Because of concerns about test security, different test forms are typically used across different testing occasions. As a result, equating is necessary in order to get scores from the different test forms that can be used interchangeably. In order to assure the quality of equating, multiple equating methods are often examined. Various equity…

When engaged in conversation, both parents and children tend to re-use words that their partner has just said. This study explored whether proportions of maternal and/or child utterances that overlapped in content with what their partner had just said contributed to growth in mean length of utterance (MLU), developmental sentence score, and…

Background: People with aphasia (PWA) use pantomime, gesture in absence of speech, differently from non-brain-damaged people (NBDP). Aims: To evaluate through an exploratory study the comprehensibility of PWA's pantomimes and to find out whether they can compensate for information PWA are unable to convey in speech. Methods & Procedures: A…

We examined the association between autistic traits and sexual orientation in a general adult population (N = 47,356). Autistic traits were measured with the ten items Autistic Quotient questionnaire using a cut-off score of = 6. Sexual orientation was assessed by self-report. Multinomial logistic regression was used to estimate odds ratios (ORs)…

This study compared the effects of two types of delayed feedback (correct response or correct response + rationale) provided to students by a computer-based testing system following an exam. The preclinical medical curriculum at the University of Kansas Medical Center uses a two-exam system for summative assessments in which students test, revisit…

The psychometric properties of a new multidimensional measure of test anxiety, the Test Anxiety Measure for College Students (TAM-C), based on theory and current research were examined in a sample of 312 Canadian college students online. The TAM-C consists of a Facilitating Anxiety scale and five test anxiety (Cognitive Interference, Physiological…

Approximately, 283 sixth-grade students completed four randomly generated Math Curriculum-Based Measures (M-CBMs) from interventioncentral.org twice during a fall semester. These M-CBMs measured foundational skills in addition, subtraction, multiplication, and division. We found that using mean fluency or accuracy scores from four M-CBMs produced…

In this article we propose a framework for reporting mathematics results from national assessment surveys (NAS) such that effective use of the resulting reports can enhance teaching and learning. We explored literature on factors that may contribute to non-utilisation of assessment data as a basis for decision-making. In the context of South…

With the intent of amending the 21-item BDI-II to improve its reliability and validity when administering the scale to nonclinical populations, a survey package consisting of 19 positive items with semantically reflected response options to mirror the negative scenario options in the original BDI-II (excluding items 16 and 18) was created. These…

Test administrators are appropriately concerned about the potential for time constraints to impact the validity of score interpretations; psychometric efforts to evaluate the impact of speededness date back more than half a century. The widespread move to computerized test delivery has led to the development of new approaches to evaluating how…

Purpose: This work explores the clinical relevance of three measures of morpheme use for preschool-age Spanish-English bilingual children with varying language skills. The 3 measures reflect accuracy, diversity (the tense marker total), and productivity (the tense and agreement productivity score [TAP score]) of the English tense and agreement…

Policymakers have grown increasingly interested in how experimental results may generalize to a larger population. However, recently developed propensity score-based methods are limited by small sample sizes, where the experimental study is generalized to a population that is at least 20 times larger. This is particularly problematic for methods…

Creative reasoning and problem-solving are crucial to how scientists work and how students learn in school science. However, developing guided inquiry that develops these capabilities within a prescriptive curriculum has proven difficult. In this paper, we report on a study of a teaching sequence that aimed to develop these capabilities through…

Teacher education programs are under considerable pressure to evaluate their effectiveness in training new teachers. Over the last several decades there have been repeated calls for more systematic research on preservice teacher preparation programs. One institution has heeded this call, using the Video Assessment of Interactions and Learning…

Purpose: Instructional tasks are a form of content knowledge that can be defined as specialized content knowledge (SCK). We examined the changes in the use of instructional tasks and SCK index scores of preservice teachers from methods to final practicum. Method: Five preservice teachers were observed through the methods practicum where they…
