Discovering Plate Boundaries in Data-integrated Environments: Preservice Teachers' Conceptualization and Implementation of Scientific Practices

Drawn from the norms and rules of their fields, scientists use variety of practices, such as asking questions and arguing based on evidence, to engage in research that will contribute to our understanding of Earth and beyond. In this study, we explore how preservice teachers' learn to teach scientific practices while teaching plate tectonic theory. In particular, our aim is to observe which scientific practices preservice teachers use while teaching an earth science unit, how do they integrate these practices into their lessons, and what challenges do they face during their first time teaching of an earth science content area integrated with scientific practices. The study is designed as a qualitative, exploratory case study of seven preservice teachers while they were learning to teach plate tectonic theory to a group of middle school students. The data were driven from the video records and artifacts of the preservice teachers' learning and teaching processes as well as written reflections on the teaching. Intertextual discourse analysis was used to understand what scientific practices preservice teachers choose to integrate into their teaching experience. Our results showed that preservice teachers chose to focus on four aspects of scientific practices: (1) employing historical understanding of how the theory emerged, (2) encouraging the use of evidence to build up a theory, (3) observation and interpretation of data maps, and (4) collaborative practices in making up the theory. For each of these practices, we also looked at the common challenges faced by preservice teachers by using constant comparative analysis. We observed the practices that preservice teachers decided to use and the challenges they faced, which were determined by what might have come as in their personal history as learners. Therefore, in order to strengthen preservice teachers' background, college courses should be arranged to teach important scientific ideas through scientific practices. In addition, such practices should also reflect the authentic practices of earth scientists such as use of historical record and differentiating observation versus interpretation.     

The Case of One Child: Making the shift from personal knowledge to professionally informed practice

The present paper examines shifts in preservice students' understandings about teaching and learning as a consequence of developing a case study of an elementary-aged child. Data for this paper were gathered from 18 preservice students and included (a) admission statements, (b) responses to open-ended questions, with accompanying illustrations, regarding students' learning trajectory in relation to the child they studied, and (c) responses to a survey that asked students to contrast what they felt they understood at the end of the term as compared with what they thought they knew at the start of the term. In addition, six of the 18 students volunteered to participate in a more in-depth follow-up that involved a short interview. The present paper represents a preliminary exploration and begins with a discussion of the assumptions and theoretical framework guiding the analysis. Data are then presented and examined, after which the paper concludes with some recommendations for teacher educators.     

Preservice teachers’ thinking within a research-based framework: what informs decisions?

A research-based framework for teaching science is a heuristic tool used to help preservice teachers conceptualize many complexities of teaching while making explicit the strategy to use a research-based body of professional knowledge to inform instructional decision-making (Clough, 2003, Paper presented at the annual meeting of the Association for the Education of Teachers in Science, St. Louis, MO). Elementary preservice teachers frequently struggle to apply this knowledge to classroom decisions (Madsen, 2002, Paper presented at the annual meeting of the North Central Association for the Education of Teachers of Science, Bettendorf, IA). This study examined the effects of using a video case-analysis within an elementary science methods course focused on the development of a research-based framework. Students in two course sections completed a unit plan, and students in one section completed the video analysis. Video analysis students’ performance on an oral defense with the instructor was compared with oral defense performance from students in the unit plan group. Video analysis students outperformed their peers on questions related to how learning theories influence decisions of selecting content, explaining the use of questioning, and the use of self assessment strategies. Despite these differences, students in both groups still perceive teaching as primarily accomplished through activities and have difficulties understanding the critical role of the teacher in promoting student goals. This study raises issues regarding teachers’ knowledge development during preservice experiences.     

Strategies for counterresistance: Toward sociotransformative constructivism and learning to teach science for diversity and for understanding

This article reports on two types of resistance by preservice science teachers: resistance to ideological change and resistance to pedagogical change. The former has to do with the feelings of disbelief, defensiveness, guilt, and shame that Anglo-European preservice teachers experience when they are asked to confront racism and other oppressive social norms in class discussions. Resistance to pedagogical change has to do with the roles that preservice teachers feel they need to play to manage conflicting messages about what they are expected to do from their cooperating teachers (cover the curriculum and maintain class control) and from their university supervisors (implement student-centered, constructivist class activities), and about what they desire to do as emerging teachers. Although these two forms of resistance are closely linked, in the literature they are extensively reported separately. This study suggests a sociotransformative constructivist orientation as a vehicle to link multicultural education and social constructivist theoretical frameworks. By using this orientation, specific pedagogical strategies for counterresistance were found effective in helping preservice teachers learn to teach for diversity and understanding. These strategies for counterresistance were primarily drawn from the qualitative analysis of a yearlong project with secondary science preservice teachers. © 1998 John Wiley & Sons, Inc.

The Relationship Between Preservice Early Childhood Teachers’ Cultural Values and their Perceptions of Scientists’ Cultural Values

This paper describes research that compares preservice early childhood teachers’ cultural values and the values they believe are held by scientists. Using the Schwartz Values Inventory (SVI) (Schwartz (1992) Adv Exp Soc Psychol 25:331–351) preservice early childhood teachers cultural values were assessed, followed by an assessment of the values they believed were held by scientists. Schwartz postulated that cultural values could be aggregated into 11 domains (universalism, benevolence, tradition, self-direction, stimulation, hedonism, achievement, power, conformity, spirituality, and security). Paired T-tests indicated significant differences between preservice early childhood teachers’ cultural values from those they believed scientists held on the domains of power, achievement, stimulation, benevolence, conformity, and security. The discussion explores the meaning of these results and provides implications for early childhood science teacher education.     

PRESERVICE TEACHERS’ INSTRUCTIONAL BELIEFS AND EXAMINATION OF CONSISTENCY BETWEEN BELIEFS AND PRACTICES

The purposes of this study were to determine preservice physics teachers’ instructional beliefs and to investigate the relationship between their beliefs and practices. The theoretical framework was based on the combination Haney & McArthur’s (Science Education, 86(6):783–802, 2002) research and Ford’s (1992) motivation systems theory. A multicase study design was utilized for the research in order to focus on a belief–practice relationship within several examples. Semistructured interviews, observations, and preservice teachers’ written documents were used to collect data. Results showed that most preservice teachers held instructional beliefs aligned with constructivist philosophy. Some of the preservice teachers’ beliefs were consistent with their practices while some of them presented different practices from their beliefs in different placements.     

Too Close for Comfort: Real-Time Science Teaching Reflections via Digital Video Editing

This study examined the use of digital video editing as the main venue for fostering reflection. The impact of digital video editing technology on preservice teachers' beliefs included shifts in (a) reflections regarding children's thinking, (b) planning and instruction informed by reflection, and (c) notions of teaching expertise and requisite knowledge. Results were based on an instructional approach emphasizing the exploration of preservice teachers' own planning and teaching as they edited their own video accounts. These findings contrast typical video usage in teacher preparation in which teachers reflect upon the practice of others. Implications for teacher education programs and future research are discussed.     

Social constructivism and the <Emphasis Type="Italic">Believing Game</Emphasis>: a mathematics teacher’s practice and its implications

The study reported here is the third in a series of research articles (Harkness, S. S., D’Ambrosio, B., & Morrone, A. S.,in Educational Studies in Mathematics 65:235–254, 2007; Morrone, A. S., Harkness, S. S., D’Ambrosio, B., & Caulfield, R. in Educational Studies in Mathematics 56:19–38, 2004) about the teaching practices of the same university professor and the mathematics course, Problem Solving, she taught for preservice elementary teachers. The preservice teachers in Problem Solving reported that they were motivated and that Sheila made learning goals salient. For the present study, additional data were collected and analyzed within a qualitative methodology and emergent conceptual framework, not within a motivation goal theory framework as in the two previous studies. This paper explores how Sheila’s “trying to believe,” rather than a focus on “doubting” (Elbow, P., Embracing contraries, Oxford University Press, New York, 1986), played out in her practice and the implications it had for both classroom conversations about mathematics and her own mathematical thinking.     

Perceived Efficacy Beliefs of Prospective Nigerian Science Teachers

The purpose of this study was to assess differences between Nigerian junior and senior preservice teachers’ science teaching efficacy beliefs. Data in this study were collected from a total number of 221 preservice teachers enrolled in junior and senior secondary science teacher education programs in Nigeria using Science Teaching Efficacy Belief Instrument (STEB-B) (Enoch and Riggs in Sci Educ 74:625–638 1990). Results indicated that junior secondary preservice teachers were as efficacious as their senior secondary preservice teachers on the two dimensions of STEB-B. In addition, analyses did not reveal any significant gender differences on the two dimensions of STEB-B.     

Curriculum-Dependent and Curriculum-Independent Factors in Preservice Elementary Teachers’ Adaptation of Science Curriculum Materials for Inquiry-Based Science

In this nested mixed methods study I investigate factors influencing preservice elementary teachers’ adaptation of science curriculum materials to better support students’ engagement in science as inquiry. Analyses focus on two ‘reflective teaching assignments’ completed by 46 preservice elementary teachers in an undergraduate elementary science methods course in which they were asked to adapt existing science curriculum materials to plan and enact inquiry-based science lessons in elementary classrooms. Data analysis involved regression modeling of artifacts associated with these lessons, as well as in-depth, semester-long case studies of six of these preservice teachers. Results suggest that features of the existing science curriculum materials, including measures of how inquiry-based they were, have a relatively small influence on the preservice teachers’ curricular adaptations, while teacher-specific variables account for a much greater percentage of the variance. Evidence from the case studies illustrates the critical impact of the preservice teachers’ field placement contexts as an explanatory, teacher-specific factor in their curricular adaptations. These findings have important implications for science teacher educators and science curriculum developers, in terms of not only better understanding how preservice teachers engage with curriculum materials, but also how programmatic features of teacher education programs influence their ability to do so.     

Slowmation: Preservice elementary teachers representing science knowledge through creating multimodal digital animations

Research has identified the value of learners using technology to construct their own representations of science concepts. In this study, we investigate how learners, such as preservice elementary teachers, design and make a narrated animation to represent their science knowledge. The type of animation exemplified is called a “Slowmation” (abbreviated from “Slow Animation”), which is a simplified way for preservice teachers to make an animation that integrates features from claymation, object animation, and digital storytelling. Drawing on semiotic theory, a case study of three preservice elementary teachers, who were audio and video recorded as they created a slowmation, illustrates how the construction process enabled them to engage with a science concept in multiple ways. Findings suggest that when preservice teachers create a slowmation, they design and make a sequence of five representations, each being a semiotic system with particular affordances that link as a semiotic progression: (i) research notes; (ii) storyboard; (iii) models; and (iv) digital photographs, which culminate in (v) a narrated animation. In this study, the authors present their theoretical framework, explain how the preservice teachers created a slowmation using a sequence of representations to show their science knowledge and discuss the implications of these findings for learners in universities and schools. © 2011 Wiley Periodicals, Inc.

Exploring Preservice Elementary Teachers’ Understanding of the Essential Features of Inquiry-Based Science Teaching Using Evidence-Based Reflection

This study explored preservice elementary teachers' and their mentors' understanding of the essential features of inquiry-based teaching through the use of evidence-based reflection. The web-based video analysis tool (VAT) system was used to support preservice teachers' and mentors' evidence-based reflection during field experiences. Major data sources included VAT reflections and individual interviews. Data analysis indicated that the preservice teachers had been involved in various activities designed to support their understanding of inquiry features in a science methods class; they did not implement all of the features in their actual teaching. Both preservice teachers and mentors had difficulty connecting appropriate inquiry features to each teaching episode, which indicates their lack of understanding of inquiry. Both the preservice teachers and mentors had different levels of understanding for each feature. That is, they tended to understand certain features better than others. They interpreted each feature of inquiry-based science teaching too broadly. They also either had a teacher-centered view or tended to focus on issues unrelated to science teaching.     

Evaluation of Preservice Teachers’ Internships: A Model to Encourage Career Continuity and Program Reform

Quality teacher evaluation is a complex subject, requiring complex methods that draw from multiple data sources (Peterson, 2000). Most importantly, preservice teacher evaluation should match teacher education objectives (Popham, 1993) and, ultimately, be used to inform teacher practices and reform educational programming (Darling-Hammond, 1990). The purpose of this study is to present an evaluation model that uses multiple data sources for a preservice teacher’s internship experience. This model is employed within a teacher education program at a large land-grant university; the multiple data sources match program objectives and draw parallels between preservice and inservice teacher evaluation tools at use in this particular state. The evaluation model incorporates two guiding objectives within this college of education’s mission statement—objectives that focus on performance and reflection. First, preservice teachers are educated to assume roles of leadership and service in classroom practice, and second, preservice teachers are taught to become reflective practitioners, The first objective is measured by using a research-based classroom observation rating form during the internship that closely resembles the tool used by the state-licensing department of education. The second program objective is measured through the use of portfolios. In addition to using the results from these instruments to advise preservice teachers regarding their professional growth, the data can also guide program development within the college and suggest programmatic reform, an often overlooked yet integral factor of personnel evaluation. Discussion of specific rating results per instrument and specific avenues for program development are presented.     

Constructing videocases to help novices learn to facilitate discussions in science and English: how does subject matter matter?

Learning to conduct interactive classroom discussions is a high priority for becoming an effective teacher, and most teachers view conducting productive classroom discussions as a complex undertaking. Because the dynamics of facilitating classroom discussions are multifaceted and hard to analyze in real time, there is a growing interest in how video allows preservice teachers to examine records of their practice to promote further growth. What prospective teachers actually take away from analysis of video, however, needs further exploration. In this study, we explored five preservice student teachers’ beliefs about conducting discussions and probed the potential of videocase construction for supporting teacher learning by investigating the following question: ‘To what extent and how does making a videocase help preservice teachers investigate their facilitation of a subject‐specific discussion?’ Results revealed that by constructing and talking about their videocases, all five preservice teachers gained insights about how they lead discussions. Studying video excerpts and articulating what they saw in them provided a context for looking more closely at their own roles and student roles within their discussion. They also recognized the complexities of leading discussions and acknowledged particular areas that need improvement. The teachers used the metaphorical language of ‘guiding’ their students down a pathway when they talked about leading classroom discussions. There were similarities and differences among teachers’ conceptions of good discussions in English and science, and their notions of ‘guiding’ were related to their subject matter goals. The study suggests, however, several areas that may require further attention in preservice teachers’ preparation in leading discussions. Although the teachers expressed views of discussion that aligned broadly with disciplinary views in English or science, their language lacked specificity in what it means to develop varied interpretations of texts in English or consensus based on argument and evidence in science. More specific video analysis focused on subject matter goals and corresponding conversational elements may help preservice teachers develop more nuanced, sophisticated views of how particular types of social interaction have the potential to help their students reach specific subject matter goals. We conclude that investigation is needed on larger numbers of preservice teachers’ videocase construction processes, and further inquiry is needed into how working with video analysis affects their actual performance in future discussion facilitation.     

The Development and Validation of an Instrument to Measure Preservice Teachers' Self-Efficacy in Regard to The Teaching of Science as Inquiry

The purpose of this study was to develop, validate, and establish the reliability of an instrument that measures preservice teachers' self-efficacy in regard to the teaching of science as inquiry. The instrument, Teaching Science as Inquiry (TSI), is based upon the work of Bandura (1977, 1981, 1982, 1986, 1989, 1995, 1997), Riggs (1988), and Enochs and Riggs (1990). Self-efficacy in regard to the teaching of science as inquiry was measured through the use of a 69-item Likert-type scale instrument designed by the author of the study. Based on the standardized development processes used and the associated evidence, the TSI appears to be a content and construct valid instrument with high internal reliability for use with preservice elementary teachers to assess self-efficacy beliefs in regard to the teaching of science as inquiry.     

Re-situation challenges for international students ‘becoming’ researchers

This paper presents data generated during a semester-long programme to support international students from countries in Melanesia and Asia embarking on masters research in education in a New Zealand university. All were scholarship recipients. The researcher-and facilitator-of the programme, was interested in documenting and understanding the nature of the students’ experience as they planned and wrote research proposals. The process of developing a research proposal, as one of the early stages of ‘becoming’ a researcher, highlighted a number of challenges for the six case study students. The challenges are viewed from a transition or ‘resituation’ perspective (Eraut in Stud Contin Educ 26(2): 247–74, 2004, 2008) rather than an adjustment one. A resituation perspective assumes that students brought with them “personal expertise, practical wisdom and tacit knowledge” (Eraut 2008, p. 42) which needed to be reconciled with what was demanded of them by different aspects of the research planning process. The resituation challenges experienced by the students included situating a perceived problem or issue in the research literature; reconciling personal research goals with the limitations of one’s own agency as a researcher; integrating new learning with research goals; and reconciling the new role or identity as a researcher with the previous role as colleague or community member. The paper presents a case for providing a context for postgraduate students in which explicit recognition of what they bring to the research task, and acknowledgement of the resituation challenges can take place.     

Forms of Knowing Mathematics: What Preservice Teachers Should Learn

What important ideas about forms of knowing mathematics should be included in mathematics methods courses for preservice teachers? Ideas are proposed that are related to categories in Shulman's (1986) framework of teacher knowledge. There is a brief discussion of the implications each idea holds for teaching mathematics, and some suggestions are given about experiences that may help preservice teachers appreciate these notions. One portion of Shulman's pedagogical content knowledge construct is knowing what makes a subject difficult and what preconceptions students are apt to bring. Three of the ideas offered for inclusion in a methods course are related to this aspect of pedagogical content knowledge: (1) Understanding students' understanding is important, (2) Students knowing in one way do not necessarily know in the other(s), and (3) intuitive understanding is both an asset and a liability. The last two ideas, are related to the other portion of pedagogical content knowledge, knowing how to make the subject comprehensible to learners. These ideas are (4) certain characteristics of instruction appear to promote retention, and (5) providing alternative representations and recognizing and analyzing alternative methods are important. Readers are asked to consider if the suggestions offered are appropriate and how they might best be taught.     

Supporting teacher professional development through online video case study discussions: An assemblage of preservice and inservice teachers and the case teacher

The purpose of this study was to explore the potential value of online video case discussions among preservice and inservice teachers, and the video case teacher as a tool for the professional development of teachers. Participants included a total of 26 preservice and inservice mathematics teachers and a veteran teacher who appeared on the video case. Using content analysis techniques, we provided a thematic analysis of the teacher discourse and demonstrated the exchanges between the participating teachers and video case teacher. We also assessed the overall effectiveness of our online forum set up for the professional development of teachers. Results indicated that participant teachers were able to make theory–practice connections by articulating specific frameworks that guided our study. The inclusion of the video case teacher was beneficial for the other teachers in several ways. We contend that online forum discussions of video cases in which collective engagement of preservice and inservice teachers, and the case teacher have a great potential to support teacher professional development.     

Influence of perceptions: Listening to early childhood preservice teachers

Abstract

This qualitative study examined how the perceptions of preservice teachers influenced their developing teaching role, and how the perceptions of preservice teachers can be influenced by teacher preparation programs. The influences of perceptions are mostly unrecognized, but are significant to the teacher preparation process. Without identifying their perceptions about the teaching role, and explicitly enhancing or changing perceptions, preservice teachers may return unknowingly to their implicit perceptions when they begin teaching. Thus, their practices may or may not reflect what they have been taught about appropriate practices for young children. Suggestions are made to facilitate the learning of prospective teachers about the influence of their perceptions, and how they can begin the process of changing/enhancing their perceptions regarding the role of the practitioner. © 2001 Elsevier Science Inc.

Student connections among counting problems: an exploration using actor-oriented transfer

The purpose of this article is to explore student-generated connections among counting problems. The literature indicates that such problems pose difficulties for students, who struggle to detect common structures and identify models of underlying problem types. A case study is presented here, in which students elaborate upon connections they make during the problem solving process. The selected case study highlights student work on three particular combinatorics problems, one of which highlights tendencies toward over-counting. The conception of Lobato (Educational Researcher 3(1):17–20, 2003) of actor-oriented transfer, in which students’ (as opposed to experts’) notions of similarity are emphasized, is used as a means by which to analyze the resulting qualitative data. Results include (1) a domain-specific categorization of fundamental types of actor-oriented transfer in combinatorics and (2) implications that there is much to be gained when students attend to features of problems that experts might not emphasize.
