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.

At the risk of seeming to make exaggerated claims for visual methodologies, what I set out to do is lay bare some of the key elements of working with the visual as a set of methodologies and practices. In particular, I address educational research in South Africa at a time when questions of the social responsibility of the academic researcher…

The purpose of this practice brief is to provide schools, districts, and states with background knowledge about best practices for older students who struggle to read. It focuses on the reading skills that adolescents need to more fully access content-area curricula and, in turn, secure a productive future. The authors define adolescent reading as…

Poland subscribes to an abstinence-only model of reproductive health education called "Education for Life in the Family." The aim of this study was to determine if the perceptions of adolescent mothers could be used to improve delivery of the Polish model of education. This study was conducted using focus group interviews with fourteen…

This article presents the findings from classroom based research into the use of SMART Boards (interactive whiteboards) with kindergarten children. SMART Boards have been used successfully over the past 8 years at Abbotsleigh Junior School as innovative ways to enhance teaching and learning and facilitate assessment in primary Science. Key…

This study employs the Excel function to design dynamic visual activities for factors and multiples word problem learning. A teaching experiment was carried out eight times in 4 weeks on three fifth grade students. The result showed that after using multiple-linked representations activities, students made greater progress in understanding target…

In the mathematics education literature, there is currently a debate about the mechanisms by which group discussion can contribute to mathematical learning and under what conditions this learning is likely to occur. In this paper, we contribute to this debate by illustrating three learning opportunities that group discussions can create. In…

This article reports that several colleges and universities like Purdue University are mining data they have about students to try to improve retention. The institutions analyze years' worth of data on which students did well and which did poorly, and what variables--whether they be SAT scores, financial-aid status, or attendance at the dining…

The purpose of the study was to examine the ecologies of two teachers and the extent that each teacher's agenda aligned with instructional activities and assessments for each unit of instruction. Data were collected in four ways: (1) videotaped record of each lesson, (2) live observation field notes and expanded field notes from the videotape, (3)…

Practice posters, with pictures and captions, are useful for controlled practice of vocabulary and structures in an EFL context. The author has found many advantages of using posters with beginners in a high school setting. Student led review gets students active, increases autonomy and improves confidence. The use of small groups is effective…

Graphical User Interfaces (GUIs) are pervasive elements of most modern technical software and represent a convenient tool for student instruction. For example, GUIs are used for [chemical] process design software (e.g., CHEMCAD, PRO/II and ASPEN) typically encountered in the senior capstone course. Drag and drop aspects of GUIs are challenging for…
