Communicate Information

Communicate information in different formats and for diverse audiences.

Communicating in different formats and for diverse audiences is truly what I did all this year in TATC. Sometimes I felt I was speaking Greek and all the answers to my questions were spoken in languages I did not comprehend! My pathway led through unknown lands where the inhabitants spoke in foreign tongues, but it is amazing how much I was able to understand and communicate once I put my mind to it. The tools and knowledge I have gained on different file types and formats and new methods of presenting information this year will come in handy as I continue to travel in the sometimes "foreign" land of technology! I think my students will reap the benefits of having information presented in ways that are not just confined to reading text from a dull handout. They should enjoy and learn more from lessons that can be communicated through web sites, PowerPoint presentations, and maybe even video presentations! True communication is a two-way street where the recipient "understands" the message and there is an interchange of information, and learning usually accompanies this exchange closely. My communication on this level has been enhanced by the wonders of technology, and I hope to continue to use it to great advantage in the classroom.

Artifact #4

Descriptors: Internet searches, compare and constrast types of image file formats, lossless/lossy compression, bitmapped and vector images, elements and principles of design, PowerPoint slideshow

Title: Image File Formats

Course: Digital Graphics 101-1

Date Created: October 15, 2002

Source: Individual TATC project

Media: Information from course readings and Internet searches, presented as a Microsoft PowerPoint show, images were gathered from clip art and pictures from Internet sources, some images were cropped or enhanced in Adobe Photoshop 7.

Description: As part of our coursework to learn more about digital image formats, we were asked to research and communicate our thoughts on the subject to our fellow classmates. We were to share information and compare different image file types such as .gif, .jpg, .tiff, and .png files. A comparison of "lossless" versus "lossy" file compressions was also included, as well as "vector" and "bitmapped" image types. In addition, we were to demonstrate knowledge of the principles and elements of design through our presentation. Using our course readings and Internet sources, I became much more familiar with these previously foreign terms. I searched out and selected images of the various file types to include as examples. The knowledge I gained was communicated to my classmates through my presentation which included information, examples, and a table for easy comparison of file features. A list of sites from which source information had been gathered was also included in the show for easy reference.

Rationale: I chose to include this artifact because it represented my first attempt at using a PowerPoint slideshow for communication purposes, and I was pleased with the results of my attempt. I now have a new technology tool to use in communicating with my students! Researching different image file formats for this project made me much more aware of the functions and limitations of different digital graphic image formats. I became more proficient in the terms related to image files and the considerations one must make to appropriately and successfully incorporate files for various uses. I now know more about the benefits and drawbacks of "lossy" compression for images that will be shared from the web. The greatest benefit of lossy compression is a drastic reduction in file size. A notable drawback is the loss of quality that can occur. There is a degradation of quality in the original image each time the image is saved. This new understanding underscores the importance of saving in other formats for master copies. Through research and synthesis of image file format data, I gained a better comprehension of the types and their specific uses. I then created a multimedia slideshow to communicate this information to others. The knowledge and comparisons of image formats carries over into well designed technology products including desktop publishing items, web pages, digital graphic and animation projects, and multimedia products for my classroom and personal use.

Implications for future: After this initial success, I created another simple slideshow using the software for use in my 4th and 5th grade music class. As I learn more of the features of the software, I plan to become more creative in my presentations. In teaching the Career Investigations class next year, I plan to implement slideshows into my classroom communication. Hopefully, through planned time in our computer lab, the students will also be able to use the technology to present career information to their classmates.

Reviewer's Comments: This worked fine. Good presentation with clear comparisons and good examples.
