Enhancing diversity in science: is teaching science process skills the answer?

The Biology Fellows Program at the University of Washington aims to enhance diversity in science by helping students succeed in the rigorous introductory biology classes and motivating them to engage in undergraduate research. The composite Scholastic Achievement Test scores and high school grade point averages of the Biology Fellows are comparable to those of students who are not in the program; however, they earn, on average, higher grades in introductory biology classes than non-Biology Fellows. Underrepresented minorities and disadvantaged students in the program also earn higher grades in the introductory biology classes than do their non-Biology Fellows counterparts. Analysis of the performance of Biology Fellows shows that the program assists students who are not proficient in certain science process skills and that students who lack these skills are at risk for failing introductory biology. This evaluation provides insight for designing programs that aim to enhance the performance of beginning students of biology, particularly for underrepresented minorities, who want to obtain a life science degree.     

Explaining the expansion of feminist ideas: cultural diffusion or political struggle?

This article explores the expansion of feminist ideas as both a conceptual and a political issue. It focuses on two major theories of social change, world culture theory (WCT) and world system analysis (WSA), comparing and contrasting how they frame gender as a factor shaping society, how they account for the diffusion of feminist ideas and how they assess the impact of gender norms on sociocultural outcomes. Through the examination of texts and research based on these theories, this article weighs the ability of the theories to meaningfully and justly recognise the place of gender politics within the dynamics of social change. Both WCT and WSA predict isomorphism in the way gender is framed in modern society, but their explanatory accounts traverse drastically different paths. One asserts a conflict-free diffusion of values, whereas the other, decidedly based on conflict, sees gender as emerging from resistance or anti-systemic movements. The article concludes with an assessment of the contribution and missing aspects of each theoretical perspective.     

Teaching web site design: science or art?

In this paper we discuss an approach to teaching web site design to higher education (HE) students that attempts to balance the artistic and scientific aspects of the web site design process. The design of IT systems has traditionally been viewed as a technical activity. However, unlike existing types of IT systems, an organization's web site is available to the general public, and as such needs to be designed in a different manner, with far more emphasis on presentation and ease of use than existing types of IT systems. This is necessary since if the web site is not appealing to the user they can simply choose another web site, and potential customers or clients are lost. Hence, students need to be taught how to incorporate both artistic and scientific aspects when designing a web site.     

Students' engagement in a science classroom: Does knowledge diversity matter?

Knowledge diversity describes group members' differences in terms of prior knowledge in a domain. The purpose of the study was to investigate whether knowledge diversity would impact students' engagement in small-group learning in a science classroom. A total of 45 seventh-grade students were recruited to participate in the study in which two experimental conditions were compared: low-prior-knowledge groups (all low-prior-knowledge students) versus mixed knowledge groups (low-prior-knowledge students with one knowledgeable student). Participates were randomly assigned into six low-prior-knowledge groups (24 individuals in total) and five mixed knowledge groups (21 individuals in total). Engagement, as well as group performance, was measured. The results of a series of independent-samples t test demonstrated that the mixed knowledge groups had significantly higher behavioral, emotional, and social engagement and better group performance than did the low-prior-knowledge groups. This implies that even having one knowledgeable student could enhance students' engagement in a science classroom.     

Review:Anticancer effects of Chinese herbal medicine,science or myth?

BACKGROUND OF CHINESE HERBAL MEDI- CINE (CHM) CHM is one branch of traditional Chinese medi- cine (TCM). TCM and western medicine have different ethnic and social backgrounds. The main difference between TCM and western medicine rests how to deal with illness. TCM, focusing on holism and naturalism, combines Chinese medical experi- ence with Chinese culture. In general, Chinese prac- titioners focus on the “yin” and “yang” balance in the body, which is in accordance wi…     

Assessing the Nature of Science: What is the Nature of Our Assessments?

This paper discusses the nature of the instruments used to assess students' and teachers' conceptions of the nature of science during the last four decades. Two salient points emerge from critically reviewing the various research emphases and associated assessment instruments specifically related to the nature of science. The first is to question the validity of much of the research presented on the grounds that (a) assessment instruments are interpreted in a biased manner, and (b) some assessment instruments appear to be poorly constructed. Although such comments are well founded, it is important to note that the research conclusions were unusually uniform regardless of the particular instrument used in an investigation. The second point is a more critical concern about the traditional paper and pencil approach to the assessment of an individual's understanding of the nature of science. Although not a new insight, discrepancies between the interpretation of a written response to a traditional instrument (e.g., multiple choice assessment) and the intent of the respondent have been well documented. It is suggested that the current educational research shift toward more qualitative, open-ended approaches to assessment of individuals' understanding (of any concept) be applied to the assessment of individuals' nature of science conceptions.     

HPS and school science education: remediation or reconstruction?

Concern to incorporate historical and philosophical insights within school science curricula is an international phenomenon. Whatever the intrinsic merits of these insights, it is suggested that any willingness on the part of science educators to enter into a rapprochement with scholars in the history, philosophy and sociology (HPS) of science stems mainly from the perceived shortcomings of contemporary school science curricula. Some of the difficulties of incorporating HPS within school science are reviewed and it is argued that, together with broader questions about the role of science in society, historical, philosophical and sociological insights point towards a radical reappraisal of school science education. The article suggests three ways in which such education might respond to some recent work in the history, philosophy and sociology of science.     

Reading religion in Norwegian textbooks: are individual religions ideas or people?

Different religions are treated in different ways in Norwegian sixth form textbooks. We carried out an exhaustive content analysis of the chapters devoted to individual religions in textbooks for the Religion and Ethics course currently available in Norway, using rigorous indicators to code each word, image and question according to whether they were treated the religion as a set of ideas or a group of people. After adjusting for trends in the different kinds of data (word, image, question), we found that Buddhism and Christianity receive significantly more attention for their ideas than Hinduism, Islam and Judaism, which are treated more as people. This difference cannot be explained by the national syllabus or the particularities of the individual religions. The asymmetry also has implications for the pupils’ academic, moral and pedagogical agency for which teachers play a critical role in compensating.     

Raising awareness of uncertainty: A useful addendum to courses in the history and philosophy of science for science teachers?

A brief consideration of the need for courses in the history and philosophy of science (HPS) for science teachers is followed by the development of a suggested addendum. The rationale accepts the developmental argument that a conscious awareness of personal uncertainty of explanation provides the motor of change needed to involve science teachers in thinking critically about the nature of their subject. Following the technique pioneered in a different context by Acredolo and O'Connor (1991), the addendum is developed as a test procedure fostering the expression of uncertainties in relation to important questions about science. Using questions designed to serve our specific purposes, a form of the test is trialled on a small group of science teachers attending courses in a Graduate Certificate in Science Education, and the results used to stimulate and promote their discussion of some critical matters concerning the nature of science.     

A national hero or a Wily Politician? Students’ ideas about the origins of the nation in Sweden

The topic of this article is how primary school students express ideas about the ‘origins of the nation’. The study is based on texts written by Swedish students aged 12–13 about a historical event well embedded in Swedish national mythology, the rise to power of Swedish ‘founding father’ Gustav Vasa. The analysis is inspired by James V. Wertsch's concept of schematic narrative templates. The main finding of the study is that the students mainly structure their answers along one of two different narrative templates; either a kind of historical master narrative with strong foundations in traditional Swedish history culture, or a more generic story about the founding father as a ruthless or corrupt politician, which is arguably influenced by presentism.     

Whose nature of science?

Science education literature explicitly and implicitly advocates basic tenets (criteria) for “the nature of science.” The purpose of this study was to investigate whether the science education tenets are also held by philosophers of science (those who study purported tenets of science), and furthermore, to reveal possible related philosophical positions underpinning differences in responses among the philosophers. The philosophers of science expressed significant disagreements with the tenets, and different philosophers of science varied on their views about the tenets. In addition, relationships were found among the philosophers' views of the nature of science, their views of philosophy of space, and with their philosophy of science in general. Therefore, the tenets that are advocated as basic criteria for science education's “the nature of science” must be reconsidered so that more accurate criteria may be developed for future nature of science research. © 1997 John Wiley & Sons, Inc.
