TOPICS IN FORENSIC SCIENCE - 2018/9

Module code: CHE3051

Module Overview

The purpose of this module is to give students a detailed knowledge of forensic chemistry. In this third year module, 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

The assessment strategy is designed to assess whether students meet the learning outcomes of the module.

Thus, the summative assessment for this module consists of:


Examination – 1.5 hours
DNA In class test


 

Formative assessment

Test questions during exam tutorial

 

Feedback

Discussion sessions; practise exam questions

Module aims

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

Learning outcomes

Attributes Developed
001 Give a critical account of the theory and practice of various techniques used in a biomedical laboratory
002 Provide evidence of a detailed knowledge of the chemistry of body fluids and the value of evidence gathered from such specimens
003 Critically evaluate the value of evidence gathered from archaeological sites
004 Evaluate methods used to detect drugs and poisons and review the role played by forensic toxicology in forensic investigation

Attributes Developed

C - Cognitive/analytical

K - Subject knowledge

T - Transferable skills

P - Professional/Practical skills

Overall student workload

Lecture Hours: 21

Seminar Hours: 6

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.
