Brief Description of the Talk on 19.02.2022

In this talk, the speaker will share some theoretical ideas and research informed principles about teaching and learning mathematics in different forms of technology-rich settings: 3D printing, touchscreen apps for learning numbers, and dynamic geometry environments (e.g. Geogebra & Desmos), and block-based programming. Drawing on her own experience of teaching with these technologies and researching their use in mathematics classrooms, she will discuss pedagogical suggestions and implications for transforming mathematics education from being characterized as linear, abstract, and paper-and-pencil dominant to multimodal, hands-on, and technological. Specifically, the talk will cover: (1) technologies for embodied mathematics learning, (2) technologies for mediating mathematics thinking, (3) and technologies for constructionist mathematical problem solving.

Recording of the talk by Dr. Oi-Lam Ng.

Speaker and Bio:

Dr. Oi-Lam Ng began her career as a high-school Mathematics teacher in Vancouver, Canada upon completing a BA in Mathematics (First Class Honours) and BEd in Secondary Mathematics Education at the The University of British Columbia. Her passion towards mathematics education continued to motivate her to further her studies in this area. After obtaining her MEd in Curriculum and Instruction at The University of British Columbia, she earned a PhD in Mathematics Education at Simon Fraser University in 2016 and later served briefly as a SSHRC post-doctoral fellow at University of Calgary. Currently, she serves as an Assistant Professor in the Department of Curriculum and Instruction at The Chinese University of Hong Kong. Since 2018, she has been serving as Deputy Programme Coordinator for the Bachelor of Education in Mathematics and Mathematics Education (BMED) Programme.

The speaker will share some current ideas in mathematics education related to teaching and learning mathematics popular in the USA. These ideas are based on research-informed principles and theoretical concepts that helped to develop student-centered teaching and learning. In this talk, the speaker will discuss pedagogical strategies based on research theories such as Constructivism and Sociocultural theory, trying to answer “how do students learn? and “How do we reach out to all students?" particularly focusing on elementary and secondary education and sharing activities that can implement these concepts in classrooms.

Recording of the talk by Prof. Rajee Amarasinghe. 

Speaker and Bio:
Dr. Amarasinghe’s areas of expertise include using technology in mathematics teaching and learning; understanding students’ attitudes toward and beliefs about mathematics; and using interdisciplinary tools in teaching math.

In August 2018, Amarasinghe was awarded a 2018-19 Faculty Innovation and Leadership Award by the CSU Chancellor’s Office. The award recognizes faculty who are implementing innovative practices and who’ve demonstrated leadership in improving student success at a CSU campus. Amarasinghe was nominated by CSU Bakersfield president Dr. Lynnette Zelezny (then provost of Fresno State), who said of his work, “Dr. Amarasinghe has proven unfailingly that he can meet the most pressing challenges with creative solutions.” The professor also received the Provost’s Award for Innovation at Fresno State in 2017-18.

Colleagues have called Amarasinghe “a transformative national leader and scholar” and a creative leader, particularly for his work in designing a new math curriculum that balanced students’ needs, Chancellor’s Office policy and other limitations.

For his part, the Sri Lanka native is eager to share the credit. “I am lucky to have a very energetic and supportive group of colleagues who are working on many initiatives, including a lot of outreach activities to reach our future generation of mathematicians.”

Amarasinghe earned two master’s degrees at Purdue University before getting his doctorate in mathematics education at Indiana University. He arrived at Fresno State in 2000 and to date has received more than $13 million in grant funding. ​

Topic: Tacit mathematical knowledge in teaching: Perspectives and examples

Is there a need for advanced mathematics studies in the professional education and development of school mathematics teachers? While teacher certification requires university-level coursework, teachers often see little value in these courses for their school teaching. The speaker will discuss several perspectives on the “usefulness of knowledge" and share several research results on knowledge use in instructional situations.

Recording of the talk by Prof. Rina Zazkis.

Speaker and Bio:

Rina Zazkis is a Professor of Mathematics Education in the Faculty of Education and an associate member in the Department of Mathematics at the Simon Fraser University, Canada. Her research focuses on tertiary mathematics education, with a particular attention to the development of teachers’ knowledge. She holds an appointment of Tier 1 Canada Research Chair, a prestigious recognition of excellence in research and research training.
