What you need

Unit 4 Outcome 2 – The task

Outcome 2: Interactions and impact

On completion of this unit the student should be able to analyse and explain the

dependencies between two information systems and evaluate the controls in place

in one information system to protect the integrity of its source data.

Task type:

In response to a case study, one of the following:

• a written report

• an annotated visual report.

Unit 4 Outcome 2

The purpose of this task is for students to produce a written report or an

annotated visual report in response to a case study.

The case study should provide details about:

• the interactions between information systems that share data

• the dependence on data integrity for one of the information systems

• data management practices in the storage

• communication and the disposal of data

• capabilities of the information systems in a networked environment and the

application of protocols when interacting with these information systems.

The case study

What teachers need to let students write about

When writing the case study, teachers should consider how it will enable

students to write about:

• the existing network environment

• interactions between information systems

• identifying the causes of conflict

• evaluating data management practices

• how legislation affects data management practices

• characteristics of data integrity and the impact of diminished data integrity on

the organisation

• how the organisation secures data and information

• evaluating how the information systems objectives are being met.

Writing the case study

Findings from Stage 3 and 4 Audit

• Majority of submitted tasks were commercially prepared ones

• All the submitted tasks, including the non-commercial tasks, required

revision

• Teachers experienced difficulty in writing appropriate case studies and

using prompts that were not overly detailed

• Several tasks referred to proposed information systems and lacked

sufficient details. This made it difficult for students to adequately

prepare a written report.

• It is recommended that the case study include existing information

systems that have sufficient detail to enable students to meet

requirements

Findings

Report format

• Many teachers stated that their students would be completing a written

report

• Often the written report was a series of questions or detailed

prompts/statements with mark allocations – not features of a written

report

• There were instances of an ‘exam style’ format outcomes with multiple

choice, short answer and case study questions – does not meet the

study design requirements.

The written report

Report format

• Appropriate prompts can be included for students to assist them in

writing the report; however, students should not be provided with

questions or detailed prompts that could be considered undue

assistance.

• For example, students could be directed to write a report that considers

the following areas:

• types of networks

• nature of security measures

• data interdependencies, etc.

Written report format

• The majority of the submitted tasks used the VCAA performance

descriptors for decision-making about assessment

• Some users of the commercial tasks chose to use commercially

developed marking guides

• A variety of marking schemes were used by teachers

• Outcome 2 is to be marked out of 100

• Submitted tasks varied with total scores out of 20, 30, 40, 67 and 100

• Marks for questions or prompts varied from one mark to 20 marks

• Some marking schemes were awkward and made differentiation

between student performance difficult as there was limited opportunity

for partial credit

• Marking schemes should be suitable for the task given with whole

marks awarded for responses

Assessment of case study

• Teachers are encouraged to become familiar with the relevant VCAA

course documentation including the study design, particularly the key

knowledge and the advice for teachers

• It is important to plan, deliver and assess content with these documents

in mind

• Students should also be given copies of these documents at the

commencement of the course

• While many teachers thought they were giving their students an

acceptable case study and prompts for them to write a written report, it

was apparent many teachers did not understand what should be

expected in a case study

• It is recommended that teachers make an effort to write their own case

studies following the appropriate VCAA documentation with suitable

prompts and marks allocated

Final comments

Purpose:

• Ensure assessment is conducted in line with VCAA principles of

assessment and requirements of the Study design using appropriately

designed tasks

• Because quality issues can arise, the audit process can help to identify

and address these

Stage 3: Online Questionnaire

• Collect information on the planned approach to assessment and

assessment practice – teachers need to refer to Study Design

• If OK then response is: Submission meets requirements

• If concerns, maybe not enough details, then response is: Further

evidence is required

• If serious concerns then response is: Submission requires immediate

follow-up

School-based Audit

• Based on the questions answered in questionnaire – Audit Panel

determine if details given indicate whether requirements are being met

or not

• If any doubt – Audit Panel will recommend Further Evidence at

Stage 4

School-based Audit

Stage 4: Further Evidence

• Submit further evidence based on online submission in Stage 3

• May be because of an aspect of assessment, information provided,

marking schemes, etc.

• If OK the response is: Further evidence meets requirements

• If concerns then response is: Further evidence may not meet

requirements and then resubmission or maybe on to Stage 1 (2018)

• Some teachers go to Stage 4 because their Online Questionnaire may

not be clear, may lack detail, provide incorrect details, etc.

• Sometimes looking at the task gives a good idea of what is going on

• Commercial tasks can be a concern and this can be seen at this stage

School-based Audit

Unit 4 Outcome 2

What is required to prepare students to write a report?

Unit 4 Outcome 2

VCAA Descriptors

Developing an approach to

writing a case study

• This will take a while to write, but it is worthwhile

• Need to start at the beginning

• Ask the question – What are your students working towards?

• When planning the assessment you could start with the VCAA

descriptors

• Ask the question – What do students need to cover in their report?

• You could match the Key Knowledge to the descriptors

• Think of appropriate prompts to assist students in writing their

report

• Write the case study to include the details that are needed for

students to write the report
