Achievement tests are among the most widely used data collection tools to measure the knowledge and skill levels of individuals. For this reason, the existence of valid and reliable achievement tests that can perfectly reveal the competencies that a person should have in any discipline is of great importance. The purpose of this research is to…

STACK is an online testing system that can automatically assess mathematical formulae. When working with STACK on a smartphone, inputting mathematical formulae is time-consuming; therefore, to solve this problem a mathematical formula input interface for smartphones has been developed based on the flick operation. However, since the time of…

With the development of information technology, blended learning has been widely used in the education field, and the evaluation of blended learning effect has become one of the research hotspots. Taking the automobile theory course as an example, a blended learning process with online and offline is designed, and the main learning behaviors that…

Acid-base chemistry, and in particular the Lewis acid-base model, is foundational to understanding mechanistic ideas. This is due to the similarity in language chemists use to describe Lewis acid-base reactions and nucleophile-electrophile interactions. The development of artificial intelligence and machine learning technologies has led to the…

Analyses that reveal how treatment effects vary allow researchers, practitioners, and policymakers to better understand the efficacy of educational interventions. In practice, however, standard statistical methods for addressing heterogeneous treatment effects (HTE) fail to address the HTE that may exist "within" outcome measures. In…

Purpose: Based on the general formula, which depends on the length and difficulty of the test, the number of respondents and the number of ability levels, this study aims to provide a closed formula for the adaptive tests with medium difficulty (probability of solution is p = 1/2) to determine the accuracy of the parameters for each item and in…

To investigate the impact of universal testing accommodations on a computer-based reading comprehension test, accessibility, reliability, and validity were evaluated. Tests with and without accommodations were administered to 131 twelfth-grade students in three U.S. schools. Scores on Curriculum-Based Measurement probes determined groups of…

The COVID-19 pandemic severely disrupted assessment models that were commonplace in the testing industry for decades. As a response to this disturbance, remote proctoring has emerged as a promising and potentially sound alternative to offer examinations, while adhering to public health authority guidelines. However, validity evidence in support of…

Since the onset of the pandemic in 2020, many credentialing organizations have incorporated online remote administration of their examinations to enable continuity of their programs. This paper describes a research study examining several high stakes credentialing examination programs that utilized mixed delivery modes, including online remote…

According to theories of validation, people routinely check incoming information against prior knowledge during comprehension. On these theories, information is validated if it fits with prior knowledge. Some researchers argue that information needs to be successfully validated before being incorporated into the situation model. We report five…

A common practical challenge is how to assign ability estimates to all incorrect and all correct response patterns when using item response theory (IRT) models and maximum likelihood estimation (MLE) since ability estimates for these types of responses equal -8 or +8. This article uses a simulation study and data from an operational K-12…

Technology advancements promote a redefinition of traditional instructional methodologies, as well as the roles of teachers and learners towards an efficient e-learning ecosystem. To date, all existing solutions are combined with the conventional face-to-face learning process. However, the latter can be unexpectedly hindered in some emergency…

Purpose: This study explores the roles of morphological skills (Morphological Awareness, Morphological-Syntactic-Knowledge,Morphological-Semantic-Knowledge, and Morphological-Orthographic/Phonological-Knowledge), vocabulary (knowledge of definitions, relationships between words, and polysemous meanings), and syntax in contributing to adolescent…

This study reports on the incorporation of mobile instant messaging (MIM) in assessments, as a collaborative learning tool, to enable students to socially construct knowledge and develop their collaborative problem solving competence, while being assessed individually. In particular, this study explores: what is the extent and timing of students'…

Practical programming competencies are critical to the success in computer science (CS) education and go-to-market of fresh graduates. Acquiring the required level of skills is a long journey of discovery, trial and error, and optimization seeking through a broad range of programming activities that learners must perform themselves. It is not…
