Q3 Grade Distribution 2017/2018

Today, we are closing the 3Q grading period for the 2017/2018 school year. I have a total of 134 students with 50 of them enrolled in either Robotics 1 or Robotics 2.

Through my career, I have seen many students slip with their grades during this grading cycle. Regretfully, this trend has not abated much this year.

Robotics 1, Robotics 2, and Computer Science 2 have 100% of students passing. But the more curriculum-based courses have failures.

As you can see, Computer Science 1 has an overall failure rate of 13.33% (4 of 30 students). 75% of those failures come from one class period as a result of failure to complete a major multi-part project involving 2-dimensional arrays in Python.

The vast majority of the class (73%) received an A. The majority of those (63%) came from a single class period.

All-in-all, I am happy with the performance of both sections as we had some difficult concepts to cover during this grading period.

As you can see, Principles of Applied Engineering has an overall failure rate of 4.26% (2 of 47 students). The failures are evenly distributed between both sections of this course.

One section comprised 60% of the A’s, 42% of the B’s and 55% of the C’s. The other section was 40%, 58%, and 45% respectively.

This grading period, we covered mechanical, materials, and electrical engineering. Many students struggled with mechanical engineering and their grades reflected those challenges.

Interactive Circuits Lab

Today in PAE, we did an interactive circuits lab. I assigned the students to create 3 different circuits from the PHET Interactive Circuit Construction Kit: DC – Virtual Lab hosted by University of Colorado – Boulder.

Circuit 1 was a simple series circuit consisting of two lights, two batteries, and a switch:

Circuit 2 was a somewhat easy series circuit consisting of one light, three batteries, a switch, and a 120 Ohm resistor:

Circuit 3 was a parallel circuit consisting of three lights, each controlled independently with a switch:

Circuit 4 was a parallel circuit identical to circuit 3, but had a series “master switch” in it:

Circuit 5 was a short circuit with an over-heated power supply:

The students appeared to have fun with the lab and were engaged the entire class time. Thank you UC-Boulder for this nice interactive tool!
