This paper reports our experiences in working with precollege and undergraduate American Indian students. In 1990, we began a fourth-grade after-school science program for 30 American Indian students. At the present time the program, called Scientific Knowledge for Indian Learning and Leadership (SKILL), involves over 200 American Indian 4th-9th grade students in weekly science/mathematics activities, quarterly Saturday seminars, and summer science camps. We have collected data to try to determine factors that help to improve student attitudes towards mathematics and science. Conclusions are drawn from these analyses and from our own subjective observations. The development of American Indian involvement in undergraduate science and engineering education on our campus has been aided by the establishment of an American Indian Science and Engineering Society (AISES) chapter and also by the promotion of collaborative learning. A comparison of our observations in the framework of other more well-established programs is given. Changes that have occurred as a result of both precollege and college activities are described and discussed. It appears that each of these activities has had beneficial influences on the other. We also report problems and concerns as well as recommendations to other groups or institutions who may be embarking on similar endeavors.  相似文献

Throughout the United States, various summer science programs for precollege students are conducted with an aim toward increasing the involvement of young people in science. Most of these programs are perceived as successful by teachers and scientists because they involve students in hands-on science activities, improve their scientific skills and confidence, and allow them the opportunity to use science to answer questions and solve problems. The work described here involves a detailed assessment of a summer National Science Foundation (NSF) Young Scholars Program, which was carried out over 2 summers. Student participants were entering 9th and 10th grade. The data used for this assessment included journals kept by teaching assistants, questionnaires administered to the participants and parents, and interviews with the participants. Analysis revealed that students perceived program success differently from teachers and program organizers. Their perception of the success of a program is directly related to whether or not their individual research project met its goals, regardless of other project activities. Designing projects that have a high likelihood of success from this perspective can be complex, but this work identified six variables that must be incorporated appropriately into the design of a project to ensure its success: (1) extent of project structure and who structures the project, faculty or student; (2) project relevance; (3) project flexibility; (4) project background research; (5) tangible results; and (6) project introduction.  相似文献

The Biology Workbench (BW) is a web‐based tool enabling scientists to search a wide array of protein and nucleic acid sequence databases with integrated access to a variety of analysis and modeling tools. The present study examined the development of this scientific tool and its consequent adoption into the context of high school science teaching in the form of the Biology Student Workbench (BSW). Participants included scientists, programmers, science educators, and science teachers who played key roles along the pathway of the design and development of BW, and/or the adaptation and implementation of BSW in high school science classrooms. Participants also included four teachers who, with their students, continue to use BSW. Data sources included interviews, classroom observations, and relevant artifacts. Contrary to what often is advocated as a major benefit accruing from the integration of authentic scientific tools into precollege science teaching, classroom enactments of BSW lacked elements of inquiry and were teacher‐centered with prescribed convergent activities. Students mostly were preoccupied with following instructions and a focus on science content. The desired and actual realizations of BSW fell on two extremes that reflected the disparity between scientists' and educators' views on science, inquiry science teaching, and the related roles of technological tools. Research on large‐scale adoptions of technological tools into precollege science classrooms needs to expand beyond its current focus on teacher knowledge, skills, beliefs, and practices to examine the role of the scientists, researchers, and teacher educators who often are involved in such adoptions. © 2010 Wiley Periodicals, Inc.

Science locus of control (SciLOC) orientation is examined as a predictor of attitudes toward science teaching among 104 preservice elementary school teachers. SciLOC orientation refers to beliefs people hold regarding their personal efficacy, or ability to influence the outcome of events, in situations where decisions or actions require either the application of scientific knowledge or the use of reasoning skills associated with scientific thinking. A causal model that links such beliefs to attitudes toward science teaching was formulated and tested in this study. Multiple regression analysis demonstrates that 46% of the variance in attitudes toward science teaching expressed by subjects in the sample studied can be explained by SciLOC orientation. Path analysis of the proposed causal model accounts for 57% of the variance in expressed attitudes and 11% of the variance in SciLOC orientation. These results are interpreted as evidence that SciLOC orientation is a major contributor to attitudes expressed toward science teaching among preservice elementary teachers, with the major contributors to SciLOC orientation remaining to be identified. A troublesome relationship between expressed attitudes and academic performance in college science is also noted.  相似文献

Several studies have shown that high school science teachers base their teaching on what professors of college freshman science expect, and that, in some instances, advanced high school courses are needlessly similar to college freshman courses. In order to gain insight of college science professors' expectations and perceptions on selected goals and outcomes of science education, a survey instrument was developed and mailed to 123 heads/coordinators of freshman chemistry in U.S. state and land grant colleges and universities that offer a graduate degree program in chemistry. The results demonstrated that although the coordinators were positive about many science education goals and outcomes they did not value aspects related to societal issues, and no differences among them existed when the results were analyzed according to demographic subgroups such as age and teaching experience. They perceived high school graduates as possessing inadequate skills and perceived measures to improve precollege science education requiring collaboration of precollege and college faculty positively. The implications for science education were that college chemistry professors place values different from those of science educators on some pertinent goals and outcomes of science teaching, a situation that is not helpful to reforming precollege science education.  相似文献

Summary Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science. This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school science teachers to utilize their university science training they must search for ways to adapt their college experiences into appropriate middle school learning experience. The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching hands-on science. The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training as a basis for teaching middle school science.  相似文献

These studies examined attitude toward teaching science (ATTS) using an adaptation of the Bratt Attitude Test (M-BAT); anxiety about teaching science (ANX-TS), as measured by the State-Trait Anxiety Inventory (STAI A-State); and selected demographic variables in preservice elementary teachers for the 1977–1978 and 1978–1979 academic years and a follow-up of those students who completed their student teaching in May 1979. The M-BAT and STAI were administered in September at the beginning of Science 6 (earth science and biology course), in December on the next to last day of Science 6, in May on the next to the last day of Science 5 (physical science), and in May 1979 after student teaching. In the two academic years, both ATTS and ANX-TS became more positive during the sequence Science 6-5. Both changes in ATTS and ANX-TS continued to change in a positive direction after completion of Science 6-5, after student teaching. There were differences in the times that the greatest changes in ATTS and ANX-TS occurred. In both studies, the greatest change in ATTS took place between September and December, during Science 6. The greatest change in ANX-TS, however, took place during Science 5 between December and May in the 1977–1978 study. In the 1978–1979 study, the greatest changes in ANX-TS occurred in Science 6, between September and December. The delayed reduction of ANX-TS in the 1977–1978 study may be explained by differences in teaching patterns. In 1977–1978, two teachers taught only their academic specialty, biology or earth science, to students who switched teachers midsemester. In 1978–1979, the same two instructors taught both biology and earth science to the same students. Correlation coefficients for successive and corresponding administrations of both the M-BAT and STAI suggest these variables are related. Students with more positive ATTS tended to have reduced ANX-TS. Neither the number of high school or college science and math courses completed nor the level of enjoyment of these courses appears to be related to ATTS or ANX-TS for the initial administration of the M-BAT and STAI. Closer examination of data, however, indicates that students with negative ATTS and high ANX-TS were fairly evenly divided in their enjoyment of mathematics, while students with positive ATTS and low ANX-TS enjoyed math in a 3:1 like/dislike ratio. The relationship between both ATTS and ANX-TS and achievement is reasonalbly consistent for Science 6. In Science 5, however, the relationship between ATTS and achievement is inconsistent and there is no indication of a relationship between achievement and ANX-TS.  相似文献

Science education models for secondary and college students as well as K‐12 teachers have been dominated by classroom‐based approaches. Recently, research apprenticeships wherein learners worked with practicing scientists on authentic scientific research have become increasingly popular. The purpose of this critical review of the literature was to review and synthesize empirical studies that have explored learning outcomes associated with research apprenticeships for science learners. We reviewed 53 studies of scientific research apprenticeship experiences for secondary students, undergraduates and teachers, both pre‐service and in‐service. The review explored various learning outcomes associated with participation in research apprenticeships. These outcomes included effects of apprenticeship experiences on participant career aspirations, ideas about the nature of science (NOS), understandings of scientific content, confidence for doing science and intellectual development. The extant literature supported many of the presumed positive associations between apprenticeship experiences and desired learning outcomes, but findings related to some themes (e.g., NOS understandings) supported conflicting conclusions. Implications included importance of the length of the apprenticeship, need to explicitly place attention on desired outcomes, and engagement of participants. © 2009 Wiley Periodicals, Inc.

Despite decades of precollege science education programs, African Americans, Latinos, and Native Americans remain critically underrepresented in science and health professions. This report describes college and career outcomes among graduates of the Stanford Medical Youth Science Program (SMYSP), a 5-week summer residential program for low-income high school students among whom 97% have been followed for up to 21 years. Approximately 24 students are selected annually, with participation limited to low-income students who have faced substantial personal hardships. Undergraduate and medical students provide key program leadership and training. The curriculum is based on science inquiry education and includes hospital internships, anatomy practicums, research projects, faculty lectures, college admissions/standardized test preparation, and long-term college and career guidance. A total of 476 high school students participated between 1988 and 2008, with 61% from underrepresented ethnic minority groups. Overall, 78% of African American, 81% of Latino, and 82% of Native American participants have earned a 4-year college degree (among those admitted to college, and excluding those currently attending college). In contrast, among 25–34-year old California adults, 16% of African Americans, 8% of Latinos, and 10% of Native Americans earn a 4-year college degree. Among SMYSP’s 4-year college graduates, 47% are attending or have completed medical or graduate school, and 43% are working as or training to become health professionals. SMYSP offers a model that expands inquiry-based science education beyond the classroom, and recognizes the role of universities as “high school interventionists” to help diversify health professions.  相似文献

In her article “A Possible ‘Orality’ for Science?” (Interchange, Vol. 23, No. 3, pp. 227–244), Rampal argues that science can be made more relevant to students if its language is reformed and replaced by one that contains elements drawn from oral cultures. There is some point to this policy proposal, but it fails to note that the dispassionate and impersonal prose of science has its own function in the on-going practice of science. The real task for the teacher should not be reforming the language of science but rather using oral culture to lead students in the excitement of scientific theories and the joys of scientific research, bringing them in the end to a mastery of the prose style that the scientific community has found serves well its goal of increasing our knowledge of laws of nature.  相似文献

To examine how school characteristics are tied to science and engineering views and aspirations of students who are underrepresented in science and engineering fields, this mixed‐methods study explores relationships between aspects of students' science identities, and the representation of women among high school science teachers. Quantitative analyses tested the hypothesis that percent female faculty would have a positive effect on girls' science interests, and perceptions in particular, given the potentially greater availability of women role models. Findings indicate that percent female science faculty does not have an effect on a range of science measures for both male and female students, including the ways in which they understand scientific practice, their science self‐concept, and their interest in science‐related college majors. As qualitative data demonstrate, this could reflect practical constraints at schools where female faculty are concentrated and narrow perceptions of science teachers and “real” science. © 2007 Wiley Periodicals, Inc.

The purpose of this study was to investigate the relationship of subject matter knowledge in science and the patterns of entering, leaving, and remaining in the teaching profession among college graduates trained to be science teachers. To do this, National Teachers Examination (NTE) Biology and General Science test scores served as the proxy for science subject matter knowledge for a sample of 83 individuals initially certified to teach science in North Carolina during a 4-year period of time. The career patterns of these individuals as science teachers were documented and their work status was identified as nonrecruits, defectors, or career teachers. Using maximum likelihood logistical regression (MLOGIT) analysis, the relationship between career status (the dependent variable) and knowledge of science, race, gender, and the race and status (public or private) of the college from which they graduated was investigated. Of the 83 individuals in the analysis, 30 (36.1%) were identified as nonrecruits, 31 (37.3%) as defectors, and 22 (26.5%) as career teachers. Science subject matter knowledge was found to have a significant (p = .01) effect on the likelihood of being a nonrecruit versus a career teacher. The magnitude of this effect was also important, with the likelihood of being a nonrecruit increasing 120% for every 100-point increase in score on the NTE Biology and General Science tests. Science subject matter knowledge also had a significant effect (p = .05) on the likelihood of being a defector versus a career teacher, with the likelihood increasing 80% for every 100-point increase in NTE Biology and General Science scores. No other significant relationships were found.  相似文献

Reading the interesting article Discerning selective traditions in science education by Per Sund, which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.  相似文献

Reading is fundamental to science and not an adjunct to its practice. In other words, understanding the meaning of the various forms of written discourse employed in the creation, discussion, and communication of scientific knowledge is inherent to how science works. The language used in science, however, sets up a barrier, that in order to be overcome requires all students to have a clear understanding of the features of the multimodal informational texts employed in science and the strategies they can use to decode the scientific concepts communicated in informational texts. We argue that all teachers of science must develop a functional understanding of reading comprehension as part of their professional knowledge and skill. After describing our rationale for including knowledge about reading as a professional knowledge base every teacher of science should have, we outline the knowledge about language teachers must develop, the knowledge about the challenges that reading comprehension of science texts poses for students, and the knowledge about instructional strategies science teachers should know to support their students’ reading comprehension of science texts. Implications regarding the essential role that knowledge about reading should play in the preparation of science teachers are also discussed here.  相似文献

Science textbooks are dominant influences behind most secondary science instruction but little is known about teachers' approach to science reading. The purpose of this naturalistic study was to develop and validate a Science and Reading Questionnaire to assess secondary science teachers' attitudes toward science reading and their beliefs or informed opinions about science reading. A survey of 428 British Columbia secondary science teachers was conducted and 215 science teachers responded. Results on a 12-item Likert attitude scale indicated that teachers place high value on reading as an important strategy to promote learning in science and that they generally accept responsibility for teaching content reading skills to science students. Results on a 13-item Likert belief scale indicated that science teachers generally reject the text-driven model of reading, but they usually do not have well-formulated alternative models to guide their teaching practices. Teachers have intuitive beliefs about science reading that partially agree with many research findings, but their beliefs are fragmented and particularly sketchy in regard to the cognitive and metacognitive skills required by readers to learn from science texts. The findings for attitude, belief, and total scales were substantiated by further questions in the Science and Reading Questionnaire regarding classroom practice and by individual interviews and classroom observations of a 15-teacher subsample of the questionnaire respondents.  相似文献

This study assessed the effectiveness of one science teacher education program designed to be a model program. The study provided evidence that preservice science teacher education can have a very positive effect on the development of preservice science teachers into effective practicing teachers. Thirty program graduates completed a pilot version of the 1985 National Survey of Science and Mathematics Education providing information on course objectives, teaching strategies, equipment use, time allocation, and textbook use. The responses of program graduates were compared to the responses of a select national sample of teachers. All teachers in the comparison group were from programs in the Search for Excellence in Science Education, Presidential Award winners, recognized as outstanding state science teachers, employed as department chairs, or actively involved in the development of science curriculum. Analysis of the responses indicated that both program graduates and comparison group teachers had similar course objectives and teaching strategies, used materials and equipment a similar amount of time, and allocated class time in similar ways. In another component of the study, students of 37 program graduates completed a questionnaire that assessed their attitudes toward science teachers, science classes, and the study of science. Analysis of attitudinal data from their 2871 students indicated that students of program graduates generally had positive attitudes. For instance, 89% of the students perceived their science teacher as asking questions and 80% perceived their science teacher as letting them ask questions. In general, the data are in stark contrast to the images obtained from National Assessment efforts.  相似文献

Science textbooks are frequently used to convey a great deal of the information that students receive in science courses. They influence how science teachers organize the curriculum and how students perceive the scientific enterprise. An overreliance on these teaching aids often results in an overemphasis on terminology and vocabulary, and presents a false impression of the nature of science. As a result of their importance, a method was developed to assess the curricular emphasis in science textbooks. The procedure is explained in a 25-page manual to train researchers to determine the relative emphasis that has been given to (a) science as a body of knowledge, (b) science as a way of investigating, (c) science as a way of thinking, and (d) the interaction among science, technology, and society. Textbooks in the areas of life science, earth science, physical science, biology, and chemistry were used in the analyses. Interrater agreements of at least 80% and kappas of at least 0.73 were achieved in the content analyses among two experienced researchers and one science teacher who were given the training manual to learn the assessment procedure.  相似文献

Many biomedical research universities have established outreach programs for precollege students and teachers and partnerships with local school districts to help meet the challenges of science education reform. Science outreach programs held in university research facilities can make science more exciting and innovative for high school students and can offer them much more insight into the nature of science and laboratory research than is available in most high school science courses. This paper describes a long-term follow-up study of high school students enrolled in the Summer Science Academy program at the University of Rochester to investigate the program's impact on students' perceived abilities in higher level science courses, on participation in extracurricular science programs, as well as the program's impact on student interest in pursuing a career in science. Students' exposure during SSA to advanced laboratory techniques and their participation in authentic science investigations provided them with a very positive hands-on experience. Students who attended the program indicated that it provided a positive influence on their performance in advanced science courses, as well as their decision to participate in other science programs and their desire to pursue a career in science.  相似文献
