Two AI Tools That Transform Teachers' Class Preparation
Joo-Hyeon Joo, CEO of __T100009_____, introduced Redmenta and Snorkl during a GEG Daejeon webinar. The hour-long session covered two different AI training platforms: text-based and voice-based. A guidebook link was shared at the start of the lecture. This resource was designed to address the practical challenges of using YouTube lecture videos alone. It included a Redmenta guide and a snorkel guide. Redmenta's new direction Redmenta, a Hungarian company, is an education platform equipped with 160 AI-powered tools. Just two years ago, creating worksheets with AI in one click was a trend. Now, anyone can do it. Google also offers generative AI capabilities for free through Gemini. So Redmenta changed its strategy. Starting this year, conversations with AI and content creation are completely free. There are no restrictions. Instead, credits are only awarded for the evaluation function. While anyone can create content, the strategy emphasizes the importance of accurate evaluation and feedback. A system that uses three AI models simultaneously Redmenta utilizes all three AI models: GPT, Gemini, and Claude. This represents a shift in edtech AI beyond 2024. While previously relying on a single AI platform, Redmenta now tests all three models within a lab within the platform. GPT excels at math problems, while Claude excels at writing. The optimal AI is automatically selected and used based on the situation. The AI-based approach is no longer crucial. We've entered an era where the entire system is leveraged. Practical Use: Creating Custom Worksheets The main representative typed "custom" on the screen. Redmenta has 160 AIs, but too many can be difficult to find. That's why we use an AI-to-AI approach. When you search, it recommends the right tool. I uploaded a PDF file of a high school English textbook. The text was extracted, and I asked, "Let's design a plan for how to use this with first-year high school students." The AI suggested a structure for each lesson. However, instead of creating it right away, we could enter conversation mode and design it together. When I asked again, "Instead of just creating a worksheet, let's design a lesson together," the AI began asking step-by-step questions. It asked about learning objectives, core competencies, and other topics, and worked with the teacher to develop the lesson. Similar to ChatGPT, it specialized for education, providing more tailored answers. Audio generation and AI chat features When creating an English question, I requested, "Let me take an English listening test, talk to the AI, and finally write an essay." The AI created all the questions in English and even generated the voice. The sentence, "My family is very important to me," was played in a natural voice. You can create various types of audio, such as conversations between men and women or between friends. It works in all languages, not just English. It's also downloadable, so you can use it for other purposes. You can even embed an AI chatbot within a worksheet. When a student types "Hello," the AI initiates a conversation in English. If a student asks in Korean, it responds in Korean as well. Teachers can customize the AI's behavior. If a student wanders off topic, it can prompt them to return or explain why. While some teachers may have used chat-based tools like Mizou, Redmenta differs in that it allows you to embed worksheets within the chat. You can even create a chat and give it to students. It's a conversational learning approach. Creating a Feedback Character Before assigning assignments to students, teachers can define the nature of AI feedback. By specifying specific details like "Always praise students for their work, kindly address areas where they need help, and end with a cheerful tone," the AI will provide feedback in that style. The test results yielded feedback along the lines of, "Great! I'm so impressed by how hard you worked on task 2." The AI embodies the teacher's character. Personalized learning and group management
