School visits to natural history museums: Teaching or enriching?

This article describes a 3‐year study of school visits to four natural history museums and addresses the research agenda with regard to out‐of‐school learning. More specifically, the findings focus on the process of learning in museums. Comprehensive data collection allowed for an analysis of patterns of guided visits, the way the scientific content was conveyed to students, and the extent and types of social interactions thus enabled. Observations of 42 guided visits (grades 3–11) indicates that the main visitation pattern consisted of guide‐centered and task‐oriented activity. Analysis of questions asked by museum guides reveals that most of these questions required mainly lower‐order thinking skills. A common questioning pattern was to ask rhetorical questions as a means of carrying on the lecture. Detailed analysis of the scientific vocabulary used by the guides indicates that they used much scientific jargon, with limited explanation. There was only limited social mediation provided by teachers and museum guides. A minority of teachers were involved in the activities or in helping the guide to clarify or in helping the students to understand the explanations. The overall data indicate limited opportunities for meaningful learning, suggesting that the museums should shift from the traditional knowledge‐transmission model of teaching to a more socioculturally contextualized model. © 2007 Wiley Periodicals, Inc.

Urban 5th graders conceptions during a place‐based inquiry unit on watersheds

This study aimed to determine how 33 urban 5th grade students' science conceptions changed during a place‐based inquiry unit on watersheds. Research on watershed and place‐based education was used as a framework to guide the teaching of the unit as well as the research study. A teacher‐researcher designed the curriculum, taught the unit and conducted the research using qualitative data sources such as concept maps, science notebooks and interviews. Most students came to understand that their watershed was part of an urban environment where water drains from the surrounding land into a body of water. Thus, they began to understand how urban land use affects water quality. This study provides evidence for the use of place‐based learning in developing students' knowledge of the National Science Education Standards (NRC, 1996) and watersheds. Implications of this study include the use of place‐based learning in urban settings and the experiences needed for students to conceptualize watersheds. © 2009 Wiley Periodicals, Inc.

An examination of teacher–student interactions in inclusive classrooms: teacher interviews and classroom observations

Teacher–student interactions in 17 inclusive classrooms were examined using a mixed‐methods approach that involved quantitative analysis of interactions recorded during classroom observations and follow‐up interviews with seven general educators. Observational findings suggest that classrooms were organised along traditional lines with the vast majority of interactions provided by general educators to the whole class, followed by brief intervals of 1 : 1 interactions directed towards individual students, most frequently children with disabilities. Interview findings suggest that teachers were aware of the greater individual attention devoted to students with disabilities and described a number of ways that they adapt their instruction that are consistent with the research on effective teaching. In addition, participants struggled with the dilemma of balancing their attention between students whom they perceived as needing it most and ensuring that the class as a whole made adequate progress. The analysis of both observational and interview data indicates that paraprofessionals were responsible for a large portion of instruction and curricular decision making for children with severe disabilities in these classrooms.     

Students in service of the state: Uncoupling student trips abroad and global competence

Student exchange programs and trips abroad are consistently portrayed in scholarship as a strategy for promoting students’ global competence. Through a thematic document analysis of a mandatory course developed by the Israeli MOE for students embarking on trips abroad and additional sources, I explore the discourse used to portray these trips in the Israeli context, showing an alternative model that places the state rather than students at the center of these programs. Although from an education perspective this discourse is distinct, political science scholarship suggests the goals it embodies could be embedded across many national contexts, albeit more discretely.     

Measuring instructional practice in science using classroom artifacts: lessons learned from two validation studies

With growing interest in the role of teachers as the key mediators between educational policies and outcomes, the importance of developing good measures of classroom processes has become increasingly apparent. Yet, collecting reliable and valid information about a construct as complex as instruction poses important conceptual and technical challenges. This article summarizes the results of two studies that investigated the properties of measures of instruction based on a teacher‐generated instrument (the Scoop Notebook) that combines features of portfolios and self‐report. Classroom artifacts and teacher reflections were collected from samples of middle school science classrooms and rated along 10 dimensions of science instruction derived from the National Science Education Standards; ratings based on direct classroom observations were used as comparison. The results suggest that instruments that combine artifacts and self‐reports hold promise for measuring science instruction with reliability similar to, and sizeable correlations with, measures based on classroom observation. We discuss the implications and lessons learned from this work for the conceptualization, design, and use of artifact‐based instruments for measuring instructional practice in different contexts and for different purposes. Artifact‐based instruments may illuminate features of instruction not apparent even through direct classroom observation; moreover, the process of structured collection and reflection on artifacts may have value for professional development. However, their potential value and applicability on a larger scale depends on careful consideration of the match between the instrument and the model of instruction, the intended uses of the measures, and the aspects of classroom practice most amenable to reliable scoring through artifacts. We outline a research agenda for addressing unresolved questions and advancing theoretical and practical knowledge around the measurement of instructional practice. © 2011 Wiley Periodicals, Inc.

Pedagogical content knowledge as reflected in teacher–student interactions: Analysis of two video cases

Despite the theorized centrality of pedagogical content knowledge (PCK) for teaching, we have little evidence of the relationship between PCK and students' learning and know relatively little about how to help teachers to develop PCK. This study is a preliminary attempt to address these gaps in our knowledge of PCK through exploration of two German physics teachers' classroom instruction in consecutive lessons on optics. We show how video analysis can be used to gather evidence for one aspect of teachers' PCK: their use of content knowledge in interactions with students. We identify three potentially important characteristics of this aspect of PCK: flexibility, richness, and learner‐centeredness. By contrasting teachers with high and low gains in student knowledge and interest, we explore potential mechanisms by which this aspect of PCK might affect student outcomes. Because German teacher preparation programs emphasize content more than pedagogical knowledge, these cases contribute to our understanding of the support that teachers with strong content knowledge may need in translating this knowledge into a form useful for teaching.Fachdidaktisches Wissen ist aus theoretischer Sicht besonders zentral für das Unterrichten. Aus empirischer Sicht gibt es bislang allerdings noch wenig Evidenz für den Einsatz fachdidaktischen Wissens während des Unterrichtens und seine Bedeutung für das Lernen von Schülerinnen und Schülern. Außerdem wissen wir wenig darüber, wie Lehrpersonen über die Zeit fachdidaktisches Wissen entwickeln. Diese Studie ist ein Versuch, diese Wissenslücken zum fachdidaktischen Wissen von Lehrpersonen zu bearbeiten. Dabei wird exemplarisch der Unterricht von zwei deutschen Physiklehrern in aufeinanderfolgenden Stunden zum Thema Optik untersucht. Die Studie zeigt wie Videoanalysen genutzt werden können, um Belege für einen Aspekt des fachdidaktischen Wissens der Lehrpersonen zu sammeln: Ihre Nutzung von inhaltlichem Wissen in der Interaktion mit den Schülerinnen und Schülern. In dieser Studie werden drei potentiell wichtige Charakteristika dieses Aspekts des fachdidaktischen Wissens identifiziert: Flexibilität, Reichhaltigkeit und Schülerorientierung. Durch die Gegenüberstellung von Lehrpersonen mit hohem und niedrigem Wissens‐ und Interessenzuwachs wurden potentielle Mechanismen untersucht, durch die dieser Aspekt des fachdidaktischen Wissens die Lernergebnisse von Schülerinnen und Schülern beeinflussen kann. Die Lehrerausbildung in Deutschland betont das inhaltliche Wissen stärker als das fachdidaktische Wissen. Die ausgewählten Fälle beschreiben, welche Unterstützung Lehrpersonen mit einem hohen fachlichen Wissen benötigen, um dieses Wissen so zu verändern, dass es für das Unterrichten genutzt werden kann. © 2012 Wiley Periodicals, Inc.

Improvisation: An analytic tool for examining teacher–child interactions in the early childhood classroom

This article explores the use of improvisation (improv) as a lens for viewing and describing teacher–child interactions. The author describes the relationship between the principles of improv and the characteristics of responsive teaching, and how improv can be used as a lens for seeing relational activity. The author hypothesizes that improv would provide a valuable tool for understanding and describing what is happening between teachers and children. An in-depth case study was conducted of an experienced early childhood teacher in a play-based classroom. Analysis was done using both the codes derived from the teacher–child interaction literature and improv theory. Improv analysis offered a nuanced picture of what early childhood teachers are doing in practice. The findings revealed that using improv provides a lens for seeing teacher–child interactions as an ensemble activity and what the teacher is doing in terms of its usefulness to the activity. While this study focused on a single teacher in one classroom, the findings demonstrate the potential of an improv lens for developing and deepening our understanding of early childhood teaching.     

An investigation of the goals for an environmental science course: teacher and student perspectives

This investigation uses an ethnographic case study approach to explore the benefits and challenges of including a variety of goals within a high school Environmental Science curriculum. The study focuses on environmental education (EE) goals established by the Belgrade Charter (1975), including developing students’ environmental awareness and behavior, but also explores alternative goals including empowerment, presenting a balanced perspective, improving critical thinking skills, and developing an emotional connection with environmental issues. This research, which was conducted at a public high school in the northeast United States, aims to understand the teacher’s reasoning for including the above goals within the curriculum and the students’ reactions to the enactment of these goals. Interview data from 10 student participants and the teacher reveal areas of alignment between teacher and student perspectives regarding goals such as presenting a balanced approach, as well as misalignment in areas such as the teaching of environmentally friendly behaviors.     

Developing interactive mathematical talk: investigating student perceptions and accounts of mathematical reasoning in a changing classroom context

In recent years there has been an increased focus on the need for teachers to develop learning communities where all students have opportunities to engage in interactive discourse. However, there are few studies that focus on student perceptions and accounts of mathematical reasoning in classrooms with interactive mathematical talk as a focus of reform. A framework of teacher actions to develop classroom and mathematical practices was developed from classroom observations. Photo-elicitation interviews were used to investigate student perception and accounts of mathematical explanations and reasoning. The professional development programme, shifts in the teacher actions, and subsequent shifts in student perception and their recall of their own and peers’ mathematical reasoning over a school year are highlighted. Developing interactive dialogue in the classroom took considerable time and attention. Facilitating change to the way students both participated and understood their obligations required constant, ongoing attention to both the classroom and mathematical practices.

The consequences of “school improvement”: Examining the association between two standardized assessments measuring school improvement and student science achievement

For more than half a century concerns about the ability of American students to compete in a global workplace focused policymakers' attention on improving school performance generally, and student achievement in science, technology, engineering, and mathematics (STEM) specifically. In its most recent form—No Child Left Behind—there is evidence this focus led to a repurposing of instructional time to dedicate more attention to tested subjects. While this meant a narrowing of the curriculum to focus on English and mathematics at the elementary level, the effects on high school curricula have been less clear and generally absent from the research literature. In this study, we sought to explore the relationship between school improvement efforts and student achievement in science and thus explore the intersection of school reform and STEM policies. We used school‐level data on state standardized test scores in English and math to identify schools as either improving or declining over three consecutive years. We then compared the science achievement of students from these schools as measured by the ACT Science exams. Our findings from three consecutive cohorts, including thousands of high school students who attended 12th grade in 2008, 2009, and 2010 indicate that students attending improving schools identified by state administered standardized tests generally performed no better on a widely administered college entrance exam with tests in science, math and English. In 2010, students from schools identified as improving in English scored nearly one‐half of a point lower than their peers from declining schools on both the ACT Science and Math exams. We discuss various interpretations and implications of these results and suggest areas for future research. © 2012 Wiley Periodicals, Inc. J Res Sci Teach 49: 804–830, 2012     

‘Being dyslexic doesn't make me less of a teacher’. School placement experiences of student teachers with dyslexia: strengths,challenges and a model for support

This research investigated the school practice placement experiences of six student teachers with dyslexia representing each year of a 3‐year initial teacher training course at a UK university. Placement performance and outcome has enormous implications for student teachers in demonstrating their professional competence and ability to meet the Training and Development Agency for Schools Professional Standards for Teachers and obtain qualified teacher status. The research focused thematically on student strengths, challenges and management strategies using a case research approach. Findings indicate student teachers with dyslexia bring unacknowledged strengths to placements but face a number of challenges despite proactive adoption of management strategies. A model of placement support to enhance student effectiveness has been developed. Conclusions indicate the importance of listening to the student's voice to understand individual placement requirements and co‐ordinate and implement specific reasonable adjustments as required by UK legislation 1 .     

Teachers as mothers in the elementary classroom: negotiating the needs of self and other

In this paper, I interrogate the implicit and largely unexamined relationship between mothering and elementary teaching as they are informed by dominant notions of caring in the United States. In an environment where students were seen as not receiving adequate care at home, the teachers in this study felt a need to act as mothers in their professional lives. The consequences of such “deficit thinking” for students are well explored in the literature on teaching and learning. What has been less well explored are the consequences of this teacher‐as‐mother notion for teachers themselves. Drawing from the narratives of six women elementary school teachers, I suggest that assuming the role of mother to one's students not only devalues students' identity and experience, but limits teachers' ability to adequately care for themselves.     

Beliefs about learning and enacted instructional practices: An investigation in postsecondary chemistry education

While research on and development of evidence‐based instructional practices (EBIPs) in STEM education has flourished, implementation of these practices classrooms has not been as prolific. Using the teacher‐centered systemic reform model as a framework, we explore the connection between chemistry instructors’ beliefs about teaching and learning and self‐efficacy beliefs, and their enacted classroom practices. Postsecondary chemistry faculty present a unique population for the study because of their role in teaching prerequisite courses, such as general and organic chemistry, which are key to many science major fields. A measure of teacher beliefs and self‐efficacy was administered to a national survey of postsecondary chemistry faculty members. Instructional practices used in a chemistry course were also collected via self‐report. While instructional practices were not directly observed, a cluster analysis of our data mirrors patterns of instructional practices found in observation‐based studies of chemistry faculty. Significant differences are found on teacher thinking and self‐efficacy measures based on enacted instructional practices. Results support the hypothesized connection between beliefs and instructional practice on a larger scale than in previous studies of this relationship, bolstering the evidence for the importance of this relationship over previously criticized results. These results present a call for reform efforts on fostering change from its core, that is, the beliefs of those who ultimately adopt EBIPs. Dissemination and design should incorporate training and materials that highlight the process by which faculty members interpret reformed practices within their belief system, and explore belief change in the complex context of education reform.
