Generative AI: Experiments in Writing and Learning

 
Abstract: Emerging generative AI tools like ChatGPT present intriguing opportunities to enhance writing instruction by helping learners manage cognitive load, exercise fluency, and receive real-time formative feedback. Yet, these technologies will also challenge educators to reshape traditional learning design and assessment practices. Adapting will involve fundamental shifts in our mindsets and how we conceptualize student learning. First, students will need to develop capacities for self-regulated learning as they increasingly act as the “human in the loop” for their own AI-assisted writing and learning processes. Second, educators will need to focus on promoting discipline-specific forms of evaluative judgment to help students self-assess and improve as they engage in AI-assisted work. Finally, both students and educators will need to develop AI literacies that allow them to productively and ethically interact with these technologies to support social learning and professional development. This presentation will report on an experimental fall 2023 course on “Artificial Intelligence and Writing” that seeks to put these principles into action. It will share learning designs for the course’s weekly creative challenges which provide students engaging opportunities to experiment and reflect on the use of specific AI tools and techniques. Preliminary findings from these creative challenges will be used to reflect on the future of AI-assisted writing and learning.

Large language models in hybrid natural-language processing applications for language learning and assessment

 
Abstract: In this presentation, I will explore the affordances of large language models (LLMs), such as GPT, for building hybrid natural-language processing (NLP) applications in the fields of computer-assisted language learning and assessment. In these hybrid applications, the LLMs are combined with rule-based components that drive the LLMs in generating and understanding natural language. This permits the developer to retain control over the pedagogical or assessment procedures while simultaneously tapping into the power of the LLMs for flexible language generation and understanding. Specifically, I will discuss the affordances of LLMs in the context of three past and ongoing projects that focus on (1) the assessment of L2 interactional competence, (2) the learning of L1 argumentation discourse, and (3) the learning of text-production strategies for integrated writing tasks.

Generative AI and the end of corpus-assisted data-driven learning? Not so fast!

 
Abstract: This talk explores the potential advantages of corpora over generative artificial intelligence (GenAI) in understanding language patterns and usage, while also acknowledging the potential of GenAI to address some of the main shortcomings of corpus-based data-driven learning (DDL). One of the main advantages of corpora is that we know exactly the domain of texts from which the corpus data is derived, something that we cannot track from current large language models underlying applications like ChatGPT. We know the texts that make up large general corpora such as BNC2014 and BAWE, and can even extract full texts from these corpora if needed. Corpora also allow for more nuanced analysis of language patterns, including the statistics behind multi-word units and collocations, which can be difficult for GenAI to handle. However, it is important to note that GenAI has its own strengths in advancing our understanding of language-in-use. For example, GenAI’s ability to generate results from almost any register, domain or even language can greatly widen the scope of DDL beyond its current focus on tertiary academic English language. Additionally, the size and speed at which current large language models like ChatGPT can be queried is unprecedented with even the best available corpus tools. I argue that both corpora and GenAI have valuable roles to play in advancing our understanding of language-in-use. By combining these approaches, language learners can gain a more comprehensive understanding of how language works in different contexts than is currently possible using only a single approach.

Expanding Pedagogy: New Ways of Teaching, Learning and Assessment with AI

 
Abstract: As we come to understand the affordances and limitations of generative AI, it is time to flip the narrative away from “How will AI impact education?” to “What are new and effective ways of teaching and learning enabled by AI?”. In this presentation I will explore how AI can support innovative pedagogy. Roles for generative AI include: Possibility Engine (AI generates alternative ways of expressing an idea), Socratic Opponent (to develop an argument), Collaboration Coach (to assist group learning), Exploratorium (to investigate and interpret data), Personal Tutor and Dynamic Assessor. I propose that future research into generative AI for education should be based on a new science of learning with AI – to include understanding cognitive and social processes of AI-assisted learning, exploring future roles for AI in education, developing generative AI that explains its reasoning, and promoting ethical education systems.

Critical Project-Based Learning and Social Justice: Implications for Digital Citizenship

 
Abstract: Computer-Assisted Language Learning (CALL) tends to be portrayed as a value-neutral field of practitioner research that is concerned with access to or use of digital technologies, particularly to enhance language proficiency, motivation or flexible learning. Such a view of digital education is often highly deterministic and may ignore the material realities and role of people in shaping the technologies we use. This struggle is again being played out in the hype that has greeted the emergence of ChatGPT and related AI technologies. Although confronted with challenges in testing-based educational systems, Project-Based Language Learning (PBLL) has become a more prominent pedagogical approach in recent years and research suggests that when used alongside CALL it may “engage language learners with real-world issues and meaningful target language use through the construction of products that have an authentic purpose and that are shared with an audience that extends beyond the instructional setting” (NFLL, 2022). The “real-world” dimension of PBLL and digital education can, however, be easily assimilated into neoliberal notions of education as skills training or mere preparation for the world of work. This presentation considers the value of a more critical approach to CALL and PBLL through the lens of the ‘social justice and sustainability turn’ in language education to consider how it may aid language learners and teachers to understand social and economic inequalities and to develop more critical notions of digital citizenship.

Adaptive language learning in the new age of generative AI

 
Abstract: Nowadays, generative AI (genAI) technologies such as ChatGPT and GPT 4 have become the new catchwords in education. The potential of genAI has been exploited in many domains of education, including adaptive language learning. Although genAI can support the development of some functionalities of adaptive learning, such as creating extended language inputs and associated learning exercises and assessments and providing feedback on language outputs, I argue that designing a robust, learner-first adaptive learning experience requires a principled, systematic approach, where genAI is only a facilitating tool, not a solution.

Learner-first adaptive learning solutions, where a learner’s needs and wants are prioritized every step of the way when he/she interacts with the assessments and learning content, are rare. This is because developing such solutions requires interdisciplinary talents in assessment, learning, cognitive and noncognitive science, artificial intelligence (AI), and many more, which, in reality, is a luxury for most development teams. How do we ensure a learner-first assessment and learning experience? In designing various types of assessments in adaptive learning, we want the assessments to be efficient yet precise, unobtrusive, provide actionable information, and support a positive assessment taking experience. A learning experience optimized for an individual learner must meet his/her unique learning needs, and be tailored to his/her level, dynamic knowledge and skill profiles, cognitive and learning styles, and constantly changing affective states to facilitate the most speedy and effective learning.

In this talk, I will discuss the science and technologies behind an adaptive learning system, especially how the emergence of genAI could potentially empower the development of materials and assessments in an efficient way. I will decompose the architecture of an adaptive learning system, focusing on the chain of inferences supporting its overall efficacy, including user property representation, user property estimation, content representation, user interaction representation, user interaction impact, and system impact. I will provide an overview of different types of assessment used in adaptive learning and an analysis of the assessment approach, priorities, and design considerations of each to optimize its use in adaptive learning. I will then propose a framework for evaluating different aspects of an adaptive learning system. I will conclude with thoughts on high priority research and development to provide truly learner-first systems to fully empower our learners and the expanding role of genAI in future development of adaptive learning solutions.
