* Biological Sciences Dynamic Laboratory Techniques Manual (DLTM)


This ‘pre-lab’ resource, funded by the Higher Education Academy, (HEA) has been created with the help of academics and school teachers as an aid to students transferring from Post 16 education to first year undergraduate courses. The laboratory based skills of incoming first year undergraduates in the sciences in the UK HEIs is highly variable; some have had extensive practice in a wide range of practical skills and techniques whilst others have barely none. This software is designed to sit within an HEI’s virtual learning environment (VLE) and to be accessed by students prior to laboratory work. Students who have engaged with these activities should make better use of their laboratory time and reduce their demand on the lab demonstrators to teach the basics, thus allowing demonstrators to demonstrate at a higher level or to assess in ’more effectively.

The DLTM Resource

Each section gives a brief general introduction to the technique with images of equipment commonly used, sectioned video clips with notes giving hints tips and explanations, safety notes and finally a short multiple choice quiz. The quiz gives feedback to students’ answers so can be used formatively or summatively.

It should be noted that for some items of equipment, there are many variations. Not all equipment variations can be shown. The students having worked through the resource item should be able to apply their knowledge to equipment variations as well as to new situations.

The skills that are covered:

Weighing
Large volume liquids
Preparing solutions
Heating
pH meter
Centrifuge
Using a spectrophotometer
Preparing microbiological samples
Using a Microscope
Using Gilson pipettes
Creating serial dilutions
Sampling in the field

In addition there is an equipment glossary of common laboratory kit.

Navigation

Previous and next buttons allow each section of the resource to be navigated in order. A drop down menu allows the components of the resource to be investigated out of order. When a video sequence is being shown the controls at the bottom of the screen allow pause, forward and backward winding.
