Luck & Hard Work!

I wish my students the best of the first, but it has to go hand in hand with a great deal of the second part of the above title. When in doubt, use your common sense –  and remember to write complete and sensible answers. See you after the exams!

Notes & annotated Spreadsheet

I’m aware that students have a textbook for content guidance, but I’ve also uploaded sets of notes to the blog. Notes are to be found to the bottom right of this entry. I have uploaded an annotated version of the Spreadsheet example. Although your version should NOT be annotated, the annotations are to ensure that you have included everything the exam board expects on this asignment. This is to be found to the left of this blog entry, the first document under ‘Guidance’.

Checking Unit 1 Spreadsheet Project

WJEC have produced an updated (26.03.09) Teachers’ Guide for AS and A Level.  I’ve lifted out part of the the section clarifying the spreadsheet work from Unit 1:

The context for the task in 2009/2010 is ‘business modelling’.  Care must be taken to ensure an appropriately demanding task is undertaken which addresses the features listed below.

Candidates will be given credit when providing practical evidence from their task to support their answers in the written examination. Candidates should produce a spreadsheet workbook which contains evidence of;

• worksheets showing labels, data, formula

• multiple sheets and the use of 3D referencing between them

• lookup or vlookup or hlookup tables

                drop down list boxes

                spinners for data entry

                logical True or False or Tick Boxes or Option boxes

• startup user interface

• validation techniques and error messages produced

• sorting techniques

• Search for specific criteria

• Control buttons should be used to initiate macros.

• Appropriate use of graphs such as bar or column graphs, line graphs, pie charts, scatter graphs, pictographs

Candidates should be familiar with the following formulas / standard functions:

A

B

SUM
COUNT
MAX
MIN
AVERAGE
RAND
SINGLE IF
MULTIPLE IF
DATE
ROUND

and should include evidence of at least two formulas or standard functions from list A and two from list B in their workbook.

Simulation Modelling

 Candidates should understand and be able to discuss the following;

• Definition of a simulation model.

• Uses of simulation modelling for weather forecasting, car crash analysis and financial forecasting.

• Advantages and disadvantages of using simulation models.

• Issues relating to hardware used for simulation modelling, including parallel and distributed processing.

Page 15 of the Teachers Guidance focuses on the type of questions which could be asked of the Spreadsheet Modelling task and Pages 16 – 22 shows an example of the evidence students should produce.  Today in class, we are going to look at this exemplar and check off all the elements which your completed projects should include.
