12B Grading and Assignments

Your CHM 12B Course Grade (lecture and lab) will be based on your mastery of the 16 Course Objectives.

A = demonstrate knowledge, comprehension, application, analysis, synthesis, and evaluation of concepts and principles

B = demonstrate knowledge, comprehension, application, and analysis of concepts and principles

C = demonstrate knowledge and comprehension of concepts and principles

Your mastery of each Course Objective will be evaluated with these Graded Assignments you will do each week:

  • Quiz (15-20 minutes) or Multi-Objective Test (30-45 minutes).
  • Lab Activity.
  • Alchemie Mechanisms Homework (most weeks).
  • You are expected to work/study/practice 15 hours per week in this class.

Your Chem 12B grade consists of 11 Quizzes, 4 Multi-Objective Questions, Biology/Industrial Reactions Application, 12 Alchemie Mechanisms homework, and 15 Lab assignments. Every student will have an Incomplete Grade in this course until every assignment has been completed. Your Course Grade will be determined at the end of the semester when you have completed all course assignments based on the following criteria:

Grade Quizzes 4 Multi-Objective Questions Bio/Ind Rxn Homework Lab
A Pass 10 of 11 Pass 3 of 4 Questions B (>80%) or higher ≥ 87.5% ≥ 87.5%
B Pass 9 of 11 Pass 2 of 4 Questions B- (>75%) or higher ≥ 75% ≥ 75%
C Pass 7 of 11 Complete ≥ 60%
D or F Pass less than 7

A ≥ 87.5%, B range (75-87.5%), B- = 75-79.9%, B = 80-84.9%, B+ = 85-87.4%, C = 60-74.9%

Example: A CHM 12B student passes 9 Quizzes, passes 1 Multi-Objective Question, 65% on Bio/Ind Rxn, 75% on Homework, and 80% on Lab earns an overall C grade.

11 Quizzes (weekly)

Each Quiz will evaluate ONE Course Objective and will be given every Thursday. You will have 30 minutes to complete the quiz. Make sure you are available to take the Quiz on Wednesday between 6 pm and midnight. You will be allowed to use your book and notes. Each Quiz will consist of 4 or 5 questions and will be graded Pass (Master)/Not Pass (Master). A Pass (Master) Grade (80% or higher) means you have mastered that Course Objective. If you do NOT Pass (Master) a quiz, i.e., do not master a Course Objective, you can retake Quizzes 1-3 on 2/15/23, Quizzes 4-6 on 3/15/23, Quizzes 7-8 on 4/12/23, and Quizzes 9-11 on 5/10/23.

Four (4) Multi-Objective Questions

Each Multi-Objective Question will evaluate several Course Objectives and will be given on Wednesday, 2/15/23, 3/15/23, 4/12/23, and 5/10/23 between 6 pm and midnight. You will have 30 minutes to complete the Question, like a quiz. Each Question consists of one question with up to five parts; the question will be Pass (Master)/Not Pass (Master). A Pass (Master) Grade is 80% or higher. Make sure you are available to take the Questions on these days and times. You will be allowed to use your book and notes.

We will use Gradescope for online Quizzes and Exams this semester. Go to Gradescope.com. Make sure you use your Hartnell e-mail address. See Gradescope Help for more information.

Biology Reaction or Industrial Reaction Application

You will work in a group of 2 to 4 to apply 2 or more Course Objectives (except Objective 16) to a biology reaction or industrial reaction. The number of group members = number of Course Objectives in your biology reaction or industrial reaction. Each person is responsible for one reaction. Your group should check each reaction.

Your Biology or Industrial Reaction must be reaction types we have covered in Chem 12B this semester.

For each reaction, identify the reaction type, structural features, and reactive sites, e.g., alpha carbon, describe the mechanism using curved arrows, and other concepts that are important in the reaction. Other concepts may include resonance structures and stability, formal charge, configuration of reactants and products.

Submit your group names, biology reaction or industrial reaction, and Course Objectives covered by 5/1/23.

Submit (by e-mail or share via Google Drive) your Bio or Industrial Reactions Application presentation slides to me by Wednesday, 5/17/23 at noon. I will post your slides on the Chem 12B web page.

Each group will evaluate 2 presentations by Friday, 5/19/23 at noon. You will submit your review of each group’s presentation on a Google form.

Extra Credit added to Bio/Ind Reaction grade: BACON (Biology And Chemistry Online Notes). These tutorials are biology reactions that are explained with organic chemistry. We will review some of these bio reactions in lecture. THESE BIO REACTIONS ARE POSSIBLE REACTIONS YOU AND YOUR GROUP CAN DO FOR YOUR BIOLOGY OR INDUSTRIAL REACTION FINAL EXAM PROJECT.

11 BACON tutorials @ maximum 10% of Bio/Ind Reaction. The cost is $6 to do these BACON tutorials (funds go to the developer at UCLA). Go to LearnBacon.com, click “Sign Up” to create an account. Follow the instructions and then register for Hartnell College – CHM 12B. When prompted, enter this PIN: HC12B$. Each tutorial has specific start and end dates during the semester. Take the Quiz at the end of each Tutorial. Your Quiz Score determines your Extra Credit.

NOTE: Do NOT miss Multi-Objective Questions, Quizzes, or the Bio/Industial Reaction Application. If you know you cannot take a Question or Quiz on the scheduled date and time, inform me as soon as possible before the Question or Quiz in writing and reschedule the exam. Missing a Question or Quiz without valid reasons will result in a not pass grade.

Homework

You have to put in the study time (2 hours of deliberate, active practice for every lecture hour) to do well in this class.

A Homework assignment will be posted on the Chem 12B Homework page after each lecture. Homework consists of textbook readings, videos, online practice problems (ungraded b/c answers are given), and GRADED assignments using the Alchemie Mechanisms app (you used this app in Chem 12A or $9.99 for full access). There will be 12 Alchemie Mechanisms homework assignments this semester. Late Alchemie Mechanisms Homework will NOT be accepted.

After you download the app onto your tablet or phone, click on “sign in” (upper right corner) to create an account. After you verify your e-mail, click on the gear icon (upper left corner) and use this course code: vhsnb9

NOTE: 1. You have to register to earn credit for doing each Mechanisms homework assignment.

  1. You will earn a homework grade for the Mechanisms exercises you do this semester.

Other Homework includes Retrieval and Deliberate Practice of course material. While reviewing course material, practice retrieving the information and develop your problem solving skills by doing the Quiz Practice Problems (with solutions) on the Chem 12B website, textbook problems, or both spaced over time. This will help your long term retention of these concepts.

Laboratory

In science, observations are made to discover, learn, and understand what’s going on in nature. In science courses, hands-on activities are the best way to make observations and learn science. As such, the laboratory is a very important part of this course. You may be asked questions related to these labs on lecture quizzes. In Chem 12B lab, experiments demonstrate and elucidate concepts discussed in lecture. You will synthesize, separate, isolate and characterize organic compounds using organic chemistry microscale lab techniques. You will also gain an awareness of organic substances. Although many organic substances pose safety concerns, e.g., flammability, toxicity, mutagenicity, carcinogenicity, the Organic Chemistry lab is a safe environment as long as you are aware of the nature of these substances and their proper use and handling. Guidelines for lab procedures and lab safety are described in the Chem 12B Lab Information and Grading page.

Science is a collaborative endeavor. Employers value employees who know how to work as a team. You will work in a group of 2 in lab. Make sure each team member contributes equally to each experiment. However, each student is responsible for doing each lab assignment individually. Expect to spend the entire lab period in lab.

Your Lab Grade consists of 15 Weekly Lab Activities and Lab Safety Factor.
