Learners identify types of activities in the Plan-Do-Check-Act Cycle and watch how the cycle works on the job.

In this interactive and animated object, learners examine the duty cycle of a squarewave produced by a multivibrator using a 555 IC (integrated circuit). A brief quiz completes the activity.

Learners examine the three steps of a processor scan cycle.

In a series of three interactive exercises, learners explore the relationship between process cycle time and defect detection, and between process cyle time and smaller batch sizes. The techniques of lean/JIT are applied to achieve the continuous improvement (kaizen) goal of reducing inventory by pursuing one-piece flow.

Explore The Study Cycle – an approach that research and experience shows is the best and most efficient way to study

In this animated object, learners examine the different phases of a cell's life.

Students read how the Plan-Do-Check-Act Cycle is used in problem-solving and process improvement. In an interactive exercise, students organize process improvement steps following this model.

In this learning activity you'll plot GDP data on a graph and determine a phase of the business cycle.

In this interactive object, learners study animal estrous cycle lengths. They then test their knowledge in three exercises.

In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.

In this learning activity you'll see and hear basic Hmong phrases.

In this interactive object, learners practice using the phrasal verbs "get on," "get over," "get away," "get down to," and "get away with."

In this learning activity you'll explore various forms of the verb "do."

In this learning activity you'll practice writing the correct verb form in this interactive exercise.

The learner identifies if phrasal verbs are used correctly in a sentence. If they are not used correctly, the student substitutes the correct answer.

Students read the definitions of "raise" and "rise," two verbs that are often confused. They then enter the correct tense of each verb in a variety of sentences.

In this interactive lesson, learners study examples of the expressions "a few" and "a little" with count and noncount nouns. They practice using these expressions in a drag-and-drop exercise of 20 sentences.

In this interactive lesson, learners study the use of "many" and "much" with nouns that can be counted and nouns that cannot. They then practice using these words in a drag-and-drop exercise.

In this learning activity you'll review the usage of "borrow" and "lend."
