Course Details:  Chemistry 0190 is a one-semester course that introduces General, Organic, and Biological chemistry to students in health-related fields (nursing, respiratory care, emergency medicine, dental hygiene and medical technology). The goal is to present the chemical principles and their relationship to living things. While a previous background in chemistry is not necessary for this course, basic math skills are VERY important! The course covers a lot of material (general, organic and biochemistry) in a short period of time. We will not go into a lot of detail, but it is essential to stay on to p of the reading and coursework! There is no course prerequisite – only a willingness to learn and a desire to explore the applications of chemistry in every aspect of your daily life.. Back to Top

Course Description: The title of the text, General, Organic & Biological Chemistry, an Integrated Approach, is an accurate description of the course. The integrated approach juxtaposes chapters of related material. This arrangement illustrates how inorganic chemistry and organic chemistry are linked to the biochemistry and health sciences that are essential to your future careers. Thus each chapter is related to those that preceded it. You will notice that concepts are related to one another. In the first three chapters we will work with the building blocks of the course: measurement, atoms, elements and compounds. Chapter 4 introduces organic compounds; most of the chemistry in biological systems involves large organic molecules. From there we’ll examine chemical reactions – classifying reaction types and quantifying the products. Most biological systems are mixtures – liquid-liquid, liquid-solid and liquid-gas. Understanding the behavior of mixtures is important for disease diagnosis. The chapter on acids and bases and the two which follow illustrate the important role acids and bases play in the chemistry that goes on around us every day. These include simple molecules like vinegar and baking soda and also more complex molecules like fatty acids, antihistamines, peptides and hormones to name a few. We’ll finish up the term with the chapters on carbohydrates, lipids, proteins and nucleic acids.

WWW, BlackBoard and EmailThis course makes use of many resources on the Internet. Much of the course material will be available exclusively through BlackBoard, a web-based container for course material. You will find an expanded course outline and course documents (lecture notes as PowerPoint slides, homework assignments, links to other general chemistry web sites, etc.). It also has a chat room and on-line grade book. This link will get you to your CourseWeb portal.  Use your Pitt user id and password to access these pages … from any computer, anywhere! The Wiley-PLUS Web site provided by the publisher is a valuable tool. You can review material from the text including photos and art, take practice quizzes or review vocabulary with flash cards. We will use Wiley-PLUS for homework and review. You MUST register for Wiley-Plus for this class. Be sure to locate and bookmark the two URLs listed at the top of the page! You will receive instructions for using BlackBoard and Wiley-PLUS throughout the semester.

You will receive Email for this course through BlackBoard; this will go to your Pitt email account.  If you prefer to use another ISP for your email (or HotMail, or GMail) you will need to forward your Pitt account to that email address.

Making the most of your Textbook:  You paid a lot of money for that book and the ancillaries! You would like to feel like you are getting your money’s worth. Some ways to get the most out of it include reading the text, working the recommended end-of-chapter problems and using the end-of-chapter study guides. My former students (see "Advice from Former Students" in the Course Information section of BlackBoard) will tell you that you have to read the book and you have to work the problems!

Homework counts!  Chemistry involves solving problems (not just number problems) and this is an important part of understanding the concepts. Therefore, it is critical that you make a habit of working (homework) problems regularly. While there will be occasional homework assignments (given in class), you are expected to work the in-chapter and end-of-chapter problems as a part of your regular study process. You will find a list of recommended problems posted on the BlackBoard page for every chapter that we cover in class. Many of these problems are the kind that you are likely to find on the hour exams. You will find it in your best interest to work as many of the recommended problems as possible. You will find a list of recommended problems posted on the BlackBoard page for every chapter that we cover in class.

A word about numbers:  Numbers are an essential part of science. It is important to appreciate the meaning of a number. In this class you will learn about exponents and scientific notation, significant digits in measurement and calculations and estimating answers. These are all important skills!

A word about Vocabulary:  To understand science, you must understand the vocabulary. You might want to keep a section of your study notes where you record the words you do not know (or even the words in bold-face in the text). Write a definition and them a phrase that helps you keep the word in context. This will really help with the exam questions! Back to Top

Does Class Participation Help?  ABSOLUTELY!  Class participation will not directly affect your grade. However, it could likely have a profound impact on your understanding of the material. This will become self-evident as you read about my teaching style and the comments from former students. Furthermore, if your final grade falls in that gray area, your class participation may count in your favor. Class participation is a willingness to be actively involved: to answer questions, to offer solutions to exercises and problems, to volunteer a different explanation or point of view, to ask questions. No matter how large (or small) the class, it's always possible to participate ... even if you sit at the back of the room.

Keeping a journal – a new approach to reading your textbookPut away your yellow highlighter! Buy a 100-page composition notebook.  Divide the book into three sections - use roughly half the notebook for section one then divide the other half about equally.  You'll probably want to set aside a couple of pages at the very front for a table of contents.  Use one of the smaller sections to keep a vocabulary list; use the other smaller section for a list of equations.  As for the big section ... this is your Reading Journal.

  • First some suggestions on how to read a chemistry text book You probably already know that a chem text is not the same as a history text and you definitely can't read it like you would your favorite novel.  Before you begin to read a new chapter do the following:
  • Look at the chapter outline (in the table of contents) and also the chapter objectives. These will give you an idea of the major topics as well as the concepts you should understand and skills you shold master for each chapter.
  • Flip through the chapter page-by-page looking at the section labels (probably the same as the chapter outline), the figures and the figure legends (Stop to read the figure legends).
  • When you get to the end, briefly study the "Chapter Summary & Problems" noting in particular the Vocabulary and Learning Objectives for the chapter.  The Learning Objectives are summarized and key to therelevant sections, practice problems and end-of-chpater problems. This should help guide your as you are reading.
  • For your very first journal entry make a list of your personal goals for this class this semester. This is very subjective material and there is no "right or wrong" way to do this. It's for your own benefit -- it will help you meet your expectations.
  • Begin a new page in your Reading Journal -- make sure you have some label for the particular chapter.
  • A word of advice - This Reading Journal will be more beneficial if you write your own paragraph (in your own words summarizing what you thought was most important) than if you copy or paraphrase the section summaries found in the text. Make entries in your journal as you go. Don't wait till the neight before the test. (Former students will tell you it's a waste of time by that point).
  • Create a section in your Reading Journal where you keep a list of vocabulary words.
  • Set aside a few pages for a list of important formulas.
  • As your very last entry assess how well you met your goals -- the ones you wrote in your first entry. Did you accomplish what you set out to do? Do you feel ready to go on to the next course in the sequence? Again, this is very subjective; there is no right or wrong answer. It's about what you accomplished.
  • At the end of the term you should have 16 entries - one for each chapter, plus your goals and self-assessment.
  • I will collect them at each hour exam, skim them and assign points (5) for each entry!  The points count toward your homework grade.

    Students Often wonder About

    What I Expect of My Students:  I have high expectations - for my students and for myself. I expect you to attend class and participate in the discussion period. I expect you to read the assigned portions of the chapter (if it is listed in the lecture schedule then it is assigned) and work the recommended problems. I expect you to turn in the assigned homework problems. I expect you to participate in the group problem-solving sessions. I expect you to master the learning objectives so that you will be able to pass the quizzes, exams and --ultimately-- the course. Needless to say, each one of you is responsible for all of the work in this class and the work you turn in must be your own. The overal goal of this Chemistry course is.

    To learn Chemistry is to learn a combination of terms (vocabulary), facts and concepts, to apply operational skills and to develop the ability to ask the question "What if?" and postulate an answer (or a means whereby you could obtain the answer).

    My goal is that everyone will learn some chemistry and that you will all pass! Back to Top

    My Teaching Style:  If you talk to my former students, many will tell you that I have an unorthodox style. Others will tell you that I expect you to learn the material on your own. This is true. I am also there to help you every step of the way. I assume that you have the ability to read the text book, learn the definitions of terms and follow easy algorithms to solve the simpler problems and think about the questions posed. Therefore, if I were to paraphrase the text in my lectures, you would probably loose interest, tune out and (perhaps) stop coming. My role is to clarify difficult concepts, help you learn to synthesize the information you extracted from the text and give you the tools to ask the questions "what if ?" This is the difficult part of learning; however, I'll be there to coach you -- all the way. If by the end of the semester you find yourself saying "I learned how to teach myself", then I have accomplished my goal!  ... and so have you!

    Sometimes I will lecture in the traditional fashion. That is, I stand at the front of the room, my notes in hand, talking and writing lots things on the overhead while you sit at your seats attentively listening and writing down as much of what I write, and say, as you possibly can. This method works very well when I want to focus on content. You can be guaranteed that you will have lots of "good notes". But this method doesn't always work -- especially when we are discussing a particularly abstract concept or a principle that is difficult to grasp unless you can experience it in action. This method also doesn't do a very good job of helping you develop that ability to ask What if ?.

    Often I do demonstrations. I expect you to pay careful attention and take notes about what you observe. Sometimes I will provide you some questions in advance; sometimes I'll ask questions after it is all over. I want you to think about what is happening, why it is happening and how it relates to the assigned chapter material. I want you to gain an understanding of how we can use experimental results to draw conclusions and develop "rules". I will help the class summarize how the demonstration illustrated the principle. Since it's difficult to "take notes" during this kind of class, I will try to give you time to summarize --in your own words in your notebooks-- what you observed and what it means. Back to Top

    Sometimes I'll start class by asking a series of questions. To an outsider, these questions may seem totally unconnected and not at all related to a chemistry class. In fact, they are very much related. My objective is to encourage you to think about these presumably abstract chemical principles by relating them to familiar things in your everyday life. You'll find that I ask a lot of questions. Sometimes, I think that you really do understand and I want to give you a chance to explain it. Sometimes I ask questions, because I sense that you don't understand and I need to know where I lost you. And sometimes I ask really stupid or redundant questions -- just to keep you on your toes. There is an important rule to this: There is no such thing as a wrong answer. Your answer may not be what I had in mind, or it may not be correct. However, more can be learned from figuring out the right answer. Knowing why an answer is not correct is often much more valuable than knowing the correct answer! And speaking of right and wrong, I make mistakes. Sometimes they are honest mistakes; sometimes they are intentional. I appreciate it when you catch my honest mistakes. I expect you to catch the intentional ones!

    Now, this back and forth dialogue can seem intimidating -- especially in such a large class or if I happen to call on you and you haven't a clue about what I want. I don't want you to feel like I'm putting you on the spot. So, if this happens to you, turn the people sitting around you. Ask them for ideas! They are allowed to help you formulate an answer.

    Chemistry is very visual -- and three-dimensional. Yet your text book is only two dimensional; a lot of times it uses chemical formulas that don't tell us a whole lot about the shape of the molecule. It's important to develop the skill to visualize the complete 3-D picture of a molecule from some cryptic formula. This skill comes with time, but I want to help you develop this skill. Consequently, I use lots of different ways to express chemical species. Sometimes I use the cryptic formula, sometimes I draw part of the shape of the molecule; sometimes I draw the molecule to make it look 3-D (there is a special convention and I'll teach it to you). I use molecular models (tinker toys) and computer software that generates molecules. I think that it is much easier to understand chemical reactions if we can visualize molecules moving in space. I realize that some people think in words and others think in pictures. I think in pictures. Sometimes I forget that not everyone thinks this way. So ... if you find yourself having an extremely difficult time visualizing something, stop me. We'll try to think of a different approach. Maybe one of your fellow classmates might have an approach that works better. Back to Top

    Another approach I use is to break the class up into small groups to work problems --sometimes everyone will have the same problem and sometimes each group will have a different problem. We'll do a lot of collaborative work this term. Cooperation is vital to learning effectively in a group environment.

    There's also email. It is not a substitute for coming to class; it is a supplement. You can use it in place of office hours. Send me a question, I'll send you an answer. Sometimes, I'll send your question (anonymously) and the answer to the rest of the class. I'll send you lists of problems in the text and other study problems. You can send email to the whole class through BlackBoard. Sometimes, I'll accept homework by email or through BlackBoard.

    How to prepare for class:  You must be asking yourself, "How do I prepare for this class?" Ideally you always want to be prepared. Given what you've read so far, it could be very uncomfortable if you weren't prepared. Admittedly this isn't always possible. A good rule of thumb is:

    "Two hours of studying for every hour spent in class."

    The Table of Contents, with the detailed headings for each section of the chapter, serves as an outline. At the beginning of each chapter you will see a list of learning objectives for that chapter. As you finish each section review the learning objectives and check the ones you have mastered so far. As you read each chapter, work through the Sample Problems and the Practice Problems. There are several different kinds of problems at the end of each chapter. First you will find problems keyed to each section. These are all designed to reinforce the concepts and skills presented in each section so it’s best to work them right after you finish reading the section. There are problems associated with the Health Links and Biochemistry Links. Work these also! The Thinking it Through problems ask you to push a little further with one or more of the concepts presented in the chapter. These are an excellent way of applying the course material to your daily lives! You’ll find a summary of the key terms and learning objectives at the end of each chapter. It’s a good idea to look over these study guides before you begin to read the chapter; they can serve as a road map pointing out the important landmarks along the way. Remember to read the Health Links and Biochemistry Links in each chapter; they reinforce the connections between chemistry and the health sciences and living things. See above about homework and journal.

    So, how about those "What if?" questions  ... no doubt you're curious. I'm counting on your curiosity to get you started. As we reach the end of a unit (just before an exam), it's a good idea to put together an outline – without looking in the book. Try your own organization method. Ask yourself how the concepts are related and how they are different. Draw lines (or arrows) between the related concepts. Annotate the arrows with brief explanations of how the two connected concepts relate. Put yourself in my spot and try to think of a good exam question that addresses that relationship. If you think you have a good question, send it to me; we'll discuss it in class.

    A Few Matters of Policy

    Academic Integrity:  Honesty and integrity are qualities we respect in ourselves and others. Therefore, you are expected to be fully aware of your responsibility to maintain a high quality of integrity in all of your work. Furthermore, you are expected to have read and understood the University Guidelines for Academic Integrity.

    The following should help to define the term cheating. 1) Sharing information on a problem set such that two or more answers are identical; 2) using unauthorized materials during a test or exam; 3) passing off as your own the ideas, words or products from some other source (better known as plagiarism). Cheating of any form will not be tolerated!

    If you are suspected of cheating, you will be allowed due process as established by the Academic Integrity Guidelines. In the event that the accusation is found to be true, a first offense will result in a grade of zero on that assignment (Homework, Quiz or Exam). Verification of a second offense, will result in a failing grade for the entire course. In either case, the V.P. for Academic Affairs, your advisor and the Disciplinary Board will be notified in writing.

    Back to Top

    AttendanceWhen you registered for this class you made a commitment to attempt all of the work that may be assigned. Attendance is not mandatory. However you will find that punctual and regular attendance is vital in order to carry out this commitment. Moreover, cutting class -- for whatever reason -- shows a lack of respect for your fellow class-mates and the professor.

    You are expected to attend and participate in the lecture and discussion period, read all of the assigned chapters, turn in homework problems and, of course, pass the quizzes, tests and final exam. You are responsible for all work assigned in this course. Furthermore it is your responsibility to obtain materials or instructions that were given in a class that you missed. These can be obtained from the instructor or a fellow class-mate.

    An excused absence is one where you, the student, have obtained prior permission from the instructor, or have a doctor's certificate in case of illness. In order to become eligible for an excused absence from an examination, you, the student, must communicate the reason for your absence to the instructor prior to the examination, if possible.

    Resources -- the Academic Success Center (ASC): Located in G-16 Owen Library, the ASC provides a variety of services including peer tutoring, supplemental instruction drop-in math assistance, drop-in writing consultations, academic advising for undeclared students, and accommodations for students with disabilities.  The ASC also provides resources and instruction on a variety of academic success issues and study strategies such as time management, reading textbooks, and test-taking.  In addition , the ASC has a small computer lab open to students.  Services are available to current Pitt-Johnstown students are free of charge.

    Back to Top

    Special Accommodations: If you have a disability for which you are or may be requesting an accommodation, you are encouraged to contact both your instructor and the Office of Health & Counseling Services (OHCS), G-10 Student Union, 814-269-7119 as early as possible in the term. OHCS will verify your disability and determine reasonable accommodations for this course.  

    Withdrawing from Class:   There are several dates to keep in mind regarding dropping a class from your schedule. The first is September 6, 2013, the end of the Add/Drop period. The next important date is October 25, 2013; that is the last date when you can withdraw from an individual class with a grade of W on your transcript. If you are not performing as well as you would like, you may consider dropping the class no later than this date. After that date, you must obtain a “Late Withdrawal” form from the Office of Academic Affairs to receive permission. Permission for “Late Withdrawal” is allowed only under extreme circumstances outside of a student’s control.

    Cell Phones & Other Electronic Devices: Modern electronic devices are great tools! However, they can distract us from the task at hand – i.e. paying attention in class. Please put your cell phone in silent mode and set it out of site when you are in class. If you want to go “paperless” and use a tablet of iPad or web book that’s fine. BUT – it’s FOR CLASS – not Face Book, not checking email, not ordering on line not …. It’s for class! Anything else is disrespectful. Your cell phone is not a calculator.

    Grading -- Exams, Quizzes & Homework:  There will be three one-hour exams and a comprehensive final. In addition, there will be several quizzes (in class and on line), homework sets and in-class problems worth a total of 100 points. The in-class exercises and problems assigned from the text will be checked for completeness, assigned a numerical score and returned. The total number of points earned for these short assignments and quizzes will be normalized to 10 and added to the final numerical score.

    All exams will be given on the scheduled date -- unless otherwise noted. Homework, when assigned, will be due the next class period. There will be no make-up quizzes; missed homework will be handled on an individual basis. All students must take exams (hour and final) at the scheduled times. Make-up exams will be allowed only in cases of documented illness or unavoidable absences (see above), and will be handled on an individual basis. Failure to abide by these rules will result in a grade of zero. 

    Back to Top

    The total number of points collected by a student will be divided by the total possible points (550) to compute a percentage. Letter grades, based on the percentage, will be determined according to an absolute ten-point scale. The +/- system is used for grades from A to C; as the instructor, I reserve the option of deciding the cut-off for + and - grades. There is no curve!
