Trialling Of Test Items; Is The Data A Reliable Predictor Of Final Test Performance?, Ross Hudson
Trialling Of Test Items; Is The Data A Reliable Predictor Of Final Test Performance?, Ross Hudson
Dr Ross Hudson
Trialling is seen as a necessary first step in producing a reliable valid assessment tool. However, how reliable is the trialling result in terms of predicting population test performance?

Impact Of Different Item Location In Common-Item Test Equating, Luc Le
Dr Luc Tu Le
This study used real data and simulation data to investigate the impacts of different item location in common-item test equating. The real data set included responses of about 150 000 students to a generic skills test from a university survey in Columbia in 2011, where each student was assigned randomly to one of four linked test forms. Each form consisted of two of three Critical Reasoning clusters and two of three Quantitative Reasoning clusters (20 items in each cluster). The results of an analysis using Item Response Theory clearly showed that items could become more difficult when located towards the …

Which Form Of Assessment Provides The Best Information About Student Performance In Chemistry Examinations?, Ross Hudson, David Treagust
Dr Ross Hudson
Background: This study developed from observations of apparent achievement differences between male and female chemistry performances in a state university entrance examination. Male students performed more strongly than female students, especially in higher scores. Apart from the gender of the students, two other important factors that might influence student performance were format of questions (short-answer or multiple-choice) and type of questions (recall or application). Purpose: The research question addressed in this study was: Is there a relationship between performance in state university entrance examinations in chemistry and school chemistry examinations and student gender, format of questions--multiple-choice or short-answer, and conceptual …
Adaptive Testing For Psychological Assessment: How Many Items Are Enough To Run An Adaptive Testing Algorithm?, Michaela Wagner-Menghin, Geoff Masters
Adaptive Testing For Psychological Assessment: How Many Items Are Enough To Run An Adaptive Testing Algorithm?, Michaela Wagner-Menghin, Geoff Masters
Prof Geoff Masters AO
Although the principles of adaptive testing were established in the psychometric literature many years ago (e.g., Weiss, 1977), and practice of adaptive testing is established in educational assessment, it is not yet widespread in psychological assessment. One obstacle to adaptive psychological testing is a lack of clarity about the necessary number of items to run an adaptive algorithm. The study explores the relationship between item bank size, test length and measurement precision. Simulated adaptive test runs (allowing a maximum of 30 items per person) out of an item bank with 10 items per ability level (covering .5 logits, 150 items …
