This study investigates the mechanisms of scaffolding in a synchronous network-based environment – the ‘collaborative virtual
workplace’. A theoretical ‘multi-actor’ scaffolding model was formulated. The study itself focused on the role and inter-relations
of verbal scaffolding by tutor and peers during a collaborative process of making decisions about environmental issues. The analysis drew on data from the decision-making
discussions of 31 groups – material that was saved automatically by the learning environment software. The age of the 62 students
ranged from 14 to 17. Discourse act categories were devised to describe the tutor’s and the students’ task-related, supportive
and social communicative acts. The scaffolding situation was characterized through a causal discourse act interaction approach.
Tutor and students appeared to be elaborating and replacing each other’s process scaffolding acts in the collaborative decision-making
situation. The influence of certain tutor’s and students’ inter-related scaffolding patterns on students’ decision-making
provided empirical support for the ‘multi-actor’ scaffolding model.

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

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

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 aim of this study is to determine fifth-grade students’ metacognitive knowledge and skills and its relationship with mathematics
achievements. A total of 242 primary school students from six different schools were participated in the study. Turkish version
of Metacognitive Knowledge and Skills Assessment (MSA-TR) was used to measure metacognitive knowledge and skills. The results
demonstrated a significant and positive relationship (r = .648, p < .01) between metacognition and mathematics achievement. Furthermore, research results showed that 42% of total variance
of mathematics achievement could be explained with metacognitive knowledge and skills. 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.

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

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

In Finnish VET, students’ work experience is explicitly defined as workplace learning, instead of the practice of already
learnt skills. Therefore, vocational students’ learning periods in the workplace are goal-oriented, guided and assessed. This
paper examines the characteristics of students’ workplace learning and compares them with the characteristics of employees’
workplace learning. The data were collected with an Internet questionnaire from final-year vocational students (N = 3106). In total, 1603 students (52 %) answered the questionnaire. The data were analysed using quantitative methods. The
results indicate that features typical of employees’ workplace learning can also be found in student learning as well. However,
VET-related workplace learning has a number of characteristics that have not been brought to light in research on employees’
workplace learning thus far. We suggest that in developing educational practices it would be useful to draw on some of the
features of workplace learning such as the use of collaboration and shared practices; conversely for workplace practices it
would be useful to draw on some of the features of educational practices. For example, by utilising the structures of students’
workplace learning system presented in this study, learning at work could be transformed towards more goal-directed, guided
and assessed activity. 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

This study examines the effectiveness of three scaffolding conditions on adolescents’ learning about the circulatory system
with a hypermedia learning environment. One hundred and eleven adolescents (n = 111) were randomly assigned to one of three scaffolding conditions (adaptive scaffolding (AS), fixed scaffolding (FS),
or no scaffolding (NS)) and were trained to use a hypermedia environment to learn about the circulatory system. Pretest and
posttest data were collected to measure the qualitative changes in students’ mental models of the topic and quantitative changes
in their declarative knowledge. Verbal protocols were collected during the 40-minute learning task to examine how each condition
affected the way in which students regulated their learning. Findings revealed that learners in both the AS and NS conditions
gained significantly more declarative knowledge than did those in the FS condition. Also, the AS condition was associated
with shift in learners’ mental models significantly more than the other conditions. Associated with these significant shifts
in their mental models, learners in the AS condition regulated their learning by planning and activating prior knowledge,
monitoring their cognitive activities and their progress toward learning goals, using several effective strategies, and engaging
in adaptive help-seeking. By contrast, those in the NS condition used fewer effective strategies, while those in the FS regulated
their learning by using several regulatory processes which seemed to impede their learning. Implications for the design of
scaffolds for fostering students’ self-regulated learning with hypermedia are presented. 相似文献

This study investigated the effects of two contrasting learning environments on students’ course experiences: a lecture-based
setting to a student-activating teaching environment. In addition, the evaluative treatment involved five research conditions
that went together with one of four assessment modes, namely, portfolio, case-based, peer assessment, and multiple-choice
testing. Data (N = 608) were collected using the Course Experience Questionnaire. Results showed that the instructional intervention (i.e.
lectures versus student-activating treatment) influenced students’ course experiences, but in the opposite direction to that
expected. In declining order, the following scales (5 out of 7) revealed statistically significant differences: Clear Goals
and Standards; the General scale; Appropriate Workload; Good Teaching; and Independence. Moreover, when the assessment mode
was considered, also the Appropriate Assessment scale demonstrated significant differences between the five research conditions.
Moreover, the same teaching/learning environments led to diverse students’ perceptions. While the perceptions of lecture-taught
students were focused and concordantly positive, students’ course experiences with student-activating methods were widely
varied and both extremely positive and negative opinions were present. Students’ arguments in favour of the activating setting
were the variety of teaching methods, the challenging and active nature of the assignments and the joys of collaborative work
in teams, whereas students expressed dissatisfaction with the perceived lack of learning gains, the associated time pressure
and workloads, and the (exclusive) use of collaborative assignments and related group difficulties. 相似文献

The study investigated how well report card grades communicate to students and parents that state educational standards are
being met, standards that are objectively measured by infrequently administered mandated assessments. Data sources were report
card grades and external assessment scores for 2006–09 for Ontario Canada. The information that parents and students received
about student performance from report cards and external assessments were similar (r
s
= .47) to the r = .40–.60 range previously reported. Teachers assigned higher grades than external assessments warranted, even after a major
source of construct irrelevant variance in report card grades (teacher ratings on multiple scales measuring student effort
and school commitment) was controlled. The relationship of grades to assessment scores was robust across genders, school district
types (Public versus Catholic) and language (English and French). Agreement of assessments was higher for grade 6 than for
grade 3 and for Writing than for Reading or Mathematics. Report cards provided information about students’ future achievement
that was accurate and delivered up to 2 years prior to the administration of external assessments. Seventy to 80% of students
who reached the provincial achievement standard on one or both prior report cards were successful on the subsequent external
assessment, compared to 30–50% of students who failed to meet the report card standard at least once. 相似文献

Two studies examined the effects of four types of teachers’ evaluative feedback on Chinese students’ self-efficacy in English
vocabulary acquisition. In Study 1, a random sample of Grade 8 students (N = 79) learned prefixes and received either formative or summative feedback after failure in test. The results showed that
students who received summative feedback showed a larger decrease in their self-efficacy than those who received formative
feedback. In Study 2, a random sample of Grade 7 students (N = 77) went through similar procedures as in Study 1 except that students received either self-referenced or norm-referenced
feedback. The results showed that self-referenced feedback was more beneficial to students’ self-efficacy than norm-referenced
feedback. The influences of teachers’ evaluation and feedback on students’ self-efficacy are discussed. 相似文献

The construct of identity has been used widely in mathematics education in order to understand how students (and teachers)
relate to and engage with the subject (Kaasila, 2007; Sfard & Prusak, 2005; Boaler, 2002). Drawing on cultural historical activity theory (CHAT), this paper adopts Leont’ev’s notion of leading activity in order to explore the key ‘significant’ activities that are implicated in the development of students’ reflexive understanding
of self and how this may offer differing relations with mathematics. According to Leont’ev (1981), leading activities are those which are significant to the development of the individual’s psyche through the emergence
of new motives for engagement. We suggest that alongside new motives for engagement comes a new understanding of self—a leading identity—which reflects a hierarchy of our motives. Narrative analysis of interviews with two students (aged 16–17 years old) in post-compulsory
education, Mary and Lee, are presented. Mary holds a stable ‘vocational’ leading identity throughout her narrative and, thus,
her motive for studying mathematics is defined by its ‘use value’ in terms of pursuing this vocation. In contrast, Lee develops
a leading identity which is focused on the activity of studying and becoming a university student. As such, his motive for
study is framed in terms of the exchange value of the qualifications he hopes to obtain. We argue that this empirical grounding
of leading activity and leading identity offers new insights into students’ identity development. 相似文献

This study contributes to research that characterises the affective learning that is evoked and taken on by students in response
to their perceptions of their contextual learning environments. Interview-discussions were held with lecturers of both introductory
and higher-level physics courses (n = 3) concerning how they formulated their patterns of teaching in terms of a particular conceptual framing that they considered
to best optimize making learning possible. Subsequently their students (n = 212) were asked with written questions, and some select follow-up interview-discussions, to describe what they expected
from ‘a good physics lecturer’. The relationships between these two things—the lecturer’s crafting of practice and the students’
expectations of quality teaching—were investigated. Results show that students’ expectations tend to match their lecturers’
practice, indicating that students are strongly influenced by a contextually based appreciation of ‘good’ teaching. 相似文献

This exploratory study examines the learning beliefs of high and low achieving, low-income Mexican-American students. Semi-structured
interviews were conducted with 11 ninth grade students. The qualitative analysis shows that students’ perceptions of their
teachers’ expectations of a “good” student or a “not so good” student did not differ along achievement lines. However, the
students’ perceptions about what it means to be a good student differentiated the low-achievers from the high-achievers. This
study’s findings may be used to inform educators about Mexican-American students’ orientation towards school and learning,
in hopes for creating more equitable educational settings where all students achieve to their fullest potential.

We report the results of a study with 30 teachers designed to examine the effects of teacher knowledge on the achievement
of struggling readers. We worked with teachers of grades three, four, and five during a 10-day intervention focused on literacy
instruction and related linguistic knowledge, and we assessed their students’ learning across the year. Hierarchical models
of student outcomes indicated that lower-performing students in intervention classrooms showed significantly higher levels
of performance at year end on all literacy measures, compared with their peers in control classrooms (n = 140). In addition, teacher’s linguistic knowledge was related to improved student performance, regardless of condition.
Additional analyses including all students (n = 718) indicated that benefits for the lower performing students in intervention classrooms were shared by their classmates,
but to a more limited extent. 相似文献
