The goal of having a robust discovery system is a priority of the libraries the authors serve (both work at the Minnesota State Colleges and Universities). Given the current fiscal situation facing public higher education in their state, the current commercial systems were not affordable for most of their libraries. They decided to implement and…

This article describes an investigation of Buffon's coin problem and related problems with the aid of an applet. The problems are accessible at a variety of grade levels and facilitate making connections between geometry and probability.

More and more, health education specialists are integrating technology into their work. Whereas most are familiar with social media sites like Facebook, Twitter and LinkedIn, one relatively new form of social media, location based services (LBS), may be less familiar. Developed in 2000, LBS are software applications that are accessible from a…

Across the U.S., innovative collaboration practices are happening in the cloud: Sixth-graders participate in literary salons. Fourth-graders mentor kindergarteners. And teachers use virtual Post-it notes to advise students as they create their own television shows. In other words, cloud computing is no longer just used to manage administrative…

This paper continues the collection of experiments that describe the use of cell phones as experimental tools in physics classroom education. We describe a computer-aided determination of the free-fall acceleration "g" using the acoustical Doppler effect. The Doppler shift is a function of the speed of the source. Since a free-falling objects…

The aim of this study is to explore ethical dilemmas in critical incidents and the emerged responses that these incidents elicit. Most teachers try to suppress these incidences because of the unpleasant feelings they evoke. Fifty teachers participated in the study. A three-stage coding process derived from grounded theory was utilized. A taxonomy…

Supplementary methods for the analysis of the Delis-Kaplan Executive Function System (Delis, Kaplan, & Kramer, 2001) are made available, including (a) quantifying the number of abnormally low achievement scores exhibited by an individual and accompanying this with an estimate of the percentage of the normative population expected to exhibit at…

Measurement of nonlinearity in social service research and evaluation relies primarily on spatial analysis and, to a lesser extent, social network analysis. Recent advances in geographic methods and computing power, however, allow for the greater use of simulation methods. These advances now enable evaluators and researchers to simulate complex…

Models for measuring individual response precision have been proposed for binary and graded responses. However, more continuous formats are quite common in personality measurement and are usually analyzed with the linear factor analysis model. This study extends the general Gaussian person-fluctuation model to the continuous-response case and…

An outbox of a quadrilateral is a rectangle such that each vertex of the given quadrilateral lies on one side of the rectangle and different vertices lie on different sides. We first investigate those quadrilaterals whose every outbox is a square. Next, we consider the maximal outboxes of rectangles and those quadrilaterals with perpendicular…

With the advent of technologies that allow lecturers to develop presentations using software such as Microsoft PowerPoint, Apple Keynote, and OpenOffice Impress (referred to generically here as "slideware"), lectures and meetings are beginning to resemble cinematic experiences rather than the text filled transactions that have been the norm for…

The aim of this study was to apply Speech-to-Text Recognition (STR) in an effort to improve learning performance in an online synchronous cyber classroom environment. Students' perceptions and their behavioral intentions toward using STR and the effectiveness of applying STR in synchronous cyber classrooms were also investigated. After the…

This research focuses on the development and implementation of an adaptive learning and grading system with a goal to increase the effectiveness and quality of feedback to students. By utilizing various concepts from established learning theories, the goal of this research is to improve the quantity, quality, and speed of feedback as it pertains…

This dissertation introduces a new multimedia security system for the performance of object recognition and multimedia encryption in security and medical applications. The system embeds an enhancement and multimedia encryption process into the traditional recognition system in order to improve the efficiency and accuracy of object detection and…

Twitter. Facebook. These names stir up feelings, opinions, and experiences in just about everyone. As these services rise in popularity, libraries have begun to use them to reach out to patrons. Some libraries use Twitter but not Facebook. Some use Facebook but not Twitter. Some use both Facebook and Twitter, while others use neither. Yes, the…
