Innovative Practice of Cultural Contextualization Approach in Thailand Primary Mathematics Classroom

Kanchana 【Thailand】

Abstract:

This paper addresses the lack of interest in mathematics learning and the abstraction of concept understanding among primary school students in Thailand. It proposes the “Culturalualization Approach” (CCA), which reconstructs mathematical teaching scenarios through local cultural elements. In combination with three years of teaching practice, innovative cases such as “Geometricsteries in Thai Architecture” and “Currency Calculation in Water Market” are designed for measurement, geometry, and four-arithmetic operations. The practice shows that this increases students' class participation by 42%, and the qualified rate of mathematics application ability test is increased by 35%, which effectively promotes the collaborative development of cultural and mathematical thinking.

1. Introduction: The Realistic Demand Innovative Teaching

The “2025 Basic Education Curriculum” of the Thai Ministry of Education clearly proposes that “mathematics education should be rooted in local culture and practical abilities.” As a front-line teacher, the author finds that traditional teaching has two major pain points:

Abstract symbols are detached from life experience.

For example,fraction comparison" relies on the cake model, but Thai students are more familiar with the division method of Khao Niao (steamed rice with coconut milk). Teaching methods this cultural context can better resonate with students and help them better understand and apply mathematical concepts. In addition, by introducing more examples closely related to daily life, such as currency in market transactions and time calculation in traditional festivals, students' interest and understanding of mathematics can be further enhanced.

Standardized exercises suppress cultural expression. Cases in international textbooks are based on Western contexts (such as sharing pizza), and students find it difficult to establish an emotional connection. This single cultural background not only limits students' horizons but may also cause conflicts and misunderstandings, affecting learning outcomes. Therefore, the Cultural Contextualization Approach (CCA) came into being, aiming to enhance students' interest and understanding in learning integrating diverse cultural elements.

The core framework of the Cultural Contextualization Approach (CCA) is as follows:

1.1 Cultural Carrier (Temple/MarketFestival): Select representative cultural elements as the teaching background, such as using the customs of the Spring Festival to explain probability problems in mathematics, or introducing geometric concepts through the geometric of temple architecture. These cultural carriers not only enrich classroom content but also stimulate students' curiosity and sense of participation.

1.2 Decomposition of Mathematical Problems (Geometry/culation/Statistics): Decompose complex mathematical problems into small problems that can be operated in specific cultural contexts. For example, in the market, basic addition, subtraction, multiplication, and operations can be explained through the scenario of buying and selling goods; during festivals, lantern numbers can be used for statistical analysis. This decomposition method makes abstract mathematical concepts concrete, vivid and easy to understand and master.

1.3.Practice Tasks Driven by Culture: Design practical tasks related to cultural contexts to encourage students to engage in hands-on and real-world applications. For example, have students design a small temple fair event, including booth layout, product pricing, and sales strategies, to apply their acquired mathematical knowledgeively. Such practical tasks not only reinforce students' theoretical knowledge but also foster their creativity and teamwork skills.

Through the Cultural Context Approach (CCA), students can not better understand and master mathematical knowledge but also enhance their cross-cultural communication abilities and global perspectives under the influence of multiculturalism.

2.Innovative Practical Case

2.1Cultural Teaching Aids Development: From Abstract Symbols to Cultural Concrete

Case 1: Geometric Secrets in Thai Architecture (Grade 4 " of Polygons")

Teaching Aid Design:

Use teakwood strips to mosaic the five-tier base of Wat Chiang Luang Temple in Chiang M (composite of trapezoids and rectangles)

Cut out the symmetrical axis of the Khon mask with banana leaves (explore axisymmetric figures)

Comparison of effects of cultural teaching aids and traditional teaching aids

Teaching Reflection:

Students spontaneously measured the size of the family's small Buddha shrine to the amount of paint needed, verifying that knowledge transfer requires cultural identity as a foundation. Through this practical activity, students not only reinforced their measurement and calculation skills in mathematics but also a profound understanding of the importance of cultural context in the application of knowledge. The process of measuring the size of the small Buddha shrine, an item of special significance in the home and calculating the amount of paint needed, allowed students to experience the integration of traditional culture and modern education in actual practice. This sense of cultural identity stimulated students' interest in learning enhanced their ability to apply the knowledge they had learned in practice. Furthermore, through such activities, teachers can better understand the students' family environment and cultural background, thus providing more targeted in the teaching process and promoting the overall development of students.

2.2 Interdisciplinary Thematic Activities: The Social Extension of Mathematical Thinking

Case 2:rency Calculation at the Water Market (Talaat Nam) (Grade 3 "Addition and Subtraction of Decimals")

In this activity, students will and apply the addition and subtraction of decimals through a simulated trading scenario at the water market. First, the teacher will introduce the background knowledge of the Thai water market, including history, cultural characteristics, and trading methods. Next, students will be divided into groups to play different roles, such as vendors, customers, and market administrators, using simulated currency to and sell goods.

During the trading process, students need to accurately calculate the price of goods, including unit price, total price, and change, which all involve the addition and of decimals. For example, a student may purchase two items, one priced at 15.75 Thai baht and the other at 8.25 Thaiht, and they need to calculate the total price and pay the corresponding amount. In addition, the market administrators will randomly set some discount or promotional activities, further increasing the complexity and of the calculations.

Through this practical activity, students can not only consolidate their knowledge of decimal addition and subtraction but also cultivate their practical application ability and social skills. Meanwhile, interdisciplinary teaching method helps to stimulate students' interest in learning and enables them to better understand and master mathematical concepts in real situations.

Implementation Process:

A[Roleignment: Stall Owner/Customer/Banker] --> B(Design of Thai Baht Coins: 1/2/5/10 baht)  B --> C[Purchase List: Coconut 5.5 baht/kg, Mango Flower Garland 30.25 baht,icraft 20 baht]  

C --> D{Challenge: Purchase 3 items with a 50 baht budget}  

D> E[Strategy: Give priority to items with lower prices to ensure the total amount does not exceed the budget]  

E --> F[Result:fully bought 1kg of coconuts, 1 mango flower garland, and 1 handicraft, with 4.25 baht remaining

Generative Learning:

Students discover that the 1/4 baht coin has been taken out of circulation triggering a debate on "Decimal Precision and Real Currency," naturally permeating financial literacy. This phenomenon not only makes students aware of the dynamic changes in the monetary system but also them to think about the application and limitations of decimal precision in actual transactions. For instance, in daily shopping, merchants usually do not accept 1/4 baht coins, which consumers to round up or make change, affecting the precision of the transaction. Moreover, such discussions can be extended to the differences in fractional currency units in different countries and regions, such cents in the United States and Euro cents in Europe, further enriching students' financial knowledge. Through these real-life cases, students can better understand the complexity and practicality the monetary system, cultivating their economic decision-making skills.

2.3 Statistical Practices in Traditional Festivals (Grade 5 "Data Organization")

Case : Research on Water Consumption during Songkran Festival

Data Source

Home water meter readings (Recorded for three consecutive days, including readings at three times a day: morning noon, and evening, to ensure data accuracy)

Interviews on the amount of water used for bathing the Buddha statue in temples (Through in-depth communication with temple staff understand the specific amount of water used for bathing the Buddha statue during each Songkran Festival and collect water usage data from the past five years for comparative analysis)

During the Songran Festival, water consumption in households usually increases significantly. By recording and analyzing detailed water meter readings for three consecutive days, one can clearly see the trend of water usage changes. For, on the first day, water usage may increase as people start preparing for the celebration activities; on the second and third days, water usage may reach its peak as the celebration activities.

In addition, temples, as one of the important venues for the Songkran Festival, are also an important research object for water usage. Through interviews with temple staff, learned that during each Songkran Festival, temples use a large amount of water for the bathing ritual of the Buddha statue. This water usage includes not only the water directly used bathing the Buddha statue but also the water for cleaning the temple, decoration, and providing drinking water for believers who come to attend the activities. By comparing and analyzing the water usage data the past five years, we can discover the trend of water usage changes and explore possible reasons, such as the increase in the number of participants, the impact of climatic conditions,.

3. Key Strategies for Teaching Implementation

3.1 Three Principles for Situation Creation

Cultural Authent:

Avoid symbolic appropriation (such as simply changing Arabic numerals to Thai script), and delve into the cultural roots of mathematical thinking:

Topological structures in Thai → graphical movement

Proportional relationships in traditional prescriptions → fractional operations

Specifically, the intricate patterns and structures in Thai weaving can serve as vivid examples to introduce the concept topology. By analyzing these weaving patterns, students can not only understand the movement and transformation of graphics but also appreciate the application of mathematics in real life. For example, teachers can guide to explore the basic transformations of translation, rotation, and reflection by showing how different weaving methods affect the shape and symmetry of the final pattern.

Moreover, the common ratio problems of in traditional Thai prescriptions provide rich materials for fractional operations. The proportions in prescriptions often involve complex fractional calculations, offering students a real-life context to practice and reinforce their mathematical skills For instance, teachers can design an activity where students adjust the amount of herbs based on the prescription's proportions, thus mastering operations such as addition, subtraction, multiplication, division and simplification of fractions. In this way, students can not only better understand the practical significance of fractions but also cultivate their ability to solve real-world problems.

Cognitive H:

Concrete operation (collage of temple models): By physically assembling temple models, students can intuitively understand architectural structures and cultural backgrounds. This hands-on practice not enhances their spatial perception but also promotes a deeper understanding of history and culture.

Semi-abstract expression (design of market ledger): In the process of designing a market led, students need to connect specific items with monetary values and perform simple addition and subtraction calculations. This stage helps them transition from concrete physical operations to symbolic expressions, cultivating basic mathematical and economic awareness.

Abstract reasoning (forecasting holiday data): Finally, by predicting holiday data, students need to apply logical reasoning and data analysis skills, combining historical data and trends make reasonable predictions. This process not only exercises their abstract thinking abilities but also enhances their problem-solving skills in complex situations.

Diverse Evaluation:

Adopt a growth to record:

Math diary (cultural associations in problem-solving processes): Record how students incorporate cultural backgrounds and personal experiences into their problem-solving strategies when solving math problems For example, by analyzing the problem-solving methods of ancient Chinese mathematicians and combining modern mathematical theories, explore new problem-solving paths

Community Service Project Report: A detailed description of the entire process of students participating in community service projects, including project planning,, and summary. For example, organize a community environmental protection activity, from pre-activity research and publicity to actual operation and final effect evaluation, fully demonstrating the students' sense of responsibility and teamwork ability.

Traditional Game Improvement Plan (such as probability analysis of Saba): In-depth research on the rules and strategies of traditional games, use mathematical to carry out probability analysis, and propose innovative improvement plans. For example, by calculating the probability of different moves in Saba, optimize the game balance and increase the fun and of the game.

3.2 Teacher Role Transformation

From "Knowledge Transmitter" to Cultural Mediator:

"When students use the golden ratio to analyze the pillars of the Yufo Temple, I no longer directly judge right or wrong, but ask in depth:

'Why did the ancient craftsmen choose this ratio? Do you think's related to Buddhist philosophy?'

This prompts them to think about the cultural logic behind the mathematics.

Through such guidance, students not only understand the mathematical principles of golden ratio but also explore its application in architectural aesthetics in depth. This interdisciplinary teaching method enables students to combine mathematical knowledge with historical and cultural background, cultivating their comprehensive thinking ability

In addition, I also encourage students to consult relevant literature to understand the changes in architectural styles in different historical periods and think about the social, cultural, and technological factors behind these. For example, they will discover that different proportions and geometric shapes have different symbolic meanings in architecture of different periods, and these meanings are often closely related to the social values and beliefs of the time.

Through this method, students can not only master specific mathematical knowledge but also cultivate critical thinking and interdisciplinary research capabilities, laying a solid foundation for future learning work."

4. Effectiveness and Reflection

Quantitative Comparison (Experimental class control class in the 2023-2024 academic year)）

Deep Reflection:

Cultural Boundary Issues: The proposal by southern Muslim students to "replaceagoda models with mosque arches" suggests the need for dynamic adjustments to cultural carriers. This proposal reflects the differences in educational needs across different cultural backgrounds and emphasizes the need for flexibility inclusiveness in educational content and forms in a multicultural environment. By introducing more diverse cultural elements, students can be encouraged to understand and respect each other, reduce cultural conflicts and enhance social cohesion.

Home-School Collaboration Challenges: The anxiety of elderly parents about modern mathematics needs to be addressed through "Market Math Parent Workshops." workshops can not only help parents understand the teaching methods of modern mathematics but also provide opportunities for practical application, enabling them to apply this knowledge in their daily lives. Moreover, through interaction communication, parents can share their experiences and concerns, forming a support network to reduce their anxiety and improve the quality of family education.

5. Conclusion

The cultural contextual method transforms mathematics from an "abstract symbolic system" into a cultural practice tool, enabling Thai students to strengthen their cultural confidence and innovative thinking while mastering core concepts. By integrating problems into local historical stories, traditional festivals, and daily life scenarios, students can not only better understand the application value of mathematics but also experience the charm of culture in the problem-olving process. For example, when learning geometric shapes, patterns from Thai folk art can be used for teaching, allowing students to appreciate the beauty of art while mastering geometric knowledge.Subsequent research will explore the cultural mathematical elements of neighboring countries such as Cambodia and Laos to construct a teaching resource database for elementary mathematics in the Lancang River Basin. research aims to enrich the content of mathematics education through cross-cultural exchanges and promote educational cooperation and development within the region. For instance, Cambodian architectural styles and Laotian traditional can be collected as mathematical teaching materials to help students feel the uniqueness of different cultures not only when applying mathematical knowledge to solve practical problems but also when appreciating the beauty of different cultures In this way, not only can students' mathematical literacy be improved, but also their understanding and respect for multiculturalism can be enhanced, cultivating a global perspective and cross- communication skills.
