Assignment P4 (Fall 2016)
Due: Sunday, September 25th, 2016, by 11:59PM UTC-12 (Anywhere on Earth). This assignment is based on lessons 2.7 (Task Analysis) and 2.8 (Distributed Cognition).
Answer the following four questions in a maximum of 300 words each (unless stated otherwise); if you supply more than 300 words, the grader will stop reading at the 300th word, and you will not receive credit for anything written after that. Clearly delineate where each answer starts and ends. You are encouraged but not required to complement your responses with diagrams, drawings, pictures, etc.; these do not count against the word limit, though any captions, text in tables, etc. does.
- Create a thorough GOMS model for contacting a professor to ask for explanation of a grade. In doing so, make sure to (a) identify the initial situation, (b) describe the selection rules, (c) outline several methods, (d) identify the operators that comprise those methods, and (e) describe the ultimate goal. Your model should stand on its own; there should be no text supporting the answer to this question.
- Create a hierarchical task analysis of the task of completing this assignment. This task analysis should cover everything from the initial reading of this assignment to receiving the grade. We would expect an adequately sufficient analysis to have at least five top-level tasks and at least three levels of hierarchy. Your model should stand on its own; there should be no text supporting the answer to this question.
- Imagine a time before GPS navigation was as widespread as it is now, and think of the system for navigation comprised by two individuals (a married couple), a map, and any other artifacts the individuals generate. Analyze this system from the perspective of distributed cognition: what cognitive activities, including perception, memory, reasoning, and acting, does each part of the system perform (~175 words)? Then, examine this same situation from the perspective of social cognition. What does social cognition reveal about the situation that distributed cognition does not (~75 words)?
- Distributed cognition is a lens through which we can view HCI. Take any interface you’ve described in a previous assignment for this class and analyze it from the perspective of distributed cognition. First, identify and briefly describe the interface you’ve chosen (~50 words). Then, describe the pieces of the system (~50 words). Then, describe what cognitive tasks are performed by each member of the system, both human and artifact alike (~150 words). The best answers will choose interfaces that touch on multiple cognitive roles in the non-human portions of the system.
Assignments should be submitted to the corresponding assignment on T-Square in accordance with the Assignment Submission Instructions. Most importantly, you should submit a single PDF for each assignment. This PDF will be ported over to Peer Feedback for peer review by your classmates. If your assignment involves things (like videos, working software prototypes, etc.) that cannot be provided in PDF, you should provide them separately (either through the class Resources folder or your own upload destination) and submit a PDF that describes how to access the assignment.
This is an individual assignment. Every student should submit an assignment individually.
Late work is not accepted without advanced agreement except in cases of medical or family emergencies. In the case of an emergency, please contact the Dean of Students.
Each question is graded out of 5 possible points; thus, the assignment as a whole is graded out of 20 possible points. Your grade and feedback will be returned to you via T-Square. An announcement will be made via Piazza when grades are returned.
After submission, your assignment will be ported to Peer Feedback for review by your classmates. Grading is not the primary function of this peer review process; the primary function is simply to give you the opportunity to read and comment on your classmates’ ideas, and receive additional feedback on your own. All grades will come from the graders alone.
You will typically be assigned three classmates to review. Peer reviews are due one week after the due date of the assignment, and count towards your peer review grade. Remember, peer reviews are graded not just based on completion, but also based on feedback quality. Each peer review should be substantive, whether in the way it critiques, praises, or elaborates on the assignment.
