This learning module, although designed for a physics course, would be interesting for a pre-professional student studying a health science discipline that uses x-rays and CAT scans. It is designed as a simulated conversation between "Dr. Bob Hellman", an "intuitive physicist and two teen-aged students. The format is questions and answer. The physics professor explains the physics concepts behind x-rays and CAT scans using interactive java applets.
Einstein's Legacy is one component of a larger collection of learning objects found in the Pedagogical Principles of the Physics 2000 website. The website was conceived by Professor Martin Goldman and developed with grants from the Colorado Commission on Higher Education and the National Science Foundation.
Type of Material:
The material is classified as a presentation.
Recommended Uses:
It can be used to augment lectures and textbook readings. It could be used as a resource for individual and small group assignments.It is a good "eye catcher" for introduction to this technology.
Technical Requirements:
According to the web site the technical requirements include the following:Internet Explorer 4.5 with Apple's MRJ2.1Netscape Navigator 4.7
Identify Major Learning Goals:
The major learning goal is to develop a fundamental understanding about how x-rays and CAT scans work.
Target Student Population:
The target audience includes high school and college students in the beginning physics courses. Pre-professional health science students would also benefit from this learning resource.
Prerequisite Knowledge or Skills:
Prerequisite knowledge includes completion of basic science courses.
Content Quality
Rating:
Strengths:
The strengths include:
Nice visually appealing site with a roll over that demonstrates the view from the cat scan.
Basic writing that is understandable with little technical background
The question and answer format using icons of the characters
The visual appeal of the applets
Easy reading with explanation of advanced concepts in everyday language.
Concerns:
This learning module would benefit with links to other reading resources for more basic and more advanced concepts.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
The learning module is developed using a simple to complex approach. The site map provide navigation.The language, colors, and interactivity make the learning module engaging to use.The illustrations are helpful in understanding more comlex concepts.
Concerns:
This learning module would be improved with the addition of clearly stated learning goals or outcomes.The navigation is not clear on the bottom of each page, for example, not every page has the identical navigation buttons. Most pages have Next and Table of Contents. There are no buttons to rewind to the beginning of the module. Some interactive exercises to help users understand the concept of light and shadows to simulate X-ray and CAT scan would be helpful.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
The information is simple in design for a complex concept
