Vocabulary has been recognized as an important area in understanding the language development of preschoolers. Computerized Adaptive Test (CAT) is a form of computerized administered test. It adapts to different ability levels of individual test‐takers to yield high testing efficiency.
This study is to apply Computerized Adaptive Testing (CAT) technology to develop a Receptive Vocabulary Test for Hong Kong‐Cantonese and China‐Mandarin young children aged from 2.5 to 6.5.
Test item construction, field test and psychometric evaluation are the essential steps for the test validation process. Test items are drawn from four categories of source and undergo content validation process by expert panel.
More than 3000 vocabularies have been collected from Chinese language database, vocabulary tests, dictionaries, story books and textbooks. The list was reduced to 600 with reference to expert judgement.
Test plate construction will be conducted with the resulted vocabulary list. With further validation steps, this ongoing study will provide an improved and evidence‐based clinical tool for preschool receptive vocabulary assessment.
