Using Different types of Video to Enhance Learning

Different modalities of video content can be tailored to specific learning objectives, audience needs, and subject matter. Understanding these modalities is crucial for instructors aiming to maximize the effectiveness of their online courses. This article briefly explores five different modalities of educational video content: video lecture, video podcasts, whiteboard, screen recordings, field videos, and 3D models. Each modality serves a unique purpose and can be strategically used to enhance the learning experience.

Video Lecture (top)

This modality typically involves slides created using software like PowerPoint or Google Slides, which are narrated by the instructor. The content is organized in a linear, sequential format, making it easy for students to follow.

Key Features:

• Structured Content: Information is presented in a structured and organized manner.
• Narration: The instructor narrates over the slides, either using a script or ad-libbing.
• Linear Learning: Content is presented in a linear sequence, which is beneficial for foundational knowledge.

Video Podcast (top)

This modality involves a discussion between two or more individuals with similar domain expertise. It can also take the form of a mentor-apprentice dialogue, where one person with extensive knowledge in a particular area guides another.

Key Features:

• Near Peer Expertise: Participants have similar levels of prior knowledge, allowing for meaningful and relaxed discussions.
• Ad-libbing: Conversations are often spontaneous, drawing on personal experiences and expertise.
• Information Density: Discussions are rich in information, providing deep insights into the topic.

Whiteboard + Instructor (top)

This modality focuses on explaining complex concepts and ideas through visual aids and informal instruction. It involves an expert guiding learners through a progressive disclosure of a diagram or visual, drawing and explaining each component over time. Typically they are on camera off to the side.

Key Features:

• Visual Explanation: The instructor creates and explains diagrams or visuals on a whiteboard, making abstract concepts more tangible. In a conversational tone, making the content feel approachable and easy to understand.
• Progressive Disclosure: Complex ideas are broken down and revealed step-by-step, allowing learners to follow the instructor's thought process. The expert csn gradually build a complex visual, explaining each element as they draw it.
• Reusable Components: Simple paper or magnet icons can be used for common elements, helping to create a consistent look and feel across multiple whiteboard explainers.

Screen Recording (top)

This modality focuses on transferring knowledge about how to use specific software tools. It involves an expert guiding learners through a sequence of steps to complete a task within the software.

Key Features:

• Step-by-Step Guidance: The expert narrates each step, explaining what they are doing and why.
• Clear Instructions: The expert clearly states where they are navigating and what actions they are taking.
• Practical Learning: Learners watch the expert's actions on screen, such as mouse movements and keyboard inputs.

Field Video (top)

This modality captures learning experiences from job sites, particularly relevant in fields like renewable energy. It can be filmed using smartphones, drones, 360-degree cameras, or VR setups.

Key Features:

• On-Site Learning: Experts film aspects of their job site, explaining what they are looking at and why it matters.
• Practical Insights: The video often includes someone pointing out systems, subsystems, and components, explaining their relationships and highlighting trouble spots.
• Expertise: Skilled practitioners share their expertise, providing insights that might not be understood in an office setting.

3D Models (top)

This modality involves an expert explaining and narrating over a 3D model of a component or system. It allows for manipulation of the object, such as panning, zooming, and turning on data labels.

• Key Features:
  • Interactive Learning: The expert can animate the object, zoom in, and pan to explain different parts.
  • Detailed Explanations: The 3D model can be used to explain complex systems, such as CAD models for solar PV systems or heat pump schematics.
  • Controlled Environment: Unlike field recordings, 3D models offer more control over the learning environment, making it easier to focus on specific details.

Choosing the right modality for educational video content depends on the learning objectives, the nature of the subject matter, and the audience's prior knowledge. Video presentations are ideal for foundational knowledge and linear learning paths. Video podcasts are best suited for discussions that require near-peer expertise and ad-libbing, offering a relaxed yet informative approach. Screen recordings are perfect for teaching software skills and step-by-step processes. Field videos are invaluable for practical, on-site learning experiences, especially in fields like renewable energy. 3D models are excellent for explaining complex systems and components in a controlled and interactive environment. By understanding and strategically employing these modalities, instructors can create an engaging learning environment that leverages each of their respective strengths to create a unique mix to enhance learning.
