This article describes the development and validation of the new CATSS (Computer Adaptive Test of Size and Strength), which measures vocabulary knowledge in four modalities -- productive recall, receptive recall, productive recognition, and receptive recognition. In the first part of the paper we present the assumptions that underlie the test --…

The first aim of this study was to develop a computer adaptive EFL test (CALT) that assesses test takers' listening and reading proficiency in English with dichotomous items and polytomous testlets. We reported in detail on the development of the CALT, including item banking, determination of suitable item response theory (IRT) models for item…

The importance of student assessment, particularly for summative purposes, has increased greatly over the past thirty years. At the same time, emphasis on including all students in assessment programs has also increased. Assessment programs, whether they are large-scale, district-based, or teacher developed, have traditionally attempted to assess…

Reports on the first phases of an American Council on the Teaching of Foreign Languages project to develop a computerized adaptive test of reading proficiency. The theoretical multidimensionality of the construct is clarified, and its implications for test development, item calibration, and validation procedures are discussed. (Author/SED)

Discusses the possible limitations and the advantages of computer-assisted language testing and several test variables which are of concern in determining test validity. The concept of computer-adaptive testing and its relationship to these variables is described. (SED)

This paper introduces a model of adaptive learning relevant to adult learners of English for academic purposes (EAP) in Australia. Adaptive learning refers to latent variables hypothesized to contribute to optimal performance in the language. The model comprises motivation, self-efficacy, language learning anxiety, language learning strategies,…
