(1) Mr. Swartz has asked for assistance creating a slideshow presentation on the four stages of cell mitosis for his science class. (2) The presentation should include an intro slide with title, date and teacher, and four slides with graphics and text from the links provided describing each stage. (3) The text for slides 2 and 4, and graphics for slides 3 and 5, should animate on automatically without clicks. Formatting should use appropriate transitions and colors, and text/graphic positioning to effectively communicate to various audiences.

1. PRESENTATION TASK Classroom Context: This performance assessment focuses on a high school science teacher, c, who is preparing a unit on cells. Background: As part of the study on cells, Mr.. Swartz would like to present to his students a brief slide show presentation outlining the four stages of cell mitosis. He would like to have each slide in the presentation advance manually. Mr. Swartz has provided a link to the graphics for the four slides that can be downloaded by clicking on the links below. Available Files: cell1.gif (graphic image for slide #1) http://gemini.utb.edu/jbutler/6343/exam_images/cell1.gif cell2.gif (graphic image for slide #2) http://gemini.utb.edu/jbutler/6343/exam_images/cell2.gif cell3.gif (graphic image for slide #3) http://gemini.utb.edu/jbutler/6343/exam_images/cell3.gif cell4.gif (graphic image for slide #4) http://gemini.utb.edu/jbutler/6343/exam_images/cell4.gif

3. Create slides 2 through 5 using the five files provided by Mrs. Garza. Each slide should contain a title, an appropriate graphic image and text provided displayed as a bulleted list.

4. Animate the entry of the text of slides 2 and 4 (the animations should occur automatically and not require a mouse or keyboard click).

5. Animate the entry of the graphics in slides 3 and 5 (the animations should occur automatically and not require a mouse or keyboard click).

6. Formatting

7. Use appropriate transitions to communicate effectively without distracting from the content of the presentation.

8. Use a color scheme appropriate for audience members including those who may be color-blind.

9. Use the principles of design to format the text and graphics to communicate to the intended audience.

12. Interphase DNA has replicated, but has not formed the condensed structure of chromosome. They remain as loosely coiled chromatin. Nuclear membrane still intact to protect the DNA molecules from undergoing mutation

13. Prophase The DNA molecules progressively shorten and condense by coiling, to form chromosomes. The nuclear membrane and nucleolus are no longer visible The spindle apparatus has migrate to opposite poles of the cell.

14. Metaphase The spindle fibers attach themselves to the centromeres of the chromosomes. The fibers align the chromosomes at the equatorial plate.

15. Anaphase and Telophase The spindle fibers shorten and the centromere splits The chromosomes reach the poles of their respective spindles. Nuclear envelope reform before the chromosomes uncoil. The spindle fibers disintegrate.
