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.
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.
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.
The Flash plug-in is required. The site provides a link to the plug-in as well as a help link.
Evaluation and Observation
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.
Potential Effectiveness as a Teaching Tool
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.
Ease of Use for Both Students and Faculty
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.
Other Issues and Comments:
The site is extremely useful for the student learning about cell wall construction. A difficult topic is simplified.
