Teaching Rationale And Relationship

Knowledge and understanding are acquired through lectures. The calculation classes will increase the ability of students to solve quantitative problems and carry out calculations in physical chemistry. Practicals are designed to reinforce the taught material and practice written, experimental, computer and problem solving skills. The drop in sessions allow discussion between module staff and students.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The examination and assessment are designed to test knowledge, numerical and problem solving skills.

The coursework provides continual practice in calculation.

Practical reports assess written, experimental, computer and problem solving skills.
