Grade 10 students' perceptions of classroom practices and activities, as well as their attitudes toward science teaching and school science, were assessed in the Westend School District (pseudonym) in British Columbia, using both quantitative (statistics of Likert-type scales) and qualitative (critical interpretive analysis of interview data) methods. The major findings of the study were that students do not appreciate the most prevailing contemporary practices in science classes, perceived by them as mainly the copying of the teacher's notes, and that they prefer science teaching and learning in which they take an active and responsible part. Additionally, teaching style appears to be the major determinant of high school students' attitudes toward science and science teaching. No change in students' perceptions of and attitudes toward science teaching and school science (in 1989 compared with 1986) could be detected in spite of the impact made by the recently advocated constructivist and science-technology-society (STS) approaches on science curriculum and science education. It is argued, therefore, that more emphasis must be placed on the science teachers' role and their teaching style if an educational change in the constructivist/STS direction is to be achieved.  相似文献

Sexual health is a controversial science topic that has received little attention in the field of science education, despite its direct relevance to students' lives and communities. Moreover, research from other fields indicates that a great deal remains to be learned about how to make school learning about sexual health influence the real‐life choices of students. In order to provide a more nuanced understanding of young people's decision‐making, this study examines students' talk about sexual health decision‐making through the lens of identities. Qualitative, ethnographic research methods with twenty 12th grade students attending a New York City public school are used to illustrate how students take on multiple identities in relation to sexual health decision‐making. Further, the study illustrates how these identities are formed by various aspects of students' lives, such as school, family, relationships, and religion, and by societal discourses on topics such as gender, individual responsibility, and morality. The study argues that looking at sexual health decision‐making—and at decision‐making about other controversial science topics—as tied to students' identities provides a useful way for teachers and researchers to grasp the complexity of these decisions, as a step toward creating curriculum that influences them. © 2010 Wiley Periodicals, Inc.

The purpose of this study was to construct and study the impact of a research‐based sequence for teaching the concept of modelling to seventh‐grade science students. We identified students' notions of models and the aspects of school science to be addressed regarding the model concept, which were then taken into account when we planned the learning sequence. The idea of modelling in science was taught while the students were learning about the change of states of matter in seventh‐grade physics. A pre‐interview revealed that the students' notions of models were very limited, while a post‐interview showed that this improved in the course of the series of lessons. There was also a statistically significant difference in the students' understanding of modelling between our target group and a control group consisting of ninth‐grade students who had received only the normal teaching. However, a delayed post‐questionnaire completed a few months after the teaching sequence showed that the stability of learning results were dependent on whether models and modelling were used in the normal teaching conducted after the teaching sequence. Implications for teaching, teacher education and research are also addressed in this paper.  相似文献

One of the main objectives of many science educators is to enroll students into science majors and careers. Researchers have investigated students' views of science in terms of factors and influences that guide students to choose science as a career. However, few investigations exist that have studied the forms of language culture makes available for articulating possible careers generally or the ways of grounding (justifying) these possibilities particularly. The purpose of this study is to investigate ways of using language for supporting justifications of career choices in an interview situation. Thirteen high school biology students were interviewed about their career choices. Drawing on discursive psychology as theory and method, we identify four interpretative repertoires that are deployed during the interviews: the (a) formative, (b) performative, (c) consequent, and (d) potential repertoires. These interpretative repertoires do not merely characterize the discourse about different science‐related professions but in fact co‐articulate different science‐related identities. © 2009 Wiley Periodicals, Inc.

Learning environment,motivation, and achievement in high school science   总被引:1,自引:0,他引:1  
In a study of the relationship between high school students' perceptions of their science learning environments and their motivation, learning strategies, and achievement, 377 students in 22 introductory science classrooms completed surveys in the fall and spring of their ninth‐grade year. Hierarchical linear regression was used to model the effects of variables at both the classroom and individual level simultaneously. High intraclass agreement (indicated by high parameter reliability) on all classroom environment measures indicated that students shared perceptions of the classroom learning environment. Controlling for other factors, shared perceptions that only the most able could succeed in science classrooms and that instruction was fast‐paced and focused on correct answers negatively predicted science achievement, as measured on a districtwide curriculum‐linked test. Shared perceptions that classrooms focused on understanding and independent thinking positively predicted students' self‐reported satisfaction with learning. Implications of these results for both teaching and research into classroom environments are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 347–368, 2003  相似文献

This article provides some stories of primary school teachers' and students' experiences of implementing new science teaching and learning strategies through an action research process that have also led to more environmental education occurring in the schools' curriculum. The stories have been constructed from the coordinators' journals, observations and interviews with the teachers and students in the schools. The teachers in the schools are consciously engaged in an action research-based model of curriculum change in science teaching and learning. The stories also acknowledge the critiques of critical theory in environmental education and the possibilities for a socially critical approach in environmental education within a context of the limited opportunities for both science and environmental education in primary schools.  相似文献

Recent research reveals that students' interest in school science begins to decline at an early age. As this lack of interest could result in fewer individuals qualified for scientific careers and a population unprepared to engage with scientific societal issues, it is imperative to investigate ways in which interest in school science can be increased. Studies have suggested that inquiry learning is one way to increase interest in science. Inquiry learning forms the core of the primary syllabus in Singapore; as such, we examine how inquiry practices may shape students' perceptions of science and school science. This study investigates how classroom inquiry activities relate to students' interest in school science. Data were collected from 425 grade 4 students who responded to a questionnaire and 27 students who participated in follow-up focus group interviews conducted in 14 classrooms in Singapore. Results indicate that students have a high interest in science class. Additionally, self-efficacy and leisure-time science activities, but not gender, were significantly associated with an increased interest in school science. Interestingly, while hands-on activities are viewed as fun and interesting, connecting learning to real-life and discussing ideas with their peers had a greater relation to student interest in school science. These findings suggest that inquiry learning can increase Singaporean students' interest in school science; however, simply engaging students in hands-on activities is insufficient. Instead, student interest may be increased by ensuring that classroom activities emphasize the everyday applications of science and allow for peer discussion.  相似文献

The development of scientifically literate citizens remains an important priority of science education; however, growing evidence of students' disenchantment with school science continues to challenge the realization of this aim. This triangulation mixed methods study investigated the learning experiences of 152 9th grade students as they participated in an online science‐writing project on the socioscientific issue of biosecurity. Students wrote a series of hybridized scientific narratives, or BioStories, that integrate scientific information about biosecurity with narrative storylines. The students completed an online Likert‐style questionnaire, the BioQuiz, which examined selected aspects of their attitudes toward science and science learning, prior to their participation in the project, and upon completion of the writing tasks. Statistical analyses of these results and interview data obtained from participating students suggest that hybridized writing about a socioscientific issue developed more positive attitudes toward science and science learning, particularly in terms of the students' interest and enjoyment. Implications for research and teaching are also discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 878–900, 2011  相似文献

Grade 10 high school students' understanding of the mechanisms of inheritance was explored following a course of instruction. A partially standardized interview procedure was developed based on inheritance concepts and propositions which were considered necessary for an understanding of inheritance. Concepts and propositions that were understood, not understood, or misunderstood were identified. Analysis of interviews from 48 students revealed several important implications for science curriculum writers and science teachers of grade 10 genetics topics.  相似文献

Recent instructional reforms in science education aim to change the way students engage in learning in the discipline, as they describe that students are to engage with disciplinary core ideas, crosscutting concepts, and the practices of science to make sense of phenomena (NRC, 2012). For such sensemaking to become a reality, there is a need to understand the ways in which students' thinking can be maintained throughout the trajectory of science lessons. Past research in this area tends to foreground either the curriculum or teachers' practices. We propose a more comprehensive view of science instruction, one that requires attention to teachers' practice, the instructional task, and students' engagement. In this study, by examining the implementation of the same lesson across three different classrooms, our analysis of classroom videos and artifacts of students' work revealed how the interaction of teachers' practices, students' intellectual engagement, and a cognitively demanding task together support rigorous instruction. Our analyses shed light on their interaction that shapes opportunities for students' thinking and sensemaking throughout the trajectory of a science lesson. The findings provide implications for ways to promote rigorous opportunities for students' learning in science classrooms.  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.

Many state and federal governments have mandated in such documents as the National Science Education Standards that inquiry strategies should be the focus of the teaching of science within school classrooms. The difficult part for success is changing teacher practices from perceived traditional ways of teaching to more inquiry‐based approaches. Arguments are often made about the effectiveness of these traditional strategies. The purpose of this study was to compare the effectiveness of the inquiry‐based approach known as the Science Writing Heuristic approach as a treatment to traditional teaching practices on students' post‐test scores in relation to students' achievement level and teacher's implementation of the approach. A mixed‐method research approach was used to analyze the teacher observational data and students' test results. The major findings of this study are that the quality of the implementation does have an impact on student performance on post‐test scores and that high‐quality implementation of the Science Writing Heuristic approach has significant advantages in closing the achievement gap within science classrooms.  相似文献

This paper presents an analysis of how affordances of ICT‐rich environments identified from a recent review of the research literature can support students in learning science in schools within a proposed framework for pedagogical practice in science education. Furthermore other pedagogical and curriculum innovations in science education (promoting cognitive change, formative assessment and lifelong learning) are examined to see how they may be supported and enhanced by affordances of ICT‐rich environments. The affordances that I have identified support learning through four main effects: promoting cognitive acceleration; enabling a wider range of experience so that students can relate science to their own and other real‐world experiences; increasing students' self‐management; and facilitating data collection and presentation. ICT‐rich environments already provide a range of affordances that have been shown to enable learning of science but integrating these affordances with other pedagogical innovations provides even greater potential for enhancement of students' learning.  相似文献

This paper reports the findings from a study of teachers and students' views regarding self‐worth in the primary school learning environment. The revised New Zealand curriculum recognises the importance of self‐worth in students' motivation and ability to learn. While the need to enhance self‐worth in the classroom has been well established in the literature, similarities and differences between teachers and students' understanding of the impact of various classroom interactions on self‐worth has not received the same attention. The purpose of the research reported on in this paper was to provide further insight for teachers, thereby enabling them to strengthen classroom relationships and their students' learning experiences in ways commensurate with enhancing students' feelings of self‐worth.  相似文献

In recent years, a number of curriculum reform projects have championed the notion of having students do science in ways that move beyond hands‐on work with authentic materials and methods, or developing a conceptual grasp of current theories. These reformers have argued that students should come to an understanding of science through doing the discipline and taking a high degree of agency over investigations from start to finish. This stance has occasionally been mocked by its critics as an attempt to create “little scientists”—a mission, it is implied, that is either romantic or without purpose. Here, we make the strong case for a practice‐based scientific literacy, arguing through three related empirical studies that taking the notion of “little scientists” seriously might be more productive in achieving current standards for scientific literacy than continuing to refine ideas and techniques based on the coverage of conceptual content. Study 1 is a classroom case study that illustrates how project‐based instruction can be carried out when teachers develop guidance and support strategies to bootstrap students' participation in forms of inquiry they are still in the process of mastering. Study 2 shows how sustained on‐line work with volunteer scientists appears to influence students' success in formulating credible scientific arguments in written project reports following an authentic genre. Study 3, using data from three suburban high school classes, suggests that involving students in the formulation of research questions and data analysis strategies results in better spontaneous use of empirical data collection and analysis strategies on a transfer task. The study also suggests that failing to involve students in the formulation of research can result in a loss of agency. The implications of these findings for future research and practice are discussed. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 234–266, 2004  相似文献

This study has two purposes: (a) methodological—to design and test a new instrument able to reflect changes in attitudes toward science over time, and (b) investigative—to find out the effect of two similar curricular treatments on the attitudes of two classes. Items about the relevance of science to students' lives were developed, pilot‐tested, and analyzed using Rasch modeling. We then divided reliable items into three equivalent questionnaire forms. The final three forms of the questionnaire were used to assess high school students' attitudes. Over 18 weeks, one class used a core curriculum (Science and Sustainability) to learn science in the context of making decisions about societal issues. A second class used the same core curriculum, but with parts replaced by computer‐based activities (Convince Me) designed to enhance the coherence of students' arguments. Using traditional and Rasch modeling techniques, we assessed the degrees to which such instructional activities promoted students' beliefs that science is relevant to them. Both classes tended to agree more, over time, that science is relevant to their lives, and the increases were statistically equivalent between classes. This study suggests that, by using innovative, issue‐based activities, it is possible to enhance students' attitudes about the relevance of science. © 2003 Wiley Periodicals, Inc.

Teaching science as explanation is fundamental to reform efforts but is challenging for teachers—especially new elementary teachers, for whom the complexities of teaching are compounded by high demands and little classroom experience. Despite these challenges, few studies have characterized the knowledge, beliefs, and instructional practices that support or hinder teachers from engaging their students in building explanations. To address this gap, this study describes the understandings, purposes, goals, practices, and struggles of one third-year elementary teacher with regard to fostering students' explanation construction. Analyses showed that the teacher had multiple understandings of scientific explanations, believed that fostering students' explanations was important for both teachers and students, and enacted instructional practices that provided opportunities for students to develop explanations. However, she did not consistently take up explanation as a goal in her practice, in part because she did not see explanation construction as a strategy for facilitating the development of students' content knowledge or as an educational goal in its own right. These findings inform the field's understanding of teacher knowledge and practice with regard to one crucial scientific practice and have implications for research on teachers and inquiry-oriented science teaching, science teacher education, and curriculum materials development.  相似文献

The teaching of science through activities that emphasize design and technology has been advocated as a vehicle for accomplishing science for all students. This study was situated in an inner7‐city neighborhood school populated mainly by African American students from life worlds characterized by poverty. The article explores the discourse and practices of students and three coteachers as a curriculum was enacted to provide opportunities for students to learn about the physics of motion through designing, building, and testing a model car. Some students participated in ways that led to their building viable model cars and interacting with one another in ways that suggest design and technological competence. However, there also was evidence of resistance from students who participated sporadically and refused to cooperate with teachers as they endeavored to structure the environment in ways that would lead to a deeper understanding of science. Analysis of in‐class interactions reveals an untapped potential for the emergence of a sciencelike discourse and diverse outcomes. Among the challenges explored in this article is a struggle for respect that permeates the students' lives on the street and bleeds into the classroom environment. Whereas teachers enacted the curriculum as if learning was the chief goal for students, it is apparent that students used the class opportunistically to maintain and earn the respect of peers. © 2001 John Wiley & Sons, Inc.
