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

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 resistance decreases in a parallel circuit as branches are added.

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 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 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.

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

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.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.

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

The learner examines what it means to listen respectively and how to become a better listener.

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

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 animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.

Learners examine how CEC, base saturation, and soil pH work with each other to define plant nutrient availability.

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

In this learning activity, we’ll explore what RESTful services are, how they interact with clients and servers, and finally, understand how it works within an HTTP framework.
