Learners read the characteristics of the TTL series. Examples are given and subfamilies are compared.

In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

In this learning activity, you’ll explore the characteristics of common, carbon steel shielded metal arc welding electrodes, which fall under American Welding Society specification A5.1.

Students read about the phenomenon of people trying to do their best to be good subjects when participating in research.

In this learning object you'll review information for layman, executive, expert, technician and operator audiences for writing technical publications.

In this learning module you'll become familiar with different types of GTAW electrodes.

Learners examine what defines a fungus and read how fungi differ from animals and plants.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.

Learners identify maintenance roles and match statements characteristic of each role. This activity has audio content.

Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.

Learners examine the phases and characteristics of the reality shock experienced by nurses. They also identify strategies to deal with reality shock and with the transition from student nurse to registered nurse.

The operation and characteristics of an absolute optical encoder used in automation applications are presented.

Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.

Learners study the operation and characteristics of an incremental optical encoder used in automated manufacturing applications. A brief quiz completes the activity.

Learners identify conflict resolution styles while becoming familiar with definitions, characteristics, and motivations for using these styles.

Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.

In this interactive object, learners read the characteristics of each stage of labor and delivery. They then identify the stages in a multiple-choice assessment.

Material condition modifiers may be applied to tolerances for geometric characteristics of features of size. A feature of size is one that can be measured across two opposing points, either internally or externally.

Learners examine the main characteristics of the four financial statements required in accounting: the income statement, the owner's equity statement, the balance sheet, and the statement of cash flow.
