Educational tests often have a cluster of items linked by a common stimulus ("testlet"). In such a design, the dependencies caused between items are called "testlet effects." In particular, the directional testlet effect (DTE) refers to a recursive influence whereby responses to earlier items can positively or negatively affect…

A C-Test is a gap-filling test for measuring language competence in the first and second language. C-Tests are usually analyzed with polytomous Rasch models by considering each passage as a super-item or testlet. This strategy helps overcome the local dependence inherent in C-Test gaps. However, there is little research on the best polytomous…

Students who are self-regulated leaners have been reported to perform more successfully in higher education institutions (HEIs). Therefore, instruments that can monitor students' motivation and learning have been devised and implemented. The aims of this work were to investigate the dimensionality of the motivated strategies for learning…

As chemistry education, and science education more broadly, have shifted to emphasize realistic scientific practices as an important component of education, a number of researchers have used the Students' Understanding of Models in Science (SUMS) instrument to assess students' knowledge about scientific models and modelling. SUMS has also been…

The Transtheoretical Model (TTM) conceptualizes change as a process with five identifiable stages. Each stage has psychological characteristics that are manifestations of an underlying continuum of change. Surprisingly few studies have applied the TTM to understand the process involved with academic development. The objective of this study was to…

The study aimed to develop and validate an assessment framework of multidimensional scientific competencies for seventh-grade students in the northeastern region of Thailand. A total of 289 samples with three different scientific competency levels were randomly selected to participate as test-takers. The design-based research encompassing four…

The study was conducted to analyze the items about the ability of high school students diagram representation and obtain Item Curve Characteristic. Grid test instruments are compiled based on competencies and indicators of diagram representation which are then used to compile items. The test instrument consisted of five items and was validated by…

Distractor analyses are routinely conducted in educational assessments with multiple-choice items. In this research report, we focus on three item response models for distractors: (a) the traditional nominal response (NR) model, (b) a combination of a two-parameter logistic model for item scores and a NR model for selections of incorrect…

The factor structure of the Teacher-Child Rating Scale (T-CRS 2.1) was examined using confirmatory factor analysis (CFA). A cross-sectional study was carried out on 68,497 children in prekindergarten through Grade 10. Item reduction was carried out based on modification indices, standardized residual covariance, and standardized factor loadings. A…

Introduction: The focus of our research converges on the analysis of attitudes and the prediction of the behavior of university students towards the inclusion of students with disabilities in university. The evaluation of attitudes and the prediction of behavior are complex, but it is fundamental because of the decisive impact they have on the…

This study analysed polytomous items' psychometric properties according to nonparametric item response theory (NIRT) models. Thus, simulated datasets--three different test lengths (10, 20 and 30 items), three sample distributions (normal, right and left skewed) and three samples sizes (100, 250 and 500)--were generated by conducting 20…

Diagnostic classification models (DCMs) classify examinees based on the skills they have mastered given their test performance. This classification enables targeted feedback that can inform remedial instruction. Unfortunately, applications of DCMs have been criticized (e.g., no validity support). Generally, these evaluations have been brief and…

The purpose of this study is to further enhance the existing reliability and validity evidence related to the School Implementation Scale (SIS) and its use for evaluating the implementation of different integrated academic and behavior tiered Response-To-Intervention (RTI) models. Previous methodology conducted for validation of the instrument has…

This study is to investigate whether "My Class Activities" (MCA; Gentry & Gable, 2001a), an instrument developed to measure students' perceptions of their classroom activities, yields valid data when used with elementary students in China after translation into Chinese. The four factors measured by the instrument (Interest,…

This paper examines how different test methods may tap different aspects of second language knowledge. It employs multiple-choice (MC) and constructed response (CR) items which yield distinct or convergent information in the computer delivered testing of English in its presentation of this factor. In order to examine the effects of test method, a…
