Determining The Difficulty And Discrimination Parameters Of A Mathematics Performance-Based Assessment, Abraham Gyamfi, Douglas G. Wren
Determining The Difficulty And Discrimination Parameters Of A Mathematics Performance-Based Assessment, Abraham Gyamfi, Douglas G. Wren
Educational Leadership & Workforce Development Faculty Publications
Performance-based assessment (PBA) is different from traditional testing methods in that PBA presents real-life problems for students to solve by integrating critical thinking with their content knowledge and skills. Implementing PBA regularly in mathematics classes is associated with improved student achievement and motivation to learn; however, there are concerns about the general lack of psychometric data to support the use of performance assessments. To address such concerns, this study applied item response theory to estimate the difficulty and discrimination indices of items that comprised a newly developed mathematics PBA. Data were collected by administering the PBA to 750 senior high …
A Study Of The Robustness Of The Three-Parameter Item Response Model, James B. Flynn
A Study Of The Robustness Of The Three-Parameter Item Response Model, James B. Flynn
Psychology Theses & Dissertations
Simulation techniques were employed to investigate the use of the three-parameter item response model on psychological test data which violated the model's assumptions of large sample sizes, long tests and test unidimensionality. The accuracy of the person ability and item characteristic curve parameter estimates derived by the three-parameter item response model was evaluated. Data sets and distributions of person ability and item characteristic curve parameters were generated using a computer-based algorithm, AVRAM (Ree, 1980), which employs the three-parameter logistic probability equation described by Birnbaum (1968). A computer software package, LOGIST5 (Wingersky, Burton & Lord, 1982), which utilizes the three-parameter logistic …
