Research Interests in Mathematical Music Theory (in construction)y

My interests are deterministic modeling of music analysis and structure and computational music analysis. I am particularly interested in modeling motivic (melodic) structure and analysis of musical compositions through a topological approach.

The motivic analysis of a music composition consists of identifying the short melody, called a motif, that units the composition through its strict repetitions, the so-called imitations, and its variations and transformations which are heard throughout the whole composition. Mainly using group theory, linear algebra and general topology concepts, we construct a (T_0-) topological structure corresponding to the motivic hierarchy of a composition. Our (computationnal topology) implementation (JAVA) , called *Melos *, can analyze music compositions such as Schumann’s *Träumerei *from *Kinderszenen *.

My ongoing interdisciplinary research mainly concerns:

- Concrete applications to a music corpus (recent works include
*Brahms' Op.51 No.1*and*Schumann's Kinderszenen)*

- A categorical extension of our model including e.g. continuous functions between two motivic spaces, products of different spaces, natural transformations (gestalt spaces);

- Visualisation of
*Melos’*multiple outputs in order to show and hear, and to explore mathematics and music results: now in our*OM-Melos tool*(see Buteau & Vipperman (2008));

- Cognitive experiments on melodic similarity in order to fix some parameters in the topological model.

Research Interests in Mathematics Education

My main interests in mathematics education are the use of technology in teaching and learning mathematics, and mathematics teacher education. I’m also interested in developing tools using music for the exploration of mathematics concepts.

I am currently involved in three research projects:

- Together with Dr. Daniel Jarvis (Faculty of Education, Nipissing University) and Zsolt Lavicza (Faculty of Education, University of Cambridge, UK), we have initiated (funded by SSHRC International Opportunities Fund Grants, 2007 - 2010) an international research project about the integration of Computer Algebra Systems (CAS)-based technology in undergraduate mathematics teaching. Our current research project includes three main parts: (1) a comprehensive literature review; (2) a national survey on Canadian mathematicians practices; and (3) two case studies of mathematics departments that have integrated and sustained over time the use of technology in its teaching. Related to our project, a
*Canadian Mathematical Society*(CMS) meeting session was recently organized (CMS Winter 2008 Meeting, Ottawa, December 2008):*Technology Use in Post-Secondary Mathematics Instruction.* -
Together with Dr. Joyce Mgombelo (Faculty of Education, Brock University), we have initiated (internally funded) a project aiming at investigating

*'Prospective Secondary Mathematics Teachers Repositioning, with Respect to Mathematics and Mathematics Didactics, by Designing and Implementing Mathematics Learning Objects*'. The project addresses the need for a better understanding of how prospective teachers of secondary school mathematics are shaped by their learning experiences during their undergraduate education. In traditional secondary school mathematics teacher education programs, students learn mathematics content in departments of mathematics and mathematics didactics in faculties of education. This division creates problems clearly identified by previous research (Adler & Davis, 2006), such as students missing connections between academic mathematics and mathematics didactics (Fernandez, 2006). In addition, in most programs students spend their first years of education focusing exclusively on acquiring subject matter knowledge and do not focus on teaching as a practice until their final years, which narrows the time devoted to didactics considerably and contributes to the disconnect between mathematics content and didactics.

Our project addresses the division between mathematics content and didactic practices, integrates didactics and mathematics content in prospective teachers' first years of education. It will create new tools to map changes in learning that future researchers can utilize, and will broaden the understanding of how departments of both mathematics and education can create programs that produce highly effective mathematics teachers.

The project reinforces the rich tradition of Brock Department of Mathematics of being actively involved with mathematics teacher education. -
Together with Eric Muller (Department of Mathematics, Brock University), we have been mainly working on practitioner reflections about the impact of Brock's
*Mathematics Integrated with Computers and Applications*(MICA) core undergraduate mathematics program on student mathematics learning. Our recent work concerns the student development process (task analysis) of the activity of designing, implementing, and using mathematics "*Exploratory and Learning Objects"*(done by our students in our 1st and 2nd year courses,*MICA I*and*MICA II*):

"

*An Exploratory Object is an interactive and dynamic computer-based model or tool that capitalizes on visualization and is developed to explore a mathematical concept or conjecture, or a real-world situation*and,

*A Learning Object is an interactive and dynamic computer-based environment that engages a learner through a game or activity and that guides him/her in a stepwise development towards an understanding of a mathematical concept."*(Muller, Buteau, Ralph, Mgombelo, in press, p.5)See Original MICA Student Exploratory and Learning Objects
