Educational media offer no unique benefits. Once research considers lesson content, instructional strategies, and overall resource allocation, student outcome differences will disappear. The multimedia "panacea" is no equalizer, as accessibility problems abound. Schools should invest in cheaper, less fashionable instructional strategies (field…

Using principal-components analysis, this paper highlights the nature of the alleged gap between new and older universities in the United Kingdom, as portrayed in recently published league tables. Although the tables may capture some recognized differences, they rank performance by limited criteria that favor the old university sector and fail to…

Measures both teaching efficacy and the holding of specific alternative conceptions of preservice elementary teachers (N=619). Uses a survey to determine the relationship between teaching efficacy and certain alternative conceptions. Contains 77 references. (DDR)

Discusses the basic features and goals of environmental education incorporated into curricula in Slovenia. Findings suggest that waste-processing products are not well known and that Slovene children should be taught about environmental problems that are part of everyday life. (DDR)

Examines the myth that Mexican American children have poor academic achievement because their parents don't value education. Focuses on the myth's origins in "deficit thinking" and concepts of "cultural deprivation" and "at-risk." Examines evidence to the contrary: Mexican Americans' long struggle for equal…

Asks whether what is taught in science class only makes sense to someone who already understands science. Discusses school science in terms of four questions: (1) What is to be taught?; (2) What conditions promote learning?; (3) What do students learn?; and (4) What are the cognitive processes in learners' minds? (Contains 17 references.)…

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…
