This was a short video of the peptidoglycan layer of bacterial cell wall.The depiction of the bacteria was wonderful and really highlighted the differences between the peptidoglycan layers
Type of Material:
Microbiology classes before the students learn about gram stain and why the cells look different after gram staining.
Flash player is required to view the video
Identify Major Learning Goals:
To depict all the parts of the peptidoglycan layer and its function in the cell wall of bacteria.
Target Student Population:
Prerequisite Knowledge or Skills:
Biology and understanding the differences between gram positive vs. gram negative.
Evaluation and Observation
Video is accurate and straightforward
The material is clearly laid out
Graphics are of good quality
Great depiction of what the outer membrane looks like
A bit more of an introduction might be helpful to contextualize the material
Wish it showed the nag nam wall and the major differences between gram positive and negative cells.
Also wished they talked about why its important to know the differences between the two different types of gram bacteria
Potential Effectiveness as a Teaching Tool
Promotes conceptual understanding
Appropriate for lower level courses
Nice supplement to lecture material
Showed the flow of the cell and where the peptidoglycan layer was located. Would be great to show before a lab on gram staining or during a talk about the cell wall but would have to talk about other parts of the cell as well (nag nam ect.)
Wished it was longer and talked about all the parts of the cell membrane also wished it compared gram neg to gram positive in a little more depth.
Ease of Use for Both Students and Faculty
Found no defective links or major bugs.
Animations loaded quickly and ran smoothly
Easy to control animation to allow for teaching points and discussion
