Rethinking the Role of Information Technology-Based Research Tools in Students’ Development of Scientific Literacy

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.     

The nature of scientific knowledge and student learning: Two longitudinal case studies

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.     

Risk factors for infant maltreatment: a population-based study

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.     

Parent-Child Relationships, Family Problem-Solving Behavior, and Sibling Relationship Quality: The Moderating Role of Sibling Temperaments

In this study we sought to determine whether sibling temperaments moderated the associations of parent-child relationship quality and family problem-solving behavior with sibling relationship quality. Observational assessments of mother-child and father-child relationship quality, family problem-solving behavior, and sibling relationship quality were obtained from the families of 49 pairs of brothers and 46 pairs of sisters. Mean ages were 10-2 for older siblings and 7-6 for younger siblings. Parent-reported child temperament assessments were also obtained. The links among mother–older child relationship quality, father–older child relationship quality, and sibling relationship quality were moderated by the older sibling's temperament. The younger and older siblings' temperaments moderated the associations between the quality of the father–younger sibling and sibling relationships. The association between family problem-solving behavior and sibling relationship quality was not moderated by sibling temperaments.     

Editorial Power/Authorial Suffering

In this article, I analyse the publish or perish enterprise and in particular the origins of editorial power/knowledge. My actor-network analysis shows how tenure, promotion, and salary decisions apparently unrelated to editorial decisions are important elements that accrue power/knowledge to editors of particular journals. What my actor-network analysis does not show, and which I therefore analyse from a subject-centred perspective, is the other side of editorial power/knowledge: authorial suffering. I suggest that the structure of our science education discipline necessitates a particular commitment to the responsibilities and obligations of editors and reviewers to the authors, particularly the newcomers, and therefore to the production and reproduction of science education.
