1. Simplicity and Consistency To make communication clear and precise (Thorsen, C., 2009).

2. Basic Interface Design Principles of learning -- Students learn better when: Words and pictures are presented, simultaneously in close proximity http://www.celldiagram.net/plant-cell-diagram.html (Thorsen, C., 2009).

3. Basic Interface Design Principles of learning -- Students learn better when: Animation and narration are used with no extraneous words or on-screen text. http://www.youtube.com/watch?v=VlN7K1-9QB0 (Thorsen, C., 2009).

4. Basic Interface Design Orient users so they know where they are in the presentation Use Headings and Captions Be consistent in layout Simplify the structure http://www.mhhe.com/biosci/genbio/tlw3/virtual_labs/lab1/labs/lab1/home.html (Thorsen, C., 2009).

5. Limit text styles three maximum Basic Interface Design Always use sans-serif fonts for your Web page main copy. Arial Geneva Helvetica Lucida Sans Trebuchet Verdana Use monospace to provide instructions Courier Courier New Lucida Console Monaco Use fantasy/cursive fonts in images, headlines or call-outs. Copperplate Desdemona Impact Kino (Thorsen, C., 2009).

6. Justify text appropriately Left justify text Right-justify or decimal-justify numbers Basic Interface Design Keep text lines short Use lists Bullets Numbers Check boxes (Thorsen, C., 2009).

7. Basic Interface Design Use upper- and lower- case letters Use single spacing Double space between paragraphs Do not use flashing text Do not stack text—use horizontal (Thorsen, C., 2009).

8. Basic Interface Design Use a color scheme Limit colors -- three maximum http://www.biology.arizona.edu/biochemistry/tutorials/chemistry/ main.html http://www.biology.arizona.edu/biochemistry/problem_sets/ph otosynthesis_2/photosynthesis_2.html (Thorsen, C., 2009).

9. Basic Interface Design Limit the focus One main topic per screen Five to nine subtopics Provide Emphasis Use bold, italics or underlining http://www.biology.arizona.edu/cell_bio/tutorials/cell_cyc le/main.html (Thorsen, C., 2009).

10. Basic Interface Design Enhance text with graphics and interactivity http://www.hhmi.org/biointeractive/click/index.html (Thorsen, C., 2009).

11. Basic Interface Design Know your audience!! (Thorsen, C., 2009).
