Trinity Valley Comm College Chem 1412 Internet Class Fall 2010 Wm Travis Dungan Room A103A, phone number 903 729 0256 ext 251 (Palestine campus) Email address: tdungan@tvcc.edu Getting started: Welcome to our online course. To access the Blackboard website for this course go to the TVCC website and click on ecourses at the top of the page and log in. If you are a VCT student your login username is your last name then first initial and the last four digits of your social security number (ex: for student john doe his username would be doej1234). Your password is the same as the username except that the first letter is capitalized (Doej1234). Once you ve logged on you ll be asked to choose a new password. The new password must have at least 3 of 4 requirements. It must have some combination of 3(you re better off using all 4) of: capital letters, small letters, numbers and/or symbols. An example is P@ssw1rd. If you are a TVCC student you must activate your Cardinal ID before you can access the course. To do this go to the school home page and follow the link. You can also find out your Cardinal ID there if you don t yet know it. (It is the first part of your TVCC email address.) You must change your password to satisfy the same criteria as shown above for a VCT student. If you have problems logging in go to ecourseshelp@tvcc.edu for assistance. There is also a "live chat" link on the TVCC homepage. Someone on the other end will work with you live to resolve your difficulties. There will also be a Blackboard shell you ll find on your sign in page that will have lots of assistance. So check it out. Communicating during the class: The best method to contact me is through the Blackboard email system, then using my TVCC email address shown above, and finally a call to my office phone. I make every effort to return your questions within the time frame here: time sensitive questions: within 2 business days not time sensitive: within 4 business days. You will be helping yourself and others if you are active in the course. Send an email to me or a fellow student or group of students, post a discussion or answer one, or form study groups either in person or online. This will make the course more enjoyable, help you learn and help others learn also. You learn best from teaching others!
There are no points involved in discussion posts as some course may offer. But I encourage you to get active on them. This helps to address the biggest weakness that distance courses struggle to overcome: a sense of community and sharing. You'll learn more and enjoy more if you do get involved. Course Needs: You'll need to buy a scientific calculator. I prefer a TI-35(or similar) and not a TI-83(or similar) and not a statistical calculator. You'll also need the next two items as well. Periodic tables are furnished to you in the course website. Textbook:Chemistry, by Whitten, Davis, Peck and Stanley, 9th ed. The ISBN for the textbook is: 0-495-39163-8. You can also use this ISBN:978-0-495-39163-0. Effective Summer 2010 you can go online to visit the TVCC bookstore website located at: www.tvcc.bkstr.com to buy your textbooks. There is also a link to this website on the TVCC homepage. Labkit: This course uses the CK-2 lab kit from AT HOME LABS. In order to successfully perform the lab experiments required in the course you must purchase a lab kit from the supplier. Shipping time is usually 4-5 business days. It is very unlikely that you can purchase the lab kit from a TVCC bookstore. There is a lab manual which is required. You ll find it on the cd inside the lab kit. The supplier is: AT HOME LABS 3203 W. Hampden Ave. Sheridan, CO 80110 Phone: Denver Area: 303-679-6252 Toll-Free, Long-Distance: 866-206-0773 Fax: 270-738-0979 www.labpaq.com E-mail: info@labpaq.com Navigating around Blackboard: You should spend some time exploring the course website to get familiar with using it. A great place to start is the links at the top of the homepage (or on the left side). Start with the GOALS link!! Everything you need to do is listed there and is broken down into sections. Instructions for doing your work, when it s due and how to turn it in are explained in the GOALS link. All my lecture notes, all your assignments, all the information you need to do them is in GOALS. It literally runs the course! You should also become familiar with the discussion, announcements, calendar links as well as all the others. You'll find the assignments given and your grades submitted in the my grades link, as well as your grade average and your letter grade. My teaching philosophy: The old saying, "Catch someone a fish and they'll eat well tonight but teach someone to fish and they'll eat well for life" sums up my attitude towards teaching. Especially when it comes to answering questions, inquiries, favors, etc.
Ask me a question and you're much more likely to get a useful fact or return question that should get you a step or two closer to finding the answer yourself. I rarely answer a question with a yes or no or direct factual answer. After many years of teaching I've seen over and over that folks will appreciate the effort more when they work it out themselves. And I'm loath to deprive my students of that wonderful feeling. Some folks like this Socratic approach to teaching and learning. Others can become somewhat exasperated. In either case, I will help you get there but there's no substitute to climbing that hill yourself. You will enjoy the view from the top that much better! Course description: This course is a continuation of general chemistry I. It assumes that you have taken a chemistry class previously (either gen chem 1411 or chem 1405) and are reasonably proficient in math skills. You will become familiar with important terms and concepts such as aqueous(waterbased) reactions, oxidation/reduction, the gaseous state, gas laws, the kinetic-molecular theory, solutions and properties of solutions, reaction kinetics, reversible reactions and equilibria, ionic equilibria, especially of weak acids and bases, the ph and poh scales, solubilities, solubility product constants and other concepts as time allows. Course Outcomes: the student should be able to use and understand the elementary chemical principles listed above. You should expect to demonstrate the accomplishments in the class assignments given and in your work turned in. You will pass the course by making a satisfactory grade on all assignments, experiments and tests we have. Specific details about learning outcomes are found in the next section. Chapter Level Learning Outcomes: These are the learning outcomes that you are expected to demonstrate mastery of during the course. Ch 10 Aqueous Reactions Describe the 3 theories of acids and bases.

Safety while doing lab experiments: You are expected to prepare for lab assignments (experiments) in advance and be ready to perform satisfactorily before starting the experiment. This means reading over the experiment ahead of time, understanding what is required, recognizing the lab techniques needed and the safety risks involved. You are expected to work safely and productively and to follow all safety rules (see lab manual) at all times. You are to follow all safety rules at all times. Evaluation and grading: I expect to cover the second half of this textbook, specifically chapters 10, 11, 13, 14, 16, 17, 18 and 20. There will be 2 tests and a final exam, which will not be comprehensive. Tests 1 and 2 will cover 3 chapters, test 3 will be over chs 18 and 20. There will be a homework assignment for each chapter. You will find all of this in the course website. You will perform all 11 lab experiments shown in the lab manual on the labkit cd. Points given out for work assigned are shown below: Tests 3 @ 100 pts 300 Homework 8 @ 10 pts 80 Syllabus quiz 1 @ 10 pts 10 Lab reports 11 @ 10 pts 110 Total 500 pts( one lab report will count as extra credit) *One of these is a quiz on this syllabus! Letter grades are on the basis of 90-100% = A, 80-89% = B, etc. A = 500-441 pts B = 440-392 pts C = 391-343 pts D = 342-294 pts F = < 294 pts total I will start posting grade averages/ letter grades after the first test and at least once a week until the end of the course. Testing protocol: Tests will be administered online in a proctored environment at a college testing center. The tests are password protected so you cannot take them whenever and
wherever you want to. You can use these items while taking your tests: a scientific calculator, a periodic table and some scratch paper. Nothing else is permitted. All test questions will be randomly drawn from homework, exercises and practice question test banks. This is to encourage you to turn in your work and look over as many practice problems as possible to prepare for the tests. You will have 2 chances to take each test. You can take it and then immediately retake your test a second time. You cannot leave and return. Each attempt will have a 1 hr time limit. Since the test questions are randomly selected the second attempt will almost certainly be different questions than you saw on the first try. However, since only your highest grade will count you have nothing to lose and maybe something to gain by taking it over. It's expected that TVCC students will test at a TVCC testing center. VCT students can choose a convenient location from the list of VCT approved college testing centers in Texas. You must provide me with contact information in advance of your testing session. You will need to contact your chosen testing center ahead of time as well. Many of them require an appointment and may charge $25 or more to test you. If that isn t possible for some reason other arrangements may be worked out on an individual basis but all tests must be proctored. Each test has a deadline date and must be completed (and submitted) by the deadline. On the chance it is necessary I do allow students to make up a test they have missed. The makeup test will not be the same test as was missed. Only one makeup test may be given. All homework, lab reports and exercises, will be due as shown on the Blackboard calendar and on the course home page. The course is somewhat self paced in that all the assignments are available the first day of class. The assignments will show as being late but they are not late until the deadline on the calendar and in the assignment description (found in goals) has passed. If you miss the window Blackboard will not accept an assignment. Since the course is relatively self paced and you can work ahead if you desire I won t accept any late work. Conduct Policy: All activities related to this course are guided by the Policy of Rights, Conduct and Responsibilities section of the TVCC catalog. We need to be open to discussion and consider the viewpoints of everyone in a non-judgmental way at all times. Cheating on any assignment/test/lab experiment, etc, will not be tolerated. This includes plagiarism, using material from other students, visiting external websites during a proctored test and other improper actions as spelled out in the TVCC catalog. Consequences may include a ZERO on the assignment and/or an F in the course.
Drop Policy: It is your responsibility to drop if you so desire. However, I reserve the right to drop students who don t log in to the course within the first month of class or if you miss the first test without notifying me in advance. This does not mean I will drop someone but if it appears to me you can no longer pass the course I may drop you. It s my belief that a W is always better than an F. This syllabus(7/18/10) is the Official syllabus for the course and all other previous syllabi are invalid. Please understand that this handout is subject to change without advanced notice from me but that you will be advised of any changes.
