The "Framework" and NGSS bring to the forefront the role of language in doing science and in learning from doing science. Yet, most existing science assessments for elementary learners do not integrate or attend to aspects of scientific language and literacy that are essential components of science proficiency. Accordingly, there is a…

Background: Fair comparisons of educational systems in large-scale assessments can be made only if the differences in curricula have little impact on the outcomes. This study investigated the sensitivity of science achievement rankings to varying degrees of curriculum implementation in the Trends in International Mathematics and Science Study…

Universities have a long-established tradition of granting students special consideration when circumstances beyond their control negatively affect performance in assessments. Typically, such situations affect only one student (e.g. medical emergencies) but we consider the impact of a natural disaster that led to all students being eligible for…

Anatomy and Physiology at the University of Canberra, Australia, as in many institutions, is taught to large cohorts at the foundational level. There is a requirement for students to not only retain information regarding physiological systems and their associated anatomy, but also the integration and relationship between systems. Furthermore,…

This study examined students' voluntary use of digital self-assessment quizzes as a resource for learning in a large anatomy and physiology lecture course. Students (n = 238) could use 16 chapter quizzes and four analogous unit quizzes to rehearse and self-assess knowledge. Most students (75%) engaged in occasional use of self-assessment quiz…

Giftedness in science today is largely measured by various kinds of standardized tests--IQ tests, SATs, ACTs, GREs, and so forth. For example, many STEM (science, technology, engineering, math) gifted programs rely at least in part on IQ tests or the SAT for identifying students as gifted. It might be useful to supplement such standard measures…

Smoothing techniques are designed to improve the accuracy of equating functions. The main purpose of this study is to compare seven model selection strategies for choosing the smoothing parameter (C) for polynomial loglinear presmoothing and one procedure for model selection in cubic spline postsmoothing for mixed-format pseudo tests under the…

Students with the most significant cognitive disabilities (SCD) are the 1% of the total student population who have a disability or multiple disabilities that significantly impact intellectual functioning and adaptive behaviors and who require individualized instruction and substantial supports. Historically, these students have received little…

Anatomical relationships are challenging concepts for first-year medical students. The use of progressive drawing, where an image is created from a blank template, has long been utilized for outlining anatomical relationships and continuity from one region to another, and has shown positive outcomes for student learning. More recently,…

The NRC (2012) Framework and the ensuing Next Generation Science Standards (NGSS) have brought crucial shifts in the goals for students' science learning. Teachers bear the responsibility of translating the three-dimensional vision of student learning articulated in these documents in classrooms through instruction. Central to the idea of…

Since 2013, 39 states and the District of Columbia have adopted the Next Generation Science Standards (NGSS) or similar standards based on the National Research Council's "A Framework for K-12 Science Education," signaling a commitment to high-quality and rigorous science education for all students. States' previous science standards…

From a sociocognitive perspective, item parameters in a test represent regularities in examinees' item responses. These regularities are originated from shared experiences among individuals in interacting with their environment. Theories explaining the relationship between culture and cognition also acknowledge these shared experiences as the…

Large-scale assessments (LSAs) use Mislevy's "plausible value" (PV) approach to relate student proficiency to noncognitive variables administered in a background questionnaire. This method requires background variables to be completely observed, a requirement that is seldom fulfilled. In this article, we evaluate and compare the…

International large-scale assessments (ILSAs) have become an important part of the Swedish evaluation system. It is therefore of crucial importance to validate national measures of Swedish students' achievement with their ILSA test scores. Here, we offer results from such a validation study based on Swedish students' test scores in IEA's Trends in…

As we move further into the digital age, the acquisition of digital literacy (DL) and computational thinking (CT) skills is emerging internationally as an essential goal for students in contemporary school curricula. As the world becomes more uncertain and volatile due to impacts of artificial intelligence (AI), international unrest, climate…
