Pyp And Myp Student Performance On The International Schools’ Assessment (Isa), Ling Tan, Yan Bibby
Pyp And Myp Student Performance On The International Schools’ Assessment (Isa), Ling Tan, Yan Bibby
Dr Ling Tan
This study, undertaken by the Australian Council for Educational Research (ACER), investigated how International Baccalaureate (IB) students enrolled in the Primary Years Programme (PYP) and Middle Years Programme (MYP) performed on the International Schools’ Assessment (ISA), relative to non‐IB students. The ISA assesses student performance in Grades 3 to 10 across four domains: Math Literacy, Reading, Narrative Writing, and Expository Writing. The math and reading components of the assessment are based on the reading and mathematical literacy frameworks of the HOECD'sProgramme for International Student Assessment (PISA)H. The study sample included IB students (N=23,575) and non‐IB students ( …
Fit-To-Model Statistics For Evaluating Quality Of Bayesian Student Ability Estimation, Ling Tan
Fit-To-Model Statistics For Evaluating Quality Of Bayesian Student Ability Estimation, Ling Tan
Dr Ling Tan
Bayesian ability estimation is a statistical inferential framework constructed from a measurement model and a prior knowledge model. It is attractive in practice because Bayesian estimation methods offer an elegant way to incorporate appropriate knowledge on target ability distribution in order to improve the accuracy of ability estimation, when there are uncertainties or errors in observable data. One hurdle for applying Bayesian-based methods is evaluating the validity of Bayesian ability estimates at individual-level. This study investigated a class of fit-to-model statistics for quantifying the evidence used in learning Bayesian estimates. The relationship between fit-to-model statistics and root mean square error …
