Strategies for Efficiently Organizing IB Mathematics Internal Assessment (IA)
In the realm of mathematics, few connections are as fascinating as the one between numbers and music. This article is a step-by-step guide on conducting an Internal Assessment (IA) in IB Mathematics, focusing on the exploration of the relationship between mathematics and music, particularly in the context of frequency ratios in musical scales.
## 1. Introduction
The topic of this investigation was chosen to delve into the intriguing world where mathematics and music intersect. The relevance of this subject lies in its ability to illustrate the beauty and complexity of both disciplines, while also demonstrating the practical applications of mathematical concepts. The personal interest in this topic stemmed from a curiosity about the hidden patterns that underlie musical harmony.
The aim of this exploration was to summarise the connection between mathematics and music, with a specific focus on the frequency ratios in musical scales.
## 2. Development of the Investigation
The investigation began by introducing the necessary concepts, definitions, and formulas related to sound waves, frequencies, and musical scales. The approach was broken down into logical steps, with each step clearly illustrated and justified. Graphical representations were used extensively to present data and support the analysis.
## 3. Results and Analysis
The results of the investigation aligned with the mathematical theory of equal temperament tuning. Graphical representations of these frequencies showed a consistent pattern, supporting the hypothesis that mathematical ratios underlie musical harmony. The main finding was that the ratio between consecutive notes in the C major scale approximates the 12th root of 2.
## 4. Conclusion
The conclusion of the investigation recapped the main points and results, reflecting on what was learned throughout the process. The findings answered the initial question, providing a deeper understanding of the relationship between mathematics and music. Suggestions for future extension included exploring more complex musical structures and different tuning systems.
## 5. References and Bibliography
The Internal Assessment used a consistent citation style, including all books, articles, websites, and other sources consulted. The references were listed in a consistent format, with the APA style commonly used for IB math IAs.
## 6. Appendices (Optional)
Appendices provided supplementary material that would have disrupted the flow of the main report if included directly. This included raw data tables, large calculations, and additional graphs.
## 7. Presentation and Formatting
The IA was organised logically, easy to follow, and well-structured. Appropriate mathematical language, symbols, and terminology were used, with key terms defined where necessary. Graphs, tables, and diagrams were placed within the main body for clarity and coherence.
## 8. Assessment Criteria Overview
The assessment criteria focused on communication, mathematical presentation, personal engagement, reflection, and the use of mathematics. Meeting these criteria will lead to an effective, well-structured IB Mathematics Internal Assessment.
This investigation not only contributed to personal and academic growth but also provided insights into overcoming obstacles, strengthening problem-solving skills, and the ability to apply mathematical concepts to real-world scenarios. The process presented challenges, particularly in understanding the mathematical complexities of sound waves. However, the rewards of uncovering these hidden patterns and connections between mathematics and music made the journey worthwhile.
During the course of this investigation, I discovered a profound connection between mathematics and music, focusing on the exploration of frequency ratios in musical scales. This journey served as an opportunity for both personal and academic development, allowing me toApply learning to real-world scenarios, strengthen problem-solving skills, and gain a deeper understanding of the relationships between these two captivating disciplines in the realm of education-and-self-development and personal-growth.
