3 COURSE OBJECTIVES Introduce the fundamental concepts of General Physics and some their applications. Show how basic physical principles can be applied to the world around us. Establish connections between theory and problems. The quizzes and exams, in addition to test student knowledge, also serve as guide for the instructor to further focus and improve the presentation of the material, both for this semester, as well as future ones. Access to MasteringPhysics: To register for mastering physics, ONLINE HOMEWORK The assigned Online Homework problem sets will be on MasteringPhysics. The MasteringPhysics is linked through your physics 111 course on canvas. 1. Log in to Canvas and click PHYS 111 (Summer 2018) 2. Click on MasteringPhysics 3. Select MasteringPhysics Course Home and follow the instructions on the screen. If you have not registered for a Pearson course before, you will need to choose a login name; otherwise, you may use your current Mastering/Pearson login name. You can also buy the 7 th edition access code through the MasteringPhysics link From within Canvas course page. Note : If it asks for a course ID, you might not be logging in through Canvas. Do not go directly to the Pearson site. To access online homework, log in through course Canvas page PHYS 111 (Summer 2018) RECITATIONS Recitation are on Tuesday through Friday. Each recitation is 60 minutes long. In recitation, there will be hands on problem solving using preassigned problems or review of the online homework after its due date. Quizzes: At the end of every Wednesday and Friday recitation (Friday only in first week and Wednesday only last week), a 15-minute quiz will be given. Quizzes will be graded by the recitation TA and handed back to the students in the next recitation. Missed quiz: If you miss a quiz for a university approved excuse (e.g. being sick, being away due to an ISU related activity), you should bring some document to prove the reason of your absence to your TA. An Excused Grade will assigned to the missed quiz (i.e., at the end of the semester your score for the missed quiz will be the average of all the other quizzes.) 3

4 PLEASE NOTE: The total points associated with quizzes are as much as one of the mid-term exams. The path to a good final grade is paved by good quiz scores. LABS Information about labs (policies, grading, schedules) is posted in a separate Canvas page called PHYS 111 LABS (Summer 2018). Access this page as soon as possible to: a. Read the Laboratory Information and Policies; b. Take the Laboratory Policies Quiz (you need a perfect score on this quiz); and c. Figure out when your lab section meets for the first time. In particular, make sure you understand the make-up lab policies. If you have problems accessing the lab Canvas page, please contact the lab supervisor, Paula Herrera (siklody@iastate.edu). Completing all the labs and the corresponding prelabs is required. Failure to do so will result in an F for the entire course, independently of your performance in other components of the course. The final exam will contain four questions about the labs. Lab waivers: If you have completed the laboratory part of the course successfully during a previous semester at ISU, you may request a lab waiver during the first week of classes. This is done through Canvas. If this waiver is granted, your old lab grade will be used. You still have to answer the lab questions on the exams. The importance of the recitation and laboratory classes cannot be over-emphasized. You will not understand the material in this course if you cannot apply it to the solution of the assigned problems. The laboratory is essential to your efforts to understand the experimental foundations of physics as well as of scientific instrumentation. Questions based on recitation and laboratory classes will appear on the mid-semester exams as well as on the final exam. 4

5 EXAMS Mid - semester exams Midterm exams will be on Mondays during lecture hour. Note the exam dates: Monday, June 25, 2018 Monday, July 09, 2018 Monday, July 23, :10pm 1:10pm 12:10pm 1:10pm 12:10pm 1:10pm and make no other plans for these times. Final Exam Friday, August 03, :00am 1:00pm. If you have a conflict with the scheduled time for any of the exams or any other reason why you cannot take it at the assigned time, you must notify Dr. Al-Saqer at least a before the assigned time so that an alternative arrangement may be found. Material to bring to the exam: - a number 2 pencil, - a scientific calculator. Graphing calculators are not necessary but may be used. Laptops, cellphones, tablets or any smart devices are not allowed. - your student ID card. Each exam will include the values of any physical constants you may need, a formula sheet and scratch paper. Exams will be multiple-choice. Make-up exam: A single, end-of-semester, make-up exam will be allowed only in exceptional circumstances, such as illness, family emergencies (not anniversaries, family vacations, etc.), or official university-sponsored activities. Students who know in advance that they will miss an exam as a result of one of these university-sponsored activities must explain the circumstances to the lecturer well before the exam and seek permission to take a make-up exam. After the fact, such permission will not be granted. Students who miss an exam because of illness or other unforeseen emergencies should send a message (by phone, voic , , or through a friend) to the lecturer or the course secretary before the start time of the exam in order to receive permission to take the make-up exam. This make-up exam will be held during the week before finals week and will be a comprehensive exam. Clearly only one exam can be made-up in this manner. 5

6 STUDENTS WITH SPECIAL NEEDS: If you have a documented disability and anticipate needing accommodations in this course (for lectures, recitations, labs, or exams), please request that a Disability Resources staff provide you with a SAAR form verifying your disability and specifying the accommodation you will need. After getting your SAAR form, make arrangements to meet with Dr. Al-Saqer as soon as you can. GRADING Total Points break down: Exam #1: 50 Initial scale for letter grades Exam #2: 50 Total Score Letter grade Exam # A- or better Final Exam: B- or better Online Homework: C- or better Recitation Quizzes: D- or better Recitation participation: 10 < 215 F Laboratory: 40 Unsatisfactor y Lab F Total: 400 The above point scale for letter grades for the course will not be raised, but may be lowered (but only slightly.) A failing course grade (F) will be given if: 1. any laboratory has not been satisfactorily completed, or 2. the student has engaged in any form of academic dishonesty. Homework scores: Homework is an investment the direct credit from homework is only 7.5% of the final score, but this is the most important learning tool in the course. Homework is your opportunity to make mistakes and learn from them. Then you will be able to answer the exam and quiz questions correctly, which carry 75% of the total points. Recitation and lab scores: The precise number of recitation/lab points you receive from your instructors during the semester will not necessarily be the same as the number that counts towards your final grade. Some instructors grade "hard" during the semester and some grade "easy". Thus, in the interest of fairness to all the students, scores for hand-graded material may be slightly adjusted at the end of the semester to compensate for these differences. This means you will not automatically get a higher grade because you have an easy grader, or a lower grade if you have a hard grader. Grade book: You should regularly check that all your scores are correctly entered in the online grade book on Canvas. It is your responsibility to bring any problems to the attention of your section instructor immediately. Exam scores: If you believe there has been an error in the grading of an exam or 6

7 STUDENT ASSISTANCE Students can receive assistance with the material of this course: Room 53 Physics will be the Physics 111 Help Room. The staffing schedule will be Instructor office hours. Discussion board on Canvas. HOW SHOULD I STUDY FOR THIS CLASS? It is to your advantage to work with other students to learn the material. This can often help you to do better on the exams and homework. We encourage you to work together and perhaps form a study group. You may meet in the Physics 111 help room, if you wish. Please see the academic honesty statement for guidelines about working on homework assignments in a group. Keep up with the class! In physics, the material often builds upon what was covered Read the indicated reading assignments before each lecture. The reading Solve problems! It is the single most important activity in a physics class. If you Be honest to yourself: if you solved a problem without really understanding why and don't forget to reflect on problems you solved correctly. Identify key points in strategy used, key concepts and math skills required. Revisit the same problem later on and realize the time needed to solve it compared to previous time. Check the solutions posted online. Be sure you understand all of the concepts as Complex problem solving requires order: Always work with a pencil and paper, and Learn from your mistakes: focusing on your mistakes is the most effective way of As needed, reread the chapter summaries in the textbook. Review the appropriate Solve extra questions and problems in the textbook (the odd numbered problems Join a study group. You will benefit both from other students insight and from how explaining a topic to another person tests and refines your understanding of it.... but be careful: being able to follow a problem solved by another person is not the same Use the as being help room. able to This solve is it the on your perfect own! time Group to work get one-on-one should always time be followed with an instructor. 7
