Teaching Rationale And Relationship

Semester 1:
The use of lectures as the principle teaching method is an effective means to provide students with the acquisition of the sizeable and detailed knowledge base and facilitate understanding of the module material (IKO1-8).
Practical sessions provide the forum for the knowledge and understanding developed through formal lectures to be integrated into coursework exercises and practical laboratory classes (ISO1-4).
The field trip to a marine production facility (e.g. a ship repair yard, offshore yard, etc.) provides an opportunity to introduce students to a shipyard environment and reinforce the relevance of taught material.

Semester 2:
Ship stability concepts are introduced in lectures (IKO9- 13). Specific numerical problems are given at the end of each lecture. Tutorials are used to review numerical examples (IKO9,11,12) and (ISO5-7). Laboratory experiment demonstrates the practical aspects of stability evaluation (ISO7-8).
Fluid dynamics concepts are introduced by considering the physical phenomena initially (IKO14) and then progressing to modeling (IKO15) them and carrying out simple calculations (in examples classes) through implementing the models (ISO9-11.

Assessment Rationale And Relationship

Semester 1 assessments:
The written examination will assess both the breadth of knowledge, written communication, literacy and ability to perform related calculations.
The coursework will assess acquisition of learning skills, initiative, numeracy, critical thinking and problem solving skills.

Semester 2 assessments:
Assessment of knowledge and understanding of concepts from qualitative exam questions ability to undertake necessary calculations from quantitative exam questions. Report of laboratory exercise assesses ability to apply theoretical knowledge in practical situation.

The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.

Semester 1 Study Abroad students would be required to sit an alternative examination in the December examination period.
