More and more teachers create video explanations for their instruction. Whether or not they are effective for learning depends on the videos' instructional quality. Reliable measures to assess the quality of video explanations, however, are still rare, especially for videos created by (preservice) teachers. We developed such a measure in a…

We address the problem of selecting the best of a set of units based on a criterion variable, when its value is recorded for every unit subject to estimation, measurement, or another source of error. The solution is constructed in a decision-theoretical framework, incorporating the consequences (ramifications) of the various kinds of error that…

A method for medical screening is adapted to differential item functioning (DIF). Its essential elements are explicit declarations of the level of DIF that is acceptable and of the loss function that quantifies the consequences of the two kinds of inappropriate classification of an item. Instead of a single level and a single function, sets of…

For a test that consists of dichotomously scored items, several approaches have been reported in the literature for estimating classification consistency and accuracy indices based on a single administration of a test. Classification consistency and accuracy have not been studied much, however, for "complex" assessments--for example,…

Within a response to intervention (RTI) framework, students are typically identified as "academically at-risk" if they score below a specified cut-point on a benchmark screener. Students identified as at-risk are provided with an intervention intended to increase achievement. In the following technical report, we describe a process for…

While measurement precision is relatively easy to establish for single tests and assessments, it is much more difficult to determine for decision making with multiple tests on different subjects. This latter is the situation in the system of final examinations for secondary education in the Netherlands and is used as an example in this paper. This…

Discusses hierarchical text classification for electronic information retrieval and the measures used to evaluate performance. Proposes new performance measures that consist of category similarity measures and distance-based measures that consider the contributions of misclassified documents, and explains a blocking measure that identifies…

Health and social indicators that capture the distinct historical, social, and cultural contexts of Indigenous communities can play an important role in informing the planning and delivery of community interventions. There is currently considerable interest in cataloguing and vetting meaningful community-level health and social indicators that…

Discusses cataloging policy at the University of Alabama libraries that allows the acceptance of LC (Library of Congress) classification call numbers from OCLC cataloging into the local database without shelflisting, and describes a study that measured error rates for locally unshelflisted samples to determine the disarrangement of the local…

Discusses text categorization and Web site classification and proposes a three-step classification system that includes the use of Web pages linked with the home page. Highlights include the k-nearest neighbor (k-NN) approach; improving performance with a feature selection method and a term weighting scheme using HTML tags; and similarity…

Taxometric procedures provide an empirical means of determining which psychiatric disorders are typologically distinct from normal behavioral functioning. Although most disorders reflect extremes along continuously distributed behavioral traits, identifying those that are discrete has important implications for accurate diagnosis, effective…

Presents entirely automatic methods for gathering documents for a hypertext, for linking the set, and for annotating those connections with a description of the type (that is, the nature) of the link. Document linking is based on information retrieval similarity measures with adjustable levels of strictness. Evaluation problems are also…

Discusses scientometric indicators and the strategic value of measurement results using scientometric indicators. Focuses on whether the inclusion of new journals in the "Science Citation Index" can be used for the indication of structural change in the database, and how this change can be compared with reorganizations of relations among…

Discusses levels of the Functional Independence Measure (FIM) as ordinal categories. Presents guidelines developed through the Rasch model that prompt an analyst to investigate whether rating categories produce observations on which meaningful measurement and inference about patient status can be based. (SLD)

This paper sits within the research on the affordances of new technologies in the mathematics classroom and focuses on a specific feature that is available in dynamic geometry environments, i.e. measuring tools, within the context of conjecturing and proving in open geometry problems. We develop a classification of different modalities of…
