Course Objectives and Summary
- UA On-line catalog description for Geos. 220: Environmental and cultural history of the Southwest emphasizing discovery of the past using historical science techniques of tree-ring and packrat midden analyses and repeat photography.
- This course will cover several paleoenvironmental tools that have been involved extensively in reconstructing the natural and cultural history of the Southwest (as well as for other regions, too). They include:
- Tree rings
- Packrat middens
- Alluvial stratigraphy
- Repeat photography
- Historical documents
- Whereas the overall scope of this course encompasses broad time scales, its focus increases in detail as it moves from the distant to the recent past.
- Spatially, the greater Southwest includes most of Arizona and New Mexico as well as southeastern Utah, southwestern Colorado, and northern Mexico.
- This course has been described in detail in an article published in 2008 in the Journal of Geoscience Education. Click here to see it.
Expected Learning Outcomes
- Upon completion of this course, students should know:
- Basic geology and climatology of the American Southwest
- Techniques of dating and reconstruction of past environments
- Basic background information of environments of the American Southwest
- Past human interaction with environments in the American Southwest
- Current human interaction with environments in the American Southwest
- Students will research a major topic in human-environmental history of the American Southwest, culminating in an outline/essay or a storyboard/video (WRIT):
- WRIT: Students will demonstrate rhetorical awareness and writing proficiency by writing for a variety of contexts and executing disciplinary genre conventions of organization, design, style, mechanics and citation format while reflecting on their writing development
- Students will think critically every lecture (QNT):
- QNT: Students will demonstrate competency in working with numerical information by critically analyzing quantitative information, generating ideas that are supported by quantitative evidence, assessing the relevance of data and its associated implications in a variety of contexts, and communicating those ideas and/or associated interpretations using various formats (graphs, data tables, equations, oral presentations, or written reflections)
- Students who pass will fulfill gen-ed requirements for Exploring Perspectives in Natural Sciences (EPNAT):
- EPNAT: Students will identify the approaches and methodologies of Natural Scientists, using evidence to critically analyze questions and arguments, and consider contributions of this perspective to finding solutions to global and/or local challenges
Please be sure that you have fulfilled the stated course prerequisites: two courses from Tier One, Natural Sciences (NATS 101, 102, 104).
UA General Education
- Geos. 220 is a General Education course. The UA on-line catalog states that General Education "helps University of Arizona graduates attain fundamental skills and a broad base of knowledge to respond effectively to a complex world." Geos. 220 is designed to fulfill this mandate.
According to UA policy, students are expected to be regular and punctual in class attendance and to fully participate in courses. Students themselves are primarily responsible for attendance and class participation, so in this course attendance will not be monitored directly. In general, students who have attended lectures regularly and attentively have done well in this course, and vice versa. Click here for a Daily Wildcat op-ed piece about attending class, and click here for a Daily Wildcat cartoon about attending class.
The UA policy regarding absences for any sincerely held religious belief, observance or practice will be accommodated where reasonable. Assignments and/or exams may be fulfilled late after such absences.
The UA policy on absences preapproved by the UA Dean of Students (or dean's designee) will be honored. Assignments and/or exams may be fulfilled late after approved absences.
Content lectures have a graded exercise for critical thinking, which has the effect of taking attendance. After each lecture, go to D2L to do that day's exercise. The exact topic will be given in lecture. Critical thinking answers should be about 150 words, i.e., approximately a letter to the editor to the newspaper. Critical thinking will be evaluated on the basis of (1) providing an opinion backed up by data about the topic of the day and/or (2) considering multiple sides of the topic of the day. This exercise will be open on D2L from 3:30 to 11:59 PM on each lecture day that has a content lecture.
If you become ill with the flu, do not come to class until you have had no fever for 24 hours. You are responsible for contacting the instructor via email or phone as soon as you can to inform that you are ill. You are also responsible for any work missed while you are ill including assignments and exams.
- There is no textbook for the course, simply because no single book covers all of the varied content of this course while not including other, non-relevant topics.
- Instead of a single textbook, specific short readings will be available through this course web page. The reading assignments will be updated as needed.
- For some readings you will need the Adobe Reader application loaded onto your computer; that is pretty common these days and most university computers already have Adobe Reader installed. If you need it for your own computer, it's a free download from here: Adobe.
- For some readings you will need to know a password, which will be divulged in class. If you forget the password, contact the instructors.
- If you have problems with computer access to any readings or assignments, contact the instructors.
Course Web Page
- The url for the course web page is https://geos220.ltrr.arizona.edu/syllabus.
- This page contains the course syllabus plus links to notes for each lecture, homework assignments, quiz and exam dates, professor and TA contact information, and other important sites of interest.
- Students who access the web syllabus regularly during the semester do well in this course.
- Details of the writing assignments, quizzes, and/or outside activities are posted only on the web page and will not be distributed in class.
- For seeing your own scores, check in with D2L. BTW, here's a Daily Wildcat comic about D2L.
- UA gen-ed courses are expected to be writing intensive. There are short writing activities and one 1000-word essay in this course. The essay is intended to provide a chance for in-depth research on a complex topic, to foster critical thinking, and to allow practice for writing.
- The option exists to do a video documentary in lieu of an essay. Video production is fun and not difficult, and I teach it in all my courses. Video production requires voice over narration, so the video option has plenty of writing.
- This writing assignment will be broken into two parts:
- A topic-sentence outline OR a storyboard, the pre-video component of video production. Either way, cited references are expected, the more references the better, with a good mix of kinds of references (50% of grade)
- The written essay OR a video documentary, again with cited references (50% of grade)
- The grading of the outline/storyboard and essay/video will be based primarily on the effective use of research material and the overall quality of the writing. In general, the more reference material cited the better, and having just one topic in each paragraph, including an identifiable topic sentence, would be good. To improve writing quality, check out the free UA Writing Skills Improvement Program, which includes presentations on essay organization and paragraph structure, two areas of consistent difficulty in this course.
- As but an example of a video documentary that can satisfy our writing requirement, click here to see a short promo video for a Spring class I teach that also incorporates video documentaries.
- Grading will be based on:
- critical thinking for each content lecture (D2L)
- 4 in-class quizzes (quick)
- 2 outside activities (easy and fun)
- 1 writing assignment (difficult)
- 3 exams (two midterms and a unit final exam with a comprehensive section)
- The distribution of credit and grading will be as follows:
Points Lecture critical thinking 50 (2 points per content lecture) Quizzes 80 (20 pts. each x 4 quizzes) Outside activities 50 (25 pts. each x 2 activities) Writing Assignment 200 (100 pts. each for outline/storyboard and essay/video) Midterm Exams 400 (200 pts. each x 2 exams) Final Exam
220 (200-pt. unit exam + 20-pt. comp.)
Total Points 1000
- Letter grades for the course will be determined from the percentage of earned points relative to the total, as follows:
900-1000 points (90 to 100%) = A 800-899 points (80 to 89%) = B 700-799 points (70 to 79%) = C 600-699 points (60 to 69%) = D below 600 points (60%) = E INCOMPLETES WILL BE CONSIDERED
ONLY FOR DIRE MEDICAL EVENTS
Exams and Other Graded Assignments
- Students can arrange with the instructors to take exams or quizzes in advance of scheduled dates if a valid reason for missing the scheduled dates is offered, such as: personal or family emergency, medical reasons, or UA Athletic obligations. If an exam or quiz is missed for unforeseen reasons (e.g., car accidents, sickness, emergencies, etc.), a make-up may be arranged within three days of the scheduled exam so long as proof of the necessity of the absence is provided (e.g., a written statement from a medical doctor, etc.).
- According to UA policy, the Final Exam MUST be taken during the scheduled time, unless you're unfortunate enough to have two at the same time or four on the same day, in which case please see the instructors.
- Completely missing exams or failing to do other graded essays and activities makes it difficult to succeed in any course. For example, if nothing is turned in for an assignment, a score of 0 will be entered for that grade.
- Students who are late on a graded assignment and don't have an acceptable excuse may turn in that assignment late for up to one week past the due date.
- However, the maximum score for late work will drop 10% after the due date.
- In short, it's best to turn in assignments on time, but if an assignment is late, it's still worth turning it in. After one week late, the door closes on assignments.
Extra credit is offered, as follows:
- "Extra" credit does not mean "instead of" credit. That is, an extra credit score can be added to the final point total only by students who have turned in everything else. Click here for a cartoon on this concept.
- Only one extra credit assignment per student may be turned in.
- The extra credit project is to be a self-directed field trip to an approved prehistoric cultural site in the Southwest. The exact details of extra credit assignments can vary between students, and many possibilities exist near Tucson and throughout the Southwest:
- Near Tucson: Murray Springs mammoth kill site, Casa Grande, Tumacácori, Besh Ba Gowah, Tonto, Pueblo Grande, Mesa Grande.
- Farther away: Homolovi, Montezuma Castle and Well, Flagstaff Sinagua sites (Wupatki, Sunset Crater, and Walnut Canyon), Petrified Forest (with emphasis on Puerco Pueblo), Canyon de Chelly, Navajo Tsegi Canyon, Gila Cliff Dwellings, Pecos, Salinas Pueblos, and Coronado Kuaua.
- Extra credit trips need not last more than a day, and many could be a mere stop-in while traveling for other reasons. Spend at least a couple hours at the site learning about its prehistoric human-environment interactions.
- Four things will be required to earn extra credit points from a field trip:
- You must consult with Dr. Sheppardin-person or by Zoom, not just by emailbefore your trip to be sure that your proposed trip is acceptable and to help prepare yourself to maximize your visit. For example, you will get recommended reference material to take with you. If you're already traveling and see some place appropriate to spend time at, do it and come see me after.
- Make a short (2 to 3 minutes is all) video showing lots of pictures of what you saw and explicitly linking your site to lecture topics of the course, the more the better. See this one by Paul as but an example of a trip video: Paul's Crack-in-Rock trip video. Discuss dates, how dating was done, where and how food and water were obtained, and when and why the people left. In the video credits, include at least TWO citations, one of material obtained at the site AND one of a published or web-based reference related to your site. Include narration and music in your video.
Note: If you hate the thought of making a video, and won't do an extra credit trip because of the video thing, then a written report is allowable.
- Include in your video (report) an aerial photo of the site, with at least one comment of discussion about what is visible about the site from above.
- Include in your video (report) at least one picture of you at the site. Make it obvious that you were at the site.
- The total possible points available for extra credit is 50.
- Extra credit videos (reports) may be turned in at any time up until November 14, 2023, via D2L.
Code of Conduct
It is expected that we allprofessors, TAs, and students alikeobserve rules of common courtesy, such as:
- Adhere to the ABOR code of conduct and the UA Code of Academic Integrity.
- Adhere to the UA Threatening Behavior by Students Policy prohibiting threats of physical harm to any member of the University community, including to oneself.
- Adhere to the UA Policy creating and maintaining an environment free of discrimination and harassment.
- If you must arrive late or leave early (something not encouraged), please do so quietly.
- If you have a phone (who doesn't, besides the instructor?), please turn it off during class. If you must talk on your phone (does anyone talk on the phone anymore?) or text message someone during lecture, please do that outside of class.
- If you must read the newspaper (anyone?), tackle the Wildcat crossword and sudoku puzzles (anyone?), study for other courses (occasionally), sleep (lots), surf the web, update Facebook, Farmville, shop Ebay, play online poker, watch DVD movies, binge watch Thrones, or do anything else not related to this course during our lecture time, please do it elsewhere, not in class. These activities are obvious (click here for an example) and are officially considered disruptive. See here for a UA student opinion about surfing the web in class.
- Click here to see research saying people who multitask really aren't good at multitasking.
- There will be no racism, sexism, or violence tolerated in the classroom.
- Students are encouraged to share intellectual views and discuss freely the principles and applications of course materials. However, graded work/exercises must be the product of independent effort unless otherwise instructed. Students are expected to adhere to the UA Code of Academic Integrity as described in the UA General Catalog. See here.
- It's acceptableeven encouragedto study together, of course. However, cheating will not be tolerated, including but not limited to:
- Copying work of others during exams or quizzes.
- Turning in work of others as your own, including work of students from past semesters.
- Plagiarism on papers. Click here for a definition of plagiarism.
- Special note on plagiarism: Some definitions of plagiarism imply that all that is necessary to avoid it is to put someone else's text in quotes and then cite the original source. While technically this may be true and acceptable in some academic settings, copying someone else's text (put in quotes or otherwise) is hereby NOT acceptable in this course. This includes text from fellow students or students from past semesters, published articles or newspapers, and web sites. In short: Citing yes, quoting no.
- Another note on plagiarism: If you'd like a fictional account of plagiarism, try Stephen King's, "Secret Window, Secret Garden," definitely a horror story. The movie, "Secret Window" with Johnny Depp and John Turturro, wasn't bad either.
- Students found cheating on any assigned work will receive a score of 0 for that assignment.
UA Nondiscrimination and Anti-Harassment Policy
- The University of Arizona is committed to creating and maintaining an environment free of discrimination; see here. Everyone is encouraged to express well-formed opinions and their reasons for those opinions. The classroom is tolerant and open where opinions can be expressed without resorting to bullying or discrimination of others.
Accessibility and Accommodations
- At the University of Arizona, we strive to make learning experiences as accessible as possible. If you anticipate or experience barriers based on disability or pregnancy, please contact the Disability Resource Center (520-621-3268, https://drc.arizona.edu) to establish reasonable accommodations.
- If the schedule outlined below conflicts with major religious observances, please let the professor know.
- If English is not your native language and you feel that you must use a translation dictionary during exams, please contact the professor.
- Students requiring accommodation in testing or note taking: Please notify the professor and provide the Disability Resource Center letter within the first few days of the course.
- Student athletes and others who need signatures periodically: Please notify the professor that you'll be needing signatures generally, and please alert the professor before a particular signing period is due so that your most up-to-date grade can be calculated.
- Honors College students: An Honors Contract is allowable. See the instructor to arrange those details.
