    Admin Appendix B (Policies) → Policy on plagiarism

    Policy on plagiarism

    We encourage sharing, but you should share with everyone in the class, not just a selected group. That is,

    • You are not allowed to share individual assignments with classmates directly.
    • You are not allowed to share project-related things with other teams directly.

    You can even reuse each other's work subject to the 'reuse policy' given below.

    If you submit code (or adopt ideas) taken from elsewhere, you need to comply with our reuse policy.

    Detection:

    • Detecting plagiarism in code is quite easy. You are not fooling anyone by reordering code or renaming methods/variables.
    • As all your work is publicly visible on GitHub, sooner or later somebody will notice the plagiarism.

    Penalties:

    • For submissions not affecting marks: We make a record of cases of plagiarism but we do not take further action. Such plagiarism does not disadvantage other students. Therefore, we prefer to spend all available resources on helping honest students to do better rather than to chase after dishonest students. If you think you gain something by plagiarizing, go ahead and do it. It's your choice and it's your loss.
    • For the final project/exam: Any case of claiming others' work as yours will be reported to the university for disciplinary action.

    Admin Appendix B (Policies) → Policy on reuse

    Policy on reuse

    Reuse is encouraged. However, note that reuse has its own costs (such as the learning curve, additional complexity, usage restrictions, and unknown bugs). Furthermore, you will not be given credit for work done by others. Rather, you will be given credit for using work done by others.

    • You are allowed to reuse work from your classmates, subject to following conditions:
      • The work has been published by us or the authors.
      • You clearly give credit to the original author(s).
    • You are allowed to reuse work from external sources, subject to following conditions:
      • The work comes from a source of 'good standing' (such as an established open source project). This means you cannot reuse code written by an outside 'friend'.
      • You clearly give credit to the original author. Acknowledge use of third party resources clearly e.g. in the welcome message, splash screen (if any) or under the 'about' menu. If you are open about reuse, you are less likely to get into trouble if you unintentionally reused something copyrighted.
      • You do not violate the license under which the work has been released. Please  do not use 3rd-party images/audio in your software unless they have been specifically released to be used freely. Just because you found it in the Internet does not mean it is free for reuse.
      • Always get permission from us before you reuse third-party libraries. Please post your 'request to use 3rd party library' in our forum. That way, the whole class get to see what libraries are being used by others.
      • This also ensures you learn the ethics to attribute credits to the correct stake holders/owners.

    Giving credit for reused work

    Given below are how to give credit for things you reuse from elsewhere. These requirements are specific to this module  i.e., not applicable outside the module (outside the module you should follow the rules specified by your employer and the license of the reused work)

    If you used a third party library:

    • Mention in the README.adoc (under the Acknowledgements section)
    • mention in the Project Portfolio Page if the library has a significant relevance to the features you implemented

    If you reused code snippets found on the Internet  e.g. from StackOverflow answers or
    referred code in another software or
    referred project code by current/past student:

    • If you read the code to understand the approach and implemented it yourself, mention it as a comment
      Example:
      //Solution below adapted from https://stackoverflow.com/a/16252290
      {Your implmentation of the reused solution here ...}
      
    • If you copy-pasted a non-trivial code block (possibly with minor modifications  renaming, layout changes, changes to comments, etc.), also mark the code block as reused code (using @@author tags)
      Format:
      //@@author {yourGithubUsername}-reused
      //{Info about the source...}
      
      {Reused code (possibly with minor modifications) here ...}
      
      //@@author
      
      Example of reusing a code snippet (with minor modifications):
      persons = getList()
      //@@author johndoe-reused
      //Reused from https://stackoverflow.com/a/34646172 with minor modifications
      Collections.sort(persons, new Comparator<CustomData>() {
          @Override
          public int compare(CustomData lhs, CustomData rhs) {
              return lhs.customInt > rhs.customInt ? -1 : (lhs.customInt < rhs.customInt) ? 1 : 0;
          }
      });
      //@@author
      return persons;
      

    Adding @@author tags to indicate authorship

    • Mark your code with a //@@author {yourGithubUsername}. Note the double @.
      The //@@author tag should indicates the beginning of the code you wrote. The code up to the next //@@author tag or the end of the file (whichever comes first) will be considered as was written by that author. Here is a sample code file:

      //@@author johndoe
      method 1 ...
      method 2 ...
      //@@author sarahkhoo
      method 3 ...
      //@@author johndoe
      method 4 ...
      
    • If you don't know who wrote the code segment below yours, you may put an empty //@@author (i.e. no GitHub username) to indicate the end of the code segment you wrote. The author of code below yours can add the GitHub username to the empty tag later. Here is a sample code with an empty author tag:

      method 0 ...
      //@@author johndoe
      method 1 ...
      method 2 ...
      //@@author
      method 3 ...
      method 4 ...
      
    • The author tag syntax varies based on file type e.g. for java, css, fxml. Use the corresponding comment syntax for non-Java files.
      Here is an example code from an xml/fxml file.

      <!-- @@author sereneWong -->
      <textbox>
        <label>...</label>
        <input>...</input>
      </textbox>
      ...
      
    • Do not put the //@@author inside java header comments.
      👎

      /**
        * Returns true if ...
        * @@author johndoe
        */
      

      👍

      //@@author johndoe
      /**
        * Returns true if ...
        */
      

    What to and what not to annotate

    • Annotate both functional and test code There is no need to annotate documentation files.

    • Annotate only significant size code blocks that can be reviewed on its own  e.g., a class, a sequence of methods, a method.
      Claiming credit for code blocks smaller than a method is discouraged but allowed. If you do, do it sparingly and only claim meaningful blocks of code such as a block of statements, a loop, or an if-else statement.

      • If an enhancement required you to do tiny changes in many places, there is no need to annotate all those tiny changes; you can describe those changes in the Project Portfolio page instead.
      • If a code block was touched by more than one person, either let the person who wrote most of it (e.g. more than 80%) take credit for the entire block, or leave it as 'unclaimed' (i.e., no author tags).
      • Related to the above point, if you claim a code block as your own, more than 80% of the code in that block should have been written by yourself. For example, no more than 20% of it can be code you reused from somewhere.
      • 💡 GitHub has a blame feature and a history feature that can help you determine who wrote a piece of code.
    • Do not try to boost the quantity of your contribution using unethical means such as duplicating the same code in multiple places. In particular, do not copy-paste test cases to create redundant tests. Even repetitive code blocks within test methods should be extracted out as utility methods to reduce code duplication. Individual members are responsible for making sure code attributed to them are correct. If you notice a team member claiming credit for code that he/she did not write or use other questionable tactics, you can email us (after the final submission) to let us know.

    • If you wrote a significant amount of code that was not used in the final product,

      • Create a folder called {project root}/unused
      • Move unused files (or copies of files containing unused code) to that folder
      • use //@@author {yourGithubUsername}-unused to mark unused code in those files (note the suffix unused) e.g.
      //@@author johndoe-unused
      method 1 ...
      method 2 ...
      

      Please put a comment in the code to explain why it was not used.

    • If you reused code from elsewhere, mark such code as //@@author {yourGithubUsername}-reused (note the suffix reused) e.g.

      //@@author johndoe-reused
      method 1 ...
      method 2 ...
      
    • You can use empty @@author tags to mark code as not yours when RepoSense attribute the to you incorrectly.

      • Code generated by the IDE/framework, should not be annotated as your own.

      • Code you modified in minor ways e.g. adding a parameter. These should not be claimed as yours but you can mention these additional contributions in the Project Portfolio page if you want to claim credit for them.

     

    At the end of the project each student is required to submit a Project Portfolio Page.

    • Objective:

      • For you to use  (e.g. in your resume) as a well-documented data point of your SE experience
      • For us to use as a data point to evaluate your,
        • contributions to the project
        • your documentation skills
    • Sections to include:

      • Overview: A short overview of your product (can use the product introduction you wrote earlier) to provide some context to the reader.

      • Summary of Contributions:

        • Code contributed: Give a link to your code on Project Code Dashboard, which should be https://nuscs2113-ay1920s1.github.io/dashboard/#=undefined&search=github_username_in_lower_case (replace github_username_in_lower_case with your actual username in lower case e.g., johndoe). This link is also available in the Project List Page -- linked to the icon under your photo.
        • Features implemented: A summary of the features you implemented. If you implemented multiple features, you are recommended to indicate which one is the biggest feature.
        • Other contributions:
          • Contributions to project management e.g., setting up project tools, managing releases, managing issue tracker etc.
          • Evidence of helping others e.g. responses you posted in our forum, bugs you reported in other team's products,
          • Evidence of technical leadership e.g. sharing useful information in the forum
      • Relevant descriptions/terms/conventions: Include all relevant details necessary to understand the document, e.g., conventions, symbols or labels introduced by you, even if it was not introduced by you.

      • Contributions to the User Guide: Reproduce the parts in the User Guide that you wrote. This can include features you implemented as well as features you propose to implement.
        The purpose of allowing you to include proposed features is to provide you more flexibility to show your documentation skills. e.g. you can bring in a proposed feature just to give you an opportunity to use a UML diagram type not used by the actual features.

      • Contributions to the Developer Guide: Reproduce the parts in the Developer Guide that you wrote. Ensure there is enough content to evaluate your technical documentation skills and UML modelling skills. You can include descriptions of your design/implementations, possible alternatives, pros and cons of alternatives, etc.

      • If you plan to use the PPP in your Resume, you can also include your SE work outside of the module (will not be graded)

    • Format:

      • File name: [TEAM_ID]-[Your Name]PPP.pdf e.g., [AY1920S1-CS2113T-F10-3][John Doe]PPP.pdf

      • Use one-half spacing between the lines for legibility

      • Follow this example. A PDF version of the same has been uploaded on LumiNUS.

      • 💡 You are free to choose any (collaborative) software to write the documents. However, try to follow the format of the sample user guide, developer guide and PPP given.

      • Do note that extra effort is needed in duplicating and maintaining consistency across UG/DG and PPP. This is a cost of not using automated document generation.

      • It is assumed that all contents in the PPP were written primarily by you. If any section is written by someone else  e.g. someone else described the feature in the User Guide but you implemented the feature, clearly state that the section was written by someone else  (e.g. Start of Extract [from: User Guide] written by Jane Doe).  Reason: Your writing skills will be evaluated based on the PPP

    • Page limit:

      Content Limit
      Overview + Summary of contributions 0.5-1 (soft limit)
      Contributions to the User Guide 2-4 (soft limit)
      Contributions to the Developer Guide 3-5 (soft limit)
      Total 5-8 (strict)
      • Reason for page limit: These submissions are peer-graded (in the PE) which needs to be done in a limited time span.

      • If you have more content than the limit given above, you can give a representative samples of UG and DG that showcase your documentation skills. Those samples should be understandable on their own. For the parts left-out, you can give an abbreviated version and refer the reader to the full UG/DG for more details.

      • It's similar to giving extra details as appendices; the reader will look at the UG/DG if the PPP is not enough to make a judgment. For example, when judging documentation quality, if the part in the PPP is not well-written, there is no point reading the rest in the main UG/DG. That's why you need to put the most representative part of your writings in the PPP and still give an abbreviated version of the rest in the PPP itself. Even when judging the quantity of work, the reader should be able to get a good sense of the quantity by combining what is quoted in the PPP and your abbreviated description of the missing part. There is no guarantee that the evaluator will read the full document.

    Admin Appendix B (Policies) → Policy on help from outsiders

    Policy on help from outsiders

    In general, you are not allowed to involve outsiders in your project except your team members and the teaching team. However, It is OK to give your product to others for the purpose of getting voluntary user feedback. It is also OK to learn from others as long as they don't do your project work themselves.

    Admin Exams

    There is no midterm.

    The final exam has two parts:

    • Part 1: MCQ questions (30 minutes, 25 marks)
    • Part 2: Essay questions (1 hour 30 min, 30 marks)

    Both papers will be given to you at the start but you need to answer Part 1 first (i.e. MCQ paper). It will be collected half an hour after the exam start time (even if arrived late for the exam). You are free to start part 2 early if you finish Part 1 early.

    Final Exam: Part 1 (MCQ)

    Each MCQ question gives you a statement to evaluate.

    An example statement

    Testing is a Q&A activity

    Unless stated otherwise, the meaning of answer options are
    A: Agree/True. If the question has multiple statements, agree with all of them.
    B: Disagree/False. If the question has multiple statements, disagree with at least one of them
    C, D, E: Not used

    The exam paper has 50 questions. All questions carry equal marks.

    The weightage of the Part 1 of the final exam is 25 marks out of the total score of 100.

    Note that you have slightly more than ½ minute for each question, which means you need to go through the questions fairly quickly.

    Given the fast pace required by the paper, to be fair to all students, you will not be allowed to clarify doubts about questions (in Part 1) by talking to invigilators.

    • If a question is not clear, you can circle the question number in the question paper and write your doubt in the question paper, near that question.
    • If your doubt is justified (e.g. there is a typo in the question) or if many students found the question to be unclear, the examiner may decide to omit that question from grading.

    Questions in Part 1 are confidential. You are not allowed to reveal Part 1 content to anyone after the exam. All pages of the assessment paper are to be returned at the end of the exam.

    You will be given OCR forms (i.e., bubble sheets) to indicate your answers for Part 1. Indicate your student number in the OCR form.

    The exam paper is open-book: you may bring any printed or written materials to the exam in hard copy format. However, given the fast pace required by Part 1, you will not have time left to refer notes during that part of the exam.

    💡 Mark the OCR form as you go, rather than planning to transfer your answers to the OCR form near the end.

    💡 Write the answer in the exam paper as well when marking it in the OCR form.  Reason: It will reduce the chance of missing a question. Furthermore, in case you missed a question, it will help you correct the OCR form quickly.

    💡 We have tried to avoid deliberately misleading/tricky questions. If a question seems to take a very long time to figure out, you are probably over-thinking it.

    You will be given a practice exam paper to familiarize yourself with this slightly unusual exam format.

    Final Exam: Part 2 (Essay)

    Unlike in part 1, you can ask invigilators for clarifications if you found a question to be unclear in part 2.

    Yes, you may use pencils when answering part 2.

    The weightage of the Part 2 of the final exam is 15 marks out of the total score of 100.

    Past exam papers will be uploaded on IVLE.

    Admin Appendix C (FAQs) → What if I don’t carry around a laptop?

    What if I don’t carry around a laptop?

    If you do not have a laptop or prefer not to bring the laptop, it is up to you to show your work to the tutor in some way (e.g. by connecting to your home PC remotely), without requiring extra time/effort from the tutor or team members.

    Reason: As you enjoy the benefits of not bring the laptop; you (not others) should bear the cost too.

    Admin Appendix B (Policies) → Policy on publishing submissions

    Policy on publishing submissions

    The source code are publicly available and are available for reuse by others without any restrictions. 
    Is publishing submissions unfair to the team? We don't think so. If you were the first to think of something your peers are willing to adopt later, that means you are already ahead of them and they are unlikely to earn more marks by adopting your ideas.
