*In order to highlight the rapid emergence of artificial intelligence—and to reflect the uncertainty and indeed ominousness felt by many observers of AI’s rise—we created all images (unless otherwise noted) using DALL-E, a deep-learning model developed by OpenAI to generate digital images from natural language descriptions. After generating the images using keyword prompts from the text of the story and additional descriptions such as “futuristic” or “steampunk,” a graphic designer then modified the images digitally into their final form.

USING AI IN DEAF EDUCATION

NAOMI CASELLI, ASSISTANT PROFESSOR OF DEAF EDUCATION AND CODIRECTOR OF THE BU AI & EDUCATION INITIATIVE

Work on sign languages has lagged behind spoken languages in part because we haven’t had the tools to measure sign language production. AI may be able to help. Our understanding of how people produce and perceive speech has benefited from a host of tools for automatically transcribing speech, identifying which speech sounds are being produced, and taking detailed measurements of the quality of speech sounds and the position of the tongue and mouth.

New advances in computer vision are making it possible for us to take similar measurements of signs. We have begun to utilize human pose estimation—a computer vision-based technology that identifies and tracks specific points on the human body—to locate the hands and fingers as a signer produces a sign, which we have used to teach a computer how to recognize what a person is signing. While I worry about the ethical implications of language technologies—like pressure to replace rather than augment human teachers and interpreters—I am eager to see progress on AI-powered sign language computing help to make language technology accessible to sign language users.

AI and Language Education

Ashley Moore, Assistant Professor of Language & Literacy Education

I’m feeling an equal mix of hope and concern. On one hand, colleagues at BU have used ChatGPT to quickly create first drafts of reading texts at the appropriate level for their students. Learners who lack a conversation partner have exploited ChatGPT as a functional—yet still rather unexciting—target language partner. Similarly, a learner who’s unable to afford a personal language tutor can use a generative AI tool to suggest edits on an early draft of their written work and hopefully learn from those changes.

But because AI tools draw from huge amounts of existing data, they tend to reproduce dominant linguistic practices, threatening linguistic diversity and exacerbating linguistic discrimination. For example, we’ve spent decades trying to undo the myth that it’s necessary or even desirable for learners to mimic the language practices of so-called native speakers. However, some companies are already marketing AI chatbots that “mimic the culture, behavior, and gestures of native English speakers” in “authentic” conversations. Similarly, just as some users of global English varieties are successfully asserting the equal legitimacy of their English, the use of AI as a proofreader threatens to flatten that linguistic diversity into standardized forms of English associated with white, middle-class native speakers from countries like the United States.

Evaluating Internet Credibility With AI

Elena Forzani, Assistant Professor of Literacy Education

AI changes the practice of evaluating credibility on the internet positively and negatively. First, the negative: tools like ChatGPT don’t necessarily write credible, representative texts by gathering information from diverse sources and representing marginalized voices. In constructing texts, ChatGPT can produce, or reproduce, inaccurate, biased information. Thus, AI can actually create an echo chamber of misinformation, perpetuating inaccurate ideas.

Using AI to Predict College and Career Readiness

V. Scott H. Solberg, Professor of Counseling Psychology & Applied 人类发展

Pandemic-related learning loss and disengagement among high school and college students amplified concerns that this generation of youth will not be ready to maximize their potential in today’s world of work. Nationally, only 60 percent of high school graduates enter a two- or four-year postsecondary program; only 36 percent and 58 percent graduate, respectively, our research has shown. We’ve also found that nearly 12 percent of young adults aged 19 to 27 are disconnected from work and education. Those working full-time average less than $13 per hour, with less than 35 percent earning more than their state’s “living wage” benchmark.

In collaboration with colleagues in BU’s College of Arts & Sciences—Derry Wijaya, an assistant professor of computer science; Sarah Bargal, a research assistant professor of computer science; and Chenwei Cui (GRS’23)—I am working to create a reliable and scalable assessment tool that alerts educators and colleges whether and to what extent students are setting high future aspirations and proactively engaged in striving to realize those aspirations. Using career narratives collected from 1,000 high school students, we are studying whether large language models such as BERT, PaLM, LLaMA, and GPT that now achieve state-of-the-art performance on many benchmark natural language processing tasks can achieve reliable results in predicting career readiness levels among high school youth. This solution has major implications as an assessment tool to monitor individual youth progress through secondary education, as well as a tool postsecondary
institutions can use to assess applicants.

Assessing Teacher Quality with AI

Nathan Jones, Associate Professor of Special Education and founding member of BU’s Faculty of Computing & Data Sciences

My research centers on how we think about and identify effective teaching among practicing teachers and how we maximize learning experiences among preservice teachers. 

One area where I see promise in AI is in increasing the frequency and quality of feedback we’re able to provide beginning educators. For the past several years, I’ve been leading a National Science Foundation–funded project to improve preservice general educators’ ability to use instructional practices known to support students with disabilities in mathematics. As part of this project, we have developed an innovative set of performance tasks, where candidates respond to brief instructional scenarios in an internet-based environment. These performance tasks give researchers information on whether candidates have developed the skills we’ve been teaching them.
