the need for more additive models of bilingual education, as opposed to subtractive or transitional models of education, which are designed to shift the learner away from the native language for the goal of complete use and reliance of the majority language. For deaf children, subtractive models of bilingual education, combined with the lack of foundation of a native language, typically result in language deprivation and delay in cognitive development. In comparison, the aim the maintenance model, an additive model is "to support the development of the native language while also fostering acquisition and use of the majority language." This model is embedded in a bimodal, bilingual education and may include "comparative and integrative pedagogic strategies such as translation, fingerspelling, and chaining/sandwiching strategies." Simultaneous communication, or SimCom, which is a method of signing that represents English in its structure and elements, typically following English word order but still using one sign per word. However, research has shown this method of communication is not ideal for bilingual language learning. In a study about bimodal bilingual teachers and students' vocabulary levels, the results revealed a "slower speech rate, lower lexical richness, and lower syntactic complexity in the SimCom [teaching] condition compared with the speech-only condition." These findings suggest that "the [teachers'] production of the less dominant language (ASL) during SimCom entails inhibition of the dominant [spoken English] language relative to the speech-only condition." This study also acknowledges that SimCom is a "complex communication unit that cannot be reduced to the combination of two languages." Methodologies, strategies and support in bimodal bilingual education, as well as the language background and linguistic capital of bimodal bilingual educators are key aspects to the achievements of language competence of bimodal bilingual learners. Sign–print bilingualism The written forms of language can be considered another modality. Sign languages do not have widely accepted written forms, so deaf individuals learn to read and write an oral language. This is known as sign–print bilingualism—a deaf individual has fluency in (at least) one sign language as their primary language and has literacy skills in the written form of (at least) one oral language, without access to other resources of the oral language that are gained through auditory stimuli. Orthographic systems employ the morphology, syntax, lexical choices, and often phonetic representation of their target language in at least superficial ways; one must learn these new features of the target language in order
