Multistaging of Java Code Examples At StackOverflow

Violette's Multi staging functionality

To evaluate Violette's multi-staging functionality, I have put together the following experiment. Please follow all of the instructions below:

PREREQS

Make sure you have

1. Google Chrome latest version installed on your computer.
2. Uninstalled any previously installed Violette from Chrome.
3. Installed Violette-multi-staging-mode on Chrome¹.

THE TASK

There will be 6 Java code examples to review and understand. For each example, there will be a link to it. This link will take you to a page containing a StackOverflow's accepted answer. This answer contains some Java code.

For each linked Java code example, do the following

1. You, the participant, must click on a linked code example. This link will take you to the example's Q&A page at StackOverflow.

   Note: Don't click on the next link if you have not finished reviewing and understanding the previous Java code example

2. Once you are on that page, your goal is to review and understand the Java code example in the accepted answer using multi-staging².

   You'll activate this functionality by clicking on the stage button. This button is located on the top right corner of Violette. Each stage is represented as named button. Stages are presented in ascending order; i.e., starting from 0 to n where n is the maximum number of stages that can be extracted from the code example.

3. After you've finished reviewing and understanding the Java code example, please click on the Bring it to Destop button and then provide a description of the goal behind this code example and the reason for using it. You may include fitness of purpose, abstractions, usage protocols, etc. For example, imagine you reviewed an implementation of the PageRank algorithm. Then a possible description of this algorithm is "It models the behavior of a random web surfer using a Markov chain"

4. Lastly, after bringing the Java code example to your desktop, please comeback to the Violette and then click on the "?" mark button on the bottom right corner of Violette. This will take you to an online questionnaire. This questionnaire will help us capture your understanding of the code example you've just curated.

5. Close the Q&A page and then comeback to Violette. Once there, click on the next Java code example to curate.

TASK EXPECTATIONS

We expect the following throughout the task:

1. We expect you to review and understand a total of 6 Java code examples, provided in this page.

2. We expect the whole task be done within 1 hr and 30 minutes.

3. We expect the subjects to use only the resources available on the question-answer page to complete the task; i.e., no external resources like Wikipedia.

LET'S GET STARTED

Before starting, please watch the following video. This video introduces violette and the multi-staging functionality and UI.

Footnotes

1. Open Google Chrome and on the Url bar type chrome://extensions. Look for violette-staging-no-summarization.crx. Get the file and then drop it on the Chrome extension area. Press the Add button and you're done. ↩

2. Multi staged code examples are divided into a series of intermediate phases, presenting lower-level modules (supporting modules) before higher-level modules (main modules). ↩
