Construction of the Cell Membrane

 

Ratings

Overall Rating:

5 stars
Content Quality: 5 stars
Effectiveness: 5 stars
Ease of Use: 5 stars
Reviewed: Nov 14, 2004 by Health Sciences
Overview: This learning object is an interactive tutorial and quizing lesson in the
composition of cell membrane structure. The student studies the structure of the
cell membrane by constructing it using the correct molecules.It is presented in
Flash format; the lesson is engaging, easy to follow, and offers immediate
feedback.
Learning Goals: Through building the molecular structure of the cell membrane, the student
will
learn the makeup and the basis for cell membrane function, as well as identify
and locate teh membrane porteins of a cell wall. This is a crucial
step to learning about the fundamental unit of life -- the cell.
Target Student Population: Students in advanced high school Biology and college basic biology and
physiology courses, as well as students enrolled in health science courses such
as nutrition, pathophysiology,and pharmacology.
Prerequisite Knowledge or Skills: Knowledge of basic physiology terms would make the material more
meaningful to the student.
Type of Material: The presentation is an animation using Flash.
Recommended Uses: This material would match the learning style needs of the visual and
kinesthetic learner to understand the basic core knowledge of an introductory
biology course.
Technical Requirements: The Flash plug-in is required. The site provides a link to the plug-in as
well as a help link.

Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths: Essential components of the membrane structure are presented. This should
provide the learner with a foundation upon which cell function can build.The
animation is very good and the site has an easy linear navigation. The concepts
presented aer clear and concise.
Concerns:

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths: This is a very effective teaching tool because it allows the user to
progress through the screens at the user's pace, allows for going to previous
screens, and gives immediate feedback to questions.The information is core
material for any biology student.
Concerns:

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths: Very easy. The movie could be projected so that the class could guide the
teacher in selecting "answers" -- particularly in the high school setting.
Assuming that college campuses have adequate computing facilities for students,
this would be a good review assignment.
Concerns:

Other Issues and Comments: The site is extremely useful for the student learning about cell wall
construction. A difficult topic is simplified.
