In this article, we describe an innovative capstone course for preservice K-8 teachers integrating action research and a unifying theme in science (AAAS in Science for all Americans. Oxford University Press, New York, 1989; NRC in National science education standards. National Academy Press, Washington, DC, 1996). The goals of the capstone course are to increase student knowledge of the unifying theme, improve written communication skills, and introduce students to educational research. We provide evidence that each of these goals is met. Student growth in theme knowledge is demonstrated through concept maps, questionnaires, and previously reported assessments. Improved writing ability is demonstrated using the spelling and grammar checking feature of Microsoft Word. The analysis of action research reports demonstrates that students are able to connect their action research project results to previous research.  相似文献

The primary thesis of this article is that undergraduates of any major can understand the important theories of computer science (CS) and the relevance of computing technology. We propose that by conceptualizing CS service courses as liberal education classes that emphasize such topics, we can move students from a state of technological ignorance and fear to one of understanding and appreciation of technology. Here, we provide an instance of such a course. A detailed explanation of the course and student and instructor evaluations are described and discussed.  相似文献

Open Systems are computing systems which are based on industry standards and nonproprietary multivendor components. As an increasing number of computing installations move away from single‐vendor proprietary architectures to more and more open architectures, academic institutions are increasingly faced with the responsibility of appropriately introducing open systems concepts into the undergraduate curricula. Using funding from the National Science Foundation, an open systems computing laboratory was recently set up at the University of Michigan‐Dearborn. The laboratory is based on the three most popular computing platforms today in the PC to Workstation range; namely IBM/PC, Macintosh, and Sun/UNIX. Supporting equipment include a postcript printer, a Novell network, a tape mass storage, and appropriate software and interfaces. A three credit‐hour course titled Open Systems Computing was offered in Summer 1995 to computer science and computer engineering majors. The course utilized the laboratory fully. This paper describes the design and implementation of the laboratory. Initial experiences with the course and laboratory are also described. Student enthusiasm about the course and laboratory was much higher than anticipated. A side benefit of the course was the ability to introduce several contemporary computing‐related topics which would have otherwise been omitted from the curriculum.  相似文献

This study tracked the influence of explicit reflective instructional methods on cultural values, ethical and intellectual development, and the relationship of these with preservice teachers' views of nature of science (NOS). The researchers used the Views of Nature of Science Form B (VNOS B) to describe NOS views, the Learning Context Questionnaire (LCQ) to classify preservice teachers' ethical and intellectual positions using Perry's scheme, and the Schwartz Values Inventory (SVI) to measure preservice teachers' cultural values. The interventions took place in two concurrent courses: a science methods course, and a foundations of early childhood course. The science methods course explicitly emphasized NOS throughout the semester, and the foundations of early childhood course reinforced these ideas through cultural activities that stressed empirical evidence. Analysis of data showed relationships between preservice teachers' Perry positions and responses on the VNOS B with those at higher positions exhibiting more informed NOS views. Relationships between preservice teachers' NOS views and their cultural values were identified, such as those at the dualism position holding achievement more highly for scientists than those at other Perry positions. The values preservice teachers held personally were different from those they held as important for scientists. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 45: 748–770, 2008  相似文献

Computer science education should not be based on short-term developments but on content that is observable in multiple domains of computer science, may be taught at every intellectual level, will be relevant in the longer term, and is related to everyday language and/or thinking. Recently, a catalogue of central concepts for computer science education such as algorithm, computer, and data has been empirically determined. This paper now concentrates on central processes relevant for computer science education. Experts of computer science rated 44 general-education processes regarding four criteria. By using a cluster analysis approach the following central processes for computer science education have been identified: problem solving and problem posing, analyzing, generalizing, finding relationships, classifying, and investigating.  相似文献

Abstract

In the critical tradition, environmental education discourse interrogates how knowledge constructs experience. But environmental education also emphasises perceiving, understanding and responding to “more-than-human” beings and processes. These two motivations are in tension. One problem is that the epistemological orientation driving the critique of knowledge seems to render access to something more-than-human a priori impossible. But environmental education squanders its promise and its dream if only ever permitted to talk about the natural world with scarequotes. Our field urgently needs to develop a realism robust against epistemologies that construct impassable barriers between humans and the rest of creation. I propose that this starts with radically reconceiving the nature and relationship between similarity and difference, interpreted in this article as the dynamic between theme and variations. Reworking Windelband’s distinction between idiographic and nomothetic research, I suggest that the relationship between theme and variation manifests a fundamental ontological pattern that pervades all things. “Theme and variation” proposes a unifying metaphysical duality in which the more-than-human reveals itself in how things suggest, conform to, modulate, and violate generalisation. Acknowledging and investigating this is part of restoring to other beings and processes their metaphysical, aesthetic, and ethical status, from the skies to the psyche.  相似文献

Responses to a written beliefs test for 178 eighth grade students and interviews with a subset of the students are analysed to investigate students' beliefs about the tentativeness of scientific knowledge and about the autonomy and strategies appropriate for science learning. These three dimensions of beliefs are salient because they align with the image of science teaching promoted by current reform movements. Analyses focus on change in beliefs and relationships among dimensions of beliefs and between those beliefs and students' understandings of science concepts. Results show that students' beliefs do not change much during the one-semester course. Students who view scientific knowledge as tentative also try to understand science. Autonomous students do not hold the most productive learning strategies, though students with low autonomy develop significantly less coherent understandings of science concepts. Instructional implications focus on potential roles of teachers and technology in promoting productive beliefs about scientific knowledge and science learning. Implications for individualized instruction follow classroom-level implications.  相似文献

Abstract

Students in my on‐campus literature classes have made good use of a series of computer programs that I have created for text analysis. I offered a course via the World Wide Web that provided 14 of my programs to students throughout the world. My course taught those students how to use the programs, and as they completed the assignments, students not only learned to use software for literary analysis, but they also often gained new kinds of insights into the study of texts.  相似文献

This study explored preservice teachers’ views of their own cultural values, the cultural values they believed scientists hold, and the relationships of these views to their conceptions of nature of science (NOS). Parallel assignments in a foundations of early childhood education and a science methods course required preservice teachers to explore their own cultural backgrounds and their perceptions of the cultural backgrounds of scientists. The Schwartz Values Inventory was used to measure preservice teachers’ personal cultural values and those they perceived of scientists. The Views of Nature of Science version B questionnaire and interviews assessed teachers’ conceptions of NOS. Copies of student work were collected and sought for themes indicating how preservice teachers perceived scientists’ cultural values and how those perceptions changed over time. We found that from the beginning to the end of the semester, preservice teachers perceived fewer differences between their own cultural values and those they perceived scientists held, though they did not change their own cultural values. We found that preservice teachers’ NOS conceptions improved, and that they were related to both their cultural values and those they perceived scientists held. Preservice teachers who indicated the fewest differences between their own cultural values and those they perceived scientists held the most informed conceptions of NOS.  相似文献

Choices in science--allocation of research funds, selection of research topics, interaction with research subjects (animals, environment, other humans), etc.--often, if not always, include some ethical considerations. Future scientists need skills to deal with and discuss ethical problems, and for that reason we have developed and evaluated one approach to including ethics in a life science curriculum. Our aim has been to support the development of students' ethical sensitivity. The key element in our teaching choices has been the importance of nurturing students' personal moral agency, i.e. their individual skills and responsibilities in moral decision-making, with an interactive teaching approach. The ethics programme was evaluated by extensive course evaluation and using three moral development measures: TESS, DIT and Perry questionnaire. The short ethics programme of three discussions was found to support the development of students' ethical sensitivity.  相似文献

Studies (for example, Dellaportas in Making a difference with a discrete course on accounting ethics. J Bus Ethics 65(4):391–404, 2006; Saat in An investigation of the effects of a moral education program on the ethical development of Malaysian future accountants, 2010) on final year accounting students show that industrial training has a positive impact on the ethical development in a way that students improved in their ethical judgement after attending a 6-month training. Thus, this research aims to evaluate the influence of industrial training in the development of ethical awareness among final year students from a Malaysian public university. These students were from multiple academic backgrounds—engineering, science and social science. A pre and post study was adopted in order to achieve the objectives. A set of survey was distributed to students before and after they have attended industrial training. In assessing students’ ethical awareness, 15 business-related and workplace ethical situations were given and students had to rate their acceptance on these situations from not acceptable (1) to most acceptable (7). From the findings, it can be observed that although the level of ethical awareness among students is fairly good, industrial training has minimal impact in improving or developing students’ ethical awareness. The impact is such because students who undergone industrial training may have observed certain behaviour that they thought are acceptable in a workplace; this may have changed the way students perceived their acceptance on the situations.  相似文献

Abstract

The article defines the ‘young’ as those who are, to be blunt, computer illiterate of whatever age they be, and considers what steps they should take to be able to understand and make educated use of the information highway. It is of course a very quick run through a course which may well take many months. The article is not for experts in the field, but it may remind them of their earlier days when they first came across data processing.  相似文献

Abstract

Understanding climate change is becoming an urgent requirement for those in education. The normative values of education have long been closely aligned with the global, modernised world. The industrial model has underpinned the hidden and overt curriculum. Increasingly though, a new eco-centric orientation to economics, technology, and social organisation is beginning to shape up the post-carbon world. Unless education is up to date with the issues of climate change, the estate of education will be unable to meet its task of knowledge transfer. This article covers the basic science and ethical policy debates, and begins to outline the questions that will necessarily entangle education as we orientate ourselves to the new world that is upon us.  相似文献

BackgroundState child welfare agencies collect, store, and manage vast amounts of data. However, they often do not have the right data, or the data is problematic or difficult to inform strategies to improve services and system processes. Considerable resources are required to read and code these text data. Data science and text mining offer potentially efficient and cost-effective strategies for maximizing the value of these data.ObjectiveThe current study tests the feasibility of using text mining for extracting information from unstructured text to better understand substance-related problems among families investigated for abuse or neglect.MethodA state child welfare agency provided written summaries from investigations of child abuse and neglect. Expert human reviewers coded 2956 investigation summaries based on whether the caseworker observed a substance-related problem. These coded documents were used to develop, train, and validate computer models that could perform the coding on an automated basis.ResultsA set of computer models achieved greater than 90% accuracy when judged against expert human reviewers. Fleiss kappa estimates among computer models and expert human reviewers exceeded .80, indicating that expert human reviewer ratings are exchangeable with the computer models.ConclusionThese results provide compelling evidence that text mining procedures can be a cost-effective and efficient solution for extracting meaningful insights from unstructured text data. Additional research is necessary to understand how to extract the actionable insights from these under-utilized stores of data in child welfare.  相似文献

Those of us who teach computer science courses, especially upper division courses, face a difficult pedagogical problem. What kind of activities can we provide that will help our students progress beyond the superficial level of learning yet another collection of disjointed facts and procedures? The literature on writing strongly suggests that writing assignments can help the students master difficult concepts and develop the higher level skills that should be part of their education. Short, narrowly focused writing assignments have been used effectively to supplement a wide range of computer science courses. Holistic grading and follow‐up discussions can reduce the grading burden without sacrificing the quality of the feedback.  相似文献

Industrial software development today requires a fundamental education in computer science as well as the ability to work productively and collaboratively in a team environment. Employers will therefore favor graduates who have mastered computer science and software engineering concepts and can apply them while developing a software system. To produce computer science graduates possessing the skills necessary to succeed in the workplace, team‐oriented software engineering courses with real projects (and with real clients) are increasingly emphasized. It is, however, difficult to successfully present a software engineering course that covers software engineering concepts and offers opportunities to apply them during a project in a team environment. The difficulties lie in project selection, team formation, team and project organization, process management, and, finally, grading. The objective of this article is to discuss these difficulties and provide suggestions for alleviating or avoiding them.  相似文献

This project is demonstrating the feasibility of using the object‐oriented paradigm to teach students software design in a nonprogramming context. The program, developed using principles of user‐based, prototyping design, teaches students to create responsibility‐driven designs of computer games. Investigations with high school students with little or no knowledge of computers and senior computer science majors have demonstrated that students can indeed learn to use Class‐Responsibility‐Collaborator (CRC) cards to produce creditable high‐level designs in a relatively short time whether or not they have programming experience and can generalize what they have learned to a new design. Although the computer science majors created more complete designs and demonstrated a deeper understanding of the design process than the high school students, these students still found the experience valuable. Both sample groups generally found the process interesting and relatively painless.  相似文献

Abstract

Through qualitative analyses of narratives of what students and faculty wanted in their relationships, the authors identified three themes. The Teaching/Learning Environment theme illustrated needs for nurturing, open, nonthreatening, and respectful attitudes in student-faculty relationships. Exchange of Information students reported a desire to learn and interact with each other, but not with the instructor. With regard to Mentor/Peer Association theme, students wanted to develop networks of friends to help with course work, whereas teachers wanted to find principles of effective teaching to help students learn. Applications of this data for improving student-faculty interactions and instructional processes are discussed.  相似文献

This study is a follow-up to one published in computer science education in 2010 that reported preliminary results showing a positive impact of service learning on student attitudes associated with success and retention in computer science. That paper described how service learning was incorporated into a computer science course in the context of the Students & Technology in Academia, Research, and Service (STARS) Alliance, an NSF-supported broadening participation in computing initiative that aims to diversify the computer science pipeline through innovative pedagogy and inter-institutional partnerships. The current paper describes how the STARS Alliance has expanded to diverse institutions, all using service learning as a vehicle for broadening participation in computing and enhancing attitudes and behaviors associated with student success. Results supported the STARS model of service learning for enhancing computing efficacy and computing commitment and for providing diverse students with many personal and professional development benefits.  相似文献
