ABSTRACTAs part of a 3-year longitudinal study, 136 sixth-grade students completed an engineering-based problem on earthquakes involving integrated STEM learning. Students employed engineering design processes and STEM disciplinary knowledge to plan, sketch, then construct a building designed to withstand earthquake damage, taking into account a number of constraints. On testing, students redesigned to build an improved structure. Using a framework of design processes, we report on the students' capabilities in planning, creating annotated sketches, and transforming these into 3D models. An understanding of core STEM concepts was apparent in their responses, including shape properties, stability, rigidity, balance, strength, and engineering techniques. Group problem solving involved moving iteratively between design phases, frequently revisiting problem scoping, being cognizant of the problem goal, boundaries and constraints, and appreciating design sketches as guiding constructions. Students were also observed to consider a number of problem components simultaneously, indicating their capabilities in handling the complexity of the task. 相似文献

This article considers how course design accommodates the adaptation of L2 students into the early stages of the master's dissertation (Social Sciences and Humanities) at a UK university. I present a contrastive process-oriented analysis of two students' experiences on different courses, extracted from a 13-month ethnographic study in which students' self-reports (journals; interviews) were triangulated with their assignments, interviews with lecturers and classroom observation. I identify two ‘literacy events’ in the early stages: discussing the topic and preparing the proposal. In order to make visible these events, I deploy Lave and Wenger's Community of Practice model, while taking a post-structuralist view of learning as a dynamic between language, identities, power relations, affordances and agency. Findings show unequal support for these events on the two courses; I argue that this exemplifies significantly different ideologies relating to the accommodation of L2 students, and discuss implications for course design. 相似文献

Interviews were conducted with 29 part-time taught postgraduate (TPg) students to determine forms of teaching and curriculum which motivated their learning. The study was conducted in an open exploratory manner to investigate the aspects of pedagogy or curriculum design which particularly motivated the TPg students which were in any way distinct from typical undergraduate teaching. As most of the TPg students were mature professionals working in a field connected to the course they had enrolled in, they were able to identify relevant knowledge, skills and abilities which ought to be included in the content or curriculum. This distinguishes them from typical undergraduate students. The TPg students appreciated in-class discussion so that they could share experiences and expertise. The interviewees preferred assessment tasks that related to their professional practice. Teaching and learning for TPg students should recognise the expertise of the students and draw upon it as a valuable learning resource. 相似文献

This case study describes the multipurpose use of scenarios in a large multinational research project (MOBIlearn) whose aims are to design and develop a pedagogically sound mobile learning environment. Maintaining effective communication and design focus in large consortia is a well‐known problem (see Carroll, 2000), and we describe the role of scenarios in addressing this. Scenarios were initially used to simply envision the future system in order to inform design, but as the project progressed, the role of the scenarios grew to encompass (i) relating system design and implementation to pedagogy by providing a common frame of reference for developers and pedagogic experts; (ii) through a process of refinement, defining the evaluation strategy for the user trials; and (iii) allowing us to keep the user at the heart of the development project. Thus, scenarios helped to resolve the difficulty identified by Taylor (2004) of how to bring together the relatively high level issues of pedagogic evaluation and the more technical user‐centred system evaluation. The development of a first‐aid training scenario is used as an illustrative example. 相似文献

Since their inception in 1993 at an Australian university, the workshop tutorials in physics have evolved and grown beyond the initiating department. In this paper, we adopt an interpretive perspective to: (i) reflect on why the tutorials continue to be successful; (ii) use models from literature to understand that success; and (iii) abstract key features that can inform scholarly inquiry into teaching and learning in higher education in other contexts and discipline areas. Practitioner (action) research and design‐based research not only provide useful methodological frameworks that support the success of the workshop tutorials, but they also offer a worthwhile methodological strategy for fostering scholarly inquiry into university teaching and student learning. 相似文献

Inquiry learning is an educational approach in which learners actively construct knowledge and in which performing investigations and conducting experiments is central. To support learners in designing informative experiments we created a scaffold, the Experiment Design Tool (EDT), that provided learners with a step-by-step structure to select variables and to assign values to these variables, together with offering built-in heuristics for experiment design. To further structure the students’ approach, the EDT was offered within a set of detailed research questions which again were grouped under a set of broader research questions. Learning results for learners who worked with the EDT were compared to results for learners in two control conditions. In the first control condition, learners received only the detailed research questions and not the EDT; in the second control condition, learners received only the limited set of general research questions. In all conditions, learners conducted their experiments in an online learning environment about the physics topic of Archimedes’ principle. Conceptual knowledge was measured before and after the intervention using parallel forms of a knowledge test. Overall results showed significant learning gains in all three conditions, but no significant differences between conditions. However, learners who started with low prior knowledge showed a significantly higher learning gain in the EDT condition than in the two control conditions. This result indicates that the effect of providing learners with scaffolds does not follow a “one-size-fits-all” principle, but may depend on specific learner characteristics, such as prior knowledge. 相似文献

Floorplan, clock network and power plan are crucial steps in deep sub-micron system-on-chip design. A novel di- agonal floorplan is integrated to enhance the data sharing between different cores in system-on-chip. Custom clock network con- taining hand-adjusted buffers and variable routing rules is constructed to realize balanced synchronization. Effective power plan considering both IR drop and electromigration achieves high utilization and maintains power integrity in our MediaSoC. Using such methods, deep sub-micron design challenges are managed under a fast prototyping methodology, which greatly shortens the design cycle. 相似文献

Product design is the convergence point for engineering and design thinking and practices. Until recently, product design has been taught either as a component of mechanical engineering or as a subject within design schools but increasingly there is global recognition of the need for greater synergies between industrial design and engineering training. Product design engineering (PDE) is a new interdisciplinary programme combining the strengths of the industrial design and engineering. This paper examines the emergence of PDE in an environment of critique of conventional engineering education and exemplifies the current spread of programmes endorsing a hybrid programme of design and engineering skills. The paper exemplifies PDE with the analysis of the programme offered at Swinburne University of Technology (Australia), showing how the teaching of ‘designerly’ thinking to engineers produces a new graduate particularly suited to the current and future environment of produce design practice. The paper concludes with reflections on the significance of this innovative curriculum model for the field of product design and for engineering design in general. 相似文献

Instructional Design Knowledge (IDK) can inform technology integration decisions and Technology Pedagogy and Content Knowledge (TPACK) can help instructional design processes. As a means to understand how teachers may draw from their TPACK and IDK as they design instructions and develop technology-enhanced learning activities, we examined the final projects of two groups of teachers enrolled in graduate-level instructional design and technology courses. By using both content and social network analysis methods, we identified the IDK and TPACK components exemplified in teachers’ projects. While the content analysis revealed differences between the two groups, some findings were common across the courses such as teachers minimally connecting technology to their content areas, exhibiting limited knowledge on learning needs, and having difficulties in engaging in design thinking processes. Furthermore, the social network analysis identified various communities of the knowledge components, highlighting when teachers tended to use their IDK and TPACK as they planned technology-enhanced learning activities and were engaged in instructional design respectively.

INTRODUCTION 3D CAD systems for the feature-based B-rep solid models (Choi et al., 2002; Kim et al., 2003; 2005; Koo and Lee, 2002; Lee et al., 2004; Lee, 2005a) are becoming more suitable for CAD when compared with the conventional polygon-based mul- tiresolution modelling in computer graphics (Cignoni et al., 1998; Schr?der et al., 1992). As illustrated in Fig.1b, the object of the feature-based multiresolution modelling is a solid model where the suppressed ob- jects are form feat… 相似文献

Teacher involvement in curriculum design: need for support to enhance teachers’ design expertise 总被引：1，自引：1，他引：0
Teacher involvement in curriculum design has a long tradition. However, although it fosters implementation of curriculum reforms, teachers encounter various problems while designing related to conditions set for the design process, and lack the knowledge and skills needed to enact collaborative design processes. Providing support to enhance teachers’ design expertise is essential, since most teachers are novice designers. However, little is known about the nature of the support offered to improve teachers’ design expertise. In this explorative study, six teachers and six facilitators offering support reflected on an enacted design process, the problems they experienced and the support offered. The findings indicate three gaps in teachers’ design expertise related to three domains (1) curriculum design expertise, (2) pedagogical content knowledge and (3) curricular consistency expertise. The outcomes of this study illustrate the importance of supporting teacher designers during the design process and enhancing teachers’ design expertise. By offering (tailored) support to teachers, the enacted design process and the quality of the design materials are expected to improve. 相似文献

INTRODUCTION Most nonlinear optimization methods assumethat objective function variables are continuous.However, many practical engineering designproblems frequently encounter discrete variables aswell as continuous variables. Discrete variables areused in many ways such as the representation of theset of standard sized components, the decision onthe number of identical parts or the choice betweendifferent design options. For example, the numberof the teeth of a gear must be chosen … 相似文献

As creativity is likely to become a crucial aspect of living in the future, it is important for educators to teach students to think creatively when solving constantly evolving and increasingly complex problems. Supported by the idea that creativity can be taught and learnt, elements of creativity are now embedded in secondary school education. Among all school subjects, design and technology (D&T) is one of the best examples for fostering and cultivating students?? creativity, as the subject offers creative activities that enable students to realize their ideas in the context of the real world. This paper analyzes the creative elements in the D&T curriculum in Hong Kong as seen in the exemplar projects on the Education Bureau website. Some problems and difficulties encountered in fostering creativity in the context of Hong Kong are identified, based on the current teaching environment. The paper also draws attention to East Asian beliefs and implicit theories, which greatly influence teachers?? underlying assumptions about learning and teaching, and at the same time notes that these beliefs may be detrimental to the development of creativity among students. The paper then identifies the problems and inadequacies in fostering creativity in design at the secondary school level and expects to raise awareness of the importance of creativity in D&T. 相似文献

Using texture synthesis in fractal pattern design 总被引：2，自引：0，他引：2
INTRODUCTIONIn the last two decades, research on fractal ge-ometry has received much attention for its theoretical significance and practical applications. Pattern design based on fractal geometry is an important application area of fractal techniques in the textile industry (Wang, 2003). Computer aided pattern design involves the de-sign of textures and colors in the pattern. The source of textures is rich. All kinds of objects and scenery including man-made abstract objects can be used… 相似文献
