The developers of GAI tell us that tools such as ChatGPT and Bard, also known as "large language models" or LLMs, work by predicting the flow of language. GAI uses publicly available sources to "recognize the relationships that most commonly exist between individual units of meaning (including full or partial words, phrases and sentences)" (Hoffman, 2023). According to Chat GPT (2023, August) itself, this type of artificial intelligence
...is designed to generate human-like text based on the input it receives. For this to happen, the model is trained on a massive amount of text data from the internet. It learns to predict the next word in a sentence, which helps it capture grammar, syntax, and some level of world knowledge. The result is a 'pre-trained' model with knowledge of language patterns and facts. After pre-training, the model is fine-tuned on specific tasks using more narrow and focused datasets. This process tailors the model's behavior to perform certain tasks, like language translation, text completion, or question answering. The GPT architecture employs attention mechanisms that allow it to weigh the importance of different words in a sentence and generate coherent and contextually relevant responses. The large number of parameters (weights) in the model, often in the tens or hundreds of billions, enables it to generalize well to various tasks and generate text that is often remarkably coherent and contextually appropriate.
ChatGPT was trained on a large corpus of material; as it was developed, humans interacted with the model, ranking answers it gave so that it could learn which were better responses. Essentially, this model can recognize, summarize, and predict text based on giant data sets (Northwestern University, 2023).
GAI has the potential to improve certain aspects of higher education. For example, Rutter and Mintz (2023) believe that GAI may be able to help students with traditionally under-funded areas of university life such as career counseling. For administrative work, GAI can act as an assistant, taking notes and providing meeting summaries. Available built in tools include:
Generative artificial intelligence technology is currently not in FERPA compliance. Using GAI to record students is not recommended.
For course development and classroom work, GAI can be used to help design lessons and assignments and help students produce better work. Some ways that GAI can be used effectively in courses include:
- Drafting of assignment prompts.
- Drafting of syllabi.
- Suggestions for project topics.
- Keywords for library database searching.
- Editing for grammar
- Outlining a project
- Solving math problems (when the student knowing the process is not critical).
- Coding, providing code snippets, explanations of programming concepts, and debugging assistance.
Naturally, any material generated by any form of artificial intelligence should be proofread, personalized, improved, and appropriately cited.
