This interview with Dr. Hallie Preskill focuses on the organizational change method known as appreciative inquiry (AI), which is described as a process that builds on past successes (and peak experiences) in an effort to design and implement future actions. Preskill takes the philosophy and principles put forth by organizational change AI…

How do teachers use the time at the beginning of class before all the students have arrived? Do they simply ignore the latecomers and proceed with instruction, figuring that those who are late will ask fellow students what they missed? Or do they wait a minute or two before starting, filling the space some other way? In this brief article, the…

Much of the focus in the distance education (DE) literature centers around the learner and learning, almost to the exclusion of the teacher and teaching. Consequently, instructors of DE courses have been left suspended in virtual space. This article focuses on the teachers' position in the DE course content, especially with respect to the type of…

An increasing number of academic institutions are considering changing to Web-based systems to take advantage of efficiencies in the collection of end-of-semester course evaluations. In considering such a change it is important that researchers determine whether it will affect mean evaluation scores and response rates. We undertook this study in a…

In the last decade, the total student enrollment in public schools in the U.S. has increased by only 14%, whereas the number of English learners grew by 70% and is projected to grow even more (U.S. Bureau of Census, 2003). In 2003-2004, the National Clearinghouse for English Language Acquisition and Language Instruction Educational Programs…

The objectives of this study were to generate precise estimates of suicide rates in the military while controlling for factors contributing to rate variability such as demographic differences and classification bias, and to develop a simple methodology for the determination of statistically derived thresholds for detecting significant rate…

The authors conducted a Monte Carlo simulation of 4 test statistics or comparing dependent correlations with no variables in common. Empirical Type 1 error rates and power estimates were determined for K. Pearson and L. N. G. Filon's (1898) z, O. J. Dunn and V. A. Clark's (1969) z, J. H. Steiger's (1980) original modification of Dunn and Clark's…

This paper describes our use of the ADDIE protocol to design and develop an interactive tutorial for students learning molecular symmetry operations and point groups. The tutorial provides a 3-D environment where students can examine molecules, structures, and symmetry elements. Most such tutorials are connected to courses or instructors in…

Internationalization and intercultural education may be contradictory concepts as the former supports globalization of the economy and the latter explains mutual learning and intercultural understanding. Higher education is preparing planners, leaders, managers, administrators, policy-makers and teachers to societies. Are pedagogical approaches of…

It is natural to study astronomy outdoors, but it is not quite as natural to study astronomy during the daytime. This lesson uses the Earth's closest star as a subject of study within the schoolyard. The importance of the rising sun is combined with hands-on inquiry in which students explore the properties of shadows. Students (a) complete a…

Written analyses of cases help the student develop the skills of logical analysis and written communication. However, students often question the reliability of the grades that they receive. In this study, the author used six criteria to evaluate case analysis by two graders who were team teaching a course. Results show that even with…

Many children do not enjoy social studies because they see it as having little, if any, relevance to their lives. That response is attributable primarily to two factors: Dry content and even drier instructional strategies. Teachers know that if material presented to children is not meaningful and relevant to their lives, real learning does not…

In 1925, Williams Jennings Bryan, a former congressman from Nebraska and a former Secretary of State under Woodrow Wilson, spent two agonizing weeks defending his religious faith that cost him his life a month after. Bryan was a prosecutor of high school teacher John Scopes, who had violated Tennessee state law by teaching the theory of evolution.…

In this article, the author discusses how to properly implement a case study. Specifically, he discusses how much information should be put into a case study. The author suggests to clearly know what the goals of a case study are before starting to write it. He states that in most cases, the straightforward approach without contradictions poses…

This case study involves the biochemical analysis of the components of commonly available energy drinks, which many students purchase at fairly high prices. Students research the ingredients in each product and their physiological role in the human body, and then attempt to match what they learn with the product manufacturers' marketing claims.…
