Title of Module: Evaluating Forensic Evidence

Code: CHEM08007 SCQF Level: 8
(Scottish Credit and Qualifications Framework)
Credit Points: 20 ECTS: 10
(European Credit Transfer Scheme)
School:School of Computing, Engineering and Physical Sciences
Module Co-ordinator:Alan   J.  Terry

Summary of Module

Students will learn how to measure the chance of events happening using probabilities and using odds. First, probabilities will be discussed: probability laws, conditional probabilities, independence, Bayes' theorem, and tree diagrams. Second, the approach of measuring chance using odds is considered, and students will see how a balanced view of the strength of the evidence in support of one hypothesis compared with another can be captured by the likelihood ratio.

The binomial and normal distributions will be introduced to assess the probability of different types of evidence occurring by chance.

An overview of genetics will be given so that DNA evidence can be assessed. The evaluation of DNA evidence at a crime scene will be discussed, with emphasis on the choice of a suitable reference population. The use of DNA evidence in paternity and missing persons cases will also be considered.

Additionally, this module provides an introduction to inferential statistics, looking at confidence intervals for a population mean and hypothesis testing.

The Crime Scene Investigation part of the module will look at the procedures used in CSI and the roles of the various staff involved in CSI. Using a variety of types of scene as context the content will include searching, recovering, analysing, and interpreting evidence. There is a laboratory component which will give practical experience of the various procedures followed during a scene examination.

This module will develop a range of graduate attributes, including numeracy skills, problem-solving skills, and the ability to present a clear argument.


Module Delivery Method
Face-To-FaceBlendedFully Online
check mark

Face-To-Face
Term used to describe the traditional classroom environment where the students and the lecturer meet synchronously in the same room for the whole provision.

Fully Online
Instruction that is solely delivered by web-based or internet-based technologies. This term is used to describe the previously used terms distance learning and e learning.

Blended
A mode of delivery of a module or a programme that involves online and face-to-face delivery of learning, teaching and assessment activities, student support and feedback. A programme may be considered “blended” if it includes a combination of face-to-face, online and blended modules. If an online programme has any compulsory face-to-face and campus elements it must be described as blended with clearly articulated delivery information to manage student expectations


Campus(es) for Module Delivery

Learning and Teaching
This module covers a wide variety of theoretical, conceptual and practical areas, which require a range of knowledge and skills to be displayed and exercised. Delivery of its syllabus content therefore involves a diversity of teaching and assessment methods suitable to the learning outcomes of the module; these include formal lectures, structured tutorials (work closely integrated with the lecture material),labs, completion and submission of written coursework making use of appropriate forms of IT and VLE, and independent study.
