All course activities related to the lecture material are reached through the course Canvas site. Zoom links are directly given on Canvas. Chem 2070, General Chemistry I, gives an introduction to the theory of the atoms and molecules. Topics introduced include stoichiometry, atomic theory, chemical bonding, chemical reactions, gases, and intermolecular forces. Chem 2070 is a lecture- and laboratory-based course consisting of two 50-minute lectures and one laboratory per week. In addition, pre-lecture, post-lecture, and exam prep (flipped class and peer-led) have been set-up to help students optimize their weekly chemistry study time.

Lecture Course access All lectures are given synchronously through Zoom links on the course Canvas site. Laboratory Sections All Chem 2070 students need to be enrolled in one laboratory section! Enrollment is done through Student Center. For further information see: Chem 2070 Laboratory Course Syllabus. Examinations All 2020 Chem 2070 examinations will be proctored and on-line (through Zoom). Exams have been set up with both Academic Integrity as well as internet and time accessibility in mind. While exams are all open notes and open internet, students may not share any exam content, directly or indirectly, during exam session times. Only exams downloaded and uploaded during the given exam session times will be scored. All communication with others is forbidden during the exam. Students will take the exams in proctored Zoom breakout rooms in as isolated a physical setting as possible. TA proctors can (and will) request 360o views of the physical site where the student is taking the exam. At the beginning of any exam session, students will be given different versions of the exam, with different students receiving different versions. The version a given student takes will be at random. Only students taking a given exam will have access to that exam during the exam times themselves. Each Chem 2070 exam will be held at three different main times and one make-up time. While only students who did not submit one of the three main versions of a given exam will be allowed to attend the make-up session, all students who did not submit at least one of the three main versions of a given exam will be allowed to take the corresponding make-up exam. Students attending a given exam session, need not hand in their exam paper for scoring. Conversely, students, who wish, will be allowed to submit up to two of the non make-up versions of a given exam (In the case where two exam versions are submitted by the same student, they will be averaged in a statistically meaningful manner). Students who fail to turn in any version of a given exam will be marked absent. Students who are able to provide valid excuses will be given an Excused Absence, with no adverse effect on their course grade. Unexcused absences correspond to a zero on the given exam. (No excused absences will be granted for travel for any of the exams.) A small number of oral prelim exams will be given by the professor of the course. Students, with whom the professor requests an oral exam, will be chosen at random. If requested by the professor (request will be sent via e-mail and student netid), students will be given one week, 128 hours, to arrange and take the requested oral exam. Oral exams will be recorded. In the case where the oral exam result is highly divergent from a corresponding written exam result, a

second oral exam will be requested (this time with a 96-hour window). The two of the three exams with the scores closest to one another will then be averaged to determine the students’ ultimate exam score. Without a valid excuse, failure to take requested oral exams within the allotted time will result in a final zero score on the exam in question. Exam scores on different versions and different questions are treated as raw scores. Results from different exams are merged (to account for statistical variations between different exam versions) so as to produce ultimate individual student exam scores. Complete instructions on exam protocol are given on Canvas course site. FYI, completely different versions of the exam are given at each different exam times. Each exam version will have multiple exam sub-versions. Prelim I Version 1: Sunday 10/4 4:00 – 5:30 PM EST Version 2: Thursday 10/8 5:30 – 7:00 PM EST Version 3: Friday 10/9 7:00 – 8:30 AM EST Make-up session: Monday 10/12 7:30-9:00 PM EST Prelim II Version 1: Sunday 11/8 7:30 – 9:00 PM EST Version 2: Friday 11/13 7:00 – 8:30 AM EST Make-up session: Friday 11/13 3:00-4:30 PM EST Final Exam Pending notification from the Registrar’s Office One main version and one alternate session will be offered. Extended time exams are administered through the Undergraduate teaching office. Weekly Course activities Pre-lecture Canvas modules (33 2070 course points) Pre-lecture Canvas modules have been prepared for all but the first Chem 2070 lecture. Modules open 6:00 AM EST the day before the first of the lecture sections and submissions on Canvas close five minutes before the actual first lecture session itself. Modules are designed to help students maximally benefit from the lectures. Pre-lecture modules begin with a START HERE quiz. Students are then suggested to move to additional quizzes, best suited for individual student needs. Students should follow these suggestions! Students receive 1.80 2070 course points for ½ hour of college level Pre-lecture STEM work. (The algorithm used to determine points is based on the amount of time spent on the Canvas modules, the number of questions attempted, and the number of correct answers.) An additional extra 0.45 Chem 2070 course points per Pre-lecture will be awarded if the scoring algorithm

detects that a significant extra amount of work has been carried out. The maximum number of 2070 course points a student can earn through pre-lecture module work is capped at 33 points for the entire semester. The successful student will receive notifications from Canvas that such-and-such quiz has not been done. Under no circumstance, should the student give any credence to these Canvas notifications. The receiving of such messages is actually the hallmark of a student who has been able to streamline their study habits in the best possible way!

Post-lecture problems (33 2070 course points) Directly after a lecture, students are invited to solve problems related to the lecture. Three different options have been set up for carrying out this work. For each lecture, students should choose one of the three post-lecture options. Canvas will send notifications as to all Options work which the student has not completed. Notifications not relevant to the Option which a student has chosen for a particular lecture need to be ignored. The receiving of such messages is the hallmark of a student who has been able to streamline their study habits in the best possible way! Option 1. Typed lecture-note problems: On Canvas, each lecture is given a two-page typed summary containing all the important points of the lecture. Embedded in the typed lecture summary are questions which the student can work on either independently or with other students (if working with others, it is a matter of Academic Integrity, that the others should be named.) Canvas specifies, for Option 1, which of these questions should be worked on and turned in. For credit, work needs to uploaded by 7:00 PM the day after the last lecture section. 2.0 2070 course points are awarded for each Option 1 activity posted. In Option 1, full credit is given to work which represents 45 minutes of college level STEM practice. Answers to lecture note problems are posted in files roughly one week after student answers have been uploaded. Option 2. Office hour problems: Students may attend one of the three hour-long office hours given in the day following each lecture. For the first lecture in the week, the corresponding Office Hours are Tu 9:15–10:15 PM; We 1:25-2:25 PM; and We 4:40-5:40 PM, all EST. For the second lecture of the week, the corresponding Office Hours are Th 9:15–10:15 PM; Fr 1:25-2:25 PM; and Fr 4:40-5:40 PM, all EST. At the start of the Office Hour, attending students are given the Access Code to the Office Hour Problem Set, a set of problems written solely for students attending the given lecture’s office hours. Typically, students are then placed in Zoom breakout rooms with roughly three – five other students. Students work side-by-side solving the problems. A half-dozen TAs and I will

go from room to room monitoring student progress. When needed, the class as a whole will be brought together so that we can guide the class as a whole through difficult points. At the end of the hour, students, via Canvas, will upload their answers. Work which represents one full hour of college level STEM work receives 2.0 2070 course points. While students can not receive post-lecture course points for Option 1 and Option 2 work for the same given lecture, they can receive 2070 course points for Option 1 and Option 2 work corresponding to different lectures. Students are encouraged to vary between Option 1 and Option 2 work based on their personal study needs and strategies. Office hour answers are presented in office hours at the end of office hours. They are not posted on Canvas. Option 3. On-Ramp program. Students may need additional guidance beyond that offered by Options 1 or 2. A third, more time costly, option is therefore provided. In this third option, students, via Canvas, sign up for both of two 75-minute per week classes. (Sign-up for the program in the first two weeks of classes requires the taking of the On-Ramp placement test.) These weekly On-Ramp class are given first at Tu 5:00-6:15 PM; We 8:40-9:55 AM; & We 2:554:10 PM all EST, and second at Th 5:00-6:15 PM; Fr 8:40-9:55 AM; & Fr 2:55-4:10 PM all EST. Each On-Ramp class has 30 - 45 minutes of associated homework attached to it. Students may sign up for On-Ramp in the first two weeks of the course or in the one-week period directly following Prelim I. While students may enter the On-Ramp program only in the above specified times, they may leave the program at any time of their choosing. Students, without a valid excuse, failing to attend On-Ramp at least 75% of the time will be removed from the program. While On-Ramp students can attend any On-Ramp session in the week with available space (see TA in the On-Ramp Zoom session at least five minutes before the start of class for availability), students will only have a place reserved for them in the On-Ramp session, in which they are enrolled. As long as students attend any of the three On-Ramp classes given on a given day, students will be marked in good-standing for the given week and will receive 2070 course points. Students completing a given On-Ramp class, whether in their enrolled section or otherwise, as well as spending 30 - 45 minutes of college level STEM effort in solving the homework problems will receive 2.25 2070 course points allocated for a given On-Ramp class. (Students following the On-Ramp program in a given week can not receive, in this given week, course points either through Options 1 or 2.) A placement test is offered via Canvas, from before the course beginning through the course’s second week, to all students, who wish guidance as to whether to pursue the OnRamp program. In the first two weeks of the course, the Access Code to the On-Ramp Canvas sign-up will be sent (via e-mail) to students based on their On-Ramp placement test results. (Scores on this placement test have no bearing on Chem 2070 course points or grades.) In past years, students benefiting from the On-Ramp program have received A’s in Chem 2070. Joining On-Ramp is based on student needs, not outcomes.

Irrespective of whether Options 1, 2, or 3 are followed, students are capped at 33 2070 course points for all post-lecture work. Answer keys to On-Ramp homework will be directly share with the On-Ramp students by their TAs. Flipped class (34 2070 course points) All Chem 2070 students need to be enrolled in flipped class! Flipped-class is offered at 19 different weekly times from Saturday morning through Monday afternoon, EST (Sa 9:05-9:55 AM;Sa 10:10-11:00 AM; Sa 11:15-12:05 PM; Sa 12:20-1:10 PM; Sa 1:25-2:15 PM; Sa 2:303:20 PM; Su 7:30-8:20 PM; Su 8:35-9:25 PM; Su 9:40-10:30 PM; Mo 8:00-8:50 AM; Mo 9:059:55 AM; Mo 10:10-11:00 AM; Mo 11:15-12:05 AM; Mo 12:20-1:10 PM; Mo 1:25-2:15 PM; Mo 2:30-3:20 PM; Mo 3:35-4:25 PM; Mo 4:40-5:30 PM; and Mo 5:45-6:35 PM; all EST) Flipped class enrollment is carried out through a link given in the course Canvas site. Section changes are carried out by the student through this same course link. Flipped class is a weekly peer-led activity in which students make the transition from processing lecture material to solving exam-level problems. Students receive short (5 - 7 minute) presentations from their peer TAs and then solve specified problems for the remainder of the 50minute class. 4.5 2070 course points are awarded for each flipped class fully attended. While students can attend any flipped class session in the week with available space (see TA in the flipped class Zoom session at least five minutes before the start of class for availability), students can only receive 2070 course points for attending the flipped class they are currently enrolled in. (Instructions on receiving the 2070 course points are given directly during the individual flipped Zoom sessions.) Flipped class 2070 course points is capped at 34 course points. Flipped class answer keys are uploaded one week before the first relevant prelim version. Peer-led exam-prep All students should enroll in a peer-led section. Enrollment is via Canvas. Section changes are carried out by the student through this same course link. Among all student activities offered by the course, peer-led exam-prep leads, on the average, statistically, to the highest up-tick in exam scores. (Statistics over a number of years demonstrate a 2 notch up-tick in final course grade, e.g., a C to a B- or a B to an A-. In 2019, the grade enhancement appears even stronger.) Peer-led is a weekly 2 hr. class in which students, in pairs, solve assigned Chem 2070 exam level problems written by the professor of the course. Students are allowed to enter the peer-led program during the first two weeks of the semester and during the one week following Prelim I.

Peer-led classes are offered weekly at Sa 9:00-10:55 AM; Sa 11:15-1:10 PM; Sa 1:25-3:20 PM Su 7:30-9:25 PM; Mo 12:20-2:15 PM; and Mo 2:30-4:25 PM. Peer-led class enrollment is carried out through a link given in the course Canvas site. Section changes are carried out by the student through this same course link. As peer-led is only effective for students going to peer-led on a weekly basis, students (without a valid excuse) who fail to either attend peer-led for two weeks in a row or fail to attend at least 70% of all weekly peer-led classes, are removed from the program. While students can attend any peer-led session in the week with available space (see TA in the peer-led class Zoom session at least ten minutes before the start of class for availability), and receive credit for having attended that weeks’ peer-led class, students will only have a place reserved for them in the peerled session, in which they are enrolled. Peer led answer keys are uploaded one week before the first relevant prelim version.

Chemistry 1007 The Learning Strategies Center offers Chemistry 1007 (one credit hour, S/U) to help students further understand the concepts presented in the course with the goal of improving performance. Chemistry 1007 is taught by Dr. Brandon Bogusz and will contain asynchronous video modules with additional synchronous problem-solving sessions held on Thursdays and Fridays. To gain access to 1007 resources, students can visit the 1007 Canvas: https://canvas.cornell.edu/enroll/TABWA6. Chem 1007 closely tracks Chem 2070 material.
