This paper describes part of a project called Modeling Across the Curriculum which is a large-scale research study in 15 schools across the United States. The specific data presented and discussed here in this paper is based on BioLogica, a hypermodel, interactive environment for learning genetics, which was implemented in multiple classes in eight high schools. BioLogica activities, data logging, and assessments were refined across this series of implementations. All students took a genetics content knowledge pre- and posttests. Traces of students' actions and responses to computer-based tasks were electronically collected (via a log file function) and systematically analyzed. An intensive 3-day field test involving 24 middle school students served to refine methods and create narrative profiles of students' learning experiences, outcomes, and interactions with BioLogica. We report on one high school implementation and the field test as self-contained studies to document the changes and the outcomes at different phases of development. A discussion of design changes concludes this paper. 相似文献

Psychologists and psychology students (n = 138) were provided an artificial-intelligence program that simulated a date rape client's responses to typed questions. Participants were asked to conduct a clinical interview by typing in their questions. Clinical experience was unrelated to participants' levels of confidence, perceived expertise, and efficiency in generating or analyzing questions. Both experience and academic level of training, however, affected participant's mode of questioning. 相似文献

Influences of the Normative Environment of Peer Groups on Community College Students' Perceptions of Growth and Development 总被引：1，自引：0，他引：1
Grounded in Weidman's (1989a) socialization model and Pace's (1979b) theoretical conception of quality of effort, this study examines the effects of peer groups on community college students perceptions of general educational gains. Peer groups were defined as the aggregate student body within an institution. The sample consisted of a national sample of community college students who had responded to the Community College Student Experiences Questionnaire. Given the nested structure of the data, hierarchical linear modeling was used to examine institutional- and student-level effects. Dominant influences on students' perceived gains were from the quality of effort exerted by students. Aggregates of individual-level measures were used as indicators of the peer environment and had little impact on individual-level estimates. 相似文献

This article provides an opportunity to extend the discussion about teacher communities as part of complex school reform models, specifically centered on those communities whose membership is drawn on a semi-voluntary basis. Through a sixteen-month long ethnography, I document the activities of an urban teacher professional community (TPC) at a high school located in a large city in the Northeast, serving a majority of linguistically and culturally diverse students. Guided by Sharp and Greens definition of teacher ideologies, the study focuses on how TPC members negotiated curriculum, teacher learning, and student discipline, carrying ideologies that impacted the outcomes of the communitys work, originally intended to increase teacher collaboration and foster quality teaching.Jorgelina Abbate-Vaughn is an Assistant Professor in the Department of Curriculum and Instruction at the University of Massachusetts-Boston. Her research interests center on the possibilities and challenges that urban schools pose, on school reform approaches, on teacher preparation, and on e.ective educational approaches for low-income, culturally and linguistically diverse (LCLD) students.

This article is concerned with reactions to systemic change as Australian higher education was transformed from a binary system (of Colleges of Advanced Education, CAEs, and universities) to a unitary system of universities. It, in turn, was part of the much more influential role which government now played in higher education affairs. The counter images relate to the expressive positions of those who were either opposed to, or had deep reservations about, this transformation.The counter imagists offer a perspective, worthy of study, of the impact of profound change upon higher education. Further, since reform, in Australia, had similar causes to that in other OECD countries (the impact of mass higher education, economic rationalism, an official view of higher education as an instrument of national economic revival), its manifestations in one national setting, and reactions to it, are likely to be of international interest.More specifically, the counter imagists were concerned about the loss of differentiation in the new unitary system: To them, it would affect total higher education delivery by making is less specialised, introduce an artificial egalitarianism into higher education affairs and have an adverse bearing upon the effectiveness of traditional universities, particularly their research contribution. There was also anxiety about direct role played by government in institutional funding and related management decisions, as well as the setting of a wider higher education agenda, through measures such as national priorities and social equity goals.The counter imagists, then, are those who took a prominent, but conservative role, in the debates during the half decade of great change in Australian higher education, 1988–1993, and were vigorous in their defence of the autonomy of universities. The article is introduced by placing systemic change in its historic setting, including the rise and fall of the binary system and perceptions of the university legacy. 相似文献

Galileo's contemporaries as well as today's students have difficulty understanding relative motion. We hypothesize that the construction of visual models, resolution of these visual models with numeric models, and, in many cases, rejection of commitments such as the belief in one true velocity, are necessary for students to form integrated mental models of relative motion events. To investigate students' relative motion problem solving, high school science students were videotaped in classroom and laboratory settings as they performed collaborative predict-observe-explain activities with relative motion computer simulations. Half of the students interacted with simulations that provided animated feedback; the other half received numeric feedback. Learning, as measured by a diagnostic test, occurred following both conditions. There is evidence that many numeric condition students used faulty mechanical algorithms to solve problems, while many animation condition students used mental imagery to solve problems. In this paper, interactions in which student involvement was visual model based will be contrasted with interactions in which involvement was algorithm based. Implications for pedagogy and educational uses of computer simulations will be discussed. 相似文献

According to the ethos of the nineteenth century common school, all students are assigned the same tasks, and in all the same powers developed. Twentieth century innovations such as ability grouping are foreign to the common school's egalitarian ideal. Such innovations may reinforce connections between students' ascribed background characteristics and school achievement. Proponents of the common school sought to sever these connections. Coleman, Hoffer, and Kilgore, inHigh School Achievement (1982), argue that private schools are more in keeping with the common school tradition than public schools. In their view, private schools offer greater meritocratic justice than public schools; this is due to the fact that private schools minimize the impact of students' background characteristics, such as race and family income, on achievement. Our findings, however, are inconsistent with those of Coleman et al. We use a data set provided by the Educational Testing Service in which public and private subgroups are approximately equal with respect to measured background factors, and we employ a more adequate complement of independent variables, along with outcome measures which appear to be more curriculum sensitive than those employed by Coleman et al. Our regression results indicate that private secondary schools are no more effective than public schools at severing the connections between background characteristics and measured achievement in English, math, and American history. 相似文献

The purpose of this study was to investigate the extent to which Lebanese Baccalaureate II students' (Freshmen in american colleges) perceptions of their academic abilities match their actual achievements in both school and government examinations. A population sample of 2999 students were selected from a representative school sample (n = 122) throughout Lebanon. Students' demographic data, occupational choices and perceptions of their achievement were collected by a three-part questionnaire. Their cumulative grade averages in school and in government examinations were standardized and used to assess their career maturity. Findings indicated that most students wanted to become engineers or physicians while their actual achievement scores in school was average and in the government examination below average. Most correlational values between perceptions and actual achievement scores were either negative or insignificant. Students were found to make immature career decisions mainly because of the lack of any formal guidance programs in schools. 相似文献

This study examined gender differences in students' scientific literacy as measured by OECD-PISA. In particular, we focused on the 2437 students from 140 Hong Kong schools. Hong Kong boys' and girls' science scores did not differ overall. However, boys scored higher than girls at the higher percentiles (75th and above). Moreover, specific test components showed gender differences. Boys tended to score higher on tests with more earth and physical science items, understanding of scientific knowledge items, and closed items. Meanwhile, girls tended to score higher on recognizing questions and identifying evidence items. These results suggest that a science test assessing diverse content and literacy skills in a variety of response formats provides both a more comprehensive picture of students' capabilities and a more likely gender-equitable assessment. 相似文献

The impact of scienceware and foundations on students' attitudes towards science and science classes
Steven J. Stratford Elizabeth A. Finkel 《Journal of Science Education and Technology》1996,5(1):59-67
In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about using information, drawing conclusions, and thinking about problems, implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems. 相似文献

This research study focused on pupil-teacher interactions in kindergarten classrooms in Hong Kong. Classroom observations of the morning or afternoon sessions of nine kindergarten teachers from three schools were carried out. Teachers, in general, exhibited considerable warmth towards their pupils. Teaching consisted largely of intensive closed questioning and giving instruction that generally involved assigning activities, monitoring students while on task or providing corrective feedback in response to students' errors. When directing discussion, teachers sought to ensure that students offered the required answers. Emphasis was placed on tasks and basic skill activities rather than on helping children to develop learning strategies. It is argued that, to confront and modify the teachers' personal concerns, cognitive dissonance must be induced as a first step in this process of re-orientation. 相似文献

Using data from about 400 ninth-grade students from six junior high schools in Israel, we have investigated students' perceptions about messages conveyed by counselors while guiding them into high school tracks. In Israel, where curriculum differentiation in high school tracks is relatively rigid, the decision on track placement is critical, and guidance at the point of transition is an institutionalized role of the school counselor. Students reported on the nature of messages they received while meeting individually with the counselor. The findings suggest that while counselors seem to be somewhat hesitant about giving very definitive messages, they still differentiate their messages by academic status and gender: low-achievers and girls, especially high achievers, are being cooled-out to a greater degree than all high-achievers and boys. It was also found that the pattern of cool- out and push-up messages vary between schools. 相似文献

This study examined the possibility that notonly women, but also men, face what Hall and Sandler(1982) call chilling behaviors when theyare students in a major considered nontraditional oratypical for their sex. The population for this studywas all upper-level students (N = 1,992) in accounting,education, engineering, and nursing at a publicuniversity in the mid-South. A random sample of females and males, or a total of 426 junior and seniorfull-time and part-time students in these majors, wasmailed a survey about chilling practices in their major.Analysis of variance was used to clarify the relationships between the independent variablesof students' sex and academic discipline and theinteraction of students' sex and academic discipline andthe dependent variable of perception of practices in their major. The findings indicated that,regardless of their sex, students in these majors didnot perceive practices in their major to bechilling. However, there was a differencein perceptions as a function of major. Both education andnursing students perceived a warmerenvironment in their major than did accounting andengineering students. The pattern was the same for bothfemales and males since there was no interaction of sex andacademic discipline. 相似文献

During the last 25 years efforts in the German educational system on different levels were made to introduce computers in schools. In parallel teacher training and consultation was established. Results from the international IEA-study Computers in education for lower secondary level in 1992, but also for upper secondary level in 1989 show that teachers attitudes to learn something about computer use are positive: The training need and their self-confidence to learn something about computers is relatively high. Support for teachers is mainly given by formal training. But the offers in teacher training are limited concerning the needs of teachers for different subjects. This situation is comparable with other countries in the world as documented in the additional publication of national case studies of the IEA. As a consequence a part of the teachers get their help through self-studies and private preparation of course material. In recent years the use of computers for networking and multimedia applications developed rapidly. The integration of these technologies into the subjects is another field demanding intensive efforts in teacher training. Different programs for the development of this field were established, but still offers for teacher training are insufficient. As a new perspective for educational change in this rapidly growing field a classroom-based teaching and learning approach in a collaborative network is proposed. 相似文献

Building on the research of Vygotsky regarding the role of social interaction and the zone of proximal development (ZPD) in learning and development, this paper explored the relation between students' oral thought processes and written thought processes. It is argued that the practice of writing provides a context for a new learning zone: the zone of proximal practice (ZPP). In this new zone, students independently organize their thinking about mathematical concepts and ideas. An interpretative case study of seven middle grade students is presented to support this contention. The case study describes the strategies and procedures students employed while solving mathematical problems and documents students' oral and written thought processes through interview protocols and writing samples. The position that students' mathematical understanding is further developed through writing as a communicative tool, while taking advantage of mediated social practices, is discussed to make clear the rationale for introducing a new learning zone.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

The inclusion of students with disabilities in the mainstream of general education remains one of the most contested topics in public education today. This qualitative study considered this issue from the perspective of included as well as excluded special education students over an extended period of time. More specifically, it sought to understand how 11 developmentally handicapped students made sense of their experience in a variety of inclusive and segregated classrooms in four urban school settings. It followed these students in two elementary schools and two junior high schools over a period of 6 years. The information from participant observation as well as teacher and student interviews supports inclusive schooling. It suggests that, as the students moved into and out of traditionalist and inclusive classrooms, they presented a changing sense of themselves in relation to ideological beliefs and practices within particular schools and classrooms. Students in inclusive classrooms constructed a sense of themselves that was significantly different (and more positive) from those in either segregated or traditionalist classrooms. 相似文献

A specially developed questionnaire was used: Types of Preferred Examinations (TOPE) to assess examination-type preferences of secondary school students in the Science disciplines according to school type affiliate and gender.Structured interviews were employed to assess both the rationale of students towards these preferences as well as teacher awareness about the preferences – in contrast to their actual examination practice.Our findings suggest that (a) secondary school students prefer written, unlimited time examinations which, according to their perception, stress learning with understanding rather than mechanical rote learning, and in which the use of supporting material (open book exams) is permitted; and (b) secondary school Science teachers are aware of student examination-type preferences, yet they continue to use the traditional written, time-limited – class examination which is definitely not preferred (disliked) by their students.In view of the special emphasis in current science education research on students' development of higher-order cognitive skills (HOCS) and the need for consonance between the new curriculum goals and examination types used, it is proposed that provisions be made to facilitate teachers' compliance with students' examination-type preferences provided the latter are congruent with learning objectives and our educational aspirations. 相似文献

Having high school students prove geometrical propositions became the norm in the United States with the reforms of the 1890's — when geometry was designated as the place for students to learn the art of demonstration. A custom of asking students to produce and write proofs in a two-column format of statements and reasons developed as the teaching profession responded to the demands of reform. I provide a historical account for how proving evolved as a task for students in school geometry, starting from the time when geometry became a high school subject and continuing to the time when proof became the centerpiece of the geometry curriculum. I use the historical account to explain how the two-column proof format brought stability to the course of studies in geometry by making it possible for teachers to claim that they were teaching students how to prove and for students to demonstrate that their work involved proving. I also uncover what the nature of school geometry came to be as a result of the emphasis in students' learning to prove by showing that students' acquisition of a generic notion of proof was made possible at the expense of reducing students' participation in the development of new ideas. I draw connections between that century-old reform and current reform emphases on reasoning and proof. I use observations from history to suggest that as we carve a place for proof in present-day school mathematics we must be leery of isolating issues of proving from issues of knowing.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

Engineers in Greece undergo a heavy schooling investment—five years of university study instead of the usual four. Greece is atypical in that women make up a relatively large portion of the engineering work force. Working women earn substantially less than do men and there is evidence of labor market discrimination. In this paper a recent survey (1987) of employed engineers is used to examine earnings differentials between men and women and to compare the results with an examination of the results of an earlier survey (1977). Results indicate that most of the difference in earnings between male and female engineers in Greece is not accounted for by differences in productive characteristics such as education and experience and, therefore, most of the difference may be due to discrimination. Moreover, the proportion of the earnings differential not explained by productivity has increased over time.This is a revised version of the paper presented at the 1991 Cambridge Social Stratification Research Seminar, Gender, Work and Pay, September 26–27, 1991. The views expressed in this paper are those of the author and should not be attributed to the World Bank. 相似文献
