Transcript of "CCC FDW FA2011"

  1. 1. Cell models: a virtual scavenger hunt Presented by May Coulson Adjunct faculty, City colleges of Chicago Aug 9, 2011
  2. 2. An idea takes shape <ul><li>Initially in my traditional f2f course, students were given an assignment to come up with a cell model art project </li></ul><ul><li>Students learned the cell parts, as well as public speaking skills, since their models were orally presented to the class </li></ul>
  3. 3. My “cell” collection <ul><li>Clearly this needed adjustments in the online course </li></ul>
  4. 4. Cell models <ul><li>Students are divided into 3 separate groups to work on either a prokaryotic, animal or plant cell </li></ul>
  5. 5. Cell models <ul><li>They use the group discussion board of Blackboard (BB)to work on their project </li></ul><ul><li>A single final report is submitted by the group to an open discussion board </li></ul>
  6. 6. Cell models <ul><li>Students are asked to look for images that either structurally resemble parts of a cell </li></ul><ul><li>Or they can look for images that describe visually the function of the cell parts or organelles </li></ul>
  7. 7. How to post images using BB discussion board <ul><li>http://www.screencast.com/users/MCoulson/folders/Default/media/7fcfb8c5-5284-4563-80d8-1bac90acfeaf </li></ul>
  8. 8. Cell models <ul><li>The final report must include a rational as to why they chose their particular image, does the image represent a structural similarity or a functional one </li></ul>
  9. 9. Cell models <ul><li>students are encouraged to view each groups submissions and give feedback </li></ul><ul><li>A scoring rubric is included to account for students individual participation as well as group participation </li></ul><ul><li>Creativity and imagination are part of the scoring rubric </li></ul>
  10. 10. Rubrics: individual participation Evaluation criteria Proficient Adequate Not there at all Evidence of critical thinking Provides superior documentation of the relevance of image to a component of the cell type. Clear evidence is demonstrated of the relationship of each cell component to the cell type (4pts) Description of image relates somewhat to cell components and/or cell type (3pts) Does not provide documentation of relevance of image to cell type or cell component(0pts) Ideas Demonstrates use of creativity and imagination (4pts) Some evidence of creativity and imagination is present (3pts) Creativity and imagination not present (0 pts) Appropriate web links and timeliness Finds relevant and correct web sites (URL) and completed by deadline (2pts) Web sites and links are somewhat relevant (1pt) Does not provide web link (URL) and not completed by deadline (0pts)        
  11. 11. Rubrics: group participation Evaluation criteria Proficient Adequate Not there at all Evidence of collaboration in group Actively participates in group and collaborates with fellow group members (3pts) Minimal participation, collaborates with fellow group members occasionally (2pts) No interaction with fellow group members (0pts) Frequency of group interactions Frequent logins and group postings (2pts) Minimal logins and group postings (1pt) No logins and no group postings (0pts)                
  12. 12. Student examples <ul><li>This picture of the Pentagon represents the cell’s Nucleus, because if the military would be a cell than Pentagon would be its Nucleus.  The many guarded doors to the Pentagon building represent the nuclear pores, the officers sent by Pentagon to the field represent the ribosomes and the messenger RNA is represented by orders that the officers are carrying out. The two outer layers of the building represent the two membranes of the nuclear envelope. From the air pentagons shape somewhat resembles the Nucleus. </li></ul>
  13. 13. Student examples <ul><li>This picture of the shipping depot (like Peapod company )represents the Golgi apparatus. The picture that shows the goods being sorted, packaged , loaded on the trucks and sent to customers represents how the Golgi sorts, repackages and sends proteins in vesicles  all over the cell. </li></ul>
  14. 14. Student examples <ul><li>These toothbrush bristles represent the cilia.  Cilia are short hair like extensions from the cell moves with a back-and-forth motion. Like in the respiratory tract they sweep debris trapped in mucus away from the lungs. In the case of the toothbrush bristles, they move back and forth when moved across the teeth. </li></ul>
  15. 15. Student examples <ul><li>This solar powered mobile home represents the mitochondria.  This futuristic mobile home takes the energy from outside and transforms it into a different form of energy to support its inhabitants, just like the mitochondria which produces energy to support the life of the cell.  This futuristic mobile home with its rounded bean-like design also looks similarly to mitochondria. </li></ul>
  16. 16. Outcomes and benefits <ul><li>Students perform better on the unit exam </li></ul><ul><li>Cell structure and function are more clearly understood since students find images that have more relevant meaning to them </li></ul><ul><li>Students learn to collaborate </li></ul><ul><li>Students are teaching each other (peer learning) </li></ul>
