Attendance is required. Blinn College believes that class attendance is essential for student success. Yes, I will take roll. Therefore, students are expected to report promptly and regularly to all their classes. There are four types of excused absence officially recognized by Blinn: (1) Observance of religious holy days. The student should notify his/her instructor no later than the 15th day of the semester concerning the specific date(s) that the student will be absent; (2) Representing Blinn College at an official institutional function, (3) official involvement in a high school activity for “dual credit” students, and (4) required military service will also be considered an excused absence. Other absences may be considered excusable at the instructor’s discretion with verifiable documentation. A severe personal problem, such as an illness or a death in the family may, with adequate documentation, warrant special academic consideration during the ongoing term for making up certain work or turning in certain materials late. However, the difficult situation is not in itself an excuse for failure to meet the course requirements. If a situation arises, it is the student’s responsibility to inform the instructor immediately of the situation and the associated circumstances. Make-up work may not be given for unexcused absences. If a student has a week’s worth of absences (two absences) during the semester, he/she will be sent an email by the College requiring the student to contact his/her instructor and schedule a conference immediately to discuss his/her attendance issues. If the student subsequently accumulates two weeks’ worth ( 3 absences for the summer terms) of absences, he/she will be administratively withdrawn from class. Remember, you must attend all labs; any absence in the lab counts as one day absence, as well.
There has been much discussion about the flu lately. If you think that you have the flu, please notify me, and don’t come to class. However, you need to inform me via email as soon as possible that you are about to miss, or have missed a class.
Homework is a requirement. There will be 4 assignments due during this semester, each worth 25 points, for a total 100 points. This will be worth 10% of your grade. The Homework collection and grading will be handled by the Mastering Chemistry system. A code must be purchased in order to access this system. Further instructions are given at the website http://masteringchemistry.com. Homework will be based on the following criteria: (1) Homework is turned in on time, (2) The assignment is complete, and (3) The answers are correct.
Exams are a requirement. There will be 4 Lecture exams given on the days indicated in the course schedule. I will give a fifth optional comprehensive Exam, thus giving you a total of 5 Exams. I will count your top 4 Exam grades. Each exam will be worth 100 points. These exams may have a combination of multiple-choice questions that will be machine-graded and non-multiple-choice questions that will be hand-graded. The Final Exam is comprehensive, all multiple –choice and worth 20% of the grade. Please note:
All exams are closed-book exams. No notes may be used on exams. All necessary information will be supplied to the student. Should you miss an exam, you will be allowed to make it up, assuming that you have a valid excuse. However, all make-up exams will be work-out problems only. As well, on all exams, including the final, there will be special rules in order to insure fairness: Please use the restroom before the exam. If you must leave the room for some reason, you must turn in your exam, and you will not be allowed to come back to the room. Thus, restroom breaks are not allowed on an exam or quiz. When taking a quiz or exam, you must place all personal belongings off your desk. You cannot use your cell phone during your exam.
Bonus Quizzes are a requirement (But they are a bonus!). Several opportunities will be given during the course of the semester to obtain quiz credit. You will have at least 8 scheduled quizzes, each worth 20 pts. I will take the five highest quiz scores as your quiz grade. As well, the quiz credit can take other forms, including small out-of-class projects. Some of these quizzes might be individual, and some will be group efforts. As stated above, there will be a minimum of 8 quizzes during the course of the semester, of which your best 5 will be counted. Remember, these quizzes are Bonus, meaning that the maximum 100 pts will be added to your final grade tally (see Grading Criteria). You will receive a key to each quiz after you have taken the quiz. If you miss a Lecture Quizzes for whatever the reason, you will not be able to make the quiz up (because these are bonus only).
Laboratory experiments are required. The laboratory portion of this course counts for 20% of this course. For each experiment you will receive a score between 0 and 25 (25 pts max.). The lab report must reflect information obtained by you while in the laboratory and recorded in your lab notebook. A Data Sheet from your lab notebook must be signed by me before you leave the lab (5 pts.). As well, you will need to sign a Lab Attendance Sheet. Lab Reports will not be accepted unless one of these has been completed for the experiment. Lab reports must be turned in individually (i.e., each student must turn in an assignment). The Prelab questions (10 pts) will be due prior to starting the experiment. There will be 8 experiments in this semester. (Remember, you need to attend all of the classes, including the labs.) Each Report with Prelab is worth 25 pts; therefore, the total will be 200 points. So, a typical lab report that you will turn in will have then following sections:
- Prelab (To be turned in before you start the experiment; worth 10 pts.)
- Data Sheet (To be signed by me, your instructor, before you leave the lab; you must put a copy of the data sheet in your lab report; worth 5 pts.)
- Postlab (This is the section of the lab report with your calculations and questions that you will answer after you perform the experiment; worth 10 pts.)
Students need to form groups of two in order to perform each lab. During the first class day, we will form the lab groups. If any groups of 3 are needed (due to an odd number of students in class), then I shall assign these. There should not be any groups of 4; if people choose to form groups of 4, they will be assigned a grade of zero. You need to attend all the lab sessions, if you miss a lab for any reason, a grade of zero will be awarded. There will be eight (8) labs this semester. We may add a ninth lab, but that has yet to be determined. Please note, your total lab grade will be out of 250 points.
Please note, eating and drinking are not allowed in classrooms or laboratories. This is especially true in the laboratories. You need to put away or throw away any food/drink before you enter the lecture room/laboratory.
Participation Grade. Blinn has now has added a participation grade to its core classes. Accordingly, this grade will be comprised of daily quizzes. These quizzes will be comprised of work problems, or they may be simple questions. In your schedule I have scheduled 7 of these quizzes, called lecture quizzes. Three more will be pop quizzes. The sum total of these quizzes will be 50 points, or 5 points per quiz. The second part of the participation grade will be in the lab quizzes. There will be two lab quizzes based on the experiments that you have performed.
EXAM AND MAJOR ASSIGNMENT CALENDAR:
Please note, you will have 4 exams and 4 homework assignments during the course of the summer term. For the 4 exams, your exam dates are the same as the due dates for the homework assignment
Mon 6/10 EXAM I on Chapters 11/12 Assignment 1 due
Mon 6/17 EXAM II on Chapters 13/14/15 Assignment 2 due
Mon 6/24 EXAM III on Chapters 16/17 Assignment 3 due
Fri 6/28 EXAM IV Chapters 20/22/23 Assignment 4 due
CRITERIA FOR GRADING AND DETERMINING FINAL GRADE:
Grading Criteria/Final Course Grade:
Exams (4 total) 400 pts 40%
Homework 100 pts 10%
Lab Experiments 200 pts 20%
Final Exam 200 pts 20%
Participation Grade 100 pts 10%
Quizzes (max. 100 pts) Bonus
TOTAL 1100 pts out of 1000 points max
The range of each letter grade will be assigned at the end of the semester. Based on prior grade assignments, typical grade ranges are:
Total Course Points greater than or equal to 900 = A
Total Course Points greater than or equal to 800 but lower than 900 = B
Total Course Points greater than or equal to 700 but lower than 800 = C
Total Course Points greater than or equal to 600 but lower than 700 = D
Total Course Points less than 600 = F
It is impossible to tell if there will be a curve for this class; hence, we will look at the grades at the end of the semester to see if one were warranted.
Blinn College Policies
Members of the Blinn College community, which includes faculty, staff and students, are expected to act honestly and responsibly in all aspects of campus life. Blinn College holds all members accountable for their actions and words. Therefore, all members should commit themselves to behave in a manner that recognizes personal respect and demonstrates concern for the personal dignity, rights, and freedoms of every member of the College community, including respect for College property and the physical and intellectual property of others.
Civility Notification Statement. If a student is asked to leave the classroom because of uncivil behavior, the student may not return to that class until he or she arranges a conference with the instructor; it is the student’s responsibility to arrange for this conference.
This statement reflects step one in a possible four step process. The Incivility Protocol is detailed in the Blinn College Student Handbook.
The College District believes that class attendance is essential for student success; therefore, students are required to promptly and regularly attend all their classes. A record of attendance will be maintained from the first day of classes and/or the first day the student’s name appears on the roster through final examinations. If a student has one week’s worth of unexcused absences during the semester, he or she will be sent an e-mail by the College District requiring the student to contact his or her instructor and schedule a conference immediately to discuss his/her attendance issues. Should the student accumulate two weeks’ worth of unexcused absences, he or she will be administratively withdrawn from class.
There are four forms of excused absences recognized by the institution:
- observance of religious holy days—The student should notify his or her instructor(s) not later than the 15th day of the semester concerning the specific date(s) that the student will be absent for any religious holy day(s);
- representing the College District at an official institutional function;
- high school dual credit students representing the independent school district at an official institutional function; and
- military service.
Other absences may be considered excused at the discretion of the faculty member with appropriate documentation. A student enrolled in a developmental course is subject to College District-mandated attendance policies. Failure to attend developmental classes shall result in removal from the course as defined by the College District.
It is the student’s responsibility to officially drop a class he or she is no longer attending. To officially drop a class the student must obtain the class withdrawal form from Enrollment Services, complete the class withdrawal form, secure the required signatures, and return the completed form to Enrollment Services. The last day to drop with a Q is according to the Academic Calendar.
Blinn College does not tolerate cheating, plagiarism, or any other act of dishonesty with regard to the course in which you are enrolled. The following text defines the faculty member’s responsibility with regard to the scholastic integrity expectation for this and all courses at Blinn College.
It is the responsibility of faculty members to maintain scholastic integrity at the College District by refusing to tolerate any form of scholastic dishonesty. Adequate control of test materials, strict supervision during testing, and other preventive measures should be utilized, as necessary, to prevent cheating or plagiarism. If there is compelling evidence that a student is involved in cheating or plagiarism, the instructor should assume responsibility and address the infraction. Likewise, any student accused of scholastic dishonesty is entitled to due process as outlined in Blinn College Board Policy FLB (Local). The Scholastic Integrity Policy is located in the Blinn College Student Handbook. In a case of scholastic dishonesty, it is critical that written documentation be maintained at each level throughout the process.
Students with Disabilities
Final Grade Appeal
a. Attendance: The College District believes that class attendance is essential for student success; therefore, students are required to promptly and regularly attend all their classes. Each class meeting builds the foundation for subsequent class meetings. Without full participation and regular class attendance, students shall find themselves at a severe disadvantage for achieving success in college. Class participation shall constitute at least ten percent of the final course grade. It is the responsibility of each faculty member, in consultation with the division chair, to determine how participation is achieved in his or her class. Accordingly, I have adopted the participation grade policy stated above (section 11, participation grade). Faculty will require students to regularly attend class and will keep a record of attendance from the first day of class and/or the first day the student’s name appears on the roster through final examinations. If a student has one week’s worth of unexcused absences (1 class) during the semester, he/she will be sent an e-mail by the College requiring the student to contact his/her instructor and schedule a conference immediately to discuss his/her attendance issues. Should the student accumulate two week’s worth of unexcused absences (3 classes), he/she will be administratively withdrawn from class. If your class meets 3 times per week, then this number should be 6.
There are four forms of excused absence officially recognized by Blinn College: (1) observance of religious holy days: The student should notify his/her instructor(s) not later than the 15th day of the semester concerning the specific date(s) that the student will be absent for any religious holy day(s); (2) representing Blinn College at an official institutional function; (3) official involvement in a high school activity for “dual credit” students; and (4) military service. Other excuses will be considered and may be considered excusable at the instructor’s discretion, with documentation. Missing lecture or lab or both will count as one absence.
b. Dropping: If a student chooses to drop the course, it is that student’s responsibility to complete a drop order at the Office of Enrollment Services. Failure to do so could result in a grade of F in the course. The last day to drop the class with a “Q” is Friday, June 21, 2012.
c. Honor System: Blinn College does not tolerate cheating, plagiarism, or other acts of dishonesty. Definitions of these acts and procedures for dealing with them are described in "Scholastic Dishonesty" in the Blinn College Student Handbook, copies of which are available at the information desk in the administration building. All tests will be closed book and notes. All students will remove hats and sunglasses before tests. We are on a student honor system which we will emphasize the entire the semester. Plagiarized work will be automatically given a zero and may be reported for disciplinary action.
d. Electronic Device Policy: All the functions of all personal electronic devices designed for communication and/or entertainment (cell phones, pagers, beepers, iPods, and similar devices) must be turned off and kept out of sight in all Blinn College classrooms and associated laboratories. Any noncompliance with this policy will be addressed in accordance with the Blinn College civility policy (Administrative Policy).
e. Problem Resolution: If you have a complaint about your class, you should first request a conference with your instructor to try and resolve the problems or issues. If the problems or issues cannot be resolved at the instructor level, you should first request a conference with the Chemistry Department Head, Mr. Thom Jose, firstname.lastname@example.org . If your issue has not been resolved, you must then schedule an appointment with the Associate Division Chair, Dr. Lee Don Bienski, email@example.com . Finally, if your problem has not been resolved, you can then speak with the Division Chair, Mr. Dwight Bohlmeyer, Science 241, firstname.lastname@example.org . The Natural Sciences Division requires that you follow this chain of command; if you go see Mr. Bohlmeyer first, chances are that he will ask you to go see Mr. Jose or Dr. Bienski first.
f. Health Concerns: Eating and drinking are not allowed in classrooms or laboratories.
g. ADA Statement: Reasonable accommodations for students with documented learning or physical disabilities will be made upon presentation of a formal request by the student. An official request form is supplied and completed by the Office of Disability Services (ODS) located in the College Park Center Administration Building (Room A-135). The URL to the Office of Disability Services webpage is http://www.blinn.edu/disability.htm. Accommodation is not retroactive from the time of concluding agreement for accommodation.
If you need individual accommodations to meet course objectives because of a documented disability, please make an appointment with me to discuss your needs as soon as possible so that we can ensure your full participation in class and fair assessment of your work.
h. Blinn Handbook: The above requirements and policies are discussed more fully in the Blinn College Student Handbook which, by reference, is incorporated into this information. Blinn College Student Handbook is available online at http://www.blinn.edu/student%20handbook.pdf. Please obtain and read.
15. Other Information
Please note, the only work that you can make up due to any absence is your exams. You cannot make up any labs or quizzes. Also note that all lab reports are due two class periods after the lab experiment is performed. So, if you performed a lab on Monday, the lab report is due on Wednesday. No labs are due on the day of an Exam. These rules may be amended by your instructor as the term progresses.
Please note well: The information contained herein is meant to be the guide that accompanies the course. We may on occasion effect a change to the schedule or clarify a certain point or modify a point within a policy. As your instructor, I will notify you during the course of the summer term of any such changes. It is your responsibility as a student to keep up with any changes brought to your attention and, especially, to keep up with the work required of this course.
Also, for this summer session, I will not conduct recitation sections, since we have no time for these.
This course covers Chapters 11-17, 20, 22, and 23 in the textbook.
