Detection of metal ions in solution has been performed without employing H[subscript 2]S or any other sulfide materials. The new method is free from the interference from anions. Identification of Na[superscript +], K[superscript +], and NH[subscript 4][superscript +] has been made possible directly from an aqueous extract of the sample mixture. A…

The leaders of Networks for School Improvement (NSIs) have complex, challenging jobs which require constant learning and adaptation. To support these leaders, the contributors to this volume have developed a survey-based data visualization system--the Improvement Network Health Development (INHD) Information System--designed to generate insight…

This article discusses the author's belief that if assessment is going to have an impact, it must be woven into the larger tapestry that tells the tale of a student experience that leads to student and institutional success. Included are considerations for how to design meaningful ways to measure movement on the things that people care about.

Spatial skills can predict mathematics performance, with many researchers investigating how and why these skills are related. However, a literature review on spatial ability revealed a multiplicity of spatial taxonomies and analytical frameworks that lack convergence, presenting a confusing terrain for researchers to navigate. We expose two…

In this Point of Departure, the idea of authentic assessment is examined and troubled by drawing on Derrida's hauntology. The spectres of higher education invite us to reconsider what is 'real' about past, present, and future assessment practices. Such spectres do not lecture or produce a single, definitive interpretation. Rather, these spectres…

The author provides information about reliability and areas that educators should examine in determining if an assessment is consistent and trustworthy for use, and how it should be interpreted in making decisions about students. Reliability areas that are discussed in the column include internal consistency, test-retest or stability, inter-scorer…

Narratives that dominant the discourse of the experiences of people of color, specifically in education settings, are incomplete. Therefore, identifying methodological approaches that emphasize the perspectives of minoritized groups is essential. Counternarratives have been applied to help (re)tell stories of the oppressed to challenge dominant…

Students' talent and potential cannot be served until they are recognized by schools or caregivers. While the field of gifted education has had success in identifying many students with talents in reading and mathematics, those with spatial talents are often overlooked. This article reviews how we might identify spatial talent using traditional…

Popular item response theory (IRT) models are considered complex, mainly due to the inclusion of a random factor variable (latent variable). The random factor variable represents the incidental parameter problem since the number of parameters increases when including data of new persons. Therefore, IRT models require a specific estimation method…

Social cognition is a very important group of neurocognitive processes involved especially in social functioning; currently, the amount of research on this topic is increasing and suggests some considerations about its assessment, particularly in the child population. This article presents some of these considerations focussed on the theoretical…

As an educator, and a student myself, I believe that the current system of graded assessments used ubiquitously in education systems worldwide is quite flawed. Although certain issues arise in its implementation, a suitable alternative might be to consider gradeless assessments. Thus, rather than completely advocating for a change in the way…

To provide practice and assessment of computational thinking, we need specific problems students can solve. There are many such problems, but they are hard to find. Learning environments and assessments often use only specific types of problems and thus do not cover computational thinking in its whole scope. We provide an extensive catalog of…

Classroom-based assessment (CBA) takes place in learning environments influenced by myriad individual and contextual factors. Nevertheless, factors related to individual differences and learner psychology are seldom considered in creating instructional environments designed to facilitate learners' use of CBA. This article introduces the concept of…

This paper will highlight the work at Delaware State University, an HBCU, on experiential education projects through a Howard Hughes Medical Institute (HHMI) Inclusive Excellence grant. It focuses on assessing experiential learning curriculum in individual courses as well as evaluating student growth from research and external opportunities. It…

Assessment holds the key to unlocking for the teacher a child's past (what he already knows), present (what he is learning), and future (what he still needs to learn) to inform teaching. Despite the benefits of assessment for informing teaching practice and enhancing student learning, it remains one of the most challenging and time-consuming tasks…
