The Internal Assessment (IA) in IB Math is a crucial component of the course, allowing you to explore a mathematical topic of your choice in depth. A well-structured IA not only showcases your understanding and application of mathematical concepts but also makes your work more coherent and compelling. Here’s a guide to help you structure your IB Math IA effectively.

### 1. Introduction

**Purpose:**

- Introduce your topic and explain why you chose it.
- State the aim of your investigation and what you hope to achieve.

**Key Elements:**

**Engaging Opening:**Start with a hook that captures the reader’s interest. This could be an intriguing question, a surprising fact, or a real-world application of your topic.**Context and Background:**Provide any necessary background information to help the reader understand the context of your investigation.**Research Question:**Clearly state your research question or hypothesis.**Objectives:**Outline the objectives of your IA and what you intend to explore.

**Example:** The relationship between music and mathematics has fascinated scholars for centuries. In this IA, I aim to explore how mathematical principles can be applied to understand musical scales and harmonies. Specifically, I will investigate the frequencies of different musical notes and their mathematical ratios to uncover patterns that govern musical harmony.

### 2. Rationale

**Purpose:**

- Explain the significance of your topic.
- Justify why it is worth investigating.

**Key Elements:**

**Personal Interest:**Describe your personal interest in the topic and why it appeals to you.**Mathematical Relevance:**Explain the mathematical significance and how it relates to the IB Math curriculum.**Real-World Applications:**Highlight any practical applications of your topic.

**Example:** Music has always been a passion of mine, and I have been curious about the underlying mathematical structures that create harmony. Understanding these relationships can enhance both musical composition and appreciation. Moreover, this investigation ties into the IB Math curriculum by applying algebra, trigonometry, and calculus concepts to a real-world context.

### 3. Methodology

**Purpose:**

- Describe the methods and procedures you will use to conduct your investigation.

**Key Elements:**

**Data Collection:**Explain how you will gather any necessary data. This could include experiments, surveys, or secondary data sources.**Mathematical Techniques:**Outline the mathematical methods and techniques you will use to analyze the data.**Step-by-Step Process:**Provide a detailed, step-by-step explanation of your approach.

**Example:** To explore the mathematical relationships in music, I will analyze the frequencies of notes in different musical scales. I will use a frequency analyzer to gather data on note frequencies. Using algebraic and trigonometric methods, I will calculate the ratios between these frequencies and examine their patterns. Additionally, I will apply calculus to model sound waves and their harmonics.

### 4. Analysis

**Purpose:**

- Present and analyze your findings.

**Key Elements:**

**Data Presentation:**Use tables, graphs, and charts to present your data clearly.**Mathematical Analysis:**Apply the mathematical techniques outlined in your methodology to analyze the data.**Interpretation:**Interpret the results and discuss what they mean in the context of your research question.

**Example:** The frequency analysis of the C major scale revealed that the ratio between consecutive notes approximates the 12th root of 2. This finding aligns with the mathematical theory of equal temperament tuning, which divides an octave into 12 equal parts. Graphical representations of these frequencies illustrate a consistent pattern, supporting the hypothesis that mathematical ratios underlie musical harmony.

### 5. Conclusion

**Purpose:**

- Summarize your findings and their implications.

**Key Elements:**

**Summary of Findings:**Recap the main findings of your investigation.**Implications:**Discuss the broader implications of your results.**Limitations and Further Research:**Acknowledge any limitations of your study and suggest areas for further research.

**Example:** This investigation has demonstrated the profound connection between mathematics and music, particularly in the context of frequency ratios in musical scales. The consistent patterns observed support the hypothesis that mathematical principles govern musical harmony. However, further research could explore more complex musical structures and different tuning systems to deepen our understanding.

### 6. Reflection

**Purpose:**

- Reflect on the process and what you have learned.

**Key Elements:**

**Personal Growth:**Discuss how the IA has contributed to your personal and academic growth.**Challenges and Overcoming Them:**Reflect on any challenges you faced and how you addressed them.**Skills Development:**Highlight any skills you developed or enhanced during the investigation.

**Example:** Conducting this IA has deepened my appreciation for both mathematics and music. The process of collecting and analyzing data presented challenges, particularly in understanding the mathematical complexities of sound waves. However, overcoming these obstacles has strengthened my problem-solving skills and my ability to apply mathematical concepts to real-world scenarios.

### 7. References

**Purpose:**

- Provide a list of all the sources you used in your IA.

**Key Elements:**

**Proper Formatting:**Use a consistent citation style (e.g., APA, MLA) to format your references.**Comprehensive List:**Include all books, articles, websites, and other sources you consulted.

**Example:** Smith, J. (2010). The Mathematics of Music. Journal of Mathematical Music, 12(3), 45-67. Johnson, L. (2015). Frequency Analysis of Musical Scales. Music and Mathematics, 8(2), 89-102.
