Course Materials

Lecture Slides Course Pack (purple): Contains all of the lecture slides to facilitate taking notes and working the example problems in the video lectures. Available on campus at the Texas Union or by mail from Document Solutions. (250 pages spiral bound, $23.76 + shipping)

Practice Problems Course Pack (orange): Contains all of the worksheets for the weekly discussion sessions, the four unit exams from last year with solutions, and practice problems with solutions to help you learn the course concepts. Available on campus at the Texas Union or by mail from Document Solutions. (400 pages spiral bound, $29.26 + shipping) There is not a printed general chemistry textbook for this course. Instead our primary content resource is the gchem web site, which is a free online chemistry textbook developed by professors at UT specifically for use with CH301 and CH302. Other free online chemistry textbooks include OpenStax Chemistry from Rice University and Chemistry LibreTexts from UC Davis. You will also need a scientific calculator for this course. It must be able to do scientific notation and logarithms. Any scientific calculator is allowed. 1

CH301 Course Content CH301 is made up of four units aand covers the first six chapters on the gchem web w site.

Unit 1 – Gases (Aug 26-Sept 17)) The semester begins with a brief review of Fundamentals (Chapter 1) follow wed by the study of gases (Chapter 2). We will discuss the behavior of gases, thhe ideal gas law, kinetic molecular theory, gas mixtures, and how to handle reaal gases that deviate from the ideal gas law.

Unit 2 – Atomic Theory (Sep 18--Oct 8) In Unit 2 (Chapter 3) we will learn how the interaction between light annd matter revealed the internal structure of the atom and led to the developmennt of the field of quantum physics. We will also cover quantum numbers, electro on configurations and electron orbitals, and end the unit by looking at perioddic trends and how to predict certain properties of elements just by lo ooking at their positions in the periodic table. Unit 3 – Bonding & Intermolecuular Forces (Oct 9-Oct 29) Unit 3 explores the different kinds of chemical bbonds that are formed when atoms with different properties combine to form molecules. This topic includes molecular shapes and chemical bbonding theories that allow us to predict certain properties of molecules ((Chapter 4). The interactions between neighboring molecules determin ne key physical properties such as melting point and boiling point. Understaanding these intermolecular forces (Chapter 5) helps us predict key behaviors of chemical substances. Unit 4 – Thermodynamics (Oct 330-Nov 19) Thermodynamics (Chapter 6) is the study of the movement of energy in physical and chemical changes. In this final unit we'll le earn why some chemical reactions happen while others don't, and h how to calculate how much energy is absorbed or given off by various chemical and physical changes. Comprehensive Course Review (Nov 20-Dec 7) The last week of class will not introduce any new material. Insttead this time is reserved for reviewing the material of all four units in prepaaration for the cumulative final exam. We will have opportunities for you to as k questions and get help on any concepts you feel you need to review.

CH301 Online Course Overview CH301 is a mix of synchronous and asynchronous online work. If you have a conflict with the synchronous portions of the course we will do our best to provide alternative times.

Learning Exercises (asynchronous) The Learning Exercises are how you "come to class" in this online course. The class lectures will be posted as videos that are each part of a larger online Learning Exercise (LE). You will have multiple LEs due each week. An LE is usually a single-topic lesson, and each LE can include a mixture of: • • •

some short background reading. a few problems where you can practice what you learned. a video lecture that is anywhere between 15 and 30 minutes long.

The video lectures include moments where you will stop the video to work out problems, so expect the video portion of the LE to take longer than just the actual time required to watch the video. At the end of each LE there are links to the relevant sections in our gchem site.

Homework Assignments (asynchronous) The Homeworks (HW) are longer problem sets, typically around 30 problems that help you test your understanding and figure out which concepts and skills need more practice. You will typically have 2-3 HW assignments per unit.

Discussion Groups (synchronous) Once each week you will participate in a one-hour class for small group work. You may be assigned a session during your scheduled class time or one offered at a different time – we use a scheduling survey to ensure everyone is assigned a weekly time that fits their schedule. At the end of each session you will upload a photo of your work for grading.

Quizzes (synchronous) There will be weekly online quizzes on Thursday evenings at 5:00 PM Austin time. If you have a conflict with this time you must submit this form immediately so we can schedule another time for you.

Final Exam (synchronous) The final exam schedule will be announced once it has been determined. All sections will take the final exam at the same time (an alternate time will be provided for students who have time conflicts).

Where to get help Office Hours Professors and TAs will hold office hours via Zoom at various times throughout the week. Check Canvas for a complete schedule. You can attend any office hour listed, even if it is another professor.

Supplemental Instruction (SI) The Sanger Learning Center has provided four Supplemental Instruction Leaders who will each lead a weekly Zoom session to provide extra practice and extra instruction in the course material. The SI leaders are former CH301 students who excelled in this class and are here to help you succeed as well. Regular attendance at SI sessions is an excellent way to practice and improve your concept understanding and problem solving skills. The weekly SI session schedule is available via a link on the Office Hours page in Canvas.

Piazza Piazza is an online question and answer forum that students can use for asking chemistry-related questions outside of office hours. If you have a question about chemistry content, please do not e-mail your instructor or TA! Post the question on Piazza instead – that way other students can also benefit from seeing the answer. You can ask questions and also answer other students' questions anonymously on Piazza. Your questions and answers on Piazza can be anonymous to other students if you choose. You will receive an e-mail invitation to join Piazza. If you do not receive an invitation, go to https://piazza.com/utexas and follow the instructions to sign up.

SSD students If you are a student registered with the Office of Services for Students with Disabilities and receive special accommodations for exams, we will apply these accommodations to the class quizzes. Please fill out this form ASAP so we can make sure your needs are met. Also notify your instructor of any other modifications or adaptations you may require to accommodate a disability-related need.

Observance of Religious Holidays Religious holy days sometimes conflict with class and quiz schedules. It is the policy of The University of Texas at Austin that the student must notify each instructor at least fourteen days prior to the classes or exams scheduled on dates he or she will be absent to observe a religious holy day. For religious holidays that fall within the first two weeks of the semester, the notice should be given on the first day of the semester. The student may not be penalized for these excused absences but the instructor may appropriately respond if the student fails to complete satisfactorily the missed assignment or examination within a reasonable time after the excused absence.

Academic Dishonesty Cheating and penalties If you get caught cheating in any way whatsoever you will have to discuss the situation with us. We will decide on a penalty and write up a formal report that goes into your permanent file in the Office of the Dean of Students. The minimum penalty for cheating is receiving a 0 on the assignment on which you cheated, but harsher penalties are likely to be assigned. For more information, read about scholastic dishonesty in the General Information Catalog.

Open book quiz restrictions The online quizzes are open book and open note tests. You may also use the Internet while taking the quizzes, however you may not post a screenshot or say anything that invites someone to offer help answering that question. Making use of existing online resources is fine – this includes going to gchem, OpenStax, YouTube, etc, and seeing what information is already there. But you may not post anything on sites like Chegg or solicit help from anyone (other than an instructor or TA from this class) online, in person, or over the phone. If Chegg sees that you are posting exam questions, they will give your entire posting history from their site to the Dean of Students' office and you will receive an F in the course. However, neither the dean nor Chegg will explain to your parents why you failed CH301 and have to take it over again next semester. You get to do that yourself. If you have any questions about what counts as cheating, feel free to e-mail any of the instructors or go to the website for Student Conduct and Academic Integrity in the Office of the Dean of Students.

Sharing of course materials online is prohibited. No materials used in this class, including but not limited to lecture hand-outs, online videos, assessments (quiz questions, exam questions, papers, projects, homework assignments), in-class materials, review sheets, and additional problem sets, may be shared online or with anyone outside of the class unless you have the explicit, written permission of your instructor. Unauthorized sharing of materials promotes cheating. It is a violation of the University’s Student Honor Code and an act of academic dishonesty. We are well aware of the sites used for sharing course materials, and any unauthorized sharing of CH301 materials will be reported to Student Conduct and Academic Integrity in the Office of the Dean of Students. These reports can result in sanctions, including receiving an F in the course, even if the material is discovered long after the course is over.

Read this before you need this! In high school you were in class all day and were surrounded by adults. Under normal circumstances, in college you are in class for only a few hours each day. This is because in high school the burden of teaching is on the teacher, and in college the burden of learning is on the student. Now YOU are the adult, and it is your responsibility to make sure you are learning. In CH301 we cover far more material in many fewer hours than a high school chemistry class does. For most students, coming to class (or watching the videos) is not enough! Those extra hours in your schedule each day are not free time, they are flex time for you to use according to your own individual learning needs. Many of you are facing an additional challenge because making this transition toward more independent learning is difficult to do in a home environment. We are here to help!

Before you begin to struggle •

Attend office hours. Office hours are not just for students with questions or students who are struggling. Office hours are part of the learning experience in college. You can see the list of office hours on our Canvas site, and you can attend any of these. Each professor or TAs office hours will be a little different, so if the first one you try isn't what you're looking for, try another one till you find one you like. This is the number one piece of advice we give to struggling students. Don't wait until you're struggling to do this. Attend Supplemental Instruction sessions. These are not the same as office hours. The onehour SI sessions are led by former CH301 students now working for the Sanger Center and include some teaching as well as in-class practice answering questions and solving problems. For many CH301 students, peer-to-peer instruction is the most effective way to learn. Actively participate in your small groups. Your fellow students and learning assistants are available to help you at these times. This is a collaborative, not competitive course – by helping each other with the material, you will learn it better yourself. Ask and answer questions on Piazza. This is where all content-related questions should be asked if you can’t make it to office hours. You will learn a lot by answering questions posted by other students. You should not post a full solution, but give them some hints to guide them in figuring out the next step. We highly appreciate students who answer questions and we might even have some rewards for those of you who answer the most. Remember, all content questions should be asked in office hours or on Piazza. If you have a personal question, please do not use the messaging system in Canvas. You will get a faster response using the e-mail address listed in the syllabus.

LET US KNOW! We can help. The Sanger Learning Center offers useful advice on studying and note-taking techniques in general, as well as tutoring in chemistry. Many of their services are also offered online. We encourage you to try our own office hours first, but Sanger can be a great resource for extra help. COVID-19 has led to increased anxiety and depression even in those who never experienced it before. If stress is interfering with your ability to complete your class work or even if you just need someone to talk to, contact the Counseling and Mental Health Center at 512-471-3515.

Drop Date The last day to drop the course is Thursday October 29. If you wish to drop the course, you will need to contact your college to initiate the process. The last day to use your One-Time Exception drop is Monday December 7.

Degree requirements CH301 carries the Quantitative Reasoning flag. Quantitative Reasoning courses are designed to help you develop the skills necessary to recognize and solve real-world calculational problems. You should therefore expect a substantial portion of your grade to come from your use of quantitative skills to analyze and solve problems.

Core Curriculum Requirements & Objectives CH301 may be used to fulfill three hours of the natural science and technology (Part I or Part II) component of the university core curriculum and addresses the following four core objectives established by the Texas Higher Education Coordinating Board: communication skills, critical thinking skills, teamwork, and empirical and quantitative skills. Communication Skills Students will work in class, on homework, and on exams to apply scientific models to explain empirical data as well as to use models to predict physical and chemical change. Students will be able to connect mathematical formulas and graphical representations to communicate scientific concepts. Critical Thinking Students are presented with many opportunities to use critical thinking skills to solve problems both in class via the classroom polling system and on graded homework assignments. These skills are assessed on the exams. Teamwork Students work in small groups in class on guided group activities designed to help the student come to a deeper understanding of the content and to "discover" chemical principles via the process of inquiry. Outside of class students are encouraged to continue working in groups on better understand homework assignments. Quantitative Skills Students are required to calculate answers based on their understanding of scientific laws and derived equations. These methods include skills in manipulating units, understanding and applying the concept of ratios, proportionality, rearranging algebraically to solve for a specified unknown, understanding and applying rates of change, and interpreting equations using physical models. These skills are assessed on the exams.
