The development of scientifically literate citizens remains an important priority of science education; however, growing evidence of students' disenchantment with school science continues to challenge the realization of this aim. This triangulation mixed methods study investigated the learning experiences of 152 9th grade students as they participated in an online science‐writing project on the socioscientific issue of biosecurity. Students wrote a series of hybridized scientific narratives, or BioStories, that integrate scientific information about biosecurity with narrative storylines. The students completed an online Likert‐style questionnaire, the BioQuiz, which examined selected aspects of their attitudes toward science and science learning, prior to their participation in the project, and upon completion of the writing tasks. Statistical analyses of these results and interview data obtained from participating students suggest that hybridized writing about a socioscientific issue developed more positive attitudes toward science and science learning, particularly in terms of the students' interest and enjoyment. Implications for research and teaching are also discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 878–900, 2011 相似文献

In response to international concerns about scientific literacy and students’ waning interest in school science, this study investigated the effects of a science‐writing project about the socioscientific issue (SSI) of biosecurity on the development of students’ scientific literacy. Students generated two BioStories each that merged scientific information with the narrative storylines in the project. The study was conducted in two phases. In the exploratory phase, a qualitative case study of a sixth‐grade class involving classroom observations and interviews informed the design of the second, confirmatory phase of the study, which was conducted at a different school. This phase involved a mixed methods approach featuring a quasi‐experimental design with two classes of Australian middle school students (i.e., sixth grade, 11 years of age, n = 55). The results support the argument that writing the sequence of stories helped the students become more familiar with biosecurity issues, develop a deeper understanding of related biological concepts, and improve their interest in science. On the basis of these findings, teachers should be encouraged to engage their students in the practice of writing about SSI in a way that integrates scientific information into narrative storylines. Extending the practice to older students and exploring additional issues related to writing about SSI are recommended for further research. 相似文献

To achieve the goal of scientific literacy, the skills of argumentation have been emphasized in science education during the
past decades. But the extent to which students can apply scientific knowledge to their argumentation is still unclear. The
purpose of this study was to analyse 80 Swedish upper secondary students’ informal argumentation on four socioscientific issues
(SSIs) to explore students’ use of supporting reasons and to what extent students used scientific knowledge in their arguments.
Eighty upper secondary students were asked to express their opinions on one SSI topic they chose through written reports.
The four SSIs in this study include global warming, genetically modified organisms (GMO), nuclear power, and consumption.
To analyse students’ supporting reasons from a holistic view, we used the SEE-SEP model, which links the six subject areas
of sociology/culture (So), environment (En), economy (Ec), science (Sc), ethics/morality (Et) and policy (Po) connecting with
three aspects, knowledge, value and personal experience (KVP). The results showed that students used value to a greater extent (67%) than they did scientific knowledge (27%) for
all four SSI topics. According to the SEE-SEP model, the distribution of supporting reasons generated by students differed
among the SSI topics. Also, some alternative concepts were disclosed in students’ arguments. The implications for research
and education are discussed. 相似文献

Low post-compulsory science enrolments for secondary students have been a growing concern across the Western world. Research
has examined factors relating to science curricula and students’ attitudes about science, but parental views of science education
remain largely unexplored in Australia. Because parents have a strong role in shaping their children’s subject selection and
career choices, in this pilot study we sought to explore parental attitudes about science education. Results from focus interviews
and a survey of 132 Indigenous and non-Indigenous parents demonstrated, for the first time, that regional parents believe
the study of society and the environment (SOSE) is a better preparation than science for their children’s understanding of
socio-scientific issues. Most parents were unclear as to the nature of scientific literacy, believing science as it is currently
taught in primary schools, not to be relevant to their children’s needs. Structural equation modelling using the survey data
confirmed prior researchers’ claims and extended ideas about the likely interplay of parental attitudes and beliefs influencing
their support of science study for their children. The results highlight an urgent need to explore such parental views across
Australia. 相似文献

Uncovering the Potential: The Role of Technologies on Science Learning of Middle School Students 总被引:1,自引:0,他引:1

There is, no doubt, untapped potential in using technological tools to enhance the understanding of science concepts. This
study examines the potential by observing 7th and 8th grade middle school students’ (n = 23) use of portable data collection devices in a nine-week elective class, Exploring Technologies. Students’ use of the data collection devices and subsequent interactions were traced through audiocassette and videocassette
recordings, field notes, and student artifacts. The culminating activity for the course was a scientific investigation that
required students to use the technologies to answer student-selected research questions. To illustrate the use of technology
as a mediatory tool, an inquiry investigation of three student groups is described. In examining the three groups of middle
school students the researchers encountered specific evidence of technology maximizing students’ science learning. The students
were able to use the portable data collection devices in their investigations as they discussed scientific ideas related to
temperature and heat. The study’s findings indicated that the three student groups were able to use the tools to conduct scientific
inquiry and engage in scientific discourse. Further research on instructional approaches that allow students to develop expertise
by using technology as tools to construct knowledge about complex phenomena is encouraged. 相似文献

With increasing numbers of students learning science through a second language in many school contexts, there is a need for
research to focus on the impact language has on students’ understanding of science concepts. Like other countries, Brunei
has adopted a bilingual system of education that incorporates two languages in imparting its curriculum. For the first three
years of school, Brunei children are taught in Malay and then for the remainder of their education, instruction is in English.
This research is concerned with the influence that this bilingual education system has on children’s learning of science.
The purpose was to document the patterns of Brunei students’ developing understandings of the concepts of living and non-living
things and examine the impact in the change in language as the medium of instruction. A cross-sectional case study design
was used in one primary school. Data collection included an interview (n = 75), which consisted of forced-response and semi-structured interview questions, a categorisation task and classroom observation.
Data were analysed quantitatively and qualitatively. The results indicate that the transition from Malay to English as the
language of instruction from Primary 4 onwards restricted the students’ ability to express their understandings about living
things, to discuss related scientific concepts and to interpret and analyse scientific questions. From a social constructivist
perspective these language factors will potentially impact on the students’ cognitive development by limiting the expected
growth of the students’ understandings of the concepts of living and non-living things.

We investigate students’ negative perceptions about an online peer assessment system for undergraduate writing across the
disciplines. Specifically, we consider the nature of students’ resistance to peer assessment; what factors influence that
resistance; and how students’ perceptions impact their revision work. We do this work by first examining findings from an
end-of-course survey administered to 250 students in ten courses across six universities using an online peer assessment system
called SWoRD for their writing assignments. Those findings indicate that students have the most positive perceptions of SWoRD
in those courses where an instructor graded their work in addition to peers (as opposed to peer-only grading). We then move
to an in-depth examination of perceptions and revision work among 84 students using SWoRD and no instructor grading for assessment
of writing in one university class. Findings from that study indicate that students sometimes regard peer assessment as unfair
and often believe that peers are unqualified to review and assess students’ work. Furthermore, students’ perceptions about
the fairness of peer assessment drop significantly following students’ experience in doing peer assessment. Students’ fairness
perceptions—and drops in those perceptions—are most significantly associated with their perceptions about the extent to which
peers’ feedback is useful and positive. However, students’ perceptions appear to be unrelated to the extent of their revision
work. This research fills a considerable gap in the literature regarding the origin of students’ negative perceptions about
peer assessment, as well as how perceptions influence performance. 相似文献

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

Emphasis on improving higher level biology education continues. A new two-step approach to the experimental phases within
an outreach gene technology lab, derived from cognitive load theory, is presented. We compared our approach using a quasi-experimental
design with the conventional one-step mode. The difference consisted of additional focused discussions combined with students
writing down their ideas (step one) prior to starting any experimental procedure (step two). We monitored students’ activities
during the experimental phases by continuously videotaping 20 work groups within each approach (N = 131). Subsequent classification of students’ activities yielded 10 categories (with well-fitting intra- and inter-observer
scores with respect to reliability). Based on the students’ individual time budgets, we evaluated students’ roles during experimentation
from their prevalent activities (by independently using two cluster analysis methods). Independently of the approach, two
common clusters emerged, which we labeled as ‘all-rounders’ and as ‘passive students’, and two clusters specific to each approach:
‘observers’ as well as ‘high-experimenters’ were identified only within the one-step approach whereas under the two-step conditions
‘managers’ and ‘scribes’ were identified. Potential changes in group-leadership style during experimentation are discussed,
and conclusions for optimizing science teaching are drawn. 相似文献

This study investigated the relationship between family factors and students’ scientific literacy performance in Hong Kong,
which has excelled in science performance in previous international studies. Data were obtained from the 2006 Programme for
International Student Assessment. Multilevel analysis was used to examine the relationship between parental involvement and
investment and students’ scientific literacy performance. It was found that students’ scientific literacy performance, which
was measured by their science achievement and self-efficacy towards science, were significantly associated with certain types
of parental investment and involvement even after controlling background factors of both students and schools. Parental investment
in cultural resources and parental involvement in terms of organising science learning enrichment activities at an early age
were found to be significantly associated with students’ scientific literacy performance. Activities that could be provided
at an early age (e.g. watching TV programmes about science, reading books on scientific discovery, watching, reading or listening
to science fictions) were found to be highly effective activities for promoting children’s science achievement and self-efficacy. 相似文献

“Accepting Emotional Complexity”: A Socio-Constructivist Perspective on the Role of Emotions in the Mathematics Classroom 总被引:1,自引:0,他引:1
Peter Op ’t Eynde Erik De Corte Lieven Verschaffel 《Educational Studies in Mathematics》2006,63(2):193-207
A socio-constructivist account of learning and emotions stresses the situatedness of every learning activity and points to the close interactions between cognitive, conative and affective factors in students’ learning and problem solving. Emotions are perceived as being constituted by the dynamic interplay of cognitive, physiological, and motivational processes in a specific context. Understanding the role of emotions in the mathematics classroom then implies understanding the nature of these situated processes and the way they relate to students’ problem-solving behaviour. We will present data from a multiple-case study of 16 students out of 4 different junior high classes that aimed to investigate students’ emotional processes when solving a mathematical problem in their classrooms. After identifying the different emotions and analyzing their relations to motivational and cognitive processes, the relation with students’ mathematics-related beliefs will be examined. We will specifically use Frank’s case to illustrate how the use of a thoughtful combination of a variety of different research instruments enabled us to gather insightful data on the role of emotions in mathematical problem solving. 相似文献

The purpose of this qualitative interpretive research study was to examine high school students’ written scientific explanations
during biology laboratory investigations. Specifically, we characterized the types of epistemologies and forms of reasoning
involved in students’ scientific explanations and students’ perceptions of scientific explanations. Sixteen students from
a rural high school in the Southeastern United States were the participants of this research study. The data consisted of
students’ laboratory reports and individual interviews. The results indicated that students’ explanations were primarily based
on first-hand knowledge gained in the science laboratories and mostly representing procedural recounts. Most students did
not give explanations based on a theory or a principle and did not use deductive reasoning in their explanations. The students
had difficulties explaining phenomena that involved intricate cause–effect relationships. Students perceived scientific explanation
as the final step of a scientific inquiry and as an account of what happened in the inquiry process, and held a constructivist–empiricist
view of scientific explanations. Our results imply the need for more explicit guidance to help students construct better scientific
explanations and explicit teaching of the explanatory genre with particular focus on theoretical and causal explanations. 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

This project explores conceptual continuity as a framework for understanding students’ native ways of understanding and describing. Conceptual continuity suggests that
the relationship between the use of words in one genre and the scientific genre can exist at varying levels of association.
This perspective can reveal the varied relationships between ideas explained in everyday or vernacular genres and their association
to scientific explanations. We conducted a 2-year study involving 15 high school baseball players’ understanding of the physics
involved in baseball. First, we conducted a quantitative assessment of their science understanding by administering a test
prior to season one (2006) and season two (2007). Second, we examined the types of linguistic resources students used to explain
their understanding. Third, we revisited our data by using conceptual continuity to identify similarities between students’ conceptual understanding in the informal contexts and their similarities to canonical
scientific ideas. The results indicated students’ performance on the multiple-choice questions suggested no significant improvement.
The qualitative analyses revealed that students were able to accurately explain different components of the idea by using
a diversity of scientific and non-scientific genres. These results call attention to the need to reconstruct our vision of
science learning to include a more language sensitive approach to teaching and learning. 相似文献

Learners’ ability in dealing with socio-scientific issues has been highlighted in contemporary science education. This study
explored the effects of different on-line searching activities on high school students’ cognitive structure outcomes and informal
reasoning outcomes. By using a quasi-experimental research approach, thirty-three students were assigned to a “guided searching
task group”, while thirty-five students were assigned to an “unguided searching task group”. The treatments of this study
were two different on-line searching activities. All the participants were asked to search relevant information regarding
nuclear power usage on the Internet during the period of two classes (100 min). However, the students in the un-guided searching
task group were asked to search freely, while those in the guided searching task group were provided with a searching guideline.
The participants’ cognitive structures outcomes as well as their informal reasoning outcomes regarding nuclear power usage
were assessed before and after the conduct of on-line searching tasks. The results of ANCOVA revealed that the students in
the guided on-line searching task group significantly outperformed their counterparts in the extent (p < 0.01) and the richness of their cognitive structures (p < 0.01). Also, they significantly outperformed their counterparts in the usage of the two information processing strategies,
“comparing” (p < 0.05) and “inferring or explaining” (p < 0.05). Moreover, it was also found that the students in the guided on-line searching task group only outperformed their
counterparts in their supportive argument construction (p < 0.05). In other words, the guided searching tasks did help the students obtain better cognitive structure outcomes; however,
the increments on their cognitive structure outcomes may only help them to propose more supportive arguments, but their rebuttal
construction (an important indicator for their reasoning quality) was not particularly improved. 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

In a European project—CoReflect—researchers in seven countries are developing, implementing and evaluating teaching sequences
using a web-based platform (STOCHASMOS). The interactive web-based inquiry materials support collaborative and reflective
work. The learning environments will be iteratively tested and refined, during different phases of the project. All learning
environments are focusing “socio-scientific issues”. In this article we report from the pilot implementation of the Swedish
learning environment which has an Astrobiology context. The socio-scientific driving questions are “Should we look for, and
try to contact, extraterrestrial life?”, and “Should we transform Mars into a planet where humans can live in the future?”
The students were in their last year of compulsory school (16 years old), and worked together in triads. We report from the
groups’ decisions and the support used for their claims. On a group level a majority of the student groups in their final
statements express reluctance towards both the search of extraterrestrial life and the terraforming of Mars. The support used
by the students are reported and discussed. We also look more closely into the argumentation of one of the student groups.
The results presented in this article, differ from earlier studies on students’ argumentation and decision making on socio-scientific
issues (Aikenhead in Science education for everyday life. Evidence-based practice. Teachers College Press, New York, (2006) for an overview), in that they suggest that students do use science related arguments—both from “core” and “frontier” science—in
their argumentation and decision making. 相似文献

Most studies indicate primary students’ attitudes towards and interest in science decline as they progress into the secondary
years. Longitudinal qualitative research exploring this phenomenon is rare as is research which focuses on the students’ voice
as they cross the interface. In this study multiple qualitative data sources, supported by a ‘science interest’ composite
scale, followed 20 students over 2 years. In contrast to baseline data on their peers these students, in general, maintained
their interest in science. Apart from identifying the teacher’s pedagogical approach and classroom environment as two key
issues in understanding these students’ journeys, the importance of listening to and heeding the students’ voice may be an
even more critical concern in addressing the decline in students’ attitudes and interest in science. 相似文献
