This study aimed to assess grade 10 Turkish students' and science teachers' conceptions of nature of science (NOS) and whether these conceptions were related to selected variables. These variables included participants' gender, geographical region, and the socioeconomic status (SES) of their city and region; teacher disciplinary background, years of teaching experience, graduate degree, and type of teacher training program; and student household SES and parents' educational level. A stratified sampling approach was used to generate a representative national sample comprising 2,087 students and 378 science teachers. After establishing their validity in the Turkish context, participants were administered a questionnaire comprising 14 modified “Views on Science‐Technology‐Society” (VOSTS) items to assess their views of certain aspects of NOS. A total of 2,020 students (97%) and 362 teachers (96%) completed the questionnaire. Participant responses were categorized as “naïve,” “have merit,” or “informed,” and the frequency distributions for these responses were compared for various groupings of participants. The majority of participants held naïve views of a majority of the target NOS aspects. Teacher views were mostly similar to those of their students. Teacher and student views of some NOS aspects were related to some of the target variables. These included teacher graduate degree and geographical region, and student household SES, parent education, and SES of their city and geographical region. The relationship between student NOS views and enhanced economic and educational capitals of their households, as well as the SES status of their cities and geographical regions point to significant cultural (specifically Western) and intellectual underpinnings of understandings about NOS. © 2008 Wiley Periodicals, Inc.

This study examined the interrelationships among three major components of classroom teaching: subject matter content knowledge, classroom management, and instructional practices. The study involved two middle school science classes of different achievement levels taught by the same female teacher. The teacher held an undergraduate degree with a major in social studies and a minor in mathematics and science from an elementary teacher education program. The findings indicated that the teacher's limited knowledge of science content and her strict classroom order resulted in heavy dependence on the textbook and students' individual activities (e.g., seatwork) and avoidance of whole-class activities (e.g., discussion) similarly in both classes. Implications for educational practices and further research are discussed. 相似文献

This study investigates the effect of physics education on students' achievement in a large‐scale quantitative study of pre‐academic high school students throughout the Netherlands. Two aspects of teacher characteristics as perceived by their students are included: their “pleasantness” principally defined by their perceived friendliness and positive feedback and their “centeredness” principally defined by the perceived teacher centeredness in the lessons. Furthermore, this study includes four student aspects: their “general capability,” their “quantity of work,” their “quality of work,” and their “interest in the lessons.” Structural Equation Modeling is used in order to cluster the different variables defining the perceived pleasantness and the perceived centeredness of the teacher and the general capability, interest, and learning attitudes of the students. Furthermore, interrelations among these components and students' achievement are analyzed. Eventually, a very large effect of the students' general capability (61–72%) and a remarkably smaller effect of the remaining parameters (<3%) on achievement are detected. However, one should not yet conclude that teacher effect on high‐achieving‐students' achievement is consistently low. To the contrary, these results should be seen as an incentive to consider nonlinear effects, to vary ones viewpoint and to include more/other variables. In spite of the almost negligible correlation between the measured aspects of the physics teachers and achievement, the correlations between the teacher variables and the remaining student variables are quite significant. Both the perceived pleasantness and the centeredness of the teachers have a significant effect on the interest of their students. Furthermore, the pleasantness of the teacher correlates with the quality of the students' work and the centeredness of the teacher with their quantity of work. © 2012 Wiley Periodicals, Inc.

The purpose of this study was to characterise the development of a preservice physical education teacher's professional activity over the course of training interactions with her co‐operating teacher. The student teacher's professional development was studied using a hermeneutic and inductive approach based on the analysis of data from observation and self‐confrontation interviews. The results showed that the preservice teacher's conceptions regarding her teaching developed despite communication difficulties with her co‐operating teacher and that she constructed new knowledge—at times without her co‐operating teacher's awareness—even when she disagreed with him. However, the student teacher's classroom activity did not always change as a result of this new knowledge. The self‐confrontation interviews revealed her construction of knowledge, as well as the reasons for disagreement and her resistance to changing her classroom action. 相似文献

Abstract This study examined how six Singapore teachers approached the design and implementation of a unit of work (topic) to demonstrate exemplary classroom practices that engage learners and use ICT in knowledge-generative rather than presentational activities. After a reflection and feedback session on the first lesson observation involving the researcher and the teacher, the teacher redesigned the lesson to enhance ICT use and involve students more actively in their learning. Our study revealed that there is a difference between students' physical engagement and cognitive engagement in a task and that the teacher, as a designer of the learning environment, needs to make explicit the cognitive processes involved in using the tool to ensure students' effective use of ICT. The teachers' understanding of what constitutes effective learning and their roles in students' learning determine how they design the learning environment. In essence, it is the teacher's skill in managing the “tripartite” partnership of IT tool, learning task, and teacher support that brings about higher levels of student engagement. 相似文献

A model for analysing the nature of the dyadic teacher–student interplay in instructional situations including one teacher and one student is described. The “teacher” may be a regular teacher, a parent, or any other person who is in the position of teacher. The “student” may be a student of any age. The model may discern (a) if the teacher merely asks for information preknown to the teacher and the teacher evaluates the student's answer according to the teacher's preknowledge, (b) if the teacher asks for information preknown to the teacher, the teacher then scaffolds the student's learning by giving clues to the correct answer and then evaluates the answer according to the teacher's preknowledge, or (c) the teacher asks for information not preknown to her/him and the teacher is genuinely interested in the student's answer. This last scenario (c) is thought to give optimal conditions for cognitive development for the student. 相似文献

The theoretical construct of teacher noticing has allowed mathematics teacher educators to examine teacher thinking and practice by looking at the range of activities that teachers notice in the classroom. Guided by this approach to the study of teacher thinking, the central goal of this exploratory study was to identify what prospective science teachers notice when evaluating evidence of student understanding in another teacher's inquiry‐based unit. Our results are based on the qualitative analysis of 43 prospective teachers' evaluations of assessment evidence presented to them in the form of a video case and associated written artifacts. Analysis of our data revealed two major categories of elements, Task‐General and Task‐Specific, noticed by our study participants. Task‐General elements included attention to learning objectives, independent student work, and presentation issues and they often served to guide or qualify the specific inquiry skills that were evaluated. Task‐Specific elements included the noticing of students' abilities to perform different components of an investigation. In general, study participants paid attention to important general and specific aspects of student work in the context of inquiry. However, they showed preferential attention to those process skills associated with designing an investigation versus those practices related to the analysis of data and generation of conclusions. Additionally, their interpretations of assessment outcomes were largely focused on the demonstration of general science process skills; much less attention was paid to the analysis of the epistemological validity or scientific plausibility of students' ideas. Our results provide insights into the design of meaningful learning experiences for prospective teachers that elicit, challenge, and enrich their conceptions of student understanding in the context of inquiry. © 2013 Wiley Periodicals, Inc.

We set out to understand how different instantiations of inquiry emerged in two different years of one elementary teacher's classroom. Longitudinal observations from Mrs. Charles' 5th grade science classroom forced us to carefully and deliberately consider who exactly was responsible for the change in the class activities and norms. We provide empirical evidence to show how a focus on the teacher can easily overlook the complex dynamics of the classroom. The data reveal that students had a substantive and generative role in the class's arrival at the different instantiations of scientific inquiry—the nature and form of inquiry—that were constructed each year. We argue that, in an environment where a teacher carefully attends and responds to student thinking, the nascent resources students have for reasoning about phenomena can affect not only the conceptual ideas that emerge, but also influence what inquiry activities or practices become established as normative and productive over time. Our work with Mrs. Charles illuminates an important methodological concern with research on teacher development as well as the construct of teacher learning progressions; research accounts that focus primarily on the teacher may overlook the classroom norms that are negotiated between teacher and student, and thereby provide an incomplete portrayal of the teacher's activity within one classroom and the teacher's progress across multiple years. © 2012 Wiley Periodicals, Inc.

A study of students' identities as writers was carried out in the classroom of a New Zealand primary teacher who had been formally identified by a national body of teachers as having excellent practice in supporting literacy acquisition. The researchers, Professor Janice Wearmouth, from the University of Bedfordshire, Mere Berryman, from the University of Waikato, New Zealand, and Lisa Whittle, from the Department of Conservation, Wellington, New Zealand, aimed to compare high and low literacy achievers' identities as writers within the context of this teacher's pedagogy and the learning environment of her classroom. The researchers concluded that all students, both high and low achievers, were developing very positive writing identities in a context where the teacher's method of supporting her students' writing was very well planned through a process‐writing approach. This teacher had a very high degree of subject and pedagogical content knowledge and an acute awareness of her students' literacy learning needs. Her approach had an immediacy of responsiveness in relation to every student's learning and, above all, had recognition of the overwhelming importance of positive relationships in the classroom, teacher to student and peer to peer. 相似文献

The purpose of this study was to investigate the differences among schools using student responses in the Trends in Mathematics and Science Study–1999 (TIMSS‐99) data. Schools were classified into two groups based on eighth grade students' overall achievement in science. Two different discriminant function analyses were performed to distinguish high‐ and low‐performing schools, based both on classroom practices and factor structures (student‐centered activities, teacher‐centered activities, attitudes toward technology use, socioeconomic status [SES], and doing well in science). The results indicate that there were significant differences between the two classifications of schools on ten variables regarding classroom practices and activities, and 29 variables regarding classroom practices, attitudes toward science, use of the computer and overhead projector (OHP), parental background characteristics, and need to do well in science. Contrary to general expectations, technology use (computer, OHP, etc.) was found to be negatively related to science achievement. Teachers should be trained on how to use technology in their classrooms. Turkey recently revised its curriculum to a student‐centered approach and this might increase students' ability to transfer knowledge into real life. Teachers and schools should pay more attention to SES effects. Teachers should also work toward building students' confidence in science. © 2007 Wiley Periodicals, Inc.

This case study explored the nature of one elementary school teacher's adaptive teaching during an integrated science and literacy unit. Data were collected during four consecutive weeks of instruction, weekly interactive planning sessions, 20 classroom observations, and 20 post-lesson interviews. Our analysis suggests that adaptations may be established during planning or emerge while teaching. This study also indicated that an adaptive teacher uses ongoing formative assessment to scaffold students' learning. A coding system that typifies how and why a teacher adapts instruction across disciplines can be used to examine adaptive teaching. Implications for teacher educators and researchers are discussed. 相似文献

This case study focused on a preservice teachers' (Morgan) efforts to explicitly emphasize nature of science (NOS) elements in her first‐grade internship classroom. The study assessed the change in first grade students' views of the inferential, tentative, and creative NOS as a result of the explicit instruction. Morgan held appropriate views of NOS, had the intention and motivation to teach NOS, and had a supporting experience explicitly emphasizing NOS embedded in physics content to peer college students. Data sources included weekly classroom observations of explicit NOS science lessons taught by Morgan, interview of Morgan to determine that her views of NOS were informed and that she would have the NOS content knowledge to teach in line with recommended reforms, and interviews of the first‐grade students pre‐ and postinstruction to determine the influence of Morgan's instruction on their views of observation and inference, the tentative NOS, and the creative and imaginative NOS. Data were analyzed to determine (a) the approaches Morgan used to emphasize NOS in her instruction, and (b) students' views of NOS pre‐ and postinstruction to track change in their views. It was found that Morgan was able to explicitly emphasize NOS using three teacher‐designed methods, and that the influence on student views of the inferential, tentative, and creative NOS was positive. Implications for teacher development are provided. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 377–394, 2006 相似文献

This article is a case study of the thinking and actions of Mr. Corrigan, an experienced high school chemistry teacher. We explored Corrigan's ideas on teaching science by conducting two types of interviews, and wrote a case summary for Corrigan to read that compared his ideas with our classroom observations. We described his practice as centering on structured classroom and laboratory time, and contrasted it with his emphasis on students' exploratory thinking in the interviews. Corrigan's reflections on the case summary revealed a set of tacit conceptions of teaching science centered on the necessity of having a highly organized classroom and laboratory to ensure students' content understanding and success on tests and in college. We felt Corrigan faced a dilemma in that he values both his control of learning activities and the students' learning through exploration. Corrigan was confident in his practice and did not see much of a dilemma, and felt he was attending to both aspects of his thinking in an adequate fashion. Corrigan's reflections on the case summary are presented as a commentary on our perspective of the relationship between his thinking and actions. Working with Corrigan revealed to us the complexity of characterizing a teacher's thinking and its relationship to actions, and the value of the insight researchers gain from discussing their conclusions with the teacher. © 1997 John Wiley & Sons, Inc.

Neuroscientific and developmental psychological research in imitation has yielded important insights into building teacher–student relationships and enhancing students' learning. This study investigated the effects of reciprocal imitation on teacher–student relationships and students' learning outcomes in one‐on‐one teacher–student interactions. In a within‐subjects design, participants learned eight English vocabulary words under two conditions: one condition paired with teacher's imitative behaviors and the other with teacher's random behaviors. Students' self‐rating surveys and quiz scores on new words were assessed. When the teacher imitated the students' behaviors in interactions, the students reported significantly higher perceptions of rapport, more confidence in and satisfaction with learning outcomes, and had significantly higher quiz scores. Results had important implications for teachers in using imitation as an effective teaching tool to build teacher–student relationships and enhance students' learning. 相似文献

Historically there have been many claims made about the value of laboratory work in schools, yet research shows that it often achieves little meaningful learning by students. One reason, among many, for this failing is that students often do not know the “purposes” for these tasks. By purposes we mean the intentions the teacher has for the activity when she/he decides to use it with a particular class at a particular time. This we contrast with the “aims” of a laboratory activity, the often quite formalised statements about the intended endpoint of the activity that are too often the “opening lines” of a student laboratory report and are simply the “expected” specific science content knowledge outcomes—not necessarily learnt nor understood. This paper describes a unit of laboratory work which was unusual in that the teacher's purpose was to develop students' understanding about the way scientific facts are established with little expectation that they would understand the science content involved in the experiments. The unit was very successful from both a cognitive and affective perspective. An important feature was the way in which students gradually came to understand the teacher's purpose as they proceeded through the unit. © 2000 John Wiley & Sons, Inc.

This study assessed the influence of a 3‐year professional development program on elementary teachers' views of nature of science (NOS), instructional practice to promote students' appropriate NOS views, and the influence of participants' instruction on elementary student NOS views. Using the VNOS‐B and associated interviews the researchers tracked the changes in NOS views of teacher participants throughout the professional development program. The teachers participated in explicit–reflective activities, embedded in a program that emphasized scientific inquiry and inquiry‐based instruction, to help them improve their own elementary students' views of NOS. Elementary students were interviewed using the VNOS‐D to track changes in their NOS views, using classroom observations to note teacher influences on student ideas. Analysis of the VNOS‐B and VNOS‐D showed that teachers and most grades of elementary students showed positive changes in their views of NOS. The teachers also improved in their science pedagogy, as evidenced by analysis of their teaching. Implications for teacher professional development programs are made. © 2006 Wiley Periodicals, Inc.

This paper shows that high school math and science teacher gender affects student interest and self-efficacy in STEM. However, such effects become insignificant once teacher behaviors and attitudes are taken into account, thus pointing towards an omitted variables bias. Teacher beliefs about male and female ability in math and science – as well as how teachers treat boys and girls in the classroom – matter more than teacher's own gender. The student fixed effects estimates also highlight that creating a positive learning environment and making math and science interesting are pivotal in engaging students in these subjects. 相似文献

Abstract This article examines the social nature of teachers' conceptions by showing how teachers frame the “mismatch” of students' perceived abilities and the intended school curriculum through conversational category systems. This study compares the conversations of 2 groups of high school mathematics teachers addressing the Mismatch Problem when implementing equity-geared reforms. Although East High teachers challenged conceptions that were not aligned with a reform, South High teachers reworked a reform mandate to align with their existing conceptions. This research found that the teachers' conversational category systems modeled problems of practice; communicated assumptions about students, subject, and teaching; and were ultimately reflected in the curriculum. Because East High teachers supported greater numbers of students' success in advanced mathematics, this study considers the relation between teachers' understandings of student learning and the success of equity-geared math reforms. In addition, this study contributes to the understanding of how teacher conceptions of students are negotiated and reified in context, specifically through interactions with colleagues and experiences with school reform. 相似文献
