Background: Currently, the majority of learners within the South African education system speak English as an additional language. Many of these children are therefore learning the language of instruction through the language of instruction. Of particular concern for speech-language therapists (SLTs) are those children who have language impairment. In addition, it is important for SLTs to be able to distinguish between the learners who have language impairment, and those who are merely in the process of acquiring English. Additionally, the identification of language impairment among learners who speak English as an additional language is difficult as there are no overt manifestations of language learning difficulties, and, unfortunately, these learners are easily over-looked during the pre-school and school-age years. Furthermore, specifically within the South African context, there are limited tools available that can be used to screen for, and/or diagnose language impairment among EAL learners. Purpose: The main aim of this study was to explore the use of sentence repetition as a screening tool for the identification of language impairment in learners who speak English as an additional language. Method: The research design of this study was non-experimental, quantitative, descriptive and cross-sectional in nature, with comparative and correlational components. One hundred and seven grade 2 EAL learners from a mainstream school in Gauteng participated in the study. The learners were evaluated on two sentence repetition tests; the Redmond (2005) Sentence Repetition Test and the Recalling Sentences subtest from the Clinical Evaluation of Language Fundamentals-4 (CELF-4) (Semel, Wiig & Secord, 2003). The learners were also evaluated on the Gray Oral Reading Test-4 (GORT-4) (Wiederholt & Bryant, 2001). The results obtained from these measures were correlated in order to determine the internal validity of the two sentence repetition measures, as well as to investigate the extent to which sentence repetition can be used to predict academic literacy. Learners who were identified as being at-risk for language impairment, namely those who fell 1 standard deviation (SD) below the peer group mean on the Redmond (2005) Sentence Repetition test were further evaluated using the Diagnostic Evaluation of Language Variation-Criterion Referenced edition (DELV-CR) (Seymour, Roeper & de Villiers, 2003), to diagnose language impairment, avoid misdiagnosis, and describe the manifestations of language impairment in the second language. Results and Implications: The results of the Redmond (2005) Sentence Repetition test proved to be a valid measure to identify learners who were at-risk for language impairment, provided that the peer group mean was used as a standard of comparison. Twelve of the 107 (11.2%) learners from the study were identified as being at-risk for language impairment. However, after analysis of the results and using a peer group mean from Jordaan’s (2011) study, only 9/12 (7.5%) of the participants were diagnosed with language impairment. This finding highlights the fact that EAL learners are often over-identified as having language impairment and further assessment is necessary to minimise the risk of misdiagnosis of language impairment. The findings from the DELV-CR (Seymour, Roeper & de Villiers, v 2003), in terms of the manifestations of language impairment in the second language, were consistent with the EAL language impaired learners from Jordaan’s (2011) study, as well as the literature. This finding indicates that sentence repetition is a valid screening tool for the identification of language impairment in EAL learners. Furthermore, 11 of the 12 of the at-risk learners scored below the peer group mean on the reading comprehension measure. Thus, it is evident that, in addition to not being able to use language effectively for academic purposes, most children with language impairment are further disadvantaged by poor reading comprehension skills. An implication for future research would be to explore whether the development of a sentence repetition measure in an African language (e.g. Zulu) would yield similar results as the current study. In this way, EAL learners could be identified in their home language. A secondary finding of the current study was that the grade 2 educators were not able to identify learners who required additional language support within the classroom. This finding has implications for the role of SLTs in mainstream education and the need to support educators in their ability to identify learners with SLI and whose academic language development is not on par with that of their peers.

This study investigated the difficulty order of 38 grammar structures obtained from an analysis of multiple-choice items using a Rasch analysis. The order was compared with the order predicted by processability theory and the order in which the structures appear in junior and senior high school textbooks in Japan. Because processability theory is based on natural speech data, a sentence repetition test was also conducted in order to compare the result with the order obtained from the multiple-choice tests and the order predicted by processability theory. The participants were 872 Japanese university students, whose TOEIC scores ranged from 200 to 875. The difficulty order of the 38 structures was displayed according to their Rasch difficulty estimates: The most difficult structure was subjunctive and the easiest one was present perfect with since in the sentence. The order was not in accord with the order predicted by processability theory, and the difficulty order derived from the sentence repetition test was not accounted for by processability theory either. In other words, the results suggest that processability theory only accounts for natural speech data, and not elicited data. Although the order derived from the repetition test differed from the order derived from the written tests, they correlated strongly when the repetition test used ungrammatical sentences. This study tentatively concluded that the students could have used their implicit knowledge when answering the written tests, but it is also possible that students used their explicit knowledge when correcting ungrammatical sentences in the repetition test. The difficulty order of grammatical structures derived from this study was not in accord with the order in which the structures appear in junior and senior high school textbooks in Japan. Their correlation was extremely low, which suggests that there is no empirical basis for textbook makers'/writers' policy regarding the ordering of grammar items. This study also demonstrated the difficulty of writing items testing the knowledge of the same grammar point that show similar Rasch difficulty estimates. Even though the vocabulary and the sentence positions were carefully controlled and the two items looked parallel to teachers, they often displayed very different difficulty estimates. A questionnaire was administered concerning such items, and the students' responses suggested that they seemed to look at the items differently than teachers and what they notice and how they interpret what they notice strongly influences item difficulty. Teachers or test-writers should be aware that it is difficult to write items that produce similar difficulty estimates and their own intuition or experience might not be the best guide for writing effective grammar test items. It is recommended to pilot test items to get statistical information about item functioning and qualitative data from students using a think-aloud protocol, interviews, or a questionnaire. / CITE/Language Arts

The thesis reports on specific language impairment (SLI). First part of the thesis summarizes first the current theoretical knowledge about this issue. It reviews terminology, classification, etiology, symptoms, diagnostic, therapy and association SLI with developmental dyslexia. The thesis then refers about search for diagnostic markers of SLI in pre-school age. The empirical part of the thesis summarizes the research conducted. Three groups of children were compared- 19 children with SLI, 19 peers without SLI (AC) and 19 younger language- matched children (LC). Four diagnostic methods were used - picture vocabulary test, number recall, sentence repetition and non-word recall. In all tests children with SLI performed poorly than AC-group and in some of them also poorly than LC-group. Limitation in sentence repetition and non-word recall, omission of prepositions and clitics and also omission of verbs or using of incomplete infinitive forms in sentences were detected as possible relevant diagnostic markers.

Testing oral proficiency is an important, but often neglected part of the foreign language classroom. Currently accepted methods in testing oral proficiency are timely and expensive. Some work has been done to test and implement new assessment methods, but have focused primarily on English or Spanish (Graham et al. 2008). In this thesis, I demonstrate that the processes established for English and Spanish elicited imitation (EI) testing are relevant to French EI testing. First, I document the development, implementation and evaluation of an EI test to assess French oral proficiency. I also detail the incorporation of the use of automatic speech recognition to score French EI items. Last, I substantiate with statistical analyses that carefully engineered, automatically scored French EI items correlate to a high degree with French OPI scores.
