Small Group Discovery Experience
Groups of 4 students
Project on microbial activities- identification of spoilage organisms on a food item, planning of experiments, performing experiments, analysing results, preparing poster as a group and individual journal, peer assessment.
Interactions with mentors- meet the mentors in the practical session (1 x 2hrs)
mentors attend practical sessions in specified week (2 occassions up to 4 hrs over 3 weeks)
mentors attend poster presentation session (min conference)( 1 x 1 hr)
Students undertake project work in weeks 4-6 inclusive in groups of 4. Each group selects a topic to explore the beneficial and deleterious activities of microorganisms, then plans and conducts experimental work in the laboratory. Students will work in conjunction with an academic mentor. Each group presents their work as a poster which is presented academic staff and peers at a mini-conference.
Students are required to assess their contribution and that of their group members to the project as part of the assessment (peer assessment).
Each student documents his or her individual contribution through a journal.
Guidance is provided throughout by academic staff and demonstrators and exemplars of posters and journals are provided.
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.

Assessment Related Requirements
To pass the course, a student must obtain 40% for the written exam(s) (i.e. 24 out of 60). Students who miss assessed practicals because of illness, bereavement (or other compassionate grounds) or unavoidable commitments are given an assignment in lieu of the assessment piece (replacement assessment). No other additional assessment is available for Practical Components.
Assessment DetailWritten examinations
The written exam(s) account for 50% of the final mark (30% is for microbiology and 20% for biotechnology). The exam will assess the students’ knowledge, their ability to apply knowledge and their critical analysis skills. Questions will be set by each lecturer, with marks according to the number of lectures given. There is a non-compulsory mid-semester written examination in
week 8 (worth potentially 30% of the final course grade).
There will be a non-compulsory mid-semester examination in week 8, covering material presented in weeks 1-6 (microbiology), potentially making up 30% in total of the final grade for the course. The mid-semester exam will be redeemable in the end of semester exam; there will be a separate section in the final exam (section A) that will correspond to the material covered in the
mid-semester exam. Students may choose not to complete this section of the final exam, in which case the mid-semester exam marks will be used automatically to calculate the final grade and the final exam will have a weighting of 20%. If students attempt both the mid-semester exam and the corresponding section in the final exam, the best mark of their two attempts will be used to
calculate the final grade. If students do not attempt the mid-semester exam, then they must attempt the corresponding section in the final exam, in which case the final exam weighting will be 50%.
Students will be offered the opportunity to review their answers in the non-compulsory mid-semester examination with academic staff. Replacement/alternative assessment is not available for the mid-semester exam except on medical or compassionate grounds.
An end-of-semester written examination will be used to assess, summatively, understanding the course material. The examination will be divided into two parts:
A. An optional section consisting of questions corresponding to those in the non-compulsory mid-semester exam (potentially 30% if used to redeem mid-semester exam mark).
B. A compulsory section consisting of material covered in weeks 7-12 (biotechnology).
Assessment of practical and work:
Formative assessment; tutorial classes will include diagnostic and formative assessment to review information and understanding of the course material. Tutorial discussion topics and quizzes will be posted on MyUni.
Summative assessment and submission of work for assessment; instructions for format, content and submission of practical reports, tutorial work and project work will be provided by the lecturer concerned.
Practical reports, account for 30% of the final mark as follows:
Practical 1: Single and multi-celled microorganisms; individual report,
template distributed in class, data entered in practical sessions 2 &
3 and tutorial 2, due at end of practical 3, (5% of final mark), addresses
learning objectives 2, 3, 8, 9.
Practical 2: Plant disease; prepared in pairs, template distributed in class,
report due at end of practical 5, (5% of final mark), addresses learning
objectives 1, 2, 3, 4, 8, 9.
Microbiology project report
Microbiology project report (group poster). Microbial activities - experiments and interpretation; presented as one poster per group
of students, instructions in practical manual and tutorial 3, formative review of progress in tutorial 4, due 10.10 am on specified date, 15% of final mark, addresses learning objectives 1, 4, 8, 9, 10
Practical 3: Identifying Genetically Modified Organisms (GMOs); individual report including Aims, Introduction, Results, Discussion & Conclusion, due in week 10, (10% of final mark), addresses learning objectives 6, 7, 8, 9.
Practical 4: Purification and use of recombinant proteins; individual report focusing on data presentation and summarising key points from four different, but related experiments. A formative assessment component is included to provide students with feedback due in week 10 before submission of the final assessment task in week 12, (10% of final mark), addresses learning
objectives 6, 7, 8, 9.
Practical reports will be promptly assessed to provide continual feedback to students and a sense of progressive accomplishment in the course. Students will receive written feedback on each of practical reports submitted for assessment.
Formative online pre-laboratory quizzes: completion before the laboratory class, including safety information relevant to the practical and activities including practice calculations, plotting graphs in Microsoft Excel and writing informative figure legends. There is one pre-laboratory quiz for each practical (4 for microbiology and 4 for biotechnology), due before the practical class, addresses learning objectives 1, 2, 3, 4, 5, 6, 8, 9.
A completed assessment cover sheet must be attached to each practical/tutorial report. Practical/tutorial reports are submitted in class, online to Turnitin or to a designated drop box. Students will be notified in class where to submit reports for assessment.
A student who misses an assessed exercise of whose work is impaired through illness or equivalent may be offered a replacement assessment task for the microbiology section of the course.
Staff endeavor to return marked assessments and provide feedback to students within 2 weeks of submission.
Late submission of assessments: If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that the assignment is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.
Grades for your performance in this course will be awarded in accordance with the following scheme:

Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.The University places a high priority on approaches tolearning and teaching that enhance the student experience.
