【中文说明】用于设计或审核单节课与培训活动，检查教学目标、活动时长、练习和评估是否匹配，并发现超时或缺少开场收尾的问题。提供主题、学生年龄、基础、总课时和已有教案，让AI生成时间分配清晰且可衡量学习成果的方案。 Designs and reviews single-lesson plans for teachers, tutors, and trainers: measurable objectives, a timed activity sequence that fits the period, and a tested checker that flags overruns, objectives without practice or assessment, long lectures for the age group, and missing openings or closures.
