Cardiovascular Embryology Animations

by Valerie O'Loughlin
 

Ratings

Overall Rating:

5 stars
Content Quality: 5 stars
Effectiveness: 5 stars
Ease of Use: 5 stars
Reviewed: May 10, 2002 by Health Sciences
Overview: This site contains 7 short animations of the embryonic cardiovascular system and
its development. The last, newly added animation contrasts the fetal
circulation with the neonatal. Each animation is well labeled, isolating
specific changes over time and from one axis. Key developments are shown from 2
views. Blood flow patterns are clearly shown and anatomical changes dynamically
illustrated as the heart chambers evolve from the primitive heart tube. The
mechanism for change, pressure gradients is addressed.
Learning Goals: The principal goal is knowledge acquisition of structural and functional change
in fetal heart development from the earliest heart tube to the postnatal, fully
developed heart and circulation. The well-conceived and executed animations
achieve this purpose admirably.
Target Student Population: Undergraduate anatomy class
Prerequisite Knowledge or Skills: A minimal knowledge of the circulatory system. The unit is self-contained.
Type of Material: These are animations.
Recommended Uses: The animations can be used in tutorial or class settings. They could be used
for independent study and review.
Technical Requirements: QuickTime and Macromedia Flash plug-ins are required, but are standard to many
systems. Downloading icons are supplied at the bottoms of the pages.

Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths: Well designed, clean interface, ease of use, clear labeling of features, Within
each animation, a great pedagogy is shown. The authors have thought out the
views and perspectives and executed the animations to maximize the learning.
They accomplish what no textbook illustrations could. A clear story is told.
Concerns: The date of development and up-dating might be added to the credits. Text might
be added to specify the icons are downloading instructions. An audio tack might
prove useful, particularly in the fetal/postnatal animation in which the text
is on the smallish side. A reference list could be added.

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths: The color coding, flow arrows, repetition of key points, summary sections all
add the strong pedagogy. Assignment and test questions could be written for the
material.
Concerns: The date of development and up-dating might be added to the credits. Text might
be added to specify the icons are downloading instructions. An audio tack might
prove useful, particularly in the fetal/postnatal animation in which the text
is on the smallish side. A reference list could be added.
