Cognitive ability is closely associated with the acquisition of programming skills, and enhancing learners' cognitive ability is a crucial factor in improving the efficacy of programming education. Adaptive feedback strategies can provide learners with personalized support based on their learning context, which helps to stimulate their interest…

In educational and psychological research, we are often interested in discrete latent states of individuals responding to an assessment (e.g., proficiency or non-proficiency on educational standards, the presence or absence of a psychological disorder). Diagnostic classification models (DCMs; also called cognitive diagnostic models [CDMs]) are a…

We analyze a 12-item version of Raven's Standard Progressive Matrices test, traditionally scored with the sum score. We discuss some important differences between assessment in practice and psychometric modelling. We demonstrate some advanced diagnostic tools in the freely available R package, dexter. We find that the first item in the test…

In this digital ITEMS module, Dr. Jeffrey Harring and Ms. Tessa Johnson introduce the linear mixed effects (LME) model as a flexible general framework for simultaneously modeling continuous repeated measures data with a scientifically defensible function that adequately summarizes both individual change as well as the average response. The module…

The documentation of test takers' achievements has been accomplished through large-scale assessments to find general information about students' language ability. To remove subjectivity, Cognitive Diagnostic Assessment (CDA) has recently played a crucial role in perceiving candidates' latent attribute patterns to find multi-diagnostic information…

The aim of this article is to propose a method for development of concept map in web-based environment for identifying concepts a student is deficient in after learning using traditional methods. Direct Hashing and Pruning algorithm was used to construct concept map. Redundancies within the concept map were removed to generate a learning sequence.…

Researchers suggest students in early elementary grade levels are active learners and creators and need to be exposed to science, technology, engineering, and mathematics (STEM) curriculum. The need for student understanding in STEM curriculum is well-documented, and positive results in robotics and computer programming are leading researchers and…

Awareness of the history of health education efforts is important for health educators. The VD Radio Project, developed in the middle of the 20th century, was a cooperative effort of the United States Public Health Service and Columbia University designed to encourage people to be tested for sexually transmitted infections. How the campaign came…
