In this learning activity you'll evaluate the Sine, Cosine, and Tangent ratios of a right triangle.

Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.

At the end of this lesson you will be able to

- Explain what biosecurity means.

- Describe why biosecurity is important.

- Identify what kinds of disease agents we try to prevent or control with biosecurity.

- Demonstrate disease agent-host-environmental interactions that result in disease.

Learn more about debugging including: what it is, why we use it, and what it looks like in action.

In this interactive object, learners simplify ratios and solve problems using proportions. All terms are defined.

In this learning activity you'll discover what the .NET Framework is, what problems it solves, and how it came to be.

The learner reads about the kinds of questions that are most effective to use on student questionnaires evaluating instruction. Generic evaluations are less helpful than evaluations focused on the specific types of instruction and learning expected in a content area. Sample questions are provided.

Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.

Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.

In this activity, the learner will understand what denormalization is and when it's an appropriate strategy.

In this screencast, students demonstrate an understanding of summary writing by reading step-by-step instructions and then summarizing short paragraphs. Examples of summaries that are poorly written, as well as those that are written well, are included.

In this learning activity, we’ll learn what an algorithm is.

In this learning activity we will learn what access modifiers are and how they are used in C#.

This is a learning object describing what a learning object actually is. This will take us through the definition of a learning object and break down each segment to help clarify the mystery of this wonderful online tool for teaching and learning.

In this learning activity, you will learn what supply chain management is, four main links that make up the supply chain, and explore examples of how effective supply chain management works.

In this learning activity you'll enter your wage information and learn what a day, an hour, and a minute of their time costs an employer.

In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.

Learners distinguish between competencies that are effective and robust, and those that are ineffective and weak. The learning object is designed for faculty who are writing or revising courses. It contains audio.

Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.

In this learning activity you'll review sample problems and practice simplifying ratios.
