GLOBE—The Science Behind Launching an International Environmental Education Program

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.     

Tools for Successful Student–Teacher–Scientist Partnerships

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.     

GLOBE: A Worldwide Environmental Science and Education Partnership

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.     

An integrated classification method for thematic mapper imagery of plain and highland terrains

The classification of thematic mapper imagery in areas with strong topographic variations has proven problematic in the past using a single classifier, due to the changing sun illumination geometry. This often results in the phenomena of identical object with dissimilar spectrum and different objects with similar spectrum. In this paper, an integrated classification method that combines a decision tree with slope data, tasseled cap transformation indices and maximum likelihood classifier is introduced, to find an optimal classification method for thematic mapper imagery of plain and highland terrains. A Landsat 7 ETM＋ image acquired over Hangzhou Bay, in eastern China was used to test the method. The results indicate that the performance of the integrated classifier is acceptably good in comparison with that of the existing most widely used maximum likelihood classifier. The integrated classifier depends on hypsography （variation in topography） and the characteristics of ground truth objects （plant and soil）. It can greatly reduce the influence of the homogeneous spectrum caused by topographic variation. This integrated classifier might potentially be one of the most accurate classifiers and valuable tool for land cover and land use mapping of plain and highland terrains.     

Making Inquiry a Habit of Mind: Learning to use inquiry to understand and improve practice

This study examines how student teachers in a 2-year graduate program used inquiry to examine the day-to-day issues that arose in their student teaching placements. Through systematic questioning, collection of data and controlled experimenting with solutions, student teachers learned to apply the technical and theoretical knowledge they were learning in education classes to their individual student teaching situations. Essential to the success of this process was collaboration with colleagues for clarifying their questions and for understanding and analyzing the data they collected. Analysis of the data shows that student teachers learned to help one another so that their teaching was focused and successful in many different ways. Confirmation of this success was noted in the supervisor evaluations and observation notes for each student teacher. Student teachers did learn to make inquiry a habit of mind, thereby initiating a long-term commitment to professional self-study.     

Greater expectations: Learning from other nations in the quest for 'world-class standards' in US school mathematics and science

This study examines teachers’ experiences with and opinions on a web‐based, cross‐cultural project. Students from the Czech Republic, Denmark, Macedonia, and Sweden used information and communication technology and international collaboration to explore the links among youth, culture, and the use of alcohol. The data was generated through interviews with the teachers co‐ordinating the project in each of the classes. The teachers’ experiences with the approach as a whole led them to emphasize that the action‐oriented and participatory approach, combined with the use of information and communication technology and international collaboration, brought new, valuable perspectives to their own teaching and to their reflections about emerging new roles and teaching skills needed. The provisions for genuine student participation, authenticity in learning, intrinsic motivation, and the sense of the other were identified by the teachers as the main strengths of the approach.     

Teacher collaboration in the context of the Responsive Classroom approach

This mixed‐method study examined characteristics and predictors of teacher collaboration. Limited research exists that describes the characteristics of teacher collaboration, and surprisingly little work explains the ways in which teaching experience and teachers’ perceptions of the school environment influence teacher collaboration. Questionnaire data were collected from a sample of 118 elementary school teachers in six schools in a northeast urban school district, and interviews were conducted with administrators in each school. Three schools were in their second year implementing the Responsive Classroom ^® (RC) approach, and three schools were comparison schools. Teachers reported collaborating approximately once or twice per month, generally with fellow grade‐level teachers about student‐centered topics. Teachers in RC schools reported more frequent formal collaboration than comparison school teachers. In regards to predicting teacher collaboration, teachers who used more RC practices and/or resources reported collaborating more, valuing collaboration to a higher degree, and perceiving greater involvement in school decision‐making, controlling for whether they taught at a RC school. Also, teachers’ perceptions of the school environment related positively to teacher collaboration. The current study adds to the understanding of teacher collaboration and its antecedents, contributing uniquely to the literature on how a school‐wide educational initiative is associated with teachers’ perceptions of their school environment as well as their collaborative behaviors and beliefs.     

Analysis of the K‐12 component of the Central Arizona–Phoenix Long‐Term Ecological Research (CAP LTER) project 1998 to 2002

The Central Arizona–Phoenix Long‐Term Ecological Research (CAP LTER) project includes training elementary and secondary teachers. This training component, Ecology Explorers (EE), prepares teachers in grades 4 through 12 to teach about ecological principles and processes. The EE pedagogy employs scientific inquiry and data collection protocols. This study attempted to capture the impact of the EE training on how teachers were integrating their training knowledge and what support systems influenced the pedagogy. The research‐evaluation design used cohort panels to address questions regarding immediate and long‐term impacts. Inquiry methods were based on survey questionnaires with ordinal and reflective questions. Some of the key findings were: (1) it takes less than a year to integrate the use of scientific protocols into teaching practices, (2) current scientific methodologies appear to support student use of the Internet for research purposes, and (3) both internal and external school support are necessary to ensure protocol integration and Internet use.     

Teachers designing curriculum as professional development: A model for transformational science teaching

We have designed a model for transformational science teaching focused on linking theory and practice through curriculum decision making that has been the framework for professional development sessions for middle-grade science teachers during the past 5 years. Interviews with teachers revealed that their experiences with curriculum development were of significant value in making decisions concerning the design of classroom environments. As teachers reflected on current research about teaching and learning, in collaboration with university scientists and science educators, they were informed by theoretical perspectives which held implications for their practice. Curriculum development became a vehicle for professional development and school reform; however, it was vital that the teachers were in clear communication with their administrators and communities concerning reform issues. Students and teachers from schools implementing the model and from control sites were interviewed to determine the model's influence on instructional practices and student attitude and achievement in science. The five-phase model for transformational science teaching is discussed here, accompanied by teacher comments about tensions experienced at each phase. This discussion is followed by an analysis of teacher and student interview data that reveals teachers' use of instructional strategies and students' attitudes toward science. Results and analysis of student performance on a mandated end-of-grade science test are also included. From this evidence, we recommend a new design for professional development opportunities for teachers that engages them in decision making as they reflect about the connections between theory and practice and the value of continually testing, revising, and reevaluating curriculum and instructional issues.

Beginning and end of the internship: student teachers’ interpersonal profiles and the accuracy of their self-beliefs

An important purpose of internships in teacher preparation programmes is to develop competence through experience. The research questions in the present study concern student teachers’ interpersonal profiles (i.e. patterns of their interpersonal behaviour as perceived by students) and the accuracy of their self-belief regarding the interpersonal relationship with students at the beginning and end of the internship. Participants were student teachers (n=34) of a one-year teacher education programme. There were fewer student teachers with preferable interpersonal profiles at the end of the internship than in the beginning. Self-beliefs at the beginning indicated that the majority of student teachers were underestimating themselves; at the end of the internship most of them were overestimating themselves. About two-thirds had more accurate self-beliefs at the end of the internship than at the beginning. Overestimating oneself seemed negatively related to more accurate self-beliefs at the end of the internship and student teachers with more preferable profiles had more accurate self-beliefs.     

Teachers’ judgment accuracy concerning consistent and inconsistent student profiles

Research on teachers' judgment accuracy has focused on teacher judgments of single student characteristics. We analyzed differences in teachers' judgment accuracy concerning students with consistent and inconsistent cognitive and socio-emotional profiles (i.e., profiles of cognitive abilities, self-concept, motivation, and anxiety). Based on test scores and self-reports of N = 743 students, we identified one inconsistent and two consistent profiles. Judgments of N = 43 teachers yielded only three consistent student profiles, indicating that teachers perceived student profiles to be more consistent than they really were. Contrary to our expectations, teachers' judgments were not more accurate for consistent student profiles.     

The role of the university tutor in school-based work in primary schools in Northern Ireland and the Republic of Ireland

There has been much international debate on the role of the university tutor in the supervision of student teachers during school-based work. This study focuses upon the Irish context, where there has been little research. It involves a comparative study of the views and attitudes of university staff, student teachers and class teachers from the Irish Republic and Northern Ireland. Data collection methods comprised questionnaires to university tutors, class teachers and students (n = 150), focus groups and one-to-one interviews. This project reveals a reservoir of goodwill between tutors, teachers and students, along with a willingness to engage in dialogue and collaboration. Importantly, this study concludes that it is the university tutor who should have the lead role in collaborative models of school-based work partnership, with significant consultation and input from the class teacher and consultation with the student in the evaluation process.     

Effects of teacher professional learning activities on student achievement growth

The authors examined the effects of six types of teacher professional learning activities on student achievement growth over 4 years using statewide longitudinal survey data collected from 467 middle school mathematics teachers in 91 schools merged with 11,192 middle school students' mathematics scores in a standardized assessment in Missouri. The data showed that teacher-centered collaborative activities to learn about mathematics teaching and learning (teacher collaboration and informal communication) seem to be more effective in improving student mathematics achievement than learning activities that do not necessarily involve such teacher-centered collaborative opportunities (professional development programs, university courses, individual learning activities). Teacher-driven research activities through professional conference presentation and participation were also found to be associated with student achievement growth in mathematics. The districts and schools may benefit from investing their professional development funds and resources in facilitating teacher-centered collaborative and research-based learning activities in order to improve student learning.     

Rethinking online discourse: Improving learning through discussions in the online classroom

As colleges continue to expand online offerings, student participation within courses should be assessed to ensure that teachers can best implement effective, responsible lesson plans. This study examined discourse in an online classroom in order to gauge student participation by observing student-to-student and student-to-instructor exchanges within the discussion board. Classroom discourse was analyzed using Stahl’s computer supported collaborative learning methodology. Data was collected to assess development of classroom dialogue through group collaboration, and to determine whether participants were interpreting previous posts and contributing to the development of the discussion topic. This study shows that students within the online classroom were able to construct deeper meanings in classroom dialogues through thoughtful and personal contributions, thereby reaching new understandings through collaborative discussion. This study contends that through insightful planning and guided responses, instructors can manage online classroom discussions to better direct student communications in order to improve collaborative learning and knowledge construction.     

On constructs and the construction of teachers’ professional knowledge in a post-Soviet context

This paper examines the understandings (‘constructs’) of teachers’ professional knowledge and its sources that underpin current practice in initial teacher education in Kazakhstan and in particular the way in which pedagogika contributes to these. Drawing on empirical data collected over four years, the paper illustrates the ways in which professional knowledge and professional preparation of teachers in pre-service institutions are constructed within the Kazakh and Soviet pedagogical traditions, albeit with some reference to international scholars. Teachers’ professional knowledge is formed from pedagogic theory mediated by academic staff in what is seen by many from outside and inside the country who are engaged in educational ‘reform’ in Kazakhstan as a largely didactic style with little or no critical engagement or exploration of the implications for practice. This stands in contrast with two recent professional development programmes: the Collaborative Action Research and Center of Excellence, which are focused on interactive learning and teaching, reflective practice, classroom action research, and teachers’ collaboration as sources for teachers’ professional knowledge. This paper highlights this contrast and begins to explore what happens when these two different approaches to the construction of teachers’ professional knowledge encounter each other.     

Contrived collegiality versus genuine collegiality: demystifying professional learning communities in Chinese schools

Drawing on data from a larger study on Professional Learning Communities (PLCs) and School Leadership in China, this article investigates the practices of teacher collaboration and PLCs in two urban, high-performing secondary schools in Northeast China. Qualitative data were collected from observations, documents and in-depth semi-structured interviews with 20 participants. The findings reveal that intentionally arranged organisational structures support teacher professional learning and collective inquiry. Collaborative teams in two schools are characterised by genuine collegiality, promoting disciplined collaboration and shared responsibility, which is different from contrived collegiality imposed on teachers. Professional learning is ongoing, supported and fully integrated into the culture and operation of the school system. Emotional bonds, trust and an inclusive school culture contribute to genuine collegiality. These learning communities establish a system of focused collaboration, peer mentoring and collective responsibility, which leads to improved teaching and student learning.     

Classroom practices of cooperating teachers and their relationship to collaboration quality and time: perceptions of student teachers

This study examined the complexities of the collaborative relationship between student teachers and cooperating teachers in secondary mathematics from the perspectives of the student teachers. Four cohorts of student teachers (N = 170) in secondary mathematics were surveyed using a questionnaire that measured their perceptions of two dimensions of their student teaching experience: collaboration with their cooperating teachers and the classroom practices of their cooperating teachers. Although analysis of the responses revealed that student teachers were generally satisfied with the amount and quality of the collaboration, two important results were revealed. First, about half of the respondents reported spending less than an hour collaborating weekly with their cooperating teacher in various contexts. Second, certain classroom practices of the cooperating teachers were found to be significantly associated with whether they spent more or less than an hour collaborating with their student teachers, and were significantly correlated in most cases. This explicit linkage suggests that the classroom practices of cooperating teachers may extend to the mentoring approach they take when working with student teachers. Suggestions for teacher education programs and cooperating teacher support are shared.     

Education-Industry Collaboration in Europe

Mediated interaction with the world of work, especially business and industry, is increasingly seen, world-wide, as a valuable component of science and technology education. A recent WOCATE meeting held in Germany for senior educators, administrators, and industrial representatives aimed to stimulate international partnerships that explore the unity of academic studies and practical work and prompts a review of some European approaches to collaboration between science education and industry. In particular, the British experience favors a variety of agencies, including sponsorship from the professional associations of teachers, scientists, and engineers; substantial participation from industrial companies, individually and through associations; and much essentially voluntary activity by enthusiastic industrial scientists and teachers at all levels.
