Some innovations in the images of cells and molecules that keep changing for new techniques and as a result of using new approaches to old methods are explored and new ways of illustrating cell and molecular structures are discussed. The three elements that play an important role in any biological image are aesthetic factors such as picture style…

A two-minute overhead demonstration using a molecular model kit is employed for illustrating the unique binding of cyclopropane. It is reported that most model kits, much like an sp (super 3) hybridized carbon atom, resist forming 60-degree bond angles.

An illustration of how excess Gibbs energies of the components in binary systems can be used to construct boiling point diagrams is given. The underlying causes of the various types of behavior of the systems in terms of intermolecular forces and the method of calculating the coexisting liquid and vapor compositions in boiling point diagrams with…

Children with learning and behavior problems often have difficulty getting through their day, to a great extent because they have difficulty organizing themselves and understanding the organization of the environment around them. Neurotypical children and adults organize themselves in many ways by using calendars, planners, lists, and so forth.…

Food preparation skills are needed to prepare low-cost, nutritious meals that meet current dietary recommendations. Research indicates that many youth and adults can read a recipe for ingredients, but they often do not know basic food preparation techniques such as how to broil, fold, dredge, baste and other cooking methods. To address the need to…

We present and discuss three examples of misapplication of the notion of conditional probability. In each example, we present the problem along with a published and/or well-known incorrect--but seemingly plausible--solution. We then give a careful treatment of the correct solution, in large part to show how careful application of basic probability…

Students analyze a photograph to solve mathematical questions related to the images captured in the photograph.

A series of single-subject experiments were conducted to evaluate the effects of presentational, translational, illustrative, instructional, and summarizing supports on the reading and listening comprehension of students with moderate intellectual disabilities. The specific eText supports under investigation included digitized voice and…

This case study discusses a collaborative three year project involving two school clusters located in the North Island and South Island of New Zealand. The project was named "Project ACTIVate" and its main thrust was to study how the use of the interactive whiteboard (IWB) combined with teaching, learning and research across schools. The…

This paper presents a model--"hypertextual function"--to consider teachers' thinking, practice, and development in the use of technology. Hypertextual function is a multi-dimensional model linking a teacher's knowledge about students ("familiarity") and technology ("facility"), with a teacher's teaching practice of integrating technology with…

This article describes ways in which digital imagery can be used to enhance mathematics instruction. (Contains 6 figures.)

This article explores the use of ironic performance in education, particularly around issues of human rights. I examine my own efforts to engage audiences with the history of domestic espionage and sabotage by the intelligence agencies of the United States. This is a history well known to some marginalized counterpublics (see Fraser, 1997), but…

Purpose: The purpose of this paper is to outline a three-stage process for engaging with students to develop school level indicators of health in sequential class groups students first generated, then categorised indicators and finally developed schematic representations of their analyses. There is a political and practical need to develop…

In our Fundamentals of Genetics lab, students perform a wide variety of labs to reinforce and extend the topics covered in lecture. I developed an active-learning lab to augment the lecture topic of mutagenesis. In this lab exercise, students determine if a compound they bring from home is a mutagen. Students are required to read extensive…

The reading and literacy focus of a unit that centers on chocolate can provide a context for using the interpretive mode of the communication standard from the "National Standards in Foreign Language Education." This article presents a thematic unit that is applicable to all languages and adaptable to any level. Inspired by Woodlands'…
