Discussion section

The goal for the discussion section is to allow you to review lecture topics in more detail and discuss strategies to solve homework problems, both under the guidance of the TA.

The discussion sections will take place in the lab BE 162.

Labs
 

Remember: You will work through three hands-on simulation applets on metals and semiconductors, respectively. See the links below in the lab schedule. After working through the simulations on semiconductors, you need to take the associated applet quiz by the time the report for the accompanying experiment is due. The quiz will be distributed by the TA during the lab sessions.

Here is a tutorial that illustrates how to use the applet simulations.

The applets count 50% towards the grade for that lab (Semiconductor conductivity).

Course Objectives
The fundamental electrical, optical, and magnetic properties of materials, with emphasis on semiconductors: chemical bonds, crystal structures, energy bands. Electrical and thermal conduction. Optical and magnetic properties. Students must concurrently enroll in course145L.

Course Prerequisites
EE145/L is a required course for EE undergraduates. Other Engineering or Science majors with proper prerequisites are welcome to enroll. Prerequisites (or equivalent at community college) are: (Physics 5abc or 6abc; Math (differential equations)).

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 is expected 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 and lecture. 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.

Working Together
You are encouraged to work in groups and discuss the homework assignments. However, each has to write his/her own solution and fully understand them.

Learning Objectives
A set of Learning Objectives is attached. These Learning Objectives (LO) are based on a list prepared by Prof. Emily Allen from San Jose StateUniversity. All of the course assignments (which includes lectures, homework assignments, lab assignments, in-class learning exercises,and lab reports) are designed to help you learn the material and complete the learning objectives. We recommend that you review the LOs weekly and highlight the ones you have achieved that week.This will help keep track of your progress in the course. The LOs under each topic may not be addressed all at once or even the same week of class.

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.Passing the final is mandatory in order to pass the class.

Academic Dishonesty and Cheating:

Any confirmed academic dishonesty including but not limited to copying homeworks or cheating on exams, will result in a no-pass or failing grade. You are encouraged to read the campus policies regarding academic integrity and dishonesty. Examples of cheating include (but are not limited to):

  • Sharing or copying results or other information during an examination.
  • Working on an exam before or after the official time allowed.
  • Submitting homework that is not your own work.
  • Reading another student's homework solution before it is due.
  • Allowing someone else to read your homework solution before the assignment is due.
  • Plagiarism or copying of homework/lab reports.
  • Use homework solutions from previous years.
  • Use lab reports from previous years.

If there is any question as to whether a given action might be construed as cheating, see me before you engage in any such action or check the university policies on academic dishonesty.
