22 Examination Issues ‘New specification’ allowance
Some evidence of well-prepared candidates The majority of candidates at GCE ICT levels There are serious concerns about the overall performance

23 Examination Issues Candidates must use appropriate DT terminology
Candidates must know definitions ‘The program counter contains the address of the next instruction to be fetched/executed.’ AS Q4ai

24 Examination Issues Candidates must address the question
Key word, mark allocation ‘Identify four principles specified in the Data Protection Act.’ [1] SAM A21 ‘Describe the main features of the physical layer.’ [3] ‘Using SQL, produce a query which …….’ [3] ‘Explain how each of the following can be used to keep data secure:’ ‘Compare and contrast A with B’ [4] Context ‘Using examples from this database, explain the following terms:’ ‘Describe how each of the following can be used to detect data transmission errors.’ [4] Reference: GCE ICT Microsite  Support Materials  Exemplification of Standards PP & PDF (2009)

25 Examination Issues AO3 & Quality of written communication Mark scheme
‘A large organisation decides to use a third party to host their payroll system. Evaluate the organisation’s decision with respect to security.’ [9] SAM A21 Mark scheme Indicative content What is hosting, how is it implemented, security issues Banded responses Band B2 Excellent [7] - [9] Band B1 Good [4] - [6] Band B0 Basic [1] - [3]

26 Examination Issues

27 Finally, the challenges
The Revising Team Specification approved  The Examining Team Valid, accurate and consistent assessment within a series, from one series to the next Teachers Prepare candidates CCEA Support SAM, Factfiles, Microsite, Exemplification, Chief Examiner’s Reports

28 4.5 Synoptic assessment at A2 4.7 Reporting and grading
The A2 assessment units include some synoptic assessment, which encourages candidates to develop their understanding of the subject as a whole. In our GCE Digital Technology, synoptic assessment involves: building on material from the AS units; bringing together and making connections between areas of knowledge and skills that they have explored throughout the course; following their own lines of enquiry, and recording and observing from primary sources; and responding to one or more of the following: a stimulus or scenario; a design brief or problem; and/or a task that requires them to produce a specific image, object or other outcome. 4.7 Reporting and grading We report the results of individual assessment units on a uniform mark scale that reflects the assessment weighting of each unit. We award AS qualifications on a five grade scale from A to E, with A being the highest. We award A level qualifications on a six grade scale from A* to E, with A* being the highest. To determine candidates’ grades, we add the uniform marks obtained in individual assessment units. To be awarded an A*, candidates need to achieve a grade A on their full A level qualification and at least 90 percent of the maximum uniform marks available for the A2 units. If candidates fail to attain a grade E, we report their results as unclassified (U).

31 7.5 Internal standardisation
7.4 Marking the tasks Teachers should use their professional judgement to apply the criteria in the mark bands appropriately and fairly to candidates’ work. They should take a ‘best fit’ approach to award the appropriate mark within a range, balancing strengths and weaknesses in each response. For up-to-date advice on plagiarism, or any kind of candidate malpractice, see Suspected Malpractice in Examinations and Assessments: Policies and Procedures on the Joint Council for Qualifications website at 7.5 Internal standardisation Centres with more than one teaching group must carry out internal standardisation of their internal assessment tasks before submitting their marks to us. This is to ensure, as far as possible, that each teacher has applied the assessment criteria consistently. It may be necessary to adjust an individual teacher’s marking: to bring it into line with that of other teachers in the centre; and to match the standards established at the agreement trial. If marks do change, centres must amend the total/final marks on their Candidate Record Sheets.

34 Instructions for Conducting Coursework

35 GCE Digital Technology: Preparing Samples for Moderation
for A2 2 Application Development It is the responsibility of all centres to present GCE Digital Technology samples in an appropriate manner to enable CCEA to carry out the moderation process efficiently and effectively. Work can be submitted on CD or USB. Ensure that all candidates in the sample have removed all unnecessary files from their folders in preparation for moderation. Please check to ensure that the solution and the portfolio of evidence files can be opened from the media used.

36 CCEA A Level Digital Technology
A Application Development Case Study Gerard Lynch Principal Moderator

37 Overview Opportunity to apply skills and knowledge
Use Digital Technology to solve problems Document a solution

38 Moderation 2018 Submission will be electronic
Date for submission will be the end of April Moderation procedures for the majority of Centres will be similar to the legacy ICT specification CCEA will request all the work from a small number of random centres after submission of marks to meet Ofqual procedures The weighting of the coursework is 20% of the A Level grade Legacy specification was 40%!

39 Presentation of Coursework
Each Candidate should have a separate folder Folder is clearly labelled with candidate number Indicate the highest and lowest Candidate Storage medium is clearly Labelled with Centre Details

40 Presentation of Coursework
Each folder contains clearly labelled documents Each Candidate should submit two documents The documentation should include clearly labelled subsections as outlined in the specification The database solution should allow access to all components

41 Time Management Content Weighting ( Raw Marks)
Time Allocation ( Hours) Analysis 30 15 Design Application Development Documentation and Evaluation Total 120 60

42 Expected Outcomes Centres should consider the raw marks awarded to a solution in line with the grade outcomes using uniform marks( out of 120) A* 108 A 96 B 84 C 72 D 60 E 50

43 Challenges and Opportunities
All Candidates will use the same problem/scenario Each candidate will define the scope of their solution Candidates will have to carry out research to establish their user requirements Centres will need to differentiate between their candidates to ensure there is a range of marks Solutions should reflect the Candidates ability to solve problems

44 AS Content Required Approaches to System Development
Reasons for systems development Analysis Design, Development and Testing Implementation Data and Information Data, information and knowledge Data Validation/Verification Hardware and Software Application Software Input/output devices used in applications

45 A2 Content Required Databases Features of a relational database

The main sections of the organisation include: Customer Services – Creating and maintaining customer details Accounts Department – Creating and maintaining invoices and payments Sales and Order Processing – Creating and maintaining sales and orders Shipments – Organising deliveries to customers Products – Creating and maintaining a range of products in stock Suppliers – Creating and maintaining supplier details

47 Analysing the problem Produce a Gantt chart to schedule the project
Identify internal and external constraints that may impact on the solution Detail the user requirements in terms of inputs, processes and outputs Prioritise and justify user requirements into essential and non-essential Use analysis tools such as DFDs (level 0 and level 1) to illustrate the flow of data through the information system and the processes required Specify the hardware and software requirements to produce the new system.

48 Focus on Analysis Gantt Chart – Include detail on how the 60 hours is to be used on solution etc. Constraints – Hardware, software, personnel, budget, time, legal issues etc. User requirements – Outputs expected, inputs including data capture, essential v’s non essential, solution may not include non-essential etc. Use analysis tools such as DFD ( level 0/1) to identify processes, data flows etc. Hardware and software specification

49 Designing an appropriate solution
Produce an overall design for the system Produce a description for each process, and algorithms where appropriate, based on user requirements Produce a detailed design of each user interface, including appropriate validation Use data modelling techniques to produce an ER diagram for a fully relational database Show in detail how the database solution is normalised to 3NF Design the required queries and reports Develop a comprehensive test plan

50 Focus on Design Overall design may include:
Structured diagrams, storyboards, algorithms etc. Interfaces may include forms, buttons, switchboards etc. ( screenshots of forms etc. will not be accepted as design components) Data structures may include tables, validation etc. ER modelling and Database normalisation to 3NF etc. Use of other database tools - Queries, reports, macros etc. Include SQL and/or QBE Test plan including test data, reference to use requirements, expected outcomes etc.

51 Application Development
Select and use appropriate software to develop and implement the solution Test the software solution Document a strategy for system implementation

52 Focus on Application Development
Solution should reflect Design Include the working solution No requirement to include screenshots for every test Results should cross reference to test plan with brief commentary Corrective action should be documented Implementation plan may include data conversion, changeover method etc.

53 Documentation and Evaluation
Evaluate the solution against the user requirements Identify possible extensions to the system Develop an electronic guide, accessible from the user interface that explains how to use the application

54 Focus on Documentation and Evaluation
Evaluation include reference to user requirements both essential and non-essential, limitations, strengths, future developments etc User documentation may include a link from the solution, user guide, FAQ’s etc.
