Students often get confused and bored during lectures. With the help of technology instructors can hold students’ attention both inside and outside of the classroom with engaging videos. Here are 5 lecture capture devices that can help make instructors videos more engaging:
Dynamic Green Screen:
- Recording a presentation while the professor is standing in front of a whiteboard or projector can make it difficult for students to see the presentation clearly. Chromatte is a dynamic green screen which is made from a ring of LEDs that go around the camera lens. These lights can shine green or blue on the Chromatte to change the color of the background in the video. The different color helps distinguish the presentation material clearly.
Virtual Green Screen:
- Personify is a software that inserts a video of the instructor into a PowerPoint or other online material. You will need a 3D camera, similar to an ordinary webcam, mounted on the computer. Next, the instructor will record himself with the 3D camera, and Personify automatically filters out the background so the instructor appears in front of the presentation material in the video similar to filming himself in front of a green screen. This is an easy way to insert an instructor into a learning presentation.
- Instructors often have to turn their backs on students while writing on the board, blocking the students’ view of the content on the board. The Lightboard is an illuminated 4-by-8-foot sheet of glass, which allows an instructor to write on the glass from behind using fluorescent markers, so the writing “glows” in front of the person. This helps students see what the instructor is talking about while writing rather than seeing somebody’s back write on the board. On camera the writing appears reverse, but can be digitally flipped or recorded with a mirror. The Lightboard itself costs about $2,000 for the glass frame.
Multi-Perspective Video Capture:
- Mediasite MultiView is a great multi-perspective video capture tool that records both the instructor and the presentation material. While Chromatte, Personify and Lightboard produce a video where the instructor and presentation materials appear in the same view, Mediasite MultiView captures multiple video streams and allows students to view them side-by-side simultaneously or zoom in on one or the other.
- This is an excellent tool for people with disabilities. For example, a student with disabilities can see an interpreter using sign language in one screen while watching the instructor’s PowerPoint slides displayed on another screen. With the help of technology students with disabilities can even zoom in to the singing to receive a closer look.
- Instructors often don’t know if students actually understood their video lectures or if the students even watched them. With the help of eduCanon instructors can use this free tool to embed questions into online videos to create interactive lessons. As a student watches a video, it pauses wherever the instructor has embedded a question and students can’t continue watching the video until they answer the question. EduCanon helps teachers comprehend if their students understood the lecture.
