The challenge that we address concerns teachers’ shifts toward student-centered instruction. We report on a yearlong professional
development study in which two United States elementary school teachers engaged in a teaching experiment, as described by
Steffe and Thompson (in: Lesh and Kelly (eds) Research on design in mathematics and science education, 2000). The teaching
experiment involved close mathematical interactions with a pair of students after school, in the context of solving fractions
tasks. By conducting a teaching experiment, we anticipated that each teacher would have more opportunity to develop insight
into students’ mathematics. We also anticipated that these insights would influence the teachers’ classroom practice, even
without explicit support for such a shift. Indeed, the teachers found that they began asking more probing questions of their
students and spending more time listening to students’ explanations, but shifts to classroom practice were limited by constraining
factors such an inflexible curriculum. 相似文献

The influence of video clubs on teachers’ thinking and practice 总被引:1,自引:0,他引:1

This article examines a model of professional development called “video clubs” in which teachers watch and discuss excerpts
of videos from their classrooms. We investigate how participation in a video club influences teachers’ thinking and practice
by exploring three related contexts: (a) teachers’ comments during video-club meetings, (b) teachers’ self-reports of the
effects of the video club, and (c) teachers’ instruction across the year. Data analysis revealed changes in all three contexts.
In the video-club meetings, teachers paid increased attention to student mathematical thinking over the course of the year.
In interviews, teachers reported having learned about students’ mathematical thinking, about the importance of attending to
student ideas during instruction, and about their school’s mathematics curriculum. Finally, shifts were also uncovered in
the teachers’ instruction. By the end of the year, teachers increasingly made space for student thinking to emerge in the
classroom, probed students’ underlying understandings, and learned from their students while teaching. 相似文献

In the multilingual mathematics classroom, the assignment for teachers to scaffold students by means of instruction and guidance in order to facilitate language progress and learning for all is often emphasized. In Sweden, where mathematics education is characterized by a low level of teacher responsibility for students’ performance, this responsibility is in part passed on to students. However, research investigating the complexity of relations between mathematics teaching and learning in multilingual classrooms, as well as effect studies of mathematics teaching, often take the existence of teachers’ responsibility for offering specific content activities for granted. This study investigates the relations between different aspects of responsibility in mathematics teaching and students’ performance in the multilingual mathematics classroom. The relationship between different group compositions and how the responsibility is expressed is also investigated. Multilevel structural equation models using TIMSS 2003 data identified a substantial positive influence on mathematics achievement of teachers taking responsibility for students’ learning processes by organizing and offering a learning environment where the teacher actively and openly supports the students in their mathematics learning, and where the students also are active and learn mathematics themselves. A correlation was also revealed between group composition, in terms of students’ social and linguistic background, and how mathematics teaching was performed. This relationship indicates pedagogical segregation in Swedish mathematics education by teachers taking less responsibility for students’ learning processes in classes with a high proportion of students born abroad or a high proportion of students with low socio-economic status. 相似文献

In the United States today, urban schools serve the majority of high-poverty and high minority populations including large
numbers of Hispanic students. While many Hispanic students perform below grade level in middle school science, the science
teaching community as a whole is lacking elements of diversity as teachers struggle to meet the needs of all learners. Researchers
have recognized that science teacher effectiveness, one consequence of self-efficacy among teachers, is associated with future
science achievement and science-related careers of their students. This qualitative study explores how three science teachers’
effectiveness in the classroom impacts students’ science self-efficacy beliefs at one urban middle school. Hispanic students
were the focus of this investigation due to demographics and history of underperformance within this district. Teachers’ perspectives,
as well as outside observer evaluations of instructional strategies and classroom climates were triangulated to explore dynamics
that influence students’ interests and motivation to learn science using a framework to link teachers’ sense of efficacy (focusing
on student outcomes). Findings suggest the impact teacher effectiveness can have on student outcomes, including strengthened
student science self-efficacy and increased science achievement. Building awareness and support in teachers’ sense of efficacy,
as well as developing respectful and supportive relationships between educator/facilitator and pupil during the transition
to middle school may construct permanence and accomplishment for all in science. 相似文献

For an educational reform to succeed, teachers need to adjust their perceptions to the reform’s new curricula and strategies
and cope with new content, as well as new teaching and assessment strategies. Developing students’ scientific literacy through
context-based chemistry and higher order thinking skills was the framework for establishing a new chemistry curriculum for
Israeli high school students. As part of this endeavor, we developed the Taste of Chemistry module, which focuses on context-based chemistry, chemical understanding, and higher order thinking skills. Our research
objectives were (a) to identify the challenges and difficulties chemistry teachers faced, as well as the advantages they found,
while teaching and assessing the Taste of Chemistry module; and (b) to investigate how they coped with teaching and assessing thinking skills that include analyzing data from
graphs and tables, transferring between multiple representations and, transferring between chemistry understanding levels.
Research participants included eight teachers who taught the module. Research tools included interviews, classroom observations,
teachers-designed students’ assignments, and developers-designed students’ assignments. We documented different challenges
teachers had faced while teaching the module and found that the teachers developed different ways of coping with these challenges.
Developing teachers’ assessment knowledge (AK) was found to be the highest stage in teachers’ professional growth, building
on teachers’ content knowledge (CK), pedagogy knowledge (PK), and pedagogical-content knowledge (PCK). We propose the use
of assignments designed by teachers as an instrument for determining their professional growth. 相似文献

The aim of the reported study was to explore how science teachers made sense of their roles and responsibilities in teaching
and assessing science coursework. The focus was on the teacher assessment, the feedback that teachers gave to students and,
how they perceived their role when they taught and assessed students’ science coursework reports. The research methodology
included observation of science lessons, collection of marked students’ reports and two interviews with each of the nine participant
teachers. Two cases of teachers are considered as representative of the participant teachers and their perceptions and practices
are compared and contrasted. Teachers either adopted the role of the examiner or combined the role of the teacher with that
of examiner. They distinguished marking of science theory exercises from marking of coursework and, teaching theory from teaching
investigations, on the basis that the grade they assigned to coursework contributed to the total grade for external exams.
A key conclusion is that teaching and assessment of science coursework need to re-focus on learning. The study calls for changes
in public policy for summative assessment to place more reliance on teachers’ assessments and secondly, for changes in school
practices in formative assessment for teachers to support students to learn in the case of science coursework. 相似文献

The impact of No Child Left Behind (NCLB) mandated state science assessment on elementary teachers’ beliefs about teaching
science and their classroom practice is relatively unknown. For many years, the teaching of science has been minimized in
elementary schools in favor of more emphasis on reading and mathematics. This study examines the dynamics of bringing science
to the forefront of assessment in elementary schools and the resulting teacher belief and instructional shifts that take place
in response to NCLB. Results indicated that teachers’ beliefs about teaching science remained unchanged despite policy changes
mandated in NCLB. Teacher beliefs related to their perceptions of what their administrators and peer groups’ think they should
be doing influenced their practice the most. Most teachers reported positive feelings and attitudes about science and reported
that their students had positive feelings and attitudes about science; however, teachers reported teaching science less as
a result of NCLB. Implications for elementary science education reform and policy are discussed. 相似文献

Culturally responsive science teaching is using knowledge about the culture and life experiences of students to structure
learning that is conducive to their needs. Understanding what teachers need to prepare them to be culturally responsive is
a matter of continuous debate. As the focus of multicultural education ventures farther away from its roots, advocating the
civil rights of historically oppressed groups, concerns about the gravity of racial inequity on schooling continues. How will
this shift in focus influence teachers’ capacity to accommodate students’ needs resulting from racial inequities in this society,
particularly African American students? What knowledge is essential to their effectiveness? This qualitative study examined
the instructional practices of two effective middle school science teachers deemed culturally responsive by their administrator
on the basis of classroom observations, students’ responses and standardized assessment results. Both teachers’ classrooms
consisted primarily of African American students. Grounded theory was used to analyze the teachers’ beliefs and practices
in order to identify existing commonalties. Critical race theory was used to identify whether there was any influence of the
students’ racial identities on the teachers’ beliefs and practices. The analysis reveals that the teachers’ beliefs and practices
were informed by their critical awareness of social constraints imposed upon their African American students’ identities.
These findings communicate the significance of sociocultural awareness to informing the teachers’ instruction, as well as
their strategies for managing the varying dynamics occurring in their classrooms. It can be deduced from the findings that
an understanding of racial inequities is crucial to the development of sociocultural awareness, and is the foundation for
the culturally responsive dispositions and practices of these middle school science teachers. 相似文献

Current reform-driven mathematics documents stress the need for teachers to provide learning environments in which students
will be challenged to engage with mathematics concepts and extend their understandings in meaningful ways (e.g., National
Council of Teachers of Mathematics, 2000, Curriculum and evaluation standards for school mathematics. Reston, VA: The Council). The type of rich learning contexts that are envisaged by such reforms are predicated on a number
of factors, not the least of which is the quality of teachers’ experience and knowledge in the domain of mathematics. Although
the study of teacher knowledge has received considerable attention, there is less information about the teachers’ content
knowledge that impacts on classroom practice. Ball (2000, Journal of Teacher Education, 51(3), 241–247) suggested that teachers’ need to ‘deconstruct’ their content knowledge into more visible forms that would
help children make connections with their previous understandings and experiences. The documenting of teachers’ content knowledge
for teaching has received little attention in debates about teacher knowledge. In particular, there is limited information
about how we might go about systematically characterising the key dimensions of quality of teachers’ mathematics knowledge
for teaching and connections among these dimensions. In this paper we describe a framework for describing and analysing the
quality of teachers’ content knowledge for teaching in one area within the domain of geometry. An example of use of this framework
is then developed for the case of two teachers’ knowledge of the concept ‘square’. 相似文献

The study identified two dimensions of teacher self-efficacy and practices and five dimensions of students’ mathematics self-efficacy
and sought to determine the extent to which teacher characteristics and practices can enhance secondary school students’ self-efficacy.
Data were collected from 13,173 students in 193 teachers’ classrooms from 141 schools in the 10 districts of Lake Victoria
Region of Kenya. Two-level hierarchical linear model revealed that teachers’ frequent use of mathematics homework, their level
of interest and enjoyment of mathematics, as well as their ability and competence in teaching mathematics were found to play
a key role in promoting students’ mathematics self-efficacy. Teachers’ ability and competence in teaching were also found
to be effective in narrowing the gender gap in students’ self-confidence and competence in mathematics. The study recommends
that teacher training colleges emphasize such teacher practices and values in order to enhance students’ mathematics self-efficacy,
reduce their level of anxiety and fear of mathematics, and consequently, enhance their achievement in mathematics. Professional
development opportunities should also be made available to in-service teachers to continually update their knowledge and skills
and develop new strategies for teacher effectiveness. 相似文献

A survey instrument using everyday teaching scenarios was developed to measure teacher conceptions of inquiry. Validity of
the instrument was established by comparing responses for a group of secondary teachers to narrative writing and group discussion.
Participating teachers used only three of the five essential features of inquiry detailed in the standards documents (NRC
2000) when expressing their ideas of classroom inquiry. The features of ‘evaluating explanations in connection with scientific
knowledge’ and ‘communicating explanations’ were rarely mentioned. These missing components indicate a gap between the teachers’
conceptions of inquiry and the ideals of the reform movement. 相似文献

The purpose of this paper is to contribute to the debate about how to tackle the issue of ‘the teacher in the teaching/learning
process’, and to propose a methodology for analysing the teacher’s activity in the classroom, based on concepts used in the
fields of the didactics of mathematics as well as in cognitive ergonomics. This methodology studies the mathematical activity
the teacher organises for students during classroom sessions and the way he manages1 the relationship between students and mathematical tasks in two approaches: a didactical one [Robert, A., Recherches en Didactique
des Mathématiques 21(1/2), 2001, 7–56] and a psychological one [Rogalski, J., Recherches en Didactique des Mathématiques 23(3),
2003, 343–388]. Articulating the two perspectives permits a twofold analysis of the classroom session dynamics: the “cognitive
route” students are engaged in—through teacher’s decisions—and the mediation of the teacher for controlling students’ involvement
in the process of acquiring the mathematical concepts being taught. The authors present an example of this cross-analysis
of mathematics teachers’ activity, based on the observation of a lesson composed of exercises given to 10th grade students
in a French ‘ordinary’ classroom. Each author made an analysis from her viewpoint, the results are confronted and two types
of inferences are made: one on potential students’ learning and another on the freedom of action the teacher may have to modify
his activity. The paper also places this study in the context of previous contributions made by others in the same field. 相似文献

Science teachers from secondary schools in Tanzania were offered an in-service arrangement to prepare them for the integration
of technology in a student-centered approach to science teaching. The in-service arrangement consisted of workshops in which
educative curriculum materials were used to prepare teachers for student-centered education and for the use and application
of Microcomputer Based Laboratories (MBL)—a specific technology application for facilitating experiments in science education.
Quantitative and qualitative data were collected to study whether the in-service arrangement impacted teacher learning. Teacher
learning was determined by three indicators: (1) the ability to conduct MBL-supported student centered science lessons, (2)
teachers’ reflection on those lessons and (3) students’ perceptions of the classroom environment. The results of the research
indicate that the teachers’ were able to integrate MBL in their science lessons at an acceptable level and that they were
able to create a classroom environment which was appreciated by their students as more investigative and open-ended. 相似文献

Advocates of constructivist science recommend that school science begins with children’s own constructions of reality. This
notion of the way in which students’ knowledge of science grows is closely paralleled by recent research on teachers’ knowledge.
This paper draws on case study evidence of teachers’ work to show how two experienced teachers’ attempts to develop alternative
ways of teaching science involved reframing their previous patterns of understanding and practice. Two alternative interpretations
of the case study evidence are offered. One interpretation, which focuses on identifying gaps in the teachers’ knowledge of
science teaching, leads to theconstructivist paradox. The second interpretation explores theconstructivist parallel, an approach which treats the process of teachers’ knowledge growth with the same respect as constructivists treat students’
learning of science. This approach, the authors argue, is not only more epistemologically consistent but also opens up the
possibilities of helping teachers lead students towards a constructivist school science.

This collective case study reports on an investigation into the relationship between mathematics teachers’ beliefs and their
classroom practices, namely, how they organized their classroom activities, interacted with their students, and assessed their
students’ learning. Additionally, the study examined the pervasiveness of their beliefs in the face of efforts to incorporate
reform-oriented classroom materials and instructional strategies. The participants were five high school teachers of ninth-grade
algebra at different stages in their teaching career. The qualitative analysis of the data revealed that in general beliefs
were very influential on the teachers’ daily pedagogical decisions and that their beliefs about the nature of mathematics
served as a primary source of their beliefs about pedagogy and student learning. Findings from the analysis concur with previous
studies in this area that reveal a clear relationship between these constructs. In addition, the results provide useful insights
for the mathematics education community as it shows the diversity among the inservice teachers’ beliefs (presented as hypothesized
belief models), the role and influence of beliefs about the nature of mathematics on the belief structure and how the teachers
designed their instructional practices to reflect these beliefs. The article concludes with a discussion of implications of
teacher education. 相似文献

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2
classrooms in rural school districts. The research specifically examined changes in (a) teachers’ content knowledge in science;
(b) teachers’ self-efficacy related to teaching science; (c) classroom instructional time allotted to science; and (d) instructional
strategies used in science. The study also investigated contextual factors contributing to or hindering changes in science
instruction. Data sources included a teacher survey, a self-efficacy assessment, content knowledge tests, interviews, and
classroom observations. After one year in the program, teachers showed increased content knowledge and self-efficacy in teaching
science; they spent more instructional time on science and began using different instructional strategies. Key contextual
factors included curricular demands, resources, administrative support, and support from other teachers. 相似文献

How teachers “care” for students is a well-established line of inquiry in educational research, but the ways such “care” may
function as symbolic violence have received scant attention. In this ethnographic investigation of classroom disciplinary
interactions, the characteristics and functions of preservice teachers’ care discourses are examined. By translating deficit
discourses into expressions of praise for students’ nonacademic talents, the participants’ rhetoric of care effectively shifts
blame for failure from teacher to student. The preservice teachers’ expressions of care also function to veil the power being
produced in such rhetoric, to frame the teacher as victim when said care is rejected, and to reverse the carer/cared-for dynamic
when teachers’ attempts to inspire academic progress are unsuccessful. Implications for teacher education and teacher development
are provided as are suggestions for how to recognize and implement more authentic forms of care. 相似文献

We investigated relationships among elementary teachers’ reading-related content knowledge (knowledge of literature and phonology),
their philosophical orientation toward reading instruction, their classroom practice, and their students’ learning. Correlations
showed little relationship between instructional philosophy and content knowledge, and little relationship between instructional
philosophy and classroom practice. However, relationships emerged between content knowledge and instruction, and between kindergarten
teachers’ phonological knowledge and their students’ reading achievement. We recommend that the recent focus on teacher’s
disciplinary knowledge be broadened to include teachers of beginning reading and that teachers be afforded opportunities to
develop the necessary knowledge base to teach reading effectively. 相似文献
