How can adults who watch “Sesame Street” with children facilitate the children’s recognition of the letters and numbers presented on the show? In order to examine this question, each of 95 preschool children watched three specially edited versions of “Sesame Street” with an adult who either (a) asked the child questions and provided feedback, (b) only asked questions, (c) directed the child’s attention to the screen, or (d) simply watched the shows with the child. Those children in the Questions + Feedback condition and the Questions condition scored significantly higher on a delayed posttest than did children who just watched the shows with an adult. There were no other significant differences among the treatment conditions. Results indicate that adults can increase children’s recognition of letters and numbers presented on “Sesame Street” by asking the children to name the letters and numbers as they are presented. Other interpretations are also discussed.  相似文献

Reviewing Fleeming Jenkin’s Electricity and Magnetism in Nature in 1873 an anonymous reviewer (probably James Clerk Maxwell) remarked that “at the present time there are two sciences of electricity — one that of the lecture-room and the popular treatise; the other that of the testing-office and the engineer’s specifications.” In this paper I want to look behind Maxwell’s remark and examine the relationship between the “two sciences” of electricity during the third quarter or so of the 19th century. In particular I want to look at them in terms of their instrumental technologies. How did apparatus travel between the lecture-room or exhibition-hall and the testing-office or the laboratory? How did skills cross between these different spaces? How did the earlier Victorian culture of electricity as “entertainment and edification” become transformed into late 19th century metrological culture? How did these cultures overlap and how did they differ?  相似文献

“The Scientific Method” as it has been portrayed in popular and introductory contexts has been declared a myth. The variation that one finds in introductory presentations of “The Scientific Method” is explained by the fact that there is no canonical account among historians and philosophers of science. What, in particular, is wrong with “The Scientific Method”? This essay provides a fairly comprehensive survey of shortcomings of “The Scientific Method”. Included are corrections to several misconceptions that often accompany such presentations. Rather than treating “The Scientific Method” as a useful approximation or an ideal, the myth should be discarded. Lessons can be learned for introductory pedagogical contexts from considering the shortcomings of the myth.  相似文献

“What do you think of European preschools?” “Do they have good schools in Yemen?” “What are Chinese child care centers like?” I am always taken aback when asked such questions. Of course, I'm always taken aback when someone asks what I think of kindergarten education in the United States; I never know how to answer that either. Does the question refer to kindergarten classes in the school near my home? Or kindergartens across the United States? Even if the inquirer expected an answer based on the schools which I visit regularly to supervise student teachers I would have to give a general statement, followed by some qualifying statements related to different teachers, different schools, and different school districts — all withinone county! The old adage that “All generalizations are dangerous, including this one” always comes to mind.  相似文献

Informal observations of Prolog learners showed that, despite being presented with correct information and models, students still tended to construct their own idiosyncratic explanations of events, and, characteristically, they defended these ‘stories’ fiercely when tutorial intervention was attempted. Although the stories were often so flawed that the student's future progress was potentially hampered, it was nevertheless true that learning could not have proceeded at all without them. It seems that if we are to understand the novice Prolog programmer, we need to know about these stories, their source, and what, if anything, they have in common from one learner to another. Pain and Bundy (1987) posed the question “What stories should we tell novice Prolog programmers?” in order to teach them Prolog. In our research, we ask: “What stories do novices Prolog programmers tell themselves?” in order to learn Prolog. Observational studies undertaken showed that students used tacit knowledge of human discourse processes both to interpret the language used to communicate with the computer and to interpret the behaviour of the machine. Students did not appreciate the fundamental differences between natural discourse (as takes place amongst humans) and formal discourse (as takes place between humans and machines), and confused elements of the discourse levels. This can be an effective initial learning strategy, but unless its limitations are recognised, programs are inevitably incomplete at some level. Examples from these studies are reported here with illustrative protocol fragments.  相似文献

This study investigated the extent to which early education classrooms across Indiana implemented evidence-based practices and how well the classrooms of different types of early education programs in our state compared with one another. Evidence-based effective curricula increase children’s learning compared to those that are not effective. This article addresses the question: “Are the curricula used by the teachers effective?” The 81 participating classrooms included 28 in licensed child care centers, 27 in Head Start, and 26 in public school prekindergarten. Of the 81 classrooms, 80 teachers responded to the question: “What curriculum or curricula do you use in your classroom?” We used a three-step process to determine whether each response named a curriculum based on the Head Start definition; whether studies of the curriculum met the What Works Clearinghouse (WWC) guidelines for being evidence-based; and if the WWC reviews identified the curriculum as effective in increasing children’s learning. Findings revealed that only 2 of 80 responding teachers used a curriculum determined by WWC to be effective. Other teachers used curricula that did not meet the Head Start definition, used curricula that did not meet the WWC standards for evidence, or used curricula with evidence but that were ineffective. These findings suggest that administrators and teachers should opt for a curriculum determined to be effective and to choose whether the curriculum will be math- or literacy-based since no comprehensive curriculum has been determined to be effective. A challenge for implementation is that the WWC has shown only five curricula to be effective.  相似文献

Whether your day care center or Head Start program has staff of five or twenty-five, you might wish to consider a professional development component (PDC). “What is that?” you say. “Not another thing we have to do. Isn't it enough that early childhood educators ... must be an astute purchaser, ... must be persnickety picker-and-chooser, ... must be a scavenger, ...” (Hymes, 1968, pp. 82–85) “and that programs have to meet state licensing standards or Head Start Performance Standards? Now programs must develop a new component!”  相似文献

This paper examines the question of whether there are useful general thinking skills. It offers a working definition of 'thinking skill' and identifies ways in which this concept has been over-applied. Thinking skills, used across domains, are not inevitably weak as a result of the generality-power tradeoff. Admitting that thinking skills require domain-specific knowledge for their application, it is contended nonetheless that there are general thinking skills that involve substantial amounts of domain-independent knowledge. These skills usually address 'generic thinking tasks', common mental challenges that people face in many practical and intellectual endeavours, including the 'domain of practical affairs'. The educational implications of these findings are discussed.  相似文献

This paper concentrates upon the relationship between mathematical education (ME) and critical education (CE) connected with the Frankfurt School and Critical Theory. To make the discussion as precise as possible a distinction is made between three alternatives in ME: Structuralism, pragmatism, and process-orientation. These alternatives are related to the key terms of CE in order to show the extent to which ME and CE contradict each other. The conclusion is that there does not exist any integration — nor even any close relationship-between ME and CE. Finally, this result is discussed in the light of the following two theses:
  1. It is necessary to increase the interaction between ME and CE, if ME is not to degenerate into one of the most important ways of socializing students into the technological society and at the same time destroying the possibilities for developing a critical attitude towards precisely this technological society.
  2. It is important for CE to interact with subjects from the technical sciences, and among these ME, if CE is not to be taken over by the technological development and fade away into an unimportant and uncritical educational theory.

Over the last 15 years, surveys in a range of English-speaking countries, from North America and the United Kingdom, to New Zealand and Australia, have consistently shown that employers rank oral and written communication skills as highly as or more highly than any technical or quantitative skills. However, in New Zealand there has been very little research into determining exactly what is meant by the “written communication skills” employers state they desire. A further issue in this research to date has been a lack of differentiation between employers—no study has specifically targeted the requirements of employers of science graduates. This article reports the findings of ongoing research into the expectations of science students and of employers of science graduates, and centers around several key questions:
  • What do New Zealand employers of science graduates specifically want in terms of their new hires' writing skills?
  • How can information gained from employers of science graduates be used to motivate science students to take seriously the need to develop their writing skills?
  • How can writing programs be evaluated and developed to help science students acquire communication skills that are important for their future learning and for their employment and promotion prospects?
Findings are compared with the findings of the 2004 National Commission on Writing's survey of American businesses.

In China, the philosophy of science and technology (PST) is derived from “Dialectics of Nature” (DN), which is based on Engels’ unfinished book Dialektik der Natur. DN as a political ideology provides political guidance for scientists and engineers. Therefore, since 1981, “Introduction to Dialectics of Nature” (IDN) has been an obligatory course for master’s degree students who study natural science or technology. In 1987, DN was renamed PST by the Chinese government in order to communicate and do research. The IDN teachers constitute most of the scholars who research PST. Nowadays, in China, PST includes philosophy of nature, philosophy of science, philosophy of technology, sociology of science, sociology of technology, “science, technology and society,” history of science, history of technology, management of science, and management of technology due to having too many IDN teachers. In fact, it is neither a branch of philosophy, nor a subject. The number of the IDN teachers has been increasing since 1981, which makes PST a miscellaneous collection of many branches or subjects. Finally, PST is facing two new challenges: the reduction of IDN and academic corruption.  相似文献

In recent years, instructors, academic programs, and innovative educational institutions have begun utilizing self-directed learning concepts and contract learning structures for assumed development of student self-directed learning outcomes. However, prior investigations of development of self-directed learning have been hortative in form or have examined correlative relationships of self-directed behavior with specific learner characteristics. Does learner participation in a self-directed contract learning course influence his/her future behavior and attitudes toward self-directed learning? This study examined the impact of a self-directed contract learning course upon participant self-directed learning behavior and attitudes. Findings of this study were examined from three forms of impact evaluation. Significant positive gains were noted on participant pre- and postgain scores on the Self-Directed Learning Readiness Scale (SDLRS). Course evaluations noted a majority of positive participant responses regarding perceived changes in knowledge and skill of self-directed learning as well as reported value of the course experience. The third form of impact evaluation came from observational diaries analysis. Diaries from selected students and the instructor were analyzed for major themes and transitions. A discussion of these themes and transition points are presented in a framework analysis of the Fuller and Bown “Concerns model.” Findings are discussed for their varying significance in understanding the development of self-directed learning behavior.  相似文献

This is the third symposium in our series on children's fiction (7–16 yrs) of the last decade. Owing to the length of time taken in the gatheringand ordering of the material, the terminus ad quem has been extended to 1982. Following the same procedure, we asked each of our compilers, Trish Botten, Sarah Hayes, and Val Ray, to select a list of 25 titles theyjudge to be fiarticularly worthwhile. Titles mentioned on more than one list appear under the heading “Special Mention,” with reviews by members of the Editorial Committee. The others are under the “General List” with short subject summaries. The symposium is followed by an article reviewing-the science fiction field by Brian Earnshaw, who combines the viewpoints of author and college lecturer. We hope that this feature will continue to be useful to those engaged in choosing books for children.  相似文献

The report is a translation of part of a Swedish paper entitled “On Students' Achievement in Mathematics after Finishing Comprehensive School”. The intention of the investigation was to

  • - diagnose the retention of some basic skills in some topics in algebra and geometry,
  • - reveal difficult steps in the learning processes in these topics.
  • Starting with a complicated question, e.g. the equation \(\frac{{3x - 2}}{2} = \frac{x}{3}\) a sequence consisting of 5–15 problems were constructed. Each new problem followed by the preceding one by taking away one or two details. \(\begin{gathered} 3(3x - 2) = 2x \\ {\text{ 9}}x - 6 = 2x \\ {\text{ 7}}x - 6 = 0 \\ {\text{ 7}}x = 6 \\ \end{gathered} \) is an example of a sequence belonging to the equation above. From about 10 complicated problems (“top-items”) and their sequences, in all 130 items, 10 sub-tests were put together in such a way that the pupils who took the test were not aware of the sequences but found no connection between the problems. Many surprising results were found, e.g., that the students scored higher on 14/(x+2)=2 than on 4/x=3, that the difficulty in finding the area of a triangle depended on the position of the triangle and that the problems “Simplify a/a 2, a2/a, a/a” were of quite unequal difficulty. A discussion about the students' thinking in patterns and mechanically learning ends the report.  相似文献

    The academic study of Education1 1. A capital E is used when Education refers to Education as an academic subject or discipline. A lower case e is used to refer to education as a process. View all notes (as a social, historical, and theoretical phenomenon) is complicated by the fact of our immersion in it. This paper combines Said's idea of “contrapuntal reading” with Bourdieu's notion of reflexivity to explore what happens when students on an Education course directly confront the fact of their everyday involvement in their object of study, Education. How do the questions raised by post-colonial and other critical social writers “appear” from such a position? How does the fact of our involvement complicate our theoretical or scientific knowledge of these? By means of an episodic, narrative form of writing, this paper describes a life history pedagogy for teaching a compulsory “social issues” course online to New Zealand pre-service teacher education students. As data I draw on online conversations with and between students as they engage in the production of contextualized life history interview narratives.  相似文献

    Building on Ball's (2009) Ball, A. 2009. Toward a theory of generative change in culturally and linguistically complex classrooms. American Educational Research Journal, 46(1): 4572. [Crossref], [Web of Science ®] [Google Scholar] model of generative change, we explored how two experienced literacy teachers, after completing a graduate-level multicultural literacy course, enacted the tenets of critical literacy. Ball defined teachers' generative thinking as “connecting their personal and professional knowledge with the knowledge that they gain from their students to produce or originate knowledge that is useful to them in pedagogical problem solving and in meeting the educational needs of their students” (2009, p. 47). We uncovered how teachers' generative thinking progressed over time; how they sanctioned critical literacy practices in their own classrooms; and how they continued to guide their students to question, dispute, and examine power relations. As the teachers' generative thinking grew over the two years, they continued to express tension and doubt, showing that teacher change is never linear or simple, but often situational and complex.  相似文献

    The success or failure of a school reform can be measured by whether the reform has become an accepted, effective, and sustainable part of the school's culture. For example, as the National Middle School Association (2003 National Middle School Association. 2003. Research and resources in support of “This we Believe”, Westerville, OH: Author.  [Google Scholar]) argued, “new programs must become integral to the school culture” (p. 11) before a school can call itself a “middle” school. But how can a school monitor its progress, and at what point can a school claim that a new reform or new programme has become part of its culture? Wallace's revitalisation theory (1956), Hall and Hord's Processural Structure (1986) and Hall, Wallace, and Dossett's Concerns-Based Adoption Model (1973) are used to describe the cultural revitalisation taking place with the introduction of middle schooling into Australia and specifically within 3 Queensland middle schools. Results have highlighted gaps and tension points that need to be resolved before any widespread cultural transformation can be claimed.  相似文献

    High quality provision has been one of the key aims of the current reforms in higher educational institutions across the globe since the beginning of the century and the millennium. Consequently this has led to the increasing demand for quality assurance (QA). This report identifies those institutional processes and structures that support the development of an internal quality culture in the emerging private universities in Ghana. The study bases its understanding of “quality culture” on the definition which sees it as referring to an organizational culture characterized by a cultural/psychological element on the one hand, and a structural/managerial element on the other hand. If we take our educational activity as a process, then the process (the activity) requires inputs (information, materials), resources (people, equipment, space) and control (QMS) to produce outputs (products and/or services). QA then is a culture—a way of continuously aiming to improve and do better—and the private universities in Ghana are responding to this.  相似文献
