Overview: This site is an interactive animation on sickle cell, its inheritance pattern, and the services that genetic counselors can provide to those who seek their services. Details about amino acids, DNA replication, proteins, and protein folding are explained with an age-appropriate vocabulary.
Learning Goals: The animation/tutorial uses a case study (sickle cell) to teach DNA, protein synthesis, expression of character trait, and what to do with the information. The animation has embedded assessments that help the learner track his/her progress throughout the learning process.
Target Student Population: Although very basic, this animation could be used for middle school, high school, and for nonscience majors at the college level.
Prerequisite Knowledge or Skills: Basic knowledge of genetics and cell biology.
Type of Material: This is an interactive animation, that contains voice over readings for ADA compliance.
Recommended Uses: This animation would be best be used to integrate DNA replication, transcription, and translation to health and disease. In addition, it would provide a real-life link to a disease that impacts many in society today.
Technical Requirements: Browser with Adobe Flash Player.

Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths:
  • The narrated animation is skillfully presented using vocabulary that is appropriate for beginning biology students
  • Content is accurate based on currently accepted information regarding DNA, sickle cell, and genetic counseling techniques
  • Learners can pause and rewind the learning object for better understanding
  • Assessment questions are embedded in the learning object
Concerns:
  • At first glance it appears to be be useful for elementary grades. However, the content is at a higher level than the animations reveals
