Functionalities

Lecture Transcription and Polishing:

Transcriptto begins by transcribing audio or video lectures. The transcription is then polished for clarity, conciseness, and relevance, removing any redundant or semester-specific details.

Topic Identification and Segmentation:

The application identifies key topics within the lecture and segments the content into manageable parts. This segmentation is crucial for breaking down lengthy lectures into focused, digestible modules.

Educational Material Generation:

Beyond transcription, Transcriptto auto-generates various educational materials.

This includes:

• Quizzes and Discussion Questions: Based on the lecture content, to facilitate active learning and comprehension.
• Instructional Objectives: Outlining the key learning goals for each segment.
• Slide Creation: Transforming content into PowerPoint slides, complete with titles, bullet points, and notes.

System Architecture:

Transcriptto's architecture is designed to streamline the lecture preparation process for educators, integrating several sophisticated technologies. The workflow from input to output is meticulously engineered to ensure efficiency and quality. Faculty members can input their lectures in various formats – video, audio, or text. This flexibility allows educators to choose the most convenient format for their teaching style and available resources.

Conversion and Transcription:

·Video to Audio Conversion: For video inputs, Transcriptto utilizes FFmpeg, a powerful multimedia framework, to extract the audio component from the video file.

·Audio to Text Transcription: The extracted audio or directly inputted audio files are then transcribed into text. This step is powered by OpenAI’s Whisper model, known for its accuracy in transcription and its ability to handle different accents and audio qualities.

Content Processing and Enhancement:

·Text Tokenization: The transcribed text is broken down into smaller segments or tokens, making it easier for subsequent processing. This step is crucial for managing and organizing the content efficiently.

·Topicalization: Using AI, specifically the ChatGPT model, Transcriptto identifies key topics within the text, categorizing and highlighting the main subjects of the lecture.

·Content Polishing: The text is then polished to enhance clarity, remove redundancies, and ensure it is engaging and educational. This involves refining the language and structure of the content.

Educational Material Generation:

·Learning Objects Creation: Transcriptto generates various educational materials such as quizzes, discussion questions, and instructional objectives. These are crafted based on the content of the lecture, ensuring alignment with educational goals.

·Slide Creation: The content is transformed into PowerPoint slides using the Python pptx library. This process incorporates best practices in educational slide design, focusing on student engagement and learning.

Instructional Objectives with Bloom’s Taxonomy and Best Practices:

One of the standout features of Transcriptto is its sophisticated approach to generating instructional objectives. To ensure these objectives are not only relevant but also pedagogically sound, Transcriptto utilizes carefully crafted prompts that incorporate established best practices in educational design. These prompts are designed to guide ChatGPT in the creation of measurable and effective learning objectives.

At the core of Transcriptto’s approach is the application of Bloom’s Taxonomy, a widely recognized framework in education. This taxonomy categorizes learning objectives into different levels, ranging from basic knowledge and comprehension to more advanced analysis, synthesis, and evaluation. By incorporating Bloom’s Taxonomy, Transcriptto ensures that the generated objectives are comprehensive and cater to a range of cognitive levels, enhancing the depth and breadth of learning.

Transcriptto’s prompts are specifically designed to guide the AI in creating objectives that are measurable and achievable. This means that each learning objective clearly defines what students should be able to do after completing a segment of the course. Such clarity is crucial for both instructors and students to understand and assess the learning outcomes effectively.

The tool also ensures that the learning objectives are closely aligned with the content of each lecture segment. This alignment guarantees that the objectives accurately reflect the material covered and guide students towards the intended learning outcomes.

Recognizing the diverse needs of different courses and teaching styles, Transcriptto allows for customization in the creation of instructional objectives. Educators have the flexibility to modify the AI-generated objectives or to provide additional input to tailor the objectives more closely to their specific course requirements.

By leveraging AI in conjunction with Bloom’s Taxonomy and best practices in instructional design, Transcriptto stands out in its ability to generate high-quality, educationally sound objectives. This feature not only aids in creating a structured learning path for students but also supports faculty in the effective delivery of course content.

Transcriptto features a configuration file, allowing users to customize various aspects without deep programming knowledge. This includes setting preferences for transcription, topic segmentation, and material generation.

Slide Creation: Engaging Learning through Effective Design

In the methodology section for slide creation, it is essential to focus on best practices that enhance learning, especially when transforming content into PowerPoint slides for online education. This approach involves creating slides for learning, not just for teaching, by breaking down concepts and maintaining engagement with frequent changes in visual stimuli.

Research emphasizes the importance of presenting material in short phrases rather than full paragraphs. This practice aids in comprehension and retention, as it aligns better with how students process information visually and auditorily. A balance between spoken words and visual elements, such as relevant pictures, is recommended to optimize cognitive load and enhance learning.

To maintain student engagement, especially in an online setting where attention can wane, it's crucial to keep slide content dynamic. This can be achieved by changing the content on the screen frequently and avoiding prolonged periods with the same visual stimuli. Simple cues such as text size, bolding, or highlights can direct learners to important points or content.

The design of the slides should be guided by principles that enhance learning. This includes minimizing distractions by removing irrelevant materials like excessive animations and sound effects, and ensuring the slides are not overloaded with text. Instead, use graphics and bullet points to organize ideas and highlight key information. This approach makes the slides more digestible and keeps the focus on the core content.

Leveraging the working memory is crucial. Combining spoken words with pictures is more effective than coupling images with text. This combination reduces the cognitive effort required to integrate and understand the material. The use of graphics should complement the information, not overtake it, and visuals should be selected to highlight and reinforce the points being made.

By incorporating these best practices into Transcriptto's slide creation methodology, the tool can generate educational PowerPoint presentations that are not only visually engaging but also pedagogically sound. These principles ensure that the slides produced by Transcriptto facilitate active learning and cater to the diverse needs of online learners in engineering education.
