The vertical scales of large-scale achievement tests created by using item response theory (IRT) models are mostly based on cluster (or correlated) educational data in which students usually are clustered in certain groups or settings (classrooms or schools). While such application directly violated assumption of independent sample of person in…

Writing skills are considered essential to lifelong success, yet experts cannot agree on one model or set of traits that distinguishes good writing from poor writing. Instructional strategies in developing student writing at the high school level need to include a means by which students receive immediate, specific feedback that acts as a scaffold…

The means of producing information and the infrastructure for disseminating it are constantly changing. The web mobilizes information in electronic formats, making it easier to copy, modify, remix, and redistribute. This has changed how information is produced, distributed, and used. People are not just consuming information; they are actively…

The ability of interlocking polygonal tiles, like those in the "Polydron Frameworks kit," to flex can give rise to polyhedra whose faces don't quite fit. In this article, the author discusses what happens with polyhedra whose faces don't quite fit. (Contains 2 notes.)

With fancy new software developments and growth in both the richness of content and delivery options for information resources, the Database Marketplace 2010 is a feast for buyers. Unfortunately, institutional budget cuts may force more of a famine mentality--with belt-tightening for most, and only purchases that are life-sustaining being served…

This paper gives results of a study on a Personal Response System (PRS). Three sections of college algebra are compared; one section used PRS and PowerPoint, one used PowerPoint, and one was considered a control. Students were given a pretest and posttest with a retired version of a mathematics ACT test, and all students gained an average of one…

The increase in publications presenting molecular evolutionary analyses and the availability of comparative sequence data through resources such as NCBI's GenBank underscore the necessity of providing undergraduates with hands-on sequence analysis skills in an evolutionary context. This need is particularly acute given that students have been…

Discover how your institution can better manage and increase access to instructional applications and desktops while providing a blended learning environment. Receive practical insight into how academic computing virtualization can be leveraged to enhance education at your institution while lowering Total Cost of Ownership (TCO) and reducing the…

This article will highlight the experiences of two baccalaureate Health Information Administration (HIA) programs in the adoption of the American Health Information Management Association's (AHIMA) e-HIM Virtual Laboratory (Virtual Lab) into the Professional Practice Experience (PPE). Information is provided describing the implementation of the…

The purpose of this research was to assess the degree of viewer interaction capabilities of features found on the education portion of museum websites. A content analysis was completed where features were categorized by learning levels including: narrative (the learner is a passive recipient), interactive (the learner chooses what he/she views),…

In this article, we apply the well-known equations of projectile motion to the case of a fighter pilot ejecting from an aircraft, the aim being to establish under what conditions there is danger of impact with the rear vertical stabilizer. The drag force on the pilot after ejection is assumed to vary as the velocity squared and the aircraft motion…

This paper looks at the process of collaboratively creating and disseminating information resources, such as journals, books, papers, and multimedia resources in higher education. This process has been facilitated and encouraged by two relatively new movements, open-source and, especially, open access. The most definitive expression of the…

Since the advent of PowerPoint and course delivery programs like Blackboard, more instructors in higher education are providing students with outlines of their lectures and expecting students to supplement these with their own notes. Although some have found that instructor-provided notes appear to enhance student learning, others suggest that…

Recent studies have tested the addition of worked examples to tutored problem solving, a more effective instructional approach than the untutored problem solving used in prior worked example research. These studies involved Cognitive Tutors, software designed to support problem solving while minimizing extraneous cognitive load by providing…

In this paper we describe how we fostered learning by modifying an existing course which covered topics relevant to biosciences. This course was offered predominantly to first year undergraduate science, biomedical science and environment students. The students were trained to find reliable scientific information via computer searches, and shown…
