Conclusion Afew columns ago I likened many instructional technologists to marine biologists who were afraid of water and had never been to the sea. I suppose this column claims that they really don’t practice their biology, either. It’s not that we don’t know instructional technology; it’s not even that we don’t do instructional technology; it’s that many of us haven’t yet learned tobe instructional technologists. Let’s go there. Come on, it’ll be fun.  相似文献

We report on an international study about mathematics students’ ideas of how they will use mathematics in their future study and careers. This builds on our previous research into students’ conceptions of mathematics. In this paper, we use data from two groups of students studying mathematics: those who participated in an in-depth interview and those who completed an open-ended questionnaire. We found that their responses could be grouped into four categories: don’t know; procedural skills; conceptual skills; and professional skills. Although some students held clear ideas about the role of mathematics, many were not able to articulate how it would be used in their future. This has implications for their approach to learning and our approach to teaching.  相似文献

Conclusion I applaud ISTE, AASL, AECT, and the other organizations involved for tackling the “messy work” of developing standards for the use of technology and information resources in schools. And, at the same time, I call for a “second generation” of standards that define realistic expectations for teachers based on the subjects and levels they are called upon to teach. I propose that professional organizations from each subject work with ISTE and AECT to complete this huge task, and I propose that we consider as a “next step” the creation of a set of on-line learning experiences through which teachers can gain the identified skills and knowledge by using the very technologies we’re hoping they’ll embrace in their own teaching. There’s an old saying, “If you don’t know where you’re going, any road will do.” As far as educational technologies are concerned, this is also true. For many, the goal seems to have been simply to “get more computers into the schools,” without much thought about purpose. To return to Phil Schlechty’s metaphor, It’s generally been a brief and misguided “Ready” stage (occupied with questions like “How many do we need?” “What type?” “Where?” and “How shall we connect them?”), followed by “Fire!” (the acquisition and installation of equipment). What we need is: “Ready” (the creation of appropriate teams of people who will combine their insights to plan for the district)... “Aim” (a series of discussions about what technologies can accomplish for schools and the students they serve)... “Fire” (acquisition, installation, and professional development according to plan)... “Aim” (an assessment of how well the technologies and related programs met the intended goals, and a new planning effort designed to close the gap)... “Fire” (acquisition and implementation designed to eliminate the gap)... “Aim” (another gap assessment)... “Fire” (another attempt to close gaps)..., And so on.  相似文献

Zusammenfassung Anwendungsf?higkeiten und das Interesse für neueste mediale Technik sind zu einem Kennzeichen moderner Adoleszenz geworden. Dabei spielen das Medium Computer bzw. Anwendungsweisen neuer Medien eine erhebliche Rolle. Doch die Computernutzung Jugendlicher geht über einfache technische Anwendungsweisen weit hinaus. In der Relation von Medium und Subjekt ereignen sich individuelle Identit?tsbildung und Selbststabilisierung, geschehen Suchbewegungen und Explorationen von Subjektgestaltung. Innerhalb dieser Prozesse der Identit?tsbildung und Subjektgestaltung sind Dimensionen jugendlicher Computernutzung zu beobachten, die in den Bereich der individuellen Sinngenese fallen und in den Kontext der Diskussion um Medienreligion bzw. um Formen „verflüssigter“ Religion geh?ren. Wie sich diese Formen ausdifferenzieren will der folgende Beitrag entfalten, dem ein qualitativempirisches Forschungsprojekt zugrunde liegt.
Summary Religion, Identity and Computers — Fluid forms of religion in youth culture Competency and interest for new media technology have become recognizable elements of modern adolescence. The computer and the use of new media play particularly significant roles in this context. However, adolescents’ use of computers goes far beyond simple technical application. The relationship between medium and subject influences identity formation and self-stabilization, and initiates a process of searching and exploration of individual development. Dimensions of computer use within these processes can be viewed in the context of individual processes of sense-making construction and are therefore relevant to the discussion of media religion and of so-called “fluid” forms of religion. This paper will show how the forms develop on the basis of a qualitative empirical research project.

Computers are increasingly a part of preschooler’s lives. The purpose of the present paper was to discuss research avenues employing computers as a learning tool and to analyse the results obtained by this method at the preschoolers’ learning level. Specifically this research was to determine if computer assisted instruction (CAI) was a useful tool to enhance cognitive, emotional, linguistic, and literacy skills in preschool children. CAI programmes may never replace the book and the blackboard but one should be aware that they were more accessible by young children, who learn better with pictures and sounds, and the proper use of appropriate programmes could make a considerable difference.  相似文献

This article focuses on educational enterprises outside the formal sector, such as museums, botanical gardens and interactive science centres. International research is drawn on to illuminate how design, culture, educational strategies and settings combine to affect the way in which young people respond to experiences on offer, leading to analysis of the impact of such settings in promoting learning, and the likely implications for those who staff such venues. Aikenhead’s concept of the educator as ‘culture broker’ is developed to suggest ways in which learning might be best supported. It envisages a shift from ‘delivery’ strategies targeted at large groups towards approaches which focus on what learners choose to know about using dialogue between children and ‘known and trusted people’. Analysis of observed responses in various settings is undertaken from a sociocultural perspective using the notion of communities of practice. Implications for the roles of education managers and their staff in further research are developed.  相似文献

Conclusion Which is the better choice: general item bank software or a word processor program? Your answer is dependent upon your computer skills, the amount of test development work you do, and the nature of investment your school is willing to make for software. Both have their relative strengths and weaknesses. The trade-offs between the two approaches are real, important, and in time will probably favor the item bank software. At the moment, however, we recommend a good word processing program for most teachers. What can you expect the future to bring? At a minimum, test preparation options will continue to expand and improve. We suggested earlier that the technology is changing rapidly. For example even now you can place a printed copy of test items into an optical character recognition (OCR) scanner (similar to a photocopy machine) and read the items into a digital form which either a word processor or a test generator can use. Instead of having to type your collection of test items before selecting, editing, and printing them, the computer will read them from the paper. This new scanning technology, unfortunately, requires expensive software, powerful microcomputers, and the scanner itself costs over $1000. In addition, the accuracy of the character recognition is not perfect—especially with less than the ideal printed copy from which to work. It will be years before most of us have ready access to this technology. Even better options will be available, however, don’t wait for the next major breakthrough. There will always be another breakthrough on the horizon. You can start improving your test development process now  相似文献

This paper presents the findings of a recent research project into children’s access to and use of computers in their homes. The study involved over 400 children who regularly used a computer at home. The children were aged between five and twelve and came from a variety of social, economic and cultural backgrounds in urban Sydney. Significant themes that emerged from the discussion included issues of equity and access, the variety of use of computers, the ways children learned to use them in their homes and children’s perceptions of differences between computing at home and at school. Each of these themes is discussed in terms of the implications for schools and teachers.  相似文献

The advent of computer technology in the classroom raised the issue of its appropriate use by teachers and their students alike. It has been recommended that teacher education programs provide more opportunities for teacher candidates’ use of technology including teaching their own technology-enhanced lessons. With a goal of integrating scholarship into student teaching, a teacher candidate enrolled in a graduate program in childhood education carried out a technology-enhanced research project within a professional development school. Examining the impact of the project on the teacher candidate, this article describes how one’s pedagogical content knowledge and technological competence can be developed through a research-oriented teaching experience. The article also demonstrates the emergence of a community of practice that shares the goal of providing learning spaces for the teacher candidate and young children in the context of mathematics enrichment with computers.  相似文献

This paper presents an “ecological perspective” on research with computers in science education. It is proposed that current and past research within the computer education field has been characterised by an over-emphasis on technical applications of the machinery, rather than a deeper consideration of the teaching and learning process. This tendency toward “technocentric thinking” has usually failed to take into account the important social and cognitive interactions within the computer learning environment. The view advanced here, is that an understanding of the effects of computers on students' learning can be achieved only through an analysis of the dynamic interactions between students and teachers as they work with computers in a particular environment. A theoretical framework for understanding this range of interactions is presented. Finally, an ecological model is proposed for conducting future research on the application of computers in science education.

Websites for colleges and universities have become the primary means for students to obtain information in the college search process. Consequently, institutions of higher education should target their websites toward prospective and current students’ needs, interests, and tastes. Numerous parameters must be determined in creating a school website (e.g. number of links, page size, use of graphics, utilization of dynamic elements, and menuing options). This research details a decision support framework based upon Kohonen self-organizing feature maps to determine students’ specific preferences for school websites. This research attempts to remove some of the subjectivity in designing a school website by finding the commonalities among websites that students find appealing and effective. Self-organizing feature maps are employed as a clustering method to compare the school’s current website to other sites that students find both appealing and effective.  相似文献

This forum response adds a conceptualization of harmony to Dopico and Vázquez’ investigation of pedagogy that combines citizen science, environmental and cross-cultural research, and service-learning. Placing many appropriate and significant aspects of culturally situated science education in an authentically relational context beyond the classroom, this paper calls attention to insightful contributions and new directions for research, such as the process of inducing or eluding nihilism regarding ecological issues. How can such a question be researched effectively in order to learn about the family of pedagogies emerging in response to the need for more ecologically conscious and relationally authentic teaching across many disciplines? In this paper, I use a Vygotskian framework and an abbreviated case study of agricultural service-learning from my research, drawing attention to the importance of students’ culturally-mediated construction of setting as they interact in older and newer ways.  相似文献

Critical thinking is an essential competency in the new information age. But research shows that students commonly lack critical thinking skills and hence promoting students’ critical thinking becomes crucial. This exploratory study investigated the extent to which secondary school students’ critical thinking could be promoted by writing reflections in the weblog. Students’ critical thinking was measured by using the Newman’s model. Results showed that writing reflections in the weblog could help promote students’ critical thinking and according to the Newman’s model, three categories of critical thinking were promoted the most, they were bringing outside knowledge or experience (O+), relevance (R+), and justification (J+). In addition, the study also found that the types of interaction with peers and the teacher had a more positive effect on the extent of critical thinking. Implications for other research are discussed.  相似文献

Utilizing video study methodology where participants, as well as the researcher, analyzed their own video data, this research examined the nature of students talking aloud during peer collaborations in mathematics. The findings suggest that students engage in three types of talking aloud: (1) clarification of thinking (i.e. spontaneous utterances related to the mathematical task); (2) expressions of confusion (i.e. “I don’t understand!”), with the explicit intent of eliciting support from peers; or (3) a combination of (1) and (2). The findings also show that students do not perceive other students’ talking aloud as an inter-communicative gesture. This research highlights the importance emphasizing to students that talking aloud during peer collaborations should be viewed as a potential antecedent to communicative interaction and the importance of teaching students how to listen to one another.  相似文献

Conclusions These findings are important to educational leaders, especially those in higher education, who are responsible for allocating resources for microcomputers. Recommendations for the selection of appropriate hardware can be derived from this analysis of current computer use and of expected changes. That computer facilities need upgrading in the next decade is clear. The purchase of new Macintosh and MS-DOS microcomputers would fit the needs of a majority of educational administration students. Of the program coordinators and professors with computer expertise who responded to the survey, 43 percent believe that their graduate students are gaining more access to computers in places other than the university. College of Education computer laboratories should be more open to students in educational leadership programs, and these programs should make the availability of appropriate hardware and software a priority. Understanding the extent to which educational administration programs train their students in computer use is of paramount importance in assessing curriculum development and its concomitant hardware demands. She has published reviews and articles on various aspects of computers in education.  相似文献

The CLAT provided considerable information about children’s attitudes and knowledge well beyond computer literacy. It revealed improvements in the use of language, as well as in spelling and penmanship. I understand very well that evaluation engineers would prefer to “partner with teachers” to ensure more thorough grant-funded documentation of the many and diverse process and product outcomes of computer technology expenditures (Baker, 1999). However, a simple count of computer-related terms listed by students appeared, for my limited purposes, to be both a valid and reliable indicator of at least one small aspect of computer literacy  相似文献

The introduction of computers into education raises questions such as: are computers in education effective? If they are, in what sense? What are the most effective strategies for using computers in education? How should teachers be encouraged to use them?
To answer these questions a large-scale experiment (Project Comptown) was carried out in Israel, to test ways and means under real rather than laboratory conditions. This project is a research-oriented educational intervention, applying massive computerisation of schools and their 'close environment' to two localities in Israel (Arad and Ashkelon). Our starting point was the premise that computerisation of education is an inevitable process. Consequently, turning the computer into a 'cultural tool' in schools becomes a major challenge, aiming to narrow the gap between 'school culture' and 'real-world culture'. The main objectives for Project Comptown are: [1] To create a computer culture in schools; [2] To use the computer's potential for innovative teaching and learning, both inside and outside schools. To achieve these, we identified a number of principles which we considered pre-conditions for an 'appropriate' computer strategy in schools.  相似文献

What can a computer with limited resources like time and space accomplish? Can it solve our favourite computational problem? These are the kind of questions that we implicitly ask when designing ‘efficient algorithms’. It is also interesting to know which problems cannot be solved with computers operating with limited resources, no matter how smart we are as algorithm designers. Moreover, given a problem, we would like to know the lower bound on such resources required to solve it using a given computer. This article in two parts, discusses an important technique called diagonalization for establishing such lower bounds. In this part we will fix a model of a computer —indeed, one that is as powerful as any other known mechanical model — and explore some important features of this model. In the second part, we will introduce diagonlization, its applications and potential shortcomings.  相似文献

The notions of ‘idealisation’ and ‘approximation’ are strongly linked to the question of ‘how our theories represent the phenomena in their scope’. Although there is no consensus amongst Philosophers on the nature of the process of idealisation and how it affects theoretical representation, at the level of science education much can be gained from the insights of existing philosophical analyses. Traditionally, teaching methodologies treat the observed divergence between theoretical predictions and experimental data by appealing to the more common-sensical notion of ‘approximation’. The use of the latter notion, however, to explicate discrepancies between theory and experiment obscures the theory/experiment relation. It does so, I argue, because from the viewpoint of scientific modelling ‘approximation’ either depends upon or piggybacks on ‘idealisation’.  相似文献

Floating point numbers are an important data type in computation which is used extensively. Yet, many users do not know the standard which is used in almost all computer hardware to store and process these. In this article, we explain the standards evolved by The Institute of Electrical and Electronic Engineers in 1985 and augmented in 2008 to represent floating point numbers and process them. This standard is now used by all computer manufacturers while designing floating point arithmetic units so that programs are portable among computers.  相似文献
