This paper describes an in-house developed language tool called VPerl used in developing a 250 MHz 32-bit high-performance low power embedded CPU core. The authors showed that use of this tool can compress the Verilog code by more than a factor of 5, increase the efficiency of the front-end design, reduce the bug rate significantly. This tool can be used to enhance the reusability of an intellectual property model, and facilitate porting design for different platforms. 相似文献

This paper describes an integrated authoring environment, AIDA (Ambiente Integrado de Desenvolvimento de Aplicações educacionais). It is an open tool, giving the author a high degree of freedom both in package characteristics and design methodologies used. This environment integrates several modules. The core of the design module is a prototyping tool, allowing the creation of evolutionary prototypes. These prototypes can include several types of multimedia components and can be used as part of the final package. The AIDA environment also includes other options that support evaluation, learning materials re-use, communication between authoring team members and translation and cultural adaptation of packages to work in different environments. An experimental version of this authoring environment was implemented and the results of its evaluation are encouraging. In this paper we also present an example of a package created with the AIDA authoring environment. 相似文献

In this paper we present three cases of instructional design that illustrates both horizontal didactising, the activity of
using already established principles to design instruction, and vertical didactising the activity of developing new tools
and principles for instructional design. The first case illustrates horizontal didactising by elaborating how the constructs
chains of signification and models were used to design an instructional sequence involving linear growth. The second and third
cases illustrate vertical didactising by developing argumentation analyses and generative listening, respectively, as instructional
design tools. In the second case, argumentation analyses emerge as a tool that other designers can use to anticipate the quality
of conversations that can occur as students engage in tasks prior to implementing the instructional sequence. The third case
develops the notion of generative listening as a conceptual tool within the context of designing differential equations instruction
to gain insights into what are, for students, experientially-real starting points that are mathematical in nature and to provide
inspirations for revisions to instructional sequences.

Abstract This paper and the accompanying tool are intended to complement existing supports for conducting power analysis tools by offering a tool based on the framework of Minimum Detectable Effect Sizes (MDES) formulae that can be used in determining sample size requirements and in estimating minimum detectable effect sizes for a range of individual- and group-random assignment design studies and for common quasi-experimental design studies. The paper and accompanying tool cover computation of minimum detectable effect sizes under the following study designs: individual random assignment designs, hierarchical random assignment designs (2-4 levels), block random assignment designs (2-4 levels), regression discontinuity designs (6 types), and short interrupted time-series designs. In each case, the discussion and accompanying tool consider the key factors associated with statistical power and minimum detectable effect sizes, including the level at which treatment occurs and the statistical models (e.g., fixed effect and random effect) used in the analysis. The tool also includes a module that estimates for one and two level random assignment design studies the minimum sample sizes required in order for studies to attain user-defined minimum detectable effect sizes. 相似文献

The Advanced Instructional Design Advisor is an Air Force project which involves the development and testing of automated instructional design guidance for use by Air Force technical training specialists in the development of computer-based training (CBT). This paper discusses the particular structure of an experimental instructional design advisor and how it has and will be used as a research platform to guide future efforts in automating instructional design. The experimental system described makes use of automated instructional strategies which can be systematically altered along a number of dimensions (e.g., amount of learner control, use of qualitative feedback during practice, etc.). Such a tool is essential to conduct research in this area, and has the added benefit of facilitating the rapid prototyping of CBT. 相似文献

The development of university wide graduate attributes has become an important mechanism for setting generic learning outcomes across higher education institutions. Many universities around the world have developed sets of graduate attributes that they aim to develop through degree programs. Sustainability related attributes have been included in numerous university attribute statements, however, little research exists on methods that can be used to capture data on the application and use of these attributes by graduates. This paper evaluates an assessment tool, based on a scenario/vignette question design, which can be used to capture data on graduate attributes in context and has the potential to be used across a large graduate population which would enable comparative research of learning outcomes to be undertaken. An evaluation of the usefulness of the scenario/vignette design will be presented based on a pilot of the question design with a sample of RMIT University graduates. The results of the pilot show that scenario/vignettes address some of the limitations of existing self-assessment methods and represent a novel way to collect data on graduate sustainability attributes post-degree completion. 相似文献

CADMOS is a graphical learning design (LD) authoring tool that helps a teacher design a unit of learning in two layers: (i) the conceptual layer, which seems like a concept map and contains the learning activities with their associated learning resources and (ii) the flow layer, which contains the orchestration of these activities. One of CADMOS’ main innovative features is that it can bridge the gap between the design of a unit of learning and its enactment into Moodle. This paper presents how one can create a LD using CADMOS and deploy it into Moodle. Also, the paper shows the findings from a case study which was organized in order to evaluate the usability of the tool, its pedagogical flexibility and the usefulness of its innovative feature of deploying a LD into Moodle. CADMOS seems to be an easy-to-use tool, which offers guidance and flexibility during the design process. 相似文献

This paper argues that Internet‐based instruction should not be only perceived as a cognitive tool or a metacognitive tool; rather, it can be perceived and used as an epistemological tool. When the Internet is used as an epistemological tool for instruction, learners are encouraged to evaluate the merits of information and knowledge acquired from Internet‐based environments, and to explore the nature of learning and knowledge construction. This paper further asserts that Internet‐based instruction is perceived as a way to help learners develop advanced epistemologies. On the other hand, developmentally advanced epistemological beliefs can facilitate the practice of Internet‐based instruction. 相似文献

This article addresses writing in higher education with the primary aim of conceptualizing writing as a mediational tool. The conceptual framework consists of three concepts: learning trajectories, mediation, and recontextualization. The article describes how writing can work as a mediational tool and suggests possible implications for higher education. An empirical study from the context of initial teacher education in Norway is used for the purpose of illustration. Writing activities can mediate learning in important ways. However, design elements that make students explore, contrast, and compare different meaning potentials and position themselves within disciplinary or professional discourse are crucial when considering the potential of writing as a mediational tool in higher education. 相似文献
