From professional lives to inclusive practice: Science teachers and scientists' views of gender and ethnicity in science education

To provide insight into issues of gender and ethnicity in science education, we examine the views of approximately 60 secondary science teachers and university scientists from three different research projects. In each project, participants and researcher explored the intersection of professional and personal identities; views of the nature of science; beliefs related to students' experiences in science education; and kinds of curricular and instructional strategies used to promote access and equity for all students. Participants' interviews were analyzed qualitatively for patterns across these four dimensions of inclusive science education. Analysis of data revealed a wide range of beliefs and experiences along each dimension. From our findings, we argue for careful examination of the ways identities shape instructors' professional experiences and educational practices; critical, constructive conversations about feminist science studies scholarship between professional developers and science teachers or scientists; and reasoned reflection on how views of students can inform recommendations for inclusive content and instruction. We conclude with the call for increased sophistication in the conceptualization and implementation of solutions to the “problem” of women and ethnic minorities in science education, for balancing recognition of systematic gender and ethnic bias with sensitivity to instructors and students' diverse interests and experiences. © 2000 John Wiley & Sons, Inc.

Sociology of science as a means to a more authentic,inclusive science education

In this article, we argue that insights from scholarship in the sociology of science can provide a powerful basis for making science education more authentic and inclusive. Drawing on recent work in the sociology of science, we describe how adopting sociological ideas as integral components of science curricula and instruction can provide opportunities for students that a traditional approach cannot. We focus on three insights from sociology—social networking, peer review, and skepticism—to demonstrate how sociological understandings can inform and improve the content, structure, and pedagogy of science classrooms. We argue that shifts in the balance of power and authority that result from explicit attention to these aspects of the nature of science offer a more authentic science education for all. © 1998 John Wiley & Sons, Inc.

Childhood adversity, educational trajectories, and self-reported health in later life among U.S. women and men at the turn of the century

A major objective of current life course research is to specify the processes linking early childhood conditions to subsequent life course statuses that span educational, occupational, familial, and health domains across the life span. This study confronts at least two persistent challenges to the rigorous specification of the relationships among these variables. The first is that the point-in-time measurement of education as “years of schooling” masks considerable heterogeneity in the timing and curricular tracks of schooling and obscures our understanding of how and when education matters for life-course inequality. The second challenge involves interdependencies between aspects of life-course inequality, including educational achievement and health. The intertwining of these variables across the life course, and their usual conceptualization and measurement, limit the interpretation of their relationship and its generalizability across studies. We use data from three waves of the National Survey of Families and Households between 1987–1988 and 2001–2002 to explore trajectories of self-reported health, applying latent class cluster analysis (finite mixture models) to deal directly with these measurement and specification issues. Generally, we find mediating effects of education in mid- to late-life health demonstrating the pivotal role of education in life course processes. Women’s childhood backgrounds are more heterogeneous and temporally complex educational careers affect their self-assessed health more than men’s. Late degrees are linked to poor health trajectories among women, but not men. Also, marital history, number of births and health behaviors are associated in expected ways with women’s and men’s health trajectories at midlife.     

The Political Consequences of Ambivalence: The Case of Democratic Reform in Hong Kong

Recent research has shown that attitudinal ambivalence has importantimplications on political attitudes and behavior. The conceptholds one of the keys to understanding complicated and seeminglycontradictory opinions of the public. This article examinesambivalence in public opinion regarding democratic reform inHong Kong. Analysis of a representative survey (N = 600) showsthat common citizens indeed have a significant degree of ambivalencetoward the government's political reform bill proposed in 2005.Regarding consequences, objective ambivalence is shown to havegreater predictive power than subjective ambivalence. The formerrelates negatively to attitude extremity and weakens the attitude–behaviorlinkage. However, contrary to the usual finding in the literature,objective ambivalence also relates positively to protest participationintention. The theoretical and social implications of the findingsare discussed. Received for publication June 29, 2007. Accepted for publication October 8, 2008.     

Investigating the quality of the school technology needs assessment (STNA) 3.0: A validity and reliability study

Schools and districts should use a well-designed needs assessment to inform important decisions about a range of technology program areas. Presently, there is a lack of valid and reliable instruments available and accessible to schools to effectively assess their educational needs to better design and evaluate their projects and initiatives. The School Technology Needs Assessment (STNA) is a free, user-friendly online survey tool that meets this need for planning and formative evaluation of technology projects in educational settings. This study used existing data from a robust sample (n = 1918) of educators from across North Carolina to examine the reliability and validity of STNA. A collective review of study results including the literature review, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and internal consistently reliability analysis indicated that STNA was a high-quality instrument.     

The role of socioeconomic status and school quality in the Philippines: Revisiting the Heyneman–Loxley effect

In 1983, Heyneman and Loxley stated that in low income countries, school-level factors could account for a greater proportion of variance in student achievement as compared to student-level characteristics. The phenomenon has come to be known as the “HL effect” and signaled the important role of schools in developing countries. This study investigated the presence of the HL effect using a longitudinal sample of 1790 11.5-year-old students from 60 schools in a developing country, the Philippines. The main variables of interest were related to socioeconomic status and proxy measures of school quality. The correlates of achievement were explored using two-level multilevel modeling, while controlling for students’ prior ability. While findings did not support the presence of the HL effect in the sample, with schools accounting for only 3–5% of overall conditional variance, schools were found to be important in the production of higher achievement scores.     

Identity formation of teacher–mentors: An analysis of contrasting experiences using a Wengerian matrix framework

In order to understand the process of identity formation in a community of practice, Wenger (2002) proposes a matrix framework whereby three qualities (connectedness, expansiveness and effectiveness) are matched against three modes of belonging (engagement, imagination and alignment). In this paper we use this framework to analyse the experiences of two teacher–mentors and interpret how their identities are formed during the process of mentoring student–teachers. Factors that contribute significantly to the development of their identity include the school culture, the ‘personalities’ of the other community members, and the influence of other relevant communities of practice.     

Getting ‘virtual’ wrongs right

Whilst some philosophical progress has been made on the ethical evaluation of playing video games, the exact subject matter of this enquiry remains surprisingly opaque. ‘Virtual murder’, simulation, representation and more are found in a literature yet to settle into a tested and cohesive terminology. Querying the language of the virtual in particular, I suggest that it is at once inexplicit and laden with presuppositions potentially liable to hinder anyone aiming to construct general philosophical claims about an ethics of gameplay, for whom assumptions about the existence of ‘virtual’ counterparts to morally salient phenomena may prove untrustworthy. Ambiguously straddling the pictorial and the performative aspects of video gaming, the virtual leaves obscure the ways in which we become involved in gameplay, and particularly the natures of our intentions and attitudes whilst grappling with a game; furthermore, it remains unclear how we are to generalise across encounters with the virtual. I conclude by briefly noting one potential avenue of further enquiry into our modes of participation in games: into the differences which a moral examination of playfulness might make to ethical evaluation.     

Rotation,Translation, and Trajectory in Diving

Abstract

Theories causing rotation of the body in diving were critically reviewed and a statement relating angular momentum to both the angle of lean and the angle of force was presented. Equations were developed by which the partition of energy between rotation and translation could be computed.
