EARTH STUDIES
DEMONSTRATION MODULE
World Population

Introduction:

We introduce:

1. The format and methods used to analyze data and solve problems
2. Demonstrate the structured format that is used.
3. Applets, or little programs, that are used with each Study.
4. Applets perform the math operations needed to analyze
data and build mathematical modules.
5. Links are included to explain math terms and methods.
We guide you through a study on population that illustrates the most common methods used in Earth Math Studies and illustrate the use of the applets.First, we outline the general structure for all the Studies.

 

Each Study has three components:
The text provides information about a particular issue and questions;
The Menu has two parts: applets to perform the mathematical operations; and the Topics list has links to explain relevant mathematical topics;
The journal is the place where you record your thoughts, answers, and mathematical solutions.

 

This is the Diné Education Philosophy model of the thought process involved in using mathematical reasoning. You will be asked to use the following outline in structuring your answers to math problems.

They are:
Nitsáhákees (thinking)(time to get out your journals) section provides information about the issue and asks pertinent (important) questions. Then, you express your own ideas regarding the issue.
Nahat'á (planning)(to aquire more information or data) section provides more detailed information, relevant data, or directs you to a website to acquire more information or data.
Iiná (living)(This section uses applets) section asks specific questions which requires mathematical analysis. This leads to a mathematical model. The model should provide answers to questions raised regarding the issue. This section uses the applets.
Sihasin (assurance)(This section asks questions) regarding the reasonableness or validity of your model.

 

The "Applets in the Menu" is the place where you access the applets that perform the mathematics. Here you enter your data or other quantitative information and use the applets to analyze data and construct mathematical models The results should answer the questions involved in the issue.
The journal is the place where you record your answers to questions and include the "explanations of the mathematics" that you used. Your journal "should be written as a file in the word processing package on your computer".
This is the document that you turn in to your instructor.
