This is a great course with tons of valuable info. The peer-review projects are very hands-on, and you learn a lot by doing that. However, I wish there were more explanations for certain things (for example, for the experiments section) - or at least, more resources to get further info. Also, for Assignment 3, it would have been very helpful to have the answer key, since there is some confusion around some of the answers.

Overall the information and exercises were good. The introduction to A/B testing was great and provides a good base layer of knowledge for the experimenting and analysis section of the IxD program. I would say that the week 3 assignment was frustrating as a grader since the rubric seemed to ask for very specific answers when the questions allowed for broader interpretation.

The exercises are very confusing to submit and to rate (peer rate review, sometimes too long questions and you lot the commitment). I would like that the teacher had a much linear methodology through the Specialization, in many moments it feels like he´s losing the objectivity.

It would be nice to reinforce the main concepts, instead of doing mathematic equations...

The Chi Square lecture was hard to follow. I took elementary statistics in college 20 years ago and got an A, but the lecture jumped and skipped explaining things. the video seemed to have been edited when Scott was about to explain something. Sometimes he didn't really explain somethings. The other lectures were very helpful and have helped me already.

I believe the valuable principles methods in this course would be very useful when this course is placed after courses that already taught students how to navigate through the design process up to prototyping.

When it's like this once one completed prototyping courses and is ready to test their prototypes they should come back and review this course.

This class was insanely insightful, and I found many of the topics covered very interesting and fascinating — towards the end of the course, specifically around designing experiments, I found that whole terrain to be pretty difficult to comprehend. I think the lectures have opportunities for improvement here.

Overall, the course is excellent, though if you take the whole specialization, the last week on doing A/B testing is copying another course's material - Running and Analyzing experiments. Other than that, the course is excellent, lots of examples and literature to read on your own pace.

The course is very useful, but the information is a bit hard to digest, especially the problem. Even though I watched the videos several times, I still did not understand some decisions you made in solving it. But I am a better person because of it! Thank you

Great for the first 2 weeks of class, the third week seemed really unbalanced though and all of the sudden was about 4x the amount of time to watch videos. I wouldn't have minded if the same material was spread to an extra week.

O curso passa conceitos bem básicos de design de interface, ux e etc. É interessante para quem quer ter um primeiro contato, as aulas são boas e o professor explicar de uma forma super tranquila de entender. Gostei bastante.

Design Principles has been meticulously structured, although, I'd have loved to lean more on Typography. One feedback to Professor will be to update his content and include more contemporary examples.

The course is designed well. Need more details on Chi-squared and AB testing. Overall it is very informative and helpful. Thank you

If you do not have experience with data analysis (specifically speaking Pearson's chi square technique), you might struggle like me.

Good course. The leactures could be better structured, but with some complementary reading and insistence, you bust right through.

Great, if brief course. Some occasionally ill-worded test questions. But this course piqued my interest for the ones that follow.

Just in week 1, this course has me examining and evaluating things I normally would take for granted...including work arounds!

Overall it was mostly good but the maths was not well enough explained and some of the course materials felt out of date.

Some of the evaluation methods just allow other people how doesn't do to much work to just pass...

A very good learning course. The content could be more in depth to get a better understanding.

The first assignment was very confusing in terms of what was required, and it should be fixed.

Everything is great apart of the third week assignment. I guess it needs to be changed.

Gave basic introduction to design principles but the assignments were very engaging

The course overall was good but the assignment instructions were not clear enough

very good course! the final was much more logical than the first course

This course really helped me understand what to ask of my Design team!
