Ethno Sense is defined as a culturally mediated cognitive–perceptual capacity through which individuals discern, select, and interpret mathematically salient structures in socially situated practices. The increasing recognition of mathematics as a culturally situated practice has prompted growing interest in integrating cultural contexts into mathematics education. Approaches such as ethnomathematics and Realistic Mathematics Education emphasize the importance of culture and meaningful contexts; however, a critical gap remains in explaining how individuals perceive and recognize mathematical structures within culturally embedded experiences. This entry addresses this gap by introducing Ethno Sense as a novel conceptual construct. Conceptualized as a pre-formal layer of mathematical cognition, it explains how culturally conditioned perception, interpretive schemas, and value systems shape the recognition of mathematical meaning prior to formalization. It proposes a mechanism comprising contextual indexing, schema activation and selection, and value-informed interpretation. These processes operate dynamically to guide engagement with culturally meaningful phenomena and the identification of mathematical relevance. The entry further positions Ethno Sense as an epistemological foundation for Ethno-Realistic Mathematics Education, supporting authentic context selection and progressive mathematization. By foregrounding culturally mediated perception, it shifts attention from problem solving to recognizing situations as mathematically meaningful. This study contributes a unifying theoretical construct linking cultural experience and mathematical cognition, and outlines implications for practice and future research on culturally situated learning. Ultimately it offers a lens for understanding reciprocal relationships between culture and mathematics across educational contexts.
In recent decades, there has been growing recognition that mathematics is not a culturally neutral body of knowledge but rather a human activity deeply embedded in social, historical, and cultural contexts [
1,
2]. This perspective has been strongly advanced through the development of ethnomathematics, which highlights the diverse mathematical practices that emerge within specific cultural groups [
3]. Such practices include counting systems, spatial reasoning, measurement techniques, and patterns found in traditional artifacts [
4,
5], all of which demonstrate that mathematical thinking is shaped by cultural experiences and worldviews.
Parallel to this development, Realistic Mathematics Education (RME) has emphasized the importance of meaningful contexts in supporting students’ mathematical understanding [
6,
7]. RME promotes the idea that learning mathematics should begin with situations that are experientially real to learners, allowing them to engage in progressive mathematization from informal strategies toward formal mathematical concepts [
8]. In many educational settings, particularly in culturally diverse societies such as Indonesia, this principle has encouraged the integration of local cultural contexts—such as traditional games [
9], crafts [
10], and architectural practices [
11]—into mathematics instruction.
The convergence of ethnomathematics and RME has generated integrative approaches such as Ethno-Realistic Mathematics Education (Ethno-RME), which aim to connect students’ cultural knowledge with formal mathematical learning processes [
12,
13]. While this approach holds significant promise, a critical challenge remains that the selection and use of cultural contexts often risk becoming superficial or artificial. In many cases, cultural elements are merely appended to mathematical problems without reflecting the lived experiences, values, and perceptual frameworks of the learners [
14]. Consequently, the intended meaningfulness of context is attenuated, limiting students’ opportunities to engage with mathematics in ways that are experientially and conceptually significant.
Despite the significant contributions of ethnomathematics and RME, a fundamental conceptual gap remains insufficiently addressed. Existing approaches have largely focused on what counts as mathematics in culture, emphasizing the identification and incorporation of cultural practices into mathematics education [
12,
13]. However, comparatively limited attention has been directed toward understanding how mathematics becomes recognizable within culture—that is, how individuals perceive, interpret, and identify mathematically meaningful structures embedded in their everyday sociocultural environments. This gap highlights the need for a theoretical framework that explains the culturally mediated processes underlying the recognition of mathematical meaning.
Furthermore, this challenge also points to a fundamental gap in the existing literature: the lack of a conceptual framework that explains how individuals perceive, interpret, and assign meaning to culturally embedded mathematical phenomena. Although concepts such as sense-making [
15,
16], mathematical sense [
17], and cultural competence [
18] have been widely discussed, they do not fully capture the complex, culturally mediated processes through which learners come to recognize and engage with mathematical structures in everyday life. In particular, insufficient attention has been given to the dynamic interplay among sensory experience, cultural schemas, and socially constructed forms of “common sense” in shaping mathematical understanding.
To address this gap, this entry introduces and develops the concept of Ethno Sense as a theoretical construct in mathematics education. Ethno Sense is conceptualized as a culturally grounded capacity that enables individuals to perceive, select, and interpret mathematically meaningful patterns and relationships within their sociocultural environment. It extends beyond mere knowledge of cultural artifacts by emphasizing the role of sensory perception, cultural scripts, and value systems in guiding mathematical sense-making [
15,
19].
By situating Ethno Sense within interdisciplinary perspectives, including anthropology of the senses [
20], ethnolinguistics [
21], ethnoscience [
22], and ethnomathematics [
4], this study seeks to establish a comprehensive conceptual foundation for understanding the reciprocal relationship between culture and mathematics. Furthermore, Ethno Sense is positioned as a critical mechanism within Ethno-RME, enabling educators to identify and design authentic, culturally resonant learning contexts that foster meaningful and inclusive mathematical engagement.
This entry provides a structured overview of the existing literature on culture, perception, and mathematics education. It aims to conceptualize Ethno Sense and its foundational components, explicate the mechanisms through which it operates in identifying meaningful learning contexts, and examine its implications for the design and implementation of culturally responsive mathematics instruction. The analysis draws primarily on peer-reviewed publications indexed in major international databases, including Scopus, spanning disciplines such as ethnomathematics, RME, Ethno-RME, cultural studies, linguistics, and anthropology. Where relevant, historical and cultural sources are considered insofar as they are critically examined within the scholarly literature. Methodologically, the study is informed by a historical–cultural perspective and employs conceptual and comparative analysis to trace how meanings are constructed, negotiated, and reinterpreted across different cultural contexts.
The remainder of this entry is structured as follows. The next section establishes the theoretical foundations underpinning the development of Ethno Sense by synthesizing perspectives from ethnomathematics, realistic mathematics education, and cultural approaches to perception and cognition. This is followed by a conceptual elaboration of Ethno Sense as a bridging construct between culture and mathematical meaning, including a detailed account of its underlying mechanism. Subsequent sections examine the role of Ethno Sense within Ethno-Realistic Mathematics Education (Ethno-RME), with particular attention to its applications and educational implications in culturally responsive pedagogy. The entry concludes by consolidating its theoretical contributions and outlining the broader significance of Ethno Sense for advancing culturally situated approaches to mathematics education.
Finally, although Ethno Sense is grounded in culturally mediated processes, its underlying mechanism reflects a general human capacity for perceiving, organizing, and interpreting meaningful patterns in experience, suggesting its potential relevance across diverse cultural and educational contexts. In doing so, this study contributes to ongoing efforts to reconceptualize mathematics education as a culturally grounded practice, offering a systematic lens through which the reciprocal relationship between culture and mathematics can be more rigorously understood and meaningfully enacted.
