Overview

Feedback is mostly positive. The strongest signal is that students say they actually learn something useful. Best for students who want substance, not a disposable elective.

Feedback Analysis

Feedback Analysishigh
Analysis based on student evaluations
Based on 89 comments across 3 sections

Feedback is mostly positive. The strongest signal is that students say they actually learn something useful. Best for students who want substance, not a disposable elective.

Student Reports
How hard is the A?
A is doable but not automatic
The signal here is more do-the-work-and-you-should-be-fine than easy-A chatter. Students do not describe the A as automatic, but the evidence also does not paint grading as punishing.
Homework Load
Moderate homework load
Homework load looks moderate. The recurring signal is steady weekly work, but not a course that turns every assignment into a grind.
Lecture Load
Lighter lecture burden
Student comments describe this as more discussion-, seminar-, or workshop-driven than lecture-dependent. The lecture burden itself does not sound like the main source of friction.
Strengths
Students repeatedly say the course teaches something concrete, whether that is content mastery, research skill, or a strong foundation.
Tradeoffs
There is no single dominant complaint theme, but the feedback is not uniformly glowing either.
Best fit for
Best for students who want substance, not a disposable elective.
Watch out for
A large share of the evidence comes from one instructor's version of the course, so this may not generalize cleanly.

Student Responses

I learned so much more about embedded systems, IOT, and was able to connect knowledge from other classes I have taken w which was nice.
Fall 2024 · Chen, Tingjun
I learned how systems in our world are connected to each other and collect data with each other. I learned how information is communicated and sent across space. I learned how devices are linked together to enable that information flow.
Fall 2024 · Chen, Tingjun
I developed an understanding of IOT and how different components integrate to create solutions. This class was great for learning how to integrate hardware and software and I gained an overall understanding of how many internet enabled devices work.
Fall 2024 · Chen, Tingjun
I learned how the internet "works"- routers, IP addresses, how to send things over the internet using different protocols I learned how to use an ESP32 with external sensors- gpio pins, timers, interrupts, mpu_6050, temperature sensor, humidity sensor, etc I learned how to read documentation (Datasheets, code repos) in order to use code and sensors I had never used prior to this class.
Fall 2024 · Chen, Tingjun
I learned a lot about how the world actually works—this class did a great job of covering the full stack of IoT development, from low level embedded systems coding to network architectures to server-side.
