Studying Mathematical Literacy through the Lens of Pisa's Assessment Framework

چکیده
Accurate interpretations of large-scale assessment results and sound judgments about students’ mathematical literacy depend on these assessments’ validity and reliability. One important type of evidence towards this validation is the dimensionality analysis, which explores the conformity between the intended factorial structure (related closely to defining a construct –e.g., mathematical literacy, and its perception) and the statistical structure of the test results. This study investigates the dimensionality of mathematical literacy in PISA. Our results show that the structural relationship between PISA’s theoretical (cognitive) and score interpretation frameworks is not at an expected level. These results have important implications for the way mathematical literacy is assessed from mathematics education and psychometric perspectives.

Iranian EFL Teachers' Language Assessment Literacy (LAL) under an Assessing Lens
Despite being trained in pre-service teacher education programs, most EFL teachers are underprepared when faced with language assessment-related activities. Part of the problem emanates from the fact that Language Assessment Literacy (LAL) as a construct has not been well defined by experts. The purpose of this study was to pinpoint the components of LAL in the Iranian EFL context using an adap...
متن کاملAnalyses of model fit and robustness. A new look at the PISA scaling model underlying ranking of countries according to reading literacy.
This paper addresses methodological issues that concern the scaling model used in the international comparison of student attainment in the Programme for International Student Attainment (PISA), specifically with reference to whether PISA's ranking of countries is confounded by model misfit and differential item functioning (DIF). To determine this, we reanalyzed the publicly accessible data on...
متن کاملFeatures of Language Assessment Literacy in Iranian English Language Teachers' Perceptions and Practices
anguage assessment literacy (LAL), mainly defined as knowledge and skills of language assessment, in the last two decades, has started to receive the attention it deserves. As one of the significant findings, based on a plethora of research, many second language (L2) teachers have been indicated to be professionally incompetent in terms of LAL. To investigate the status of LAL among Ira...
