Surveillance video recording is becoming ubiquitous in daily life for public areas such as supermarkets, banks, and airports. The rate at which surveillance video is being generated has accelerated demand for machine understanding to enable better content-based search capabilities. Analyzing human activity is one of the key tasks to understand and…

We assess whether the organizational culture of traditional public schools shapes their response to competition from charter schools in Arizona, which has a high level of charter school competition. We focus on traditional public elementary schools from 1995 to 1998, when charter schools were introduced in this state. We explore this topic by…

Fieldwork exists as a component of many library schools' curricula. Site supervisors, students, and the schools themselves all play a role. A final part of most fieldwork experiences involves the use of an evaluation form filled out by a site supervisor about the student. In this study, forty seven evaluation forms were collected and analyzed…

Edge-region grouping (ERG) is proposed as a unifying and previously unrecognized class of relational information that influences figure-ground organization and perceived depth across an edge. ERG occurs when the edge between two regions is differentially grouped with one region based on classic principles of similarity grouping. The ERG hypothesis…

Clusterwise linear regression is a multivariate statistical procedure that attempts to cluster objects with the objective of minimizing the sum of the error sums of squares for the within-cluster regression models. In this article, we show that the minimization of this criterion makes no effort to distinguish the error explained by the…

In South Africa, the Grade 12 "classes of 2008 and 2009" were the first to write examinations under the revised Life Sciences (Biology) curriculum which focuses on outcomes-based education (OBE). This paper presents an exploration of what students (as learners) considered to be difficult and interesting in Grades 10-12 Life Sciences…

This research examined teachers' online behaviors while using a digital library service--the Instructional Architect (IA)--through three consecutive studies. In the first two studies, a statistical model called latent class analysis (LCA) was applied to cluster different groups of IA teachers according to their diverse online behaviors. The third…

When it comes to pupils in need of special support and pupils with disabilities, Sweden's compulsory school system is sometimes considered a one-track system. This article analyses and critically discusses current policy and practices at various levels of Sweden's compulsory school system for these pupils. The analysis traces three themes at the…

This study examined the leadership attributes perceived to be possessed by the presidents in South Carolina's Technical College System. The participants consisted of 16 presidents and 80 subordinates that were selected by the presidents. All participants were asked to complete the "Leader Attribute Inventory." Additionally, each…

This study concerns 182 first year mathematics undergraduates' perspectives on the tangent line of function graph in the light of a previous study on Year 12 pupils' perspectives. The aim was the investigation of tangency images that settle after undergraduates' distancing from the notion for a few months and after their participation in…

A. Redish et al. (2007) proposed a reinforcement learning model of context-dependent learning and extinction in conditioning experiments, using the idea of "state classification" to categorize new observations into states. In the current article, the authors propose an interpretation of this idea in terms of normative statistical inference. They…

This article presents findings of research into the quality control (QC) of schools from 2001-2006. In 2001 several targets for QC were set and the progress of 939 primary schools is presented. Furthermore, using cluster analysis, schools are classified into four QC-types that differ in their focus on school (self) evaluation and school…

Constructivist approaches to computer science education emphasize that as well as knowledge, thinking skills and processes are involved in active knowledge construction. K-12 computer science curricula must not be based on fashions and trends, but on contents and processes that are observable in various domains of computer science, that can be…

Purpose/Objectives: The purpose of the study was to assess the food group preferences of second through fifth grade children based on ethnic background, gender, and grade. Food group preferences were determined by the amount of various food groups consumed in meals served as part of the National School Lunch Program at selected schools. Research…

Everyone agrees that a person can not have good education without good teachers, but how do teachers see their profession? Why do people become teachers, what are their frustrations, and what reforms do they think would improve their work? This report is designed to learn more about how to support and retain the most promising teachers. The study…
