Given the central place IT-based research tools take in scientific research, the marginal role such tools currently play in
science curricula is dissatisfying from the perspective of making students scientifically literate. To appropriately frame
the role of IT-based research tools in science curricula, we propose a framework that is developed to understand the use of
tools in human activity, namely cultural-historical activity theory (CHAT). Accordingly, IT-based research tools constitute
central moments of scientific research activity and neither can be seen apart from its objectives, nor can it be considered
apart from the cultural-historical determined forms of activity (praxis) in which human subjects participate. Based on empirical
data involving students participating in research activity, we point out how an appropriate account of IT-based research tools
involves subjects’ use of tools with respect to the objectives of research activity and the contribution to the praxis of
research. We propose to reconceptualize the role of IT-based research tools as contributing to scientific literacy if students
apply these tools with respect to the objectives of the research activity and contribute to praxis of research by evaluating
and modifying the application of these tools. We conclude this paper by sketching the educational implications of this reconceptualized
role of IT-based research tools. 相似文献

This study was designed to investigate the relationship between students' views of the nature of scientific knowledge and
their own learning of physics, and the evolution of this relationship over time. Twenty-three students enrolled in a physics
course that emphasised laboratory work and discussions about the nature of science. Over a 15-month period, an extensive data
base was established including student essays and interviews regarding their views of the nature of science and teaching and
learning of physics. As part of an extensive data generation, students read a book on the epistemology of physics, wrote reflective
essays, and subsequently discussed the epistemology of physics in class. Two intensive case studies are used to illustrate
our understanding of students' views over time. Changes in students' views concerning the nature of scientific knowledge and
of the science teaching and learning process, which were not always complementary, are described with the aid of a model.
The findings of this research have direct relevance to the planning and implementation of science courses in which the development
of understandings of the nature of science is an objective. 相似文献

CONTEXT: Of the approximately 900,000 children who were determined to be victims of abuse or neglect by US child protective services in 2002, the birth-to-3 age group had the highest rate of victimization (1.6%) and children younger than 1 accounted for the largest percentage of victims (9.6%). OBJECTIVE: To identify perinatal and sociodemographic risk factors associated with maltreatment of infants up to 1 year of age. DESIGN AND SETTING: Observational cohort study. PARTICIPANTS: 189,055 children born in 1996 in Florida. MAIN OUTCOME MEASURE: Infant maltreatment, defined as a verified report of abuse, neglect, or threatened harm that occurred between day 3 of life and 1 year. RESULTS: 1,602 children (.85%) of the 1996 birth cohort had verified instances of maltreatment by age 1. Of 15 perinatal and sociodemographic variables studied, 11 were found to be significantly related to infant maltreatment. Five factors had adjusted relative risks (RR) of two or greater: Mother smoked during pregnancy (RR 2.8); more than two siblings (RR 2.7); Medicaid beneficiary (RR 2.1); unmarried marital status (RR 2.0); low birth weight infant (RR 2.0). Infants who had four of these five risk factors had a maltreatment rate seven times higher than the population average. CONCLUSIONS: Data on nearly all risk factors found to be significantly associated with infant maltreatment are available on the birth certificate. Such information can be incorporated into a population-based risk-assessment tool that could identify subpopulations at highest risk for infant maltreatment. Because resources are limited, these groups should be given priority for enrollment in child abuse prevention programs. 相似文献

A zoo outreach program led to placing animals in classrooms where those animals became foci for numerous learning activities such as writing, observing, and care. Systematic debriefings suggested uniqueness to learning outcomes connected to zoo animals. Subsequent analysis of student writing indicated that students responded to situational interest by recording more observations, made use of more science facts, and used more science vocabulary when writing about unique animals (albino hedgehog, legless lizard) than ‘ordinary’ animals (rabbit, dove). The results are interpreted in terms of motivation, creating situational interest, and the familiarity of the schema available to the students. Policy implications are discussed. 相似文献

The study of higher education is a broad field. A recent estimate identified some 19 different disciplines and perspectives. Such range of perspectives raises central questions as to what might constitute the core areas. Whilst recognising that history does not possess a single dominant paradigm, this article suggests that history opens up several avenues not without interest to policy studies in higher education. By providing issues the outcome of which is known, history may serve as a vehicle for testing the validity of contemporary theories developed in higher education policy studies. The article argues that greater attention ought to be paid - and most particularly in studies involving cross national comparisons - to the cultural and historic specificities that permeate the formal dimensions of law, structure and administrative forms. 相似文献
