ASSESSMENT OF CANDIDATES IN COMPUTER SCIENCE SYLLABUS (4021)

This circular brings to your attention procedures for the assessment of Ordinary Level Computer

Science (4021) candidates.

1. The Practical Coursework

Candidates will be expected to present a project. The expectations of the project were sent
out in 2017 (see Appendix 1) and copies will be kept at Regional Offices for centres to

photocopy if they find that to be more convenient.

A contents page should be prepared to indicate the location of sections of the project. The
candidate’s project should contain the individual assessment mark sheet (See Appendix 2)

with all the teacher’s marks indicated.

The project document should contain the project assessment form (See A ppendix 3) with all
candidates’ marks recorded. In addition, the teacher should submit a soft copy of the
candidates’ work in the form of a CD. Each candidate should have a folder on the CD, where
his/her project has been saved. The folder should have the candidate’s name and number.

The project should be completed by 05 October 2018 and the projects should be
submitted to ZIMSEC Regional Offices or ZIMSEC Cluster Collection Centres by 26

October 2018.

2. The Practical Examination

Each registered candidate will sit for a practical examination as indicated in the syllabus. The
duration of the Practical Examination is 3 hours. Please note that the 3 hours does not include

Directors; Prof E. (Eddie) Mwenje (Chairperson), Mrs M.F Masiye — Moyo (Vice-Chairperson), Mr W.C Chanakira, Prof M. Furusa,
DrC.A.T Katsvanga, Ms F. Mokwena, Mr W.T Mufuka, MrA.M Mukuvisi, Mr F. Mhlanga, Mr N. Nhapi, Prof L.M Nyagura, Mrs L. Ross,

Ms B. Sigauke, Prof D.J Simbi, Prof K. Wekwete, Mr E.S Nhandara (Executive)

printing time. Therefore, candidates will be allowed to print their work after 3 hours of writing.

In the case where the number of candidates exceeds the number of computers/machines the
centre has, the centre will be allowed to have two sessions. A maximum of 1 hour is
allowable for the change over to the second session. The Computer Science teacher and other
invigilators should make sure that all the machines have been cleared of documents before
the second group starts writing. The two sessions would require that the Computer Science
teacher creates candidate accounts for them to log in and save their documents.

Each candidate will be expected to submit a hard copy and a soft copy on CD. The CD
should bear the School Name, Candidate Name and the full Candidate Number. Candidates
should not use passwords on CDs.

2.1 Preparations Before the Practical Examination

Heads of Centres should make sure that adequate preparations have been made for the
practical examination. Preparations should include the following:
e Servicing of machines

e Ordering enough stationery; bond paper and printer cartridges
e Ordering enough CDs

e Having a standby power source e.g generator

e Clearing machines of saved documents

e Creating candidate accounts in the case of two sessions

e Removing papers on the walls of the computer laboratory

e Cleaning the laboratory in general.

2.2 During the Examination
There is need for thorough supervision when the examination is written. The Computer
Science teacher should be available for consultation but not in the examination room.
Other invigilators will supervise the candidates as usual.

2.3 After the Examination
After the examination, candidates should be allowed to print their work. Printing time is
outside the 3 hours. Candidates should tie their printouts together and submit both the
hard copy and soft copy. The work is treated as examination material and should
therefore be submitted in the normal way as the other scripts.

PROJECT GUIDE 2018

The learner is required to develop a computer-based project to solve a specific problem using a
high level programming language for example Visual Basic or Python. The project is to be
carried out from Form 3 end of Term 2 up to Form 4 Term 2. This will enable the learners to use
their skills and experience gained during the course to analyse, design, implement, test and
evaluate the solution to a problem. Learners are advised to document every activity undertaken
as they carry out the project.

The mark a candidate achieves is linked to the problem definition. Guidance from the teacher is
needed in the choice of a problem. Teachers must provide on-going support, guidance and
supervision while learners carry out the project.

Project Guide

The project must include the following layout

1. Cover page
2. Table of contents
3. Appendices
e Sample of completed questionnaires
e Sample of interview questions with respondent answers
e Sample documents
SECTIONA
Selection, Investigation and Analysis

e Problem Definition/Identification

e Investigation of the current system
