Course Goals

The objective of this course is to ground current and compelling environmental issues firmly in their fundamental underlying scientific principles.  To do so we will study selected linked components of a complex and dynamic earth system.  Rather than attempt a survey of the entire global change research effort, we will investigate a few topics -- climate change, biodiversity, fresh water resources, and population dynamics -- in some detail.  Class time will be divided between lecture, hands-on activities and discussion, to ensure the essential scientific concepts behind these topics are well understood.  Along the way we will meet the Tier I Natural Sciences General Education requirements.  Note: You don't have to be in the Honors College to take this section, but you do have to commit to Honors-level expectations.

By the conclusion of this course, students will be able to perform the following tasks, via demonstration of proficiency in related assignments:

Overarching Goals
Skills Goals Assignments
Form and defend opinions on current controversies in global change science. Make a clear and concise argument, based on carefully-referenced facts and logic, within a 2 page essay. Homeworks, Readings, In-class Discussions.
Apply a small set of  scientific concepts to solve problems in unfamiliar contexts. Approximate solutions to quantitative problems using "order-of-magnitude" estimation techniques. Demonstration Assessments, Take-Home Quizzes, In-class Exams, Final Exam
Make inferences based on scientific observations.
Interpret data presented in graphs and figures.
Demonstrations, Take-Home Quizzes, Final Exams

Class Logistics

Time and Place: TU/TH, 11:00-12:15pm, Integrated Learning Center 145.
Instructor: Michael Evans, Laboratory of Tree-Ring Research, 214 W. Stadium (up stairs to 2nd floor at Gate 15; look for my name on the blue door).  ph 626-2897; email: mevans@ltrr.arizona.edu.  More about the instructor is here.
Office hours: Tu/Th, 3-4pm, in OSCR Underground, Office 1, in the ILC. (Information Commons), or by appointment.  I hope this location is more convenient for you than the Stadium.  I may be unavailable for some scheduled office hours but will try to pre-announce these.  I will also try to answer emailed questions and requests within 24 hours.
Adding this class: That's fine (assuming there's space).  But do tell me that you're joining; find out about missed assignments ahead of time so we can integrate you into the class; get caught up quickly.


Reading and Course Materials:

There is no required textbook for the course.  Readings from selected topical, authoritative and timely sources are linked in the Schedule/Syllabus below as password-protected Portable Document Format (pdf) files.  Lecture notes (may/may not include work and exercises performed in class) will be linked as html files and also as downloadable Microsoft PowerPoint-compatible files.  They will often but not guaranteeably be available prior to class meetings, and are subject to change.  We will make use of copyrighted materials under academic Fair Use Policy of applicable copyright law (see UA and U Texas notes on this, and what it means for you and me.)

Assignments:

This course is not about memorization.  Rather, it is about the goals described above.  I will ask you to think about the material we discuss in class and to use it to solve problems.  In-class exams will each cover their respective course topics, and will test whether you can apply concepts learned from lectures, homeworks, quizzes, demonstrations and readings.  Homeworks are short essay assignments in which you'll think about course topics in a real-world, problem-solving context. Take-home quizzes will be based on lecture concepts and reading, and will give you practice in the problem solving skills needed for in-class exams and the final exam.  Demonstration assignments will ask you to summarize and apply concepts illustrated by the in-class demonstrations.  In-Class Exams will primarily test your ability to use basic scientific concepts to solve problems in unfamiliar contexts.  The Final Exam will be similar to the hourly exams, but will be cumulative over the semester.

Feedback: 

I would like to schedule a mid-semester focus group evaluation (why wait until the end of the semester, when we can fix things now?) for the week of Oct 16th.  I may also request occasional 1-minute anonymous evaluations at the end of class, in which you'll quickly note the main point you brought away from class, as well as the main question left unresolved for you.  I'll also welcome constructive feedback during office hours, by email, or after class.  This will help me resolve outstanding questions and adjust the pace of the course accordingly.  We will also have end-of-course evaluations.

This is your education, so class attendance is not mandatory.  It's up to you to make the most of your time and education dollar.  However, be aware that: (0) We will discuss material that may or may not be in the readings or lecture notes; (1) we will have in-class exercises for credit which in most cases cannot be made up; (2) If you don't show up at all, I may administratively drop you from the course; (3) class will be fun.   Do you have occasional but known upcoming schedule conflicts?   Don't wait until afterward; please talk to me well beforehand so we can make sure you keep up with the class.

Course requirements:

Please note: You cannot pass the course without completing all homework assignments, taking all three in-class exams, and taking the final exam.  Demonstration assignments, when possible, may be substituted with Internet-based simulations I will provide.  No late assignments will be accepted without prior arrangements.

Academic Rules and Academic Integrity:

See the University Academic Integrity Policy. You are responsible for knowing these rules, which ultimately ensure the quality of your education.  Please take note: Plagiarism and cheating are serious academic offenses.  I must report and respond to all such offenses per official university guidelines.

How to study:  

I want you to understand the ideas we'll discuss, enjoy the course, and get good grades.  Study habits which will help you master this course with ease are:

Come to office hours for more information, and talk to your classmates, who are a great resource.

Academic resources: The University and the Internet offer many sources of help (Or talk with me and I'll help you find what you need): 

Disability resources: 

Do you have a physical or learning disability?   Please speak with me right away about accommodations.  You will only need to show me a faculty letter from the Disability Resource Center, and we can make arrangements from there.

Instructor's schedule: With full responsibilty for this course, and partial responsibility for a 150 seat section right afterward, we will all have to be especially organized.  On the bright side, I've cancelled or postponed most of my usual traveling.  If you can't make regular office hours, I may hold office hours by appointment; please email in advance.  I may go to San Francisco for a meeting for a few days during finals week; I'll keep you posted as my schedule develops.
