Purpose: The purpose of this study was to determine the extent to which vowel metrics are capable of distinguishing healthy from dysarthric speech and among different forms of dysarthria. Method: A variety of vowel metrics were derived from spectral and temporal measurements of vowel tokens embedded in phrases produced by 45 speakers with…

As a global measure of precision, item response theory (IRT) estimated reliability is derived for four coefficients (Cronbach's a, Feldt-Raju, stratified a, and marginal reliability). Models with different underlying assumptions concerning test-part similarity are discussed. A detailed computational example is presented for the targeted…

Purpose: This study examined the test-retest stability of select word-retrieval measures in the discourses of people with aphasia who completed a 5-stimulus discourse task. Method: Discourse samples across 3 sessions from 12 individuals with aphasia were analyzed for the stability of measures of informativeness, efficiency, main concepts, noun and…

Social media are ubiquitous and used by millions of people every day. Existing research on social media is primarily descriptive, survey based, and focused on who is using social media and how people and organizations are using the tools. Although many organizations have shown interest in using social media, they often demonstrate uncertainty…

Background: Conceptual understanding is a prerequisite for engineering competence. Concept maps may be effective tools for assessing conceptual knowledge, yet further work is needed to examine scoring methods. Purpose: Our purpose was to evaluate the efficacy of three concept map scoring methods. Traditional scoring requires judges to count…

Schools are social organizations where children came together from different cultures. Creating sense of community is important for schools for the formation of social culture. In schools where sense of community is formed, it is observed that students treat each other with respect, are caring and sharing and have high academic success, and rates…

We assess the consistency of measures of individual local ecological knowledge obtained through peer evaluation against three standard measures: identification tasks, structured questionnaires, and self-reported skills questionnaires. We collected ethnographic information among the Baka (Congo), the Punan (Borneo), and the Tsimane' (Amazon) to…

Purpose: The goal of this study is to explore the psychometric properties of the Parent Rating Scales-V1 (S. K. Millard, S. Edwards, & F. M. Cook, 2009), an assessment tool for parents of children who stutter, and to refine the measure accordingly. Method: We included 259 scales completed prior to therapy. An exploratory factor analysis…

Student attitudes toward mathematics play an important role in the teaching and learning processes of mathematics as positive attitudes correlate with higher student achievement. This paper aims to develop and explore the validity of a Chinese version of the short attitudes toward mathematics inventory (short ATMI) for Taiwanese undergraduates,…

As an alternative to rubric scoring, comparative judgment generates essay scores by aggregating decisions about the relative quality of the essays. Comparative judgment eliminates certain scorer biases and potentially reduces training requirements, thereby allowing a large number of judges, including teachers, to participate in essay evaluation.…

Previous research into the benefits student response systems (SRS) that have been brought into the classroom revealed that SRS can contribute positively to student experiences. However, while the benefits of SRS have been conceptualized and operationalized into a widely cited scale, the validity of this scale had not been tested. Furthermore,…

Although there is a common understanding of instructional sensitivity, it lacks a common operationalization. Various approaches have been proposed, some focusing on item responses, others on test scores. As approaches often do not produce consistent results, previous research has created the impression that approaches to instructional sensitivity…

Traditionally, teachers evaluate students' abilities via their total test scores. Recently, cognitive diagnostic models (CDMs) have begun to provide information about the presence or absence of students' skills or misconceptions. Nevertheless, CDMs are typically applied to tests with multiple-choice (MC) items, which provide less diagnostic…

The present study examines an ecological model for intervention use to explain student vocabulary performance in a multi-tiered intervention setting. A teacher self-report measure composed of factors hypothesized to influence intervention use at multiple levels (i.e., individual, intervention, and system level) was administered to 54 teachers and…

The approach of information digitalization era has largely changed the teaching environment on campus. The application of information technology to education has become a concern in modern education.Traditional basic literacy of reading, writing, and algorithm could no longer cope with the demands in information societies that the information…
