[Year 12 SofDev] Question Re SAT need/opportunity

[Baas, Benjamin B]

If the students don’t have a need to use sort or search in the SAT could you not have them create a short example of sorting as another piece of work in class so you can still say they have done it and they can still get an  S for the outcome?

Why use sort when most languages have an inbuilt soft function? But that’s an argument for a different day.

Cheers,

Ben.

Hi all,

I have had students implement searching as part of interpreting algorithms and plan to do the same with sorting, but I still don’t see how we can mandate that students implement searching and sorting as part of a solution to the SAT. We certainly don’t demand that they use switch statements in preference to if:else statements or what loop structures they use.

It would almost seem silly demanding they maintain sorted data for most solutions given the size or complexity of program they will have time or skill to complete.

If they use XML documents or a database then sorting is not really necessary in many languages.

What if students use built in libraries to implement sorting? We don’t exclude them from using string functions and make them implement those themselves?

I have approached searching in terms of algorithmic complexity and have included it in one of the Unit 3 modules.

For Unit 3 SAT my interpretation was that students need to have completed algorithms as part of the detailed design so if sorting is in Unit 4 how can it be included in the design - no sorting means no binary searching.

If we do need to have students implement procedures such as sorting and searching as part of their SAT we need to be able to tell them before the end of Unit 3.

Regards

Brett

Thanks for this. My student is creating it in VB.Net<http://vb.net>.


I've pointed him to some tutorials so hopefully he can work it out.

Hi Mary,

Rendering pdf files inside an application will really depend on the environment the student is using. If the student has access to a web view object, something that can display html, it should be possible to display the file. The student may be able to leverage a control that opens the installed web browser on the target machine and uses that for the display, for example. Otherwise, if they can display a html page through some kind of html control, they might be able to utilise a javascript library like pdf.js to display the pdf. Finally, if they don’t have access to this, I suggest having the student look at pipelining the file to postscript and then to text/html as required. There are opensource tools available for this in the ghostscript libs and I am pretty sure they work on windows?! This will not work well for all pdfs but does work pretty well for text heavy documents.

Good luck,
Guy Flaherty

May be far easier to open the PDFs in other software and save as a text file...then read THIS file for his program.

Hi Mary

Do you mean the program searches the contents of a PDF?  Decoding a PDF file would be way beyond the scope of an SD SAC, IMO.

Or maybe a list of PDF filenames is searched for key words and a matching PDF file is loaded by the OS ... that would be achievable.

Otherwise, I'm unsure what the student's requirements are.

Cheers

Hi

I'd appreciate any feedback from you amazing teachers out there.

I have a student who has a need, this need is to read in a pdf document into his program, once a search has been performed the relevant pdf file will load in and display on screen.  Is this a viable project?  He will also create a form that allows his client to enter data when adding in a new report of incidents..

Sorry about the vagueness.  So he will have UI, programming logic, store of new reports and folder containing the pdf documents

Thanks in advance

Mary
