This thesis“A retrospection study on the construct validity of multiple-choice (MC) listening comprehension tests”explores the construct validity of MC listening comprehension tests through examining the test-taking processes of test-takers.

The paper presents the principle of hearing testing technology,such as air conduction test,bone conduction test,masking technology,double ear sonorous blance,short increment sensitivity index,and the audiometer as hearing testing tool.

Krashen and Gary Buck, this paper discusses and analyses the essential aspects of listening strategies, testing efficiency, listening construct, information-processing procedure and various adoptable approaches, in the hope that this may cast important insights on current studies of listening testing.
