There is a great need for effective evolution education. This paper reviews some of the evidence that demonstrates that need and analyzes some of the foundational semantic, epistemological, and philosophical issues involved. This analysis is used to provide a functional understanding of the distinction between science and non-science. Special emphasis is placed the scientific meaning of the terms theory, hypothesis, fact, proof, evidence, and truth, focusing on the difference between religious belief and acceptance of a scientific theory. Science is viewed as theologically neutral and as not mutually exclusive from religion. Finally, a number of practical recommendations to the classroom biology teacher are presented.  相似文献   

The pedagogical potential of drawing and writing in a primary science multimodal unit     

Rachel E. Wilson  Leslie U. Bradbury 《International Journal of Science Education》2016,38(17):2621-2641

In consideration of the potential of drawing and writing as assessment and learning tools, we explored how early primary students used these modes to communicate their science understandings. The context for this study was a curricular unit that incorporated multiple modes of representation in both the presentation of information and production of student understanding with a focus on the structure and function of carnivorous plants (CPs). Two science teacher educators and two first-grade teachers in the United States co-planned and co-taught a multimodal science unit on CP structure and function that included multiple representations of Venus flytraps (VFTs): physical specimens, photographs, videos, text, and discussions. Pre- and post-assessment student drawings and writings were statistically compared to note significant changes, and pre- and post-assessment writings were qualitatively analysed to note themes in student ideas. Results indicate that students increased their knowledge of VFT structure and function and synthesised information from multiple modes. While students included more structures of the VFT in their drawings, they were better able to describe the functions of structures in their writings. These results suggest the benefits for student learning and assessment of having early primary students represent their science understandings in multiple modes.  相似文献

Open-field behavior of wild and domestic Norway rats     

Edward O. Price  U. William Huck 《Learning & behavior》1976,4(2):125-130

The open-field behavior of wild and domestic Norway rats was compared in 15-min tests administered over 5 successive days. Wild rats exhibited more ambulation, jumping, grooming, and time inactive than domestic rats and spent more time along the arena wall. Within- and between-trial changes in behavior were generally greater for wild rats. Factor analyses revealed major loadings on factors identified as “locomotor behavior” and “grooming.” Support was obtained for the hypothesis that domestication has raised the threshold for avoidance-escape behavior in response to a novel environment.  相似文献   

Energy storage and retrieval     

A. K. Shukla  P. Vishnu Kamath 《Resonance》1996,1(6):61-68

Harnessing sunlight for the production of electrical energy is an engrossing prospect. The crucial concept underlying the success of solar power stations is energy storage and its retrieval on demand which can be most effectively achieved with storage batteries. This article highlights the chemistry of existing and emerging battery technologies.  相似文献

A study of serum lipid profile part-1: Establishment of normal reference values of serum lipid levels in healthy vegetarian population of Gujarat     

C. I. Jhala  U. V. Shah  T. K. Shah  B. K. Naik  J. D. Dafda 《Indian journal of clinical biochemistry : IJCB》1998,13(1):1-7

Fasting samples of 1329 apparently healthy vegetarian Gujarati population were tested for total cholesterol, triglycerides and three major fractions of lipoproteins, i.e. high density lipoproteins, low density lipoproteins and very low density lipoproteins. All the values showed marked increase with the age. Except for serum triglycerides, values differ in males and females in the age group of above 45 years. Compared to Northern Indian population low density lipoprotein and high density lipoprotein values were higher, but values of triglycerides and very low density lipoproteins were lower. There is no significant difference in total cholesterol values. Compared to Southern Indian population low density lipoprotein and very low density lipoprotein values were higher but values of triglycerides, total cholesterol and high density lipoprotein were lower. All serum lipid values were significantly lower than the Westem population. The range of values for both the sexes is presented for different age groups.  相似文献

Multiple worlds/mismatched meanings: Barriers to minority women engineers     

Pauline W. U. Chinn 《科学教学研究杂志》1999,36(6):621-636

Despite receiving over 55% of U.S. bachelor's degrees in 1996, women earned <19% of engineering degrees. Polynesian and Filipino women compose an almost vanishing percentage of these graduates. Interviews with four minority women who were close to or had recently completed degrees in civil or mechanical engineering reveal issues of class, race, and gender that affect school success in general and science success in particular. They specifically describe how stereotyping can lead to social stratification and unequal academic and occupational expectations. Narratives are interpreted through Butler's sex/gender theories, Bhaba's postcolonial theories of mimicry, Bourdieu's concepts of social capital and habitus, Bakhtin's theory of speech genres, and Stanton‐Salazar's concept of social networks. The results suggest that Grade K–12 educators, especially in elementary grades, need to challenge practices that segregate students into groups that reflect socioeconomic and ethnic status. In addition to content knowledge, teachers need the kind of multicultural preparation that will help them work effectively with diverse students and their families. © 1999 John Wiley & Sons, Inc.

Authentic science experiences as a vehicle for assessing orientation towards science and science careers relative to identity and agency: a response to “learning from the path followed by Brad”     

Pauline W. U. Chinn 《Cultural Studies of Science Education》2009,4(3):639-647

This response draws from the literature on adaptive learning, traditional ecological knowledge, and social–ecological systems to show that Brad’s choice is not a simple decision between traditional ecological knowledge and authentic science. This perspective recognizes knowledge systems as dynamic, cultural and historical activities characterized by diverse worldviews and ways of constructing and legitimizing knowledge. Brad’s decision is seen as an example of adaptive learning, identity development and personal/collective agency oriented to increasing tribal influence in resource management decisions and policies. I will conclude that science literacy for all is not served by a transcendent, universal, Western modern view of science.
