Math 110A - Section 03 - Spring 2024
Subject to change.
Welcome to Abstract Algebra! I’m looking forward to meeting you all and starting our work together. Please let me know if you have any questions at all, about our course or anything else.
Important note about a possible work stoppage during the semester.
The California Faculty Association (the labor union of Lecturers, Professors, Coaches, Counselors, and Librarians across the 23 CSU campuses) is in a difficult contract dispute with California State University management. It is possible that we will call a strike or other work stoppage this term. I will promptly inform you of any schedule disruption. Our working conditions are your learning conditions; we seek to protect both. For further information go to CFAbargaining.org.
First half of a one-year introductory course in algebraic concepts. Topics include: groups, subgroups, properties of groups, permutation groups, factor groups, homomorphism theorems. This is a 3 unit class.
Students should have successfully completed an Introduction to Formal Mathematics (Math 108) with a grade of C- or better before taking this course. If you have any questions or concerns about this prerequisite, please check in with me as soon as possible.
In this course, students will (1) increase their capacity for critical thinking and fact-based reasoning, (2) develop the necessary competency with group theory for further work in mathematics and other fields, (3) improve their written and oral communication of mathematics, and (4) develop the skills and mindset for solving problems in a team. Specific content outcomes are for students to be able to
Members of this class represent a rich variety of backgrounds and perspectives. Our class commits to providing an atmosphere for learning that respects diversity and recognizes it as a source of strength. While working together to build this intellectual community, we ask all members to:
We will further develop this agreement together in class.
Overall grades for the course will be determined from the course components listed above with the following weighting:
Homework will usually be assigned each class meeting, and due at start of the next meeting. The goal of this daily work is for us all to critically engage with the material, uncover points of confusion, and deepen understanding. Confusion and struggle is an important part of the learning process that we’ll need to learn to embrace.
These assignments allow me to see your work outside of the classroom, before we come together to collaboratively revise. You are allowed and encouraged to work together, but you are expected to write up your solutions on your own. Please take care that your work is well-organized and fully-justified with proper grammar, punctuation, and spelling.
These assignments will be graded on the following ten-point system. (The score will be the highest one that applies.)
| 10 | At most one problem was skipped. All completed problems were seriously attempted with well-organized and fully-justified work |
| 8 | At most two problems were skipped. All completed problems were seriously attempted with well-organized and fully-justified work |
| 6 | At most half of the problems were skipped. All completed problems were seriously attempted with well-organized and fully-justified work |
| 4 | At least half of the problems were completed collaboratively in class when it is due. All completed problems were seriously attempted with well-organized and fully-justified work |
| 0 | None of the above |
Outside Resources
Please do not use resources from outside our class to complete the homework. It is acceptable to watch a video or go to our Math Lab for general conceptual questions, but please do not use such resources for direct assistance with the problems.
Learning to discuss mathematics is a highly valued part of this course. This component will evaluate your progress in areas such as ability to describe a solution (with clarity and thoughtfulness), ability to share and shed light on your difficulties, and ability to listen critically and respond accordingly. The best way to excel in this component is to be engaged in class each day, active in discussions, and prepared to present.
Presentations will be graded on the following scale. (The score will be the highest one that applies.)
| E | Exceeds Expectations. Thorough and detailed solution; exceptionally clear and thoughtful presentation. |
| M | Meets Expectations. Well-thought out approach capturing the key ideas; clear presentation. |
| I | In progress. Serious attempt, but has a significant flaw/gap or lack of clarity. |
| U | Unsatisfactory. Minimal or no progress was made. |
Participation will be graded on the following scale. (The score will be the highest one that applies.)
| E | Exceeds Expectations. Asking questions, contributing to meaningful discussion, or offering supportive comments essentially every meeting. |
| M | Meets Expectations. Asking questions, contributing to meaningful discussion, or offering supportive comments at least once per week. |
| U | Unsatisfactory. Never or very rarely participates in class or is disrespectful. |
The presentation and participation rubrics will be combined as follows. (The score will be the highest one that applies.)
| 90–100% | Receives M/E for participation; has at least 3 M/E presentations prior to each midterm. |
| 80-89% | Receives M/E for participation; has at least 2 M/E presentations prior to each midterm. |
| 70-79% | Receives M/E for participation; has at least 1 I/M/E presentation prior to each midterm. |
| 60-69% | Receives U for participation; has at least 1 I/M/E presentations over the semester. |
| 0–60% | Receives U for participation; never presents or all receive a U. |
There will be weekly assignments where you are asked to carefully revise and type up with $\LaTeX$ a small subset of the problems we covered. Becoming proficient with $\LaTeX$ is one of the aims of the course—I will support you as much as needed with this. Completed assignments are to be submitted via Canvas by the posted due date. Please take great care not to plagiarize or allow your own work to be plagiarized.
When writing up your solutions, you may work with one partner on this and turn in the same document for both of you. If you do this, please make sure that you have truly collaborated on both the mathematics and the writing.
There are 2 midterm exams. They are tentatively scheduled for Mar. 07 and Apr. 25. There is also a Final Exam scheduled for Thursday, May 16 from 12:45 AM – 2:45 PM
