2 BRAZOSPORT COLLEGE SYLLABUS CHEM 1411-General Chemistry I II. COURSE EVALUATION Student Evaluation One hour exams are designed to measure the student's mastery of the course objectives. Homework assignments and short quizzes are designed to indicate whether or not the student is doing the assigned reading carefully. Laboratory exams, if any, are intended to measure the student's laboratory techniques, understanding of experiments done, and how the student can apply concepts covered in lecture to practical situations. The laboratory grade will be the average of the experiment grades and exam grades. The course grade will be determined from the following: Major exam average 40-65% Lab average 20-30% Final exam 15-25% Homework and/or pop quiz average 0-20% TOTAL 100% Each instructor will announce the exact percentages to be used at the beginning of the course. Provisions for Meeting the Special Needs of Students Any make-up work that the student desires may be permitted during the semester, or following the semester if an incomplete is given, but in any case, will be at the discretion of the instructor according to the circumstances of each individual situation. Provisions, as may be necessary, will be provided to accommodate any special needs students so that they will be at no disadvantage compared to the other students, as far as is possible, either in experiences provided or in evaluation. Anonymous student evaluation forms will be distributed at the end of the semester, and will not be read until after course grades have been turned in. Students are invited to submit course and/or instructor criticisms and suggestions throughout the semester. 2

3 Instructor Evaluation A. Students will be given an opportunity to evaluate their instructor and the course content. B. Instructor will review and evaluate in terms of withdrawal rate. C. Final grades given will be reviewed in an effort to determine if a pattern of high or low grades exists. Department Evaluation A. Faculty and the Division Chair will review students grade and withdrawal trends. B. Faculty and the Division Chair will review the Course, Competencies, and Perspectives Assessment 3

Learn basic terminology and the application of the mathematical skills required to interrelate numbers of atoms and molecules to mass and units of concentration. B. Become familiar with the structure of the atom and its corresponding placement on the periodic table, as evidenced by the ability to predict various properties such as size, ionization potential, electronegativity and electron affinity from the position of the element on the periodic table. C. Write the electronic configuration of an atom and explain an element s reactivity in terms of its electronic configuration. D. Be able to explain in writing both how and why various elements combine to form compounds. This should involve the interrelation of the fundamental concepts of bond theories covered in class into broader abstractions or principles. E. Identify and recognize the limitations and differences among competing scientific models of chemical systems; such as covalent bonding and hybridization versus molecular orbital theory, and the various acid-base theories. F. Gain a basic understanding of the behavior of elements and compounds in solutions and in chemical reactions. G. Be able to predict the behavior and properties of molecules and ions in the gaseous, liquid, and solid states given a set of physical conditions. H. Demonstrate knowledge of the physical and chemical properties of solutions of electrolytes and non-electrolytes. I. Gain a background in chemical principles sufficient for success in more advanced courses such as Chemistry 1412 or Chemistry J. Acquire basic laboratory skills and carry out quantitative procedures in a laboratory setting as specified in section III. 4

Published by McGraw Hill, CHEM 1411 Lab Manual, Brazosport College, Published by Cengage. Scientific Calculator Safety Goggles - must meet ANSI Z certification. Course Description: This course is a review and extension of basic principles of chemistry, together with a study of the elements and then" compounds, bonding theories, kinetic molecular theory, solutions and quantum chemistry. To pass the course, the student must successfully complete (grade of D or above) the laboratory portion of the course. Prerequisite: Grade of C or better hi high school chemistry, or grade of C in CHEM or approval of Division Chair. Expectation of Students Students will: Attend every class. Show up prepared (text, notebook, pen, assignments completed) and on time. Seek help at the first sign of learning difficulties. Fully participate in the class. Have contributed significantly to all assignments turned in for credit (no copying). Not cheat on any examination. Grades: Final Grades will be determined according to the following system: Hourly Exams 48% Homework / ChemSkillBuilder 12% Lab 20% Final Exam 20% 12

13 Note: a student must successfully complete the laboratory portion of the course (60 or above) to obtain any credit for the lecture section Chem Examinations The examinations will last approximately one hour and fifteen minutes during class, with the exception of the final, which will last two hours. The exact date of each quiz will be announced in class closer to the actual date. There will be no make-up exams. However, if the student anticipates a legitimate absence (as judged by the instructor) for an exam, arrangements can be made to take the exam. This must be done before the next scheduled class after the exam. A missed exam will be counted as a zero toward the final grade.. Homework Assignments: Homework assignments are based on the Online ChemSkill Builder. The average of your scores from ChemSkill Builder will count as 12% of your grade. ChemSkillBuilder has the advantage of giving the student immediate feedback concerning the correctness of the student's work. If a student answers incorrectly, the correct answer with an explanation is provided. There is no limit to the number of times a student can complete an exercise. If a student scores higher in a subsequent try the higher grade will be figured into the average. To receive any credit for the homework, it must be completed on or before the due date listed in the schedule. Instructions for student self-registration are as follows: Log on to. Click on "New Student Registration." 1. Enter your Student Login Number and create a user name. Click on "Submit" when finished. 2. Fill in all of the boxes. Click on the school drop-down menu and select "Brazosport College". Click on instructor drop-down menu and select "Lowery". Select CHEM1411 and Section 1 3. When registration is complete, you will be asked to log back in with your student login number and user name. 4. You are ready to begin ChemSkill Builder. Click on an assigned unit from the left-hand navigation bar and begin. Class Attendance Policy If you are unable to complete this course, you must withdraw by March 26. Withdrawal from a course is a formal procedure, which the student must initiate. If you stop attending class and do not withdraw, you will receive a performance grade, usually an "F". If you think you must withdraw from this course, please talk with me about it first. Being late for class and leaving class early (without permission) are extremely disruptive to the class. If it becomes habitual, the student will be asked to withdraw from the course. Academic Code of Conduct A student, who cheats on an exam or other assignment, will receive a zero for the exam or assignment. Repeat offenses will be discussed with the Dean of Student Services and will result in a failing grade for the course. While studying with fellow students is encouraged, any work turned hi for credit must be substantially the work of the student (no copying). Students are advised to read the Standards of Student Conduct in the Student Guide and Calendar for a complete description of college policies, rules and regulations hi this and other areas. 13

14 Class attendance and participation will be important to your success. Come to class prepared. This means that you should spend at least six hours per week outside of class studying and doing homework assignments. Space out your studies evenly. Your retention and understanding of the material will be enhanced if you follow these simple rules. Course Objectives; The course is designed to help the student: A.
