This study investigated the effects of engaging students to collectively learn and work with knowledge in a computer-supported
collaborative learning environment called Knowledge Forum on their views about knowledge building theory and practice. Participants
were 24 teacher-education students who took a required course titled “Integrating Theory and Practice in Teaching.” Data mainly
came from (1) student discourse recorded in a Knowledge Forum database, (2) a survey that examined students’ views about knowledge
building, and (3) interviews with regard to students’ perceived barriers to implementing knowledge building theory in teaching.
Findings suggest that with sustained discourse to construct their collective understanding of the relationships between theory
and practice in teaching for a semester, the participants were able to attain more informed and practical views about knowledge
building theory. In addition, students’ perceived barriers to implementing knowledge building in teaching were identified
and strategies to help overcome these barriers discussed. 相似文献

Educational researchers have suggested that computer games have a profound influence on students’ motivation, knowledge construction,
and learning performance, but little empirical research has targeted preschoolers. Thus, the purpose of the present study
was to investigate the effects of implementing a computer game that integrates the prediction-observation-explanation (POE)
strategy (White and Gunstone in Probing understanding. Routledge, New York, 1992) on facilitating preschoolers’ acquisition of scientific concepts regarding light and shadow. The children’s alternative
conceptions were explored as well. Fifty participants were randomly assigned into either an experimental group that played
a computer game integrating the POE model or a control group that played a non-POE computer game. By assessing the students’
conceptual understanding through interviews, this study revealed that the students in the experimental group significantly
outperformed their counterparts in the concepts regarding “shadow formation in daylight” and “shadow orientation.” However,
children in both groups, after playing the games, still expressed some alternative conceptions such as “Shadows always appear
behind a person” and “Shadows should be on the same side as the sun.” 相似文献

Considerable research has been published on students' alternative conceptions of science concepts and the means of addressing
those alternative conceptions. However, few studies have been reported on students' conceptions of learning and consequent
learning processes and attempts to change such conceptions and processes. Recent research has shown that students' beliefs
can act as barriers to the implementation of educational reforms that aim to alter students' learning processes. In this study
an interpretive methodology was employed by a teacher participant-observer to investigate barriers to students' adoption of
an alternative referent for learning and its consequent learning strategies in a Grade 11 chemistry class. Student narratives
suggest that both “cold” and “hot” contextual factors influenced students' willingness to adopt an alternative referent. The
consideration of “hot” factors, including students' beliefs, trust of the teacher, and ownership of the change process, is
necessary if such change is to be understood more fully. The value and difficulties of a teacher adopting this researcher's
perspective are also explored. 相似文献

This study investigates the effective research-based characteristics of professional development (ERBCPD) of the National
Science Foundation’s GK-12 Program—a program which partners institutions of higher education with local school districts and
places science, technology, engineering, and mathematics graduates in the K-12 classroom with teachers. Final evaluations
of 26 GK-12 sites were analyzed with a priori and emergent content analyses, which included rigorous inter- and intra-reliability
testing. The results of the a priori analysis demonstrated that the GK-12 program incorporates all ERBCPD, but to drastically
varying degrees (76–5%). The a priori characteristics that appeared most often were “Treats Fellows as professionals,” and
“Professional development is on-going.” The two emergent characteristics included “Improves communication skills” and “Has
real world application.” 相似文献

The purpose of this mixed methods sequential explanatory study was to identify factors contributing to students’ persistence
in the University of Nebraska-Lincoln Distributed Doctoral Program in Educational Leadership in Higher Education by obtaining
quantitative results from surveying 278 current and former students and then following up with four purposefully selected
typical respondents to explore those results in more depth. In the first, quantitative, phase, five external and internal
to the program factors were found to be predictors to students’ persistence in the program: “program”, “online learning environment”,
“student support services”, “faculty”, and “self-motivation”. In the qualitative follow up multiple case study analysis four
major themes emerged: (1) quality of academic experiences; (2) online learning environment; (3) support and assistance; and
(4) student self-motivation. The quantitative and qualitative findings from the two phases of the study are discussed with
reference to prior research. Implications and recommendations for policy makers are provided. 相似文献

The workplace, especially the academic department or division, provides an intriguing research site for study of correlates
of scholarly performance. The objective of this study was to estimate a correlate model of three-year scholarly performance
of clinical faculty in colleges of pharmacy. Two-hundred and ninety-six clinical faculty in pharmacy responded to an author-developed
questionnaire. The scholarly performance items factored into three dimensions: “Refereed Research,”, “Grants/Books Research,”
and “Nonresearch Scholarship.” A fourth single-item variable, “Contracts,” was also used as a dependent dimension. Eight correlates,
including two related to the departmental workplace, emerged as factors significantly explaining the variation in scholarly
performance. The two most significant were “Off-Campus Conversations” and “Department: Percent Time in Research.” These results
as well as others were contrasted with prior correlate studies and suggestions were made for future additional study. 相似文献

Research in Mexican schools, drawing upon earlier research in the UK, has led to the development and use of a method for describing, comparing and evaluating the particular approaches and interactional strategies used by teachers and learners. Using this method, qualitative and quantitative comparisons are made to distinguish between teachers who use a conventional, formal, directive approach when teaching 5-year-old children mathematical skills (called the “Official” method) and those who use a more interactive, collaborative, supportive, “scaffolded” approach to teach similar classes of children (called the “High Scope” method). In an earlier study, we found more competent and independent problem-solving among High/Scope pupils than among their peers taught by the Official method. In the present study, discourse analysis and statistical analysis of the relative frequencies of types of teacher-pupil interaction in the classrooms of two “Official” teachers and two “High’ Scope” teachers are used to explain the improved problem-solving of the “High Scope” pupils. The findings support the view that by creating a more collaborative, scaffolded version of classroom education, teachers can more successfully enable children to develop their own problem-solving skills, learning strategies and curriculum-related understanding. The research also contributes to the development and implementation of methods for promoting a more effective style of teacher-learner interaction in the classroom. 相似文献

The acceptance of new chemical ideas, before the Chemical Revolution of Lavoisier, in Greek-speaking communities in the 17th
and 18th centuries did not create a discourse of chemical philosophy, as it did in Europe, but rather a “philosophy” of chemistry
as it was formed through the evolution of didactic traditions of Chemistry. This “philosophical” chemistry was not based on
the existence of any academic institutions, it was focused on the ontology of principles and forces governing the analysis/synthesis
of matter and formulated two didactic traditions. The one, named “the system of chymists”, close to the Boylean/Cartesian
tradition, accepted, contrary to Aristotelianism, the five “chymical” principles and also the analytical ideal, but the “chymical”
principles were not under a conceptual and experimental investigation, as they were in Europe. Also, a crucial issue for this
tradition remained the “mechanical” principles which were under the influence of the metaphysical nature of the Aristotelian
principles. The other, close to the Boylean/Newtonian tradition, was the integrated presentation of the Newtonian “dream”,
which maintained a discursive attitude with reference to the “chemical attractions”–“chemical affinities” and actualised the
mathematical atomism of Boscovich, according to which the elementary texture of matter could be causally explained within
this complex architecture of mathematical “punkta”. In this tradition also coexisted, in a discursive synthesis, the “chemical element” of Lavoisier and the arguments of the
new theory and its opposition to the phlogiston theory, but the “chemical affinities” were under the realm of the “physical
element” as “metaphysical point”. 相似文献

In a previous series of studies, a model of comprehensive competence-based vocational education (CCBE model) was developed,
consisting of eight principles of competence-based vocational education (CBE) that were elaborated for four implementation
levels (Wesselink et al. European journal of vocational training 40:38–51 2007a). The model thus consisted of 32 cells, all defined by text. It was developed to provide study programme teams working in
vocational education with an instrument to assess the actual and desired “competentiveness” of their study programmes. “Competentiveness”
refers to the extent to which study programmes are based on the principles of CBE that we formulated. The model is an instrument
for analysing the alignment of study programmes with the defining principles of CBE and clarifying programme teams’ intentions,
i.e. the extent to which they wish to achieve higher levels of implementation of the different principles. This article presents
the results of two studies, the aim of which was to identify adjustments the teachers felt were necessary to make the CCBE
model a valid instrument for assessing the actual and desired “competentiveness” of their study programmes. In study A, 57
teachers evaluated the model during focus group discussions, resulting in a revised CCBE model consisting of ten principles
for five levels of implementation. In study B, 151 teachers completed a questionnaire to evaluate the comprehensibility of
the revised model. The study showed that teachers understood and interpreted the revised model as intended, were able to position
their study programmes by using the revised model and that the content validity of the revised model was good. 相似文献

The demographic changes in Greek schools underline the need for reconsidering the way in which migrant pupils move from their
everyday culture into the culture of school science (a process known as “cultural border crossing”). Migrant pupils might
face difficulties when they attempt to transcend cultural borders and this may influence their progress in science as well
as the construction of suitable academic identities as a means of promoting scientific literacy. In the research we present
in this paper, adopting the socioculturally driven thesis that learning can be viewed and studied as a meaning-making, collaborative
inquiry process, we implemented an action research program (school year 2008–2009) in cooperation with two teachers, in a
primary school of Athens with 85% migrant pupils. We examined whether the two teachers, who became gradually acquainted with
cross-cultural pedagogy during the project, act towards accommodating the crossing of cultural borders by implementing a variety
of inclusive strategies in science teaching. Our findings reveal that both teachers utilized suitable cross-border strategies
(strategies concerning the establishment of a collaborative inquiry learning environment, and strategies that were in accordance
with a cross-border pedagogy) to help students cross smoothly from their “world” to the “world of science”. A crucial key
to the teachers’ expertise was their previous participation in collaborative action research (school years 2004–2006), in
which they analyzed their own discourse practices during science lessons in order to establish more collaborative inquiry
environments. 相似文献

Within the sphere of contemporary social sciences, the terms “modernity,” “post-modernity” and “globalization” have penetrated,
as the core concepts, into various fields of social sciences in a logical way. In constituting the concept of “modernity,”
sociology of education develops the educational theory, as sociological theory does, into a “grand narrative” and “foundationalist”
theory; the contribution of post-modernity is pluralism and self-examination in an attempt to transcend modernity. Globalization,
a kind of expanded modernity, makes education sociologists broaden their perspective from single and traditional “nationality,”
“society” and “nation” to an international society and even to the global society, which has broken through the research paradigm
of modernity with ethnocentrism, anthropocentrism and Euro-centrism. These changes have required urgent constitution of the
conceptions and theoretical frameworks of sociology of education to be applied on a global level.

This follow-up study to van Kraayenoord and Schneider (1999) examined the performance in reading, metacognition and motivation
related to reading of students in Grades 7 and 8. Results showed significant correlations between all of the variables. A
multivariate analysis of variance showed that “good” and “poor” readers differed in reading self-concept and metacognitive
measures related to reading and memory. A stepwise regression analysis suggested that the metacognitive variables were the
best predictors of reading. Furthermore, a comparison of the results of the previous study with those of the current investigation
revealed that the findings were stable over time. Since the period between the two studies is the time during which students
make important decisions related to enrolment in one of three distinct school-types in Germany, we examined the results of
various groups of students: those in “Gymnasium” (high educational track), “Realschule” (middle educational track), and “Hauptschule”
(low educational track). Students in the Gymnasium scored significantly better than students in the other two groups on almost
all variables related to reading. A re-analysis of the data from our first investigation found that the results of the Gymnasium
students in the second study could be predicted from their results obtained during elementary school. 相似文献

Comparing efficiency in a cross-country perspective: the case of Italian and Spanish state universities 总被引：1，自引：0，他引：1
The growing internationalization of European Higher Education requires more emphasis on cross-country comparisons. In this
paper, an efficiency analysis of Italian and Spanish universities is conducted; as well as from a comparative perspective.
The efficiency scores are obtained using data envelopment analysis. The results demonstrate a good average efficiency in both
countries relative to each “country-specific” frontier; but when compared together, Italian universities seem relatively more
efficient. Malmquist indexes show, in both cases, efficiency improvements in the period considered. In the Italian case, this
improvement is due to major “technological changes”; that is, the introduction of some structural reforms in the sector (e.g.,
Bachelor/Master curricula). In the Spanish case, there is an improvement in “pure” efficiency, which is due to new funding
models. Further stages of the study underline the role of “regional effects”, probably due to different socio-economic conditions
in Italy, and to the decentralization process in Spain. 相似文献

Based on the analysis of primary energy consumption structure in five main provinces or municipalities in China, the factors
that affect carbon emissions in the five study areas are analyzed quantitatively and comparatively with the decomposition
analysis method. Empirical results demonstrate that the decomposition models of carbon emissions can be defined as “municipality
model” and “provincial model”, and the population factor of “municipal model” plays a significant role in carbon emissions
than that of “provincial model”. Either positive or negative effects of energy structure can be found in five different areas.
However, there is a general trend that energy structure effort is becoming more and more important. Based on the characteristics
and trends of carbon emissions in different areas, the carbon reduction measures are proposed as well. 相似文献

Based on empirical findings and theoretical considerations related to the field of expertise research, the importance of “types”
and “qualities” of knowledge in relation to problem solving in physics was investigated. The students (N =138) in this study had a level of competence that corresponds to an intensive beginner college course in physics. It was
found that conceptual declarative knowledge and problem scheme knowledge are excellent predictors of problem solving performance.
However, a detailed analysis shows that the first knowledge type is more typical for low achievers (novices) in physics problem
solving whereas the second type is predominately used by high achievers (experts). Regarding types and qualities of knowledge
and their relations to problem solving, the results of a multidimensional scaling analysis (MDS) indicate that two dimensions
of knowledge can be distinguished. On the extreme limits of the first dimension, which could be named “problem solving relevance
vs. structure of discipline”, are the types of knowledge and the qualities of knowledge, respectively. The second dimension
of knowledge could be named “single knowledge elements vs. organised knowledge units”. There are types of knowledge as well
as qualities of knowledge distributed along this dimension. Consequences of these results for improving physics education
are discussed. 相似文献

Conclusion I applaud ISTE, AASL, AECT, and the other organizations involved for tackling the “messy work” of developing standards for
the use of technology and information resources in schools. And, at the same time, I call for a “second generation” of standards
that define realistic expectations for teachers based on the subjects and levels they are called upon to teach. I propose
that professional organizations from each subject work with ISTE and AECT to complete this huge task, and I propose that we
consider as a “next step” the creation of a set of on-line learning experiences through which teachers can gain the identified
skills and knowledge by using the very technologies we’re hoping they’ll embrace in their own teaching.
There’s an old saying, “If you don’t know where you’re going, any road will do.” As far as educational technologies are concerned,
this is also true. For many, the goal seems to have been simply to “get more computers into the schools,” without much thought
about purpose. To return to Phil Schlechty’s metaphor, It’s generally been a brief and misguided “Ready” stage (occupied with
questions like “How many do we need?” “What type?” “Where?” and “How shall we connect them?”), followed by “Fire!” (the acquisition
and installation of equipment). What we need is: “Ready” (the creation of appropriate teams of people who will combine their
insights to plan for the district)... “Aim” (a series of discussions about what technologies can accomplish for schools and
the students they serve)... “Fire” (acquisition, installation, and professional development according to plan)... “Aim” (an
assessment of how well the technologies and related programs met the intended goals, and a new planning effort designed to
close the gap)... “Fire” (acquisition and implementation designed to eliminate the gap)... “Aim” (another gap assessment)...
“Fire” (another attempt to close gaps)..., And so on. 相似文献

This paper reports findings from a study of LookJed, the oldest and largest on-line forum for Computer Mediated Discussion
among individuals interested in Jewish education. The study adopted a “cyber-ethnographic” approach, with postings to the
forum seen as “acts of communication” that reveal what is important to their authors. An interest in exploring similarities
between forum conversations and those in teachers’ lounges led to an investigation of Herring’s claim that most listservs
do not include discussion at all, only the trading of information. This investigation found that active forum participants
generally use the forum for discrete purposes, most commonly to exchange information about “subject matter” or “teaching material”,
less commonly to exchange opinions and ideas, and rarely to do both. Integrating an analysis of patterns of contribution with
an examination of their discursive content reveals six preeminent “types” among the population of contributors, each of whom
participates in the forum in different ways and acts with different purposes. Although this typology is at best suggestive
and needs to be tested against other listserv cases, its easy identification suggests that in order to better understand the
cultures of virtual forums, it is important to pursue a more variegated characterization of listserv participants and their
motivations than has typically been the case in CMD research where users are most frequently identified as either lurkers
or fanatics, or as active or passive participants. 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

We analyse and explore, in the form of dialogues and metalogues questions about the dialogic nature of beliefs and students
belief talk about the nature of science and scientific knowledge. Following recent advances in discursive psychology, this
study focuses not on students' claims but on the discursive resources and dialogical practices that support the particular
claims they make. We argue that students' discourse is better understood as a textual bricolage that is sensitive to conversational
context, common sense, interpretive repertoires, and textual resources available in the conversational situation. Our text
is reflexive as it embodies the discursive construction of knowledge and undercuts any claims to authoritative knowledge.
The very conception of “belief” is itself an expression or construction from within the mundane idiom.... We learn to use
“belief” in conditions when the “objective facts” are unknown or problematic and we want to indicate the tenuous character
of our claim.... The notion of “real world” or “objective reality” is embedded in an extensive, pervasive language game which
includes as an intelligible move or possibility the use of the very concept of “belief” itself. (Pollner, 1987, p. 21) 相似文献
