This paper proposes a web-based application designed to help elementary school students who have difficulty learning online independently and also their parents who are currently having difficulty teaching their children to study at home online, especially at this time of difficulty with a pandemic outbreak like COVID-19; this time does not allow for physical meetings for the learning process in primary schools. In this paper, we only focus on mathematics because based on several other studies, it is very difficult and important to learn mathematics at the beginning of educational activities such as at the elementary school level. In this paper, the system is modeled using the Unified Modeling Language (UML) tool in the form of a use case diagram which is used to describe the proposed business process and uses class diagrams to describe the database model diagram. In this case, the class diagram is used to describe the data in the class diagram where each class refers to a table in the database. The web-based application user interface is shown at the end to show the communication between users and applications, where this web-based application is implemented using Personal Home Pages (PHP) as server programming and using MySQL to store database model designs. Moreover, for the Intelligent Tutoring System (ITS), content was created using the Cognitive Tutor Authoring Tools (CTAT) which is an authoring tool for learning mathematics created by Carnegie Mellon University. In the end, this web-based application is expected to be used and support teachers as a complement to online mathematics learning, especially during difficult times such as during the COVID-19 pandemic.

智能辅导系统：小学六年级数学学习

本文提出了一种基于网络的应用程序，旨在帮助在独立在线学习方面有困难的小学生以及目前在家教孩子在线学习有困难的父母，尤其是在像 COVID 这样的大流行爆发的困难时期-19; 这段时间不允许在小学的学习过程中进行物理会议。在本文中，我们只关注数学，因为基于其他几项研究，在小学阶段等教育活动开始时学习数学是非常困难和重要的。在本文中，该系统使用统一建模语言 (UML) 工具以用例图的形式建模，用例图用于描述提议的业务流程，并使用类图来描述数据库模型图。在这种情况下，类图用于描述类图中的数据，其中每个类引用数据库中的一个表。最后展示了基于 Web 的应用程序用户界面，以显示用户和应用程序之间的通信，该基于 Web 的应用程序使用个人主页 (PHP) 作为服务器编程并使用 MySQL 存储数据库模型设计来实现。此外，对于智能辅导系统 (ITS)，内容是使用认知辅导创作工具 (CTAT) 创建的，这是一种由卡内基梅隆大学创建的用于学习数学的创作工具。到底，
