Course Communications

General questions about the course? Use Ed Discussion.

With so many students in this class, it’s simply not feasible for the instructor or the TAs to respond to individual emails about the course content or schedule. If you have a question along these lines, please post it to Ed Discussion rather than emailing one of us directly. That way you will be accessing the collective knowledge of literally hundreds of people, who are all thinking about the same things as you. You are likely to receive an answer much more quickly than if you only email an instructor or TA. The TAs and instructor will be actively monitoring the discussion board and will answer questions as we find them. Many of your colleagues will probably have the same question as you, so posting your question on the discussion board helps everyone in the class.

How to help me respond to your emails:

I receive a lot of emails. I will do our best to respond within 24 business hours to an email you send me, but to maximize your chances of hearing back, please adhere to the following guidelines:

  1. Email me about private matters, such as grades, or requests for private appointments. Questions about course content or the course schedule should be posted to Ed Discussion. If you send me an email with a non-sensitive or non-personal question, I will not respond.
  2. Use your official UW email to send your message. This helps me know that I am really talking to you and not some rando with a hotmail account who wants to know about you, because you have to log in to your UW email using your UW NetID credentials. (Learn how to set up UW Gmail or Office 365.)
  3. Indicate your TA section and your Full Name
  4. Present yourself in a professional manner
    • Use an appropriate salutation (“Dear Prof. Craig,” or “Hi Prof. Craig,” etc.) and sign-off (“Best, Leslie Jones” or “Thanks, Jerrod Carmichael” etc.).
    • Write in complete sentences.
    • Employ proper punctuation and grammar

How to make an appointment to speak with me privately:

If you would like to schedule a time to speak with me privately, I am happy to meet with you! I schedule student meetings in 15-minute blocks. Meetings can be held either in person or on Zoom. When you contact me to set up a meeting, please follow these steps:

  1. Send an email. I will not remember to put the meeting on the calendar if we only speak in person.
  2. Indicate whether you want to schedule a private meeting (if you have questions about grades, DRS accommodations, etc.), or if other students may attend (if you want to discuss course content).
  3. Indicate whether your prefer an in-person or Zoom meeting. If Zoom, I will send you a meeting link once we confirm a day and time. Note: Depending on the day/time, I may only be available via Zoom. 
  4. Suggest two or three possible days for our meeting, and provide your detailed schedule on those days. I will email you back with a 15-minute block.
  5. Confirm via email that the day and time I suggest will work for you. 
  6. If you have to reschedule or cancel a meeting we’ve set, let me know as soon as possible.

DON'T COME TO CLASS SICK

If you're sick (with anything!) or have received a positive COVID test, do not come to class, even if it is on an exam day. The Chemistry Department has a generous sick leave policy. You can request an excused absence at the Chemistry Department Absence Reporting Form. If you're feeling sick, please stay home and take your first opportunity to get tested.

"What if I miss an exam due to illness?"

Consult Policies for Quizzes/Exams for information about how we will handle exams scores that are missing due to illness.

ACCESS AND ACCOMMODATIONS

Your experience in this class is important to us, and it is the policy and practice of the University of Washington to create inclusive and accessible learning environments consistent with federal and state law. Disability Resources for Students (DRS) offers resources and coordinates reasonable accommodations for students with disabilities. If you have not yet established services through DRS, but have a temporary or permanent disability that requires accommodations, you are welcome to contact DRS at 206-543-8924 or  or visit disability.uw.edu.

Quiz/Exam Accommodations

For the Preparation for General Chemistry and General Chemistry courses, it is the Department of Chemistry's practice to have students with exam accommodations take their exams in the DRS Testing Center. If you have already established accommodations with DRS, the information for the Alternative Testing Contract will be submitted to DRS via their online system. Questions regarding the online submission of the alternative testing request and contract should be directed to the Disability Resources for Students Office (, MGH 011).

IMPORTANT NOTES: Students with exam accommodations are solely responsible for scheduling the exams with DRS well in advance of the exam dates. Since the testing center has a limited capacity, please be sure to schedule ALL of your chemistry exams (including the final exam!) as early as possible in the quarter so that the DRS office can accommodate you. Students not scheduling far enough in advance to secure a testing reservation will need to take the exam in the classroom at the regular class time with the rest of the class and will only have available the standard 45 minutes in which to take the exam.

RELIGIOUS ACCOMMODATIONS POLICY 

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, can be found on the Religious Accommodations Policy page. Accommodations must be requested within the first two weeks of this course using the Religious Accommodations Request form.

COURSE MATERIALS & REQUIRED CONNECTIVITY

Except where indicated, all items are required and available from the University Bookstore.

COURSE COMPONENTS AND GRADING

The course consists of:

  • Several pre-recorded lessons per week – Panopto Recordings already posted on Canvas
  • 2-3 class sessions per week, focusing on content discussion and problem-solving. In person attendance at these sessions is strongly encouraged, but optional. Class will be livestreamed and recorded via Panopto for those who cannot be present in person. 
  • 1 in person discussion section per week in Weeks 2-10
  • 1 in person three-hour laboratory session certain weeks of the quarter (6 labs total See the 152 Laboratory Resources page of the course website for details.) 
  • Daily work in the ALEKS online learning environment
  • Online prelab assignments and online submission of post-lab reports, delivered via Canvas
  • 3 in person exams, delivered in Weeks 3, 6, and 9 during the regularly scheduled class sessions in BAG 131. 
  • 1 in person final exam, delivered on Tues, Mar 14 at 8:30-10:20 pm am in BAG 131.

TOTAL

100%

Active Reading Assignments (2%)

There will be an Active Reading Assignment in advance of each class day for which you have an assigned reading. Each Active Reading Assignment will be worth 2 pts. The goal of these assignments is to give your brain the "big picture" of what it's about to learn, which will increase your ability to retain the information and subsequently build on it in class. Learn more about these assignments here: Active Reading. Active Reading Assignments are graded on completion only. The three lowest Active Reading scores will be dropped, allowing you to miss a few without penalty. 

Surveys (2%)

These surveys will guide you through a reflection on your exam preparation strategies, and an analysis of your performance and the strategies that work best for you in learning the material for this course. Engaging with the survey questions sincerely will help you  build metacognition, a mental skill that allows you to keep track of which study habits work and which don't. There will be six Exam Reflection Surveys total: three Pre-Exam Reflections, and three Post-Exam Reflections, distributed throughout the quarter. (Note that there will not be a pre- or post-exam reflection for the final exam in this course.) Each Exam Reflection Survey is worth 2 pts. All Exam Reflection Surveys will count towards your score. 

This category also contains a Research Survey assignment. This survey is part of a research project on active learning techniques in large-enrollment STEM classes. (More details will be posted later in the quarter before the survey opens.) This assignment is graded on completion only. The members of the Teaching Team for this course will never know how you responded to the survey questions, only whether your completed the survey or not. You may elect to have your data and responses to the questions omitted from the research study. However, completing this assignment is a requirement of this course. The Research Survey is worth 2 pts. If you choose not to complete this survey, you will earn 0/2 points for this assignment. 

Discussion Section Participation (2%)

Discussion section will be conducted in person during the regularly-scheduled discussion section time. To earn your participation credit, you must arrive on time and participate in good faith during the Discussion Section, not simply be in attendance. Each Discussion Section is graded out of 3 pts:

    • 1 pt for arriving on time
    • 2 pts for participating in good faith

The two lowest Discussion Section scores in Weeks 2-10 will be dropped, allowing you to miss two without penalty.

ALEKS (13%)

Your ALEKS grade is constructed from your objective scores and the percent of the pie you complete by the end of the quarter. The more of the pie you complete, the higher your ALEKS score will be, but you do not have to complete the entire pie to earn some credit for ALEKS. Similarly, you do not have to complete all the topics in an Objective to earn some credit. Whatever percentage of topics you complete by the due date will be your score for that Objective. The number of topics is not the same in every Objective; we endeavored to make your load lighter in weeks with a quiz. The Objective and Pie Mastery portions of your ALEKS grade are weighted equally. They each represent 6.5% of your overall course grade. 

Laboratory (15%)

Your Laboratory grade is comprised of six prelab quizzes (5 pts/ea), six postlab reports (60 pts/ea), the Undergraduate Stockroom contract (5 pts), and the Safety Quiz (5 pts). All of the lab activities will count towards your score. More details about lab can be found on the 152 Lab Canvas page.

Midterm Exams (42%) and Final Exam (24%)

Graphing or text-entry calculators WILL NOT be permitted on exams.

A list of equations, constants, and conversion factors will be provided with exams. Students will not be permitted to bring their own list of notes or equations to exams.

There are three midterm exams in this course. Each exam will focus on the most recent set of lessons, but chemistry knowledge is cumulative by nature, so the questions will often depend on knowledge from earlier chapters and prerequisite courses. Information about exam length, format, and coverage will be posted in the Exams module as each exam date nears. The dates for the exams are provided in the course schedule on Canvas. 

The lowest score among the three midterm exams will be dropped. This drop policy encourages you to quarantine if you are sick, even if the quarantine period occurs on as exam day. Please do not come to class or to an exam if you are sick. If you have an excused absence on a midterm exam, your missed exam score will be replaced with your score on the final exam. 

Exam keys will be available on Canvas after grading has been completed, except for the final exam which will not be published. Scores for the final exam will be posted in the Canvas gradebook. You may make an appointment with me next quarter to view your responses and grading details for the final exam.

Grade Distribution

The final mean GPA in Chemistry 1x2 generally falls within the range 2.6-2.9. It is the Chemistry Department’s policy not to make grade changes of 0.1 after final class grades are submitted to the UW Registrar.

How course grades are calculated: I will use the equation of a line between (~98%, 4.0) and (~40%, 0.7) to convert course percentages into GPs. When I do this, the average grade tends to fall in the range 2.6-2.9. I do not set the average to fall in this range. This means your grade in the course does not depend on anyone else's grade! Grades in this class are not zero sum. 

Monitor your Scores

Your scores for Participation, Lab, and Exams  will be recorded using the Canvas Gradebook. Your ALEKS scores can be monitored through the Gradebook and Reports tabs on ALEKS. Your overall ALEKS grade will be imported to the Canvas Gradebook at the end of the quarter.

ACADEMIC ETHICS

Original work performed in good faith is assumed on all assignments and course components.

The Student Conduct Code prohibits several forms of academic misconduct (see section 7: Prohibited Conduct), including:

  • Cheating
  • Falsification
  • Plagiarism
  • Unauthorized collaboration
  • Engaging in behavior specifically prohibited by an instructor
  • Recording and/or dissemination of instructional content without express permission of the instructor

You are required to sign and submit an honor code statement for this course, in which you will affirm your acknowledgment of what constitutes academic misconduct in this course as defined below. Failure to adhere to this code of ethics will result in referral for possible disciplinary action as described in the Student Conduct Code.

General policies for all course assignments

Your submissions for ALL assignments (including but not limited to homework assignments, lab reports, quizzes, and exams) should be your own individual work unless you are explicitly told otherwise by your instructor.

You are strictly prohibited from sharing any content from ANY assignment (including but not limited to homework assignments, lab reports, quizzes, and exams) with any website or app (including but not limited to Discord, Chegg, Course Hero, and Snapchat) or any other course content repository (virtual OR physical) that is not explicitly approved by the instructor. This prohibition applies both during the quarter that you are taking this course and any time after the course ends.

Specific policies for exams and quizzes

During exams and/or quizzes, you may not seek out or accept any input from ANY other individual, whether or not they are a classmate. Further, you may not provide assistance to other students during the availability window for an exam or quiz unless an instructor explicitly allows for that collaboration.

Specific policies for lab reports

It is presumed that the data you record and report in laboratory is your work. All data analysis and written/typed calculations and responses that you submit should be yours alone, even if you collected data with a laboratory partner. We often find examples of plagiarism in which lab reports are copied from someone else, or from an earlier quarter and examples of improper collaboration in which lab reports or portions of lab reports are posted or shared for other people to view.

We understand that it can be difficult for students to discern what constitutes good-faith collegial support on lab reports, and what constitutes plagiarism or cheating. While we often find examples of explicit plagiarism in which lab reports are directly copied from a student in the current quarter or an earlier quarter,​ we also find many cases of students “over collaborating,” resulting in reports that are essentially identical or extremely similar with only minor edits made to achieve minimal differences between the reports. This does not meet our expectation that you are submitting your own independent work. In short, if you have not done something yourself, do not attempt to pass it off as original work. If you have questions about what might cross the line, please do not hesitate to ask your lab or class instructor prior to submitting your work. You will not get in trouble for asking this type of question!

CLASS SESSIONS

Video Lesson Content

Formal lesson content will be delivered via Panopto recordings. 

A schedule for the chapters to be covered each week is available in the Canvas calendar for this course. You are responsible for material covered in class AND in the textbook (whether or not it was covered in the lesson videos). The Lessons will cover only highlights of the textbook material.

In-Person Review & Problem-Solving (R&P) Sessions 

During the regularly scheduled class time, we will engage in learning activities to further and deepen your understanding of the material presented in the video lessons. These activities will help you review the content from the video lessons, and help you build your problem-solving skills. I will respond to the evolving needs of the class in terms of how these sessions are structured.

PDFs of the activities presented in each class will be available on the Unit modules. All in-person lessons will be recorded using the Panopto lecture capture system. 

Attendance at the in-person class sessions is strongly encouraged, but not required. I will employ Poll Everywhere activities to keep the sessions engaging, but these polls will not be graded. If you don’t plan to pay attention during an in-person session, don’t come, because you will distract other students. These sessions will all be recorded and made available on Panopto, so you can watch them at your leisure.

DISCUSSION SECTION

The primary activities during the weekly in-person Discussion Sections will include:

  • The TAs will field your questions about lab, quizzes, course content, etc.
  • You will work with your colleagues on worksheet problems relevant to current course topics.

Weekly worksheet problems are intended to help you synthesize the material covered in the previous week’s lectures, therefore, they will be quite challenging. A blank version of the worksheet will be available at least a week in advance of each Discussion Section. You can find the worksheets in the relevant unit module. The worksheet key will be available on Tuesday evening each week.

In-person participation during the Discussion Sections is required. To earn participation credit, arrive to discussion section on time and collaborate in good faith with your colleagues. If you arrive late, or if you engage in activities unrelated to the course, you will not be awarded participation credit for that day. 

You may miss two Discussion Sections without penalty.

ONLINE LEARNING (ALEKS)

This course uses the internet-based learning program ALEKS (Assessment and LEarning in Knowledge Spaces). In ALEKS, you will complete learning objectives rather than traditional homework assignments. An ALEKS Objective contains topics relevant to the lecture discussions. ALEKS will present you with a series of problems that explore a particular topic. The problems will have enough variability that you will only be able to get them consistently correct by understanding the core principle or skill defining the topic. Once you consistently answer the problems for a given topic correctly, ALEKS will conclude that you have learned the topic, and you will then be allowed to choose another topic to learn (refer to the ALEKS Orientation posted on the course website for more details). Your daily/weekly work on ALEKS will be on your own schedule outside of class, although there are specific deadlines by which you must complete various Objectives.

The registration code for your ALEKS course can be downloaded from ALEKS module in Canvas. 

Your first task in ALEKS will be to complete an Initial Knowledge Check. This is ALEKS’s way of assessing your current knowledge of math and chemistry, so that it can guide you appropriately. The Knowledge Check will contain 25-30 questions and shouldn’t take more than 40-60 minutes to complete. You will probably be asked a few questions that you don’t know how to answer. Don’t worry…the ALEKS system is only determining your knowledge baseline so that it can be tailored to address your specific needs. When you use ALEKS, you will complete the learning tasks you need and not those somebody else needs. After you complete the Initial Knowledge Check, ALEKS will provide one-on-one instruction intended specifically for you. ALEKS will also give you a new Knowledge Check after you complete each Objective, so that it can track your evolving knowledge state as you move through the material, and continue to tailor its approach to your unique learning path.

You, alone, are responsible for monitoring the due date and time for all ALEKS Objectives. Note that it is not possible to open up an ALEKS Objective 3 or 4 hours before it’s due and be able to complete it. ALEKS will not let you access the problems corresponding to the more advanced topics in an Objective until you have mastered the basics, so you will need to spend time nearly every day on ALEKS to complete the Objectives. The schedule of Objectives and their due dates is available on the Canvas course site.

KEYS TO SUCCESS

  1. Participate in ALL available sessions, pay close attention, and take notes. 
  2. Learning chemistry is a sequential process. You must understand today’s material before you can understand tomorrow's. As with all courses at UW, your instructors and TAs will assume that you are studying at least two hours for each hour of lecture and one hour for every hour of lab. Find a place that allows for periods of uninterrupted study. Skim through chapter or sections to be covered in the next lecture.
  3. Working in shorter, more frequent sessions in ALEKS will be more efficient than long, marathon sessions.
  4. Practice! Work on suggested end-of-the-chapter problems as well as topics in ALEKS - focus on understanding the concepts and general processes, not just memorizing how to solve a specific problem.
  5. Talk chemistry with fellow Chem 152 students. You will not only learn more, but you will probably also enjoy the course more. This is a much bigger challenge with remote learning, but also so much more important when there are not in-person sessions. Use the discussion board, chats, etc. to create study groups for talking about the course content.

WHERE TO GET HELP

  1. Ask questions in person during class, discussion section, or help sessions / office hours.
  2. Ask questions on course discussion board. While you are there, take a look at your classmates’ posts and see whether you can help them. Learning happens when people share experiences, knowledge, and ideas.
  3. Form your own study group. Try using the course discussion board to find interested classmates. You have your own Zoom account, so you can even connect virtually to discuss the course!
  4. The Center for Learning and Undergraduate Enrichment (CLUE) offers free drop-in tutoring and exam reviews for Chemistry. See the Academic Support Programs website for more information.
  5. The Instructional Center offers free drop-in tutoring, review sessions, study skills seminars, and more for students who are members of TRIO or EOP (students who are not members of TRIO or EOP may apply to access IC services on a space-available basis). For more information, visit the IC website.
