GLOBE: A Worldwide Environmental Science and Education Partnership   总被引:1,自引:1,他引:0  
The Global Learning and Observations to Benefit the Environment (GLOBE) Program is a unique hands-on international environmental science and education program designed for use in schools in Kindergarten through Grade 12. Continually growing, GLOBE to date involves students in almost 5000 schools in over 60 countries around the world. GLOBE students take environmental measurements selected by the world science community so as to provide data useful for research into the dynamics of the Earth's environment. GLOBE data is reported using the Internet/World Wide Web. Data from GLOBE schools all over the world are used to produce vivid displays and contour maps as immediate feedback helping students to appreciate the impact and context of their efforts. Other features of the GLOBE Web site allow GLOBE students to communicate and collaborate with scientists and with other GLOBE students around the world.  相似文献

In this study, we seek a better understanding of how individuals and their daily interactions shape and reshape social structures that constitute a classroom community. Moreover, we provide insight into how discourse and classroom interactions shape the nature of a learning community, as well as which aspects of the classroom culture may be consequential for learning. The participants in this study include two teachers who are implementing a new environmental science program, Global Learning through Observation to Benefit the Environment (GLOBE), and interacting with 54 children in an urban middle school. Both qualitative and quantitative data are analyzed and presented. To gain a better understanding of the inquiry teaching within classroom communities, we compare and contrast the discourse and interactions of the two teachers during three parallel environmental science lessons. The focus of our analysis includes (1) how the community identifies the object or goal of its activity; and (2) how the rights, rules, and roles for members are established and inhabited in interaction. Quantitative analyses of student pre‐ and posttests suggest greater learning for students in one classroom over the other, providing support for the influence of the classroom community and interactional choices of the teacher on student learning. Implications of the findings from this study are discussed in the context of curricular design, professional development, and educational reform. ? 2004 Wiley Periodicals, Inc.

The article presents results of the evaluation of the GLOBE program (Global Learning and Observations to Benefit the Environment) in the Czech Republic. The evaluation explores the implementation of the program in schools and its impact on research skills. Four hundred and sixty six pupils, aged 13, from 28 different schools participated in the evaluation. The evaluation revealed problems with the implementation of the program in schools. The majority of pupils usually collect data and work with worksheets in the program. The other activities, such as the analysis and comparison of collected data or planning GLOBE activities, are done only occasionally or never. Although one of the main goals of the program is to develop pupils' research skills, the program had no measurable effect on this outcome. According to these results, changes in the way the program is implemented are needed. Recommendations for further program development and evaluation are discussed.  相似文献

Student–teacher–scientist partnership (STSP) programs are cooperative relationships in which students, with the support of their teachers, participate in and contribute to the research of scientists. This paper examines one of the world's largest STSPs—an international environmental science education program called GLOBE (Global Learning and Observations to Benefit the Environment)—and proposes recommendations to scientists about how they can get the most out of their research and teaching relationship with students and their teachers. GLOBE is an international K–12 STSP that engages students in Earth's Systems investigations. Extensive training is needed for students to collect and report accurate data to scientists, and special preparatory curricula are needed to make their partnership effective and motivating. Recognizing these issues, this research was conducted specifically to identify and recommend a set of training material design criteria for implementation of STSPs in the elementary and middle school levels. The conclusions—the result of background research, extensive interviews and consultation with teachers—provide guidance to GLOBE and other STSP programs to enhance the development of effective and engaging training materials.  相似文献

The purpose of this study was to investigate the beliefs of six experienced high school science teachers about (1) what is successful science learning; (2) what are the purposes of laboratory in science teaching; and (3) how inquiry is implemented in the classroom. An interpretive multiple case study with an ethnographic orientation was used. The teachers' beliefs about successful science learning were substantively linked to their beliefs about laboratory and inquiry implementation. For example, two teachers who believed that successful science learning was deep conceptual understanding, used verification labs primarily to illustrate these concepts and used inquiry as a type of isolated problem‐solving experience. Another teacher who believed that successful science learning was enculturation into scientific practices used inquiry‐based labs extensively to teach the practices of science. Tension in competing beliefs sets and implications for reform are discussed. ? 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 936‐960, 2004.  相似文献

What are the barriers to technology‐rich inquiry pedagogy in urban science classrooms, and what kinds of programs and support structures allow these barriers to be overcome? Research on the pedagogical practices within urban classrooms suggests that as a result of many constraints, many urban teachers' practices emphasize directive, controlling teaching, that is, the “pedagogy of poverty” (Haberman, 1991 ), rather than the facilitation of students' ownership and control over their learning, as advocated in inquiry science. On balance, research programs that advocate standards‐based or inquiry teaching pedagogies demonstrate strong learning outcomes by urban students. This study tracked classroom research on a technology‐rich inquiry weather program with six urban science teachers. The teachers implemented this program in coordination with a district‐wide middle school science reform. Results indicated that despite many challenges in the first year of implementation, students in all 19 classrooms of this program demonstrated significant content and inquiry gains. In addition, case study data comprised of twice‐weekly classroom observations and interviews with the six teachers suggest support structures that were both conducive and challenging to inquiry pedagogy. Our work has extended previous studies on urban science pedagogy and practices as it has begun to articulate what role the technological component plays either in contributing to the challenges we experienced or in helping urban science classrooms to realize inquiry science and other positive learning values. Although these data outline results after only the first year of systemic reform, we suggest that they begin to build evidence for the role of technology‐rich inquiry programs in combating the pedagogy of poverty in urban science classrooms. © 2002 John Wiley & Sons, Inc.

In this investigation we employed a case study approach with qualitative and quantitative data sources to examine and discover the characteristics of the processes used by a midwestern U.S. school system to adopt and implement a new K–6 science curriculum. Analysis of data yielded several results. Elementary teachers received what they requested, a hands‐on science program with texts and kits. Teachers as a group remained in the early stages of the Concerns‐Based Adoption Model profile of concerns. Many K–6 teachers remained uncomfortable with teaching science. Teachers' attitudes regarding the new program were positive, and they taught more science. Teachers struggled with science‐as‐inquiry, with a science program they believe contained too many concepts and too much vocabulary, and with their beliefs that students learned more and loved the new hands‐on program. Traditional science teaching remained the norm. Administrative support was positive but insufficient to facilitate full implementation of the new program and more substantial change in teaching. Standardized science achievement test scores did not show an observable pattern of growth. It is concluded that a systematic, ongoing program of professional development is necessary to address teachers' concerns and help the district realize its goal of standards‐based K–6 science instruction. © 2004 Wiley Periodicals, Inc.

Teaching students how to conduct authentic scientific inquiry is an essential aspect of recent science education reform efforts. Our National Science Foundation-funded GK-12 program paired science graduate students—fellows—with secondary science teachers in order to enhance inquiry-based instruction. This research examined the roles of the fellows, teachers, and school culture in the implementation of inquiry and the fellows’ conceptions of classroom inquiry versus that in their own research. Qualitative data were collected for two academic years. Overall, the classrooms shifted toward a more inquiry-oriented approach over the academic year. Several aspects of school culture influenced inquiry implementation. Fellows described their research as similar in overall structure but less constrained by known concepts, less guided by mentors, and more in-depth than that of secondary school students. The teacher-fellow scientist partnership is a potentially effective professional development model to create positive and lasting change within the science classroom.  相似文献

A central concern in science education is promoting inquiry activities, and a significant amount of research in science education has addressed what inhibits this goal. However, this research has tended to be focused on implementation issues. Levels of implementation are correlated with extrinsic barriers such as time, resources and teacher knowledge, but the internal structure of inquiry remains unexamined. However, are there also some ways in which inquiry based instruction is intrinsically difficult? That is, given perfect conditions for implementation, is devising inquiry activities a non-trivial matter, and are there patterns to the difficulties in doing so? The aim of this paper is to provide both a theoretical and empirical basis for the intrinsic problems associated with the construction of inquiry activities. We present a theoretical framework that connects contemporary studies of science to the classroom context. We then examine a case study of teacher education students designing inquiry-based instruction to demonstrate empirical evidence of intrinsic problems. Our ultimate goal is to improve our ability as teacher educators to guide science teachers in fulfilling this central task of their work.  相似文献

This study provides psychometric data for the Scholastic Inquiry Observation instrument and 6 years of research data from an inquiry-based professional training program. The rating instrument provides a resource for measuring 16 inquiry-related learning activities based on level of inquiry implementation and level of active student engagement. Observational data at the item level can be useful for inquiry-based professional development programs. Four scale score options are available for inquiry summarization (Inquiry Implementation for Hypothesis Usage; Implementation of Inquiry Communication; Student Engagement in Hypothesis Usage; Student Engagement in Inquiry Communication) and two scales measuring Student Interest and Mastery of Objectives. Comparisons of the types of inquiry most commonly used and those with the highest levels of active participation by middle school students in science and math classrooms are provided.  相似文献

The impact of a professional development experience involving scientists and fourth to eighth grade teachers of science was explored. Teachers attended a summer program at a research facility where they had various experiences such as job shadowing and interviewing scientists. They also participated in authentic inquiry investigations and planned inquiry units for their classrooms. Data on teachers’ understanding and implementation of inquiry were collected through surveys, questionnaires, and classroom observations. Findings show that the teachers’ understanding of inquiry improved and most participants were able to successfully implement inquiry science in their classrooms. Barriers to the implementation of inquiry practices and the impact of specific experiences with the scientists were explored.  相似文献

As part of a larger project aimed at promoting science and literacy for culturally and linguistically diverse elementary students, this study has two objectives: (a) to describe teachers' initial beliefs and practices about inquiry‐based science and (b) to examine the impact of the professional development intervention (primarily through instructional units and teacher workshops) on teachers' beliefs and practices related to inquiry‐based science. The research involved 53 third‐ and fourth‐grade teachers at six elementary schools in a large urban school district. At the end of the school year, teachers reported enhanced knowledge of science content and stronger beliefs about the importance of science instruction with diverse student groups, although their actual practices did not change significantly. Based on the results of this first year of implementation as part of a 3‐year longitudinal design, implications for professional development and further research are discussed. © 2004 Wiley Periodicals, Inc.

Global Learning and Observations to Benefit the Environment (GLOBE) is an international science and environmental education program that enables school children to learn about the environment by taking scientific measurements of their natural surroundings and sharing their data with scientists via the Internet. By carefully following protocols and using approved measurement devices, students around the world are developing an archive of standardized data that can also be used in professional research. GLOBE is divided into several separate investigations, each focused on a different aspect of the environment. They include land cover, soil, hydrology, phenology, haze, and the atmosphere. Each investigation has a team of scientists who have worked with students and teachers to develop detailed protocols for the students to collect data. In addition, the scientists are exploring ways of using that data in their own research. This article is mostly about the work of GLOBE scientists—but also some students and teachers—in the first 5 years of the program. It is intended to provide an overview of the scientists' efforts to develop a meaningful learning experience around gathering environmental data for research.  相似文献

This study examined changes in middle school teachers’ beliefs about inquiry, implementation of inquiry practices, and self-efficacy to teach science through inquiry after participating in a year-long professional development program. The professional development model design was based on Bandura’s (1986) social cognitive theory of learning and literature on effective professional development. Using the Electronic Quality of Inquiry Protocol (EQUIP) before and after the program (Marshall, Smart & Horton, 2010), teachers’ quality of inquiry instruction significantly increased across all 4 EQUIP factors. To assess teachers’ inquiry teaching efficacy, the Teaching Science as Inquiry (TSI; Dira-Smolleck, 2004) instrument was administered 3 times to the teacher participants. Changes between time points of TSI administration were examined for personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. Findings for the personal self-efficacy scale showed statistically significant gains from pre-Institute to 1-year follow-up for all 5 inquiry features. Teachers’ outcome expectancy beliefs significantly increased across the program for 3 of the 5 essential features of inquiry. The results indicate the effectiveness of the professional development model at increasing the participants’ inquiry efficacy as well as the quality of their inquiry instruction. Our study provides evidence to support the need to include collaborative practice-teaching and reflection opportunities within professional development models that aim to increase teachers’ use of inquiry-based instructional strategies.  相似文献

The purpose of this study was to determine if teachers who participated in a professional development program continued to learn about inquiry and inquiry teaching as they implemented inquiry in their classrooms. A qualitative design utilizing inductive analysis was used to investigate teachers’ understanding and classroom implementation of inquiry. Findings are presented as assertions, drawing support from four focal teachers. For each assertion, confirming and disconfirming data are presented. Based on these data, we assert that a) there was little or no change in teachers’ individual understanding of inquiry, and b) professional development enhanced teachers’ ability to design inquiry-based activities – however, classroom implementation did not reflect a high level of inquiry.  相似文献

The purpose of this study was to investigate high school teachers’ beliefs about inquiry instruction and determine how their beliefs influenced their use of inquiry after a professional development program. Thirty-six high school science teachers participated in this study. The professional development program consisted of a 2-week summer institute as well as academic year support. The summer program included discipline-specific content lessons that utilized inquiry-based instruction, pedagogical practice involving the use of a summer high school enrichment program, and reflection on this practice-teaching in content area groups. Both in-depth qualitative interview and written reflection data were collected as well as data from the teachers’ classroom implementation of inquiry. Based on the analysis of the teachers’ interviews and classroom enactments, the teachers were placed into four enactment categories: Integrated, Emerging, Laboratory-based, and Activity-focused. We used Windschitl’s (Rev Educ Res 72(2):131–175, 2002) four constructivist dilemmas as a framework to understand the teachers’ enactments. We describe the teachers’ beliefs and practices in each enactment category as well as the components of the professional development model that were important to making changes in the teachers’ practices. In the conclusion, we connect the enactment levels to the professional development experience and suggest future directions for professional developers to move teachers toward more integrated inquiry practices.  相似文献

The study analyzes the meaning attributed to the GLOBE program by its former participants. The data were collected by conducting interviews with 19 adult respondents who left the program at least five years ago. The respondents interpreted the program as a strong community shaped by routine as well as extraordinary program activities and by their relationships. The respondents linked their GLOBE experience with the feeling of being part of something meaningful. The program provided them with a special privilege to experience something different from their non-participating peers. Their participation in the program influenced the respondents' future life and in some cases their professional career. The study discusses the implications in respect to environmental education practice.  相似文献

We present an inquiry‐based, aquatic science professional development (PD) for upper‐elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers’ characteristics and the grade band of the students. Our study lends support to the assertion that inquiry‐ and content‐focused PD, paired with classroom implementation, can effectively improve student learning. Our findings indicate that students improved in their nature of science (NOS) and aquatic science content knowledge and that these changes depended in some ways on the participating teachers’ characteristics and adherence to the program. The students’ improvements were amplified when their teachers adhered more closely to the PD activities during their classroom implementation. The teachers’ previous science PD experience and pre‐PD understanding of inquiry‐based teaching also explained some of the variability in student growth. In both NOS and content, students of teachers with less prior science‐PD experience benefited more. Grade band also explained variation in student outcomes through interactions with teacher‐characteristic variables. In high school, students of teachers with lower pre‐PD inquiry knowledge appeared to learn more about NOS. Our results suggest that inquiry and content training through PD may minimize disparities in teaching due to inexperience and lack of expertise. Our study also demonstrates the value of PD that teaches a flexible approach to inquiry and focuses on underrepresented, interdisciplinary content areas, like aquatic science. © 2017 Wiley Periodicals, Inc.

This study has two purposes: the first is to explore experienced science teachers’ perspectives on inquiry teaching, and the second is to categorize these perspectives into patterns. Fifteen junior high school science teachers experienced at inquiry teaching were selected, and a semi-structured interview was conducted to collect the teachers’ perspectives on inquiry and inquiry teaching. The findings indicate that these experienced science teachers hold multiple perspectives on inquiry and inquiry teaching. The two patterns generated from these teachers’ perspectives of inquiry and inquiry teaching were systematic-based inquiry instruction and learning-based inquiry instructions. Suggestions for science teacher educators are discussed in this paper.  相似文献

In the Budding Science and Literacy project, we explored how working with an integrated inquiry-based science and literacy approach may challenge and support the teaching and learning of science at the classroom level. By studying the inter-relationship between multiple learning modalities and phases of inquiry, we wished to illuminate possible dynamics between science inquiry and literacy in an integrated science approach. Six teachers and their students were recruited from a professional development course for the current classroom study. The teachers were to try out the Budding Science teaching model. This paper presents an overall video analysis of our material demonstrating variations and patterns of inquiry-based science and literacy activities. Our analysis revealed that multiple learning modalities (read it, write it, do it, and talk it) are used in the integrated approach; oral activities dominate. The inquiry phases shifted throughout the students' investigations, but the consolidating phases of discussion and communication were given less space. The data phase of inquiry seems essential as a driving force for engaging in science learning in consolidating situations. The multiple learning modalities were integrated in all inquiry phases, but to a greater extent in preparation and data. Our results indicate that literacy activities embedded in science inquiry provide support for teaching and learning science; however, the greatest challenge for teachers is to find the time and courage to exploit the discussion and communication phases to consolidate the students' conceptual learning.  相似文献
