The Internet -- Interactive multimedia programs are transmitted over the internet. As long as the proper connection and appropriate software is installed, any computer can access words (text), pictures (images), and sound over the internet -- it no longer matters whether a PC or Mac is used. The internet is accessed through software programs known as a "browsers." Many good browsers are currently widely available: MS Explorer, Netscape, Apple's Safari, and Mozilla's Fire Fox are examples.


 

 
 
 

Linkage of Course Materials -- An important advantage of the internet is the ease with which links to information can be created. This Web course heavily relies on such links. Links can be identified by passing the arrow cursor over text or images and noting if the arrow changes to a hand. Often, links are indicated by underlined text with vertical bars (e.g., | Link | ). By clicking on links, related materials will appear on the screen. An example of underlined links is the outline at the top of this page: clicking on a linked phrase will show the linked text instantaneously. You will note that as the underlined text is clicked, it changes color indicating that the link has been activated. The linked text changes to yet another color upon return to let you know that that link has been "visited." The visitation color remains for a few days then returns to the normal inactivated linked color. These color changes usually do not occur with non-underlined links. The index pages in this site make use of non-underlined links; cursor change will locate these links.


 

 
 
 

Site Contents -- This site contains all learning materials needed for successful completion of PTHL 312abc.

The reader is presented as a text-book-like photocopied document. Computer-rendered (PDF) versions of the chapters are included in the site so that students can replace lost printed versions without time loss.

Learning guides are printed documents designed to structure independent learning sessions. Like the reader, these are also available in PDF format.

Image cards are important features of this site. These "cards" consist of text and images arranged on the computer screen in a consistent way. There is an introductory card for each disease followed by variable numbers of subsidiary cards. All cards, whether introductory of subsidiary, display text on the left side and a related image(s) on the right.

Thumbnail cards provide an overview of the images assembled for each disease. In addition to the text review, they have up to twelve photographs (images) of the important clinical and microscopic features. Because these images are small they are known as "thumbnail images" or, simply, "thumbnails." By viewing the thumbnails, the student can, at a glance, see all the images that are assembled for a disease. By clicking on one of the thumbnail images, the student will be taken to a subsidiary card for the disease under study.


 

Baseball cards feature a single image with a pertinent description of it. On the left is a description of the image found on the right. (Because these subsidiary cards combine text and image, they reminded some of baseball cards which, of course, have a picture of the baseball player and text describing features pertinent to the player.) If the image is clicked, the screen will be taken over by an even larger one. There are, then, three magnifications of each image: (1) the thumbnail image on the thumbnail card, (2) the intermediate image on the baseball card, and (3) the large screen-filling image.

Study questions are can be accessed from the course index page (e.g., PTHL 312a image page). These are arranged by reader chapter. The questions located at end of each printed reader chapter are found here; others were taken from recent examinations. By clicking on a choice, the answer accompanied by explanatory text will appear in a nearby frame. Both correct and incorrect answers appear with appropriate explanatory comments.

Definition "flash cards" can be accessed from the course index page (e.g., PTHL 312a). These contain terms and associated definitions. Another set contains definitions and associated terms. In the first set, students will view terms and test themselves on the related definitions. In the second set, students will view definitions and test themselves on related terms.
