Evaluation and Observation

Content Quality

Rating: 3.75 stars
Strengths:
  • This web page gives a good overview of the four macromolecules.
  • The authors does a good job of making it relevant by looking at a meal that most students will be familiar with.
  • There are links to a couple of key terms that bring up a definition or explanation in a new window.
    Concerns:
    • Heavy on the text.
    • Need to use formatting more to emphasize certain aspects of the text that require the students focus.
    • It would be helpful to have more links to words and phrases that need definitions, especially in the first few paragraphs talking about chemistry concepts.

      Potential Effectiveness as a Teaching Tool

      Rating: 3.75 stars
      Strengths:
      • This page would work well for a homework assignment or review.
      • A good set of questions will help students, especially if they work together to make sure the answers are correct or if they have time to confirm the answers through the instructor.
      • The information is presented in a manner that is easy to understand
      • Review questions at the end of each lesson enhances the usefulness of the material
        Concerns:
        • Pages are static text
        • Text-based information may not help students that have difficulty getting the information out of the textbook

        Ease of Use for Both Students and Faculty

        Rating: 4 stars
        Strengths:
        • The webpage is very easy to navigate and follow.
        • Text-based presentation gives access to the material to any student using any of the commonly used browsers.
        • It will be a good reference for students who may be struggling with the concept of organic molecules especially at the start of the semester.
          Concerns:
          • The regular 12 point Times New Roman font against an orange background is difficult to look at for long time periods
          • For someone who may have some visual impairment, the site is not ADA compliant.

          Other Issues and Comments: The simplicity and the direct approach of this "lecture" material will be helpful especially for students who are getting ready to take a test.
