Then, I would have the homework cast as an Eclipse Java Project for each assignment. In each raw assignment, include something like theDropBoxTest code that gives a testing framework.
Assignment 2 Submissions - Technologies and Politics of Control
Again, it just makes life easier. You could even bare bones testing assertions and have the students add their own stuff in which is what I eventually wound up doing. The test, themselves show how you expect the whole thing should work.

Then, we students would import the homework as a new project, do what needs to be done and just submit the code developed. The point of including the testing framework is that ambiguities or interpretational variations can much reduced in what we are being asked to do. I found that all my problems pretty much came down to thinking about how I would implement the functionality of the specification quite differently then how it needed to be done to fit into the grading framework. There is really a lot of hidden specification in the grading framework.
I could not have done the assignments without the DropBox The grading process gave very little hints about what might have gone wrong, which is ok for grading, but not so useful for debugging the problem. I think this kind of project approach would reduce a fair amount of the forum questions, and, at the same time, make this course more accessible for Java nubies. The lectures were spot-on, with sufficient detail and background to make everything understandable.
The first programming assignment was very difficult, however. I would strongly suggest that the Coursera team break this assignment into chunks, with small steps to accomplish along the way leading to the final result as currently envisioned and provide some guidance to help students understand what is needed and perhaps how to structure some of the code. I found that assignment nearly impossible to complete, but was eventually successful.

Assignment 2 was almost trivial in comparison, and 3 was somewhat challenging but not nearly as daunting as the 1st assignment. Finally, I was surprised that a certificate was not offered after successful completion of the course. This was one of the longest and most challenging, when the programming assignments are factored in of ANY course I've taken on Coursera and, I've taken a lot.
As soon as the 3rd assignment was completed in week 7, the course thinks everything required has been accomplished and declares victory. I still need to watch about 3 hours of videos to really finish the course which I fully intend to do! The course covers not just mechanics of bitcoin and some altcoins per se, but also explains philosophy behind block chain, reasons why particular design decisions were made, alternatives considered and how the system protects itself from possible attacks.
The material is also interesting as an application of different crypto primitives but their nature is not covered. Assignments are cool, but One of them helps to understand alternative approach to reach distributed consensus which is not covered in the lectures see ripple. It's literally a miracle that Coursera allows me to study from perhaps the best professors on blockchain in the world. It's not a joke how big of an opportunity this is. And although I'm not into college yet, and even though I don't even plan to opt for a STEM major, I do have a basic knowledge of programming and I'm going to try my best to make the most of this god-send gift.
Excellent intro course into blockchain technology and potential applications could be built on top of it. Also, if you're technical there are programming assignments which reinforce your learning. Sometimes assignments not so explicit. Would be a plus to be able to run some unit tests locally.
Course content good but labs difficult to work with as no offline unit tests were provided which made debugging painful. If possible I would rate a 4. The lecturers are very good and comprehensive compared to all other sources I found in the web at explaining how cryptocurrencies especially BTC work and what the up- and downsides are. The workload for lecture videos is pretty low for each week h a week which makes the learning targets pretty easy to achieve in the proposed time. I found the programming assignments quite difficult when beginning with each one, since one needs to read and understand most of several hundred lines of starter code and also needs to understand the task setting which uses a somewhat different terminology than used in the lectures.
Also for assignment 1 and 3 there is no simple test code provided to at least partially test your code submission candidates. That makes it hard to debug in case of small logical errors that cannot be detected by the compiler but probably break the complete solution and result in a very low score.

I had no experience in Java programming before the start of this course but with a one day crash course of Java for Python programmers I managed to complete all assignments in time and learn at least the basic principles of Java, which is nice for itself. Each assignment is expected to take 3h by the creators of the course. The come up with a high score not just passing I needed to invest about hours for each assignment which is probably but not exclusively due to the little knowledge of Java.
Nevertheless I would encourage the creators of this course to use Python assignments for future courses since this would make prototyping a lot easier due to it's interactivity and attract more students without having real downsides at least to my knowledge. All in all I really enjoyed this course and would like to thank all lecturers and the Princeton University for making this course accessibly free of charge for everybody.
Thanks a lot! Great course to get introduced into Bitcoin and Blockchain technologies at technical level. Review this product Share your thoughts with other customers. Write a product review. Customer images. See all customer images. Top reviews Most recent Top reviews. Top review from India.

Google classroom is a creative and a very good platform for students and teachers to take tests and to submit assignments but there is a very big issue in this app that is when I submit a assignment it takes too much time to upload the picture and when I go back to home screen without closing the app from recents the app refreshes and everything written in it gets removed.
Today , I had a test in which I completed my test but when I wanted to upload the pictures it was almost 10 minutes before the submission time but when I started to upload pictures it took me half an hour to upload almost 6 pictures and i was not able to send the test answers on time. I am very unpleased for this issue please solve it as soon as possible.
This app is wonderful and it was very useful during the lockdown when we could not go to school. It functions well but it has some issues that need to be fixed. Slow: When I open the app, it takes a lot of time to open and that is really annoying. When our teachers give us any study material or assignment, it takes time to load.
Crashes a lot: This app crashes a lot and it is really irritating. The thing is both Google Classroom and Google Meet crash often and that annoys both teachers and students. Kindly address to these problems. Just why??? The following data may be collected and linked to your identity:.
