In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
Automotive Electrical Systems: VAT-40 Starting System Test
In this highly interactive and animated object, learners examine the VAT-40 battery starting and charging system tester and study how the tester is used to diagnose vehicle starting system problems. This object has audio.
Simplifying Algebraic Fractions that Contain No Addition or Subtraction
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 interactive object, learners review the major parts of the skeletal system by clicking on the correct term as each bone or joint is highlighted on a skeleton.
Learners review normal conditions that are associated with aging. Changes are highlighted in the cardiovascular, musculoskeletal, respiratory, gastrointestinal, urinary, reproductive, endocrine, nervous, and sensory systems.
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.
Robotic welding allows welders to create more consistent and higher quality welds. But, it requires you to understand the terminology associated with its programs. Watch this module to review terminology associated with robotic arc welding and the weaving process.
Nine Principles of Good Practice for Assessing Student Learning: Where Do I Stand?
In this interactive object, instructors use an extensive inventory to assess their beliefs and uses of assessment. The inventory is based on the work of educators supported by the American Association of Higher Education Assessment Forum in 1996.
In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.
Learners view videos of law enforcement and corrections officers describing their jobs and the opportunities in their fields. Because this object contains large video files, it is best viewed using a high band width connection. Low band widths will result in longer download time and video delays.
Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.
Learners watch a video of a walk around inspection of a rough terrain lift truck from front to rear. Note: This object contains video clips. High-speed Internet is highly recommended.
