About the ECE 313 Concept Matrix

FAll 2014


Rather than turning in problem sets, you are expected to read the notes and attempt to solve the short answer questions and many of the even numbered problems in the notes. The concepts to be covered, along with the sections of the notes you should read, and the short answer questions (SAQs) and problems you should solve, are listed for each week in the large table on the main course web page. The solutions to the even numbered problems are included in the appendix of the notes. Solutions will not be collected from you, but you are strongly encouraged to work out the problems on your own; only looking at the solutions when you are truly stuck. Learning how to use probability theory is best done through problem solving.

Making the most of classroom time

We encourage you to start the required reading and familiarize yourself with the concepts to be learned for the week before the beginning of the week, and perhaps view some of the short videos for the material. While we hope you find the videos useful, the videos are not intended to be a replacement for reading the notes. Typically the videos focus on problem solving, whereas you need to read the notes for the basic theory that is applied.

Mastering concepts through problem solving and team work

In addition to the quizzes and exams, you can demonstrate your mastery of the concepts in another way. It will be your responsibility to learn and master the concepts through studying the notes, attending lectures and problem solving sessions during scheduled class meetings, solving homework problems (before checking the solutions), attending office hours as needed, and discussing the concepts and problems with your classmates. You will then demonstrate your mastery of the concepts during office hours, through small group or individual question and answer demonstrations with a TA or instructor. You are encouraged to learn the concepts for a given week early in the week, because it will help you on the quiz. However, you can still earn credit for learning concepts up until 7 pm Tuesday (the deadline is 7 pm Wednesday, September 3, for the first week's concepts, due to the Labor Day holiday. That is the same day as Quiz 1. The deadline for the second week's concepts is 7pm Tuesday, September 9, the day after Quiz 2, and all following deadlines are similarly on Tuesdays. ) The concept matrix itself (see link at the bottom of this page) indicates which concepts each student (listed by NetID only) has mastered. In the concept matrix, a “1” in a box in the row after your NetID indicates that you know a particular concept.    A “5” in a box indicates that you know the concept for that box, and also the concepts in the four boxes that follow it,  That is, a single entry of 5 is equivalent to 1 1 1 1 1. 

TIP: You can save time by demonstrating multiple concepts at one go--often the concepts for a given week are closely related. While we will try to adjust staffing hours to meet your needs, you might want to avoid lines that may grow shortly before the deadline for a group of concepts.

The protocol for concept matrix certification is as follows:

Participating in groups is an opportunity for collaboration and improving valuable communication skills. While it is not an absolute requirement for you to participate in a group, the course staff will give priority to groups, because it is only fair to give priority to groups of students who have each helped in the certification process by not only learning the concepts themselves, but in helping certify that others have learned them.

What if you are not available or not interested in getting certified for a concept?

In order to accommodate a broad range of learning styles, and to increase flexibility, the concept matrix points will be adjusted as follows. As mentioned above, if you are certified for a given concept by the deadline you get one point for that concept. If you do not get certified for a concept, you will receive partial credit T for the concept, where T is the fraction of points you score on the midterms and final exams. Specifically, the contribution of the concept matrix points to your final score in the course will be calculated as follows:

T=[15*(exam 1 percentage score) + 15*(exam 2 percentage score) + 30*(final exam percentage score)]/60

adjusted concept points = concept points + (50-concept points)*T

contribution to final score = 10% * (adjusted concept points)/50

The following table shows some examples to help you understand the formula.

Number of concepts certified T adjusted concept points contribution to final score (10% max possible)
50 any value of T 50 10%
0 70% (about average) (50)(70%)=35 7%
0 90% (strong test scores) (50)(90%)=45 9%
30 70% (about average) 30 + (20)(70%)=44 8.8%
40 70% (about average) 40 + (10)(70%)=47 9.4%
30 55% (below average) 30 + (20)(55%)=41 8.2%
10 55% (below average) 10 + (40)(55%)=32 6.4%
