The purpose of this study was to understand what preservice teachers and knowledgeable others professionally notice as they engaged in repeated cycles of a modified version of lesson study, as a component of a field experience in a teacher education program. The study also centered on comparing the professional noticing practices of preservice teachers with other lesson study participants, including classroom teachers and university facilitators. Data analyzed included videos of weekly lesson study analysis meetings for seven weeks for each of four teams. Each team included six preservice teachers, a classroom teacher, and a university facilitator. Findings indicate that preservice teachers primarily noticed elements about the classroom environment and teacher pedagogy, but included instances of noticing centered on students' mathematical thinking. In contrast, classroom teachers and university facilitators, as knowledgeable others, typically noticed general events and were less focused on students' mathematical thinking. Analysis of noticing trends over the seven weeks indicated that noticing levels remained steady initially, dropped in the fourth and fifth week, and resumed original status in the final weeks. Results that the preservice teachers' noticing comments were at higher levels than the knowledgeable others are contrary to other research studies and indicate that incorporating lesson study with appropriate scaffolds into a field experience for preservice teachers may be a viable option for encouraging noticing of students' mathematical thinking.  相似文献

This study was designed to use critical reflective journaling practices to explore the experiences of preservice teachers working in a juvenile justice education program called the Reach Academy. Using a qualitative case study design, the researchers explored how 48 preservice teachers utilized critical reflective journaling to examine their own identities in relation to working in this unique school setting. Three major themes emerged from the reflective journal and interview data: (a) participants preconceived notions were challenged based on their positive interactions with Reach students, (b) preservice participants engaged in critical observation of the Reach Academy teachers and their interactions with students, and (c) participants' focus shifted from themselves to their students' needs. Findings suggest that preservice teachers reflective journaling process facilitated their ability to examine and reconsider their preconceived notions about working with students at the Reach Academy and in other diverse schooling settings.  相似文献

Part of the work of teaching elementary science involves evaluating elementary students' work. Depending on the nature of the student work, this task can be straightforward. However, evaluating elementary students' representations of their science learning in the form of scientific models can pose significant challenges for elementary teachers. To address some of these challenges, we incorporated a modeling-based elementary science unit in our elementary science teaching methods course to support preservice teachers in gaining knowledge about and experience in evaluating students' scientific models. In this study, we investigate the approaches and criteria preservice elementary teachers use to evaluate elementary student-generated scientific models. Our findings suggest that with instruction, preservice elementary teachers can adopt criterion-based approaches to evaluating students' scientific models. Additionally, preservice teachers make gains in their self-efficacy for evaluating elementary students' scientific models. Taken together, these findings indicate that preservice teachers can begin to develop aspects of pedagogical content knowledge for scientific modeling.  相似文献

Teacher knowledge is a critical focus of educational research in light of the potential impact of teacher knowledge on student learning. The dearth of research exploring entry-level preservice teachers' geometric knowledge poses an onerous challenge for mathematics educators in initial teacher education (ITE) when designing experiences that develop preservice teachers' geometric knowledge to support the task of teaching. This study examines the geometric thinking levels of entry-level Irish preservice primary teachers (N = 381). Participants' geometric thinking levels were determined through a multiple-choice geometry test (van Hiele Geometry Test) prior to commencing a Geometry course within their ITE program. The findings reveal limited geometric thinking among half of the cohort and question the extent to which pre-tertiary experiences develop appropriate foundations to facilitate a smooth transition into ITE mathematics programs. The study also examines the nature of misconceptions among those with limited geometric thinking and presents suggestions to enhance the geometric understandings of preservice teachers.  相似文献

Current research indicates that student engagement in scientific argumentation can foster a better understanding of the concepts and the processes of science. Yet opportunities for students to participate in authentic argumentation inside the science classroom are rare. There also is little known about science teachers' understandings of argumentation, their ability to participate in this complex practice, or their views about using argumentation as part of the teaching and learning of science. In this study, the researchers used a cognitive appraisal interview to examine how 30 secondary science teachers evaluate alternative explanations, generate an argument to support a specific explanation, and investigate their views about engaging students in argumentation. The analysis of the teachers' comments and actions during the interview indicates that these teachers relied primarily on their prior content knowledge to evaluate the validity of an explanation rather than using available data. Although some of the teachers included data and reasoning in their arguments, most of the teachers crafted an argument that simply expanded on a chosen explanation but provided no real support for it. The teachers also mentioned multiple barriers to the integration of argumentation into the teaching and learning of science, primarily related to their perceptions of students' ability levels, even though all of these teachers viewed argumentation as a way to help students understand science. © 2012 Wiley Periodicals, Inc.

For students to meaningfully engage in science practices, substantive changes need to occur to deeply entrenched instructional approaches, particularly those related to classroom discourse. Because teachers are critical in establishing how students are permitted to interact in the classroom, it is imperative to examine their role in fostering learning environments in which students carry out science practices. This study explores how teachers describe, or frame, expectations for classroom discussions pertaining to the science practice of argumentation. Specifically, we use the theoretical lens of a participation framework to examine how teachers emphasize particular actions and goals for their students' argumentation. Multiple-case study methodology was used to explore the relationship between two middle school teachers' framing for argumentation, and their students' engagement in an argumentation discussion. Findings revealed that, through talk moves and physical actions, both teachers emphasized the importance of students driving the argumentation and interacting with peers, resulting in students engaging in various types of dialogic interactions. However, variation in the two teachers' language highlighted different purposes for students to do so. One teacher explained that through these interactions, students could learn from peers, which could result in each individual student revising their original argument. The other teacher articulated that by working with peers and sharing ideas, classroom members would develop a communal understanding. These distinct goals aligned with different patterns in students' argumentation discussion, particularly in relation to students building on each other's ideas, which occurred more frequently in the classroom focused on communal understanding. The findings suggest the need to continue supporting teachers in developing and using rich instructional strategies to help students with dialogic interactions related to argumentation. This work also sheds light on the importance of how teachers frame the goals for student engagement in this science practice.  相似文献

Fostering students' spatial thinking skills holds great promise for improving Science, Technology, Engineering, and Mathematics (STEM) education. Recent efforts have focused on the development of classroom interventions to build students' spatial skills, yet these interventions will be implemented by teachers, and their beliefs and perceptions about spatial thinking influence the effectiveness of such interventions. However, our understanding of elementary school teachers' beliefs and perceptions around spatial thinking and STEM is in its infancy. Thus, we created novel measures to survey elementary teachers' anxiety in solving spatial problems, beliefs in the importance of spatial thinking skills for students' academic success, and self-efficacy in cultivating students' spatial skills during science instruction. All measures exhibited high internal consistency and showed that elementary teachers experience low anxiety when solving spatial problems and feel strongly that their skills can improve with practice. Teachers were able to identify educational problems that rely on spatial problem-solving and believed that spatial skills are more important for older compared to younger students. Despite reporting high efficacy in their general teaching and science teaching, teachers reported significantly lower efficacy in their capacities to cultivate students' spatial skills during science instruction. Results were fairly consistent across teacher characteristics (e.g., years of experience and teaching role as generalist or specialist) with the exception that only years of teaching science was related to teachers' efficacy in cultivating students' spatial thinking skills during science instruction. Results are discussed within the broader context of teacher beliefs, self-efficacy, and implications for professional development research.  相似文献

Recognizing that students of color often do not achieve as well as their White counterparts, the authors of this article acknowledged the need for preservice teachers to study racial and cultural issues as they relate to teaching in diverse classrooms. For four months prior to the beginning of the course that the authors would co-teach, they systematically read multiple articles and book chapters about racial and cultural issues in schools and met weekly to discuss, from their own perspectives and experiences, their reactions to the readings. Simultaneously, they considered emerging possibilities for a course curriculum where preservice teachers would explore issues important to what they called creating culturally celebratory pedagogy and classrooms. The authors, a Black faculty member and a White faculty member in a teacher education program, share key questions that emerged from their readings and discussions, describe four major components they integrated into the course curriculum, and present assignments that may reduce preservice teachers' deficit knowledge and thinking about racial and cultural issues in classrooms and schools. The authors also consider students' initial reactions to the course content and what the students' reactions might mean for the structure and restructure of the course.  相似文献

The purpose of this research was to understand how preservice elementary teacher experiences within the context of reflective science teacher education influence the development of professional knowledge. We conducted a case analysis to investigate one preservice teacher's beliefs about science teaching and learning, identify the tensions with which she grappled in learning to teach elementary science, understand the frames from which she identified problems of practice, and discern how her experiences played a role in framing and reframing problems of practice. The teacher, Barbara, encountered tensions in thinking about science teaching and learning as a result of inconsistencies between her vision of science teaching and her practice. Confronting these tensions between ideals and realities prompted Barbara to rethink the connections between her classroom actions and students' learning and create new perspectives for viewing her practice. Through reframing, she was able to consider and begin implementing alternative practices more resonant with her beliefs. Barbara's case illustrates the value of understanding prospective teachers' beliefs, their experiences, and the relationship between beliefs and classroom actions. Furthermore, the findings underscore the significance of offering reflective experience as professionals early in the careers of prospective teachers. © 1999 John Wiley & Sons, Inc.

This paper reports a study of preservice teachers who investigated their own teaching during a field-based component of a mathematics education methods course. The course was designed to engage the preservice teachers in both mathematical and pedagogical inquiry. Analysis of video recordings of course discussions, audiotaped interviews with preservice teachers, audiotaped discussions of instructor's planning meetings, and copies of the instructor's and preservice teachers' journals identified two critical incidents that depict students' resistance to the course directions. Analysis of these critical incidents suggests that prospective teachers' interactions with their students can become the mirror through which we can investigate their interactions with us, as teacher educators, and with our course activities. In this way we might reframe the problem of resistance to one of listening—listening to the students, to each other, and to ourselves.  相似文献

This study investigated whether listening to spontaneous conversations of elementary students and their teachers/chaperones, while they were visiting a zoo, affected preservice elementary teachers' conceptions about planning a field trip to the zoo. One hundred five preservice elementary teachers designed field trips prior to and after listening to students' conversations during a field trip to the zoo. In order to analyze the preservice teachers' field trip designs, we conducted a review of the literature on field trips to develop the field trip inventory (FTI). The FTI focussed on three major components of field trips: cognitive, procedural, and social. Cognitive components were subdivided into pre-visit, during-visit, and post-visit activities and problem-solving. Procedural components included information about the informal science education facility (the zoo) and the zoo staff and included advanced organizers. Social components on student groups, fun, control during the zoo visit, and control of student learning. The results of the investigation showed that (a) the dominant topic in conversations among elementary school groups at the zoo was management, (b) procedural components were mentioned least often, (c) preservice teachers described during-visit activities more often than any other characteristic central to field trip design, (d) seven of the nine characteristics listed in the FTI were noted more frequently in the preservice teachers' field trip designs after they listened to students' conversations at the zoo, and (e) preservice teachers thought that students were not learning and that planning was important.  相似文献

In recent years, the use of data to inform instructional decision making has become a particularly prominent facet of K–12 educators' professional practice. However, research estimates limited opportunities for preservice teachers to learn how to use data, including standardized test data, for such purposes. In response, this article describes the results of a pretest–posttest study of a 6-hour standardized assessment data use intervention for preservice teachers. The facilitated, collaborative, and highly structured assessment course-embedded intervention engaged preservice teachers in asking and answering four different kinds of questions (e.g., achievement strengths and weaknesses, instructional implications) at five different student levels (e.g., individual, subgroup, school) with external assessment data presented in tables, charts, and score reports. Findings—which include highly favorable preservice teacher perceptions of the intervention's impact on their data-driven decision making skills, and changes in their self-efficacy and data interpretation skills—indicate that the intervention holds promise as a preservice teacher learning mechanism.  相似文献

With the goal of producing scientifically literate citizens who are able to make informed decisions and reason critically when science intersects with their everyday lives, the National Research Council (NRC) has produced two recent documents that call for a new approach to K-12 science education that is based on scientific practices, crosscutting concepts, and disciplinary core ideas. These documents will potentially influence future state standards and K-12 curricula. Teachers will need support in order to teach science using a practices based approach, particularly if they do not have strong science backgrounds, which is often the case with elementary teachers. This study investigates one cohort (n = 19) of preservice elementary teachers’ ideas about scientific practices, as developed in a one-semester elementary science teaching methods course. The course focused on eight particular scientific practices, as defined by the National Research Council’s A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012). Participants’ written reflections, lesson plans and annotated teaching videos were analyzed in fine detail to better understand their ideas about what it means to engage in each of the practices. The findings suggest that preservice elementary teachers hold promising ideas about scientific practices (such as an emphasis on argumentation and communication between scientists, critical thinking, and answering and asking questions as the goal of science) as well as problematic ideas (including confusion over the purpose of modeling and the process of analysis, and conflating argumentation and explanation building). These results highlight the strengths and limitations of using the Framework (NRC 2012) as an instructional text and the difficulties of differentiating between preservice teachers’ content knowledge about doing the practices and their pedagogical knowledge about teaching the practices.  相似文献

Three-term contingency trials (TCTs) involve planned/naturally occurring antecedents, child's demonstration of target behaviors, and planned/naturally occurring consequences. Positive relationships between teachers' frequent use of TCTs and children's learning were noted in literature. This study aimed to investigate impact of an intervention package including training and coaching with performance feedback on experienced and novice special education preservice teachers' use of TCTs and relationship between teachers' implementation and child outcomes through two single-case experiments using multiple baseline across participants design. Three special education preservice teachers and three children with disabilities participated in each study. Results indicated intervention package was effective in increasing preservice teachers' use of TCTs. Preservice teachers generalized their use and sustained it during maintenance sessions conducted after intervention ended. Furthermore, as frequency and accuracy of preservice teachers' implementation increased, percentage of children's correct responses in relation to target skills improved. Implications for future practice and research are discussed.  相似文献

The purpose of this study was to examine the effects of a year-long professional development program in classroom discussion designed to improve students' argumentation skills in language arts classes. Twenty-six fifth-grade teachers and their 471 students at two research sites participated: 14 teachers in the experimental condition, who received the professional development, and 12 teachers in the comparison condition. Results showed that the professional development led to statistically significant improvements in the quality of teachers' facilitation and student argumentation during discussions, and in students' performance on individual argumentative reading and writing tasks following the discussions, at the end of the year. Findings suggest that the professional development for teachers resulted in strengthened student abilities to connect positions with relevant reasons and evidence, and that argumentation skills acquired in the discussions may have transferred to students’ individual argumentation, at least for reading outcomes.  相似文献

The literature provides confounding information with regard to questions about whether students in high school can engage in meaningful argumentation about socio‐scientific issues and whether this process improves their conceptual understanding of science. The purpose of this research was to explore the impact of classroom‐based argumentation on high school students' argumentation skills, informal reasoning, and conceptual understanding of genetics. The research was conducted as a case study in one school with an embedded quasi‐experimental design with two Grade 10 classes (n = 46) forming the argumentation group and two Grade 10 classes (n = 46) forming the comparison group. The teacher of the argumentation group participated in professional learning and explicitly taught argumentation skills to the students in his classes during one, 50‐minute lesson and involved them in whole‐class argumentation about socio‐scientific issues in a further two lessons. Data were generated through a detailed, written pre‐ and post‐instruction student survey. The findings showed that the argumentation group, but not the comparison group, improved significantly in the complexity and quality of their arguments and gave more explanations showing rational informal reasoning. Both groups improved significantly in their genetics understanding, but the improvement of the argumentation group was significantly better than the comparison group. The importance of the findings are that after only a short intervention of three lessons, improvements in the structure and complexity of students' arguments, the degree of rational informal reasoning, and students' conceptual understanding of science can occur. © 2010 Wiley Periodicals, Inc.

When teachers believe that students' abilities are fixed, their students' motivation, well-being, and performance tend to suffer. While many interventions have been developed to reduce these so-called fixed mindsets in students and increase the belief that abilities are malleable (i.e., a growth mindset), there are no cost-effective, scalable interventions targeting teachers' mindsets. To address this need, we developed a brief intervention consisting of a reflection task in which teachers thought and wrote about their mission as educators. Two experiments with preservice teachers (total N = 576) revealed that this brief intervention increased their growth mindsets (meta-analytic d = 0.25). This increase did not dissipate over the course of a week (meta-analytic d = 0.26), suggesting the intervention's effects are not ephemeral. Although more work is needed to establish the robustness and generalizability of this intervention's effects, it may ultimately become a useful tool for teacher education programs.  相似文献
