Newsflash:Woman found under WE forms on Mr O'D's desk
Categories: Advanced Higher, Coasts, Glaciation, s1 and s2The blog has taken something of a backseat lately, as I have been dealing with Work Experience and e-mentoring among other things. I am looking forward to having a little more time to put resources etc onto the pages, and have made a promise to myself to update the student blog, as detailed last week. I put an example of a pupil generated quiz from classtools on it today, and have more of these coming in along with the cultural geog tasks waiting to be uploaded. Please be patient, I'll get there...
On a more pressing note, more statistics for AH tomorrow. I feel, and hope that you managed to grasp sampling yesterday from our discussion. I was pleased that by using our example of finding out the favourite subject of a year group we managed to cover most of the points, here in summary:-
1) You could sample all the pupils-It would be representative, but time consuming and gave us an awful lot of data to handle
2) You could sample one class-but would 30 from 300 be a big enough sample? What if the results were affected by a particular teacher being popular/unpopular with that specific class?
3) You could take one pupil per class-but the sample would be far too small
4) You could take say three boys and three girls from each class, ensuring both genders were equally represented-but what if the year group ahd a larger number of males to females etc
Whatever way we looked at the sample, there was problems, and we also agreed that it would be easy to even unintentionally create bias in a sample. Afterwards, we decided there were various ways to sample information:- random sampling, systematic sampling and stratified sampling being discussed in a little detail, and this sets us up for some inferential statistics-where our findings will allow us to come to conclusions about certain statements called Hypotheses. I chanced upon a decent powerpoint when searching slideshare for 'Spearmans rank' - Here is the presentation link, thanks to prioryman. (I tried embedding this, but blogger didn't want to know...)
Meanwhile, with Higher, I have had to retread some old ground, which is fine-I had a look at the work and there was a huge variation in the quality of your notes on Glacial deposition, so we have been ironing out the creases on this, which will result in a little Lithosphere interim test on Wednesday. When we finally get back to coasts tomorrow in the first part of the double period, I was reminded by Miss Green of the Bawdsey Coast submission, an excellent example of the speed at which coasts can be eroded. There are a few other bits and pieces from a SAGT cd-rom, which again, I have nabbed from a colleague. There are also some very handy links for Higher if you visit the SAGT pages I've just linked to. s4 have been working on a newpaper style task looking at the impacts of the CAP, and will probably at some point use Old McDonald as a closer for this part of the course, an idea I think I saw first on Tony Cassidy's site, unfortunately still under construction otherwise I may have been able to use the excellent Henshaw farm audio resource. Some nice bingo for s1 a couple of periods ago and rattled through scale today-Grid refs and battleships on Thursday if I haven't posted again by then. Hopefully, next post will be much shorter and easier to find your way around, only two or three posts away from 200, another little landmark for the blog.
