English Language Teaching (ELT) can be considered an ideological enterprise especially at a time when the spread of English and the ELT profession are related to post-colonial and capitalist interests (Phillipson, 1992, 1997, 2000, 2006; Pennycook, 1994, 1997a; Canagarajah,1999b). In this context, nonnative English-speaking teachers (NNESTs) face particular challenges related to the prevailing ideologies of English, which has consequences in terms of roles, status, power, and access. This dissertation is a critical discourse analysis of the theses written by twenty in-service teachers of English as a Foreign Language in Colombia on completion of a one-year graduate program, during which they were acquainted with theories, approaches, and methodologies in the field of ELT. The objective is, through a close analysis of the language feature of the texts, 1) to identify ideologies of English, teaching and learning, and 2) to describe the identities the teachers construe for themselves in their writing. The analysis is text-driven and it uses categories from different functional approaches. The analysis of the texts shows that the writers engage in ideological discourses regarding the English language, the social and economic consequences of knowing English, and the cultural aims of foreign language teaching. Their discourses convey conceptions of teaching, learning and research that are influenced by acritical interpretations of the literature available to them. This does not seem to contribute to solving their practical problems and is likely to contribute to the maintenance of the students' established roles in their communities. The teacher-authors are faced with the challenge of dealing with the contradicting interests of their own ideals of education, the constraints of the conventions of the discourse community they are trying to enter, the institutional pressures to be updated with newer trends in applied linguistics and obtain visible results, and the needs of the country to find a place in the globalized economy. The study points to the need to encourage more critical interpretations and applications of the theories and approaches emanating from the traditional academic centers which in turn should also take interest in examining the pattern of the unilateral flow of knowledge and its consequences.

語用能力是語言習得成功重要的一環，但在臺灣高中的英語教學中卻未受到重視。教師的語言行為對於學生在語用和文化價值觀方面有很大的影響，所以檢視英語教師和外籍教師在語言行為是否有相似的策略有其必要性。本文著重在高中英語教師和外籍教師祈令語使用之比較，以瞭解臺灣英語教師的語言行為策略之使用和外籍教師有何異同，並進一步探討文化對語言行為之影響。 本研究利用語文完成測驗問卷(Discourse Completion Task Questionnaire)收集受試者之語料，共有50位本國籍及30位外籍高中英語教師參與研究。問卷資料主要以卡方檢定(Chi-square)，並輔以質性分析兩組受試者之回答。 研究結果指出兩組受試者均使用最多非傳統間接策略(non-conventionally indirect strategies)；但是，本國籍英語教師比外籍教師採用更多直接策略(direct strategies)，外籍教師則比本國籍教師常使用其他策略(other strategies)，例如接受學生的行為或私下約談處理。本研究證實文化的確在語言行為中扮演重要角色，更建議中外籍英語教師均有責任教導學生正確的語用知識，以協助他們在不同情境中和他人成功地溝通。

This study examines the beliefs of foreign language teachers regarding the relative positions of native and nonnative speakers in foreign and second language education. In particular, I am concerned with the idealization of the native speaker in this context and the foreign language anxiety that may occur in nonnative speaker language teachers if they internalize this idealization. I collected data from 29 college-level Arabic and Hebrew teachers using four methods: (1) a questionnaire on their background and beliefs regarding native and nonnative speaker language teachers, (2) a version of the Teacher Foreign Language Anxiety Scale (Horwitz, 2007), (3) a one-on-one interview, and (4) class observation. By and large, study participants believed that native speakers, because of their nativity, have reached higher levels of linguistic and cultural proficiency with relative ease, and as a result are more readily granted credibility as teachers of their native language. Participants believed that nonnative speakers are more empathetic and understanding of their students' problems because of their own experience and efforts as students of the language. With regard to foreign language anxiety, the main sources of anxiety among the nonnative speaker participants were the fear of making mistakes (and losing credibility as a result), of not having the authority to speak on cultural issues, of not being hired when competing with native speakers, and of addressing professional audiences. Native speakers feared that they cannot anticipate or understand as easily as nonnative speaker teachers the difficulties their students have in learning their language, because they cannot relate to their experiences in the same way. Neither group, however, reported feeling particularly anxious overall. I argue that anxiety was minimal for both groups because of specific steps that participants have taken to overcome the perceived disadvantages of their group and thereby bolster their confidence. Participants reported gaining confidence through some combination of the following factors: (1) gaining experience and education, (2) improving their linguistic and cultural proficiency, (3) presenting the persona of a credible language teacher through extra preparation and language choices, (4) receiving external validation, and (5) realizing that everyone can learn from and teach others. / text

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.
