Teaching and course materials will be posted in MyUni (). Lectures will be recorded and posted on MyUni. Tutorial topics for microbiology will be posted for discussion. A series of videos demonstrating common microbiological techniques will be available on MyUni. Interative pre-laboratory activities using the software Articulate Storyline will be used in formative and summative assessment. Online quizzes will be available to help with review and revision (formative assessment).

Lectures are used to deliver content relevant to the specified course objectives. Lectures include the opportunity for open discussion, questions and problem solving activities. Selected biotechnology lectures are supported by formative pre-lecture online activities to support in class activities and discussions. The microbiology project work in weeks 4-6 allow students to synthesise and apply the skills learned in the course to address practical situations.

 

Tutorials aim to develop and support the material covered in the lectures as well as provide a forum for acquiring skills and knowledge necessary to complete the assessment tasks. The tutorials take the form of class discussions, demonstrations and problem-solving activities.

 

Practicals aim to apply the knowledge and skills covered in the lectures and tutorials linking theory to practice.

A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).

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.

Microbiology project work & presentation	Summative	15%	No	1-5,6,9,10
Non-compulsory mid-semester theory exam	Formative and Summative	0-25%	No	1-6
Final Written exam(s)	Summative	25-50%	Yes	1-8

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.

Written 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).

Mid-semester examination:
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.

Final examination:
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 work and presentation account for 15% of the final mark as follows:

Microbiology project report
(Poster, journal and peer assessment); microbial activities- experiments and interpretation, presented as a team poster and individual journal, instructions in practical manual and tutorial 3, formative review of progress in tutorial 4,  due on specified date in week 9, (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.

In response to positive feedback in an informal survey in 2012 and course SELTs in 2013 and 2014 (for the co-taught course Microbiology and Invertebrate Biology II), the non-compulsory, redeemable mid-semester exam, which was run as a trial in 2012, is retained.

In response to feedback from the program coordinator in 2016, timetabling has been changed so that the course remains on the same day for the entire semester to avoid clashes with courses on other campuses.
