What Students Need: Exploring Teachers' Views via Imagined Role-Playing (original) (raw)

Lesson Play tasks as a creative venture for teachers and teacher educators

This study focuses on instances of creativity in the design of Lesson Play tasks and in prospective teachers’ responses to the tasks. A Lesson Play task assumes a theatrical interpretation of the word ‘play’ and requires teachers to write a script for an imaginary interaction between a teacher-character and student-characters, attending to a particular instructional situation. These instructional interactions are triggered by ‘prompts’ that present an unexpected student claim, or a particular erroneous conclusion or reasoning. I present a brief overview of the various iterations of task development. I then demonstrate instances of creativity in the design of Lesson Play tasks by teacher educators and in responses to the various prompts in the tasks by prospective teachers. The prompts for the plays and teachers’ responses to the tasks are analysed using an extension of Lev-Zamir and Leikin’s model of Creativity in Mathematics Teaching. While the original model attends to teacher-directed creativity and student-directed creativity, the proposed extension attends to mathematics educators in the role of teachers, and teachers in the role of students. I illustrate cases of pedagogical flexibility and originality as well as of mathematical creativity and originality, noting that multiple facets of creativity can be recognized in particular instructional choices. I conclude that Lesson Play tasks present a fruitful avenue for displaying and supporting teachers’ creativity.

A curious case of superscript (−1): Prospective secondary mathematics teachers explain

In mathematics the same symbol – superscript (−1) – is used to indicate an inverse of a function and a reciprocal of a rational number. Is there a reason for using the same symbol in both cases? We analyze the responses of prospective secondary school teachers to this question. The responses are presented in a form of a dialogue between a teacher and a student and are accompanied with participants’ commentary on their choices of instructional approaches. The data show that the majority of participants treat the symbol ☐−1 as a homonym, that is, the symbol is assigned different and unrelated meanings depending on a context. We discuss how knowledge of advanced mathematics (or lack of it) can guide instructional interaction.

Script writing in the mathematics classroom: Imaginary conversations on the structure of numbers

Script writing by learners has been used as a valuable pedagogical strategy and a research tool in several contexts. We adopted this strategy in the context of a mathematics course for prospective teachers. Participants were presented with opposing viewpoints with respect to a mathematical claim, and were asked to write a dialogue in which the characters attempted to convince each other of their point of view. They had to imagine and articulate fictional characters' reasoning, as well as design a potential pedagogical intervention. We outline what script writing revealed about the participants' understanding of the structure of natural and rational numbers and of mathematical argumentation, and discuss the affordances of this methodological tool in teacher education.

Virtual Duoethnography

We introduce virtual duoethnography as a novel research approach in mathematics education, in which researchers produce a text of a dialogic format in the voices of fictional characters, who present and contrast different perspectives on the nature of a particular mathematical phenomenon. We use fiction as a form of research linked to narrative inquiry and exemplify our approach in a dialogue related to various proofs of infinitude of primes. We view Lakatos' (1976) dialogue in the seminal Proofs and Refutations as an example of virtual duoethnography. We discuss the affordances of this approach as an alternative to the formal ways of presenting research in mathematics education.

Prospective Teachers' Conceptions of Proof Comprehension: Revisiting a Proof of the Pythagorean Theorem

A significant body of research literature in mathematics education attends to mathematical proofs. However, scant research attends to proof comprehension, which is the focus of this study. We examine perspective secondary teachers’ conceptions of what constitutes comprehension of a given proof and their ideas of how students’ comprehension can be evaluated. These are explored using a relatively novel approach, scripted dialogues. The analysis utilizes and expands the proof comprehension framework of Mejia-Ramos, Fuller, Weber, Rhoads & Samkoff (Educational Studies in Mathematics, 79, 3–18, 2012). We suggest that this expansion is applicable to other studies on proof comprehension.
