Q&A Sessions:

Tuesdays 4–5 pm (ROOM TBA) Wednesdays 12:30–1:30 pm (ROOM TBA)

These sessions will provide opportunities for extra problem solving. If you have a question about any material covered in the course, please attend these sessions. Review sessions will also be scheduled each exam week. Office Hour:

Mondays 4:30–5:00 pm (Kenan C-441)

This time is reserved for discussion of administrative matters, logistics and course success. Email Policy:

Prof. Dempsey has limited availability by email. No chemistry content questions will be answered by email. When emailing Prof. Dempsey, please: 1. Include “CHEM101” and a one-word description in the subject line (e.g. CHEM101 clicker) 2. Keep your message brief and direct. 3. Expect a 36 hr. turn-around time.

Chem 101 Course Structure Chem 101 will utilize a modified version of the ‘flipped classroom’ teaching model this semester. In this approach, the traditional lecture-in-class/work-problems-at-home structure is inverted. Before each class, you will have a Mastery Learning Assignment (MLA) which will introduce you to the course material through online videos and readings. You will also prepare with an online tutorial (Daily Work). In class, you will apply these concepts and solve problems in small groups and complete short quizzes (Daily Work). MLAs:

Video lectures will be assigned and textbook reading suggested as ‘Mastery Learning Assignments’ (MLAs) prior to each class. The content of these assignments is required— it will appear on quizzes and exams. Materials presented in MLAs may not be covered

explicitly in class lectures. Daily Work:

You will receive an overall ‘Daily Work’ score (15% of your grade) which will include daily quizzes, in-class problem solving, Mastering Chemistry tutorials and self-tests.

Quizzes:

At the beginning of each class period, you will be given a short and simple clicker quiz based on the material covered in the MLA. No make-ups will be given.

I n-Class P roblem Solving:

During each class, you will apply the concepts from the preceding MLA by solving problems with your assigned small group. You may use your notes and textbook to work these problems. You will be assessed through clicker questions.

M C Tutorials:

Online tutorials will be assigned through Mastering Chemistry prior to each class. They will always be due at 11:59 pm on the day before class. Each tutorial will contain hints that will explain the relevant problem-solving process. Six submissions are allowed for each tutorial question.

M C Self Tests:

Online self tests will be assigned through Mastering Chemistry for each chapter prior to each exam. Self tests will be due at 11:59 pm on Sunday of each exam week. These problems are much like end-of-chapter problems from the textbook; they have no hints. You will receive three submissions per question.

MC Policies:

No late work will be accepted in Mastering Chemistry for any reason. The MC clock will be used to determine the submission date/time. You may use your book or other resources when solving MC assignments, but each assignment is to be worked independently. Any collaboration or discussion is a violation of the honor code.

Practice Problems:

Recommended problems from the textbook will be assigned but not graded. Students are encouraged to work together on these problems.

Your Daily Work % will be calculated as a % of 200 Daily Work Points. Max possible Daily Work % is 100. Item Min. pts. Ea.

Chem 101 Evaluation Exams:

There will be three midterm exams held in-class plus a comprehensive final exam. No make-up exams will be given. Early exams may be arranged for students with legitimate reasons, at the discretion of the instructor. Early exams must be arranged at least two weeks in advance. Please bring your ONE card to each exam—failure to do so may result in a zero in that exam. If you request a regrade for an exam, the entire exam, not just individual questions, will be regarded.

Grading:

If you take all 3 exams, you will be graded on whichever option (A or B, below) give you the highest overall score. If you miss a single hour exam, you will automatically be graded with Option B.

Your final grade will be based on whichever option below gives you the HIGHEST overall score. If you miss an exam, you will automatically be graded with Option B. Item Option A: Option A: Option B: Option B: Points Possible % Breakdown Points Possible % Breakdown Daily Work Daily Work % 15% Daily Work % 15% score is scaled to score is scaled to 75 points 57 points Midterms 300 60% (3 scores: 200 52% (best 2 20% each) scores: 26% each) Final Exam 125 25% 125 33% Total 500 100% 382 100%

Academic integrity is at the heart of Carolina and we are all responsible for upholding the ideal of honor and integrity. Your enrollment in this course is a sign of your personal commitment to your advancement as a scientist; as such, adherence to the Carolina Honor Code is absolutely essential. I take the Honor Code seriously, and so should you. Since all graded work (Mastering Chemistry assignments, quizzes, exams) will be used in the determination of academic progress, no collaboration is permitted. This means you must complete all Mastering Chemistry assignments independently. Collaboration and discussion is a violation of the honor code.

Chem 101 Keys to Success:

The following tips will help you succeed in Chemistry  





 





Review the fundamentals. Sharpen your math skills! Stay Organized. A three-ring binder will be a very helpful tool in this class. You will receive notes and exercises in many different forms (your text, online videos, lecture notes, in-class activities, etc.). A binder is a great way to keep these many different forms of learning materials collected and organized. Come to class prepared. Complete all the Mastery Learning Assignments before coming to class. Complete all the graded mastering Chemistry homework problems by their deadlines. Come to class ready to engage in group discussions and complete in-class activities. Do the recommended practice problems. At a minimum, complete all the ‘red’ problems in your text. You have access to the solutions to these in the Student Solutions Guide. Solutions to the ‘black’ problems can be viewed in the Resource Center (Kenan 143). Only check your answers after you have completed a large batch of questions. A good study session feels like a hard workout; expect to be tired afterwards. Attend Q&A sessions. We will always have something interesting to do/learn. Bring your questions and be prepared to listen to the questions of other students. Be a good class citizen. Smile at you classmates and introduce yourself to htem. Ask someone in the class how their day is going. Switch off all electronic devices other than your clicker (computers, cell phones, tablets, etc.) while in class. Form a study group. Working with a study group outside of class will help you learn the material deeply. Your in-class working group is a great place to form these connections. Exchange contact information and follow up –

call/text/email/tweet/facebook others and ask if they want to study together. Use electronic resources. Mastering Chemistry offers a ‘study area’ with a host of practice multiple choice problems. These are a great way to prepare for in-class multiple choice assessments. Google can provide a wealth of extra practice problems



once you have exhausted those in your textbook. Get extra help if you need it. And get help as soon as possible! There are three venues for free tutoring. • Resource Center in Kenan 143. Hours are Monday–Thursday 2–8 pm. • Peer Tutoring Program in Dey Hall. Upperclassman offer one-on-one tutoring. Times and days TBA. • The Learning Center also coordinates free tutoring by appointment. http://learningcenter.unc.edu/services/Math%and%Science/tutoring-for-mathand-sciences
