Ratings

Overall Rating:

Content Quality: 2 stars
Effectiveness: 2 stars
Ease of Use: 4 stars
Reviewed: Jul 23, 2002 by Biology Editorial Board
Overview: This site serves as a general tutorial for frog anatomy. General morphology and male/female morphology, including internal organs are covered. Students are asked to identify specific anatomical structures with immediate feedback. The circulatory system is not included. Students may opt to have the structure in question pointed out with an arrow if assistance is needed. The site includes several tutorials which are immediately graded, and students can submit their answers for statistical analysis. The site also includes Quicktime videos of frog hearts beating in the presence of acetylcholine and epinephrine. Students can record the heart rate with and without these compounds.
Learning Goals: Lean to recognize and name the anatomical parts of a frog
Target Student Population: High School or Introductory College
Prerequisite Knowledge or Skills: Some knolwedge of frog anatomy.
Type of Material: Tutorial
Technical Requirements: Quicktime

Evaluation and Observation

Content Quality

Rating: 2 stars
Strengths:

  • An additional source of practice for students attempting to learn some anatomical structures.
  • If students have latex-injected frogs, they can compare their frogs to unpreserved specimens shown on this site.
  • The functions of organs described in the brower?s status area are a good source of clues to organ names.
Concerns:

  • Quality of images is marginal. In some images, the heart, lung, liver and spleen are all exactly the same shade and may be difficult to distinguish.
  • Does not address the circulatory system or musculature. Only one blood vessel is identified, and it appears to be incorrectly labeled (vessel appears to be the posterior vena cava not the aorta).

Potential Effectiveness as a Teaching Tool

Rating: 2 stars
Strengths:

  • Gives additional practice in identifying some anatomical structures.
  • Questions at the end of the exercise are an effective review and offer immediate feedback.
Concerns:

  • Does not promote critical thinking.
  • Only tests memorization, does not test relationships between organs.
  • Lack of circulatory system coverage limits usefulness.
  • Site could not easily be used for teaching, but could be used for review.
  • To adequately identify the organs pictured, it is necessary to use both organ functions from the browser box and a previous knowledge of general organ location.

Ease of Use for Both Students and Faculty

Rating: 4 stars
Strengths:

  • Simple format
  • Easy to navigate
  • All buttons on the morphology photographs worked easily, including rollover
    functions.
Concerns:

  • Clicking on anatomical structures does not always prompt an answer.
  • Quicktime movies do not always load.
