In this learning activity, you’ll identify information hackers use to gain access to a company, explain different types of social engineering attacks, and recognize different solutions to avoid these attacks.

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.

Explore what DDoS attacks are, the methods used to carry them out, and how to prevent them.

In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

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

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

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.

In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.

Learners examine the information on a title block and answer questions about that information in an interactive quiz.

In this interactive object, learners examine the structural-functional, social-conflict, and symbolic interaction analyses of socialization. A mind map and quiz questions are included.

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.

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.

The learner will represent very large and very small numbers in engineering notation.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

Learners view examples of waste in an office environment and are asked to consider what they can do to eliminate or reduce waste in their own workplace.

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. A quiz completes the activity.
