This study investigates cohesion in the spoken English discourse of thirty Arabs from three proficiency levels: superior, advanced, and intermediate. Two models were applied to the analysis. Halliday and Hasan's taxonomy was used to investigate local cohesion, or cohesion withinn turns; and Schiffrin's discourse markers approach was used to investigate global cohesion, or cohesion between turns. An ANOVA determined that the differences between the means of the three groups were significant for global cohesion and insignificant for local cohesion. The results suggest that the ability to use global cohesive ties increases with proficiency. This ability is manifested by the use of a variety of markers to achieve different communicative goals that include reorientation to information, coordination of ideas, and modification of previous responses.

The purpose of this dissertation was to investigate the perceptions of preservice teachers toward native and nonnative English speaking (NES and NNES) graduate teaching assistants (GTAs) in English as a second language (ESL) methodology and/or ESL assessment courses at a Southwestern U.S. university. This study also investigated the perceptions of NES and NNES GTAs toward preservice teachers. This study explored the issue of whether preservice teachers are prepared to accept and validate diversity among their instructors which in turn should make them sensitive to diverse learners they will encounter in their future teaching. In the first part of the study, a total of 262 preservice teachers were surveyed. The survey data were collected in spring 2007 and fall 2008. Of the 262 preservice teachers, 20 participated in focus group discussions to provide further insight on their views of NES and NNES GTAs. In the second part of the study, four GTAs participated in a longitudinal study by writing online blog entries after any encounters (positive or negative) they had with their students inside and outside the classroom. The blogs reflected the GTAs? immediate reactions after their classes. In addition, semi-structured interviews were conducted with the GTAs. Findings of the first study revealed that preservice teacher perceived NES and NNES GTAs differently. Preservice teachers put a lot of emphasis on the intelligibility of the NNES GTAs. The preservice teachers were ?tolerant? if their NNES spoke English ?clearly?. However, there were some preservice teachers who were dissatisfied with their NNES GTAs due to their possessing a non-mainstream language. Findings of the second study revealed that NNES GTAs faced major challenges in their effort to be recognized as legitimate and competent instructors. Although the GTAs had vastly different personal backgrounds, perceptions, and identities as instructors, common themes or issues emerged from the data: (1) teaching is complex (linguistic, cultural, and racial issues are involved); (2) beliefs about teaching can change; (3) challenges are faced as an ?outsider? instructor; and (4) teaching provides experiences of joy. The study has implications for teacher education programs and training programs offered for international graduate students by universities.

The purpose of this study was to examine the implicit language attitudes of college-level instructors toward accented English and the effect of gender, teaching experience, and home language background on those attitudes. The auditory multifactor Implicit Association Test (IAT) was used to measure the implicit attitudes toward Standard, Chinese, Hispanic, and Korean accented English. For the current study, audio stimuli were embedded into the multifactor IAT, which became available for the first time in 2014. The auditory multifactor IAT generated implicit preference scores of six pairs of accented English: Standard vs. Chinese, Standard vs. Hispanic, Standard vs. Korean, Chinese vs. Hispanic, Chinese vs. Korean, and Hispanic vs. Korean accented English. Participants (N = 93) included college instructors at an urban university in Florida. Statistical analysis results suggested that college instructors in this study exhibited some bias towards speakers of Hispanic-accented English, but no bias toward the other five. However, analysis of the frequency distributions of the responses showed bi-polar accent biases did exist. It was possible that the similar numbers for the polar opposites balanced each other in the statistical results of no bias. Gender and home language background had no effect on implicit preference scores. The years of teaching experience had significant effect in Hispanic- vs. Korean-accented English, but not in the other five accented language pairs. However, close examination of the beta coefficient per year indicated that the relationship was weak even though the effect was significant. Faculty, administrators, and students could use test results as a topic of discussion in faculty development, teaching assistant training, student services, and diversity training in higher education institutions. The discussions might help awareness of hidden-yet-present accent bias and prevent potential prejudice toward other accented English speakers. The administrators need to be aware that preferences do exist toward accented English speakers. These preferences--or biases--toward an accent may be important in selecting instructors.

This study explored the impact of the importation of expatriate English teachers on the morale of the Malaysian English teachers and attempted to identify the perceptions of Malaysian English teachers, expatriate native English-speaking teachers (NESTs), and expatriate nonnative English-speaking teachers (nonNESTs) regarding the practices that are prevalent in Malaysia in areas such as hiring, remuneration, and benefits. An initial questionnaire was completed by the participants to ensure that they fit the target demographic profiled. Then, a semi-structured interview was conducted as a follow-up to the participants' open-ended responses in the second part of the questionnaire. Completed questionnaires were gathered from ten participants, and two semi-structured interviews were conducted with an expatriate NEST and a Malaysian nonNEST respectively. Descriptive statistics were used to analyze responses to the seven-point Likert-scale statements. In addition, this study took a qualitative approach in analyzing the core themes of the responses in the semi-structured interview and the questionnaire. Examining individual survey items and interviews revealed that there is a large discrepancy in wages between NESTs and nonNESTs in Malaysia, and this contributes to the unhappiness and low morale of Malaysian English teachers. In addition, the presence of expatriate NESTs causes Malaysian nonNESTs to have low self-esteem as they compare themselves to their native counterparts. This study also revealed that participants felt that the importation of expatriate NESTs had no significant impact on improving the language proficiency of students. Owing to the perceived failure to deliver desired results, the majority of the participants agreed that hiring qualified and experienced English teachers (not on the basis of one's race or first language) is paramount in improving the language proficiency of Malaysian students. The analysis of the data collected resulted in recommendations for a more in-depth study of the impact of the importation of expatriate NESTs/nonNESTs to the morale of Malaysian nonNESTs and the improvement of the language proficiency of Malaysian students. Also, the contributing factors for the decline of the English proficiency of Malaysian students should be thoroughly evaluated so as to affect change.
