The first step in instrument development is conceptualization, which involves defining the construct and the variables to be measured. Use the International Classification of Functioning, Disability and Health (ICF) (WHO, 2011) or the model by Wilson and Clearly (1995) as a framework for your conceptual model. When the construct is not directly ...

Each card will contain two beats of melody or rhythm. Students will begin in the center by playing each card individually. If they have trouble playing anything, they should ask someone in their group for help or raise their hand and wait for you. Then, they can begin arranging the cards to create their own rhythm and/or melodic patterns.
The Rover and Its Onboard Toolkit About the size of a golf cart, NASA's Volatiles Investigating Polar Exploration Rover, or VIPER, is ideal for traversing the Moon's South Pole. Through extensive testing on prototype units here on Earth, NASA teams have come up with the right solutions for operating NASA's first lunar mobile robot on the […]
This self-portrait of NASA's Mars Exploration Rover Opportunity comes courtesy of the Sun and the rover's front hazard-avoidance camera. The dramatic snapshot of Opportunity's shadow was taken as the rover moved into Endurance crater. The image was taken on sol 180 (July 26, 2004), a date that marked double the rover's primary 90 …
Many limiting factors are imposed within the mineral exploration industry [104], and much of exploration targeting is a low-validity task, owing to its low base-rate of success (e.g. [64 ...
