This interactive learning object demonstrates how the moisture content is determined for a given sample of soil or aggregate.

In this screencast, you'll distinguish the differences between the content message and the relational message.

In this learning object designed for educators, users review strategies for teaching reading in all classrooms, not just in the reading or language arts classroom. Two pages contain audio.

Learners use this Structured Query Language tutorial to gain an understanding of how a SELECT statement is built. This learning object has audio content.

Learners examine how language can interfere with clear communication. They select examples of ambiguity, assuring expressions, doublespeak euphemisms, jargon, emotive content, false implications, meaningless comparisons, and vagueness. In an interactive exercise, learners identify ways to overcome these barriers.

Multimedia Principles - Signaling. Explore how using voice and visual cues can help your learners focus, organize, and process your content.

This lesson focuses on the affective domain, which refers to attitudes of awareness, interest, attention, concern and responsibility. Users quiz themselves on their basic understanding of the content.

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

Learners practice their communication skills in this scenario by reading a map, listening to traffic reports, and writing directions for a new delivery route. This activity has audio content.

The learner examines various methods of testing antifreeze. This object has audio content.

Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.

In this interactive object, learners follow step-by-step instructions for reducing algebraic fractions so that they can then be multiplied. This activity has audio content.

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 highly interactive and animated object, learners follow a step-by-step process to reduce algebraic fractions, which contain no addition or subtraction, to their simplest, most elementary form. Immediate feedback is provided. This activity has audio content.

In this animated and interactive object, learners follow oral directions in the workplace. They complete their task within a time limit. This object has audio content.

Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.

Learners put themselves in the place of people new to a community. They listen to a woman describing potential neighbors and make judgments about what they’ve heard. They then learn more about the same people and decide if their initial judgments were accurate. This activity has audio content.

The learner visits a Chinese restaurant to learn how to order from the menu in Mandarin Chinese. This activity has audio content.

In this interactive and animated object, learners follow instructions for finding the lowest common denominator for a group of algebraic fractions. Immediate feedback is provided. This activity has audio content.

In this animated activity, learners examine the circuitry in a DC variable speed drive that causes the motor to accelerate or decelerate at slow rates. This learning object has audio content.
