ANALYSIS AND INTERPRETATION OF BIOLOGICAL AND ANCIENT EVIDENCE - 2020/1

Module code: CHE3055

Module Overview

The purpose of this module is to give students a more detailed knowledge of aspects of forensic chemistry. The chemistry relating to DNA, fingerprints, toxicology and forensic archaeology is dealt with in detail. Casework examples are used to give students a broad understanding of how data is interpreted. This module interacts with material that students are taught through analytical chemistry modules and demonstrates the application of relevant techniques to forensic casework.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate achievement of the learning outcomes.

Thus, the summative assessment for this module consists of:

• Examination – 1.5 hours

• Coursework – DNA multi choice test

Formative assessment

Test questions during exam tutorial

Feedback

Discussion sessions; practice exam questions

Module aims

  • • examine the scope and background of forensic investigation of body fluids and other biological material
  • • give a detailed account of techniques used in advanced biomedical analysis
  • • introduce the student to techniques used to identify historical artefacts and materials
  • • outline the scope of forensic toxicology

Learning outcomes

Attributes Developed Ref

Overall student workload

Independent Study Hours: 121

Lecture Hours: 22

Seminar Hours: 6

Tutorial Hours: 1

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

provide students with an up to date understanding of current forensic chemistry practices by seminars given by expert guest lecturers

provide students with a detailed understanding of and a critical appreciation for biological evidence and its chemical analysis through lectures, casework examples, videos and discussions.

The learning and teaching methods include:

• Lectures (22 total)

• Seminar (6 hours)

• Exam tutorial

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.
