Many previous studies observed that higher retrospective confidence ratings about memory performance were associated with shorter response times in memory test. Researchers often interpret response time as a measure of retrieval fluency which is an important cue utilized in confidence formation process. However, the drift diffusion model (DDM)…

We propose some theoretical and empirical advances by supplying the methodology for analyzing the factors that influence two sensitive variables when data are collected by randomized response (RR) survey modes. First, we provide the framework for obtaining the maximum likelihood estimates of logistic regression coefficients under the RR simple and…

Response data containing an excessive number of zeros are referred to as zero-inflated data. When differential item functioning (DIF) detection is of interest, zero-inflation can attenuate DIF effects in the total sample and lead to underdetection of DIF items. The current study presents a DIF detection procedure for response data with excess…

This study describes the adaptation of the autism diagnostic observation schedule (ADOS-2) to assess autism spectrum disorder (ASD) in adults with intellectual disability (ID) and hearing loss who communicate primarily visually. This adapted ADOS-2 was applied to residents of specialized therapeutic living communities (n = 56). The internal…

Multiple-response questions are a common feature of survey-based research, as its advantages of information collection are well known. Statistical analysis of the responses, however, tends to be either one or two-dimensional, with the restrictions that this entails. This paper presents a multidimensional analysis protocol that provides the…

Grades are frequently understood as an output of the educational process. However, they may also be an input: receiving a midterm grade may affect student performance in the remainder of the semester. Utilizing a regression discontinuity design to isolate the causal impact of midterm grades on subsequent student performance in the same course, we…

Performance on homework questions was compared with performance on related exam questions querying the same fact or principle, was used to assess the effect of answering online homework questions on subsequent exam performance. A distinctive pattern of performance was found for some students in which superior performance on online homework…

It is necessary to supply proof regarding the construct validity of the scales. Especially, when new scales are developed the construct validity is researched by the Exploratory Factor Analysis (EFA). Generally, factor extraction is performed via the Principal Component Analysis (PCA) which is not exactly factor analysis and the Principal Axis…

Two previous studies mapping university mathematics students' summative assessment diet in the UK revealed a clear picture. In general, there was a dominance of closed book examinations with a strong relationship to departmental league table position. The decade since then has seen many changes in higher education in the UK, particularly in the…

In a world characterized by a formal global consensus on norms of "Education for All," countries face growing social pressures to rationalize their educational institutions around a global and standardized set of best practices. In this context, I argue that national assessments are part of a more general set of organizational structures…

This study examined the concurrent validity of a tummy time questionnaire and time-use diary against an accelerometer measure. Participants were 29 parents and their 6-month-old infants from the Early Movers project in Edmonton, Canada. Tummy time was concurrently measured using a parental questionnaire, a time-use diary, and a validated GENEActiv…

Background: The use of ultrasound as an adjunct to clinical swallowing evaluation provides quantitative physiological and morphological data. As a low-risk procedure, ultrasound imaging can be performed outside of a medical setting. This is particularly important for patients living in rural areas with restricted access to a hospital. Technical…

Creative thinking is found more or less in each individual, and is a skill that can be learned. Creative drama is one of the methods used to acquire this skill. This study examined the effect of applying the creative drama approach for the development of creative thinking skills in students with intellectual disabilities. The study was carried out…

There is an extensive need for school systems to reliably assess the data literacy and data use skills of their educators. To address this need, the current study seeks to refine the NU Data Knowledge Scale (NUDKS) for assessing teacher data literacy for classroom data. A data-based decision-making framework provides the theoretical underpinnings…

Background: Findings from the testing effect literature suggest several ways to achieve testing effects in an authentic classroom, but few consider instructor workload, equity, and resources that determine feasibility and sustainability of testing effect methods in practice. Objective: To determine elements and procedures from the testing effect…
