Biography

Dr. Luxizi Zhang, majoring in Mathematics Education, is a researcher who studies mathematics teachers’ work from the perspective of variation. Her recent focus is on the art of teaching mathematics through variation, which contributes to further studying teachers’ professional development. Taking profit of variation, teachers’ task design, teachers’ collective work, and teacher education can be further studied. Her research findings can be brought to support teachers’ classroom practice.

PhD dissertation

From potential to practical variations in the teaching of functions: contrasting Chinese and French cases in two upper secondary schools

Thesis defended on September 15, 2022, in front of the jury composed of: Pr. Jiansheng Bao (Shanghai), Pr. Ghislaine Gueudet (Paris), Pr. Christian Mercat (Lyon), Pr. Sophie Soury-Lavergne (Lyon), Pr. Luc Trouche (Lyon), Pr. Jianpan Wang (Shanghai), and Pr. Binyan Xu (Shanghai), 

Teaching mathematics through variation appears an important topic as soon as we study task design, many teachers teaching consciously or unconsciously in varying these tasks. This thesis is situated in between China and France, crossing two traditions and cultural contexts, aiming to think fruitful interactions between them and improve the effectiveness of mathematics teaching by understanding the role and evolution of teaching through variation. 

Variation appears in two traditions of research in mathematics education, BIANSHI jiaoxue (Gu et al., 2004) in China and theory of didactical situations (Brousseau, 2002) in France. We propose a preliminary model of “teaching mathematics through variation” by combining these two theoretical approaches with the Documentational Approach to Didactics (Trouche, Gueudet & Pepin, 2020). Our preliminary model distinguishes potential variation, actual variation and practical variation. 

The thesis aims at improving this model from a case study in France and in China, focusing on the topic of function (grade 10). In this perspective, an analytical framework is built, and the concept of variation path is proposed. The thesis opens new perspectives for the enrichment of teachers' resource systems, for teacher professional development, and for the modeling of teachers' work.
