Introduction: This study explored the impact of synchronous professional development regarding Nemeth Code Within Unified English Braille (UEB) Contexts on the knowledge and skills of 17 teachers of students with visual impairments. Methods: Participants attended the professional development sessions in June 2022 and submitted a pretest, posttest, final assignment, and posttraining survey. Results: Sixteen out of 17 participants scored higher on their posttest with a mean difference of 5.53. None of the participants submitted an error-free assignment. Total numbers of errors ranged from 8 to 60, and the categories with the highest percentage of errors were formatting, use of opening and terminating switch indicators, and Nemeth Code symbols. Discussion: In order to successfully progress in the general education curriculum, students who read braille must have access to timely, accurately prepared materials in all content areas including mathematics. Direct examination of the final assignment submitted by the 17 participants revealed similar error patterns to previous research. In addition, some of the participants struggled to correctly use Nemeth Code switch indicators. Implications for Practitioners: Teachers of students with visual impairments should continue to build their skills for Nemeth Code within UEB Contexts. Additional resources and professional development are urgently needed.

在线同步专业发展，支持视觉障碍学生的教师在统一英语盲文环境中学习 Nemeth 代码

简介：本研究探讨了统一英语盲文 (UEB) 背景下 Nemeth 代码的同步专业发展对 17 名视力障碍学生教师的知识和技能的影响。方法：参与者参加了 2022 年 6 月的专业发展课程，并提交了预测试、后测试、最终作业和培训后调查。结果：17 名参与者中有 16 名在后测中得分较高，平均差异为 5.53。没有一个参与者提交了无错误的作业。错误总数从 8 到 60 不等，错误百分比最高的类别是格式、打开和终止开关指示器的使用以及 Nemeth 代码符号。讨论：为了在普通教育课程中取得成功，阅读盲文的学生必须能够及时、准确地获取包括数学在内的所有内容领域的材料。对 17 名参与者提交的最终作业的直接检查揭示了与之前研究类似的错误模式。此外，一些参与者很难正确使用 Nemeth Code 开关指示器。对从业者的启示：视力障碍学生的教师应继续在 UEB 背景下培养 Nemeth 代码技能。迫切需要额外的资源和专业发展。
