Validation of response processes in medical assessment using an explanatory item response model

BMC Medical Education, 2022
Background Response process validation is a crucial source of test validity. The expected cognitive load scale was created based on the reflection of the mental effort by which borderline students solve an item defined by experts. The stem length affects

A global model–measurement evaluation of particle light scattering coefficients at elevated relative humidity

, 2020
. The uptake of water by atmospheric aerosols has a pronounced effect on particle light scattering properties, which in turn are strongly dependent on the ambient relative humidity (RH).

Want-to, have-to, amotivation, grit, self-control, and tolerance ambiguity among university students: latent profile analysis

BMC Psychology, 2023
The current study adopted a person-centered approach to identify distinctive university students’ profiles based on three variables (i.e., three academic motivations, grit, and self-control), regress multiple covariates (i.e., gender, age, study level ...

Incorporating test-taking engagement into the item selection algorithm in low-stakes computerized adaptive tests

Large-scale Assessments in Education, 2023
In low-stakes assessment settings, students’ performance is not only influenced by students’ ability level but also their test-taking engagement. In computerized adaptive tests (CATs), disengaged responses (e.g., rapid guesses) that fail to reflect ...

Evaluation of touch trigger probe measurement uncertainty using FEA [PDF]

, 2006
Evaluation of measurement uncertainty is an essential subject in dimensional measurement. It has also become a dominant issue in coordinate measuring machine (CMM) even though its machine performance has been well accepted by many users.

A structural equation modeling approach for examining position effects in large-scale assessments

Large-scale Assessments in Education, 2017
Position effects may occur in both paper–pencil tests and computerized assessments when examinees respond to the same test items located in different positions on the test.

Development of a novel virtual coordinate measuring machine [PDF]

, 2009
Existing VCMMs (virtual coordinate measuring machine) have been mainly developed to either simulate the measurement process hence enabling the off-line programming, or to perform error analysis and uncertainty evaluation. Their capability and performance
