Mathematics Stimulus Considerations

Stimulus MaterialsModule Overview

• Define the purpose of stimuli

• Identify types of stimuli

• Apply general guidelines to create stimuli

Different Parts of an Item

OPTIONSThe possible answers from which the student must select.

STEMThe question to which the student must respond.

STIMULUSThe text, source, and or graphic about which the item is written.

Examples of StimuliWhich of the numbers is• A factor of 100.• A multiple of 5. A. 4B. 40C. 50D. 500
