The growing awareness of serious difficulties in the learning of energy issues has produced a great deal of research, most of which is focused on specific conceptual aspects. In our opinion, the difficulties pointed out in the literature are interrelated and connected to other aspects (conceptual "as well as" procedural and axiological), which are…

This paper serves to review previously reported studies on students' misunderstandings about the energy conservation principle (the first law of thermodynamics). Generally, studies in literature highlighted students' misunderstandings about the energy conservation principle stem from preliminaries about energy concept in daily life. Since prior…

Concerns about the importance of variation in statistics education and a lack of research in this topic led to a preliminary study which explored pre-service teachers' ideas in this area. The teachers completed a written questionnaire about variation in sampling and distribution contexts. Responses were categorised in relation to a framework that…

The mass of electromagnetic radiation in a cavity is considered using the correct relativistic approach based on the concept of a scalar mass not dependent on the particle (system) velocity. It is shown that due to the non-additivity of mass in the special theory of relativity the ensemble of chaotically propagating mass-less photons in the cavity…

The opportunities and challenges associated with establishing and sustaining successful chemistry-based technology programs were discussed at Equipping the 2015 Chemical Technology Workforce, a Presidential Event held at the Fall 2006 ACS National Meeting, kicking off an initiative by the same name. The initiative is based on the recent ACS…

Recently, there have been many efforts to use the research techniques developed in the field of physics education research to improve the teaching and learning of quantum mechanics. In particular, part of this research is focusing on misconceptions held by students. For instance, a set of misconceptions is associated with the concept of stationary…

Children have been taught since birth to believe they can do anything they choose, from starring in the school play to mastering long division. All that self-confidence, however, has not produced more capable students. The Brookings Institution 2006 Brown Center Report on Education finds that countries in which families and schools emphasize…

Entropy is that fundamental concept of chemical thermodynamics, which explains the natural tendency of matter and energy in the Universe. The analysis presents the description of entropy, as understood by the Turkish chemistry undergraduates.

This paper reports on the learning of difficult and complex concepts, the characteristics of these concepts that make them difficult for students to learn and understand well, the kinds of misconceptions students acquire, and the difficulty of changing these mistaken beliefs. A scheme, the Conceptual Stability Scheme, is presented for analyzing a…

Although much recent attention has focused on gaps in the achievement of different groups of students, the problem has been with us for decades. This paper presents the problem as one of reducing variation in students' achievement, and reviews the work of renowned educator Benjamin Bloom on this problem. Bloom argued that to reduce variation in…

As follow-up to a previous article "Avoid Misconceptions When Teaching about Plants," the author identifies fifty additional misconceptions. Undergeneralizations are added to the list of oversimplifications, obsolete concepts, terms, misidentifications, and flawed research. A glossary at the end of the article compares words used in botany with…

In a series of studies over the past several years, the authors have examined the extent of psychological misconceptions, their strength, sources, and various factors that may contribute to reducing these, including individual differences. Generally, introductory psychology students come into the course with many popular misconceptions. These…

Examines which of the warrants of authority, coherence, and empirical evidence were invoked by grade 8 science classroom participants in their daily interactions, and whether these were linked to particular teaching referents. Results indicate that when the teacher embraced a context exposure referent at the expense of constructivism, the warrant…

Discusses "impact factor," a measure of journal impact defined by the Institute of Scientific Information (ISI) and available in Journal Citation Reports. Argues that "impact factor" is misnamed and misused, suggesting an alternative name and interpretation of the measure, and proposes two new measures to assess the impact of…

A 1995 survey of 590 children of Nebraska school administrators revealed that the majority of administrators begin their careers when they have small children. Nearly two-thirds of respondents attended the same school where their parents worked. A majority of respondents liked being administrators' children. Teasing bothered many, but being the…
