  4. problem •theory • DME• results •conclusion 1. What’s the problem? • High expectations concerning the integration of technology into mathematics education have not yet come true. • Growing awareness that teachers are crucial in the integration of technology into mathematics education: • Gueudet & Trouche (2009) • Lagrange & Monaghan (2009) • Lagrange & Ozdemir Erdogan (2009) • Maracci & Mariotti (2009) • Pierce & Ball (2009) • Ruthven, Deaney & Hennessy (2009) • Issue at stake: what do teachers do when they integrate technology in their teaching and why do they do so?

  5. Didactical performance Exploitation mode Didactical configuration problem •theory • DME• results •conclusion 2. Theoretical framework • Instrumental orchestration as a model for analysing teacher activity (Trouche, 2004; Drijvers & Trouche, 2008) • An instrumental orchestration: the teacher’s intentional and systematic organisation and use of the various artefacts available in a learning environment in a given mathematical task situation, in order to guide students’ instrumental genesis. • An instrumental orchestration: • a didactical configuration • an exploitation mode • a didactical performance

  6. Didactical performance Exploitation mode Didacticalconfiguration problem •theory • DME• results •conclusion Didactical configuration • A didactical configuration is an arrangement of artefacts in the environment, a configuration of the teaching setting and the artefacts involved in it. • Cf. the musical metaphor: • choosing the musical instruments to include in the orchestra • arranging them in space and time to achieve harmony (= convergence of mathematical discourse).

  7. Didactical performance Exploitation mode Didacticalconfiguration problem •theory • DME• results •conclusion Exploitation mode • An exploitation mode is the way the teacher exploits the didactical configuration for her didactical intentions: decisions on the way a task is introduced and worked, on the possible roles of the artefacts, and on the schemes and techniques to be developed. • Cf. the musical metaphor: • determining the partition for each of the musical instruments involved.

  8. Didactical performance Exploitation mode Didacticalconfiguration problem •theory • DME• results •conclusion Didactical performance • A didactical performance involves the ad hoc decisions taken while teaching, on how to actually perform in the chosen didactic configuration and exploitation mode: what question to pose now, how to do justice to (or to set aside) student input, how to deal with an unexpected aspect of the task or the tool? • Cf. the musical metaphor: • the actual musical performance

  9. problem •theory • DME• results •conclusion The orchestration model ... • has a time dimension: ranging from teachers’ preparation in advance (didactical configuration) to ad hoc decisions while teaching (didactical performance) • has a structural – incidental dimension: ranging from teachers’ operational invariants to incidental actualizations • Includes two levels of instrumental genesis, namely the students’ level and the teachers’ level, the latter being the focus of this talk

  36. problem •theory • DME• results •conclusion Teacher profiles Teacher A: • prioritizes student-centred orchestrations • sees learning as an interactive process in which students should have a voice • sees technology as a means to achieve this ”…so you can have discussions with the students using the images that you saw on the screen, … that makes it more lively”

  37. problem •theory • DME• results •conclusion Teacher profiles Teacher B: • prioritizes teacher-centred orchestrations • finds mathematical content to be paramount • sees technology as a means to teach this • attention to the links between the DME-work and paper-and-pencil or blackboard mathematics. ”… take distance from the specific ICT-environment; otherwise the experience remains too much linked to the ICT”

  38. problem •theory • DME• results •conclusion Teacher profiles Teacher C: • prioritizes teacher-centred orchestrations • finds clear explanations and instructions important • has a concern for student difficulties when learning mathematics, and when using technology ”As a teacher, one has to tell students clearly what they should do with ICT”

  39. problem •theory • DME• results •conclusion Teacher profiles Teacher D: • prioritizes student-centred orchestrations • leaves much initiative to the students • does not see a technology-rich lesson as a specific one to prepare “Well, I don’t know much about it myself. I did not invest time in preparation. […] I prefer the kids act, and raise questions based on their actions.”

  40. problem •theory • DME• results • conclusion Conclusion • Which types of instrumental orchestration emerge in technology-rich classroom teaching? Seven orchestration types are identified, as well as their frequencies. • To what extent are teachers’ repertoires of orchestrations related to their views on mathematics education and the role of technology therein? The four teacher profiles suggest a clear relationship between orchestrations and views.

  41. problem •theory • DME• results • conclusion Reflections • How generalizable are the orchestration types, to other topics, to other types of technology, to other forms of teaching, to other teachers … ? • Why such a preference for individual orchestrations in Study II? Do teachers feel that they should step back as soon as technology enters the classroom? • What are possible implications for teachers’ professional development concerning ‘TPACK’? • What does the model of instrumental orchestration offer? A fruitful framework for analysing teachers’ practices when teaching mathematics with technological tools?
