Overview:

Cell Biology/Thermodynamics Lesson topic 1 is one of a series of interactive web-based lesson topics designed to teach fundamentals of thermodynamics as it affects living things. The lesson is a essentially a game to acquaint students with energy budgeting in living organims. It is highly interactive and clearly illustrates the need for animals to manage energy supplies. Thermodynamics (sometimes referred to as energetics) is a difficult process for students to grasp; this site can be used as a supplement to the lecture to allow students to review the topic at their own pace and as many times as desired. The larger site containing the entire series will be very useful at the introductory level

Learning Goals:

The major focus of this lesson is to acquaint students with how organisms manage energy and why it is so essential to contined life. This lesson topic contains specific learning objectives.

Target Student Population:

High school (AP level) through college.

Prerequisite Knowledge or Skills:

Students will need to have a basic understanding of chemistry as it applies to living organisms in order to understand this lesson. Students will also be expected to have read the text assignments on this topic.

Type of Material:

Tutorial.

Recommended Uses:

This site could be used in many ways. 1. As the basis of a classroom lecture presentation. 2. As an out-of-class assignment before the topic is covered in class. 3. As a study tool for students after topic is presented in class.

Technical Requirements:

Use of a current web browser will be required. Macromedia Flash Player 6 plug-in is required.


Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths:

  • Throughout the lesson, the student is required to manipulate objects to get the correct answer before going on.
  • Questions asked throughout lessons help student get feedback on understanding of concepts/process.
  • Animations clearly connect the different parts of each process into a coherent whole.

Concerns:

  • None.


Potential Effectiveness as a Teaching Tool

Rating: 4.7 stars
Strengths:

  • The paramecium energy game is an excellent way to get students thinking about energy and life.
  • Clearly demonstrates relationships between elements of each concept.
  • The site can be used in several ways as a direct teaching tool in a distance learning course, as a lecture outline, as a review and study tool for students after topic covered in class.
  • Some of the questions asked promote problem solving by student.
  • Some of the questions asked will be very challenging for introductory students.
  • Completion of plans for links to assessments and image/animation data bases will greatly enhance the usefulness of the site.

Concerns:

  • None


Ease of Use for Both Students and Faculty

Rating: 4.5 stars
Strengths:

  • Instructions clear, especially when manipulating components and entering animations.
  • Instructors manual available; summarizes the contents of each of the lesson topics.
  • Glossary available for selected terms.

Concerns:

  • None


Other Issues and Comments:

This series of lessons has outstanding potential for use by faculty and students everywhere. The concepts are broken down to simple parts and then reassembled by an interactive process and animations into a whole.
