非理性用户模型在虚拟实验中的构建与应用     

李宇佳  杨雪 《现代远程教育研究》2014,(2):107-112

随着虚拟实验在教学中的广泛应用,如何设计合乎人自然真实状态的虚拟实验成为研究者的努力方向。传统的虚拟实验设计一般以正常的、理性的操作情况为主要对象,缺乏对学习者在非正常情景和非理性心理因素下的认知和行为特性考虑,很容易导致操作出错,增加学习者的认知负荷。因此在虚拟实验设计过程中,需将用户的非理性因素融入其中,构建非理性用户模型指导设计过程。考虑到人的非理性主要表现在认知、情绪、行动各个阶段,虚拟实验的非理性用户模型应该包括认知模型、行动模型、出错模型和环境模型四个子模型。基于非理性用户模型,虚拟实验设计应注意满足学习者的视觉意向性,合理布局界面容量及结构,优化交互设计,重视虚拟实验系统的出错预防及矫正功能,提高虚拟实验的智能性。  相似文献

张向阳 《陕西国防工业职业技术学院学报》2006,(1)

ASP.NET是一种建立在通用语言基础上的Web开发技术,可以用于开发功能强大的Web应用程序。相对于传统的ASP而言,ASP.NET在开发效率、平台无关性、安全性等方面具有显著的优势。在当今的Web开发领域,ASP.NET已经成为应用非常广泛的技术之一。本文介绍了如何在ASP.NET页面中动态添加用户控件,以及如何控制动态控件的显示格式。  相似文献   

Teacher behavior, student interest and affective learning: putting theory to practice     

Keith Weber  Matthew Martin  Brian Patterson 《Journal of Applied Communication Research》2001,29(1):71-90

Students of Project Adapt (PA), an instructional program for at-risk middle school students in Brooklyn NY, have displayed startling improvement on cognitive outcome measures. Teacher given grades and standardized tests illuminate the progress students have made since entering the program. The current investigation attempts to analyze PA on students' affective responses in a pre/post-test experimental design. Upon entering PA, students completed measures of interest, affect, and their previous teachers' behavior (pre). These ratings were then compared to end of year ratings on the same instruments (post). Results indicate students' perceive PA teachers utilizing different behaviors than their previous teachers. Additionally, student affect and interest increased significantly. Results of this study have implications for both instructional researchers and educational practitioners.  相似文献

Examining the effect of user satisfaction on system usage and individual performance with business intelligence systems: An empirical study of Taiwan's electronics industry     

Chung-Kuang Hou 《International Journal of Information Management》2012

The advent of new information technology has radically changed the end-user computing environment over the past decade. To enhance their management decision-making capability, many organizations have made significant investments in business intelligence (BI) systems. The realization of business benefits from BI investments depends on supporting effective use of BI systems and satisfying their end user requirements. Even though a lot of attention has been paid to the decision-making benefits of BI systems in practice, there is still a limited amount of empirical research that explores the nature of end-user satisfaction with BI systems. End-user satisfaction and system usage have been recognized by many researchers as critical determinants of the success of information systems (IS). As an increasing number of companies have adopted BI systems, there is a need to understand their impact on an individual end-user's performance. In recent years, researchers have considered assessing individual performance effects from IS use as a key area of concern. Therefore, this study aims to empirically test a framework identifying the relationships between end-user computing satisfaction (EUCS), system usage, and individual performance. Data gathered from 330 end users of BI systems in the Taiwanese electronics industry were used to test the relationships proposed in the framework using the structural equation modeling approach. The results provide strong support for our model. Our results indicate that higher levels of EUCS can lead to increased BI system usage and improved individual performance, and that higher levels of BI system usage will lead to higher levels of individual performance. In addition, this study's findings, consistent with DeLone and McLean's IS success model, confirm that there exists a significant positive relationship between EUCS and system usage. Theoretical and practical implications of the findings are discussed.  相似文献
