Study Notes
Introduction
- Models are used in various disciplines (biology, engineering, computer science, psychology, sociology, and marketing).
- Mathematical models can be used to find patterns in life.
- Defining the problem is critical in modeling.
- Assumptions help simplify complex problems by focusing on key variables.
- Defining variables is essential for understanding the problem and forming equations.
- Building a solution involves using appropriate mathematical tools.
- Analysis and assessment involve evaluating results and identifying potential improvements.
- Reporting results involves clearly explaining the model's findings.
Defining the Problem
- Mathematical models answer open-ended questions.
- Problems can be approached in several ways.
Making Assumptions
- Assumptions simplify problems by reducing the number of variables to consider.
- Assumptions are used to make research easier and focus on essential aspects of the problem.
Defining Variables
- Defining variables helps in identifying all factors involved in the equation.
- Understanding the problem is key to defining variables correctly.
- Correct variable definitions are crucial for a good model.
Building a Solution
- Finding the solution involves using the tools and methods in the mathematical toolbox.
- Various mathematical models can be used to solve problems.
- Advanced computer software can be used to solve complex computations.
Analysis and Assessment
- Evaluating the model's theoretical value for practical application is important.
- Improvements to the model based on its evaluation should be noted.
- The model's results are crucial for understanding the context of the problem.
Reporting Results
- Clearly explaining the model is the last step in the process.
- The process and results must be explained in detail for other people to understand.
- The explanation must be free of technical jargon.
Defining Problem (Part 2)
- The United Nations Sustainable Development Goals (SDGs) aim to solve major problems like poverty, hunger, and inequality.
- Improving people's lives is based on 17 interconnected global goals.
- Protecting the environment is a key goal, including having clean water, affordable energy, and addressing climate change.
Make Assumptions (Part 3)
- Population growth in a country is the result of births and immigration exceeding deaths and emigration.
- Birth rate, death rate, immigration, and emigration are factors influencing population growth.
- Factors like healthcare, lifestyle, and economic conditions impact population growth.
Define Variables (Part 4)
- Mathematical model predicts Thailand’s population in 2030.
- Independent variable (x) is time.
- Dependent variable (y) is population.
Build Solutions (Part 5)
- Data on Thailand’s population from 2000 to 2021 is collected.
- A scatter plot is created in Desmos to understand population trends.
- Regression analysis using various functions (quadratic, cubic, exponential, logarithmic) determines the best fit for the data.
Analysis and Assessment (Part 6)
- The model's prediction for Thailand’s population in 2030 is calculated using the chosen function (cubic).
- The prediction is compared with similar predictions for other advanced economies (G7 countries).
- The number of teachers in Thailand in 2030 was predicted using a similar methodology (scatter plot of number of teachers over the 2000-2015 data).
- Also, the obtained result is compared with the average number of teachers per 1000 people in G7 countries.
References
- Various references on mathematical modeling, solutions, and the UN's Sustainable Development Goals are listed.
