This paper presents a new approach to science education that takes a path through sociocultural theory and into the ideas of Gloria Anzaldúa. We apply Anzaldúan theory to science education by illustrating it in action through various examples which explore the multidimensionality of teaching science with Latin@ students in various contexts including dual language settings. We present what it is to journey through transformation using examples from educators at various levels of science within the world of teaching science with Latin@ students in the U.S. Our examples illustrate how Latin@ students cross many cultural borders in Spanish, English, Latin@ home culture, school culture, and the world of scientific dialogue and content, and in doing so, go through tensions and transformations between dominant and non-dominant worlds, which should be acknowledged and better understood through Anzaldúan theory. Fundamentally, we present a transformative notion of Latin@ science learning as “living on the bridges” of many dialogic and cultural practices, and having to negotiate these in-between spaces, or “nepantla” (Anzaldu´a and Keating in Interviews, Psychology Press, London, 2000), where Latin@ students must contend with the fragmented and sometimes painful struggle of living in racialized reality amidst the demands of a dominant culture, and where transformation and healing are possible through the path of conocimiento. We advocate for teachers to become science teacher nepantler@s, who guide their students through nepantla, and into a new mestiz@ consciousness of science education. 相似文献

The social processes involved in engaging small groups of 3–15 managers in their sharing, organising, acquiring, creating and using knowledge can be supported with software and facilitator assistance. This paper introduces three such systems that we have used as facilitators to support groups of managers in their social process of decision-making by managing knowledge during face-to-face meetings. The systems include Compendium, Group Explorer (with Decision Explorer) and V*I*S*A. We review these systems for group knowledge management where the aim is for better decision-making, and discuss the principles of deploying each in a group meeting. 相似文献

Can engaging college students in client-centered projects in science, technology, engineering, and mathematics (STEM) coursework increase interest in STEM professions? The current study explored the effectiveness of project-based learning (PjBL) courses on student attitudes, major choice, and career aspirations in STEM. Framed in expectancy-value and social cognitive career choice models, we examined the effect of engaging in at least one authentic, project-based course during the first four semesters of college on student STEM attitudes and career aspirations in a quasi-experimental study with a sample of (N = 492) natural science and engineering students. STEM self-efficacy and subjective task value variables (STEM attainment, intrinsic and utility value of STEM courses, and relative cost associated with engaging in STEM courses) were examined as mediators of the relationship between classroom project-based experiences and STEM career aspirations. Gender and underrepresented minority status were also examined. We found that engaging in at least one project-based course during the first four semesters affected student perceptions of STEM skills, perceptions of the utility value of participating in STEM courses, and STEM career aspirations. Furthermore, we found that the effect of project-based courses on STEM career aspirations was mediated by STEM skills and perceptions of course utility. The effect of PjBL was not moderated by race or gender. We highlight areas of future research and the promise of PjBL for engaging students in STEM professions. 相似文献

The BIO2010 report recommended that students in the life sciences receive a more rigorous education in mathematics and physical sciences. The University of Delaware approached this problem by (1) developing a bio-calculus section of a standard calculus course, (2) embedding quantitative activities into existing biology courses, and (3) creating a new interdisciplinary major, quantitative biology, designed for students interested in solving complex biological problems using advanced mathematical approaches. To develop the bio-calculus sections, the Department of Mathematical Sciences revised its three-semester calculus sequence to include differential equations in the first semester and, rather than using examples traditionally drawn from application domains that are most relevant to engineers, drew models and examples heavily from the life sciences. The curriculum of the B.S. degree in Quantitative Biology was designed to provide students with a solid foundation in biology, chemistry, and mathematics, with an emphasis on preparation for research careers in life sciences. Students in the program take core courses from biology, chemistry, and physics, though mathematics, as the cornerstone of all quantitative sciences, is given particular prominence. Seminars and a capstone course stress how the interplay of mathematics and biology can be used to explain complex biological systems. To initiate these academic changes required the identification of barriers and the implementation of solutions. 相似文献

It is widely acknowledged in the literature on philosophy of biology and, more recently, among biologists themselves that the gene concept is currently in crisis. This crisis concerns the so-called “classical molecular concept”, according to which a gene is a DNA segment encoding one functional product, which can be either a RNA molecule or a polypeptide. In this paper, we first describe three categories of anomalies that challenge this way of understanding genes. Then, we discuss proposals for revising the gene concept so as to accommodate the increasingly known complexity of genomic architecture and dynamics. Our intention is to provide an informative overview of recent proposals concerning how we should conceive of genes, which are probably not very familiar to many science educators and teachers, but can bring relevant contributions to genetics teaching, in particular, to a more critical treatment of genes and their role in living systems. 相似文献

Knowledge assets have become relevant to every organization and society since they are the most valuable product and production means in the knowledge economy. But measuring intangible assets still remains a challenge. The emerging knowledge-based view is still far from being a widely accepted theory. Researchers in this field are faced with knowledge-based value dynamics, changing environments and uncertainty. Knowledge assets are embedded capabilities in individuals, organizations or societies. This research is focused on the design of artifacts that enhance Intelligence Capital. Intelligence, understood in a comprehensive manner, is a knowledge asset that leverages adaptive capabilities through information gathering, sense-making and adaptation. From this approach, developing Intelligence Capital means to increase adaptive capabilities to make better decisions supported on internal and external knowledge. The purpose of this research is to apply the Intelligence Capital framework to a Technology Development Centre at the Tecnologico de Monterrey. It is expected that through this intervention, Intelligence Capital capabilities of this Centre can be assessed and managed. This model is an innovating proposal that deals with Capital Systems, adaptive capabilities and complexity. 相似文献

ABSTRACTThe different technology fields have increased in complexity, especially during the last two decades, giving place to the concept of Complex Technology. An example is Electronics also characterised as a horizontal technology being incorporated in many products and processes of other technological areas. Bloom’s taxonomy of learning objectives and the revised version of Bloom disciples, which have been used by several experts in pedagogy, suffers from a generalist character and are not adapted to technology learning. In this article an engineering learning taxonomy is presented. Also a computer learning assisted tool called ISETL (Integrated System for Electronics Technology Learning) has been developed to facilitate the Electronics fundamentals understanding. ISETL has been evaluated taking into account not only the results of the theoretical assessments but also through the results obtained in the laboratory. These results demonstrate the advantages of this approach and can be depicted by the progressive improvements registered in student performance. 相似文献

Relevant events in the history of twentieth-century zoological collection in Cuba and the institutions involved are traced here in order to document the present whereabouts of Cuba's zoological collections. The historical accounts are divided into two periods: from the founding of the republic in 1902 to the revolutionary victory of 1959, and from 1959 to the present. A preliminary survey of the nature, size, and current state of these collections is included. 相似文献
