Our feedback to You

Types of feedback you can expect to receive in this unit are:
  • Informal feedback on progress in labs/tutes
  • Graded assignments without comments

Your feedback to Us

Monash is committed to excellence in education and regularly seeks feedback from students, employers and staff. One of the key formal ways students have to provide feedback is through SETU, Student Evaluation of Teacher and Unit. The University's student evaluation policy requires that every unit is evaluated each year. Students are strongly encouraged to complete the surveys. The feedback is anonymous and provides the Faculty with evidence of aspects that students are satisfied and areas for improvement.

For more information on Monash's educational strategy, and on student evaluations, see:

Assessment Requirements

Assessment Policy

To pass a unit which includes an examination as part of the assessment a student must obtain:

  • 40% or more in the unit's examination, and
  • 40% or more in the unit's total non-examination assessment, and
  • an overall unit mark of 50% or more.

If a student does not achieve 40% or more in the unit examination or the unit non-examination total assessment, and the total mark for the unit is greater than 50% then a mark of no greater than 49-N will be recorded for the unit

Assessment Tasks


  • Assessment task 1
    Assignment 1 - Specification
    A proof-discharged Event-B specification of a problem (exact problem to be advised).

    This assignment is administered in two parts.  Part 1 is about defining the various parameters of the specification (in fact, a requirements analysis), and Part 2 is about coding the Event-B specification in Rodin and LaTeX.  The two parts will be offered separately, so that feedback may be returned on Part 1, before students complete Part 2.

    Assignment release date Week 2.
    20% (Parts 1 and 2 = 10% each)
    Criteria for assessment:

    Correctness and completeness of specification.

    Discharge of all proof obligations (mechanically or manually).

    Declarative style of specification.

    Due date:
    Part 1 due Friday Week 5, Part 2 due Friday Week 7
  • Assessment task 2
    Assignment 2 - Refinement
    A proof-discharged Event-B refinement of the specification begun in Assignment 1.

    Assignment 2 will extend the functionality of the specification developed in Assignment 1. 

    Assignment release date Week 7.
    Criteria for assessment:

    Correctness and completeness of specification.

    Discharge of all proof obligations (mechanically or manually).

    Declarative style of specification.

  • Assessment task 3
    Tutorial Exercises
    Students will be given exercise questions during each tutorial and asked to provide solutions for them.
    Criteria for assessment:

    Student attendance and completion of exercises.

    Quality or correctness of solutions to questions (demonstrates understanding of the learning materials).

    Due date:


  • Examination 1
    2 hours
    Type (open/closed book):
    Closed book

Assignment submission

It is a University requirement (http://www.policy.monash.edu/policy-bank/academic/education/conduct/plagiarism-procedures.html) for students to submit an assignment coversheet for each assessment item. Faculty Assignment coversheets can be found at http://www.infotech.monash.edu.au/resources/student/forms/. Please check with your Lecturer on the submission method for your assignment coversheet (e.g. attach a file to the online assignment submission, hand-in a hard copy, or use an online quiz).
