In this article we describe our engagement in self-study as part of an examination of design-based research for education. We focus on graduate-level online teacher education as an example of how self-study provided a means of examining deeply our teaching and our roles as teacher and designer in the learning environment. We posit that online learning environments are particularly well suited for self-study to enhance design perspectives because the interactions between teacher and students are informed by personal context and mediated by technological tools. The graduate students in our courses were teacher leaders in literacy or mathematics who were learning how to support professional development for other teachers. Throughout our self-study research we found ourselves drawing upon our previous design research experiences, which aided our ability to engage in self-study: We were part of the classroom system, focusing on our roles within the teaching and learning process as designers of the online learning environment. Three key design principles resulted from our self-study process: focusing on systems of learning and teaching, designing pedagogical tools and products, and using iterative processes. Engaging in self-study enhanced our understanding and implementation of synchronous online instruction, particularly regarding our use of technological tools to enhance student learning and support learning communities. 相似文献

In many countries around the world, there has been an increasing emphasis on improving science education. Recent reform efforts in the USA call for teachers to integrate scientific and engineering practices into science teaching; for example, science teachers are asked to provide learning experiences for students that apply crosscutting concepts (e.g., patterns, scale) and increase understanding of disciplinary core ideas (e.g., physical science, earth science). Engineering practices and engineering design are essential elements of this new vision of science teaching and learning. This paper presents a research study that evaluates the effects of an engineering design-based science curriculum on student learning and attitudes. Three middle school life science teachers and 275 seventh grade students participated in the study. Content assessments and attitude surveys were administered before and after the implementation of the curriculum unit. Statewide mathematics test proficiency scores were included in the data analysis as well. Results provide evidence of the positive effects of implementing the engineering design-based science unit on student attitudes and learning. 相似文献

Among the initiatives of the Maryland Collaborative for Teacher Preparation (MCTP) is a summer research internship program
that places preservice middle grades teachers in extended collaboration with professional mathematicians, scientists, and
educators engaged in research and curriculum development activities. We describe the MCTP internship program including the
rationale for and structural features of the program. We also highlight the effects of the internship experience on preservice
teachers' conceptions of and beliefs about the nature and processes of mathematics and science, and the teaching of mathematics
and science. Our findings suggest that the internship experience is a fundamentally significant life experience for preservice
teachers. Furthermore, internships have the potential for realizing reform in mathematics and science education; that is,
preservice teachers who have participated in MCTP internships intend to bring a holistic, conceptually oriented view of mathematics
and science to their classrooms. The paper concludes with a summary of ongoing programmatic and logistical challenges of the
MCTP internship program.

We report on the initial attempts at evaluating at scale a particular technological/curricular innovation that enables more students to develop deeper knowledge. The methods, issues, and findings of the current pilot experiment speak not only to the success of SimCalc MathWorlds, the focus of our research program, but also to the evaluation at scale of a broad class of representationally innovative technologies and to the merit of long-term investment in design-based research. In particular, we present conditions and findings from a completed pilot experiment involving 21 seventh-grade mathematics teachers from Texas. Pilot outcomes suggest that (a) innovative representational technologies can have an important impact on student learning, (b) considerable impact can be found across a wide range of teachers and conditions, and (c) these gains can be detected even in the absence of other desirable conditions. In particular, detection of student gains does not, in our case, depend on having a long-term context of learning, long-term teacher professional development, or a shift to learner-centered constructivist pedagogy. The full experiment will replicate and extend our experimental design with a wider range of teachers and schools, model the factors that contribute to classroom success with such technology, and explore what happens as research support fades away. 相似文献

SMAR2T: Science and Mathematics Academy for the Recruitment and Retention of Teachers is an NSF-funded project for the alternative
certification of science and mathematics teachers. Since 2003, we have recruited 4 cohorts of students for 2 different routes
to postbaccalaureate teacher certification for teaching grades 5–12. Because we did not meet our target numbers for the recruitment
of the 1st cohort, we examined our recruitment strategies and their effects. In this paper, we discuss strategies used to
recruit for the 1st SMAR2T cohort and the outcomes of those strategies. We present ongoing recruitment efforts and data on inquiries and applicants
for the 2nd cohort. Finally, we highlight the intentional and unintentional gatekeepers of our program and present implications
for others engaged in designing and implementing alternative pathways certification. 相似文献

Coach learning to help teachers learn to enact conceptually rich,student-focused mathematics lessons
Stein Mary Kay Russell Jennifer Lin Bill Victoria Correnti Richard Speranzo Laurie 《Journal of Mathematics Teacher Education》2022,25(3):321-346
The past decade has witnessed a strong, standards-based call for improving what mathematics is taught and how it is taught. In the USA, districts have hired instructional coaches to help teachers shift their teaching from algorithm-based instruction to instruction that is more student-centered and conceptually focused. The purpose of this study was to contribute to the field’s understanding of (a) the specific coaching practices that help teachers enact more conceptual-based forms of instruction; and (b) how coaches learn to enact those practices. Using a design-based implementation research approach, we trained coaches using a particular model for one-on-one coaching (Content-Focused Coaching); the coaches then worked with teachers to plan lessons aligned with the coaching model. Data consisted of videotapes of pre-lesson conferences that were transcribed and coded according to the model. Analyses of 32 coaches’ practice over a 2-year period suggest that each of the three components of our coaching model (attention to student thinking, pedagogy, and mathematics) demonstrated statistically significant improvement over time. An illustrative analysis of five coaching sessions of one coach revealed a progression over five sessions from planning discussions that stayed at the level of general strategies to more specific conversations about teaching a particular task and then to deeper discussions that integrate attention to mathematical concepts, student thinking, and pedagogical moves. We view this delineation of coach learning as an important first step in laying the groundwork for the design of future coach training.

Designing and building an on-line community: The struggle to support sociability in the inquiry learning forum 总被引：1，自引：0，他引：1

In this paper we describe the sociotechnical structures of the Inquiry Learning Forum (ILF), a Web-based professional development
tool designed to support a community of inservice and preservice mathematics and science teachers creating, sharing, and improving
inquiry-based pedagogical practices. Founded in our previous research and consistent with our pedagogical commitment, the
technical structures of the ILF have been designed around a “visiting-the-classroom” metaphor. This decision was based on
our belief that teachers need to be full participants in, and owners of, their virtual space for meaningful interaction to
occur. The hallmark of this environment is that teachers with a broad range of experience and expertise can come together
in an on-line environment to observe, discuss, and reflect on pedagogical theory and practice anchored to actual teaching
vignettes. The goal of this paper is to share how we instantiated our pedagogical commitments and to describe the challenges
we faced during the design, development, implementation, and analysis of the ILF. Toward this end, we walk the reader through
our design and implementation process, highlighting our change in focus from usability to sociability issues, and movement
from conceiving the ILF as an electronic structure to a sociotechnical interaction network.

The Exploring Florida Science project goals were: (1) increasing content knowledge of secondary science teachers, specifically in topics that are important to the future of the state, and (2) providing secondary science students with digital media for use in project-based learning. A team of instructional designers, educators, scientists, web designers and teacher educators designed an online professional development environment. Needs analysis included identification of the high incidence topics on the state science achievement test and topics of socio-scientific importance in the state. Development followed tenets of design-based research, and was guided by E-Learning for Educators standards and evaluated for content, pedagogy and usability using rubrics based on established guidelines. This paper details design, development, and evaluation frameworks, and summarizes pilot testing outcomes. 相似文献

In 2003 the University of Missouri (with the aid of US National Science Foundation funding) initiated an alternative certification
program (ACP) to address the well-documented need in the US for increasing the quantity and quality of mathematics and science
teachers for the middle and secondary levels. Nationwide current certification programs do not provide the quality and quantity
of mathematics and science teachers needed in schools. As a result most American states have begun to experiment with ACPs
as a way to address the shortage of math and science teachers. To evaluate the success of this program, we collected data
from ACP participants regarding perceived preparation, self efficacy, and outcome expectancy at three time points in the program.
State standards for beginning teachers were used to construct a perceived preparation instrument. Analysis of data suggests
that over time, ACP participants exhibited an increasingly positive view toward their preparation for classroom teaching,
as well as increased self efficacy. However, there was little change in the students’ outcome expectancy over time. In this
article we share details of the unique ACP program and we describe steps taken to collect and evaluate a project data set.
Our work provides useful guidance to researchers and practitioners in the field of science and mathematics teacher education. 相似文献

We investigated secondary science and mathematics teachers engaged in a two-and-a-half-year professional development effort focused on equity. We examined how teachers conducting research on their own instructional practices—a central learning strategy of the professional development project—informed and/or constrained their views related to three strands of equity: teachers and teaching, students and learning, and students’ families and communities. Data collected included recordings of professional development seminars and school-site meetings, three sets of individual interviews with teacher researchers, and drafts and final products of the classroom research teachers conducted. From our qualitative analyses of data, we found that most teachers addressed at least two of the three equity strands in researching their own practice. We also found that most transformed their understandings of teachers and students as a result of their teacher research process. However, teachers’ views of families and communities changed in less substantive ways. We close with recommendations for other researchers and professional developers intent on supporting science and mathematics teachers in using teacher research to work toward equity. 相似文献

A Conceptual Framework for Learning to Teach Secondary Mathematics: A Situative Perspective 总被引：1，自引：1，他引：1
Dominic Peressini Hilda Borko Lew Romagnano Eric Knuth Christine Willis 《Educational Studies in Mathematics》2004,56(1):67-96
This paper offers for discussion and critique a conceptual framework that applies a situative perspective on learning to the
study of learning to teach mathematics. From this perspective, such learning occurs in many different situations -- mathematics
and teacher preparation courses, pre-service field experiences, and schools of employment. By participating over time in these
varied contexts, mathematics teachers refine their conceptions about their craft -- the big ideas of mathematics, mathematics-specific
pedagogy, and sense of self as a mathematics teacher. This framework guides a research project that traces the learning trajectories
of teachers from two reform-based teacher preparation programs into their early teaching careers. We provide two examples
from this research to illustrate how this framework has helped us understand the process of learning to teach.

Our work is in keeping with the general framework of didactical research in France, where we both studied, and now teach. This paper describes a model training session designed for in-service mathematics teachers, whose purpose is to guide them in their understanding of the relationship between students’ tasks and activities in secondary school (from 11 to 18 years). We first explain the didactical tools that we consider necessary in order to address tasks analysis, and then, as an example of a training session, we provide a list of tasks on similar triangles illustrating the two kinds of analysis in which we engage participants. As a conclusion to this paper, we comment on our choices, and their potential influence on teachers’ practices. 相似文献

Senior pre-university education (SPE) students experience difficulties applying mathematics to physics. This paper reports the outcome of an online explorative quantitative study of teachers' belief systems about improving transfer of algebraic skills from mathematics into physics, conducted among 503 mathematics and physics teachers working in SPE. We used a questionnaire with 16 beliefs about improving transfer, and asked teachers to select a top 5 and distribute 50 points among them. We used agglomerative hierarchical clustering to cluster qualified SPE teachers with more than 10 years of teaching experience. We found 3 large clusters, each containing naïve and desirable beliefs about transfer. These clusters turned out to be rather coherent sets of beliefs. Hence, these clusters can be interpreted as belief systems, to a certain extent justifying Ernest's [(1991). The philosophy of mathematics education. London: Falmer.] idea to cluster teachers based on their belief systems. We found relations between our groups and those of Ernest. Since naïve beliefs turn out to be weak in each cluster, science teacher educators can help science teachers to change their harmful naïve beliefs, into desirable transfer enhancing beliefs. Furthermore, we discuss some implications of our results for science teacher educators, curricula, teachers and textbooks. 相似文献

Existing computational thinking (CT) research focuses on programming in K-12 education; however, there are challenges in introducing it into the formal disciplines. Therefore, we propose the introduction of non-programming plugged learning in mathematics to develop students’ CT. The research and teaching teams collaborated to develop an instructional design for primary school students. The participants were 112 third- and fourth-grade students (aged 9–10) who took part in three rounds of experiments. In this paper, we present an iterative problem-solving process in design-based implementation research, focusing on the implementation issues that lead to the design principles in the mathematics classroom. The computational tasks, environment, tools, and practices were iteratively improved over three rounds to incorporate CT effectively into mathematics. Results from the CT questionnaire demonstrated that the new program could significantly improve students’ CT abilities and compound thinking. The results of the post-test revealed that CT, including the sub-dimensions of decomposition, algorithmic thinking, and problem-solving improved threefold compared to the pre-test between the three rounds, indicating that strengthened CT design enhanced CT perceptions. Similarly, the students’ and teacher’ interviews confirmed their positive experiences with CT. Based on empirical research, we summarize design characteristics from computational tasks, computational environment and tools, and computational practices and propose design principles. We demonstrate the potential of non-programming plugged learning for developing primary school students’ CT in mathematics.

One major obstacle for integrating the history of mathematics in teaching (hereafter referred to as IHT) is how to help teachers, particularly those who lack experience in IHT, use historical materials in their teaching. Based on many IHT practices in Shanghai, this paper proposes an IHT framework including two parts: one is a triangular pyramid IHT model, and the other is a design-based IHT procedure. The pyramid model is composed of three different communities: teachers, researchers, and historians of mathematics. The design-based procedure, also called operating model, includes cyclic stages, which are investigation, design, implementation, assessment, and publication. The primary purpose of this framework is to build a bridge between theory and practice by combining the two models to address particular teaching concerns and improve teaching. In addition, this paper details the process of the dynamic pyramid model and the design-based IHT procedure, and illustrates an example of the application of this framework. Finally, this paper discusses the differences and similarities between this model and others and also discusses the challenge of applying this model in practice. 相似文献

This exploratory study examines the impact of a collaborative inquiry- and design-based afterschool program on urban high school students’ IT/STEM learning—using information technology (IT) within the context of science, technology, engineering, and mathematics (STEM). The study used a mixed methods design, involving 77 participants within two cohort groups, each participating in an eighteen-month intervention period. Data were collected from the pre- and post-surveys, analysis of the participants’ IT/STEM projects, external evaluation reports, and follow-up interviews. Findings indicate that the program had a significant impact on students’ technology and IT/STEM skills, frequency of technology use, and understanding of IT use in STEM-oriented fields. Some degree of impact on attitude changes toward IT/STEM and career aspirations in these fields was also in evidence. The study demonstrates that IT/STEM experiences supported through technology-enhanced, inquiry- and design-based collaborative learning strategies have significant impact on urban high school students’ IT/STEM learning. Effect of afterschool programs on attitude changes and IT/STEM-related career aspirations of urban high school students are recommended areas of further investigation. 相似文献

This study documented the process of evolution of the continuous design and revision of the tools of a novice mathematics teacher educator–researcher (MTE-R) as he planned and implemented design-based professional development workshops for in-service mathematics teachers in Taiwan. In order to effectively facilitate teachers designing and implementing their own conjecturing activities during the workshops, the MTE-R fostered their professional learning and growth through reflection upon students’ performance. From the perspective of activity theory, this study examined the evolution of the MTE-R’s mentoring activities and tools whose design gradually changed from being based on the literature content toward being learner-centered activities with teachers as learners. Such evolution not only enhanced teachers’ learning outcomes, but also facilitated the MTE-R’s own professional growth in different areas, including mathematics, mathematics learning, mathematics teaching, teacher education, and, in particular, the extrapolation of generic examples for understanding mathematical concepts. 相似文献
