Sang Moo Lee

Also professionally known as Sang Lee.

Mathematics & computer science educator and mathematics education researcher specializing in critical thinking in mathematics classrooms, inquiry-based learning, equity-oriented pedagogy, assessment design, and technology-enhanced instruction.

Toronto, Ontario PhD (ABD), OISE (U of T) Grades 7–12 Math & CS Post-secondary instructor (blended/online)

Over 10 years of teaching experience across Grades 7–12 mathematics and computer science, plus post-secondary instructional experience in blended and online learning environments. Recognized for innovative STEM pedagogy (Prime Minister’s STEM Teaching Certificate of Achievement; Rosenthal Prize Finalist).

Teaching

I use inquiry-based instruction and differentiated entry points, grounded in Ontario curriculum and assessment for/as/of learning, with UDL principles and culturally responsive tasks.

  • Secondary STEM Educator - The Linden School (Grades 7-12) 2016-Present
    Wikipedia

    Designed and taught 60+ STEM courses (e.g., MHF4U, MCV4U, MCR3U, MPM2D, MTH1W, ICS2O/ICS3U/ICS4U; Grades 7–8 math). Integrated Desmos, GeoGebra, Python, and JavaScript through interdisciplinary, real-world projects and ministry-aligned assessment.

Classroom Innovation Highlights

Selected projects demonstrating interdisciplinary design, authentic problem-solving, and student-facing impact.

  • Romans in Cyberspace Interdisciplinary game development

    Students combined storytelling, history, and computer science to build an educational game, strengthening design thinking, collaboration, and computational creativity.

  • Student-built scheduling / timetabling prototype Full-stack problem-solving

    Senior students developed an app prototype to address a real school scheduling need, working through iterative design, data structures, and user feedback.

  • Economics & justice inquiry culminating in a public fair Math as civic participation

    Students investigated contemporary economic issues (e.g., inflation, tariffs, inequality) using mathematical tools and shared findings with families/community members through a student-led exhibition.

  • AI-enabled projects in CS classrooms Emerging tech + student agency

    Students explored AI concepts through hands-on builds (e.g., object detection games), connecting technical skill to critical reflection about technology’s role in society.

Research / Scholarship

Mathematics education research specializing in the development of critical thinking in mathematics classrooms, bridging classroom practice and research.

  • PhD (ABD) - University of Toronto (OISE) 2020-Ongoing

    Thesis: Conceptualizing Critical Thinking in Math Classrooms.

  • Methods & strengths Qualitative + classroom design

    Qualitative case study methodology; semi-structured interviewing and thematic coding; ethics protocol development; classroom design and assessment frameworks supporting metacognition, discourse, and conceptual reasoning.

Research Agenda

My scholarship focuses on how critical thinking is conceptualized, taught, and evidenced in mathematics classrooms. Especially in contexts shaped by emerging technologies and shifting social/economic realities.

  • Theme 1: Conceptualizing critical thinking in mathematics Theory + classroom meaning-making

    I examine how teachers interpret “critical thinking” in mathematics, and what counts as evidence of critical thinking in classroom discourse, tasks, and assessment.

  • Theme 2: Assessment & pedagogy for reasoning, discourse, and metacognition Design + feedback

    I design and refine learning environments that promote explanation, justification, critique, and reflection—using assessment for/as/of learning, UDL, and structured classroom talk routines.

  • Theme 3: AI, real-world contexts, and justice-oriented mathematical inquiry Contemporary relevance

    I explore how AI and real-world economic events can be used as catalysts for mathematical inquiry, helping students connect quantitative reasoning to ethical and civic questions.

  • Current study Qualitative interviews + thematic coding

    Ongoing doctoral research using semi-structured interviews and thematic analysis to understand how Ontario mathematics teachers conceptualize critical thinking and enact it in practice.

Post-secondary & Other Experience
