Discusses a study that revealed that science teachers, like their students, are capable of handling positive experimental results but fail to evaluate negative results appropriately. Describes a teaching strategy designed to help teachers develop an understanding of the concept of negative results and to apply the idea to different contexts.…

Four kinds of reputed evidence for semilingualism or limited bilingualism are rejected as spurious or irrelevant. An alternative explanation of school failure among language minority children focuses on the lack of first-language support and the absence of comprehensible instruction in content-area knowledge. Implications for bilingual education…

The purposes of this study were (a) to create and validate a scale measuring beliefs regarding dyslexia, (b) to use the scale to investigate the beliefs of educators regarding dyslexia, and (c) to recommend ways that educators can be better prepared to help students with dyslexia. Participants included university faculty as well as undergraduate…

This study examines Turkish pre-service science teachers' understanding of science concepts and their confidence in its teaching. A total of 299 senior science education major students participated in the study. Data collection instruments included the Science Concepts Test, and the Science Teaching Efficacy Belief Instrument. Although findings of…

Psychology students frequently have misconceptions of basic concepts in operant conditioning. Prior classroom observations revealed that most students defined positive reinforcement as reward and equated negative reinforcement and punishment. Students also labeled positive reinforcement as rewarding good behavior and negative reinforcement as…

Plant tropisms--their directional movement in response to stimuli--are a fundamental concept in plant science and excite students because they are the observable signs of life in plants. Unfortunately, the precollege teaching literature is full of tropism misconceptions. An inexpensive clock clinostat is invaluable for student gravitropism and…

Genetics is a difficult topic as it involves abstract concepts, which are not directly observable. Studies on using simulations to support the learning of genetics have largely been confined to the use of quantitative simulations to replace experimentation. This study describes the use of a new type of simulation built using an iconic modelling…

The social and political climate of sex education over the last two decades has dramatically changed, with parents now being encouraged to work in partnership with professionals. This paper seeks to further the argument that involving parents in their child's sex education does matter and can have an impact on their child's future sexual health.…

In our study, we focused on the conceptual understanding of the concepts and processes presented in the first lectures of an introductory course in cellular biology for biology majors. The study topic we considered was, "the structure of DNA and the functions of nucleotides". One hundred and eighteen students were asked to prepare concept maps…

A common misconception about the nature of art and of aesthetic appreciation is that these activities are essentially a question of "feeling," as if tuning in to the right feeling will automatically lead to a full understanding of the work of art. Another widespread misunderstanding essentially reduces art viewing to a simple question of…

This article discusses the viability of concepts such as complex systems theory, evolutionary theory and chaos theory as metaphors for being able to give a global perspective of one particular school described in a previous article entitled "Leading people in a chaotic world." The article restates and re-explains this one particular case in…

We present a design for a junior level numerical methods course that focuses on a series of five open-ended projects in applied mathematics. These projects were deliberately designed to present many of the ambiguities and complexities that appear any time we use mathematics in the real world, and so they offered the students a variety of possible…

This article introduces systems thinking and identifies its implications for practice-based learning and improvement. The article defines systems, identifies fundamental aspects of systems thinking, and provides strategies for creating more practice-based learning environments in medical contexts. (Contains 1 table.)

This article is a cross-validation of R. G. Tedeschi and L. G. Calhoun's (1996) original study of the development of the Posttraumatic Growth Inventory (PTGI). It describes several psychometric properties of scores on the PTGI in a sample of middle- to old-aged adults with a history of cardiovascular disease. The results did not support the…

This paper will present a Marxist analysis of the current function and role of information and communication technology (ICT) in education, with specific reference to schooling in the UK. Over the past five years the UK government has spent in excess of 2.5bn British Pounds on ICT equipment for schools and in "training" teachers to use…
