This narrated animation depicts the location of transport proteins in relation to the plasma membrane and describes how materials are carried across the membrane by these different protein carriers. The processes by which uniport, symport, and antiport protein transporters carry out the process are briefly described.
Type of Material:
Narrated animation
Recommended Uses:
• In-class lecture supplement
• homework
Technical Requirements:
Flash player
Identify Major Learning Goals:
• User will learn of the different types of proteins that transport materials across the plasma membrane
• User will learn the classification of transport proteins based on the direction with which solute is moved across the membrane
Target Student Population:
High School, College General Ed, College Lower Division
Prerequisite Knowledge or Skills:
Transport across membranes.
Content Quality
Rating:
Strengths:
• Illustration and animation clearly depicts the object being described, in this case the different types of membrane transport proteins and the mechanism with which each type carry out its function.
• Narration is clear and concise.
• Clearly distinguishes between different forms of facilitated diffusion. • Easy to view without complex text or descriptions.
Concerns:
• It would have been more accurate if the energy requirements needed to operate these transport proteins is addressed in the narration and animation.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
• Narration helps students understand the relatedness of the topics as depicted in the animation, in this case the location of transport proteins relative to the plasma membrane.
• Narration helps user focus on key concept, in this case the process with which each type of transport protein carries out its function.
• Graphics and animation provide a visual and auditory enhancement for visual and auditory learners.
• Could create assignments based on the animation.
• Illustrates differences clearly without need for text.
Concerns:
• Addressing the energy expenditure required to operate these transporters would have added accuracy to the learning object.
• No assignments or suggested uses are provided.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
• Narrations and animations played simultaneously without problems.
• Information is easy to understand.
• Loads easily and runs smoothly.
• Quality graphics and narration.
Concerns:
• No closed caption.
