104). <br /><br />"to 81" = "the 9x9 times table".<br /><br />Five years is FAR too long to force children to obsess over the mechanics of single digit arithmetic without closure! The 2008 NMAP report warns against "any approach that continually revisits topics year after year without closure", an indictment of WNCP Math, which specifies NO point at which these are to be mastered.<br />http://www2.ed.gov/about/bdscomm/list/mathpanel/report/final-report.pdf<br /><br />Now it doesn't take a PhD in brain function to know that working memory -- particularly for abstract facts -- is extremely limited. Famously, humans can reliably hold about seven digits in their heads but few can do the same with fourteen digits. It is a very small working space.<br /><br />A year ago a paper published in cognitive psychology quantified the rather obvious consequences. A team of researchers led by Dr. D. Ansari of UWO separated children according to whether they performed single-digit arithmetic with automatic recall or strategies. They collected longitudinal data on the same children years later from their SAT Math scores. Those who had, years earlier, committed the fundamentals to memory, significantly outperformed those who had been trained to use ad-hoc approaches.<br />http://www.jneurosci.org/letters/submit/jneuro;33/1/156<br />http://communications.uwo.ca/media/singledigitmath/<br /><br />Some contend that those ad-hoc approaches constitute "understanding". In fact the WNCP Framework itself, in outcomes specifying that children "demonstrate understanding of" such-and-such a concept, the corresponding achivement indicators specify that the children are to show multiple strategies. <br /><br />Yes, some call it "understanding". But I call it "clutter". R.

There's a lot there to consider and I want to make sure my response is thoughtful but I did want to clarify right away that I have absolutely no contempt or lack of regard for parents or parent voice in education. My introductory sentence was simply an acknowledgement of the petition and the dominant voice behind it. I do not agree that making children memorize multiplication tables in math classes is productive to their learning. Parent and other teachers' perspectives, although based on different experiences, are as important as mine to this debate. I remain open to further conversation on the topic and welcome feedback on the post. I think this debate is important and am sincerely hopeful that it can remain civil.<br /><br />With regards,<br /><br />DeirdreDeirdre Baileyhttp://www.blogger.com/profile/13146089259718147219noreply@blogger.comtag:blogger.com,1999:blog-1078744261633073420.post-15399455883420120762014-01-26T14:22:32.561-07:002014-01-26T14:22:32.561-07:00Hi Dierdre. I hardly got past your first line -- ...Hi Dierdre. I hardly got past your first line -- about the "parent-driven push". Your tone suggests that you think parents are ignorant of what's educationally best for their children and, not having Education degrees, are simply unqualified to address the issue as "stakeholders".<br /><br />As you surely know I have gotten deeply involved in this issue and I must say that I find it shocking to see the frequency with which those who've bought into trendy pedagogical theories speak down at parents in this way. You don't even bother to disguise your contempt for these supposed troglodytes, do you? Or perhaps you are simply unaware of it, it is such a seamless part of your worldview.<br /><br />Just so you know, I don't share this contempt. My view is that parents are the most important stakeholders and we do well to listen to their voice.<br /><br />I just clicked on the link you provided to Dr. Nhung Tran-Davies (the lowly "parent" in question -- a medical doctor). Her petition has attracted over 3500 signatures in a few short weeks. Many, even most, of the signers have added their own stories in their comments. For a petition dealing with the teaching of an academic subject in public schools, I would say that this is a remarkable phenomenon. Perhaps unheard-of in a jurisdiction the size of Alberta.<br /><br />In contrast, at the time I am writing this comment I see 3 (THREE) comments on your blog, though I see it is getting plenty of exposure through your friends in the Twitter-verse. Hmmm ... a 1000-to-one ratio. <br /><br />Now, obviously, truth is not determined by taking a straw vote. But let's just say that you're not doing a very good job convincing people. All your fine words weigh very meagerly against the effects people see on their own children, in front of their own eyes. You cite a lot of folks with fine-sounding theories. But theories are worthless if they can't stand up to empirical tests. Their children are the data points in the current empirical test.<br /><br />Proof ... meet pudding.<br /><br />One more thing you should consider. Perhaps you haven't bothered to do this yet: Go to the petition site, and just start reading all the public comments left by those who've signed. Notice how many EDUCATORS have signed the petition. Not a few. Not even "many" -- a LARGE fraction of those signing the petition are your fellow teachers. HUNDREDS of teachers. Perhaps over 1000. Many of these are parents, and see the same data points as the other parents. But even those who don't mention their own kids provide educational reasons for their support of Nhung's petition. <br /><br />I would think, even if you must look down your nose at the lowly parent-class, at least you would listen to your fellow educators. But perhaps you also have contempt for the many teachers who aren't so eager as you to "get with the program". Perhaps you think all those fellow teachers are troglodytes too.<br /><br />Again, I don't share this contempt. I think teachers are heros in this story and neither should their voices be ignored. <br /><br />Dr. Robert Craigen<br />Assoc.

First, I would like to point out that...Hi Deirdre,<br /><br />First, I would like to point out that my colleagues and I certainly want math to be taught with understanding! You would be hard-pressed to find a mathematician/math professor who does not want kids to understand math! However, we also want children to memorize times tables (which does not imply that they cannot understand multiplication) and to master standard algorithms. Furthermore, we want those algorithms to be taught with understanding. <br /><br />I am commenting on your blog because I want to address the issue of what you have listed as "research" articles. Having been at this for awhile, I have learned that what passes for research in education is often simply opinion. I suppose this makes me rather angry which is why I'm taking the time to post here.<br /><br />Of the articles you've cited, several do not involve any type of study at all (eg. Math: Teaching it better, Behind every jewel…).<br /><br />Several are based on case studies (eg. Raising the floor (one grade 7 classroom), Baroody (interviews with individual children)).<br /><br />None involve randomized controlled studies and sample sizes are all very small, with children treated as the experimental units as opposed to classrooms. As one example, the Caliandro article is based on a study in which there is no control group. <br /><br />Faulty conclusions are drawn in these articles regularly. For instance, the Caliandro article appears to be a study of procedures that students use if not given the standard algorithms. However, the authors make several conclusions that do not follow from the study they conducted. For example “Their procedures will not be forgotten. Memorized procedures, in contrast, are frequently forgotten and have to be reviewed again and again." This is an opinion and by no means follows from the study they’ve conducted. <br /><br />Probably the most prevalent problem in the algorithm articles is the false dichotomy that authors set up between standard algorithms and understanding. They seem to imply that standard algorithms are something to be memorized and not understood. Is it possible that the authors don't understand why the algorithms work themselves? <br /><br />For example, in the Caliandro article we see "In the standard multiplication algorithm, single digits are multiplied without regard to values the digits represent or why it is possible to break multidigit numbers apart and multiply single digits”<br /><br />Are the authors unaware that the standard multiplication algorithm hinges on the the distributive law???? If we want students to know why algorithms work, why not advocate for explaining why they work (this is not difficult to do) in conjunction with mastery, instead of campaigning against the standard algorithms?<br /><br />There are many other problems! As for Kamii, I am quite familiar with her work and have critiqued it before, as have several other mathematicians. Here is a critique written by Bill Quirk, which lists some of the problems: http://www.wgquirk.com/kamii.html<br /><br />Hung-Hsi Wu also mentions issues with Kamii's work in his piece Basic Skills vs. Conceptual Understanding: A Bogus Dichotomy in Mathematics Education: http://www.wgquirk.com/kamii.html<br /><br />I strongly feel that all graduate students in education should take a rigorous survey sampling course taught by a qualified statistician. Maybe this would eliminate some of these problems. On the other hand, a bit of critical thinking from an average citizen would quickly reveal the issues with most articles. <br /><br />Best regards,<br />Anna Stokke<br />Anna Stokkehttp://www.blogger.com/profile/10872865866449451008noreply@blogger.comtag:blogger.com,1999:blog-1078744261633073420.post-38591166988026160052014-01-24T18:15:32.710-07:002014-01-24T18:15:32.710-07:00This is beautifully written, Deirdre.
