![Page 13: Introduction to the Subject BIOL30001 Reproductive Physiology Reading:- LMS.unimelb.edu.au - Johnson MH (2013) Essential Reproduction 7 th Edition,](https://reader030.fdocuments.net/reader030/viewer/2022033019/56649ef25503460f94c03852/html5/thumbnails/13.jpg)
Subject Outline• Generic skills:
– Attain knowledge from lectures, tutorials, observation and the literature
– use that knowledge to evaluate and communicate results
– access information in primary scientific literature– abilities to evaluate scientific evidence critically– skills in data interpretation, and identifying
alternative explanations
• We will assess your understanding – note learning is not enough.
![Page 14: Introduction to the Subject BIOL30001 Reproductive Physiology Reading:- LMS.unimelb.edu.au - Johnson MH (2013) Essential Reproduction 7 th Edition,](https://reader030.fdocuments.net/reader030/viewer/2022033019/56649ef25503460f94c03852/html5/thumbnails/14.jpg)
• Lectures- Mon, Tues, Weds, Fri– but Friday lec. slot mainly for tutes
(may run impromptu tutes in the extra slots)
• Tutorials– quizzes– structured learning exercises– raise questions on lecture content
Lecture: should NOT be “the process by which the notes of the lecturer become the notes of the student without passing through the mind of either”Focus on what is being said; ask questions…

• Assessment– 35% Seven online quizzes– 15% Literature review– 10% 50 minute mid-semester test– 40% end of semester exam

TIME: don’t rely on swotvac
• Don’t pretend that doing nothing in term then cramming for hours in swot vac is enough.
• This is a subject with a large amount of content, which is why we encourage you to review what you have learnt frequently (online quizzes).
![Page 22: Introduction to the Subject BIOL30001 Reproductive Physiology Reading:- LMS.unimelb.edu.au - Johnson MH (2013) Essential Reproduction 7 th Edition,](https://reader030.fdocuments.net/reader030/viewer/2022033019/56649ef25503460f94c03852/html5/thumbnails/22.jpg)
TIME: keep up to date
• WE ASSUME in Lecture 2 that you know the material covered in Lecture 1; In lecture 3 we assume Lecture 1 & 2….
… make sure you keep up-to-date with your revision and self-assessment
![Page 23: Introduction to the Subject BIOL30001 Reproductive Physiology Reading:- LMS.unimelb.edu.au - Johnson MH (2013) Essential Reproduction 7 th Edition,](https://reader030.fdocuments.net/reader030/viewer/2022033019/56649ef25503460f94c03852/html5/thumbnails/23.jpg)
TIME: do something every week
• Spread your time investment through the semester.
• We will encourage you to study regularly with approx. weekly quizzes (35% of assessment)
![Page 24: Introduction to the Subject BIOL30001 Reproductive Physiology Reading:- LMS.unimelb.edu.au - Johnson MH (2013) Essential Reproduction 7 th Edition,](https://reader030.fdocuments.net/reader030/viewer/2022033019/56649ef25503460f94c03852/html5/thumbnails/24.jpg)
TIME: don’t get behind
• If you get behind you will never really catch up! Spend some time after EVERY lecture and tute consolidating what you have learned.
• Use your textbook, our notes on LMS, Echo360, or other books or resources.

Sex and the echiuroid worm Bonellia
Echiuroid worm - Bonellia• Female worm is rock dwelling • Male lives inside the female’s uterus &
fertilizes her eggs• If larva lands on sea floor becomes
female• If larva lands on the proboscis of a
female - chemical attractants emitted• Larva will enter females mouth, migrate
to the uterus and differentiate into a male
