“Muscle Contraction” is a video animation that is part of a larger site, Sumanas, Inc., Molecular Biology collection. This animation describes the mechanism of a muscle contraction beginning with the muscle receiving the action potential from a nerve, to the molecular proteins involved in the contraction. The animation is two minutes in length, and uses narration to describe the process of muscle contraction.
Type of Material:
This animation could be used during a lecture to demonstrate the mechanism of how a muscle contracts. It could also be assigned before a lecture for students to preview as in a flipped classroom. It could also be posted for review to supplement a lecture.
This animation can be viewed with Adobe Flash plug-in or on an iOS device.
Identify Major Learning Goals:
Users will learn the steps involved in muscle contraction beginning with the stimulation from a neuron.
Users will learn the parts of a muscle fiber and the roles they play in contraction.
Target Student Population:
High school students or college students.
Prerequisite Knowledge or Skills:
Prerequisite knowledge is not required, but an understanding of the molecular proteins involved in a muscle contraction would be useful.
The content presented in the animation is accurate.
The animation quickly summarizes a difficult concept and presents it in a clear manner.
The animation provides a foundational understanding of the mechanism of a muscle contraction.
It would be helpful to includ the binding of acetylcholine to muscle cells when the nerve stimulates the muscle
Potential Effectiveness as a Teaching Tool
The animation uses both video and audio to engage multiple senses.
The animation is well designed.
No objectives were listed on the site.
Having text available as an option for a learner to read through would benefit the animation.
Providing review questions at the end of the animation to allow the learner to gage their knowledge would benefit the animation.
Including a glossary of terms or definitions would help learners who were unfamiliar with the different molecular proteins.
Interactivity is limited within the animation. The learner has the ability to rewind or stop the animation, but no other features are included.
Ease of Use for Both Students and Faculty
easy to use
very intuitive, just click play
Other Issues and Comments:
A quick informative animation that supplements textbook and lecture.
