The Effectiveness of Online Courses in Building Nemeth Code Within UEB Contexts Skills and Increasing Knowledge of Strategies to Support Prekindergarten Through Eighth-Grade Students in Their Mathematics Learning.

Introduction: Professional development can assist individuals in learning a variety of new skills and refining their teaching practice. The purpose of this study was to explore the effectiveness of asynchronous online courses designed to assist individuals in building their Nemeth Code within Unified English Braille (UEB) Contexts skills and strategies for teaching the code to prekindergarten through eighth-grade students. Methods: Four teachers of students with visual impairments designed five asynchronous online courses. The courses provided multiple opportunities for participants to actively complete course content as well as learn about strategies and resources for teaching the Nemeth Code within UEB Contexts to children and youths. Each course included an initial survey, pretest, seven self-paced lessons, and posttest. Participants were also invited to complete a follow-up survey. Results: Between spring 2020 and spring 2023, 452 participants completed between 1 and 5 of the courses for a total of 620 courses completed. Almost all completers (n = 598) scored higher on the posttest. Of the 227 individuals who completed the follow-up survey, 223 reported that what they learned in the course had positively impacted how they support or will support students who read braille in their math classes. Discussion: Effective professional development goes beyond learning. When individuals actively consume content and reflect upon their learning, their professional practice is transformed. Implications for Practitioners: Well-designed asynchronous instructional modules allow professionals to increase their knowledge and skills. Opportunities to practice skills and check one's work, access to instructional videos, and the availability of downloadable slides and resources are helpful to professionals. [ABSTRACT FROM AUTHOR]
