2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a mounting wedge. A short quiz to test your ability to correctly read this information follows.
In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.
In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.
In this interactive object, learners examine the characteristics of effective visual displays. This activity is designed primarily for instructional assistants.
In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.
Statics - Trig: The Pythagorean Theorem Using a TI-36XCalculator
In this animated and interactive object, the learner uses a TI-36X calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.
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 a series of interactive exercises, learners identify the parts of a URL, a Web site, and an e-mail memo. Students are given their score at the end of the activity.
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.
