Over the last decade, remote instruments have become widely used in astronomy. Educational applications are more recent. This paper describes a program to bring radio astronomy into the undergraduate classroom through the use of a remote research-grade radio telescope, the MIT Haystack Observatory 37 m telescope. We examine the effectiveness of such remote access in the classroom. The remote use of the large telescope has opened up a research facility for undergraduate students. The experience has been largely successful with over 150 students from about 20 colleges using the telescope every year. The student experiments have included classroom demonstrations by faculty, and short-term laboratory experiments and long-term research experiments performed by students. Although a visit to the site provided students with a sense of the scale of the antenna, operating on a purely remote basis still gave the students a rewarding research and learning experience. The effectiveness of the remote instrument is judged mainly by the student presentations and papers that have been generated, by the enthusiasm of the faculty to continue using the facility as part of their curricula, and through a survey of students and faculty. 相似文献

Becoming a mature student: How adult appplicants weigh the advantages and disadvantages of higher education 总被引：1，自引：0，他引：1
The data presented in this paper is taken fromthe results of two much larger studies ofmature student decision-making and HigherEducation (HE), which considerprocesses of agency from initial considerationof the possibility of becoming a studentto eventually becoming one. In thispaper, six categories of applicant to HE arediscussed: `Delayed traditional students', `Late starters' who have undergone alife-transforming event e.g. redundancy ordivorce and require `a new start'. `Single parents' `Careerists', who are currently in employment who seek a qualification to make progress in their existing careers, `Escapees' who are currently in employment who want a qualification as a way out of `dead-end' jobs, Finally, the `personal growers', a small number pursuing education for its own sake.These categories of applicants are discussed inlight of the factors that both catalyse andinhibit individuals' decision-making duringapplication to HE. 相似文献

This study took place during the first 2 years of a partnership between three cooperating elementary schools and a college of education. The purpose of the interpretive phenomenological study was to learn from cooperating teachers, student-teachers and college instructors about the transitions that accompanied the change in the culture of schooling they experienced through the newly established partnership, and to attempt to understand their experiences through their explanations of the transitions they identified. On the basis of the data analysis, we identified seven transitions experienced by the participants: From discrete processes to parallel, open processes. From individual work to collaboration. From seeing the other as an object to seeing the other as a critical friend. From leading to responding. From the conception of knowledge as an object to the conception of knowledge as a process. From viewing learning as a linear process to viewing it as a spiral process. From viewing their work environment as a closed system to viewing it as an open system. In this paper, we describe and provide examples of each of these transitions and show how they are interrelated and how each one is both a cause and an effect of the others. These findings increased our knowledge about how the school and college altered each others consciousness. 相似文献

This article examines how home and school factors affect the education of Mong students in the U.S., a group that, by in large, is not faring well academically. The study is based on related research and interviews with teachers, students, and the parents of a group of Mong elementary school students in northern California. The findings reveal that Mong students' negative schooling experiences are exacerbated by the mismatch between the home and school culture, by misconceptions and labeling by parents and teachers, and by issues pertaining to their attempts to assimilate into American society. Therefore, Mong students experience a culture clash at home and at school. Conversely, Mong students are empowered by a culturally relevant curriculum, and a school environment that values their culture, and that utilizes their parents as resources. Hence, they need more support from both parents and teachers. 相似文献

Many students have a deep interest in astronomy, but a limited opportunity to use telescopes to explore the heavens. The MicroObservatory Network of automated telescopes is designed to provide access to classroom teachers who wish their students to conduct projects over the World Wide Web. The intuitive interface makes it easy for even 10-year-olds to take pictures. Telescopes can be remotely pointed and focused: filters, field of view, and exposure times can be changed easily. Images are archived at the website, along with sample challenges and a user bulletin board, all of which encourage collaboration among schools. Wide geographic separation of instruments provides access to distant night skies during local daytime. Since first light in 1995, we have learned much about remote troubleshooting, designing for unattended use, and for acquiring the kinds of images that students desire. This network can be scaled up from its present capability of 240,000 images each year to provide telescope access for all US students with an interest in astronomy.

This research models default development for a large proprietary dataset of private (nonfederally guaranteed) education loans extended to law school students in the early 1990s. Employing the statistical techniques of survival analysis and credit scoring, the study documents a pronounced seasoning effect for such loans and demonstrates the robust predictive power of credit bureau scoring of student borrowers. Other constructs found to be statistically predictive of default include school-of-attendance (or, alternatively, a measure of perceived school reputation), geographic location of attended school, and new attorney unemployment rate within certain regions. Although statistically predictive, these last constructs are of far less substantive importance in assessing credit risk than are the effects of portfolio seasoning and scoring (an ordinal measure of the risk of extending credit to an individual based upon their past credit behavior). The article challenges the prevailing approach to modeling student loan default (one that searches for institutional as well as borrower explanations) and suggests a return to the older, simpler banking paradigm of borrower willingness and borrower ability to repay. 相似文献

This hypermedial project deals with a historical and conceptual approach to physics. The core of the project is a certain number of case studies, namely problems or phenomena recounted together with their different interpretations. All case studies present two levels of investigation: the first level is devoted to high school students, the second level is devoted to university students and high school teachers. Our project is directed at a new and better understanding and appreciation of scientific culture.Our methodology is a historical methodology: teaching physics and the history of physics are fellow-subjects. We are not interested in adding the history of physics to teaching physics, as an optional subject: the history of physics is inside physics.Since textbooks usually give one and only one explanation of each physical phenomenon – the true explanation – we would like, on the contrary, to present the phenomena together with different interpretations that factually occurred in the history of physics. We offer four different approaches to the subject of the case study: A. Phenomena, B. Textbooks, C. History and D. Maps.The basic unit of the hypermedia is the presentation , namely a coherent set of information endowed with a definite and complete meaning. From the media point of view, a presentation consists of pictures and/or animations, key-words and/or key-sentences and a speaker explanation. Each approach consists of a certain number of presentations. 相似文献

Although the economic benefits of collaborative schemes and transfer of courses in distance education are clear, examples of collaboration between distance education institutions are rare. A reason is sought in theorganisational climate or ethos of each institution engaged in distance education, which inhibits joint design and use of courses or the transfer of a course from one institution to another. This theme is examined in relation to distance education in the integrated mode system of Australian and New Zealand universities, six in all. The universities are compared in terms of six features of organisational climate of particular relevance to distance education: physical characteristics, academic organisation, involvement in distance teaching, organisation of distance teaching, components of distance teaching and staff attitudes to distance education. It is concluded that the considerable variation between institutions, with respect to these features, creates difficulties for collaboration. The best prospect for collaborative schemes in distance education therefore may have to lie in the use of national or international agencies to validate courses as part of a national or international higher education programme along the lines of Britain's CNAA. 相似文献

This report describes a study which explores, from the out-of-school student viewpoint, why students are not studying chemistry anymore. In a 2-day stay at a research institution three groups of graduating high school students from different schools, together with their chemistry teacher, were confronted hands-on with molecular modeling in industry and in university. Each of these volunteer students had agreed to write an essay on School Chemistry Vs. Chemistry in Research. These essays were evaluated together by the students, the teacher, and the researcher in a meeting at their school. The opinion of the students show that school chemistry does not convey today's chemistry in research and in industry. At the computer screen the students demonstrated their skill in performing molecular modeling experiments. Moreover, at the computer screen, chemistry was fun and easier to understand. Now we begin to see the solution: our students are also our teachers. 相似文献

The Israeli academic preparatory programs (APPs) challenge the sorting regime of regular education by offering a genuine second chance for higher education to youngsters who have failed to acquire the necessary prerequisites via the mainstream. The study analyzes the success of the APPs to produce changes in their students in light of the failure of a different second-chance framework, the community college, to do so. The analysis of a sample of APP graduates indicates that background characteristics and high school history, powerful sources of differentiation upon admittance to the APPs, lose their discriminating power after graduation. All graduates join any postsecondary educational framework, regardless of their initial disadvantages. The success of the APPs in eliminating initial gaps among the students is assigned mainly to their nonconformity to the selection criteria of regular education. The purpose of this research was to assess whether second-chance educational programs that challenge the sorting criteria of the mainstream succeed in enhancing social equality in education. Outcomes of the challenging second-chance academic preparatory programs in Israel are analyzed in light of the reported failure of community colleges to moderate inequalities in higher education. 相似文献

On the assumption that colleges need a theory which specifies what they should be trying to do and how they should do it, two popular theories of this sort are described. Bundle of knowledge theory rests on the idea that education should impart pieces of knowledge which can be assessed by behavioral criteria with methods based on established principles of learning. Developmental stage theory holds that education should help students move through a sequence of general stages towards maturity. A third theory called component theory, is then sketched, in which the idea of general stages is disputed and the idea of component abilities of intellectual processes substituted. This theory has implications which are similar to those of stage theory if it is combined with certain moral assumptions about the goals of college education, namely that its purpose is to help students form and pursue life plans which are both rational and just. 相似文献

Research on the relationships between higher education and the world of work: Past achievements, problems and new challenges 总被引：1，自引：0，他引：1
Ulrich Teichler 《Higher Education》1999,38(2):169-190
The review of major research approaches and themes suggests that research on the relationships between higher education and the world of work has been closely linked during the recent three to four decades to changing themes of policy and practise. There were some indicators of research in this area being an agent of subordination of higher education to the employment system, being quantitative-structurally biased, tending to reproduce the actors' myths and being stuck in the over-education debate. A closer look, however, reveals that the range of research approaches is very broad and that a common core of themes and approaches emerged which provides the opportunity of examining controversial hypotheses. It is finally suggested that research in this area should be based on anticipation of likely changing conditions in the future, e.g. trends towards precarious or flexible employment, towards a mass or abundance paradigm, towards a 'life-long learning society' and towards an 'international' or 'global' labour market. 相似文献

An approach was developed to investigate the link between attributes of a children's radio program and children's judgments of appeal. Program tapes were divided into 28 segments and were rated for the presence of 30 attributes. Through multidimensional scaling analysis, attributes were organized into six clusters of Superattributes on the basis of their co-occurrence across the 28 segments. Superattributes were labeled and assigned scores that reflected the degree to which each was present in the 28 segments. A sample of 42 children 8–12 years old listened to the test tapes and provided a written judgment of their interest in the program at each segment. Results revealed that the Superattributes Instruction, Intro Talk, and Jokes were negatively associated with children's interest, while Popular Music was positively correlated with interest. In planning programs and understanding the effects of radio on children, designers and researchers should pay special attention to those formats in radio programming that are familiar to children, especially popular music and instructional material. 相似文献

Claims have been made that computer mediated communication (CMC) is a potentially highly participatory and democratic medium because it reduces the requirement to interrupt or wait your turn to speak. Such aspects of discussion have been shown to be relevant to differences in male and female participation in group discussions. In general, men have been found to take more turns and to speak longer than women in mixed sex groups. Men are also said to characteristically speak about things, take centre stage and give opinions. Women on the other hand are more likely to emphasis people rather than things, and to build and maintain relations in the way they talk. These two styles have been described as report talk of men and rapport talk of women.In this paper we describe some preliminary findings on the impact of using CMC and its effect on traditional gender participation differences. We look first at turn taking by men and women in computer conferences, and then how women in particular experience differences in the kind of contributions made to the conferences by men and women. Finally, we look at the actual contributions made by men and women and the extent they differ from each other. 相似文献

Equitable computer collaborations in mixed-gender teams have been a pressing issue for many years. While some have argued for creating single-gender teams or girls-only computer activities, our approach was different. The current study examines a three-month software design activity in which mixed teams of girls and boys (10–12 year olds) designed and implemented multimedia astronomy resources for younger students. In this context we assessed gender differences in students' levels of access to technology and how these participation patterns changed throughout the project duration. We found through our qualitative analyses that the configuration of social, physical and cognitive spaces in the project environment contributed to a positive change in girls' levels of access. We discuss the implications of these results in regard to issues surrounding the development and maintenance of gender equity in computer use and further research. 相似文献

In our current quest for excellence, we often miss the essential nature of it. It is trendy to use such terms as back-to-basics, gifted education, and excellence to describe a new teaching strategy or innovative educational program. It is also true that many of these programs designed for children are really intended to benefit others.Harry Morgan is Chairman of Early Childhood Education at West Georgia College in Carrollton.

Two Grade 10 classes in an urban Jamaican High School were taught over a period of one academic year in two problem solving styles: an Explicit Style derived from Charles, and an Implicit Style derived from Isaacs. At the end of the academic year there was no significant difference in their performance on a problem solving test, or on the Problem Solving Profile of the Caribbean Examinations Council's Basic Proficiency papers. The two classes performed much better than the population who sat the Basic papers on the tasks measuring Recall and Algorithmic Thinking but only moderately better than the population on tasks measuring Problem Solving.The teaching project described in this paper was supported in part by grants from the Research and Publications Fund Committee of the University of the West Indies (Mona), and the Wolmers Trust, Kingston. The author wishes to thank the Registrar and the Pro-Registrar of the Caribbean Examinations Council for permission to use the CXC papers and data in this study. A modified version of this paper was presented at the 63rd Annual Conference of the National Council of Teachers of Mathematics held in San Antonio, Texas in 1985. 相似文献

Fifty-five college women enrolled in competency-based, humanistic or self-directed education programs completed their California Personality Inventory and listed five reasons for selecting their program. CPI results indicated that self-directed students scored lower than other students on the Femininity Scale (p.001). Using Chickering's seven vectors of change as a framework, the study found competency-based students identifying purpose and competence, humanistic students identifying inter-personal relationships and integrity, and self-directed student identifying autonomy and purpose as reasons for enrolling in their nontraditional programs. The study used these results to question the mythology that adherents to different programs are of different personality types and to argue that differences in perceptions of purpose in education distinguish students in the three programs. 相似文献

“It's Easier to Be Yourself When You Are Invisible”: Female College Students Discuss Their Online Classroom Experiences 总被引：6，自引：0，他引：6
Patrick Sullivan 《Innovative Higher Education》2002,27(2):129-144
There has been considerable scholarly interest in issues related to gender in the classroom, especially in terms of finding ways in which classrooms might be configured to be more welcoming--and less chilly--to female students. There is some evidence to suggest that the online learning environment may provide educators with opportunities to achieve a more female-friendly classroom, and this study was designed to gather information about that question. 125 female college students who had completed at least one online, college-level class were invited to discuss their experiences learning online. These data show that female college students respond to the online environment in a variety of ways. A small group of students indicated that they did not enjoy learning online, while others expressed mixed feelings. The majority, however, had positive things to say about their online classroom experiences; and of these, a large number identified anonymity as the most important positive aspect of the online learning environment. 相似文献

In spite of advances in course design software and experience with online offerings, the question of how web-based education affects teaching and learning remains largely unanswered, and the terrain of online learning remains largely unmapped. In this paper, through the stories of 10 faculties of education and one computer science instructor in Ontario, we map out a small piece of the frontier of web-based course delivery and plot a course for future exploration. We argue that most existing offerings take the form of a Lone Ranger or Greenhorn approach but that there is a need to move toward a strategic institutional Wagon Train approach that consolidates and integrates support for online teaching and learning. We argue, as well, that failures in online instruction cannot simply be attributed to improper instruction or inappropriate course design. Rather, at least part of the problem locates in the ways in which conversation is structured in the online environment. 相似文献
