Determining The Academic Achievement Of English Language Learners (Ells) By Using Additional Measures Of Growth, Adriana Maria Marin Aug 2015

Determining The Academic Achievement Of English Language Learners (Ells) By Using Additional Measures Of Growth, Adriana Maria Marin

Dissertations

Accountability measures employed in the country to determine the academic achievement of all the student population rely solely on the results obtained on the standardized tests. Such measures have often placed English language learners’ (ELLs) at risk of academic failure despite the fact that research on second language acquisition (SLA) has stated the complexity involved in the learning/acquisition process of a target language. Scholars have also discussed the influence accountability measures and the issues with the validity of the tests implemented to assess ELLs may have on such results. Therefore, in an effort to obtain a more comprehensive idea of …

Extending An Irt Mixture Model To Detect Random Responders On Non-Cognitive Polytomously Scored Assessments, Mandalyn R. Swanson

Dissertations, 2014-2019

This study represents an attempt to distinguish two classes of examinees – random responders and valid responders – on non-cognitive assessments in low-stakes testing. The majority of existing literature regarding the detection of random responders in low-stakes settings exists in regard to cognitive tests that are dichotomously scored. However, evidence suggests that random responding occurs on non-cognitive assessments, and as with cognitive measures, the data derived from such measures are used to inform practice. Thus, a threat to test score validity exists if examinees’ response selections do not accurately reflect their underlying level on the construct being assessed. As with …
