Alan Chalmers, in What ius this thing called Science?, presents inductivism as a naïve view of science which has been disproved. However, the arguments he bases this conclusion on either depend upon a stilted view of inductivism or affect a very broad range of positions, including Chalmers' own. I argue that a broadly inductivist view of science, including its observational base, is precisely the approach required.

When a liberal arts college decides to include computer science as one of its academic disciplines, a number of questions arise. What is an appropriate curriculum? What sort of laboratory support does this new discipline need? How does a small liberal arts school attract, retain, and evaluate faculty in this area? Do computer science faculty become a separate department or remain joined with mathematics or some other discipline? In short, what must be done to put computer science on equal footing with mathematics and other scientific disciplines? This paper addresses these questions.  相似文献

In this study American preservice science TEACHERS' responses on Kimball's Nature of Science Survey (NOSS) were used as a basis for analyzing the sense of the nature of science held by a group of Nigerian preservice science teachers. From an item-by-item comparison two salient differences were noted. These differences are quite interesting and important, and one would expect to see replication attempts in the near future. The primary difference was that the Nigerian students were much more inclined to see science as a way of producing useful technology. Given the national interests of a developing nation this is an understandable perception and one common among government policy makers. Nevertheless, it is a view with potential long-range dangers if this view of science is effectively transferred from teacher to student. For example, such a view is likely to raise false expectations in the general population, which when not achieved could result in widespread rejection of science. The second distinctive of the Nigerian students' sense of the nature of science had to do with the openness of science. These students perceived scientists as nationalistic and secretive about their work. This finding is troubling and indicates an important line of investigation: What image of science, especially Western science, is carried in the international media? How is that image understood in non-Western nations? What are the implications for international scientific cooperation?  相似文献

In this essay the importance of spirituality (or ethics) in the life of a research scientist is explored. The following four questions are considered: a) Why should the problem be studied? What are the benefits? and For whom? b) How should we approach this problem? c) What if the results of this investigation contradict other theories? What should we do in case of disagreements? and, d) What are the consequences of this study? Who or what is going to be harmed? What are the effects on the environment?

This article first examines didactics from an epistemological perspective.

Didactic analysis grasps knowledge as something circulated and/or transmitted. It is distinguished from sociological and psychological approaches to the learning act that legitimize the sociology of education, and from cognitive approaches.

Modifying the learner's individual knowledge so that it conforms to institutional knowledge is a scholastic goal that, in our view, defines the field of didactic research.

The second part of the article proposes answers to these questions: What is the status of the notions taught by the discipline? How are these notions constituted? What is the role of values and knowledge in school exercises and school goals? And what is to be understood by literary culture?

Computing is anticipated to have an increasingly expansive impact on the sciences overall, becoming the third, crucial component of a “golden triangle” that includes mathematics and experimental and theoretical science. However, even more true with computing than with math and science, we are not preparing our students for this new reality. It is appropriate and compelling therefore to consider how computer science can be fundamentally integrated into science education. This study is a ten-year review (1998–2008) of the Journal of Science Education and Technology, with the following research questions in mind: What are the intersections at the K-16 level between science and computing? What do K-16 science educators already know about the newly emerged field, computational science?  相似文献

Accepting that scientific literacy is the primary purpose of science in the compulsory years of schooling leads to the question ‘What does scientific literacy mean in a particular community?’ This paper reports a study designed to provide some insight into that question. Data were gathered through interviews with a sample of community leaders, in the state of Victoria, Australia, about their views of the purposes of school science.

The data reveal that, although most of those interviewed had no formal post‐school science education, their life experiences provided them with useful insights into the question raised. The wisdom of such people could make an important contribution during the initial stages of curriculum development in science.

As people successful in their own fields, the study participants were lifelong learners. Consequently, their responses suggest that a primary focus of school science must be to provide students with a framework that will enable them to continue learning beyond schooling. This is not just a matter of knowledge or skills, but of feeling comfortable with science.

The methods used provide a useful example of how views about education can be gathered from thoughtful, non‐expert community members. In this instance, they allowed a reconceptualization of the purposes of school science. These community leaders argued for an education for ‘science in life’ rather than an education about science.  相似文献

Abstract

This article addresses the following questions: What impact does using the theoretical framework of new literacies have on understanding language, literacy, and learning practices today as technologies are constantly being developed and used? What is the state of research in this area? What are some new directions the field might take in order to develop in new ways? The conclusion suggests some possibilities for new research questions and positions in relation to new technologies.  相似文献

In this forum paper, I respond to issues raised by Kristina Andersson and Annica Gullberg in their article titled What is science in preschool and what do teachers have to know to empower children? (2012). I seek to continue the discussion begun with Andersson and Gullberg’s paper, by further exploring the questions they introduce to guide their paper: “What is science in preschool?” and “What do teachers have to know to empower children?” In particular, I elaborate on the value of drawing on multiple perspectives and different epistemological frameworks, and I argue for the need for a reconceptualized notion of science as a school discipline; one that acknowledges the multifaceted ways in which young children engage in science.  相似文献

There is substantial evidence that scientific teaching in the sciences, i.e. teaching that employs instructional strategies that encourage undergraduates to become actively engaged in their own learning, can produce levels of understanding, retention and transfer of knowledge that are greater than those resulting from traditional lecture/lab classes. But widespread acceptance by university faculty of new pedagogies and curricular materials still lies in the future. In this essay we review recent literature that sheds light on the following questions:
  • What has evidence from education research and the cognitive sciences told us about undergraduate instruction and student learning in the sciences?
  • What role can undergraduate student research play in a science curriculum?
  • What benefits does information technology have to offer?
  • What changes are needed in institutions of higher learning to improve science teaching?
We conclude that widespread promotion and adoption of the elements of scientific teaching by university science departments could have profound effects in promoting a scientifically literate society and a reinvigorated research enterprise.  相似文献

Background:?The study investigated a small range of cognitive abilities, related to visual-spatial intelligence, in adolescents. This specific range of cognitive abilities was termed ‘graphic abilities’ and defined as a range of abilities to visualise and think in three dimensions, originating in the domain of visual-spatial intelligence, and related to visual perception and the ability to represent space. The educational importance of graphic abilities has received minimal attention from the educational community and, consequently, plays a limited role in educational practice.

Purpose:?In order to understand the particular educational importance of this range of cognitive abilities, we investigated how graphic abilities are connected with the performance and the subject preference of adolescents in several academic areas. Our hypotheses were, first, that there is a high degree of correlation between developed graphic abilities and high performance in mathematics and science, and second, that there is a high degree of correlation between developed graphic abilities and personal subject preference in these two areas.

Sample:?The sample consisted of 60 14-year-old students (30 girls and 30 boys) attending a public secondary school in a small town in northern Greece. The entire sample had followed the same mathematics courses, which did not involve any geometry or spatial representation tasks.

Design and methods:?We identified and defined a specific range of three graphic abilities, related to visual-spatial intelligence, and we investigated these abilities in the sample through several visual-spatial tasks designed for the study and measured the sample's performance in these tasks. The degree of adolescents' graphic performance (that is, the performance in these visual-spatial tasks) was correlated with their performance in mathematics and science and with their subject preference (mathematics, science and language).

Results:?Our findings confirmed both hypotheses. A high degree of correlation was found between developed graphic abilities and high performance in mathematics, and a lower but still significant degree of correlation was found between developed graphic abilities and high performance in science. The findings support the second hypothesis as well, suggesting that children with developed graphic abilities reported that their favourite subject was mathematics and second favourite subject was science.

Conclusions:?The research suggested that there is a particular relation between the level of graphic abilities performance and children's performance and in preference for mathematics and science. That is, children with developed visual perception, visual thought and representational skills are actually better with numbers and physical concepts. This particular relation might be relevant to the overall cognitive development of children, especially with respect to the increasingly developing communication technologies, and it would seem to deserve more attention and extended research from the educational community. The authorial position is that education would gain from a better understanding of: the nature of graphic abilities, how we can develop this range of abilities and how the development of visual thought and graphic expression contributes to several curriculum subjects.  相似文献

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students’ interests in participating in opportunities to do real science? What are the discursive resources they draw on to introduce authentic science to students? The purpose of this ethnographic and discourse-analytic study is to investigate the ways in which the activities of scientists are discursively presented to high school students in a biology/career preparation course. Data sources were collected by means of observation, field notes, interviews, and videotaped lessons in an eleventh-grade biology/career preparation course. Drawing on discourse analysis, we investigate the discursive resources—or, more specifically and technically, the interpretative repertoires—teachers used to explain and promote opportunities to engage students in real science activities. Our analysis identifies and characterizes six types of interpretative repertoires: specialized, a-stereotypical, relevant, empirical, emotive, and rare-opportunity. To better understand the “big picture” of how these discursive resources are drawn on in the classroom, we also report on the frequencies of the repertoires in the discourse and the ways in which repertoires changed in the course of teacher-student interactions. The findings of this case study offer teachers and researchers with a better understanding of how specific forms of discourse—i.e., the repertoires—can serve as resources to enhance teacher-introduction of authentic science to students and provide students a bridge between school and authentic science.  相似文献

Background: Inquiry-based science education (IBSE) is suitable to teach scientific contents as well as to foster scientific skills. Similar conclusions are drawn by studies with respect to scientific literacy, motivational aspects, vocabulary knowledge, conceptual understandings, critical thinking, and attitudes toward science. Nevertheless, IBSE is rarely adopted in schools. Often barriers for teachers account for this lack, with the result that even good teachers struggle to teach science as inquiry. More importantly, studies indicate that several barriers and constraints could be ascribed to problems teacher students have at the university stage.

Purpose: The purpose of this explorative investigation is to examine the problems teacher students have when teaching science through inquiry. In order to draw a holistic picture of these problems, we identified problems from three different points of view leading to the research question: What problems regarding IBSE do teacher students have from an objective, a subjective, and a self-reflective perspective?

Design &; method: Using video analysis and observation tools as well as qualitative content analysis and open questionnaires we identified problems from each perspective.

Results: The objectively stated problems comprise the lack of essential features of IBSE especially concerning ‘Supporting pupils’ own investigations’ and ‘Guiding analysis and conclusions.’ The subjectively perceived problems comprise concerns about ‘Teachers’ abilities’ and ‘Pupils’ abilities,’ ‘Differentiated instruction’ and institutional frame ‘Conditions’ while the self-reflectively noticed problems mainly comprise concerns about ‘Allowing inquiry,’ ‘Instructional Aspects,’ and ‘Pupils’ behavior.’

Conclusions: Each of the three different perspectives provides plenty of problems, partially overlapping, partially complementing one another, and partially revealing completely new problems. Consequently, teacher educators have to consider these three perspectives.  相似文献

Observations and other forms of perception are fundamental to the practice of science. These involve attention to a stimulus, and discrimination and categorization of the sensory input. The available evidence indicates that perception improves with practice; that it is helped if distinctive and discriminatory features are identified and are highlighted; and that this can be done with contrasting examples. Knowledge of categories into which stimuli may be sorted, and of relevant language, may provide a framework for perception.

The interpretation of a perceptual stimulus is influenced by previously‐learned knowledge, intellectual skills and cognitive strategies, and by the person's mental set.  相似文献

Abstract

This article describes and analyzes actors' experiences of distance learning systems in a wide variety of cultural and organizational contexts. In line with the project of this special series of issues, results of research, much of which is longitudinal, allow us to suggest answers to the following questions: Who are the actors of distance learning? How has their experience of learning systems evolved over the last thirty years? What roles have information and communication technologies (ICTs) played in this evolution? How do actors assess the effects of these learning systems on themselves, on the system itself, or on the organization? What are the future perspectives?  相似文献

This study is part of a cross-national research entitled In the past and now: Constructivist practices in teaching chemistry—Bulgaria, the Balkans and Europe. The purpose of the research is to explore science secondary classroom environments in terms of the constructivist approach. The study has been carried out at international schools and state schools in Albania, Kosovo, Romania and Turkey. The data collection methods were three surveys: the What Is Happening In This Class? (WIHIC), the Constructivist Learning Environment Survey (CLES) and the Test of Science-Related Attitudes (TOSRA). The questionnaires were given to 747 secondary school students. The results show that in the majority of the surveyed classrooms, a blended traditional-constructivist type of environment is present. The highest scores for all three questionnaires were given by students of the international school in Kosovo. The traditional and test-oriented teaching in the Turkish schools surveyed explains the low degree of satisfaction and enjoyment of science lessons among Turkish students.

A lot of attention has been given to the role failure plays in learning and innovation. Yet, we know little about the conditions necessary for the experience to result in positive outcomes. In this study, we sought to answer three research questions: (1) What is the relationship among attend, interpret, and respond when experiencing failures within making-related activities? (2) How does youths’ and educators’ noticing of failure within making-related activities differ by tasks? (3) How does youths’ and educators’ noticing of failures within making-related activities differ by context? To address these questions, we used data collected from youths participating in making experiences in three different contexts: schools, a science museum, and an afterschool program run by science museum educators. Analysis of approximately 90 h of video revealed differences in how youths and educators attended, interpreted and responded to failures that suggest differences in the sophistication of their response. Educational implications from these findings support less direct oversight by educators and increased use of techniques to have the youth demonstrate positive troubleshooting behaviors.
