FROM THE SECTIONS YOU STUDIED, WHAT, IF ANYTHING, DID YOU FIND DIFFICULT TO GRASP?
ANY FURTHER COMMENTS OR OBSERVATIONS
00191
Histology and function of the components of the ileum. Also how to relate dose to response.
Most things were straightforward
Choosing the correct axis for the graph. log 10 conc against response
00291
The basic action of neurotransmitters, how to set up experiments to show them in action and how to evaluate the results.
The action of neurotransmitters., the graph layout and the efficacy.
The equation to show how the sensitivity of the apparatus effected the results
Having had limited computer use I found the package easy to use and follow especially with the printed handout which accompanied the package.
00391
What agonists and antagonists are and how they act on tissue. Also the terms associated with drugs of this type.
I found all of it easy to grasp because it was presented in a clear cut manner using simple language and good use of diagrams
The computer package is a very user friendly package so users can concentrate on the context rather than how to use it.
00491
The effect of an agonist on muscle tissue when subjected to different lengths of time, and the theory behind it.
On the whole I found almost all of the package very easily understandable.
00581
A basic understanding of the experimental theory, setup and gain some insight into expected results and how to display them.
Experimental setup, agonist theory, agonist on Guinea Pig Ileum Receptors.
Comparing dose response curves
I found the package very useful and quite a good media from which to learn from. Not studying Biology at A level I was pleased to find that everything was explained adequately so my lack of knowledge in this area didn't effect me in any great way as I might have expected.
00681
How to set up the experiment showing effect of agonists on guinea pig ileum. How to construct dose-response curves. The variation in dose-response curves.
Construction of dose-response curves.
The theory of agonists
The package was very easy to use and was also enjoyable due to the diagrams. Although there were small tests included I think a larger test at the end might have been of more benefit, maybe not now, but when revision is commencing. The only confusion I had was when constructing the dose-response curves, as I think several lines of explanation - suggesting what values are most suitable - would have been of much more use.
00781
The action of agonists and antagonists on the guinea pig ileum and the experimental procedures use to investigate the efforts of agonists and antagonists.
The comparing of the dose-response curves.
00881
A basic intro to pharmacology and drug-receptor interactions. Just to get a feel for the subject and practicals ahead.
The experimental set up and practical sections were quite easy to grasp.
The theory of agonists was difficult at first, and some of the mathematics as well, but it was well explained.
I think the CAL package is an excellent way to study, so long as we can still do the wet practicals. The good thing about it is that we can go back and study in our own time after practical classes.
00981
The various responses of tissues subjected to different concentrations of drug.
The definitions were easy to learn, and the illustrated sequences. The graphs were also easy to understand.
Nothing.
I was able to work at my own pace, and so therefore take in the information easier.

The definitions of agonists and antagonists and the differences between dose and concentration.
Labelling of diagrams and calculating the amounts of Ach to add to give a dose/response curve with only 5 or 6 values.
01191

01681
The basic principles behind an agonist and dose response curves.
The dose -response curves
The maths calculations e.g. question 9 on questionnaire
I felt that the package was a success - especially when it came to explaining dose-response curves. The only difficulty I had with the package was understanding a couple of concentration questions - I did not think that this was explained very well since normally I have no problems having done some maths and chemistry at A level.
I liked the recap questions at the end of each topic - this enabled me to work through what I had learnt. Also the summaries were helpful.

02291
The requirements for setting up the experiments and a full explanation of the results of the effects of various drugs on the stimulation of the ileum.
Experimental setup and agonist theory
The other sections were time consuming in plotting the graphs but it wasn't too difficult
The computer package was very well designed in both the information contained and its set-out on the screen. but I felt that the `Agonists on the G.pig Ileum' was too repetitive of the previous sections.
02381

03691
Effects of agonists on tissue, and the formation and use of DR curves in pharmacology.
The interpretation of DR curves.
The initial theory. Too much information was included too soon which made it very hard to understand and remember.
A lecture may have been better to explain the beginning theory (e.g. questions 1 and 2 on test) I found all the information hard to take in when presented on the screen like that . Also time was a factor as we didn't have all day to work with it.

The maths related sections i.e. working out concentrations and logs and the experimental setup.
I enjoyed working through the package but there was so much to go through and it was quite boring. I don't really feel that I learned that much. I think I would have taken more in by having it explained to me in a lecture. I also think if we had worked in small groups I would have enjoyed and understood more.
06481
You were meant to learn the theory but it was also followed up by moving diagrams, which helps a lot.
The relationship between an agonist and antagonist
06591
I think that the package presented the experimental setup well and that allowed us to visualize the data well. I think the package provided us with a basic working knowledge.
The labelling of the ileum and the parts about Ka etc.
The maths part in working out the concentrations
I did enjoy working through the package of which I spent about 4 hours working through. I liked the visual illustrations and the labelling concept but I think that more time to work on it would have been useful.
06693
I think about how receptors in animal tissues as a whole respond to stimuli, the experimental details and interpretation of results and analysis.
I found the agonist theory very simplified together with the corresponding dose and concentration versus response curves fully described and definitions clear.
I did not find anything particularly difficult to grasp as there were very clear explanations given during the whole exercise.

Control of various parts of the ileum by different neurons, etc.
I don't think enough time was provided to work through the computer package at a speed at which it was easy to take in and understand all of the information given.

Definitions, dose response curves and most of the other sections .
Law of mass action and some of the equations.
I thought that it was a very good package and instructions on what to do were made clear. However, one or two of the diagrams which were shown in action so things were moving, were a bit too quick to watch very easily. I also thought that the test yourself sections were a good idea.
