A 3D model visualization and basic molecular modeling laboratory suitable for first-year undergraduates studying introductory medicinal chemistry is presented. The 2 h practical is embedded within a series of lectures on drug design, target-drug interactions, enzymes, receptors, nucleic acids, and basic pharmacokinetics. Serving as a teaching aid…

What are the boundaries between traditional and new media, between ability and disability, and between the artist and the processes for making art? This article reports findings from a study of tablet devices as media for self-expression and visual storytelling by adults with intellectual disabilities and examined whether or not art-making…

In this account of practice I would like to share my experiences of facilitating a Critical Reflection Action Learning (CRAL) set with a small family run business, struggling to make change and expand their services due to the problems they encountered in separating their business lives from their family lives. The account I present here is based…

The main concern of the present study was to compare Iranian monolingual and bilingual EFL students' listening comprehension in terms of Latinized Persian subtitling of English movie to see whether there was a significant difference between monolinguals and bilinguals on immediate linguistic comprehension of the movie. Latinized Persian subtitling…

Education policy in the United States centers K-12 assessment efforts primarily on standardized tests. However, such tests may not provide an accurate and reliable representation of what students understand about the complexity of science. Research indicates that students tend to pass science tests, even if they do not understand the concepts…

Prior studies indicate that vocational students' literacy practices are more demanding than is generally recognised. Employing a view of literacy acquisition as socialisation, we investigated the literacy practices of trades training in Carpentry and Automotive Technology, by interviewing tutors and examined course books and student writing. A…

Acid-base equilibrium is one of the most important and most challenging topics in a typical general chemistry course. This article introduces an alternative to the algebraic approach generally used in textbooks, the graphical log "C" method. Log "C" diagrams provide conceptual insight into the behavior of aqueous acid-base systems and allow…

In this study, we analyzed the correlations between hip flexion power, sprint performance, lumbar lordosis (LL) and the cross-sectional area (CSA) of the psoas muscle (PM). Ten young adults performed two sprint tests and isokinetic tests to determine hip flexion power. Magnetic resonance imaging was used to determine LL and PM CSA. There were…

Two studies investigated the effectiveness of dynamic and static visualizations for a perceptual learning task (locomotion pattern classification). In Study 1, seventy-five students viewed either dynamic, static-sequential, or static-simultaneous visualizations. For tasks of intermediate difficulty, dynamic visualizations led to better…

Good public speaking style requires, among other skills, "effective management of the resources of language." Good speakers choose language carefully to create credibility, emotional impact, and logical appeal. If a speaker's language is wishy-washy, dull, vague, or long-winded, the speaker appears less trustworthy. Audience distrust of a speaker…

In this article, I describe an animated slideshow of Southern blotting that I have made freely available to other instructors. My hope is to provide a clear visualization of the logistics behind the technique so that instructors have a solid basis--as well as time freed up--to discuss its applications with students.

The Venn diagram is suggested as a graphical solution to conjunction fallacies and a modification of it is suggested to more fully communicate set relations.

The enormous progress in the fields of microsystem technology, microelectronics and computer science has led to the development of powerful high speed cameras. Recently a number of such cameras became available as low cost consumer products which can also be used for the teaching of physics. The technology of high speed cameras is discussed,…

Previous studies have found that preschoolers are confused about the relationship between two-dimensional (2D) symbols and their referents. Preschoolers report that 2D images (e.g. televised images and photographs) share some of the characteristics of the objects they are representing. A novel Comparison Task was created to test what might account…

Purpose: To improve lingual ultrasound imaging with the Corrected High Frame Rate Anchored Ultrasound with Software Alignment (CHAUSA; Miller, 2008) method. Method: A production study of the IsiXhosa alveolar click is presented. Articulatory-to-acoustic alignment is demonstrated using a Tri-Modal 3-ms pulse generator. Images from 2 simultaneous…
