Undergraduate students fail to objectively self-assess grammar skills of English as a second language but mastering English grammar autonomously can assist. The article aims to describe and assess the Moodle plugin that offers undergraduate students individual learning paths in studying English grammar. An experiment with 3953 students was conducted at Peoples’ Friendship University of Russia in two academic years: 2017–2018, 2018–2019. The Moodle plugin “RUDN CourseAssist” facilitated the English grammar study. The students subjectively stated their English language proficiency level and set academic goals in a self-assessment learner profile. The diagnostic stage of the experiment identified premises that provided individual learning paths in studying English grammar: automatic level detection (A1, B1, B2) and learning styles (active learners – 59.9%, sensing – 49.7%, visual – 81%, global – 49.7%). At the test assessment stage, 491 students demonstrated a steady rise in doing grammar exercises correctly, and performed more objective self-assessment of the level. At the plugin assessment stage, the Pearson correlation coefficient and the students’ feedback in questionnaires and interviews proved that the plugin is flexible, scalable, user-friendly, and applicable. The state-of-the-art plugin to be customised for other languages is effective in providing students with individual learning paths to improve English grammar skills.

大学生无法客观地自我评估英语作为第二语言的语法技能，但自主掌握英语语法可以提供帮助。本文旨在描述和评估Moodle插件，该插件为大学生提供了学习英语语法的个人学习途径。在两个学年中，俄罗斯人民友谊大学对3953名学生进行了实验：2017–2018、2018–2019。Moodle插件“ RUDN CourseAssist”促进了英语语法学习。学生主观地陈述了他们的英语水平，并在自我评估学习者的个人资料中设定了学术目标。实验的诊断阶段确定了前提条件，这些前提条件为学习英语语法提供了单独的学习途径：自动水平检测（A1，B1，B2）和学习方式（积极学习者– 59.9％，感官– 49.7％，视觉– 81％，全球– 49.7％）。在测试评估阶段，有491名学生表现出正确地进行语法练习的稳步提高，并对该水平进行了更客观的自我评估。在插件评估阶段，Pearson相关系数以及学生在问卷和访谈中的反馈证明插件是灵活，可扩展，用户友好和适用的。为其他语言定制的最先进的插件可以有效地为学生提供个性化的学习途径，以提高英语语法技能。在插件评估阶段，Pearson相关系数以及学生在问卷和访谈中的反馈证明插件是灵活，可伸缩，用户友好和适用的。为其他语言定制的最新插件可以有效地为学生提供个性化的学习途径，以提高英语语法技能。在插件评估阶段，Pearson相关系数以及学生在问卷和访谈中的反馈证明插件是灵活，可扩展，用户友好和适用的。为其他语言定制的最新插件可以有效地为学生提供个性化的学习途径，以提高英语语法技能。
