## [Main Floor] Introduction to the Study on Activating Graphic Thinking Through Vivid Classroom Discourse

This study focuses on mathematics classroom discourse, using systemic functional linguistics as a perspective to explore how teachers use vivid informal language to help students establish cognitive connections between graphics and quantitative changes, aiming to provide a new perspective for mathematics education practice. The core of the study concerns the role of classroom discourse in activating students' graphic thinking, and reveals key discourse strategies and their teaching significance through the analysis of real classroom interactions.

## Research Background: The Core Position of Graphic Thinking and Cognitive Gaps

In mathematics education, graphic thinking is a core ability for understanding functions, rates of change, and covariation relationships. Students need to extract dynamic information from static graphics, but many students face cognitive difficulties in transitioning from visual perception to mathematical reasoning. Traditional teaching focuses on symbolic operations and formal definitions, ignoring the bridge between graphic representation and intuitive understanding; in recent years, researchers have begun to focus on the role of classroom discourse in building this bridge, especially how teachers guide students to understand the mathematical structure behind graphics through language.

## Research Perspective: Discourse Analysis Framework of Systemic Functional Linguistics

This study uses Systemic Functional Linguistics (SFL) as an analytical framework. This theory focuses on meaning construction of language in social contexts and emphasizes three metafunctions: ideational function (expressing content), interpersonal function (establishing relationships), and textual function (organizing information). In the context of mathematics classrooms, SFL provides a refined tool for analyzing teachers' discourse, allowing attention to vocabulary choices, sentence structure organization, and language strategies that highlight or downplay mathematical features, revealing the cognitive guidance mechanism in teaching interactions.

## Research Findings: Key Strategies of Vivid Informal Discourse

Through the analysis of real classroom interactions, three key strategies of vivid informal discourse were identified: 1. Concrete description: Using sensory vocabulary and dynamic verbs (e.g., "climb steeply") to transform abstract graphic features into perceivable images; 2. Foregrounding and backgrounding: Adjusting students' attention focus to highlight specific graphic features (e.g., inflection points, extreme points); 3. Linguistic construction of covariation relationships: Helping students understand the laws of simultaneous changes between variables, so that the dynamic changes encoded in the shape of graphics can be "tracked".

## Teaching Significance: Guiding Value for Mathematics Teaching Practice

The research findings have direct guiding significance for teaching practice: 1. Challenging the stereotype that "mathematical language must be strictly formal"—vivid informal discourse has important cognitive functions; 2. Discourse choice is a cognitive scaffold—teachers can consciously design classroom discourse to optimize learning support; 3. Discourse analysis can serve as a framework for teachers to reflect on their teaching practice, helping to improve language strategies.

## Research Limitations and Future Exploration Directions

This study has limitations: The generalizability of the conclusions needs to be verified in a wider range of teaching contexts (student responses may vary across different cultures and academic levels); the causal relationship between discourse and cognitive development needs to be established through more rigorous experiments. Future research can explore the cultivation of graphic thinking in technical environments, such as the synergistic effect of teachers' discourse with dynamic geometry software and visualization tools.

## Conclusion: Discourse as a Tool for Cognitive Construction

The teacher-student interaction in mathematics classrooms contains rich educational significance. Teachers' discourse is not only a medium for information transmission but also a tool for cognitive construction. Through the perspective of systemic functional linguistics, we can deeply understand how teaching discourse shapes students' mathematical thinking, providing a theoretical basis for improving mathematics education practice.
