Course Expectations
Learning occurs by the active involvement of the student.Consequently there will be many different opportunities for active learning, such as cooperative problem-solving in lab. The student isexpected to come to class prepared to think and learn. The lecture period will be used to establish fundamental concepts. The lab periods will be used to practice the engineering skills of problem-solving and data acquisition and analysis.

During both lab and lecture time, you will be asked to participate in solving problems. Always bring your calculator to both lab andlecture. It also is helpful to bring your textbook along.

To get the most out of this class, you need to read the assigned sections in the textbook before coming to class, and most importantly to read the assigned Lab Notes before coming to lab sections. There will bequizzes in the lab sessions. It is advisable to review the Learning Objectives frequently to keep track of your own progress. Don't feel that you have to be failing the course to come see your instructor or TA; come to ask questions.

Study Suggestions for EE171 (and Upperdivision Engineering Courses)

1) Do the reading before each lecture, the readings are listed for each lecture in the schedule above.
2) Read with a pencil and paper and try to do all the examples before you read their solutions. This is very valuable.
3) Seriously engage with all the homework problems, try them all before you work with someone else. There is no substitute for doing lots of problems to learn this material.
4) Make a copy of your homeworks and check your result against the solutions. Go back and figure out what you didn't understand.
5) This class is challenging and moves rapidly, falling behind is fatal. The results from one week will be used the next.
6) You need to be able to figure out what you don't understand and then ask your fellow students, the TAs, or the instructor for help if you cannot figure it out on your own.
7) Take notes and review them before lecture.
8) You are encouraged to work in groups and discuss about the homework assignments. However, each has to write his/her own solution and fully understand them

Homework Assignments
Homeworks will be assigned and collected during class sessions,and will generally follow a weekly sequence. Solutions will be handedout (or posted at our web site) on the date of collection. Thus, latehomework will not be accepted or graded. Homework is graded in terms of it being complete, well organized, readable and showing evidence of thoughtful attention to the problem itself. Sloppy submissions will not be considered for grading.

Grading Method
The course will not be graded on a curve. It is possible for everyone to earn an "A" or for everyone to earn an "F". Yourfinal course grade does not depend in any way upon anyone else's performance. Thus it is to your benefit to find a group of people you can study with and to help each other learn.Getting 50% in the final is mandatory in order to pass the class.

Lecture Quizzes: Quizzes will be given that cover the material from the lectures reading assignments and homework from the previous assignments. Besure to look over your homework and solutions to make sure that you understand how to do all of the problems. Since your homework will not in general be returned prior to the quiz you may wish to make a copy of your assignments so that you can check them yourself against the solutions. Homework problems will definitely be on the quizzes and probably on midterms and finals. Quizzes will sometimes be given at the beginning of class so don't be late.

Laboratories
The lab sessions take place in BE 113.
Each lab report is to be submitted the following week, at the lab or section. For each day that the report is late, 5% will be subtracted from the grade.
Midterm and Final problems frequently seem to have come from problems related to the labs in the past. Be sure that you not only do the mechanics of the lab but that you also understand the circuits, principles and topics involved.

• Twice during the quarter your engineering notebooks will be checked off by the TA. The collection times will be random, as the idea is to update your notes as you do the experiments. The lab books are your personal notes, so they don't need to be neat, but you need to demonstrate acceptable lab technique. See the section on Engineering Notes /Lab books in EE171L syllabus.
• There will be an oral final exam for the lab.

Lab Quizzes: At the start of each new lab there will be a quiz covering the topics of the lab. Be sure that you read the lab before you come to lab session and, even if you don't intend to complete the lab during the allotted time, come to the beginning of each lab session.
