Course Synopsis

This course is the first half of the CHM 111112 sequence that explores introductory concepts in chemistry. This semester we cover topics that include atomic and molecular structure, chemical bonding, chemical reactivity, gas laws, and thermochemistry. My main goal with this course is to teach you how to think like a chemist by using both qualitative and quantitative evidence to explain and to predict reactivity. To accomplish this goal, you must learn methodologies that chemists use, such as ways of solving problems, nomenclature and terminology, descriptions of electronic structure and chemical bonding, calculations to generate quantitative information, as well as how experimental data are interpreted. Hence, this course satisfies Area 3 of the Liberal Studies requirement for General Education.

Prerequisites One year of high school chemistry is required, but at times you will also need to rely on some basic algebra and quantitative reasoning skills. Required Materials

Course Format

This course follows the Process Oriented Guided Inquiry Learning, or POGIL, model in which you spend the majority of class working with three to four other students as a learning team to complete activities designed to help you explore and discover concepts. The main purpose of the learning teams is to introduce you to the active, collaborative nature of learning, particularly at the collegiate level. (Up until the first exam, I allow you to form your own learning teams, and I encourage you to work with as many different classmates as possible. After the first exam, using scores, as well as your input, I assign groups.) Outside of class you reinforce what you discovered in class by reading sections from the text and by applying the concepts covered in the activity by working problems. Each class period is structured in the following manner. At the beginning, you take a short quiz on the assigned reading. After some brief announcements, you then work with your learning team on the activity

assigned for that class. All activities consist of a model or data followed by critical thinking questions. These activities must be completed without the aid of any additional sources. Your main goal during each class is to ensure you and other team members comprehend the content of the activity, not to complete the activity as quickly as possible. For each activity you serve in one of the following roles:    

Manager to assign roles to other members, to assure the team remains on task and members are participating, and to communicate with the instructor; Recorder to keep the “official” copy of the activity to be handed in for review and to report answers to questions during oral presentations. Technician to handle models or equipment, to perform calculations, and to inspect responses, especially with regards to significant figures; Analyst to monitor team dynamics and to complete the summary sheet at the end of class. (If your learning team only consists of three students, the same person serves as both Manager and Analyst.)

At various times during class teams report answers to certain critical thinking questions. At the end of an activity we have a brief discussion as a class to summarize the main points. If time allows at the end of class, your team may work the exercises and problems given at the end of the activities. Learning Objectives

Upon completion of the course it is expected that you will be able to: 1. Solve numerical problems, giving answers to the correct number of significant figures and with the correct units. 2. Recognize the basic components of an atom and demonstrate how atomic composition gives rise to the structure of the periodic table. 3. Explain the basis of the quantum numbers and describe the shapes of atomic orbitals and electron properties based on these values. 4. Compose electron configurations for atoms and ions, as well as infer physical and chemical properties with this information. 5. Construct ionic and molecular formulas, in addition to naming ions, ionic compounds, and molecular compounds. 6. Using Lewis, VSEPR, valence bond, and molecular orbital theories, describe bonding within and shapes of molecules and ions. 7. Write balanced chemical equations, as well as perform stoichiometric and thermochemical calculations using these balanced equations. 8. Predict changes in state based on ideal gas relationships.

Grades

Semester grades will be assigned using the following cutoff percentages: A A− B+ B B− C+ C C− D+ D D− Grade Cutoff % 93 90 87 83 80 77 73 70 67 63 60

Evaluation Criteria

Your course grade is determined based on a combination of team participation, reading quizzes, online homework, hourly exams, and the ACS First Term General Chemistry Exam as a final. The weighting of each of these components is as follows: Team Participation Reading Quizzes and Online Homework Hourly Exams ACS First Term General Chemistry Exam

5% 10% 60% 25%

Team At the end of the semester I award a score out of 25 points based on your level Participation of participation within your team. Although regular attendance for class is expected, just coming to class is not enough to earn these points—you have to continually participate in completing the activities. You are allowed up to three absences from class over the course of the semester before points are deducted from your team participation score. I do not differentiate between excused and unexcused absences in calculating your team participation points. Reading Quizzes

For each reading assignment you take a short quiz at the beginning of the subsequent class. These reading quizzes consist of two true or false questions, each worth 1 point, that are based on concepts and not calculations. (Hint: Pay attention to words in the text printed in bold.) There are a total of 35 reading quizzes to be given this semester.

Online Homework

Problems for you to complete in WebAssign are listed in the schedule at the end of this syllabus. I suggest that you work the problems soon after the class period in which the relevant activity is completed. These exercises are to help you better understand the material presented in the activity and are crucial to your doing well on the exams. Please take them seriously and realize that ultimately you are individually responsible for understanding the material. Moreover, I use your performance on the problems to gauge the amount of effort you are putting towards mastering the concepts. There are 72 problems total divided into 12 problem sets that are due by the start of class on the dates indicated. You are allowed up to the number of attempts specified on each problem before the due date. Prior to submitting answers for scoring, you have the option of either practicing the problems in WebAssign for no grade or working the corresponding problems in the textbook and checking your answers using the solutions manual on reserve in the Bishop Library. Note, however, that the problems in WebAssign are modified slightly to adapt to an online format. Numerical portions in particular are not consistent between the textbook and the online version of the problem. In addition, the random numbers generated for the practice version are not the same as those for the version being scored. After the due dates, problem sets remain available in WebAssign for practice up until the time of the final exam.

Exams

Three exams are given in class on the dates listed in this syllabus. These exams cover material up through the review session prior to the exam. Each exam is worth 100 points. If everyone on your learning team scores at least an 80%, all team members receive 3 bonus points. During the final exam period I administer the ACS First Semester General Chemistry standardized exam. This exam consists of 70 multiple choice questions. I calculate final exam grades using a mathematical function that transforms the national norm into a 75%, or C, on the semester grading scale.

Help Sessions

In addition to my office hours, two problem-working sessions are offered on a weekly basis. Times and locations of these help sessions are announced towards the beginning of the semester. These sessions are staffed by chemistry majors to provide step-by-step help on working the various types of problems you encounter in this course. If you need more direct one-on-one help, please stop by during my office hours or fill out a Peer Tutoring request.

Academic Honesty

Any student who submits plagiarized work will be subject to the penalties described in the Student Handbook and outlined in LVC’s “Academic Honesty Policy” (http://www.lvc.edu/catalog/acad-reg-procedures.aspx). This code asks each student to do his/her own work in his/her own words. A student shall neither hinder nor unfairly assist the efforts of other students to complete their work. All individual work that a student produces and submits as a course assignment must be the student's own. Cheating and plagiarism are acts of academic dishonesty. Cheating is an act that deceives or defrauds. It includes, but is not limited to, looking at another's exam or quiz, using unauthorized materials during an exam or quiz, colluding on assignments without the permission or knowledge of the instructor, and furnishing false information for the purpose of receiving special consideration, such as postponement of an exam, essay, quiz or deadline of an oral presentation. Plagiarism is the act of submitting as one's own the work (the words, ideas, images, or compositions) of another person or persons without accurate attribution. Plagiarism can manifest itself in various ways: it can arise from sloppy note-taking; it can emerge as the incomplete or incompetent citation of resources; it can take the form of the wholesale submission of other people's work as one's own, whether from an online, oral or printed source. Students who take part in violations such as cheating or plagiarism are subject to a meeting with the Associate Dean of Academic Affairs, who has the authority to take further action, up to and including expulsion from the College.

Electronic Devices

The only electronic device permitted to be used during class is a scientific calculator. Mobile phones should be put in silent mode and may be used during class only in the case of an emergency. Laptops, tablets, and smart pads must be turned off during class. Any student that uses an unauthorized electronic device risks having team participation points deducted. For exams, only scientific calculators may be used; no other electronic devices, such as graphing calculators, phones, tablets, smart pads, laptops, etc., are allowed during exams. Students who violate this policy will be subject to academic honesty discipline outlined above.

Course Evaluation

During one of the last several weeks of the course, you have an opportunity to evaluate different aspects of this course. The College utilizes a standardized course evaluation instrument called IDEA. The IDEA evaluation is administered through an on-line form that you are asked to complete in a timely manner outside of class. I have chosen the following objectives for evaluation using IDEA: 1. Gaining factual knowledge (terminology, classifications, methods, trends) 2. Learning fundamental principles, generalizations, or theories 3. Learning to apply course material (to improve thinking, problem solving, and decisions) 4. Acquiring skills in working with others as a member of a team

Disability Services

If you have a physical, medical, psychological, or learning disability that is going to impact your attendance or require accommodation, please let me know. In order to ensure that your learning needs are appropriately met, you will need to provide documentation of your disability or medical condition to the Director of Disability Services. The Office of Disability Services will then provide a letter of verification of disability that describes the accommodations needed for this class. Accommodations are not retroactive. This office is located in the Humanities Building, room 04, and the Director may be reached by phone at 717‒867‒6071.
