Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.
This is a learning object describing what a learning object actually is. This will take us through the definition of a learning object and break down each segment to help clarify the mystery of this wonderful online tool for teaching and learning.
The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.
Learners click on the root word of a medical term in the left-hand column and drag it to its definition in the right-hand column. There is a time limit, so students will need to train themselves to recognize these root words quickly. Students may repeat the activity as often as they wish. A total of 74 terms are given in random order.
In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.
