This paper mainly describes the role of the multimedia software package ‘Interactions between Objects’ on students’ learning
of mechanical interaction forces and Newton’s laws. We designed and developed this software within social constructivism on
the basis of 226 students’ initial conceptions (categorized in six categories), in order to help students construct appropriate
knowledge about the subject. Teaching with the software was conducted in 13 primary, lower secondary and upper secondary school
classes. In the software’s evaluation research 226 students (aged 11–16) and 13 teachers of the classes participated. Data
analysis showed students’ substantial learning gains with respect to their initial alternative conceptions of the six conceptual
categories. Particularly, the students’ incorrect answers to the post-test questionnaire have perceptibly decreased (a mean
of 65%). In contrast, their correct answers to the questions reached high percentages, from 60% to 90% depending on the question
and the students’ age. Also the teachers’ opinions and comments enhanced software’s evaluation. The contribution of the software’s
specific characteristics on students’ learning is discussed along with implications for designing constructivist science learning
tools. 相似文献

The influence of homework experiences on students’ academic grades was studied with 223 college students. Students’ self-efficacy
for learning and perceived responsibility beliefs were included as mediating variables in this research. The students’ homework
influenced their achievement indirectly via these two self-regulatory beliefs as well as directly. Self-efficacy for learning,
although moderately correlated with perceptions of responsibility, predicted course grades more strongly than the latter variable.
No gender differences were found for any of the variables, a finding that extends prior research based on high school girls.
Educational implications about the importance of students’ homework completion and its relationship to college students’ development
of self-regulation and positive self-efficacy beliefs is discussed from a social cognitive perspective. 相似文献

There is a documented need for more opportunities for teachers to learn about students’ mathematical reasoning. This article
reports on the experiences of a group of elementary and middle school mathematics teachers who participated as interns in
an after-school, classroom-based research project on the development of mathematical ideas involving middle-grade students
from an urban, low-income, minority community in the United States. For 1 year, the teachers observed the students working
on well-defined mathematical investigations that provided a context for the students’ formation of particular mathematical
ideas and different forms of reasoning in several mathematical content strands. The article describes insights into students’
mathematical reasoning that the teachers were able to gain from their observations of the students’ mathematical activity.
The purpose is to show that teachers’ observations of students’ mathematical activity in research sessions on students’ development
of mathematical ideas can provide opportunities for teachers to learn about students’ mathematical reasoning. 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

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 investigated Indonesian and Japanese students’ understandings of macroscopic and submicroscopic levels of representing
matter and its changes and the difficulties they have with these concepts. A multiple-choice questionnaire was constructed
and delivered to 447 Indonesian and 446 Japanese public senior high school students. The data were analyzed using quantitative
and qualitative methods. The findings of the study show students’ understandings of macro- and submicroscopic levels are stronger
for higher-grade levels, except that the Indonesian students’ pattern is slightly different. The average percentage of students
responding correctly on the macroscopic level ranges between 62% and 69% (Indonesia) and between 58% and 73% (Japanese), whereas
on the submicroscopic level ranges between 56% and 62% (Indonesian) and 44% and 66% (Japanese). Their understandings of the
macroscopic level, however, are higher than for the submicroscopic level. The soundness of students’ understandings of the
concepts increases with grade level, except for Indonesian pattern slightly different. The average percentage of students
responding correctly ranges between 37% and 48% (Indonesian) and between 28% and 52% (Japanese). Furthermore, students’ level
of sound understandings of the concepts is lower than their understandings on either the macroscopic level or the submicroscopic
level. It is found that students have great difficulties with and hold some alternative conceptions of the concepts of homogeneous
mixtures, phase changes from solid to liquid, and phase changes from solid to gas. The study has implications, for example,
the use of several routes to meaningful learning and the careful use of technical words. 相似文献

INVESTIGATING THE EFFECTIVENESS OF AN ANALOGY ACTIVITY IN IMPROVING STUDENTS’ CONCEPTUAL CHANGE FOR SOLUTION CHEMISTRY CONCEPTS 总被引：1，自引：0，他引：1

This paper reports on an investigation on the use of an analogy activity and seeks to provide evidence of whether the activity
enables students to change alternative conceptions towards views more in accord with scientific views for aspects of solution
chemistry. We were also interested in how robust any change was and whether these changes in conceptual thinking became embedded
in the students’ long-term memory. The study has its theoretical basis in an interpretive paradigm, and used multiple methods
to probe the issues in depth. Data collection consisted of two concept test items, one-on-one interviews, and student self-assessment.
The sample consisted of 44 Grade 9 students selected from two intact classes (22 each), from Trabzon, Turkey. The interviews
were conducted with six students selected because of evidence as to their significant conceptual change in solution chemistry.
The research findings revealed statistically significant differences in pre-test and post-test scores, and pre-test and delayed
post-test scores (p<0.05), but no differences between post-test and delayed test scores (p>0.05). This suggests that the analogy activity is helpful in enhancing students’ conceptual understanding of solution chemistry,
and that these changes may be stored in the students’ long-term memory. 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

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

As an action research project, using mixed methodology, this study investigated how the use of math journals affected second
grade students’ communication of mathematical thinking. For this study, math journal instruction was provided. The data gathering
included pre- and post- math assessment, students’ math journals, interviews with the students, and teacher’s reflective journal.
Findings of the study indicated that the use of math journals positively influenced the students’ communication of mathematical
thinking and the use of math vocabulary. Additionally, math journals served as a communication tool between the students and
teacher and an assessment tool for the teacher. The implications of this study regarding students’ writing ability and time
constraints issues were also discussed. 相似文献

The purpose of this article is to examine students’ views on the blended learning method and its use in relation to the students’
individual learning style. The study was conducted with 31 senior students. Web based media together with face to face classroom
settings were used in the blended learning framework. A scale of Students’ Views on Blended Learning and its implementation,
Kolb’s Learning Style Inventory, Pre-Information Form and open ended questions were used to gather data. The majority of the
students’ fell into assimilators, accommodators and convergers learning styles. Results revealed that students’ views on blended
learning method and its use are quite positive. 相似文献

Components of Conceptual Ecologies 总被引：1，自引：0，他引：1

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

New representational technologies, such as virtual microscopy, create new affordances for medical education. In the article, a study on the following two issues is reported: (a) How does collaborative use of virtual microscopy shape students’ engagement with and learning from virtual slides of tissue specimen? (b) How do visual and conceptual cues scaffold students’ reasoning? Fifteen pairs of medical students participated in two sessions in which the students used a virtual microscope as a diagnostic tool in the context of learning pathology. The slides provided the students with varying levels of visual and conceptual cueing. The sessions were videotaped, and the students’ reasoning while using the microscope was analysed. The students’ written answers were analysed in terms of the findings they made and the diagnoses suggested. At a general level, the results show that students engage actively in this kind of virtually-mediated environment. The visual and/or conceptual cues improve students’ performance, and guide the students’ perception and reasoning in a manner that is productive from the point of view of learning to make clinically relevant observations. Scaffolding students’ reasoning process through cues furthermore assists the students in avoiding the most obvious pitfalls such as overlooking critical areas of a specimen. Overall, visual and conceptual cues improve students’ reasoning in perceptual and cognitive terms, while still allowing space for the making of “relevant mistakes” that may further the students’ diagnostic skills. 相似文献

This article reports research from a 3 year digital learning project to unite conceptual change and scientific reasoning in
the learning unit of combustion. One group of students had completed the course combining conceptual change and scientific
reasoning. The other group of students received conventional instruction. In addition to the quantitative data, six students
from each group were interviewed to evaluate their conceptual change, correct concepts and scientific reasoning. Results indicate
that the experimental group’s students significantly outperformed the conventional group on the Combustion Achievement Test
(CAT), Scientific Reasoning Test (SRT) and Combustion Dependent Reasoning Test (CDRT). Moreover, the experimental group’s
students use higher levels of scientific reasoning more frequently and changed their alternative concepts more successfully
than did the conventional group. Furthermore, once the experimental group’s students’ successfully changed their conceptions,
their concepts tended to be more stable than the conventional group’s students, even after the 6th week of learning. These
results demonstrate that combining conceptual change and scientific reasoning indeed improves students’ conceptual change
and scientific reasoning ability more effectively than conventional instruction. 相似文献

The purpose of this study is to examine the combined effect of self-efficacy and academic integration on higher education
students studying IT (Information Technology) majors in Taiwan. We introduced self-efficacy, which is a psychological factor
that affects students’ academic outcomes, as a new factor in Tinto’ theory, a well-known framework in student retention research.
Academic integration is the main proposition of Tinto’s theory affecting students’ decision to dropout. Students from different
populations have various reasons from dropping out of their studies. An examination of the relationship between self-efficacy
and academic integration is useful to understand the effect of self-efficacy on academic outcomes on the IT student population
in Taiwan. Data from a Taiwanese national survey database conducted in 2005 was used to achieve the research objective. A
total of 2,895 records were extracted from 75,084 students in public and private institutions studying in two IT-related Majors,
namely Information Management (IM) and Computer Science (CS). MANOVA was used to analyze the interaction effects between academic
integration and self-efficacy. The independent variables were institution types and students’ majors. The results showed that
students from public institutions have higher levels of self-efficacy than students from private ones. Another finding is
that IM students seem to have better study strategies and habits than CS students. However, CS students were found to have
better collaboration and satisfaction with their institutions than IM students. Team projects, counselling services, and flexible
teaching and learning strategy are suggested to enhance students’ academic integration and self-efficacy. 相似文献

From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central
to a domain can maximize students’ effort associated with constructing new schemas. In addition, interfaces that minimize
working memory demands due to the interface per se, for example by mimicking existing non-digital work practice, can preserve
students’ attentional focus on their learning task. In this research, we asked the question: What type of interface input capabilities provide best support for science problem solving in both low- and high-performing students? High school students’ ability to solve a diverse range of biology problems was compared over longitudinal sessions while
they used: (1) hardcopy paper and pencil (2) a digital paper and pen interface (3) pen tablet interface, and (4) graphical
tablet interface. Post-test evaluations revealed that time to solve problems, meta-cognitive control, solution correctness,
and memory all were significantly enhanced when using the digital pen and paper interface, compared with tablet interfaces.
The tangible pen and paper interface also was the only alternative that significantly facilitated skill acquisition in low-performing
students. Paradoxically, all students nonetheless believed that the tablet interfaces provided best support for their performance,
revealing a lack of self-awareness about how to use computational tools to best advantage. Implications are discussed for
how pen interfaces can be optimized for future educational purposes, and for establishing technology fluency curricula to
improve students’ awareness of the impact of digital tools on their performance. 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

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

The purpose of this case-study is to narrate a secondary science teacher’s experience of his professional development (PD)
education and training in innovative technologies (IT) in the context of engaging students in environmental research projects
The sources from which the narrative is derived include (1) the science teacher’s reflective reports during three summer institute
programs and (2) the science teacher’s reflective reports while subsequently engaging students in IT-embedded environmental
research projects in his classroom. The science teacher’s explanations for changes in students’ perception of their IT fluency
illuminate his personal narrative. The science teacher attributed his growth and significant changes in students’ perceptions
of their IT fluency to the following mechanisms: (a) a personal commitment to developing his own and his students’ IT abilities
in the context of doing environmental research projects, and (b) an increase in class time devoted to science education due
to school-time scheduling policy. The study implies that immersive professional development opportunities have the potential
to produce significant increases in students’ perceptions of their IT fluency. 相似文献
