Vision II school science is often stated to be a democratic and inclusive form of science education. But what characterizes
the subject who fits into the Vision II school science? Who is the desirable student and who is constructed as ill-fitting?
This article explores discourses that structure the Vision II science classroom, and how different students construct their
identities inside these discourses. In the article we consider school science as an order of discourses which restricts and
enables what is possible to think and say and what subject-positions those are available and non-available. The results show
that students’ talk about a SSI about body and health is constituted by several discourses. We have analyzed how school science
discourse, body discourse and general school discourse are structuring the discussions. But these discourses are used in different
ways depending on how the students construct their identities in relation to available subject positions, which are dependent
on how students at the same time are “doing” gender and social class. As an example, middle class girls show resistance against
SSI-work since the practice is threatening their identity as “successful students”. This article uses a sociopolitical perspective
in its discussions on inclusion and exclusion in the practice of Vision II. It raises critical issues about the inherited
complexity of SSI with meetings and/or collisions between discourses. Even if the empirical results from this qualitative
study are situated in specific cultural contexts, they contribute with new questions to ask concerning SSI and Vision II school
science. 相似文献

In the United States today, urban schools serve the majority of high-poverty and high minority populations including large
numbers of Hispanic students. While many Hispanic students perform below grade level in middle school science, the science
teaching community as a whole is lacking elements of diversity as teachers struggle to meet the needs of all learners. Researchers
have recognized that science teacher effectiveness, one consequence of self-efficacy among teachers, is associated with future
science achievement and science-related careers of their students. This qualitative study explores how three science teachers’
effectiveness in the classroom impacts students’ science self-efficacy beliefs at one urban middle school. Hispanic students
were the focus of this investigation due to demographics and history of underperformance within this district. Teachers’ perspectives,
as well as outside observer evaluations of instructional strategies and classroom climates were triangulated to explore dynamics
that influence students’ interests and motivation to learn science using a framework to link teachers’ sense of efficacy (focusing
on student outcomes). Findings suggest the impact teacher effectiveness can have on student outcomes, including strengthened
student science self-efficacy and increased science achievement. Building awareness and support in teachers’ sense of efficacy,
as well as developing respectful and supportive relationships between educator/facilitator and pupil during the transition
to middle school may construct permanence and accomplishment for all in science. 相似文献

This paper focuses on the role of dominant school discourses in structuring how students position themselves and others relative
to a community centered on science. The study was conducted in a diverse, eighth grade classroom in an urban magnet school.
I argue that dominant discourses portray a limited view of available subject positions, in that the purpose of learning science
is associated with a dichotomous view of people as being either college-bound or not. I explore how these limited subject
positions can pose contradictions with some students’ interests, constrain students’ visions of possibilities, exacerbate
disadvantages based on race and class, and interfere with students acquiring identities as science learners. However, there
are also possibilities for resistance, agency and self-definition through students’ talk.

Previous research on science education has described various factors influencing students’ participation and produced categorizations
of students based on e.g. cultural background. In this article it is argued, theoretically and empirically, that an understanding
of students’ participation in science education needs to begin with an analysis of what activity students are engaged in.
The aim is to explore how altering conditions of classroom work may open up opportunities for students mainly participating
in an activity of education or schooling to engage in an activity of science learning. Activity is conceptualized in a Cultural-Historical
Activity Theory perspective as object-oriented and transformative. Drawing on an ethnographic study in a Swedish compulsory
school, a critical incident of the participation in science education of a 7th grade girl called Helena is analyzed. The results
show that altered conditions of classroom practice may produce new possibilities for student participation, and point to the
impossibility of determining students as ‘different kinds of students’ based on a priori categories e.g. sex, ethnicity, socio-economic
background. 相似文献

The article builds upon a study where students’ relations to science are related to their worldviews and the kind of worldviews
they associate with science. The aim of the study is to deepen our knowledge of how worldview and students’ ways to handle
conflicts between their own worldview and the worldview they associate with science, can add to our understanding of students’
relations to science. Data consists of students’ responses to a questionnaire (N = 47) and to interviews (N = 26). The study shows that for students who have a high ability in science, those who have taken science-intense programmes
in upper secondary school to a higher extent than others have worldviews in accordance with the worldviews they associate
with science. This indicates that students who embrace a worldview different from the one they associate with science tend
to exclude themselves from science/technology programmes in Swedish upper secondary school. In the article the results are
presented through case studies of single individuals. Those students’ reasoning is related to the results for the whole student
group. Implications for science teaching and for further research are discussed. 相似文献

This study examined standard 6 and 8 (Standards 6 and 8 are the sixth and eighth years, respectively, of primary level schooling
in Kenya.) students’ perceptions of how they use mathematics and science outside the classroom in an attempt to learn more
about students’ everyday mathematics and science practice. The knowledge of students’ everyday mathematics and science practice
may assist teachers in helping students be more powerful mathematically and scientifically both in doing mathematics and science
in school and out of school. Thirty-six students at an urban school and a rural school in Kenya were interviewed before and
after keeping a log for a week where they recorded their everyday mathematics and science usage. Through the interviews and
log sheets, we found that the mathematics that these students perceived they used outside the classroom could be classified
as 1 of the 6 activities that Bishop (Educ Stud Math 19:179–191, 1988) has called the 6 fundamental mathematical activities and was also connected to their perception of whether they learned
mathematics outside school. Five categories of students’ perceptions of their out-of-school science usage emerged from the
data, and we found that 4 of our codes coincided with 2 activities identified by Lederman & Lederman (Sci Child 43(2):53,
2005) as part of the nature of science and 2 of Bishop’s categories. We found that the science these students perceived that they
used was connected to their views of what science is. 相似文献

Components of Conceptual Ecologies 总被引：1，自引：0，他引：1
Hyun Ju Park 《Research in Science Education》2007,37(2):217-237
The theory of conceptual change is criticized because it focuses only on supposed underlying logical structures and rational
process processes, and lacks attention to affective aspects as well as motivational constructs in students’ learning science.
This is a vast underestimation of the complexity and diversity of one’s change of conceptions. The notion of conceptual ecology
provides a context for understanding individuals’ conceptual change learning, as it is the environment through which all information
is interpreted. This research investigated how high school students’ statements, made in answering questions, reflect selected
components of their conceptual ecologies. Data for this study was collected from six interviews in which seven students took
part. The data also include the science teacher’s profiles of each student, the students’ personal journals, their assignments,
and their examinations and answers in class. The analysis presented will here include only those components that were represented
in the discourse of the seven high school students who were interviewed. When students were asked questions, there was evidence
of the engagement of the various components of conceptual ecologies. These components include: epistemological commitments,
metaphysical beliefs, the affective domain and emotional aspects, the nature of knowledge, the nature of learning, the nature
of conceptions, and past experience. Evidence from this study suggests that these components might function as constraints
to learning. This study contributes to the field by expanding our knowledge of the components of high school students’ conceptual
ecologies through its definition of the categories and themes associated with those components. In examining across the range
of components, the study illustrates the variety and sources of science conceptions within high school students’ conceptual
ecologies. 相似文献

Recent research has to a limited extent explored the characteristics of students’ conceptual practices as sociocultural phenomena
in general and in science education in particular. I approach this issue by studying a group of students while solving a particular
scientific problem from A to Z, and as part of this analyse how different cultural means (the knowledge domain and the tools
in use) structure the students’ interactions and how their interpersonal relations change over this period of time. The aim
is to illustrate how these cultural means intersect in productive and less productive ways during the students’ conceptual
practices. The study has its point of departure in a design experiment where a group of four students, together with their
teacher, solve different problems related to the biological phenomenon of sequencing a DNA molecule (the insulin gene). Video-recordings
of the students’ interactions constitute the basis for this analysis. The cultural means strongly structure the students’
conceptual practices during their problem solving processes. Whereas the knowledge domain structured the whole process, the
significant roles of the website and the computer-based 3D model of the insulin gene were especially apparent during the second
part of the trajectory. The intersection of these cultural means appear productive in terms of disciplinary knowledge when
the students’ became aware of how to handle this relationship. The interpersonal relations between the students and their
teacher altered slightly in the beginning and became increasingly more fixed during the students’ progression. 相似文献

The Australian Government’s policy to transform higher education by 2020 includes plans to significantly raise the levels
of undergraduate enrolment by people of low socio-economic status. In light of this policy direction, this article examines
how a group of undergraduate students of low socio-economic status work to maintain their desire for learning and to remain
included in the university system despite experiencing cultural processes of exclusion. As the students reflect on the cultural
and pedagogical conditions that promote, support and enhance their participation and engagement in higher education, a picture
emerges of the importance of students’ relationships with academics. Whilst positive relationships help students to remain
engaged, negative experiences work against continuing participation and engagement. Given the desire of the Australian government
to increase participation in higher education by students from under-represented groups, this research identifies some challenges
and possibilities for both universities and academics. 相似文献

This position paper proposes the enhancement of teacher and student learning in science classrooms by tapping the enormous
potential of information communication and technologies (ICTs) as cognitive tools for engaging students in scientific inquiry.
This paper serves to challenge teacher-held assumptions about students learning science ‘from technology’ with a framework
and examples of students learning science ‘with technology’. Whereas a high percentage of students are finding their way in
using ICTs outside of school, for the most part they currently are not doing so inside of school in ways that they find meaningful
and relevant to their lives. Instead, the pedagogical approaches that are most often experienced are out-of-step with how
students use ICTs outside of schools and are not supportive of learning framed by constructivism. Here we describe a theoretical
and pedagogical foundation for better connecting the two worlds of students’ lives: life in school and life outside of school.
This position paper is in response to the changing landscape of students’ lives. The position is transformative in nature
because it proposes the use of cyber-enabled resources for cultivating and leveraging students new literacy skills by learning
‘with technology’ to enhance science learning. 相似文献

This article sets out to examine how school science activities can encourage students’ participation while supporting a specific
science content. One ordinary class with 12-year-old students was chosen and their regular classroom work was studied without
intervention and with a minimum of interference. Lessons were video filmed, transcribed and analyzed focussing on the participants’
speech acts. It was found that students’ initiatives and experiences were important parts of their participation. The results
show how students’ participation was orchestrated with a science content by means of four different kinds of activities. The
activities are called ‘individual inventory of experiences’, ‘building a common platform of experiences’, ‘sharing new experiences’
and ‘concluding a common platform’. The activities form a foundation for participation in human biology topics. For example,
to ‘build a common platform of experiences’ seems to level out students’ different prerequisites for participating in subsequent
tasks. Furthermore, to ‘conclude a common platform’ implied a checkpoint of the shared new experiences. The activities support
students’ tentative use of scientific words as well as their learning of what counts as knowledge in the school science setting.
However, it can be questioned if the time spent on each separate activity is necessary or if similar achievements could be
made even if some activities were integrated. The question is open for further research.

This paper reports and discusses the principal findings of an Australian study exploring the decisions of high achieving Year 10 students about taking physics and chemistry courses (Lyons, 2003). The study used a ‘multiple worlds’ framework to explore the diverse background characteristics that previous quantitative research had shown were implicated in these decisions. Based on analyses of questionnaire and interview data, the study found that the students’ decisions involved the complex negotiation of a number of cultural characteristics within their school science and family worlds. Many of the students regarded junior high school science as irrelevant, uninteresting and difficult, leaving them with few intrinsic reasons for enrolling in senior science courses. The study found that decisions about taking physical science courses were associated with the resources of cultural and social capital within their families, and the degree to which these resources were congruent with the advantages of choosing these courses. The paper concludes that the low intrinsic value of school science and the erosion of its strategic value contribute to the reluctance of students to choose physical science courses in the senior school. 相似文献

The aim of the reported study was to explore how science teachers made sense of their roles and responsibilities in teaching
and assessing science coursework. The focus was on the teacher assessment, the feedback that teachers gave to students and,
how they perceived their role when they taught and assessed students’ science coursework reports. The research methodology
included observation of science lessons, collection of marked students’ reports and two interviews with each of the nine participant
teachers. Two cases of teachers are considered as representative of the participant teachers and their perceptions and practices
are compared and contrasted. Teachers either adopted the role of the examiner or combined the role of the teacher with that
of examiner. They distinguished marking of science theory exercises from marking of coursework and, teaching theory from teaching
investigations, on the basis that the grade they assigned to coursework contributed to the total grade for external exams.
A key conclusion is that teaching and assessment of science coursework need to re-focus on learning. The study calls for changes
in public policy for summative assessment to place more reliance on teachers’ assessments and secondly, for changes in school
practices in formative assessment for teachers to support students to learn in the case of science coursework. 相似文献

This study investigated students’ perceptions of the generalist learning environment of the primary school compared to their
perceptions of the specialist science learning environment of secondary school. The role of student gender and change in school
size as influencing factors on changes in students’ perceptions across primary to secondary transition were especially considered.
The same students’ perceptions of the learning environment were collected in the final stages of primary school and again
after their initial term in secondary school. Insights were gained into how students’ perceptions of learning environment
changed during their first exposure to specialised science learning environments and teachers, and how these changes in perceptions
during transition depended upon school size and student gender. Both school size and student gender were found to be influencing
factors for changes in some learning environment dimension perceptions. 相似文献

Students’ interest in studying science and their aspirations to pursue science-related careers is a topic of global concern.
In this paper, a set of data gathered for the initial phase of the 5-year study of Science Aspirations and Careers: Age 10–14
(the ASPIRES project) is presented. In the initial phase of this project, a questionnaire exploring students’ aspirations
was developed, validated and trialled with nearly 300 primary school students. Principal component analyses and Cronbach’s
alpha revealed that the questionnaire was comprised of a number of unidimensional components and that reliability was acceptable.
Further multivariate analyses indicated that students’ aspirations in science were most strongly predicted by parental attitudes
to science, attitudes towards school science, self-concept in science, images of scientists and engagement in science-related
activities outside of school. Moreover, ‘Asian’ students appeared to exhibit a highly positive set of attitudes towards science
and aspirations in science, particularly when compared with White students. Reasons for this observed difference are also
explored. 相似文献

This study investigates how the enactment of a climate change curriculum supports students’ development of critical science
agency, which includes students developing deep understandings of science concepts and the ability to take action at the individual
and community levels. We examined the impact of a four to six week urban ecology curriculum on students from three different
urban high schools in the USA. Data collection included pre and posttest written assessments from all students (n = 75) and pre and post interviews from focal students (n = 22) to examine how students’ conceptual understandings, beliefs and environmental actions changed. Our analyses showed
that at the beginning of the curriculum, the majority of students believed that climate change was occurring; yet, they had
limited conceptual understandings about climate change and were engaged in limited environmental actions. By the end of the
curriculum, students had a significant increase in their understanding of climate change and the majority of students reported
they were now engaged in actions to limit their personal impact on climate change. These findings suggest that believing a
scientific theory (e.g. climate change) is not sufficient for critical science agency; rather, conceptual understandings and
understandings of personal actions impact students’ choices. We recommend that future climate change curriculum focus on supporting
students’ development of critical science agency by addressing common student misconceptions and by focusing on how students’
actions can have significant impacts on the environment. 相似文献

Examining role forces and resources available to new teachers is crucial to understanding how teachers use and expand cultural,
social, and symbolic resources and how they engage teaching for social justice and caring in urban science education. This
critical narrative inquiry explores three levels of story. First, the narratives explore my role as a district science staff
developer and my efforts to leverage district resources to improve students’ opportunities to learn science. Second, the narratives
explore the ways in which a novice science teacher, Tina, navigated role forces and the aesthetic|authentic caring dialectic
in a high poverty, urban school. A third level of narrative draws on sociological theories of human interaction to explore
role forces and how they shaped Tina’s developmental trajectory. I describe how Tina expanded cultural, social, and symbolic
resources to enact her teaching role. 相似文献

Advocates of constructivist science recommend that school science begins with children’s own constructions of reality. This
notion of the way in which students’ knowledge of science grows is closely paralleled by recent research on teachers’ knowledge.
This paper draws on case study evidence of teachers’ work to show how two experienced teachers’ attempts to develop alternative
ways of teaching science involved reframing their previous patterns of understanding and practice. Two alternative interpretations
of the case study evidence are offered. One interpretation, which focuses on identifying gaps in the teachers’ knowledge of
science teaching, leads to theconstructivist paradox. The second interpretation explores theconstructivist parallel, an approach which treats the process of teachers’ knowledge growth with the same respect as constructivists treat students’
learning of science. This approach, the authors argue, is not only more epistemologically consistent but also opens up the
possibilities of helping teachers lead students towards a constructivist school science.

This paper is a response to Maria Andree’s paper. Andree tells in the paper how mistakes in practical lessons may be critical
events to change students’ attitudes in regard science. While traditionally mistakes in practical lessons could obligate students
to repeat the experiment in order to get the ‘right result’ in the paper we have a good example how we can use the incident
to potentiate students’ participation. In my response I illustrate how transferable is what Andree speaks about but I put
forward further reflections about the traditions that may act as impediment for students’ participation. I thus suggest that
the critical paradigm should be a component in reflecting about science classroom practices in order to alter the traditions. 相似文献
