Ease of Use:

Overview:: This is a short video of a neutrophil chasing and phagocytizing a bacterium taken from a 1950's film. It is a simple and straighforward YouTube video that can be used in the classroom or at home
Type of Material:: This material is presented as a simple YouTube video.
Recommended Uses:: This is a short video (less than 30 seconds) without narration; it is best suited for use in class so teacher can describe what is happening.
Technical Requirements:: Technical requirements include an Internet browser such as Chrome or Firefox that can be used to view the YouTube video.
Identify Major Learning Goals:: Major learning goals include better understanding of chemotaxis and phagocytosis at a cellular level, using the example of a neutrophil chasing and then engulfing a bacterium in the blood.
Target Student Population:: The target population includes students in Middle School, High School, College General Education, and College Lower Division
Prerequisite Knowledge or Skills:: Students will need to know what chemotaxis and phagocytosis are in a general sense, because the video does not give any description or explanation beyond the title.

Content Quality

Rating:

Strengths:

Video shows actual cell movement and behavior
Clearly shows the movement of neutriphil cell
Bacterium easily identified
Demonstrates an important concept in microbiology and immunology

Concerns:

This learning object does not contain narration or a written description of what is happening in the video. Students may need further explanation.

Potential Effectiveness as a Teaching Tool

Rating:

Strengths:

The video can be used in a variety of applications to illustrate cell behavior and chemotaxis
While specific objectives are not specifically identified the video is clear and would be useful for several application inside and outside of the classroom
Students can easily see movements of the leading edge of the cell
Material is easy to show in class and integrate into activities or assignments

Concerns:

There are no learning outcomes or prerequisites identified, nor is there progressive reinforcement of concepts unless a teacher uses this video to reinforce concepts taught in lecture or follows the video with a discussion of concepts.

Ease of Use for Both Students and Faculty

Rating:

Strengths:

This is a YouTube video that is familiar to students
Very straighforward and easy-to-use video in the classroom

Concerns:

There are no audio component for students with vision impairments, nor is there a written component that can be read by a screen reader. Not particularly interactive.

Other Issues and Comments:: This same video is available on YouTube with a voice over narration and written description, which is much better for students.
