During their years of schooling, students develop perceptions about learning and teaching, including the ways in which teachers
impact on their learning experiences. This paper presents student perceptions of teacher pedagogy as interpreted from a study
focusing on students' experience of Year 7 science. A single science class of 11 to 12 year old students and their teacher
were monitored for the whole school year, employing participant observation, and interviews with focus groups of students,
their teacher and other key members of the school. Analysis focused on how students perceived the role of the teacher's pedagogy
in constructing a learning environment that they considered conducive to engagement with science learning. Two areas of the
teacher's pedagogy are explored from the student perspective of how these affect their learning: instructional pedagogy and
relational pedagogy. Instructional pedagogy captures the way the instructional dialogue developed by the teacher drew the students into the learning process and enabled
them to “understand” science. How the teacher developed a relationship with the students is captured as relational pedagogy, where students said that they learned better when teachers were passionate in their approach to teaching, provided a supportive
learning environment and made them feel comfortable. The ways in which the findings support the direction for the middle years
and science education are considered. 相似文献

Adopting the concept that “decisions can be seen as argument-driven actions,” the purpose of this study was to apply the argumentation
structure raised by Stephen Toulmin (1958) to capture two science teachers' instructional decision-making mechanisms in their
teaching practices. The two case teachers were chosen because of their close estimations of their students' achievement outcomes
and both were in their transition stages from competent teachers to proficient ones. A science teaching observation coding
schedule (STOCS) was designed to be used in classroom observations, and all these quantitative data were collected to be converted
into four issues for the two teachers to justify their ways of teaching. A semi-structure interview was conducted to analyze
why and how these two case teachers made their instructional decisions. The results indicate that although they knew that
their students could not fully understand what they taught in the class, their teaching strategies were still teacher-dominated
modes. What really influenced their instructional decisions included external context factors (e.g., examination pressure,
subject contents, limited time and classroom management) and internal experiential factors (e.g., personal educated experiences,
beliefs and understandings of constructivism and inquiry). Finally, the authors suggest that science teachers' instructional
decision making mechanisms can be appropriately represented by case teachers' argumentations structure. 相似文献

This study investigates the potential of enhancing students' learning of difficult science concepts by exploring the interaction
between teachers' four different instructional approaches and students' four different learning preference styles. Students'
immediate performance and their retention for learning of buoyancy concepts serve to examine the effects, using the concept
of “buoyancy,” which has been classified as a difficult concept because it is at a higher hierarchical level and involves
the understanding of both matter and process. Results indicate that students' post-test scores were significantly affected
by both the types of instruction and students' learning preference styles; while students' retention test scores were significantly
affected by the types of instructions. Moreover, this study does not support that matching teaching style with students' learning
preference would make students' learning more effective. Nevertheless, because procedural learning preference styles (QB-learning
preference) students performed better on the retention test than other learning preference styles students, it indicates the
possibility that procedural learners are more efficient than others for learning such higher hierarchical and difficult concepts,
regardless of the types of instruction students receive. 相似文献

Emerging from a human constructivist view of learning and a punctuated model of conceptual change, these studies explored
differences in the structural complexity and content validity of knowledge about prehistoric life depicted in concept maps
by learners ranging in age from approximately 10 to 20 years. Study 1 (cross-age) explored the frequencies of concepts, relationships,
levels of hierarchy, branching, and cross-links in concept maps drawn by students in grades 5, 8, 11, 13, and 14. The results
provide some support for a punctuated model of conceptual change. Study 2 (longitudinal) explored the same frequencies on
repeated occasions among students enrolled in a college course on prehistoric life, and documented the shift in frequencies
of “novice” and “expert” concepts occurring during the semester. The results suggest that college students engage in much
restructuring of their knowledge frameworks during the period of a semester. Together, the two studies raise questions about
common classroom practices that encourage the rote learning of biology and geology concepts at all levels. 相似文献

Productive failure in mathematical problem solving 总被引：1，自引：0，他引：1

This paper reports on a quasi-experimental study comparing a “productive failure” instructional design (Kapur in Cognition
and Instruction 26(3):379–424, 2008) with a traditional “lecture and practice” instructional design for a 2-week curricular unit on rate and speed. Seventy-five,
7th-grade mathematics students from a mainstream secondary school in Singapore participated in the study. Students experienced
either a traditional lecture and practice teaching cycle or a productive failure cycle, where they solved complex problems
in small groups without the provision of any support or scaffolds up until a consolidation lecture by their teacher during
the last lesson for the unit. Findings suggest that students from the productive failure condition produced a diversity of
linked problem representations and methods for solving the problems but were ultimately unsuccessful in their efforts, be
it in groups or individually. Expectedly, they reported low confidence in their solutions. Despite seemingly failing in their
collective and individual problem-solving efforts, students from the productive failure condition significantly outperformed
their counterparts from the lecture and practice condition on both well-structured and higher-order application problems on
the post-tests. After the post-test, they also demonstrated significantly better performance in using structured-response
scaffolds to solve problems on relative speed—a higher-level concept not even covered during instruction. Findings and implications
of productive failure for instructional design and future research are discussed. 相似文献

A science teacher and her mentor reflect on their participation in the Learning Research Cycle, a professional learning model
that bridges research and practice in both university and public school contexts. Teachers do scientific research in scientists’
laboratories, then bridge their scientific experiences with the design of new classroom learning environments and teacher-driven
educational research projects. Science students do scientific research via their teachers’ lessons that bridge laboratory
research with classroom learning. Scientists and educational researchers bridge their research interests to create new questions
centered on teaching and learning in authentic science learning environments. The authors engaged in this qualitative inquiry
present their perspectives on “what goes on,” “what we have learned,” and “what it means to the larger community.” 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

This forum discussion focuses on seven themes drawn from Sonya’s fascinating paper: the terminology of “cogenerative dialogues,”
the roles of participants and their power relations within such dialogues, the use of metaphor and analogy in the paper, science
and science education for all students, the ways in which students’ expectations about learning change in innovative classrooms,
teacher research and the “theory-practice gap,” and the tension between conducting cogenerative dialogues with individual
students or with whole classes. These themes by no means exhaust the ideas in Sonya’s paper, but we feel that they have allowed
us to explore the classroom research she reports, and to extend our discussion beyond the paper to explore some of these themes
more broadly. 相似文献

The potential of informal sources of science learning to supplement and interact with formal classroom science is receiving
increasing recognition and attention in the research literature. In this study, a phenomenographic approach was used to determine
changes in levels of understanding of 27 grade 7 primary school children as a result of a visit to an interactive science
centre. The results showed that most students did change their levels of understanding of aspects of the concept “sound”.
The study also provides information which will be of assistance to teachers on the levels of understanding displayed by students
on this concept.

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

In this article we analyze the dialogic learning of one pair of students in order to investigate how these students cope with a collaborative learning situation in the classroom. Our aim is to substantiate the claims that not only are young students (8 year olds) capable of solving mathematical problems collaboratively, but that they also take an active role in regulating their collaborative learning activities. More specifically, our claim is that children appear to apply constructs of “mathematical level raising”, “social interaction” and “division of time” to steer their own collaborative learning and that they are rather successful in balancing these three aspects. The analysis is exploratory, but this new perspective on collaborative learning is relevant theoretically and consequential for classroom practice. 相似文献

This forum considers argumentation as a means of science teaching in South African schools, through the integration of indigenous
knowledge (IK). It addresses issues raised in Mariana G. Hewson and Meshach B. Ogunniyi’s paper entitled: Argumentation-teaching
as a method to introduce indigenous knowledge into science classrooms: opportunities and challenges. As well as Peter Easton’s:
Hawks and baby chickens: cultivating the sources of indigenous science education; and, Femi S. Otulaja, Ann Cameron and Audrey
Msimanga’s: Rethinking argumentation-teaching strategies and indigenous knowledge in South African science classrooms. The
first topic addressed is that implementation of argumentation in the science classroom becomes a complex endeavor when the
tensions between students’ IK, the educational infrastructure (allowance for teacher professional development, etc.) and local
belief systems are made explicit. Secondly, western styles of debate become mitigating factors because they do not always
adequately translate to South African culture. For example, in many instances it is more culturally acceptable in South Africa
to build consensus than to be confrontational. Thirdly, the tension between what is “authentic science” and what is not becomes
an influencing factor when a tension is created between IK and western science. Finally, I argue that the thrust of argumentation
is to set students up as “scientist-students” who will be considered through a deficit model by judging their habitus and
cultural capital. Explicitly, a “scientist-student” is a student who has “learned,” modeled and thoroughly assimilated the
habits of western scientists, evidently—and who will be judged by and held accountable for their demonstration of explicit
related behaviors in the science classroom. I propose that science teaching, to include argumentation, should consist of “listening
carefully” (radical listening) to students and valuing their language, culture, and learning as a model for
“science for all”. 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 describe a workshop in which 10 teachers from 10 schools, located in central Israel, participated in the development of
alternative assessment tools in the context of implementing a new science curriculum for senior high-school students, namely
“Science for All” (an STS type curriculum). In order to assist a group of teachers (who began teaching the “Science for All”
program) in both teaching and assessment strategies, it was decided that the Department of Science Teaching at the Weizmann
Institute of Science would sponsor a workshop for them. An evaluation study was conducted during the workshop and at its completion.
The main goal of the study was to evaluate the outcomes of the workshop and to determine whether its objectives were attained.
The research tools consisted of (a) an attitude questionnaire administered to participating teachers, (b) structured interviews
with the teachers, (c) structured interviews with students, and (d) an attitude questionnaire administered to the students.
Based on the results of the questionnaires and the interviews, it seems that all the teachers who participated in the workshop
gained self-confidence in using the teaching strategies and assessment methods of this new interdisciplinary curriculum. The
interviews with students revealed that their active involvement in their own assessment improved their sense of responsibility
for their achievements. The variety of assignments enabled them to be at their best with certain assignments and to succeed
less with others. In conclusion, we found that running a new interdisciplinary curriculum requires a professional development
program that will stimulate teachers’ creativity and diversify the instructional strategies that they use in the classroom.
Such skills should improve their ability to understand the goals, strategies, and rationale of the curriculum, as well as
their students’ learning difficulties. 相似文献

Every aspect of teaching, including the instructional method, the course content, and the types of assessments, is influenced
by teachers’ attitudes and beliefs. Teacher education programs play an important role in the development of beliefs regarding
teaching and learning. The purpose of the study was to document pre-service teachers’ views on science, scientists, and science
teaching as well as the relations between these views and the offered courses over several years spent in an elementary science
teacher training program. The sample consisted of 145 pre-service elementary science teachers who were being trained to teach
general science to students in the 6th through 8th grades. The research design was a cross-sectional study. Three different
instruments were used to collect the data, namely, the “Draw a Scientist Test”, “Draw a Science Teacher Test”, and “Students’
Views about Science” tests. The elementary science teacher training program influenced pre-service science teachers’ views
about science, scientists and science teaching to different degrees. The most pronounced impact of the program was on views
about science teaching. Participants’ impressions of science teaching changed from teacher-centered views to student-centered
ones. In contrast, participants’ views about scientists and science did not change much. This result could be interpreted
as indicating that science teacher training programs do not change views about science and scientists but do change beliefs
regarding teaching science. 相似文献

There is a growing consensus that traditional instruction in basic science courses, in institutions of higher learning, do
not lead to the desired results. Most of the students who complete these courses do not gain deep knowledge about the basic
concepts and develop a negative approach to the sciences. In order to deal with this problem, a variety of methods have been
proposed and implemented, during the last decade, which focus on the “active learning” of the participating students. We found
that the methods developed in MIT and NCSU were fruitful and we adopted their approach. Despite research-based evidence of
the success of these methods, they are often met by the resistance of the academic staff. This article describes how one institution
of higher learning organized itself to introduce significant changes into its introductory science courses, as well as the
stages teachers undergo, as they adopt innovative teaching methods. In the article, we adopt the Rogers model of the innovative-decision
process, which we used to evaluate the degree of innovation adoption by seven members of the academic staff. An analysis of
interview and observation data showed that four factors were identified which influence the degree innovation adoption: (1)
teacher readiness to seriously learn the theoretical background of “active learning”; (2) the development of an appropriate
local model, customized to the beliefs of the academic staff; (3) teacher expertise in information technologies, and (4) the
teachers’ design of creative solutions to problems that arose during their teaching. 相似文献

This article presents a critical review and analysis of key studies that have been done in science education and other areas
on the effects and effectiveness of using diagrams, graphs, photographs, illustrations, and concept maps as adjunct visual aids in the learning of scientific-technical content. It also summarizes and reviews those studies that have students draw diagrams,
graphs, maps, and charts to express their understandings of the concepts and relationships that are present in the text they
read or/and empirical data provided (i.e., student-generated adjunct visual productions). In general, the research and theory on instructional aids is fragmented and somewhat unsystematic with several flaws and
a number of key uncontrolled variables, which actually suppress and mask effects in the studies that have been done. The findings
of these studies are compared to relevant literature and empirical research and findings in the areas of cognitive psychology,
computer science, neuroscience, and artificial intelligence that help to clarify many of the inconsistencies, contradictions,
and lack of effects found for visual (e.g., diagrams and graphs) instructional aids in the science education literature currently
and in the past 20 years. A model and a set of criteria and goals for improving research in this area is then described, as
visuals are a first step in the process of learning formal (scientific) models, which are most often visually represented.
Understanding how students learn formal models is one the outstanding research challenges in the next 20 years, both within
and outside of science education. 相似文献

In adult literacy programs today, well-intentioned but inadequately prepared volunteer tutors are being matched with learning
disabled adult students without the benefit of receiving training from experts in the field of language/learning disabilities.
The collaboration of adult literacy providers and learning specialists is obviously the most resourceful, yet most untried,
solution to a problem that is plaguing volunteer-based programs across the country: meeting the needs of learning disabled
adults. One adult literacy program—READ/San Diego of the San Diego Public Library—recognized that its volunteer tutors needed
training in special instructional methods to teach adults who evidence learning disabilities. Accordingly, the program’s administrator
obtained the services of specialists to develop a learning disabilities tutor-training module. This article (1) presents an
overview of preservice volunteer training at READ/San Diego; (2) discusses informal assessment procedures that help identify
possible language/learning disabilities in adults and provide valuable information for instructional planning; and (3) describes
selected multisensory teaching techniques designed especially for adults who “learn differently.” 相似文献
