The original purpose of this blog was to share information about AECT (Association for Educational Communications and Technology - see http://www.aect.org) and solicit comments and feedback about the directions and activities of AECT. Now I am posting things that strike me as worthy of attention and comment. You can send me private comments at email@example.com or post comments to the blog.
Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. [Clarification Statement: Examples of devices that use electric and magnetic forces could include electromagnets, electric motors, or generators. Examples of data could include the effect of the number of turns of wire on the strength of an electromagnet, or the effect of increasing the number or strength of magnets on the speed of an electric motor.] [Assessment Boundary: Assessment about questions that require quantitative answers is limited to proportional reasoning and algebraic thinking.]
