了解系统如何以及为什么随着时间的推移而变化是理解和导航我们的世界的有力方法。通过对这些系统进行建模，学习者有机会考虑自己的行为如何影响世界，并对未来做出预测和建议。但通常情况下，变化的概念既复杂又强大--人口水平、全球气温或经济趋势都是由多个事件和行为体驱动的，但只能用几个数量来衡量。在本文中，我们讨论的动机，设计和试点用户研究的DeltaTick，扩展NetLogo（Wilensky，1999年）基于代理的建模环境，使学生能够轻松地建立和分析复杂的模型定量变化在特定的现实世界的领域。为了做到这一点，他们根据基于代理行为的单元来构建模型，而不是基于微积分或系统动力学模型的典型的基于速率的单元。然后，他们可以探索这些模型，特别注意结果的定量趋势图，为他们提供多种机会，将他们的行为模型与典型的基于方程的表示进行连接和比较。
Understanding how and why systems change over time is a powerful way to make sense of and navigate our world. By modeling those systems, learners have the opportunity to consider how their own actions influence the world, and to make predictions and recommendations for the future. But often, the very notion of change is as complex as it is powerful - population levels, global temperatures, or economic trends are all driven by multiple events and actors, but measured in terms of only a few quantities. In this paper, we discuss the motivation, design, and pilot user studies of DeltaTick, an extension to the NetLogo (Wilensky, 1999) agent-based modeling environment that allows students to easily build and analyze sophisticated models of quantitative change within specific real-world domains. To do so, they construct models in terms of agent behavior-based units, rather than the rate-based units typical of calculus-based or system dynamics models. They can then explore those models with specific attention to plots of quantitative trends that result, providing multiple opportunities for them to connect and compare their behavioral models to typical equation-based representations.
