Assessment pattern

Alternative Assessment

Alternative assessment: Failure in the laboratory component may require reassessment through a defined practical examination.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

• Examination: Application of knowledge to important and archetypal organic chemistry explanations; extension of knowledge to a wider range of organic chemistry examples, with increased (relative to level 4) relevance to synthesis [LOs 1-3]


• Practicals: Ability to carry out typical organic chemistry reactions, and to interpret and analyse them in a manner appropriate to the discipline [LOs 1, 2, 4]

Thus, the summative assessment for this module consists of:

• Examination: closed book (80%, 1.5 h)


• Laboratory portfolio: Six stand-alone practicals with 6-7 h in the lab (20%, 42 h plus ca.10 h write-up

Formative assessment: The tutorials will be formative; comprising material designed to guide the student and give practice in the application of the lecture material to extended and unseen problems

Feedback: Formal feedback is provided on tutorial work, optionally on past exam papers and explicitly provided on all aspects of the practical work.

Module aims

• Build upon the basic organic chemistry in Level 4;
• Introduce more complex reactions and new mechanisms and concepts;
• Provide further training in, and practice of, common laboratory procedures on reactions covered in the lectures.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to facilitate assimilation of a large volume of information by emphasising the underlying mechanistic approach. The same approach is designed to allow application to unseen and more advanced cases. The practicals develop skill in more advanced techniques as well as reinforcing basic, but ubiquitous, ones. They also allow students to appreciate the relevance of the lecture material to the real-world chemistry environment.

The learning and teaching methods include:

• Formal lectures (25 hours)


• Practical sessions (42 hours)


• Formative tutorials (2 hours)


• General self-study (81 hours)

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
