Description
The speech of non-native (L2) speakers of a language contains phonological rules that differentiate them from native speakers. These phonological rules characterize or distinguish accents in an L2. The Shibboleth program creates combinatorial rule-sets to describe the phonological pattern of these accents and classifies L2 speakers into their native language. The training and classification is done in Shibboleth by support vector machines using a Gaussian radial basis kernel. In one experiment run using Shibboleth, the program correctly identified the native language (L1) of a speaker of unknown origin 42% of the time when there were six possible L1s in which to classify the speaker. This rate is significantly better than the 17% chance classification rate. Chi-squared test (1, N=24) =10.800, p=.0010 In a second experiment, Shibboleth was not able to determine the native language family of a speaker of unknown origin at a rate better than chance (33-44%) when the L1 was not in the transcripts used for training the language family rule-set. Chi-squared test (1, N=18) =1.000, p=.3173 The 318 participants for both experiments were from the Speech Accent Archive (Weinberger, 2013), and ranged in age from 17 to 80 years old. Forty percent of the speakers were female and 60% were male. The factor that most influenced correct classification was higher age of onset for the L2. A higher number of years spent living in an English-speaking country did not have the expected positive effect on classification.

Unschooling is a child-centered educational philosophy that eschews teachers,
schools, curricula, grades and tests. Unschool practitioners have complete freedom to choose what they want to learn, when, to what level, and for how long. Unschooling families use the World Wide Web to provide a bespoke academic experience at home. This study compares qualitative data collected from questionnaires and semi-structured interviews conducted with 10 unschooling families with quantitative data collected from 5 children within these families using a tracking and monitoring software. The software captured the duration of use, keystrokes, mouseclicks, and screenshots for all programs and websites for 14 days. Children stated they used technology less than 6 hours a day, and parents stated children used them less than 8 hours a day. Quantitative data shows the children use technology at least 10 hours a day, suggesting usage self-reports may not be reliable. The study revealed hardware form factor was the number one determinate of application use. Almost exclusively social media was used on smartphones, internet browsing on tablets, and creative endeavors such as modding, hacking, fan fiction writing, and video game level building all took place exclusively on laptops and desktops. Concurrent use of differing hardware form factors was the norm observed. Participants stated YouTube, Wikipedia and Khan Academy were the websites most used for knowledge gathering. The tracking software verified YouTube and Wikipedia were the most used websites, however when accessed on the PC, those sites were used almost exclusively for video game related purposes. Over 90% of the total PC use was spent on video games. More traditional educational activities were done primarily on tablets and on parent smartphones with parental engagement. Khan Academy was not used by the
participants in the 14 day monitoring period. 90 day web browser logs indicated Khan Academy was used by individuals no more than 3 times in a 90 day period,
demonstrating the inherent risks in relying upon internet usage self-reports without
quantitative software for verification. Unschooling children spent between 30 and 60 hours a week using technology.

Description
The field of authorship determination, previously largely falling under the umbrella of literary analysis but recently becoming a large subfield of forensic linguistics, has grown substantially over the last two decades. As its body of research and its record of successful forensic application continue to grow, this growth is paralleled by the demand for its application. However, methods which have undergone rigorous testing to show their reliability and replicability, allowing them to meet the strict Daubert criteria put forth by the US court system, have not truly been established.
In this study, I set out to investigate how a list of parameters, many commonly used in the methodologies of previous researchers, would perform when used to test documents of bloggers from a sports blog, Winging It in Motown. Three prolific bloggers were chosen from the site, and a corpus of posts was created for each blogger which was then examined for each of the chosen parameters. One test document for each of the three bloggers which was not included in that blogger’s corpus was then chosen from the blog page, and these documents were examined for each of the parameters via the same methodologies as were used to examine the corpora. Once data for the corpora and all three test documents was obtained, the results were compared for similarity, and an author determination was made for each test document along each parameter.
The findings indicated that overall the parameters were quite unsuccessful in determining authorship for these test documents based on the author corpora developed for the study. Only two parameters successfully identified the authors of the test documents at a rate higher than chance, and the possibility exists that other factors may be driving these successful identifications, demanding further research to confirm their validity as parameters for the purpose of authorship work.

Description
This study examines ninth graders’ negotiation of meaning with one canonical work, Romeo and Juliet. The study’s sample was 88% Latino at a Title I high school. The study adopts a sociocultural view of literacy and learning. I employed ethnographic methods (participant observation, data collection, interviews, and focus groups) to investigate the teacher’s instructional approaches and the literacy practices used while teaching the canonical work. With a focus on students’ interpretations, I examined what they said and wrote about Romeo and Juliet. One finding was that the teacher employed instructional approaches that facilitated literacy practices that allowed students to draw on their cultural backgrounds, personal lived experiences, and values as they engaged with Romeo and Juliet. As instructional approaches and literacy practices became routine, students formed a community of learners. Because the teacher allowed students to discuss their ideas before, during, and after reading, students were provided with multiple perspectives to think about as they read and negotiated meaning. A second finding was that students drew on their personal lived experiences, backgrounds, and values as they made sense and negotiated the meaning of Romeo and Juliet’s plot and characters. Although the text’s meaning was not always obvious to students, in their work they showed their growing awareness that multiple interpretations were welcomed and important in the teacher’s classroom. Through the unit, students came to recognize that their own and their peers’ understandings, negotiations, and interpretations of the canonical work were informed by a variety of complex factors. Students came to find relevance in the text’s themes and characters to their experiences as adolescents. The study’s findings point to the importance of allowing students to draw from their cultural backgrounds and experiences as they negotiate meaning with texts, specifically canonical ones, and to welcome and encourage multiple meanings in the English classroom.

Description
In this study, I investigate how secondary reclassified ELLs use the Learning Management System Schoology in three secondary English classrooms. Particularly, I focus on the digital literacy practices reclassified ELLs use as they navigate Schoology to complete a multi-page research paper. In examining the digital literacy practices of secondary reclassified ELLs who have recently exited the language development program, I add to research in the fields of New Literacies and Multiliteracies, sociocultural approaches to learning, and identity studies.
In this qualitative study, I employed ethnographic techniques (i.e., data collection, participant observation, interviewing, and collection of archived material and digital artifacts stored in Schoology). I drew from communities of practice and identity frameworks to examine focal participants' literacy practices when participating in the online space of Schoology and provided screenshots to showcase this participation. I examined email exchanges that were co-created by teacher and student that demonstrated their reliance on a digital tool to continue the teaching and learning processes. I exhibit screenshots of focal participants' engagement with the revision process as they used Schoology’s and Microsoft Word's digital editing tools. Finally, I examined focal participants' participation in Schoology's online discussion forum to highlight how they revealed aspects of their identities and performed these identities in a mainstream-learning environment as well.
My analysis establishes that focal participants' access to an LMS like Schoology and other digital spaces (e.g., email) supports the language learning and literacy practices of reclassified ELLs. In addition, my analysis of focal participants' digital and communication practices shows that they contributed to their agency, positioned themselves as empowered and knowledgeable learners, and performed the role of "peer as mentor" when providing feedback to their peers. Finally, in my analysis of focal participants' inventories of digital literacy practices, I discovered that their engagement in Schoology for the purposes of learning and communication reinforced their language learning, both traditional and digital literacies, and overall academic achievement. Findings of this study emphasizes the importance of technology integration at the secondary level so that all students have equal access to digital and multimodal ways of learning in today's digital age.
