Academic Programme



The theme of the 43rd PME conference is:

Improving access to the power of mathematics


The overall programme for the conference is now available.

A rough draft detailed programme has also now been made available. At this stage the purpose is for you to check whether your paper appears in the programme or not, rather than to check if the time suits you.

This Excel file is not very easy to read and we are working on a friendlier version. 

NEW: The programme and other conference information for the conference is now available.

Important:  You should look up your submission ID number on ConfTool and then search for that on the schedule as the presentation titles and at times some authors are not currently in the Excel table. It must be the submission ID of the accepted contribution. For example the ID for an OC that was previously an RR will be different. Some co-authors may also not be listed in the Excel file.

Plenary lectures

There will be four plenary addresses from invited speakers, each lasting 60 minutes. The plenary speakers for PME43 are:

Nuria Planas (Spain)

When I began teaching mathematics in secondary schools of Barcelona, I found many learners who did not speak mathematics in the language of instruction and were unfamiliar with the local routines. That early experience continues to influence my choices as a mathematics education researcher. I am most concerned with understanding various aspects of multilingual mathematics teaching and learning, and their relationship with issues of equity. To this end, I work with social and political theories of mathematics thinking and learning, but also sociolinguistics and functional linguistics in the attempt to represent the role of language and language diversity in the production of school mathematics.

Ravi Subramaniam (India)

K. Subramaniam (Ravi) is Professor and Centre Director of the Homi Bhabha Centre for Science Education, Tata Institute of Fundamental Research in Mumbai, India. His main research interests are the design and organization of core areas of the middle grade mathematics curriculum such as fractions, proportional thinking, geometric measurement and algebra, and the specialized knowledge that teachers need to teach effectively at this level. His other interests are the integration of out-of-school knowledge and school learning of mathematics, frameworks for analysis of mathematics teaching and the role of visualization in the learning of science. He has contributed to the work of curriculum and textbook committees and to in-service teacher professional development in India.

Talk title: Representational coherence in instruction as a means of enhancing students' access to mathematics




Peter Liljedahl (Canada)

Dr. Peter Liljedahl is a Professor of Mathematics Education in the Faculty of Education and an associate member in the Department of Mathematics at Simon Fraser University in Vancouver, Canada.

Dr. Liljedahl is the current president of the Canadian Mathematics Education Study Group (CMESG) and International Group for the Psychology of Mathematics Education (PME). He serves on the editorial boards of ESM, JMTE, MTL, FMEJ, MERJ, and CJSMTE and is a senior editor of IJSME. He has authored or co-authored 9 books, 26 book chapters, 27 journal articles, and over 50 conference papers.  Dr. Liljedahl is also a member of the executive of the British Columbia Mathematics Teachers Association (BCAMT) and former co-editor of their flagship journal, Vector. Dr. Liljedahl is the recent recipinet of the Cmolik Prize for enhancement of public education in BC as well as the Margaret Sinclair memorial award for innovation and excellence in mathematics education.

Dr. Liljedahl is a former high school mathematics teacher who has kept his research interest and activities close to the classroom. His research interests are creativity, insight, and discovery in mathematics teaching and learning; the role of the affective domain on the teaching and learning of mathematics; the professional growth of mathematics teachers; mathematical problem solving; numeracy; and engaging student thinking. He consults regularly with schools, school districts, and ministries of education on issues of teaching and learning, assessment, and numeracy.

Panel members


Mercy Kazima (Malawi)

Mercy Kazima is Professor of Mathematics Education at the University of Malawi. Her work includes teaching mathematics and mathematics education to both undergraduate and postgraduate students, and supervising PhD and master students’ research projects. Mercy has vast experience in mathematics education research in the areas of mathematical knowledge for teaching, teaching mathematics in multilingual contexts, and mathematics teacher education. She was president of the Southern Africa Association for Research in Mathematics Science and Technology Education (SAARMSTE) and has contributed to research in mathematics education in the region. Mercy is currently leader of two five-year projects namely: Improving quality and capacity of mathematics teacher education in Malawi (2014-2018) and Strengthening numeracy in early years of primary education through professional development of teachers (2017-2021).

Robyn Jorgensen is Emeritus Professor at the University of Canberra. She has worked in the area of equity and mathematics since commencing her doctoral studies  - a career that has spanned nearly 3 decades. Her work attempts to understand the subtle (and not so subtle) practices through which inequities are constructed particularly for low SES, rural and/or Indigenous learners. More recently her work has centred on the practices in remote Indigenous contexts that have brought about success for remote Indigenous learners. She is the recipient of 15 Australian Research  Councils grants, is widely published, and has been editor of the Mathematics Education Research Journal.  She has also worked with the swim industry and completed a research projects that have had significant international impact on early years swimming; have been translated into a number of languages and was inducted into the Swim Schools Hall of Fame for her scientific contribution to the swim industry.  She has served on numerous panels and boards advising government and industry.  She recently retired from the University of Canberra but continues to work in the capacity as a consultant with UC and private practice.  


Hee-jeong Kim (Korea)

Hee-jeong Kim is an assistant professor of Mathematics Education at Hongik University, Korea. Her current research interests include mathematics teacher change in practice towards developing their professional visions and improving their teaching practice, and how to support teachers to make such changes. She collaborates with several international scholars to study on several core principles and features on mathematics classrooms internationally. She received her PhD at UC Berkeley.
