Advanced educational technology promises to improve science teaching and learning. To achieve the posited outcomes, however, teachers must have access to, know how to, have the skills to, and want to use the proposed advanced educational technologies in their teaching. In response, for the past eight years with support from the National Science Foundation, BSCS has conductedENLIST Micros — a teacher development to help science teachers improve their use of microcomputers.ENLIST Micros has three phases — Phase one (1984–1986): BSCS designed, tested, and producedENLIST Micros (Ellis and Kuerbis, 1987, 1989) teacher development materials (text, video, and tutorial software) for helping science teachers improve their use of educational technology. Phase two (1986–1989): BSCS designed, developed, tested, and disseminated a staff development model for helping science teachers integrate educational technology into instruction. Phase three (1989–1992): BSCS established Teacher Development Centers to implement theENLIST Micros teacher development materials and staff development model with science teachers throughout the United States.ENLIST Micros has served more than 1500 science teachers in 15 states. Teachers who have participated in the program have improved their knowledge, attitude, and self-efficacy about computer usage and have improved their use of microcomputers in their science courses. Furthermore, as part of the project, BSCS has described the implementation process and has developed recommendations to support improvements in the use of educational technology in science programs. 相似文献

A variety of handheld applications and curricular materials have been developed to support inquiry science learning in recent years, but there are few handheld-supported assessment activities available to teachers. In Project WHIRL, researchers from SRI International worked in partnership with teachers from Beaufort County School District (SC) to develop a suite of handheld software applications that could be used to support classroom assessment in upper elementary and middle school science classrooms. In this paper, we will analyze results from a field trial conducted in 2003–2004 with 18 teachers in the district, focusing on how teachers’ enactment of handheld-supported assessment activities altered the frequency and quality of their assessment practices.This material is based in part on work supported by the National Science Foundation under Grant Number REC-0126197.

Does MSP Participation Increase the Supply of Math Teachers? Developing and Testing an Analytic Model 总被引：1，自引：1，他引：0
An important feature of the Math and Science Partnership (MSP) Program of the National Science Foundation is to increase K-12 student achievement in math and science by increasing the quality, quantity, and diversity of the nation's K-12 math and science teachers. Because the underlying supply of math and science teachers is never directly observed, the central premise of this article is that an examination of the extent to which the MSP Program might impact the quantity and quality of math and science teachers requires careful thought and modeling. With that starting point, this study first develops a model that supports a premise that shifts in underlying supply can be inferred from shifts in the percentage of certified math teachers employed when (a) salaries are constrained to be below market clearing salaries and (b) uncertified or “out-of-field” certified teachers can compete as substitutes for certified math teachers. The study then tests the plausibility of the model using data from Texas and in so doing provides preliminary estimates of the extent to which a school or school district's MSP participation affected the supply of certified math teaches available to that school or district. The results, although inconclusive on the question of the labor supply effects of MSP participation by a school or school district, do suggest the reasonableness of the model for future work when more appropriate data will be available. 相似文献

Conclusion The most important finding from this study is that if one adheres to the guidelines from the literature on staff development
and educational change, teachers can and will change their teaching behaviors. It is very easy, however, to underestimate
the time and resources required to implement change in schools. Even a seemingly simple change such as increasing use of educational
computing, which teachers can implement in their individual classrooms without an overhaul of schools, is immensely complex
and difficult. Helping teachers and schools change requires a systematic effort, with intensive on-going support over a period
of three or more years. Science educators, school leaders, and the public must learn that school improvement is not an event
but a continual process of renewal and refinement.
This study demonstrates the importance of allocating resources to staff development and implementation along with those for
curriculum development. Fortunately, the National Science Foundation has recognized the importance of implementation in school
improvement by requiring that implementation be an integral part of all curriculum development projects it funds. As Hall
(1986) said, “It is not enough to build pretty boxes; what is important is to get the boxes used.”

Funded by innovative programs at the National Science Foundation and the Howard Hughes Medical Institute, University of Richmond faculty in biology, chemistry, mathematics, physics, and computer science teamed up to offer first- and second-year students the opportunity to contribute to vibrant, interdisciplinary research projects. The result was not only good science but also good science that motivated and informed course development. Here, we describe four recent undergraduate research projects involving students and faculty in biology, physics, mathematics, and computer science and how each contributed in significant ways to the conception and implementation of our new Integrated Quantitative Science course, a course for first-year students that integrates the material in the first course of the major in each of biology, chemistry, mathematics, computer science, and physics. 相似文献

Undergraduate college “science partners” provided content knowledge and a supportive atmosphere for K–5 teachers in a university–school professional development partnership program in science instruction. The Elementary Science Education Partners program, a Local Systemic Change initiative supported by the National Science Foundation, was composed of four major elements: 1) a cadre of mentor teachers trained to provide district-wide teacher professional development; 2) a recruitment and training effort to place college students in classrooms as science partners in semester-long partnerships with teachers; 3) a teacher empowerment effort termed “participatory reform”; and 4) an inquiry-based curriculum with a kit distribution and refurbishment center. The main goals of the program were to provide college science students with an intensive teaching experience and to enhance teachers'' skills in inquiry-based science instruction. Here, we describe some of the program''s successes and challenges, focusing primarily on the impact on the classroom teachers and their science partners. Qualitative analyses of data collected from participants indicate that 1) teachers expressed greater self-confidence about teaching science than before the program and they spent more class time on the subject; and 2) the college students modified deficit-model negative assumptions about the children''s science learning abilities to express more mature, positive views. 相似文献

Teaching and Learning Physics in a 1:1 Laptop School 总被引：1，自引：1，他引：0
1:1 laptop programs, in which every student is provided with a personal computer to use during the school year, permit increased
and routine use of powerful, user-friendly computer-based tools. Growing numbers of 1:1 programs are reshaping the roles of
teachers and learners in science classrooms. At the Denver School of Science and Technology, a public charter high school
where a large percentage of students come from low-income families, 1:1 laptops are used often by teachers and students. This
article describes the school’s use of laptops, the Internet, and related digital tools, especially for teaching and learning
physics. The data are from teacher and student surveys, interviews, classroom observations, and document analyses. Physics
students and teachers use an interactive digital textbook; Internet-based simulations (some developed by a Nobel Prize winner);
word processors; digital drop boxes; email; formative electronic assessments; computer-based and stand-alone graphing calculators;
probes and associated software; and digital video cameras to explore hypotheses, collaborate, engage in scientific inquiry,
and to identify strengths and weaknesses of students’ understanding of physics. Technology provides students at DSST with
high-quality tools to explore scientific concepts and the experiences of teachers and students illustrate effective uses of
digital technology for high school physics. 相似文献

This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment.
The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in
scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies
to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science.
The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner
tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed.

The Southwest Regional Laboratory, through major funding from the National Science Foundation (ESI-9450235), has developed a series of eight instructional modules for use in common secondary school physical science that address three central goals of U.S. science literacy education: (1) to motivate students who have previously shown little interest in science; (2) to accomplish deep change in students' internalized conceptions of the structure and workings of the physical world; and (3) to build greater understanding, in both teachers and students, of the process and culture of scientific activity.Beginning with a discussion of the conceptual scaffolding that undergirds the project's pedagogical approach, the paper presents an overview of MindWorks' goals, the materials that have been developed to achieve these goals, and the progress of the pilot implementation and project evaluation. 相似文献

Involving people outside of a science course can foster learning for students enrolled in the course. Assignments involving friends and family provided such opportunities in an undergraduate physics course for prospective teachers. These assignments included reflecting upon prior experiences, interviewing friends and family members, engaging them in exploring physical phenomena, and teaching them with relevant websites. The six strands of science learning articulated in Learning Science in Informal Environments (National Research Council in Learning science in informal environments: People, places, and pursuits. National Academies Press, Washington, DC, 2009) provided a framework for analyzing the prospective teachers’ responses. Through such assignments, the instructor created opportunities for the prospective teachers to use and build upon knowledge learned in class as well as to gain confidence and experience in facilitating the learning of others. 相似文献

Summary The major purpose of the SCI-LINK Projects was to explore ways of linking research scientists and school science teachers.
Not only did the project provide these teachers with a better understanding of scientific environmental research and recent
findings, but it allowed them to develop activities and other instructional materials they could use in their classrooms.
Leadership skills also were developed as evidenced by the Master Teachers that evolved and the many professional activities
in which they have been engaged since the first institutes.
Many things were done during the course of the project in order to make the process more efficient. These include assistance
to scientists in making their presentations and field trips more effective and helping teachers with their writing and library
skills. Also explored were the nature and format for the activities the teachers developed and how they can best be evaluated
and disseminated.
Positive feedback from teachers and the continued interest of research scientists to participate has led to another project
patterned after the model used in the SCI-LINK Project. This second generation project, GLOBE-NET, also supported by the National
Science Foundation, involves scientists and teachers in the development of instructional materials on global change.
At least some of the efforts to improve science education should include scientists and teachers as partners. The model used
in the SCI-LINK Project provides one way of doing so. 相似文献

Much has been said about what science content students need to learn (e.g., Benchmarks for Science Literacy, National Science Education Standards). Less has been said about what science content teachers need to know to teach the content students are expected to learn.
This study analyzed four standards documents and assessment frameworks to identify core middle school physical science teacher
content knowledge. Analysis across all four documents identified critical middle school physical science content and the relative
weightings of this content. This parsimonious selection of content synthesized from these major sources provides guidelines
researchers, assessment developers, and professional development providers can use in determining how to expend limited time
and other resources. 相似文献

Weight is one of the basic concepts of physics. Its gravitational definition accommodates difficulties for students to understand
the state of weightlessness. The aim of this study is to investigate the effect of materials based on 5E teaching model and
related to weightlessness on science student teachers’ learning. The sample of the study was 9 volunteer student teachers
who were in their first grade in Science Teaching Program in Fatih Faculty of Education, Karadeniz Technical University. Both
qualitative and quantitative data were gathered to find answers to the research questions. Findings revealed that all physics
textbooks reviewed gave gravitational definition of weight. Also the concept of weightlessness hasn’t been covered in high
school and some university textbooks. It was determined that before the implementation student teachers had non-scientific
explanations about weightlessness. The implementation of the 5E teaching model and materials developed are effective on learning
the weightlessness. It is suggested that similar applications can also be used in other physics subjects or in other fields
of science. 相似文献

This longitudinal study of middle school science teachers explored the relationship between effective science instruction,
as defined by the National Science Education Standards (NRC in National science education standards. National Academy Press,
Washington, DC, 1996), and student achievement in science. Eleven teachers participated in a three year study of teacher effectiveness, determined
by the LSC Classroom Observation Protocol (Horizon Research, Inc. in Local Systemic Change Classroom Observation Protocol.
May 1, 2002) and student achievement, which was assessed using the Discovery Inquiry Test in Science. Findings in this study revealed the positive impact that effective science teachers have on student
learning, eliminating achievement gaps between White and Non-White students. Case studies of three teachers, both effective
and ineffective explore the beliefs and experiences that influence teachers to change, or not to change practice. This study
provides justification for teaching science effectively to narrow achievement gaps in science and provides insight to stakeholders
in science education as to how to support teachers in becoming more effective, through addressing existing teacher beliefs
and providing experiences that challenge those beliefs. 相似文献

ABSTRACT: The Institute of Food Technologists (IFT), the IFT Foundation, and Discovery Education partnered to create and distribute food science information to science department and school counselor chairs in all 18000 U.S. high schools in January 2006. Two multimedia "kits" were generated for teachers and counselors, each consisting of DVDs with food science technical or career information, respectively, and a call to action to visit a newly created web microsite. To support and promote the program, IFT initiated a "Food Science Ambassador" program, where IFT member food scientists complete a brief survey indicating their interest in speaking with or visiting teachers, students, and counselors to discuss the field of food science or give a demonstration. IFT, through the career guidance committee, exhibited and conducted workshops at the National Science Teachers Association regional and national conferences, and coordinated a "Train the Trainer" program at the IFT Annual Meeting in Florida for local area science teachers and Food Science Ambassadors. Survey results from kit recipients were overwhelmingly positive, with over 97% of the respondents indicating that they intend to use the materials. The microsite developed for this program received over 18000 unique visits in the first 6 mo, and traffic to the IFT Teacher Resources web page increased. In the first 6 mo of its availability, nearly 250 IFT members have signed up to be Food Science Ambassadors. Long-term metrics for success are in place and continue to be monitored. 相似文献

Inquiry-Events as a Tool for Changing Science Teaching Efficacy Belief of Kindergarten and Elementary School Teachers 总被引：1，自引：1，他引：1
Researchers agree that science education should begin at childhood, due to its contribution to later cognitive skill development. However, in most cases only a small portion of kindergarten and elementary school activities is related to science. Given the tremendous impact teachers have on children and on the success or failure of their curriculum, teachers' efficacy belief toward science teaching (TEBTST) should be of significant concern. It is suggested herein that in order to improve TEBTST, the science curriculum should be developed not only from the perspective of the child's needs, but will explicitly consider the teachers' needs as well. Such an approach is described in this study, and is labeled as the Inquiry Events (IE) teaching method. This method involves relating to an open-ended problem situated in real life, that encourages investigation of a variety of issues—ethical, economic, scientific, etc.—which both kindergarten and elementary school teachers are accustomed to considering. The method encourages teachers to relate to these daily situations by introducing scientific questions, which they would ordinarily ignore or omit. Using the STEBI (Science Teaching Efficacy Beliefs Instrument) questionnaire before and after a 4-day workshop introducing the IE method, it was found that IE improved TEBTST and increased their confidence in teaching science. 相似文献
