Video of myosin V movement along actin

 

Ratings

Overall Rating:

4.7 stars
Content Quality: 4 stars
Effectiveness: 5 stars
Ease of Use: 5 stars
Reviewed: Jan 16, 2003 by Biology Editorial Board
Overview: This is a wonderful (if somewhat grainy) video of the movement of actin and
myosin that can be found under ?Myosin News?. The video is part of a much
greater site on myosin with a huge amount of information available covering the
molecular, physiological and anatomical research on myosin. The movie does not
come with any information other than the title, but to get to the movie you have to click on the link that also includes a link to the research that has been
done on myosin.
Learning Goals: To observe the interaction of actin and myosin
Target Student Population: College, med school, graduate
Prerequisite Knowledge or Skills: The viewer needs to know what is actually happening to understand the
interactions that are occuring.
Type of Material: Video
Interactive Lesson/Tutorial
Recommended Uses: Great addition to a section on actin/myosin interactions to see it 'live'
Technical Requirements: Netscape 4.7
Quicktime

Evaluation and Observation

Content Quality

Rating: 4 stars
Strengths:

  • The material is clearly laid out, accurate and integrates content well.
  • This video is part of an excellent and detailed site on myosin
  • The video itself is amazingly clear and would be excellent to show students how
    these molecules interact.
Concerns:

  • The user would want to make sure that they had some additional information for the students who are viewing the movie as it plays with no explanation of what
    if going on. However, the site has all the information about the movie in other
    sections.

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths:

  • Links are excellent
  • Provide a good range of information to aid student understanding
  • The rest of the site is an amazing source of information on the current research in this field
Concerns: None

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths:

  • The links are all complete and so the site is easy to navigate
Concerns:

  • The ability to make the image larger would be an asset

Other Issues and Comments: This is a grainy video clip showing actin and myosin interacting. It is not for the beginner biologist (nor the nonmajor) as it does not really cover the
basics of this interaction nor does it have any labels to indicate what the
images actually are. This site is great for advanced students, graduate or
professional.
