Abstract: Techniques for teaching geometric proof problems are described. According to one approach, the geometric proof application displays a geometric proof problem and a set of connectable nodes in an initial arrangement. A user then rearranges the set of connectable nodes and connects them using one-way connections to generate a solution. The geometric proof problem is solved if the user-generated solution indicates the correct logical ordering of the set of connectable nodes as determined by the geometric proof application.

Abstract: Techniques are described for an automated grammar teaching system that displays sentences and allows a user to identify subject-verb agreement errors within the sentences, if any. The sentences may be presented as single sentences or as part of a paragraph. The user may be asked to determine whether the sentences are correct or incorrect, to identify the locations of verbs that should agree with a subject of the sentence, to identify the core noun that determines whether the subject is singular or plural, and to provide a new verb that agrees with the subject. To guide the user, user responses may trigger the display of remediation information, which may include identifying one or more grammar elements of the sentences that are relevant to identifying the subject-verb agreement errors. New sentences in the teaching system may be selected based on historical data maintained for the user.

Abstract translation: 描述了用于显示句子并允许用户识别句子内的主题 - 动词协议错误（如果有的话）的自动语法教学系统的技术。 句子可以单句或段落的一部分来表示。 可能要求用户确定句子是正确还是不正确，以识别应该与句子主体一致的动词的位置，以确定确定对象是单数还是复数的核心名词，并提供一个 与该主题相符的新动词。 为了引导用户，用户响应可以触发修复信息的显示，其可以包括识别与识别主体 - 动词协议错误相关的句子中的一个或多个语法元素。 可以基于为用户维护的历史数据来选择教学系统中的新句子。
