Daniel Xerri is an Associate Professor in Applied Linguistics and TESOL at the University of Malta, and the Chairperson of the ELT Council. His talk will explore prompt engineering as a powerful tool to enhance language learning and instruction. Prompt engineering involves crafting effective prompts, or instructions, to elicit desired responses from generative AI models. In the educational context, prompt engineering can be used to create personalized learning experiences, generate creative writing prompts, automate assessment tasks, and facilitate research. Participants will learn how to design prompts that are clear, specific, and engaging, as well as strategies for evaluating and refining prompt effectiveness. This talk will provide educators with the knowledge and skills necessary to harness the power of prompt engineering to transform language teaching and learning.
