Abstract This paper gives an overview of the problems involved in visualizing humans in a three‐dimensional scene, and looks at the history and development of human shape modelling, human motion control, and modelling of human characteristics and clothing to produce computer‐generated actors. 相似文献

A study of Norwegian science textbooks for grade 8 indicates an individualistic image of science where individual scientists are discovering truth, through experiment. Scientific rationality is grounded in procedures of inquiry alone and not in debate and argumentation within scientific communities. The communal aspects of science tend to become visible in historical examples where science did not function properly due to prejudices or ignorance. Furthermore, science proper and school science are not differentiated between, and 'scientific knowledge about nature' and 'nature' are one and the same. The discourse identified is well suited to provide students with broad and general knowledge about natural and everyday phenomena. However, it is less suitable for teaching about the scientific enterprise in contemporary society. This is worrying for students' scientific literacy as future adults, as this dimension is essential for understanding the nature of science and for democratic citizenship in socio-scientific issues. 相似文献

Schools in England are currently being asked to pay greater attention to the issue of educational inclusion. This paper reports some of the findings of a collaborative action research Network that was set up to address the implications of this trend. The Network involves teams of university researchers in working with practitioners in order to encourage the development of inclusive practices. As a result of this work, it is argued that the development of such practices is not about adopting ‘recipes’ of the sort described in much of the existing literature. Rather, it involves social learning processes that occur within a given workplace. The paper attempts to provide deeper understandings of what these processes involve. To assist in this analysis use is made of the idea of ‘communities of practice’, as developed by Etienne Wenger, focusing specifically on the way he sees learning as a characteristic of practice. It is argued that the development of inclusive practices involves collaborative working arrangements; that they can be encouraged by engagement with various forms of evidence that interrupt ways of thinking; and that the space that is created through such interruptions can enable those involved to recognize overlooked or, indeed, new possibilities for moving practice forward. 相似文献

The impact of a college and career counseling program on economically disadvantaged gifted students and their subsequent college adjustment was assessed. Fifty‐five students from public high schools in a major urban school district in the midwest were compared to a group of economically advantaged students who participated in a special summer program for high school students at a private midwestern university. Results indicate that both before and after the program, the groups were similar with respect to the basis for their college choices, motivation to attend college, and career readiness. The economically disadvantaged students changed their plans to finance college as a result of the program and expected college to be significantly more lonely. A three‐year follow‐up revealed that economically disadvantaged gifted students were more likely to enroll at in‐state colleges, to experience college as significantly more boring, dull, and snobbish, and to have more difficulty adjusting socially and forming attachments to their universities. 相似文献

The idea of using science notebooks as a classroom assessment tool is not new. There is general agreement that science notebooks allow teachers to assess students' conceptual and procedural understanding and to provide the feedback students need for improving their performance. In this study we examined the use of science notebooks as an unobtrusive assessment tool that can also be used by individuals outside the classroom (for example, school district personnel), and as a means for obtaining information about students' learning and their opportunities to learn. More specifically, in this study students' science notebooks were used as a source of data about the (a) implementation of a curriculum's intended activities, (b) students' performance, and (c) quality of teachers' feedback. Our results indicated that: (1) Students' science notebooks can be reliably scored. Unit implementation, student performance, and teacher feedback scores were highly consistent across raters and units. (2) High and positive correlations with other performance assessment scores indicated that the student performance score can be considered as an achievement indicator. And (3) low performance scores across the two units revealed that students' communication skills and understanding were far away from the maximum score and did not improve over the course of instruction during the school year. This result may be due, in part, to the fact that no teacher feedback was found in any of the students' notebooks across the six classrooms studied. This may reflect some characteristics of the teachers' assessment practices that may require further professional development. 相似文献
