Argues that the candle-and-cylinder demonstration does not show that air is composed of 21% oxygen. Finds that the heating of air results in a partial expulsion of air, and that the flame is extinguished by a local, rather than a complete, consumption of oxygen. (WRM)

Investigates the reasons for data fabrication among undergraduate and graduate students. Presents several examples of getting misled by the candle and tumbler demonstration. Concludes that presented facts, concepts, or principles increase the incidence of data cooking. (YDS)

The experimental/analogy group scored significantly higher than the control group on a posttest question that required the definition of diffusion (n=77 community college students). Hypothetico-deductive reasoning skill was significantly related to correct application of the diffusion concept to a change from the misapplication of the polarity and…

Reports on a study in which clinical interviews were conducted with three elementary school children to determine the extent to which they held naive misconceptions about important biological topics, and to determine agewise trends in the development of biological knowledge. (TW)

Explores the relationships between seventh-grade students' misconceptions of genetics and natural selection and four cognitive variables: reasoning ability; mental capacity; verbal intelligence; and cognitive style. Reports that only the reasoning ability was significantly related to the number of misconceptions. (Author/YP)

Discussed is learning theory as it is related to the teaching of biology. This article proposes that extension of the original cycle model into three types of learning cycles can form the basis of a satisfactory and educationally practical model of instruction. Includes 30 references. (CW)

This paper describes how the learning cycle leads students to become more skilled reasoners. The three phases of the learning cycle are described and examples and goals of each are provided. Information is also offered on the three types of learning cycles: the descriptive; the empirical-inductive; and the hypothetical-deductive. Each is described…

This review covers approximately 300 studies, including journal articles, dissertations, and papers presented at conferences. The studies are organized under these major headings: status surveys; scientific reasoning; elementary school science (student achievement, student conceptions/misconceptions, student curiosity/attitudes, teaching methods,…

This monograph describes the origins of the learning cycle, related research, and how future research might be conducted to further the understanding of theories of instruction. A wide range of information is synthesized, producing a coherent framework for better understanding the theory of the learning cycle. The monograph identifies various…
