Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.

In this learning activity you'll build a resistor's color code based on the bands.

In this screencast, students demonstrate an understanding of summary writing by reading step-by-step instructions and then summarizing short paragraphs. Examples of summaries that are poorly written, as well as those that are written well, are included.

In this screencast, learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.

In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.

In this interactive object, students complete progressively more difficult exercises as a way to improve their ability to recognize resistor color code values.

The learner will identify the three steps in the writing process and the elements in each step.

In this learning activity you'll review the four main purposes for writing documents: expressive, literary, persuasive, and reality.

The learner will distinguish effective from ineffective approaches to writing instructions.

In this screencast, you'll examine writing a sentence outline using complete sentences for headings, subheadings, main points, and subpoints.

In this learning activity you'll apply directions to follow when writing clear "how-to" instructions.

In this learning activity you'll review the format for a five-paragraph essay, which is the second part of the GED Writing Test.

In this learning activity you'll create a free writing document on a topic.

Students examine how to interpret resistor color code bands to determine resistance values and tolerance ranges. This interactive learning object has audio content and includes exercises.

In this document you'll review drill press work-holding devices.

In this module, you'll build upon the concepts Understanding and Writing Pseudocode: The Basics, by learning new techniques and terms to make your pseudocode more complete.

The learner explores the purpose of organizational mission statements and practices writing a statement that contains the four elements outlined.

In this learning activity, we’ll explore how async and await is used in mobile programming to allow multiple tasks to happen at once.
