Retrieval-Augmented Generation (RAG) is a powerful technique to ground LLMs on external data. This enhances the relevance of responses and helps reduce hallucinations by providing context. #RAG #LLMArchitecture

Control the randomness of LLM outputs using temperature or top_p parameters. Lower values yield deterministic results, while higher values increase creativity and diversity.

Large Language Models (LLMs) process text by converting it into tokens. For English, a token is roughly 4 characters or 0.75 words. Managing tokens is vital for cost and performance.

Isaac Asimov introduced his famous Three Laws of Robotics in 1942, establishing a hierarchy for robotic decision-making, like prioritizing preventing harm over following orders. #Robotics #AIHistory

Imagine assessment that focused on:: habits, comparison to others, & ability to create valued work.

There's growing recognition that diverse assessment data is needed for a complete picture of student learning, beyond traditional tests.

Today, I encountered what appears to be Chinese characters in a generative AI response.

Before AI can be widely adopted, people must trust it, especially that it can make accurate and fair decisions. AI should be aware of and aligned with human values. #TrustInAI #AIAdoption

Biased humans contributing to AI data is another source of bias. Human discrimination in areas like the labor market can become manifest in computer algorithm.

Facial recognition algorithms developed in East Asia performed better on Asian subjects, while Western algorithms performed better on White subjects. This discrepancy is attributed to different racial distribution in training sets. #TrainingData #AIAccuracy

An AI might correlates a zip code with better employee performance and incorrectly assumes the zip code causes the performance.

One way AI decisions become biased is by confusing correlation with causation. Just because two variables change together doesn't mean one causes the other. #AIFallacy

AI is increasingly used for critical decisions in hiring, loans, medicine, and more. While AI can perform certain tasks more accurately than humans, using computers doesn't automatically eliminate bias.

Negotiating technology sufficiency in schools involves balancing the capacity of systems/devices, the number of devices, how they are available, and teacher preparation.

Learning outside school is often socially embedded, interest-driven, and opportunity-oriented. Students arriving in classrooms are active & independent learners due to digital experiences.

IT affects both the nature of human brains and behaviors. The digital media landscape is much more participatory than the print-dominated one before it.

Newer pedagogical models call for students to be more active in defining curriculum, building knowledge, and communicating what they've learned. These emphasize complex problems & social interaction. #StudentCenteredLearning

Humans are a technology-using species. Through IT, we extend our capacity to interact & manipulate the environment, being both social & technological at once,

Early electronic media like radio had inconsequential effects on classrooms, but modern digital tech is different, becoming the default for communication.

Technology stewards are leaders who discover, invent, and share the practices for using IT to accomplish the logistic and strategic goals of the Communities of Practice. #TechLeadership
