This experimental investigation seeks to corroborate a knowledge structure sorting task approach as a measure to more fully account for prior knowledge when reading. A latent semantic analysis (LSA) network derived from thousands of texts typically read by first year college students was used to create a prototypical referent network model of the…

Purpose: The aims of this study were to classify, identify and follow-up young swimmers' performance and its biomechanical determinants during two competitive seasons (in seven different moments of assessment--M), and analyze the individual variations of each swimmer. Method: Thirty young swimmers (14 boys: 12.70 ± 0.63 years-old; 16 girls:…

The heterogeneity among children with learning disabilities still represents a barrier and a challenge in their conceptualization. Although a dimensional approach has been gaining support, the categorical approach is still the most adopted, as in the recent fifth edition of the "Diagnostic and Statistical Manual of Mental Disorders." The…

Given the wide range of ability (academic, linguistic and cultural) in classrooms differentiated instruction is often difficult to manage. District and building level leadership can play an important role by providing the vision and support needed to implement Whole School Cluster Grouping (WSCG), the innovative scheduling approach described in…

With the recent rise in popularity of social network sites, more and more personal information is becoming available online. Since a person's information is generally available in various formats across multiple sites, there are ever increasing interests in consolidating such personal information from multiple information sources. The goal of…

This study identifies clusters of U.S. and Canadian metropolitan areas with similar knowledge traits. These groups--ranging from Making Regions, characterized by knowledge about manufacturing, to Thinking Regions, noted for knowledge about the arts, humanities, information technology, and commerce--can be used by analysts and policymakers for the…

This study involved the investigation of the effects of the Total Cluster Grouping Model on the achievement and identification of urban, elementary students and to learn about the classroom practices of and perceptions classroom teachers had of their students' ability levels over the course of the study. Proportionality of representation in…

In educational research, a fundamental goal is identifying which skills students have mastered, which skills they have not, and which skills they are in the process of mastering. As the number of examinees, items, and skills increases, the estimation of even simple cognitive diagnosis models becomes difficult. We adopt a faster, simpler approach:…

Purpose: This study provides a comprehensive examination of substitutions that occur at Greenlee's 3rd stage of cluster development (M. Greenlee, 1974). At this stage of cluster acquisition, children are able to produce the correct number of consonants but with 1 or more of these consonants being substituted for another. Method: Participants were…

This article argues the need for, and provides, a dichotomous single access key for the identification of common British wild flower families. A minimum of technical vocabulary is used while at the same time retaining most of the recent botanical names of families. The key provides a user-friendly opportunity for school pupils to become familiar…

This study (a) provided a conceptual introduction to differential item functioning (DIF), (b) introduced the multifaceted Rasch rating scale model (MRSM) and an associated statistical procedure for identifying DIF in rating scale items, and (c) applied this procedure to previously collected data from American coaches who responded to the coaching…
