Item analysis is an integral part of operational test development and is typically conducted within two popular statistical frameworks: classical test theory (CTT) and item response theory (IRT). In this digital ITEMS module, Hanwook Yoo and Ronald K. Hambleton provide an accessible overview of operational item analysis approaches within these…

This study determined the psychometric properties of the examination items in 2011 Basic Education Certificate Examination for Basic Science. The design adopted was survey research design. The instrument for data collection was the 2011 Delta State Basic Education Certificate Examination (BECE) in Basic Science Multiple Choice Test Items. The IRT…

Over the past decade, large-scale testing programs have employed technology-enhanced items (TEI) to improve the fidelity with which an item measures a targeted construct. This paper presents findings from a review of released TEIs employed by large-scale testing programs worldwide. Analyses examine the prevalence with which different types of TEIs…

Despite social justice leadership receiving an increasing amount of attention by researchers, a methodological imbalance with qualitative inquiries dominating the existing empirical literature base persists. Compounding this issue is the lack of a discipline-specific, quantitative instrument made for the exact purpose of exploring the nature of…

Contingent argument-based approaches to validity require a unique argument for each use, in contrast to more prescriptive approaches that identify the common kinds of validity evidence researchers should consider for every use. In this article, we evaluate our use of an approach that is both prescriptive "and" argument-based to develop a…

The aim of this study was to investigate the quality of the Annual National Assessment (ANA) Grade 6 Mathematics assessment instrument, administered in the year 2012 guided by the main question: to what extent does the 2012 Grade 6 Mathematics assessment instrument provide meaningful and consistent information for making appropriate…

Researchers who study any intervention must rule out potential alternative explanations for their results by establishing that the program being investigated is implemented with fidelity. Various instructional practices are attributed to the Montessori Method because the term is not legally protected, meaning any school can say it is Montessori…

The "Next Generation Science Standards" calls for new assessments that measure students' integrated three-dimensional science learning. The National Research Council has suggested that these assessments utilize a combination of item formats including constructed-response and multiple-choice. In this study, students were randomly assigned…

Recent research in multidimensional item response theory has introduced within-item interaction effects between latent dimensions in the prediction of item responses. The objective of this study was to extend this research to bifactor models to include an interaction effect between the general and specific latent variables measured by an item.…

Statistical literacy refers to two interrelated components: people's ability to interpret and critically evaluate statistical information, and their ability to discuss or communicate their reactions to statistical information. The ability to read and interpret graphical displays is part of statistical literacy because much of the statistical…

In equating, when common items are internal and scoring is conducted in terms of the number of correct items, some pairs of total scores ("X") and common-item scores ("V") can never be observed in a bivariate distribution of "X" and "V"; these pairs are called "structural zeros." This simulation…

The ongoing debates about the effects of human population growth (HPG) is one of the concepts in education for sustainable development (ESD). Beliefs toward HPG are an important construct for teacher education because beliefs potentially interfere with their instructional practices and students' beliefs, attitudes and behaviors. Accordingly, this…

Assessments built on a theory of learning progressions are promising formative tools to support learning and teaching. The quality and usefulness of those assessments depend, in large part, on the validity of the theory-informed inferences about student learning made from the assessment results. In this study, we introduced an approach to address…

Team teaching is an innovative method to engage the large group and make lectures more interesting. The aim of the study is to evaluate the impact of team teaching in first year biochemistry lecture classes. After obtaining ethical clearance, 150 first year medical undergraduate students participated in the study on a voluntary basis. Topic…

The aim of the study is to develop an achievement test consisting of the questions in verbal intelligence games whose validity and reliability have been ensured and which are in accordance with the learning outcomes of the states of substance and knowing the properties of substance via the five senses taking place in the unit "Let's Know…
