KiteModeler was developed in an effort to foster hands-on, inquiry-based learning in science and math. KiteModeler is a simulator that models the design, trimming, and flight of a kite. The program works in three modes: Design Mode, Trim Mode, or Flight Mode. In the Design Mode (shown below), you pick from five basic types of kite designs. You can then change design variables including the length and width of various sections of the kite. You can also select different materials for each component. When you have a design that you like, you switch to the Trim Mode where you set the length of the bridle string and tail and the location of the knot attaching the bridle to the control line. Based on your inputs, the program computes the center of gravity and pressure, the magnitude of the aerodynamic forces and the weight, and determines the stability of your kite. With a stable kite design, you are ready for Flight Mode. In Flight Mode you set the wind speed and the length of control line. The program then computes the sag of the line caused by the weight of the string and the height and distance that your kite would fly. Using all three modes, you can investigate how a kite flies, and the factors that affect its performance.

In their continued support of climate science education, the Washington State Office of Superintendent of Public Instruction (OSPI) created these sample bundles of Washington State Learning Standards from multiple content areas that teachers could use to center their classroom instruction around climate change and climate science. 

Complete set of mobile friendly Intermediate Algebra sample exams with solutions. In addition, there are links to pdf versions and a sample final exam with answers.

This OER explores the basic organization of the Constellations. It contains both an activity as well as resources for further exploration. It is a product of the OU Academy of the Lynx, developed in conjunction with the Galileo's World Exhibition at the University of Oklahoma.

Videos introducing negative integers and adding and subtracting them.

Accounting is the process of identifying, measuring, recording, and communicating an organization’s economic activities to users. Users need information for decision making. With an emphasis on the corporate form of business organization, this lesson will examine how financial transactions are analyzed and then reported using four financial statements: the income statement, statement of changes in equity, balance sheet, and statement of cash flows. This lesson introduces each statement using an example based on a fictitious corporate organization called Big Dog Carworks Corp.

E-Learning is defined as learning utilizing electronic technologies to access educational curriculum outside of a traditional classroom. This unit will help students to understand e-learning at the University of Belize and the different modalities (Web-Enhanced, Blended, and Online) associated with it. In addition, this unit will address the expectations of e-learners and provide a guide to help students choose the best modality based on their respective learning styles. We will compare the pros and cons of the different modalities (Web-Enhanced, Blended, and Online) accompanied by characteristics and examples best suited to be successful e-learners.

Open Code is a tool for coding and categorizing qualitative data. Open Code 4.0 is a tool to help you index and sort big materials, so it can be searched and re-arranged for further analysis. Open Code was developed to follow the first steps of Grounded Theory but it is now possible to use it for all qualitative methods and it is prepared for Grounded Theory and Qualitative Content analysis. It is useful for sorting and classifying any kind of qualitative information. The software is developed to run on Windows. To run it on a Mac, you have to run a virtual machine or other systems to run pc-software on a mac computer.

How to create a project in Open Code 4. How to import documents to prepare for an analysis. Each project is an database of documents.

An introduction and examples of how to use basic concepts in statistics, used in quantative studies: samples, population, variables, random samples, groups, ranking, measurement levels.

Many GED/ESL students have a lapse in education.  As a result, the concept of fractions is a difficult task to teach to the adult learner. This OER will give the student the basic introduction to the concept of fractions.  Gaining confidence the student can move on to higher level mathematics.

Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers.

Sal introduces the famous and super important Pythagorean theorem! This lesson includes an introduction video followed by examples and practice problems involving finding the hypotenuse, finding a side, finding area of an isosceles triangle, and determining if a triangle is a right triangle. It is followed by a unit on Pythagorean theorem applications.
