Ratings

Overall Rating:

4.75 stars
Content Quality: 4.75 stars
Effectiveness: 4.5 stars
Ease of Use: 5 stars
Reviewed: Feb 02, 2014 by Biology Editorial Board
Overview: The website provides a narrated animation describing the process of protein trafficing through the Golgi apparatus. The viewer can play the movie within the webpage or download it. It is also possible to download a text version of the narrative. A protein is transferred through a sequence of membrane structures. The Golgi apparatus is one structure involved in sorting and transferring proteins manufactured in a cell. This animation gives an overview of the processes involved in protein trafficking to and within the Golgi.
Learning Goals: No specific learning outcomes are listed but the animation clearly illustrates protein transport. It connects well with a similar object on Protein Modification. Through use of this site, students will acquire a basic understanding of protein trafficking through the Golgi.
Target Student Population: This material could be used in Middle School, High School, College General Education, and College Lower Division courses.
Prerequisite Knowledge or Skills: Users will need a basic understanding of cell structure as well as vverall knowledge of molecular cellular processes to place these details in an overall framework.
Type of Material: Materials at this site are presented as a Flash movie animation.
Recommended Uses: This object could be used to augment a class presentation as a pre-class assignment, or as a review.
Technical Requirements: This learning object requires a web browser equipped with the Flash plugin.

Evaluation and Observation

Content Quality

Rating: 4.75 stars
Strengths:
  • The strength of this site resides in that it is a clear summary of the important concepts, the quality of the animation, and that it is applicable for use in basic biology courses at a number of levels
  • Animation is clear and easy to follow
  • Narration is appropriate for the information presented and matches the action in the animation
  • Information is accurate and demonstrates how the Golgi fits into the overall process of protein movement to the correct spot in the cell
Concerns:
  • There were no concerns about content quality at the time of this review

Potential Effectiveness as a Teaching Tool

Rating: 4.5 stars
Strengths:
  • Would work well as as an adjunct to classroom presentation
  • Could be used as an assignment prior to class
  • The video could be easily integrated into a lecture or linked to online course material
  • Will make a good review
  • Students can play animation multiple times until they are comfortable that they can explain the process
Concerns:
  • Some simplification should be done to make presentation clear
  • Student needs to know place of process in overall cellular activity

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths:
  • The authors have made this animation extremely easy to use by providing the option to play the video directly on the website or download it
  • Very easy to use
  • Transcript of narration provided for reference and can be printed
Concerns:
  • There were no concerns about ease of use at the time of this review

Other Issues and Comments: The purpose is to break the cellular various process into small chunks of information and explain each with a short animation. There are advantages to that approach. The disadvantage is that the student may have difficulty seeing the process as a whole.
