Short answer test items:

CAN give insight into student thinking.

However, the teacher observes the result of the student’s thinking but not the process!

Essays and other extended-response items:

Provide a product as evidence of student thinking

Permits the teacher to see the logic of arguments, the organization of the response, and their conclusions.

AssessmentsAssessments

Purpose Sample knowledge with maximum efficiency and reliability

Assess thinking skills and/or mastery of how a body of knowledge is structured

Assess knowledge during instruction

Assess ability to translate knowledge and understanding into action

Student’s Response

Read, evaluate, select

Organize, compose

Oral answer Plan, construct and deliver an original response

Major Advantage

Efficiency—can administer many items per unit of testing time

Can measure complex cognitive outcomes

Joins assessment and instruction

Provides rich evidence of performance skills

Influence on Learning

Overemphasis on recall encourages memorization; can encourage thinking skills if properly constructed

Encourages thinking and development of writing skills

Stimulates participation in instruction, provides teacher immediate feedback on effectiveness of teaching

Emphasizes use of available skill and knowledge in relevant problem contexts

STUDENT Lynn Gregory DATE 9/22/2007

OBSERVER J. Ricketts

Lynn entered the room in an orderly manner and moved directly for her

desk. She began preparing for class by taking out her homework and a

pencil. Lynn then became interested in a conversation that was occurring

between two students beside her. She left her desk and became engaged in

the conversation. She quickly became animated and, when the bell rang, had

difficulty settling back down. For several minutes, she repeatedly shifted her

focus from the teacher to the students beside her, at times whispering to

them. Only after being spoken to by the teacher was Lynn able to fully focus

on the lesson at hand.
