Previous characterizations of rumination do not account for why a reflective style of ruminative response to negative mood, as opposed to a brooding style, is linked with greater creativity--especially when indecision is high. Moreover, less is known about ruminative responses to positive mood. The purpose of this investigation is to demonstrate…

This study evaluated the psychometric properties of the Scale of Treatment Perceptions (STP), a measure of treatment acceptability targeting skill-building interventions for Autism Spectrum Disorder (ASD). This scale utilizes a strength-based approach to intervention assessment, and was established by modifying the Behavior Intervention Rating…

Proactive preliminary minimum sample size determination can be useful for the early planning stages of a latent variable modeling study to set a realistic scope, long before the model and population are finalized. This study examined existing methods and proposed a new method for proactive preliminary minimum sample size determination.

The present study reports the development of a brief, quantitative, web-based, psychometrically sound measure--the Generalized Acceptance of EvolutioN Evaluation (GAENE, pronounced "gene") in a format that is useful in large and small groups, in research, and in classroom settings. The measure was designed to measure only evolution…

The purpose of this study is to determine the language equivalence and the validity and reliability of the Turkish version of the "Web-Based Learning Platform Evaluation Scale" ("Web Tabanli Ögrenme Ortami Degerlendirme Ölçegi" [WTÖODÖ]) used in the selection and evaluation of web-based learning environments. Within this scope,…

Differential granting of extra-examination time (EET) is commonly based on learning disabilities (LD) status: EET is granted to LD examinees and is denied to nondisabled examinees. We argue that LD serves as a proxy for the extent to which time limitation affects the examinee's test score (e). Hence, the validity of the LD-based EET granting…

In educational research that calls itself empirical, the relationship between validity and reliability is that of trade-off: the stronger the bases for validity, the weaker the bases for reliability (and vice versa). Validity and reliability are widely regarded as basic criteria for evaluating research; however, there are ethical implications of…

Prior research shows that learners have idiosyncratic responses to error-correction procedures during instruction. Thus, assessments that identify error-correction strategies to include in instruction can aid practitioners in selecting individualized, efficacious, and efficient interventions. The current investigation conducted an assessment to…

The high school curriculum sometimes seems like a disconnected collection of topics and techniques. Theorems like the factor theorem and the remainder theorem can play an important role as a conceptual "glue" that holds the curriculum together. These two theorems establish the connection between the factors of a polynomial, the solutions…

Objective: Limited time and resources necessitate the availability of accurate, inexpensive and rapid diagnostic aids for Autism Spectrum Disorder (ASD). The Autistic Behavioural Indicators Instrument (ABII) was developed for this purpose, but its psychometric properties have not yet been fully established. Method: The clinician-rated ABII, the…

This investigation explored the extent to which a newly constructed instrument, the CLASS Action Survey (CLAS), was able to accurately measure the qualities of a specialized course, the Crystallized Learning and Academic Study System (CLASS) and its stated goals: (1) to increase college students' academic mindedness, (2) to challenge…

Introduction: In secondary education, students' low achievement and engagement in mathematics are closely related to their attitudes towards the subject. Despite the international body of research, an exhaustive literature review of the existing instruments for measuring it draws attention to the inconsistency in the definition and corresponding…

This research examines what practitioners in vocational education and training (VET) organisations and external auditors judge to be the key issues in the current and future use of e-assessment. Applying the framework of legitimacy theory, the study examined the tensions around the use and growth of e-assessment in training organisations, and…

Testing organization needs large numbers of high-quality items due to the proliferation of alternative test administration methods and modern test designs. But the current demand for items far exceeds the supply. Test items, as they are currently written, evoke a process that is both time-consuming and expensive because each item is written,…

Selecting assessments for adults who struggle with reading can be difficult because few literacy measures used by reading researchers have been normed on this population, leaving uncertainty regarding the validity of these tests for adult learners. This study focused on the performance of 116 adults reading between the 3rd and 8th grade levels on…
