Literature Review and Research Proposal

This unit involves an in-depth survey of the current literature relevant to the student's research project. Students will carry out an exhaustive search of the literature relevant to their project using the resources of the University, including appropriate databases and specialist search engines, as well as paper-based resources in the University Library. Based on primary research articles, review articles and textbooks, students will work independently under the supervision of the project supervisor to produce a document reporting on the background literature underpinning their research project. The literature review should demonstrate an ability to comprehend and synthesise the experimental evidence presented in the literature, to critically appraise previous studies and identify gaps in the knowledge, and to describe the experimental design of the research project.  To prepare their literature review,  students will meet at regular intervals with their supervisors to discuss their progress.

Advanced Scientific Skills

This module builds on existing, and further develops, generic scientific skills to equip postgraduate taught students with strong competences in presenting and reporting their research work using written and oral formats, in analysing data and the scientific literature, and in acquiring and extending their critical analysis skills. Teaching will be delivered using a blended approach with a combination of lectures, workshops, tutorials and seminars together with independent study and on-line teaching.

Taught throughout the academic year, the module will be articulated around three units addressing: 

Unit 1) Scientific presentation skills. In this unit, students will explore how to develop their academic (writing and oral) presentation skills. Some of the topics taught may include how to formulate a research question and hypothesis, how to find information, and how to structure a scientific essay or report. Students will learn how to communicate effectively their research to a scientific, as well as lay, audience. Emphasis will be placed on short oral communications and poster preparation and presentation.  The learning objectives will be acquired through lectures, workshops, tutorials and independent study.

Unit 2) Critical analysis skills. This unit prepares students to develop their ability to analyse and appraise the scientific value of the published and unpublished literature. Workshops and lectures will introduce students to the process of critical appraisal of scientific work. 

Unit 3) Statistics and data analysis skills. In this unit, students will learn methods to gather and analyse large datasets. In particular, workshops and lectures will teach students the basics of R coding and statistics for application in biosciences. The unit may also deliver other forms of data analysis relevant to the programme of study. Teaching within this unit will be delivered mainly through on-line material, lectures and workshops. Independent study will be essential to complete the acquisition of skills.

Critical Analysis of Current Science

This module is designed to develop the student's ability to read and understand the scientific literature relating to their own research area and also enable them to integrate their own work into the wider scientific field. The module consists of the following components; a seminar and seminar analysis programme designed to develop student skills in listening, understanding and appraising scientific research presented by external invited speakers; contribution, preparation and presentation of journal clubs reporting on the literature published in the field of biomedical science. In the latter component, students will be expected to demonstrate critical analysis skills, which will be encouraged through questions and discussions in classes. Each component is assessed through formal examination and oral presentation.
