Welcome to PHYS 231A, my name is Suzanne White Brahmia <firstname.lastname@example.org> (pronouns she/her), and I will be your instructor.
This class has laboratory and lecture components.
In the lecture component we will learn about the concepts of measurement, and the other quantities associated with thinking about and reporting measured quantities. The homework each week will help you master concepts discussed in lecture.
In the laboratory component you get to design four experiments and put what you have learned in lecture into practice by writing experimental reports capable of convincing a colleague about the validity of your conclusions, which is a key part of the scientific method.
In this class everyone is welcome, regardless of other identities you hold in addition to that of physics student. The norm in this class is to strive for treating each other respectfully. Please read and abide by the Code of Conduct.
Mode of operation:
- This class is planned to be conducted in-person unless the University announces otherwise. You are expected to participate in class to fully benefit from course activities and meet the course’s learning objectives. You should register for this class only if you are able to participate in-person.
- To protect your fellow students, faculty, and staff, if you feel ill or exhibit possible COVID symptoms, you should not come to class. For more COVID related information, please visit https://www.washington.edu/coronavirus/.
- When absent, it is your responsibility to inform me and your group members in advance (or as close to the class period as possible in the case of an unexpected absence), and to request appropriate make-up work as per policies established in the syllabus.
Upon successful completion of this course, students will be able to:
- Design both a hypothesis testing and a hypothesis generating experiment.
- Conceptually understand the statistical underpinnings of uncertainty.
- Quantify uncertainty in measurement and modelling.
- Write a scientific report with valid conclusions and discussion of results.
- Prepare and deliver a scientific presentation.
- Function effectively on a professional team to produce deliverables.

- Reading assignments are from Measurements and their uncertainties a practical guide to modern error analysis by Ifan Hughes. The UW has a license for the ebook.
- Lectures are from 11:30 AM to 12:50 PM on Tuesdays in PAA A118. Lecture homework (covering the prior week's topics) is due every Monday at midnight Pacific. The lectures will be recorded and posted for students who cannot make it to lecture.
- Passively watching a long lecture is exhausting. In this course, lectures will involve collaborative activities designed for efficient learning. In order to benefit from the in-class activities, and to not let your group down, it is essential that students do the assigned reading before lecture.
- An important learning objective of this course is that you have both a computational and conceptual facility with core statistical methods and ideas for interpreting data. To reinforce the analysis methods discussed in lecture and the reading, there will be an assignment due each Monday. These can be found under "Assignments" on the left menu. In order to pass this course, you will be expected to achieve a score of 95% or above on the homework, and you will be allowed to resubmit your work (with generous hints along the way) until you achieve this score.
The laboratory activities will be completed in person in B042.
We will use Slack in this course for collaborative work with your Lab Group, and we will help you become proficient in its use to catalyze effective teamwork . The first assignment for this course is:
- Complete a Lab Logistics survey that will help us match you with peers to form Lab Groups.
- Complete survey of Scientific Attitudes Towards Experimentation
- Get Slack running on your device using the description and instructions here.
Your TA will place you in a group and invite you to your section's Slack channel.
Lab meeting times
- There are three lab sections per week:
- Section AA, Tuesday 1:30PM-4:20PM (TA: Alex Reynolds)
- Section AE, Tuesday 4:30PM-7:20PM (TA: Chris Matsumura)
- Section AF, Wednesday 4:30PM-7:20PM (TA: Chris Matsumura)
Labs and lab reports
- The first lab will provide an opportunity for everyone to establish norms within your lab groups. You will work with these groups throughout the quarter.
- Over the remainder of the quarter your group will complete four additional experiments. Working in subgroups of two or three students, you will submit a single lab report for the subgroup.
- With my permission you will be excused if you cannot attend a single lab due to sickness or other valid excuse. However, if you must miss both weeks of an experiment, you will need to join a group from another section with my approval.
- After the deadline for submitting the reports has passed, you will be assigned a random report from another group. You will leave constructive feedback and grade it using the same rubric the TA will use. The grades you give will not be used towards the grade for the report, but the group will be able to see how you graded it and they will be able to see your comments, although they will not see who graded it and left the comments. You will be given credit for leaving constructive feedback.
- Your group will give an oral presentation on one of the experiments at the end of the quarter. More information will be provided soon.
Data Collection and Analysis
- Your group should also set up a virtual space like a Google Doc or OneNote to share data, pictures etc. for all group members to access as you prepare your reports. It is important that you do enough analysis during the lab time to determine if you have the necessary data to complete your lab report before the lab session ends - often you'll want to adjust something and retake data once you've done a quick analysis.
- We will have a final exam during class time on Tuesday November 30.
- Note that there are no make-up exams.
- Students with outside professional, service, or career commitments (i.e. military service, ROTC, professional conference presentation, NCAA sports, etc.) conflicting with the exam date must contact me early in the quarter to establish alternate examination procedures.
- Students who are sick, or are in quarantine, must contact me before the exam.
- Exam scores for students who miss the exam without making prior arrangements will be zero.
- The course grade will be based on the following:
- Lab participation, 10%
- Lab reports, 40%
- Lab presentation, 15%
- Lecture Homework, 10%
- Final Exam, 25%
- Each student is required to participate in report preparation, and submit four completed lab reports during the course of the quarter to pass the class.
- You will lose 10% for every day that a lab report is late.

Research Study Information
This course is part of a research project, led by Doctoral Candidate Jared Canright. The project examines student reasoning, and attitudes about physics, with the goal of improving physics teaching. By enrolling in this course, you are automatically included in the study. Early in the quarter, students will have an opportunity to learn about the study and to remove themselves from the study if they wish. Your instructor will not know whether or not you participate. Please click on this link to review the details of the study, contact a member of the research team, or remove yourself from the study.
- We are committed to ensuring a safe environment on campus. Please check out the resources available here, http://www.washington.edu/safecampus/.
Washington state law requires that UW develop a policy for accommodation of student absences or significant hardship due to reasons of faith or conscience, or for organized religious activities. The UW’s policy, including more information about how to request an accommodation, is available at Religious Accommodations Policy (https://registrar.washington.edu/staffandfaculty/religious-accommodations-policy/). Accommodations must be requested within the first two weeks of this course using the Religious Accommodations Request form (https://registrar.washington.edu/students/religious-accommodations-request/).
Mask and COVID Safety Policies
Although the lecture and lab have HEPA air filters and a good ventilation system, it is important for everyone to follow the safety guidance since you will be seated close to your classmates.
- Everyone must be vaccinated against COVID or have an approved exemption no later than Oct 18.
- Masks are required both in lecture and in the lab.
- No one is allowed to eat in lecture or in lab.
- You are allowed to drink only if you can sanitize your hands both before and after touching your mask to remove it briefly.
