Teaching Portfolio Brian Johnson University of Nebraska-Lincoln Syllabi MATH 203–CONTEMPORARY MATH SECTION 008, 1:30-2:20 MWF, OLDH 308 SPRING 2007 Welcome to Math 203, my name is Brian Johnson, and I will be your instructor for this course. My office is 314 Avery Hall, and my (official) office hours this semester will be from 9:30am-10:20am Mondays and Wednesdays and 1:30pm2:20pm Tuesdays and Thursdays. If these are inconvenient, then please email me ([email protected]) or call me (Office 472-8244) and we will work something out. Another good place to find this information is on my homepage found at http://www.math.unl.edu/∼s-bjohns67/ TEXT: We will be using A Mathematical View of Our World by H. Parks, G. Musser, L. Trimpe, V. Maurer, and R. Maurer. ISBN: 0-495-01061-8. COURSE OBJECTIVES: In this course we will explore the practical applications of mathematics in the real world. Where many math courses place emphasis on mastering procedures and methods, this course focuses on developing problem solving skills and logical thinking. Further, we will explore some of the more useful and beautiful areas of mathematics and hopefully obtain a higher appreciation for them. In addition, this course is intended to develop writing and communication skills in mathematics. EVALUATION PROCEDURES: You will be assigned a final grade for this course based on the following: Homework: 100 points Quizzes(3): 75 points Exams (2): 200 points Journals (5): 200 points Project: 125 points Total: 700 points. Your final grade will be calculated using your accumulated point total. If you get the following scores, you will receive no less than the grades listed: 679–700: A+ 609–629: B+ 651–678: A 581–608: B 630–650: A– 560–580: B– 539–559: C+ 469–489: D+ 0–419: F 511–538: C 441–468: D 490–510: C– 420–440: D– Note: If you are taking this course Pass/No Pass, you must earn a final grade of at least C (511 points) to receive a pass grade. HOMEWORK: At the beginning of each week, I will assign homework problems to be turned in at the beginning of the following week. Each homework assignment will be a subset of (in fact, most likely all of) the problems listed in the syllabus of assigned problems on the last page. I will usually choose to grade 3-4 of all of the problems turned it, but will not let you know in advance which problems will be chosen for grading. Most homework assignments turned in will be worth 10 points each, but this will vary as each week varies in the amount of material we cover. While some of the problems on the last page will not be collected, I advise you to work as many of the problems as you can. If possible, do more than assigned on the last page. Mathematics is not a spectator sport. Just as you cannot train for a marathon by watching others run, you cannot improve your mathematical abilities by watching someone else do problems (this will benefit you greatly when the exams roll around). 1 QUIZZES: There will be three quizzes at the end of the semester over the last three chapters. Two of them will be in class, and one will be a take-home quiz. Each will be worth 25 points. Only valid (i.e., university excuses, signed doctor’s notes, etc.) makeup quizzes will be given. EXAMS: We will have two in-class hour exams, worth 100 points each. Only valid (i.e., university excuses, signed doctor’s notes, etc.) makeup exams will be given. JOURNALS: This course is designed to meet Integrated Studies requirements. Thus, there will be five journaling assignments throughout the semester, approximately every two weeks or so. Your grade for each journal entry will not only be based on content, but spelling and grammar as well. PROJECT: This course involves a project worth 125 points. Details on the project will be given at the appropriate time during the session. Expect a 4–6 page report that will involve some sort of research and/or calculations. ACADEMIC HONESTY: All work in this course must be completed in accordance with the Student Code of Conduct found in the University of Nebraska– Lincoln Undergraduate Bulletin located at: http://www.unl.edu/unlpub/undergrad/. DISCRIMINATION POLICY: The Department of Mathematics does not tolerate discrimination or harassment based on ethnicity, gender, creed, or sexual orientation. If you believe you were discriminated against or harassed, contact either myself or the department. If you believe your grade was assigned based on any of the above items, then contact (in order) myself, the department chair, the department grading appeals committee, the college grading appeals committee, and the university grading appeals committee. IMPORTANT DATES: • 25 Jan 2007 Last day to drop without a “W.” • 7 Mar 2007 Last day to change to or from Pass/No Pass. • 11 Apr 2007 Last day to withdraw. MISCELLANY: • If you need to miss class, be late for class, or leave class early for any reason, let me know ahead of time–preferably by email. • Any students with disabilities or other special needs, who need special accommodations in the course, are invited to share those concerns or requests with the instructor as soon as possible. • Please make sure to check the email address associated with your Blackboard account and make sure it is one you check regularly. I will at times be using Blackboard to make class announcements, and I want to be sure everyone receives them.

The journals should be 1-2 pages typed and double spaced in 12 point font or smaller. Recall the first journal assignment: • Assignment: Introduce yourself. That is, tell me a little bit about yourself. This is a very broad assignment, but some answers I would like you to include are: What is your mathematical background? What are some of the things you have liked/disliked about previous math courses you have taken? Why are you taking this class? What do you hope to get out of this class, or what would you like to learn? Aside from those few questions, you may take this in any direction you would like. In reference to the first assignment, I’d like you to comment on some of the following: How did this class, if at all, affect your mathematical thinking? What did you like/dislike about this class? What did you get out of this class, and did you learn what you wanted? Are there any future math classes you will be taking, and if so, what are they? If there were specific assignments or chapters that you liked or didn’t like, what were they and why?

He will tell you why a problem is worked a certain way rather than just hammering through examples, this helps us understand much better. Brian is also very helpful our of class and is almost always available. I have two things to say: One is that the Gateway Exam needs some work, too many problems. As for the (unreadable), my teacher Mr. Johnson is good at his job. • very good teacher! • Hire Brian Johnson as a teacher. Very good at what he does.

Just a suggestion, making homework mandatory (needs to be turned in) would be more encouraging to do it. � He is a great teacher. His lectures weren’t boring and math was pleasant thanks to him. I have gone to his office numerous times for help and always has time. Even if he’s eating lunch he helps me. He graded very fairly and always help me if I needed it. He was the best math teacher I ever had. NO LIE. I’d take another class with him if I could. And I love his math jokes. • • Great teacher. My favorite yet! Brian was a great teacher. If I was ever lost, he was always willing to help. He took a lame subject (sorry!) and made it almost fun to come to. • Great job! • Instructor, methods, content, pace, etc. was perfect! • Brian Johnson is Awesome! • F*** yeah, Brian! • • No concerns � My only suggestion is for him to tell students to be quiet while he is teaching. 2 Math 208 - Multivariable Calculus Spring 2011 Qualitative results have been averaged.

I loved this class and Brian Johnson. He is the best teacher I’ve had in my time at UNL! I hope I can take higher level courses from him. • great teacher, much better than my last one • Good class! Enjoyed it a lot! • I think this class would benefit greatly from a little focus on why we are learning what we are learning. Application is always nice.
