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 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

Teaching and Learning Physics in a 1:1 Laptop School 总被引：1，自引：1，他引：0
1:1 laptop programs, in which every student is provided with a personal computer to use during the school year, permit increased
and routine use of powerful, user-friendly computer-based tools. Growing numbers of 1:1 programs are reshaping the roles of
teachers and learners in science classrooms. At the Denver School of Science and Technology, a public charter high school
where a large percentage of students come from low-income families, 1:1 laptops are used often by teachers and students. This
article describes the school’s use of laptops, the Internet, and related digital tools, especially for teaching and learning
physics. The data are from teacher and student surveys, interviews, classroom observations, and document analyses. Physics
students and teachers use an interactive digital textbook; Internet-based simulations (some developed by a Nobel Prize winner);
word processors; digital drop boxes; email; formative electronic assessments; computer-based and stand-alone graphing calculators;
probes and associated software; and digital video cameras to explore hypotheses, collaborate, engage in scientific inquiry,
and to identify strengths and weaknesses of students’ understanding of physics. Technology provides students at DSST with
high-quality tools to explore scientific concepts and the experiences of teachers and students illustrate effective uses of
digital technology for high school physics. 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.

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

The purpose of this study was to understand the impact of an apprenticeship program on high school students’ understanding
of the nature of scientific inquiry. Data related to seventeen students’ understanding of science and scientific inquiry were
collected through open-ended questionnaires. Findings suggest that although engagement in authentic scientific research helped
the participants to develop competency in experimentation methods it had limited impact on participants’ learning of the implicit
aspects of scientific inquiry and NOS. Discussion focuses on the importance of making the implicit assumptions of science
explicit to the students in such authentic scientific inquiry settings through structured curriculum. 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 reports on an attempt to investigate Turkish primary school students’ interest in science by using their self-generated
questions. We investigated students’ interest in science by analyzing 1704 self-generated science-related questions. Among
them, 826 questions were submitted to a popular science magazine called Science and Children. Such a self-selected sample
may represent a group of students who have a higher level of motivation to seek sources of information outside their formal
education and have more access to resources than the students of low social classes. To overcome this problem, 739 students
were asked to write a question that they wanted to learn from a scientist and as a result 878 questions were gathered. Those
students were selected from 13 different schools at 9 cities in Turkey. These schools were selected to represent a mixture
of socioeconomic areas and also to cover different students’ profile. Students’ questions were classified into two main categories:
the field of interest and the cognitive level of the question. The results point to the popularity of biology, astrophysics,
nature of scientific inquiry, technology and physics over other science areas, as well as indicating a difference in interest
according to gender, grade level and the setting in which the questions were asked. However, our study suggests that only
considering questions submitted to informal learning environments, such as popular science magazines or Ask-A-Scientist Internet
sites has limitations and deficiencies. Other methodologies of data collection also need to be considered in designing teaching
and school science curriculum to meet students’ needs and interest. The findings from our study tend to challenge existing
thinking from other studies. Our results show that self-generated questions asked in an informal and a formal setting have
different patterns. Some aspects of students’ self-generated questions and their implications for policy, science curriculum
reform and teaching are discussed in this paper. 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

Students have been largely ignored in discussions about how best to teach science, and many students feel the curriculum is
detached from their lives and interests. This article presents a strategy for incorporating students’ interests into the formal
Biology curriculum, by drawing on the political meaning of “shadow government” as alternative policies developed by parties
not in office. A “shadow curriculum” thus reflects the interests and information needs of those who have no voice in deciding
what the formal curriculum should include, although they are the ones who are most influenced by it. High school students’
interests in three Biology topics were identified (n = 343) and retested on another student sample (n = 375), based on their solicited questions as indicators for interests. The results of this exploratory case study showed
that half of the questions asked by students in the areas of genetics, the cardiovascular system and the reproductive system
are not addressed by the national curriculum. Students’ questions were then expressed in the curricular language of principles,
phenomena and concepts in order to create a shadow curriculum. A procedure that could be used by other researchers and practitioners
to guide the development of a curriculum that is more aligned with student interests is suggested. 相似文献

Researchers who have investigated the public understanding of science have argued that fictional cinema and television has proven to be particularly effective at blurring the distinction between fact and fiction. The rationale for this study lies in the notion that to teach science effectively, educators need to understand how popular culture influences their students’ perception and understanding of science. Using naturalistic research methods in a diverse middle school we found that students who watched a popular science fiction film, The Core, had a number of misunderstandings of earth science concepts when compared to students who did not watch the movie. We found that a single viewing of a science fiction film can negatively impact student ideas regarding scientific phenomena. Specifically, we found that the film leveraged the scientific authority of the main character, coupled with scientifically correct explanations of some basic earth science, to create a series of plausible, albeit unscientific, ideas that made sense to students. 相似文献

Genetics is the cornerstone of modern biology and understanding genetics is a critical aspect of scientific literacy. Research
has shown, however, that many high school graduates lack fundamental understandings in genetics necessary to make informed
decisions or to participate in public debates over emerging technologies in molecular genetics. Currently, much of genetics
instruction occurs at the high school level. However, recent policy reports suggest that we may need to begin introducing
aspects of core concepts in earlier grades and to successively develop students’ understandings of these concepts in subsequent
grades. Given the paucity of research about genetics learning at the middle school level, we know very little about what students
in earlier grades are capable of reasoning about in this domain. In this paper, we discuss a research study aimed at fostering
deeper understandings of molecular genetics at the middle school level. As part of the research we designed a two-week model-based
inquiry unit implemented in two 7th grade classrooms (N = 135). We describe our instructional design and report results based on analysis of pre/post assessments and written artifacts
of the unit. Our findings suggest that middle school students can develop: (a) a view of genes as productive instructions
for proteins, (b) an understanding of the role of proteins in mediating genetic effects, and (c) can use this knowledge to
reason about a novel genetic phenomena. However, there were significant differences in the learning gains in both classrooms
and we provide speculative explanations of what may have caused these differences. 相似文献

Purposely Teaching for the Promotion of Higher-order Thinking Skills: A Case of Critical Thinking 总被引：1，自引：0，他引：1
This longitudinal case-study aimed at examining whether purposely teaching for the promotion of higher order thinking skills
enhances students’ critical thinking (CT), within the framework of science education. Within a pre-, post-, and post–post
experimental design, high school students, were divided into three research groups. The experimental group (n = 57) consisted of science students who were exposed to teaching strategies designed for enhancing higher order thinking
skills. Two other groups: science (n = 41) and non-science majors (n = 79), were taught traditionally, and acted as control. By using critical thinking assessment instruments, we have found
that the experimental group showed a statistically significant improvement on critical thinking skills components and disposition
towards critical thinking subscales, such as truth-seeking, open-mindedness, self-confidence, and maturity, compared with
the control groups. Our findings suggest that if teachers purposely and persistently practice higher order thinking strategies
for example, dealing in class with real-world problems, encouraging open-ended class discussions, and fostering inquiry-oriented
experiments, there is a good chance for a consequent development of critical thinking capabilities. 相似文献

This study investigated the impact of an open inquiry experience on elementary science methods students’ understanding of
celestial motion as well as the methods developed by students to answer their own research questions. Pre/post interviews
and assessments were used to measure change in participants’ understanding (N = 18). A qualitative approach was used to describe the nature of each participant’s investigation through an analysis of
their science journal and poster presentations. A comparison of participants’ inquiry projects with the change in their understanding
revealed that while most participants improved in both their area of inquiry and beyond, elementary science methods students
may need more guidance to reach a full scientific understanding across all aspects of celestial motion. 相似文献

Teaching students how to conduct authentic scientific inquiry is an essential aspect of recent science education reform efforts.
Our National Science Foundation-funded GK-12 program paired science graduate students—fellows—with secondary science teachers
in order to enhance inquiry-based instruction. This research examined the roles of the fellows, teachers, and school culture
in the implementation of inquiry and the fellows’ conceptions of classroom inquiry versus that in their own research. Qualitative
data were collected for two academic years. Overall, the classrooms shifted toward a more inquiry-oriented approach over the
academic year. Several aspects of school culture influenced inquiry implementation. Fellows described their research as similar
in overall structure but less constrained by known concepts, less guided by mentors, and more in-depth than that of secondary
school students. The teacher-fellow scientist partnership is a potentially effective professional development model to create
positive and lasting change within the science classroom. 相似文献

This paper reports an interpretive study that sought students' views about the role that practical work plays in their school
science lessons. Twenty-nine students aged between 13 and 16 years were selected from three secondary schools in England.
Data were collected from initial lesson observations and in-depth interviews in order to explore students’ views about practical
work. The findings suggest that students have three main reasons why practical work is important in their school science lessons:
for interest and activity, including social and personal features such as participation and autonomy; as an alternative to
other forms of science teaching involving a pedagogy of transmission, and as a way of learning, including memorizing and recall.
The findings are discussed in the context of a critical view of previous work on the role of practical work, work on attitudes
to science and on the student voice. The paper concludes that practical work is seen to provide opportunities for students
to engage with and influence their own learning but that learning with practical work remains a complex issue that needs further
research and evaluation about its use, effectiveness and of the role of scientific inquiry as a component of practical activity. 相似文献

Over the past twenty-five years researchers have been concerned with understanding the science student. The need for such
research is still grounded in contemporary issues including providing opportunities for all students to develop scientific
literacy and the failure of school science to connect with student’s lives, interests and personal identities. The research
reported here is unusual in its use of discourse analysis in social psychology to contribute to an understanding of the way
students make meaning in secondary school science. Data constructed for the study was drawn from videotapes of nine consecutive
lessons in a year-seven science classroom in Melbourne, post-lesson video-stimulated interviews with students and the teacher,
classroom observation and the students’ written work. The classroom videotapes were recorded using four cameras and seven
audio tracks by the International Centre for Classroom Research at the University of Melbourne. Student talk within and about
their science lessons was analysed from a discursive perspective. Classroom episodes in which students expressed their sense
of personal identity and agency, knowledge, attitude or emotion in relation to science were identified for detailed analysis
of the function of the discourse used by students, and in particular the way students were positioned by others or positioned
themselves. This article presents the discursive Umwelt or life-space of one middle years science student, Tasha. Her case
is used here to highlight the complex social process of meaning making in science classrooms and the need to attend to local
moral orders of rights and duties in research on student language use, identity and learning in science. 相似文献

This study is conducted with self-developed questionnaire on 910 middle school students, aimed at describing middle school
students’ academic subjective well-being and exploring its influential factors. Results show that (1) Academic subjective
well-being of middle school students is generally low and there exist differences in different schools and grades. Students
from non-key middle schools have lower academic subjective well-being than those from the key schools. Grade 2 students in
both junior and senior middle schools have the lowest academic subjective well-being. (2) Factors directly affecting middle
school students’ academic subjective well-being are academic experience and the present academic achievements · · with the
former playing a major role. (3) Factors indirectly influencing middle school students’ academic subjective well-being are
social pressure and expected academic achievements, both of which influence students’ academic subjective well-being through
students’ academic experience or their present academic achievements.
