Why is there not any mention or examples of complex fractions in Technical material or the code book? How are we expected to accurately transcribe anything? The NBA staff who put together this material makes if very difficult for transcribers to do their work. I don't have the time to logon, write a question and then wait for an answer for every little thing; deadlines are critical. The code book should be a definitive tool for all types of problems, from very easy (which are the predominant problems shown) to advanced math. Easy problems do not offer any suggestions in most cases for advanced math problems. Transcribers are told to to include TNs for explanation to the student, but NBA does not consider the same for transcribers. We are given partial info with confusing rules scattered thruout the code to "build" a problem when a simple example would bring all this info together.
I agree that the examples given in Rules of UEB and Guidelines for Technical Material can leave us transcribers feeling frustrated.
No one at the National Braille Association is in a position to explain why the codebooks are they way they are, because NBA is not an organization that creates or maintains any codebooks. The Braille Authority of North America and the International Council on English Braille are the decision-making bodies for braille codes that are used in the United States and Canada. NBA is a training organization.
For what it is worth, the last example on page 32 of the Guidelines for Technical Material does include complex fractions.
In addition, we volunteers at NBA are open to members' suggestions of topics to be covered in future trainings and professional articles.
Thank you for your input and for the hard work you are doing in the braille field.
