Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

All generic core units in the Cert IV and Diploma.

Course Description

This unit of competency covers the ability to interpret food test requirements, prepare samples, conduct pre-use and calibration checks on equipment and perform routine testing of raw food materials, in-process materials and final products. These tests will involve several measurement steps. The unit includes data processing and some interpretation of results and tracking of obvious test malfunctions where the procedure is standardised. However, personnel are not required to analyse data, optimise tests/procedures for specific samples or troubleshoot equipment problems where the solution is not apparent.

Details of Learning Activities

Students will study and develop basic skills in communicating ideas, collecting, planning analysing and organising information from theory and laboratory sessions in the course Perform Food Tests(ONPS5246C). Problem solving concepts will be explored through a range of analytical food tests and physical measurements.
Much of the underpinning theoretical knowledge and practical basis for this course has already been delivered in the prerequisites which include ONPS 5241 (Biochemical properties of food), ONPS 5237C(Perform basic tests),ONPS 5136(Perform microbiological tests). Students will study and develop further skills in problem solving in the practice of food science and technology. Food products and/or raw materials wll be processed by students either individually or working in teams simulating a food industry situation
The students will learn decision making concepts central to the:
• processing,
• testing
• and quality control of product samples and/or raw materials.
From this students will choose strategies and test various food products and or raw materials with minimal supervision. This subject will run in close conjunction with ONPS5247 Plan and Conduct a Research Project as the major assessment will be an individual report based on an investigation of a Food sample and/or Raw material that the student has either carried out individually or in a team For this reason it is important that students attend all sessions including lectures, small group discussions and practical laboratory discussions as well as partaking in any internet activity or other online activity that may be required from time to time.
This course is (as it should be) mostly student driven. The lecturers and or guests are the consultants to be utilised for advice. A log book or journal for notes and results is compulsory. This will be examined from time to time by the supervisor.

Assessment Tasks

The assessment tasks in this course do not carry equal weight, it is compulsory that students submit for all the assessments listed unless specified otherwise by the instructor. Students who are absent for a test, exam, oral etc will be given an opportunity for deferred assessment only when an application for Special Consideration has been submitted within 48 hrs.of the assessment date and Special Consideration has been granted. Assignments, reports etc will be accepted after the due date only when a student has successfully applied for an Extension of Time or Special Consideration. For further information go to the RMIT website or myRMIT Studies (Blackboard). Failure to apply for an Extension of Time or Special Consideration, may mean a failure in competency for this course.

Laboratory Decision Making 20%
Log Book / Journal Assessment 10%
Practical Work and/or Test 15%
Oral Presentation 10%
Food Analysis Research Report 40 %
100%

 Grading
Competency Achieved (CA) or Not Yet Competent (NYC) will awarded for each assessment task. 
 

* For a student to pass this course and gain a mark of 50%, the student must achieve CA for each (and all) of the preceding assessment tasks.

* For a student to gain a mark > 50% the student must
- satisfactorily complete, present all documentation required
- successfully complete the 3 practical tasks
- gain competency (CA) in all the above tasks
- sit the final theory based exam for a mark /50 added to the semester task mark, for a final % mark or 50%, whichever is greater.
(N.B. The final exam will be graded only if the student has already received CA for each (and all) the preceding assessment tasks.)

* If a student is unable to gain competency during the semester class time and class practical tests, competency may be gained by sitting the final theory test to demonstrate competency in the elements failed. If a student does achieve the desired level of competency in previously submitted assessment tasks, the student will gain a mark of 50% (and no higher), ie competent.

Other Information

Homework
The student will be required to undertake research and assessment practice outside of regular class times. Homework exercises are provided to the student to facilitate their learning in a self-paced manner and form part of the overall achievement of the competencies in this course. Students are reminded that they are expected to conduct an equal amount of time outside of class, research and furthering their understanding of the concepts being taught, as they do in class to be deemed competent in this course.

University Plagiarism Statement
Students are reminded that cheating, whether by fabrication, falsification of data, or plagiarism, is an offence subject to University disciplinary procedures. Plagiarism in oral, written or visual presentations is the presentation of the work, idea or creation of another person, without appropriate referencing, as though it is one’s own. Plagiarism is not acceptable. The use of another person’s work or ideas must be acknowledged. Failure to do so may result in charges of academic misconduct, which carry a range of penalties including cancellation of results and exclusion from your course. Students are responsible for ensuring that their work is kept in a secure place. It is also a disciplinary offence for students to allow their work to be plagiarised by another student. Students should be aware of their rights and responsibilities regarding the use of copyright material.
