A Tamil Nadu version of Khan Academy?

From Peter Appelbaum, here is a report from southern India about a series of online teacher demonstration videos designed to function as a textbook

two things ...

Two things about our group I have been thinking about:

(1)  Looking at our last day, I noticed that none of us produced an *actual* textbook page. Are all different things we discussed (internet, books/not textbooks etc.) a good excuse for us not to commit to a written page? Things aren't fluid on a written page, we have to make decisions, defend them, and being authors, take responsibility for their consequences.



(2) I'm not at all comfortable eliminating an *expert* from the picture (implicitly present in internet context, not just wikipedia).

text/book projects with a focus on AREA (AIRE)

Wikipedia & iTunes U.

Link to the Textbook entry on Wikipedia

Wikibooks - open content textbook collection that anyone can edit

Wes proposed that the textbook for any course would/could/should be the link to Wikipedia.

iTunes U. - learn anything, anywhere, anytime

Monday Morning Discussion of Sunday's Work

1. Wes: Wikipedia is "best" textbook available - not because of what's written, but because of what is not written - missing points, question marks, edited comment that "this does not suffice" etc., so the reader is left to fill in these places on their own.

Peter: book from the 70s where at least a third of the page is left blank for students to comment and fill in their remarks; the book with the student comments became the final book.

On-line textbooks make this collection of meta-comments part of what will be the textbook.
We discussed also the ways that internet sets of reviews and links (through algorithm) to other books/films/etc.... for us we might think of reviews by other teachers, students, ...

Juxtapose: Literature (ex: the one version of Shakespeare's Romeo & Juliette). Textbooks direct the attention of the person toward what y ou want them to do.

2. Peter : Reprise of idea that textbook is collaboration of artist and the reader. A textbook might be like the painting of Olympia, looked at an hour a week, studying historical context, extending, technique, where does it take us...
Online might allow for this in a different way. For the teacher to control the wealth of thing, harness it all, turns teaching into curating materials??
Online, student can overwhelmingly find new things and input them. This might change the relationship among teacher, text and student: teacher does not have to see everything, even though a teacher's acknolwedgement and interaction is powerful and important.
Control has to be let go, loosened, allowing others to collaborate on the curatorship.

3. Lucie: Smartboard... imagine teacher presents algorithm/explanation. Record content of smartboard; then students listen later and in the class have textbook as resource on problem solving. Students go on blog of teacher. Always start from problem solving.
Compared with BC consumable workbooks as textbook, changes year by year. No explanations, no worked examples. Big/small questions. Teacher does what Lucie described.

4.Miroslav: start with objectives. Course starts with list of questions we want student to be able to answer at the end. Course itself creates a textbook that does it.
Kathy, Peter & Osnat: create course around only problems. Ideally students create the problems but we're not sure if the problems would be good enough or lead to the right outcomes. Final exam: they create the questions, not answering them.
The tension between teacher and student knowing what questions to ask might be a false issue if we see it in a more interactive and dynamic way. e.g., after students ask some, a teacher might react with a question based in his or her own agenda for objectives; or, learning about asking questions includes looking at other mathematicians' questions and thinking about them, too.

Lucie: this indicates the importance of the domain / big ideas in mathematics, makes it easier to invite students to make their questions.

Joan: teachers create text(books); this can serve as data in research about teachers' understanding, relationship with/to students, texts, expectations for textbooks, etc. etc.

Introducing fractions in Magnitskii's Arithmetics in the early 18th century in Russia

Since 2004, we work with my colleague Alex Volkov, on exploring didactical value of mathematics textbooks, old and modern ones. We look at conceptual approaches that authors represent in their books. Our latest publication for the ICME-12 is now awailable online:  http://www.icme12.org/upload/UpFile2/TSG/0703.pdf
We look at fractions in the first Russian arithmetics textbook written by Magnitskii in the beginning of the 18th century. While some authors point at the origins of the book from earlier European medieval texts, others claim original didactical ideas of introducing concept of fraction. The paper belong to the TSG35 on the History of mathematics teaching and learning and there are other interesting contibutions on textbooks development.

 

Agenda for our Third (Final) Morning


  1. Reports from yesterday: online textbooks and non-textbooks and anti-textbooks
  2. Small Groups (Majority of our time): creating a text/book in more than one way based on ideas from this working group experience. Proposed Focus: Area (AIRE)
  3. Contributions to our working group report to the larger community (30 minutes) - what should others hear/know about what we have been working with and discussing? What might others experience through our report?

Peter Taylor's publications and textbooks available online

.

Peter Taylor, Queen's University, publications

characteristics of textbooks

Peter, Kathy, & Wes:
1. Textbooks versus reference books
2. Textbooks can be collaboration between artist and teacher who collects a number of works that are compiled and put together into a textbook for the course.
3. Needs a pedagogical aim.
PROPOSED DEFINITION: collaboration between artists and a teacher. The teacher might be the one to insert the pedagogical aim.Typically, though, the author(s) assign the pedagogical aim.
Textbooks might tend toward de-skilling if they are comprehensive in designing the text for a particular aim.

Addressivity (Joan, Barbara, Lucie ):
1. Books with rich mathematical content could be made into a text if ... 
2. Just as one can disrupt the canonical text, that becomes a different invitation.
3. Author's intention for a canonical textbook:
  a. make money
  b. share their ideas about explaining, helping people learn, that they believe would benefit teachers and students

POWER OF GENRE: takes on cultural life of its own, molds peoples' intentions to conform to the needs of the genre. However a textbook writes in the textbook genre, pushing the boundaries, etc., the genre itself has a formatting power, the intentions encoded in the genre in a way take over and overpower the authors' intentions.

Textbooks are simultaneously constraining & enabling for teachers.

Genre Analysis

Susan introduced how you need to know the genre well to play around with it... an example is from
Davis & Rinvolucri,  Dictation: new methods, new possibilities, who turned DICTATION upside down. Another book by them is about language labs.

A method for doing genre analysis, by Susan Gerofsky (reprise from earlier post)

Genres by their nature are not "definable"...

1. Existence/patterns: what is/isn't a textbook? how can you tell?
2. Chronotype: setting, place, time ... and math?
3. Addressivity: how does the textbook imagine its audience and position its audience and itself?

Susan's burning questions


1) Intentionality and uptake of the genre
How does the mathematics textbook genre format math classrooms, math students and teachers, math learning and teaching? What is the formatting power of the textbook?

How does the existence and use of textbooks affect the relationship between other mathematics ' resource books' and math textbooks?

How do students learn to read/not read math textbooks? (For example, does anyone read the preamble or introduction for the reader? Are students aware of the topics of units of work -- do they read the table of contents or chapter headings?  How do students read word problems?)

How do teachers learn to read/not read/ use mathematics textbooks? Is mathematics teaching 'meant to be' performing the textbook/

2) Addressivity of the genre:
What is the addressivity of a math textbook -- how does it position its imagined audience?

Where is there space for learners and teachers to enter the world created by a mathematics textbook?

3) Chronotope of the genre
Why do math textbooks tell us so much about their chronotope (ie: setting in time, place, culture) rather than about mathematics?

4) Archaeology of the genre
What other things are math textbooks like? What do they remind us of?

How did the math textbook genre develop/ emerge historically? Do old math textbooks or those from differing cultural contexts seem the same or different?


Peter's burning questions

1) Identifying textbooks as opposed to something else
What is a textbook, and how is that different from using something as a text with students?

2) The intransigent nature of the text as codification of the discipline
Despite the documented successes of non-standard uses of textbooks (e.g., students critiquing rather than using, re-writing ...) and disruption of the authors and audiences for the texts (students making their own textbooks for themselves and others, different groups of students comparing different texts as resources for their own learning, ...), the place of the textbook and its positioning of teachers and students persists. Why, how, and in whose interests?

3) Textbooks are sites of work-life struggle
Text materials are commonly used to de-skill teachers (they become cogs or conduits rather than designers of experience). When teachers approach their work creatively, responding to the lives of their students, this is often considered inappropriate. What are the implications?

4) People need to see the textbook to know what the curriculum "is" - or else?
Isn't anything and everything in one's lifeworld a mathematics textbook? Why does this not so easily translate into understanding everyone as a mathematician whose "inner mathematician" has been thwarted from expression by school mathematics?

Institutionalized Text
o   Gates, Peter, Markets, Marx, Modernity and Mathematics Education. A Response to Michael Apple

(a)  Less experienced teachers tend to more fully implement packaged curriculum materials?
(b)  The existence of text materials implies that they were developed by people “who know”.
(c)   Texts “qualify” teachers and students in Foucauldian senses, skilling and deskilling these participants in particular ways, while establishing social and cultural norms at individual, group, school, district, provincial, national, and other levels of analysis.
(d)    Texts position readers and teacher-readers as “needing a text” – i.e., as someone who cannot perform their role without a text or without the assistance of a text.

·         International Text
o   Which works are most useful here?  
(a)  On the one hand, mathematics is commonly taken as a universal/transnational and transcultural language.
(b)  One the other hand, ethnomathematical approaches help us see how (Western, Ameroeuropean) mathematics is a form of global imperialism that denies indigenous forms of mathematics while raping the cultural landscape for new mathematical concepts and models.
(c)

o   Skovsmose, Ole – which references of many are relevant to mathematics “texts”?
(a)  Conceptions of (critical) “competence” and relations of power
(b)  Foregrounding the question, “What knowledge is of most worth?”, and to corollaries, “Who gets to decide? How does this matter/make a difference?”
(c)   Mathematics education as/for social justice

·         Poststructuralist, Deconstructed, Postmodern Text
o   Appelbaum, Peter Embracing Mathematics
(a)  Mathematics contributes to an understanding of no fixed selves, truths, mirroring of reality, conceptions of knowledge, value, or moral codes; flux over stasis.
(b)  Ethics replaces morals in the interrogation of how mathematics and mathematics education contributes to the establishment of ideological commitments and institutional structures of social and cultural reproduction
(c)   Institutions work in strategies of maintenance; forms of resistance and social change manifest themselves in tactics, poaching, perruque

·         Theological Text
(a)  Platonic mathematics might be a substitute for religion; infinity for god; historically, conceptions of infinity have brought people closer to god
(b)  Intellectual “cleansing” via mathematics and logic is sometimes related to a spiritual cleansing via baptism, purging, etc.

Comments: Ralph Tyler's Basic principles of Curriculum and Instruction (1949) set up expectations for curriculum development that have been either worshipped or challenged ever since:
Start with objectives (determined by the content/subject, by the needs of students, and by social needs)
Collect experiences that will help learners meet these objectives, an
Then build in ongoing assessment to help you make sure you are meeting the objectives along the way.
To be a textbook, must a "book" be designed in this way? Did the geneaology of textbooks inform his approach to curriculum? A century later, are we still acting out his fantasies and fears in our creation and use of textbooks?
