Interactive learning tools can facilitate the learning process and increase student engagement, especially tools such as computer programs that are designed for human-computer interaction. Thus, this paper aims to help students learn five different methods for solving nonlinear equations using an interactive learning tool designed with common principles such as feedback, visibility, affordance, consistency, and constraints. It also compares these methods by the number of iterations and time required to display the result. This study helps students learn these methods using interactive learning tools instead of relying on traditional teaching methods. The tool is implemented using the MATLAB app and is evaluated through usability testing with two groups of users that are categorized by their level of experience with root-finding. Users with no knowledge in root-finding confirmed that they understood the root-finding concept when interacting with the designed tool. The positive results of the user evaluation showed that the tool can be recommended to other users. 相似文献

Much of the behaviour of an interactive system is determined by its user population. This paper describes how assumptions
about the user can be brought into system models in order to reason about their behaviour. We describe a system model containing
reasonable assumptions about the user as being ‘cognitively plausible’. Before asserting the plausibility of a model however
we must first be able to make the assumptions made in that model inspectable.
There is a tension between the inspectability of user assumptions and the tractability of models; inspectable models tend
to not be very tractable and vice versa. We describe how we can get round this tension, by deriving tractable models from explicit user assumptions. The resulting
models may not of themselves be very inspectable to human-factors workers, but the process by which they are derived is inspectable.
Hence we claim that we can have both tractability and inspectability. We exemplify our claims using a simple cognitive model
and ‘Meeting Maker’, an interactive electronic diary system.

输送系统的UML建模、优化与实现 总被引:1,自引:0,他引:1
将面向对象方法引入输送系统的建模和分析过程,采用统一建模语言UML对系统的功能、对象结构、行为和活动以及实现方式等建立了一整套模型。UML模型可以采用面向对象语言快速实现,按照模块化结构,使用PLC编程语言也可实现面向对象编程。采用UML对输送系统进行分析可将系统实现的复杂性降低,有利于系统的分析和设计,系统的优化算法可以在此基础上进一步研究和实现。(以一个工程为实例,说明了相对于传统的顺控方案,以UML模型为基础的输送系统在开发和维护、扩充和代码重用等方面具有显著优势,UML在顺序控制系统中具有广阔的应用和研究前景。) 相似文献

Aerospace design is a complex task requiring access to large amounts of specialized information. Consequently, intelligent systems that support and amplify the abilities of human designers by capturing and presenting relevant information can profoundly affect the speed and reliability of design generation. This article describes research on supporting aerospace design by integrating a case-based design support framework with interactive tools for capturing expert design knowledge through concept mapping. In the integrated system, interactive concept mapping tools provide crucial functions for generating and examining design cases and navigating their hierarchical structure, while CBR techniques facilitate retrieval and aid interactive adaptation of designs. Our goal is both to provide a useful design aid and to develop general interactive techniques to facilitate case acquisition and adaptation. Experiments illuminate the performance of the system's context-sensitive retrieval during interactive case adaptation and the conditions under which it provides the most benefit. 相似文献
