In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.

In this interactive learning activity, learners explore factors that contribute to the aging process. Learners calculate their age based on biological, psychological, and social experiences. Further reflection allows the learner to consider options and assess issues that impact the aging process.

In this learning activity, learners review the value of health and wellness as it relates to exercise, nutrition, intimacy, and spirituality. Examples of each are identified, and learners are given the opportunity to reflect on how these examples are associated with health concerns in older adults.

In this module, we'll be introducing you to SIPOC, a powerful tool that can help you improve your business processes. It's a high-level process mapping tool that helps you identify the key components of a process and how they relate to each other. SIPOC diagrams are often used in Six Sigma and Lean methodologies, but they can be useful for any process improvement initiative. We’ll explain the key SIPOC components and demonstrate how to build one. Then, we’ll walk through a few scenarios and let you build your own.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

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.

Learners examine how metal detectors function. This object includes animation and sound.

In this animated learning object, learners view how the fats that people eat are digested and absorbed.

In this interactive object, learners read about the occupations that are most at risk for bloodborne pathogen exposure. They also read about the most common pathogens and how they are transmitted. This learning object is based on information from the U.S. Occupational Safety and Health Administration.

In this learning activity you'll discover how to evaluate a problem statement using both the MEA and the IP Techniques.

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

In this interactive lesson, learners read and hear instructions for sending an e-mail. Steps are given for composing an e-mail message and for sending it. Students have an opportunity to write their own messages. A quiz follows the instruction.

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.

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 interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates

In this learning activity you'll explore how computers connected on a network use Ethernet technology.

Students examine how voting rates are determined and how those rates change depending upon the population being studied. A brief quiz completes the activity.
