Description
Graph theory is a critical component of computer science and software engineering, with algorithms concerning graph traversal and comprehension powering much of the largest problems in both industry and research. Engineers and researchers often have an accurate view of their target graph, however they struggle to implement a correct, and efficient, search over that graph.
To facilitate rapid, correct, efficient, and intuitive development of graph based solutions we propose a new programming language construct - the search statement. Given a supra-root node, a procedure which determines the children of a given parent node, and optional definitions of the fail-fast acceptance or rejection of a solution, the search statement can conduct a search over any graph or network. Structurally, this statement is modelled after the common switch statement and is put into a largely imperative/procedural context to allow for immediate and intuitive development by most programmers. The Go programming language has been used as a foundation and proof-of-concept of the search statement. A Go compiler is provided which implements this construct.

Description
Language Textbooks often play a major role in English for speakers of other languages (ESOL) classrooms, not only to provide information but also to help students construct their identities. Several studies showed that identity and language learning are inseparable, due to the simple fact that every learner has his/her own identity aspects like race, gender, social class, and speaker status (i.e., native speaker vs. non-native speaker of the target language). These aspects should be acknowledged because providing the students with limited identity options might cause the students to resist learning the language or be less invested in this practice (Norton & Toohey,2011).
However, there is limited support for teachers who wish to examine identity in ESOL textbooks. Several scholars attempted to evaluate the range of identity options offered in ESOL textbooks, but they all used either Critical Discourse Analysis or Content Analysis which can be effective; however, these procedures require training and can take a long time, so they may not be practical for teachers. This suggests that there is a need for a less complicated evaluation tool that can be easily used by teachers.
The purpose of this thesis is to develop a teacher-friendly identity-focused checklist for ESOL textbooks, and the thesis is guided by the following questions: (a) what would an evaluation checklist for identity in ESOL textbooks look like?; (b) what can this checklist reveal about ESOL textbooks? The purpose of this thesis was achieved by developing a qualitative checklist that covers, race, gender, social class, and speaker status, and demonstrating how to use it on a collection of five adult ESOL textbooks. The checklist revealed similarities and differences between the textbooks, including important shortcomings, and that kind of information can be useful for the teacher to make decisions about the textbook he/she uses.

Description
Globalization is driving a rapid increase in motivation for learning new languages, with online and mobile language learning applications being an extremely popular method of doing so. Many language learning applications focus almost exclusively on aiding students in acquiring vocabulary, one of the most important elements in achieving fluency in a language. A well-balanced language curriculum must include both explicit vocabulary instruction and implicit vocabulary learning through interaction with authentic language materials. However, most language learning applications focus only on explicit instruction, providing little support for implicit learning. Students require support with implicit vocabulary learning because they need enough context to guess and acquire new words. Traditional techniques aim to teach students enough vocabulary to comprehend the text, thus enabling them to acquire new words. Despite the wide variety of support for vocabulary learning offered by learning applications today, few offer guidance on how to select an optimal vocabulary study set.
This thesis proposes a novel method of student modeling which uses pre-trained masked language models to model a student's reading comprehension abilities and detect words which are required for comprehension of a text. It explores the efficacy of using pre-trained masked language models to model human reading comprehension and presents a vocabulary study set generation pipeline using this method. This pipeline creates vocabulary study sets for explicit language learning that enable comprehension while still leaving some words to be acquired implicitly. Promising results show that masked language modeling can be used to model human comprehension and that the pipeline produces reasonably sized vocabulary study sets.

Description
Creativity is increasingly cited as an educational goal in many international contexts and as a facet of academic and economic success. However, many myths surround creativity that impede its facilitation in the classroom: it is an individual talent, not teachable, and not relevant to adult life outside of artistic domains. Further, perceptions of creativity are largely informed by treatment in North American contexts. In second language instruction, linguistic creativity in particular faces greater hurdles for recognition and value, as language learners’ creative language use is often treated as error. In this paper, I argue that creative pedagogies and second language instruction can inform each other; creative pedagogy can lead to greater recognition of the creative power of language learners, and second language research can provide a cultural lens through which to gain understanding of how creativity is enacted in language. To argue that creativity facilitates language learning and is a necessary component of proficiency, I employ B. Kachru’s (1985) notion of bilingual creativity to demonstrate the ubiquity of linguistic creativity in the lives of bilingual language users. With support from Carter (2016) and G. Cook’s (2000) works on everyday creative language and language play, respectively, I demonstrate the value of linguistic creativity for language learning and language socialization. I end by suggesting five guidelines for second language instructors interested in implementing a creative pedagogy framework: (1) promote reflection and noticing in learning and creativity, (2) offer authentic models of linguistic creativity, (3) provide emotion language and multiple methods for emotional expression in interaction, (4) allow for a fusion of L1 and L2 linguistic and cultural knowledge, and (5) respond actively to opportunities for collaborative creativity.
