Chemistry Course Content
CH302 is broken down into four equal units that each cover a different fundamental area of chemistry. The title of each unit is linked to the relevant section of the eBook that contains the specific learning outcomes for each unit.
Unit 5 - Physcial Equilibria This unit will examine the concept of equilibria and free energy in the context of physical change. Specifically we will examine phase transitions and the thermodynamcis of solutions and solubility.
Unit 6 - Aqueous Equilibria This unit will examine free energy in the context of chemical change with an emphasis on the chemistry of aqueous solutions. In particular we will examine acid/base equilibria in the context of weak acid/base buffer systems.
Unit 7b - Kinetics We will skip the nuclear portion of this unit. For chemical kinetics we will look at the rates of chemical change specifically addressing the factors that control the rates of chemical reactions. We could have some nuclear examples in the kinetics chapter but it will be under the context of kinetics.
Unit 8 - Electrochemistry
The final unit is a capstone unit for the entire semester and examines free energy, equilibria, and solution chemistry in the context of electrochemistry. Specifically we will examine oxidation reduction chemistry and electrical potentials for applications ranging from sensors to batteries.
Requirements
TopHat:
All students must have a "smart" device in class and run TopHat software. This is a replacement of our traditional iClicker. This software allows the student to use any wifi connected device for their in-class responses. This includes smartphones (both Android and iOS), tablets, iPods, and laptops.
eBook (cost: FREE) All of our topics are covered in our online FREE ACCESS eBook. We wrote it, we control it, and you have 24-7 access to it. It works on desktop computers, laptops, tablets, and phones. If it has a modern browser you are in business. However, if you really want a hardcopy book, we suggest you purchase a used Chemical Principles type textbook. Some solid books that we have reviewed are the 4th, 5th or 6th edition of Chemical Principles, by Steven S. Zumdahl; Chemical Principles by Atkins & Jones, 3rd, 4th or 5th editions; Principles of Modern Chemistry by Oxtoby, et al, 4th, 5th or 6th editions. These books are all a solid resource for further reading. Once again, these books are not required, buy you might find them very useful in your studies.
Here is more information on our textbook policy for CH301 and CH302.
Calculator: For exams you need to have a nonprogrammable, scientific calculator. You should be able to pick one up for around $15.00 anywhere that sells school supplies. I would avoid a solar powered calculator as you can't count on good lighting in the exam rooms. You can never use a programmable calculator or a wireless device as a calculator during an exam .
Sapling Learning (cost: $25)
This course makes use of the web-based homework system from Sapling Learning. The setup and registration for Sapling should now be available and doable via our Canvas site. This service will require a $25 charge per student for its use. There is a 14 day grace period for payment. After that date you will no longer be able to access required homework for the course. BTW: If you were a registered Sapling user for the Spring of 2014, your are still registered and do not have to pay anything because your Spring 2014 carries over into the Summer session.
Overall Scoring for the Course
We will use six aggregate scores that we will use to get your over all score in the course. Here is the run down of the six numbers we will use.
- 3-Exam avg: average of your best 3 of 4 exams (one drop)
- Final exam: score on the final exam
- Homework: average of the best 10 of 12 homeworks (two drops)
- LM Quiz: average of the best 30 of 34 LM quizzes (four drops)
- TopHat: score for TopHat as a percentage of max points possible
- lowest exam: lowest of four exam scores (the dropped one)
Your overall score is calculated to give you the highest score possible within the confines of our allowed percentages and drops within each category. The following table is an effective way to see how to get your overall score in the class. There are too many "if/then" scenarios to list each one separately. So this is a rubric to use to figure out your score.
| category / criteria | weight |
|---|---|
| 3-exam avg | 55 % |
| final exam | 25 % |
| Higher? 3-exam avg or final exam | 5 % |
| highest of 2-6 above | 5 % |
| second highest of 2-6 above | 5 % |
| third highest of 2-6 above | 5 % |
| total | 100 % |
Notice that this means that your final exam could count as much as 35% towards your overall grade. In general, the easiest categories to score high in are homework, learning modules, and TopHat. Staying engaged with the class and staying on task will help you score very high in those three categories. If for some reason you do not do the assigned homework, etc., then you still have your exam scores to fall back on for your grade.
Grade Breaks
Course grades will be determined according to the following scale or cut-offs:
| A | ≥ | 93.00 |
| A- | ≥ | 90.00 |
| B+ | ≥ | 87.00 |
| B | ≥ | 83.00 |
| B- | ≥ | 80.00 |
| C+ | ≥ | 77.00 |
| C | ≥ | 73.00 |
| C- | ≥ | 70.00 |
| D+ | ≥ | 67.00 |
| D | ≥ | 63.00 |
| D- | ≥ | 60.00 |
| F | < | 60.00 |
Your score is calculated to the nearest 1/100th - that's 2 places PAST the decimal. So the only digit that is rounded "up" is the 1/1000th's digit.
Exams
Four examinations will be given during this short semester. These will be given during class time every 6 lecture days (5 days and then an exam). Please see the Canvas site for the calendar that has these placed. Each of the exams will be all multiple-choice questions - the number of choices will vary anywhere from 2 up to 10 choices. Each student will turn in their exam copy and a bubblesheet (answer sheet) which will be scanned and graded. All scores on exams will be available on Canvas after the grading is done.
Final Exam
The final exam WILL be comprehensive. This means that all the material covered during the course will be on the exam. The final exam will be counted as 25% of your overall grade. This could be more if the score is high enough - see "Overall Scoring for the Course" above for details.
The final exam schedule is set by the Registrars office and cannot be changed. It is scheduled for Friday, 7/11, from 7-10pm in our regular classroom, WEL 2.122.
Exam Schedule
The class exams will be held in our classroom (WEL 2.122) on the scheduled days below. There will be assigned seating in order of version number. Your version number will be delivered to your via Canvas. Look for an assignment named "exam#-version" a few days before the exam.
- Exam 1 Mon 6/16
- Exam 2 Mon 6/23
- Exam 3 Tue 7/1
- Exam 4 Wed 7/9
- Final Fri 7/11 (7-10pm WEL 2.122)
Work in the Class
In Class Stay Fully Engaged
Opportunities to test your prior knowledge, your progress on the learning curve and your mastery of chemical principles will be given in class using TopHat. These opportunities will come in the form of in-class TopHat questions. Each clicker question is worth 5 points (3 for just answering and 2 more points for getting it right). On any given day in class, we might have as few as one question and as many as ten questions. TopHat does sync with Canvas and your overall average in TopHat will show in Canvas. You can also see all the details (every question asked) in TopHat. It is very important that you remember to bring your "device" so that you can answer questions and get credit this way. A fully engaged student who attends class regularly will have an TopHat score in the mid 80's to high 90’s, assuming you typically get questions right. Anything considerably less than this indicates something is not quite "right". The score from TopHat will be 5% of your overall score (most likely, see details in the "Scoring" section above).
Work Outside the Class
Online Work
We will be using Sapling and Canvas for online learning and assessment. There are two types of graded assignments: Learning Module Quizzes and Homework. LM Quizzes will be on Canvas and they are designed to introduce new concepts and/or direct teach basic skills outside of class. Homework Sets will be from Sapling and they are a series of problems that you should work through to help you solidify your conceptual understanding of the material and to develop more sophisticated problem-solving skills. Skill drilling worksheets are available from in the eBook but are not graded. The drilling worksheets are designed to help build your problem solving skills such that you can successfully complete your homework. Each type of assignment has been designed for a particular purpose to help you master the learning outcomes for this course. To this end, each assignment should be completed in the order in which it was assigned. Learning Modules and their associated quizzes will typically be shorter than the homework assignments. The graded LM quizzes and homework will be counted toward your overall grade at 5% each. Each LM quiz can be repeated three times. Your highest score will be counted toward your grade.
More about the Exams
Be sure and bring your approved calculator to the exam. I cannot provide calculators. You CANNOT use your cell phone or any other device as your calculator. Each student will receive a unique exam copy with a specific version number on it. There is a different exam version for every student in the class; no two students can have the same version numbers (it is impossible). We will keep ALL exam materials after the exam is over. You MUST turn in your exam, a bubblesheet, and all scratch paper when you complete your exam. Make sure you sign each part of your exam.
You CANNOT make-up a missed exam for ANY REASON WHATSOEVER. If you have a University approved conflict that requires rescheduling an exam, you must notify the instructor within the first 2 weeks of the course (go to WEL 2.212 and schedule your earlier exam time). You get to drop one exam score from your overall average, so for whatever reason you miss, that particular exam score (a zero) will be your dropped exam.
More About the Final Exam
We will not allow you to take the final early, late, or with another section.
A final exam cannot be made-up in any way. Final exam times are scheduled by the registrar's office and cannot be changed for any reason. Show up at the right place and the right time (Friday, 7/11 from 7-10pm) or get a zero on the exam. The final exam WILL be comprehensive. This means that all the material covered during the course will be on the exam. The final exam will be counted as no less than 25% of your overall grade (could be more if you make higher than other scores). If you keep up with the material for the semester, the final will not be any more difficult than the four exams. It will be extremely difficult if you try to cram for it one day ahead. Keep up and make the grade. The time for the final is published when the course schedule is made, but it is subject to change, so double check the time for the final the week before the final exam.
Cheating
If you get caught cheating in any way, whatsoever, you will have to discuss the situation with us. We will arrive at a penalty and write up a formal report. The minimum penalty for cheating is receiving a 0 on the assignment on which you cheated. In this class, in addition to all the traditional types of cheating (looking at someone else’s answer, utilizing “cheat sheets” of any form or fashion – paper or digitized, getting an advance copy of an exam or quiz), we also consider allowing someone else to enter answers in class with your phone or tablet cheating. For example, if you send your iPhone to class with another class mate or an individual who is not you and you are caught, you and your accomplice will be penalized. If you deny the allegation, we will proceed by filing a formal report to the Judicial Services in the Dean of Students Office as is policy. Judicial Services would decide the final penalty after a hearing on the matter. For more information, read in the General Information Catalog about scholastic dishonesty (i.e. cheating).
Students with Disabilities
Please notify me of any modification/adaptation you may require to accommodate a disability-related need. You will be requested to provide documentation to the Dean of Students' Office, in order that the most appropriate accommodations can be determined. Specialized services are available on campus through Services for Students with Disabilities. The official wording is this: The University of Austin provides upon request appropriate academic accommodations for qualified students with disabilities. For more information, contact the Office of the Dean of Students at 471-6259, 471-6441 TTY or Division of Diversity and Community Engagement, Services for Students with Disabilities, 512-471-6259, www.utexas.edu/diversity/ddce/ssd
Drop Date
The last day to drop the course is July 10, 2014 (last day of class). This will require you to go to your college and get a drop form. You then must bring the form to me and get my approval and signature. After this deadline, students must go to the Dean's office, WCH 2.112, to begin the appeal for substantiated non-academic reasons.
Observance of Religious Holidays
Religious holy days sometimes conflict with class and examination 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 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.
How can I be prepared for an emergency?
Occupants of buildings on The University of Texas at Austin campus are required to evacuate buildings when a fire alarm is activated. Alarm activation or announcement requires exiting and assembling outside. Familiarize yourself with all exit doors of each classroom and building you may occupy. Remember that the nearest exit door may not be the one you used when entering the building. Students requiring assistance in evacuation shall inform their instructor in writing during the first week of class. In the event of an evacuation, follow the instruction of faculty or class instructors.
Do not re-enter a building unless given instructions by the following: Austin Fire Department, The University of Texas at Austin Police Department, or Fire Prevention Services office. Behavior Concerns Advice Line (BCAL): 512-232-5050
Does this course carry a FLAG?
You betcha... Quantitative Reasoning
This course carries the Quantitative Reasoning flag. Quantitative Reasoning courses are designed to equip you with skills that are necessary for understanding the types of quantitative arguments you will regularly encounter in your adult and professional life. You should therefore expect a substantial portion of your grade to come from your use of quantitative skills to analyze real-world problems.
Core Curriculum Requirments
This course 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 model 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 Thinkings
Students are presented with many opportunities to use critical thinking skills to solve problems both in class via clicker response 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, interpreting equations using physical models. These skills are assessed on the exams.
