Scientific models and modeling play an important role in science, and students' understanding of scientific models is essential for their understanding of scientific concepts. The measurement instrument of "Students' Understanding of Models in Science" (SUMS), developed by Treagust, Chittleborough & Mamiala ("International…

Direct observation recording procedures produce reductive summary measurements of an underlying stream of behavior. Previous methodological studies of these recording procedures have employed simulation methods for generating random behavior streams, many of which amount to special cases of a statistical model known as the alternating renewal…

The research on the assessment of collaborative problem solving (ColPS), as one crucial 21st Century Skill, is still in its beginnings. Using Tangible User Interfaces (TUI) for this purpose has only been marginally investigated in technology-based assessment. Our first empirical studies focused on light-weight performance measurements, usability,…

Knowledge elicitation from human beings is important for many fields, such as decision support systems, risk communication, and customer preference studying. Traditional approaches include observations, questionnaires, structured and semi-structured interviews, and group discussions. Many publications have been studying different techniques for a…

The study was conducted to know the effect of items direction (positive or negative) on the factorial construction and criterion related validity in Likert scale. The descriptive survey research method was used for the study and the sample consisted of 510 undergraduate students selected by used random sampling technique. A scale developed by…

Randomized controlled trials (RCTs) are increasingly used to evaluate programs and interventions in order to inform education policy and practice. High quality reports of these RCTs are needed for interested readers to understand the rigor of the study, the interventions tested, and the context in which the evaluation took place (Mayo-Wilson et…

Proof is a central concept in mathematics education, yet mathematics educators have failed to reach a consensus on how proof should be conceptualized. I advocate defining proof as a clustered concept, in the sense of Lakoff (1987). I contend that this offers a better account of mathematicians' practice with respect to proof than previous accounts…

This paper explores the role examples play in mathematicians' conjecturing activity. While previous research has examined example-related activity during the act of proving, little is known about how examples arise during the formulation of conjectures. Thirteen mathematicians were interviewed as they explored tasks that required the development…

Predictive validity was explored between vocabulary matching (VM) probe scores and the "integrated" Louisiana Education Assessment Program (iLEAP) social studies standardized subtest score for 224 sixth-grade students across demographic categories from one rural southeastern Louisiana school district. Multiple Linear Regression (MLR)…

Purpose: This policy brief discusses validity and fairness issues that could arise when test-based information is used for making "high stakes" decisions at an individual level, such as, for the certification of teachers or other professionals, or when admitting students into higher education programs and colleges, or for making…

This paper examines the utilization of construct validity in formative assessment for classroom-based purposes. Construct validity pertains to the notion that interpretations are made by educators who analyze test scores during formative assessment. The purpose of this paper is to note the challenges that educators face when interpreting these…

The 1999 "Standards for Educational and Psychological Testing" defines validity as the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests. Although quite explicit, there are ways in which this definition lacks precision, consistency, and clarity. The history of validity has taught us…

Purpose: To develop a suitable mobility course for the assessment of mobility performance as part of a user evaluation of Electronic Mobility Aids (EMA) aimed at obstacle detection and orientation. Method: A review of the literature led to a list of critical factors for the assessment of mobility performance of persons who are visually impaired.…

This study examined the psychometric characteristics and construct validity of the Icelandic form of the Career Adapt-Abilities Scale (CAAS-Iceland). The CAAS consists of four scales that measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. The…

This article reports on the development and validation of the Distance from Privilege (DFP) measures. Items for the measures were developed on theoretical grounds. The primary sample consisted of 292 undergraduates with various majors from a Midwestern University and a Historically Black University in the south. One of the measures is the…
