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

We review Brown and Kloser’s article, “Conceptual continuity and the science of baseball: using informal science literacy
to promote students science learning” from a Vygotskian cultural-historical and dialectic perspective. Brown and Kloser interpret
interview data with student baseball players and claim that students’ conceptual understanding articulated in vernacular genres
involves continuities (similarities) with the canonical scientific explanations. In this commentary, we suggest that the authors’
approach presupposes the dichotomy of the formal and the informal, which brings the authors’ attention to continuity into
the separation of cognition from language. We propose a Vygotskian approach that points out the problem of theorizing cognition
(conceptual understanding) by depending on specific forms of representation (e.g., scientific terms). As alternative, we envision
a Vygotskian cultural-historical approach to language, which considers different, irreducible modes of communication as an
integrated whole and therefore allows theorizing cognition without dichotomizing it from the concrete ways by which human
being communicates. We provide an exemplary analysis of a lecture talk in a university physics classroom and exemplify dialectic
theories that explain the development of conceptual understanding. We discuss that this Vygotskian dialectic approach shows
that people communicate scientific concepts through hybridization, which does not reproduce a genre self-identically; the continuity of conceptual understanding involves dis/continuity. 相似文献

Learners’ Responses to the Demands of Conceptual Change: Considerations for Effective Nature of Science Instruction 总被引:1,自引:5,他引:1
Michael P. Clough 《Science & Education》2006,15(5):463-494
Much has been written about how effective nature of science instruction must have a significant explicit and reflective character.
However, while explicitly drawing students’ attention to NOS issues is crucial, learning and teaching the NOS are essentially
matters of conceptual change. In this article, how people learn and learners’ responses to the demands of conceptual change
are used to explain how students may exit from instruction with fundamental NOS misconceptions left intact or only slightly
altered, despite being explicitly and reflectively attended to more accurate ideas. The purpose of this concept paper is to
set within a theoretical framework of learning, and bring some coherence to, what has rapidly become a large body of empirical
research regarding effective NOS instruction. Toward these two ends, this article: (1) illustrates how a conceptual change
framework can be used to account for learners’ responses to NOS instruction and what teachers might do to promote understanding
NOS and transferring it to new contexts; (2) characterizes popularly advocated NOS instructional approaches along a continuum
marked by increasing connection to the workings of science, and decreased ability to dismiss NOS lessons as extraneous to
authentic science; and (3) proposes that NOS instruction would likely be more effective if teachers deliberately scaffolded
classroom experiences and students’ developing NOS understanding back and forth along the continuum. 相似文献

The objective of this study was to construct a teaching strategy for facilitating students’ conceptual understanding of the
boiling concept. The study is based on 52 freshman students in the primary science education department. Students’ ideas were
elicited by a test consisting of nine questions. Conceptual change strategy was designed based on students’ alternative conceptions.
Conceptual change in students’ understanding of boiling was evaluated by administering a pre-, post- and delayed post-test.
The test scores were analysed both by qualitative and quantitative methods. Statistical analysis using one-way ANOVA of student
test scores pointed to statistically significant differences in the tests and total scores (p < 0.05). Quantitative analysis of students’ responses on each test revealed different schema about changing their knowledge
system. Both qualitative and quantitative analyses suggest that the teaching activities facilitated students’ conceptual understanding.
No statistically significant differences were found between post-test and delayed post-test scores, suggesting that the teaching
strategy enabled students to retain their new conceptions in the long-term memory. 相似文献

Models are often used when teaching science. In this paper historical models and students’ ideas about genetics are compared.
The historical development of the scientific idea of the gene and its function is described and categorized into five historical
models of gene function. Differences and similarities between these historical models are made explicit. Internal and external
consistency problems between the models are identified and discussed. From the consistency analysis seven epistemological
features are identified. The features vary in such ways between the historical models that it is claimed that learning difficulties
might be the consequence if these features are not explicitly addressed when teaching genetics. Students’ understanding of
genetics, as described in science education literature, is then examined. The comparison shows extensive parallelism between
students’ alternative understanding of genetics and the epistemological features, i.e., the claim is strengthened. It is also
argued that, when teaching gene function, the outlined historical models could be useful in a combined nature of science and
history of science approach. Our findings also raise the question what to teach in relation to preferred learning outcomes
in genetics. 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

Delayed Understanding and Staying in Phase: Students’ Perceptions of their Study Situation 总被引:1,自引:0,他引:1
Max Scheja 《Higher Education》2006,52(3):421-445
Findings are presented from a study of undergraduate students’ experiences of understanding in first-year engineering. At
the end of their first year of study 86 Swedish students of electrical engineering and computer science were asked to reflect
in writing on their experiences of studying and learning. Fifteen of them also took part in interviews which explored in some
detail their experiences of understanding in relation to perceived constraints of the teaching-learning environment. The analyses
of the students’ written accounts and the interview data focused on the students’ experiences of studying and of understanding
in relation to course work in engineering. The majority of the students reported problematic first-year experiences and testified
to a sensation of ‘falling out of phase’ with their studies. This sensation was frequently coupled with a lag in coming to
understand course material, which may be characterised in terms of delayed understanding. The notion of delayed understanding is discussed in relation to ideas about students’ perceptions of the learning environment
and the impact that those perceptions might have on students’ opportunities to reflect on learning material and develop a
solid understanding of course material in engineering education. In conclusion, it is suggested that the the notion of delayed
understanding captures the complications of a study situation in which a perceived lack of time to reflect on learning material
obstructs students’ understanding of course material in engineering, and also points up a more general aspect of learning
observing that time to reflect on previous experiences is an essential component of the process of coming to understand learning
material in a particular educational setting. 相似文献

The purposes of this study were to investigate students’ conceptual learning outcomes and the effect of motivation on students’
conceptual learning outcomes in two different contexts: a Web-based and a classroom-based instruction, which incorporated
the Dual Situation Learning Model (DSLM). Nine classes of Grade eight students (N = 190) were involved in the study; five classes participated in a Web-based context and four classes in a regular classroom-based
context. The topic covered was chemical reaction. Students’ conceptual change outcomes were assessed using eight two-tier
pre/post conceptual tests during the instruction and the reaction rate integrated conceptual test at the end of the instruction.
Students’ motivation data were collected in the beginning and during instruction using the items from the Students’ Motivation
Toward Science Learning (SMTSL) questionnaire. The data were analyzed using ANOVA, ANCOVA, bivariate correlation, and multiple
regression analysis. Findings revealed that students’ motivational factors were correlated significantly with their conceptual
learning outcomes in both Web-based and classroom-based science teaching. In the Web-based context, students’ motivation during
the Web-based learning played a more important role on students’ conceptual learning outcomes than before learning. 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
Angelia Reid-Griffin Glenda Carter 《International Journal of Science and Mathematics Education》2008,6(2):329-350
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

This study draws on recent research on the central role of representation in learning. While there has been considerable research
on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated
in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study
indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through
an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study
of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational
modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal
accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced
teacher insights into students’ thinking. 相似文献

Charbel Niño El-Hani Eduardo Fleury Mortimer 《Cultural Studies of Science Education》2007,2(3):657-702
In this paper, we offer an intermediate position in the multiculturalism/universalism debate, drawing upon Cobern and Loving’s
epistemological pluralism, pragmatist philosophies, Southerland’s defense of instructional multicultural science education,
and the conceptual profile model. An important element in this position is the proposal that understanding is the proper goal
of science education. Our commitment to this proposal is explained in terms of a defense of an ethics of coexistence for dealing
with cultural differences, according to which social argumentative processes—including those in science education—should be
marked by dialogue and confrontation of arguments in the search of possible solutions, and an effort to (co-)live with differences
if a negotiated solution is not reached. To understand the discourses at stake is, in our view, a key requirement for the
coexistence of arguments and discourses, and the science classroom is the privileged space for promoting an understanding
of the scientific discourse in particular. We argue for “inclusion” of students’ culturally grounded ideas in science education,
but in a sense that avoids curricular multicultural science education, and, thus, any attempt to broaden the definition of
“science” so that ideas from other ways of knowing might be simply treated as science contents. Science teachers should always
take in due account the diversity of students’ worldviews, giving them room in argumentative processes in science classrooms,
but should never lose from sight the necessity of stimulating students to understand scientific ideas. This view is grounded
on a distinction between the goals of science education and the nature of science instruction, and demands a discussion about
how learning is to take place in culturally sensitive science education, and about communicative approaches that might be
more productive in science classrooms organized as we propose here. We employ the conceptual profile model to address both
issues. We expect this paper can contribute to the elaboration of an instructional multicultural science education approach
that eliminates the forced choice between the goals of promoting students’ understanding of scientific ideas and of empowering
students through education.

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

Elementary Teachers’ Teaching for Conceptual Understanding: Learning From Action Research 总被引:1,自引:0,他引:1
This study reports teachers’ learning through action research on students’ conceptual understanding. The study examined (a)
the teachers’ views about science teaching and learning, (b) the teachers’ learning about their teaching practices and (c)
the conditions that supported the teachers’ learning through action research. A total of 14 elementary in-service teachers’
course discussion, self-video reflection, action research reports, and learning reflection were analyzed. Findings revealed
that (a) the teachers in this study commonly espoused the importance of probing and utilizing students’ preconceptions in
science teaching, but they demonstrated various levels of epistemological understanding of student learning and teaching,
(b) the teachers experienced the action research as a means to evaluate science teaching methods and changing their teaching
practices, and (c) the teachers identified sharing goals, problems, and solutions as an essential supporting condition for
their learning through action research. Implications for professional development and further research are discussed. 相似文献

This study explored the effects of congruency between preferred and actual learning environment (PLE & ALE) perceptions on
students’ science literacy in terms of science concepts, attitudes toward science, and the understanding of the nature of
science in an innovative curriculum of High Scope Project, namely Sci-Tech Mind and Humane Heart (STMHH). A pre-/post-treatment
experiment was conducted with 34 Taiwanese tenth graders involved in this study. Participating students’ preferred learning
environment perception and pre-instruction scientific literacy were evaluated before the STMHH curriculum. Their perceptions
toward the actual STMHH learning environment and post-instruction scientific literacy were also examined after the STMHH.
Students were categorized into two groups; “preferred alignment with actual learning environment” (PAA) and “preferred discordant
with actual learning environment” (PDA), according to their PLEI and ALEI scores. The results of this study revealed that
most of the students in this study preferred learning in a classroom environment where student-centered and teacher-centered
learning environments coexisted. Furthermore, the ANCOVA analysis showed marginally statistically significant difference between
groups in terms of students’ post-test scores on scientific literacy with the students’ pre-test scores as the covariate.
As a pilot study with a small sample size aiming to probe the research direction of this problem, the result of marginally
statistically significant and approaching large sized effect magnitude is likely to implicate that the congruency between
preferred and actual learning environments on students’ scientific literacy is noteworthy. Future study of this nature appears
to merit further replications and investigations. 相似文献

In the learning sciences, students’ understanding of scientific concepts has often been approached in terms of conceptual change. These studies are grounded in a cognitive or a socio-cognitive approach to students’ understanding and imply a focus on the
individuals’ mental representations of scientific concepts and ideas. We approach students’ conceptual change from a socio-cultural
perspective as they make new meaning in genetics. Adhering to a socio-cultural perspective, we emphasize the discursive and
interactional aspects of human learning and understanding. This perspective implies that the focus is on students’ meaning
making processes in collaborative learning activities. In the study, we conduct an analysis of a group of students’ who interact
while working to solve problems in genetics. In our analyses we emphasize four analytical aspects of the students’ meaning
making: (a) the students’ use of resources in problematizing, (b) teacher interventions, (c) changes in interactional accomplishments,
and (d) the institutional aspect of meaning making. Our findings suggest that students’ meaning making surrounding genetics
concepts relates not only to an epistemic concern but also to an interactional and an institutional concern.

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.

Investigating the effectiveness of a POE-based teaching activity on students’ understanding of condensation 总被引:1,自引:0,他引:1
This article reports on the development of a Predict–Observe–Explain, POE-based teaching strategy to facilitate conceptual
change and its effectiveness on student understanding of condensation. The sample consisted of 52 first-year students in primary
science education department. Students’ ideas were elicited using a test consisting of five probe questions and semi-structured
interviews. A teaching activity composed of three Predict–Discuss–Explain–Observe–Discuss–Explain (PDEODE) tasks was employed,
based on students’ preconceptions identified with the test. Conceptual change in students’ understanding of condensation was
evaluated via a pre-, post-, and delayed post-test approach and students’ interviews. Test scores were analyzed using both
qualitative and quantitative methods. The findings suggested that the strategy helps students to achieve better conceptual
understanding for the concept of condensation and enables students to retain these new conceptions in their long-term memory. 相似文献

Students’ learning interests and attitudes toward science have both been studied for decades. However, the connection between
them with students’ life experiences about science and technology has not been addressed much. The purpose of this study is
to investigate students’ learning interests and life experiences about science and technology, and also their attitudes toward
technology. A total of 942 urban ninth graders in Taiwan were invited to participate in this study. A Likert scale questionnaire,
which was developed from an international project, ROSE, was adapted to collect students’ ideas. The results indicated that
boys showed higher learning interests in sustainability issues and scientific topics than girls. However, girls recalled more
life experiences about science and technology in life than boys. The data also presented high values of Pearson correlation
about learning interests and life experiences related to science and technology, and in the perspective on attitudes towards
technology. Ways to promote girls’ learning interests about science and technology and the implications of teaching and research
are discussed as well. 相似文献

This review explores Ben-Zvi Assaraf, Eshach, Orion, and Alamour’s paper titled “Cultural Differences and Students’ Spontaneous
Models of the Water Cycle: A Case Study of Jewish and Bedouin Children in Israel” by examining how the authors use the concept
of spontaneous mental models to explain cultural knowledge source of Bedouin children’s mental model of water compared to
Jewish children’s mental model of water in nature. My response to Ben-Zvi Assaraf et al.’s work expands upon their explanations
of the Bedouin children’s cultural knowledge source. Bedouin children’s mental model is based on their culture, religion,
place of living and everyday life practices related to water. I suggest a different knowledge source for spontaneous mental
model of water in nature based on unique history and traditions of South Korea where people think of water in nature in different
ways. This forum also addresses how western science dominates South Korean science curriculum and ways of assessing students’
conceptual understanding of scientific concepts. Additionally I argue that western science curriculum models could diminish
Korean students’ understanding of natural world which are based on Korean cultural ways of thinking about the natural world.
Finally, I also suggest two different ways of considering this unique knowledge source for a more culturally relevant teaching
Earth system education. 相似文献

This study investigated the effect of metaconceptual teaching interventions on students’ understanding of force and motion
concepts. A multimethod research design including quasi-experimental design and case study designs was employed to compare
the effect of the metaconceptual activities and traditional instruction and investigate students’ reactions to metaconceptual
teaching interventions. The participants (45 high school students in the USA) were enrolled in one of the two physics classes
instructed by the same science teacher. In the experimental group, students’ engagement in metaconceptual knowledge and processes
was facilitated through various instructional activities, including poster drawing, journal writing, group debate, concept
mapping, and class and group discussions. These activities were intended to facilitate students’ engagement in (a) becoming
aware of their existing and past conceptions, associated beliefs, everyday experiences, and contextual differences, (b) monitoring
their understanding of the new conception, the changes in ideas, and the consistency between existing and new conceptions,
and (c) evaluating the relative ability of competing conceptions to explain a physical phenomenon. In the comparison group,
the same content knowledge was explained by the teacher along with the use of laboratory experiments, demonstrations, and
quantitative problem solving. Students’ reactions to the designed instructional activities indicated that metaconceptual teaching
interventions were successful in facilitating students’ engagement in several types of metaconceptual functioning. The results
showed that students in the experimental group had significantly better conceptual understanding than their counterparts in
the comparison group and this positive impact remained after a period of 9 weeks. 相似文献
