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…

The product Bayes factor (PBF) synthesizes evidence for an informative hypothesis across heterogeneous replication studies. It can be used when fixed- or random effects meta-analysis fall short. For example, when effect sizes are incomparable and cannot be pooled, or when studies diverge significantly in the populations, study designs, and…

Responding to recent challenges to Clay's Running Records (2019) and their analysis using a three-cueing system, the author examines this reading assessment from an additive perspective of both bottom-up and top-down orientations of reading instruction. Endorsing their inclusion among classroom reading assessments, the author navigates the tension…

Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

In the age of fake news, teachers in every subject area should redouble their efforts to help students distinguish between credible and deceptive sources of information. The author calls attention to a few key resources, including the CRAAP guidelines developed at California State University, Chico, and promoted by the American Library Association.

As teachers are increasingly asked to respond to assessment and evaluation demands in their schools, the aim of this article is to provide suggestions and scales for singing accuracy. A description of each step in the assessment design process is provided, along with specific suggestions for a singing development scale and a singing accuracy scale.

Effective instructor evaluation is complex and requires the use of multiple measures--formal and informal, traditional and authentic--as part of a balanced evaluation system. The student voice, a critical element of that balanced system, is appropriately complemented by instructor self-assessment and the reasoned judgments of other relevant…

This paper reviews current known issues in student self-assessment (SSA) and identifies five topics that need further research: (1) SSA typologies, (2) accuracy, (3) role of expertise, (4) SSA and teacher/curricular expectations, and (5) effects of SSA for different students. Five SSA typologies were identified showing that there are different…

Precision is a key facet of test development, with score reliability determined primarily according to the types of error one wants to approximate and demonstrate. This article identifies and discusses several primary forms of reliability estimation: internal consistency (i.e., split-half, KR-20, a), test-retest, alternate forms, interscorer, and…

Numerous professionals have written about the need for investigations at the heart of learning to engage and inspire, and to maximize impact upon learning. This article asks if children can use tablets to record their investigations while they are still "in the thick" of them, and also provide valuable assessment data? "In the thick…

Massive Open Online Courses (MOOCs) are becoming an increasingly popular choice for education but, to reach their full extent, they require the resolution of new issues like assessing students at scale. A feasible approach to tackle this problem is peer assessment, in which students also play the role of assessor for assignments submitted by…

The high rate of students taking developmental education courses suggests that many students graduate from high school unready to meet college expectations. A college readiness screener can help colleges and school districts better identify students who are not ready for college credit courses. The primary audience for this guide is leaders and…

Context: Musculoskeletal palpation is taught in our athletic training programs as part of the injury evaluation process. However, as palpation skills are taught, the focus is oftentimes on accuracy of surface-anatomy landmarks instead of the ability to discriminate qualitative information such as tissue tone, spasm, or pain response from the soft…

Diagnostic tools can help schools more consistently and fairly match instructional resources to the needs of their students. To ensure the best educational outcome for each child, diagnostic decision-making systems seek to balance time, clarity, and accuracy. However, recent research notes that many educational decisions tend to be made using…

This paper aims to translate for practitioners the principles and methods for evaluating screening measures in education, including benchmark goals and cut points, from our technical manuscript "Evaluation of Diagnostic Systems: The Selection of Students at Risk of Academic Difficulties" (this issue). We offer a brief description of…
