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

Pre-requisites:

Recommended Text Book:

 Microbiology: An Introduction Global Edition                        

The Twelfth Edition of Tortora, Funke, and Case’s Microbiology: An Introduction focuses on big picture concepts and themes in microbiology, encouraging students to visualize and synthesize tough topics such as microbial metabolism, immunology, and microbial genetics. The text and accompanying resources also help students make connections between microbiology theory and disease diagnosis, treatment, and prevention.

Assessment Matrix

Other Information

Assessment information

This course is graded in accordance with competency-based assessment, but which also utilise graded assessment
CHD Competent with High Distinction (80 – 100%)
CDI Competent with Distinction (70 – 79%)
CC Competent with Credit (60 – 69%)
CAG Competency Achieved – Graded (50 – 59%)
NYC Not Yet Competent (0 – 49%)
DNS Did Not Submit for assessment

  • To pass the course you need to pass, on average, each type of assessment (exam, prac reports, and assignments etc.). For example, if there are two tests you need to have an average of 50% to pass. But you also need to have passed the other assessments as well. You can’t make up marks from one type of assessment to another (e.g. pass the tests but fail the prac reports).
     
  • Extension of time for submission of assessable work- A student may apply for an extension of up to 7 days from the original due date. They must lodge the application form (available on the web http://mams.rmit.edu.au/seca86tti4g4z.pdf ) at least the day before the due date. The application form is emailed to the Program Coordinator (namrita.kaul@rmit.edu.au) Students requiring longer extensions must apply for Special Consideration (form available on the Web). For missed assessments such as exams- you (& your doctor if you are sick) must fill out a special consideration form. This form must be lodged at the HUB or online with supporting evidence (eg medical certificate), prior to, or within, 48 hours of the scheduled time of examination.
     
  • Late work that is submitted without an application for an extension will not be corrected
     
  • If you miss an assessment task due to unavoidable circumstances, you need to follow the procedure of special consideration and apply within the allowed time frame.
     
  • Students must attend at least 80% of practical classes. If you miss a prac class you should provide a copy of your medical certificate or other evidence (court appearance, funeral notice, statutory declaration) to the teacher.
     
  • Plagiarism- Plagiarism is the presentation of the work, idea or creation of another person as though it is your own. It is a form of cheating and is a very serious academic offence that may lead to expulsion from the University. Plagiarised material can be drawn from, and presented in, written, graphic and visual form, including electronic data and oral presentation. Plagiarism occurs when the origin of the material used is not appropriately cited.
    It also occurs through enabling plagiarism, which is the act of assisting or allowing another person to plagiarise or to copy your own work. Please make sure you consider this carefully in completing all your work and assessments in this course and if you are unsure about whether you might have plagiarised, seek help from your teacher.
