ChatGPT: Features, Strengths, and Use Cases
Key Features of ChatGPT
ChatGPT offers tools designed to simplify teacher workflows and enhance productivity. For instance, educators can create custom GPTs tailored to specific needs, such as a "Lesson Planner" or "Rubric Generator", pre-loaded with state standards or textbook chapters. The Canvas feature allows teachers to draft lesson plans with inline suggestions and export them as PDF or Word documents.
The Deep Research tool compiles information from hundreds of sources into cited reports, making unit planning more efficient. Meanwhile, Advanced Data Analysis transforms performance data into charts and statistics - no coding required. Additionally, the Memory and Projects feature retains key details like grade levels, curriculum standards, and teaching preferences across sessions, ensuring a personalized experience.
These tools form the backbone of ChatGPT's ability to support educators in practical and meaningful ways.
ChatGPT's Strengths for Educators
ChatGPT stands out for its ability to generate content quickly and adapt to various tasks. Its Voice Mode enables real-time spoken conversations, which can be invaluable for language practice or hands-free lesson planning. Another standout feature is Study Mode, which uses Socratic questioning to guide learners with hints rather than providing direct answers.
Research backs up its effectiveness: a meta-analysis of 37 studies found that ChatGPT moderately enhances learning outcomes (g = 0.577). Additionally, 70.2% of students reported saving time by using ChatGPT. However, it's worth noting that GPT-4 has a 28.6% error rate, highlighting the need for careful oversight.
According to Med Kharbach, PhD, Founder of Educators Technology, "ChatGPT serves best as a starting point for professional judgment".
These strengths highlight its potential to support teachers in various professional development scenarios.
Teacher Development Use Cases
ChatGPT's features and strengths translate directly into practical applications for teacher development. For example, 51% of teachers report using ChatGPT daily. In November 2025, OpenAI launched "ChatGPT for Teachers", offering free premium access to verified U.S. K–12 educators through June 2027. Early adopters included major school districts like Dallas ISD, Fairfax County Public Schools, Houston ISD, Fulton County Schools, and the Delaware Department of Education.
In early 2026, a $23 million partnership funded AI training for over 400,000 K–12 educators through the National Academy for AI Instruction. Teachers have used ChatGPT to create tiered prompts tailored to struggling, grade-level, and advanced learners, as well as to develop course-specific GPTs by uploading syllabi and preferred resources. These use cases demonstrate how ChatGPT can be a valuable tool for improving teaching strategies and outcomes.

Gemini: Features, Strengths, and Use Cases
Key Features of Gemini
Gemini takes a fresh approach to teacher development with its seamless integration into Google Workspace. This setup allows educators to access Gemini directly within Google Workspace, eliminating the hassle of switching between apps. The side panel feature makes it easy for teachers to refer to existing Drive files while crafting new lesson plans, ensuring alignment with prior materials.
One of Gemini's standout tools is NotebookLM, a research assistant tailored to work exclusively with teacher-supplied resources like textbooks and curriculum guides. It can generate summaries, study guides, and even podcast-style "Audio Overviews". Another unique feature is the ability to create customizable "Gems" - AI assistants fine-tuned with specific instructions, district standards, or teaching methods. For example, educator Eric Curts launched the EduGems community site, which now offers around 200 teacher-designed Gems for sharing across schools.
Gemini also boasts multimodal capabilities, enabling it to process text, images, audio, and video seamlessly. Teachers can analyze handwritten student notes or create audio lessons to cater to diverse learning preferences. With a context window of up to 1.04 million tokens, the platform can process entire textbooks in a single session. On the privacy front, Gemini ensures compliance with FERPA and COPPA by employing enterprise-grade protections that prevent student data from being used in model training.
These features make Gemini a powerful tool for supporting educators in practical, classroom-focused ways.
Gemini's Strengths for Educators
Gemini's integration with Google Workspace - already utilized by roughly 60,000 U.S. schools - positions it as a natural fit for districts that rely on Google's ecosystem. What sets Gemini apart from general-purpose AI platforms is its LearnLM model, which is specifically fine-tuned for educational psychology. Research shows that students working with LearnLM were 5.5 percentage points more likely to solve complex problems compared to those guided solely by human tutors.
The platform's Guided Learning Mode uses Socratic questioning to encourage educators to think critically rather than simply providing answers. Additionally, Gemini shines in administrative automation through its Workspace Studio, where teachers can design no-code AI tools to handle tasks like managing emails, organizing permission slips, and keeping track of attendance.
Teacher Development Use Cases
Gemini's robust features translate into real-world benefits for teacher development. In late 2025, a suburban school district ran a 12-week blended professional development program focused on math formative assessment. The program combined an AI tutor with weekly lesson studies led by district coaches. The results? A 35% reduction in planning time, a 20% improvement in observation scores, and a 9% increase in student assessment performance. These outcomes highlight the effectiveness of Gemini's Guided Learning Mode and Workspace Studio.
"Product manager Vivek Chachcha reported that teachers used Gemini to customize math assignments by centering them on Taylor Swift's Eras Tour - calculating ticket sales and attendance - which resulted in measurable increases in student engagement".
Additionally, Gemini's "re-level" feature allows teachers to adjust reading materials or assignments to match different reading levels, making it a valuable tool for differentiated instruction.
