Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.
In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.
Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
Learners examine the functions of the three types of memory used by an Allen-Bradley SLC-500 programmable logic controller: the Executive ROM, Scratch Pad, and Processor File.
In this animated object, learners examine the operation and programming requirements of a PLC Examine-Off instruction. A brief quiz completes the activity.
In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.
Learners examine the two methods used by programmable logic controllers to perform a counting operation using addition or counter instructions. A brief quiz completes the activity.
The Importance of Attire in Early Childhood Education
Learners read about the types of clothing considered appropriate for a childcare setting. This activity is designed for students enrolled in an early childhood education program.
Learners read definitions of terms related to legal, insurance, and advocacy issues regarding the elderly. At the end of the activity, learners test their knowledge in three matching exercises. Some of the programs and groups discussed are Medicare, Medicaid, Social Security, long-term care insurance, OBRA, SSI, and CWAG.
Learners read about the types of clothing considered appropriate for a school setting. This activity is designed for students enrolled in an instructional assistant program.
In this interactive object, learners change the amount of money received from tax revenue and the amount spent on federal programs as they calculate how fiscal policy affects the gross domestic product (GDP), unemployment, inflation, the annual deficit, the national debt, and interest on the national debt.
Users read about how course competencies relate to program outcomes. They listen to the testimonies of three students who describe learning activities that prepared them for the world of work. In a matching exercise, learners distinguish between course competencies and program outcomes.
