INTRODUCTION
Introduction
This advice and guidance provides an exemplar project and suggested
learning and teaching approaches that may give learners the opportunity to
carry out, research and gain understanding of computer systems and hardware
technology.
The suggested learning and teaching approaches and materials could be used
as guidance and may be applied to a number of areas within the Computer
Science course. This suggested learning and teaching approach could support
learners in developing an understanding of key principles and will allow them
to carry out meaningful research in order to gain a deeper understanding of
contemporary systems and hardware. Learners will also gain experience and
confidence in comparing and evaluating hardware technology and be given a
chance to demonstrate this knowledge.
The exemplar project structure allows learners to demonstrate their
understanding through a number of collaborative tasks and the development
of a contemporary solution. This contextualisation means that the project
could be used to reinforce previous skills and give learner s a number of ways
to develop and demonstrate progression on their journey towards a secure
understanding of the Computing Science course. The project will be learner
driven and should allow flexibility with a focus on active learning approaches
and opportunities for learners to identify their own areas of interest and carry
out appropriate research into hardware and develop their own solution to the
project brief.

EXEMPLAR PROJECT DESCRIPTION
Exemplar project description
Learning and teaching approaches
The aim of this exemplar project is to allow learners to gain knowledge of
contemporary hardware technology, understand their features and how to
compare and evaluate some of these features , and gain an insight into
emerging technologies. The emphasis is on learner-led research so learners
should have enough flexibility to allow them to identify requirements and
develop a solution that is relevant to their own experience or interests . The
starting point for this exemplar project is the use of technology from the point
of view and experience of the learner, looking at the current applications of
technology as well as new and emerging technologies. The key areas should
highlight what the learners are required to focus on in their research in order
to gain the information that will be required for the product they will design
and create. Learners should gain an understanding of contemporary and
emerging technology, a range of hardware devices and the way these devices
fit into their modern lives.
In this exemplar project the areas of focus will be the learners’ research into
and comparison of hardware technology. The identification and choice of
hardware types can be driven by the learners’ experience and research into
the current trends and future developments. This can be used as an
opportunity to reinforce good research technique, resource evaluation and
online safety as learners will have already been exposed to these concepts.
At each stage of research learners will gain an un derstanding of the key areas
and could be introduced to and apply a number of skills, such as planning and
communication. Research and development could be carried out in small
development teams, encouraging collaboration, the sharing of tasks and high level thinking skills. There is also the opportunity to transfer a sha red
responsibility for learning through team development , and the allocation of
roles within each team and collaborative working encourages a more active
approach by the learners.
The exemplar project brief asks for the development of short technology
reviews in the form of videos or animations delivered via a website. These
videos or animations should make use of the research into current and
emerging technology products as well as being informed by any research into

EXEMPLAR PROJECT DESCRIPTION
current trends, future trends, user needs and comparison criteria. The site
containing the videos or animations could be delivered in the form of a small
stand-alone website, but would perhaps provide a better, more realistic
learning context when delivered as an integrated part of a larger website that
may be created in the information systems development unit. The form the
final piece of work takes may also be determined by the learner’s prior
experience.
This advice can be used as a starting point for the development of the
exemplar project to promote problem-solving skills and reinforce the
learners’ understanding of all the stages involved in the development of a
web-based solution and the required video content.

Peer evaluation and testing throughout
development followed by ‘live’ testing
Blogging could also be used as a diary
throughout the project and used in the
evaluation of performance for each
group
The blog location could also allow the
presentation and promotion of the
completed project to gain feedback from
a wider audience, including parents

Slide 1
Introduction to some of the key questions raised through this project.
The idea of being a ‘smart buyer’ could be introduced at this stage , as could
the outline of the project brief if this is appropriate.

Slide 2
Explore technology use within the class.
Conduct a poll to find out what types of computer devices people own or have
access to and which they use most frequently.
Ask learners to add a tally to the Venn diagram to illustrate ownership and
use. This could be done using an interactive whiteboard or a flipchart.

Slide 3
Discuss modern survey techniques.
Ask learners to create a short survey using an online survey tool to gather
information from their friends and family, eg surveymonkey.com,
kwiksurveys.com.

Slide 4
In groups of four look at what is popular based on some survey results.
Do big numbers, eg fastest processors, most memory, biggest screens,
connectivity, cool factor, physical size, and battery life, lead to popular
devices?
Identify and list what is actually important to buyers. What does the smart
buyer buy?
The ‘superlist’ of important specifications from all groups can be placed on
the classroom wall and can be added to if anyone identifies additional
important criteria.

Slide 5
Learners pair up and each chooses a smartphone or tablet (this would also
work well for consoles, eg PS3 vs Xbox 360, or any other piece of
technology) and carries out some research into its important specifications.
Which device is ‘better’ or has the highest specification?
Should ease of use be added to the list of categories? What about portability?
This task could also be presented as a TopTrumps style game.

Slide 6
Create a class ‘coolwall’ and add pieces of technology and hardware on the
left if they are cool, on the right if they are uncool and higher up if they are
considered to be quality pieces of technology by the class.
This can be an ongoing process even past this project to encourage awareness
of technology and constant re-evaluation of existing products.
Technology sites such as www.TED.com, TechCrunch.com, AllThingsD.com,
Mashable.com, www.CNET.co.uk and www.bbc.co.uk/click could provide
some resources.

EXEMPLAR LEARNING AND TEACHING APPROACHES
Slide 7
Learners should analyse the problem and create a brief storyboard, plan or
script for their videos. A good starting point may be to look at published
examples on review sites such as those mentioned in the slide and BBC click
etc. They could be encouraged to look at the ‘superlist’ on the wall of the
classroom generated by the previous task.
Additional research will be required to gain the knowledge of the system the
teams are reviewing, although if at all possible some time to actually use the
current device being reviewed should be allowed, for example time to test an
iPad. Access to emerging technology will be more difficult so animations of
still images and video sourced online could be used.
Depending on the video-editing experience of the learners they may require
support but the assumption is that they will have had at least s ome exposure
to video-recording equipment and editing software to allow them to produce a
video clip that is in a format suitable for publishing on a website and fits the
time restraint. There is opportunity to talk about file formats, compression
and storage requirements.
Development teams could be chosen to include mixed abilities and
experiences, and a project manager could be identified (in a fixed
appointment or on a rolling basis throughout the project) to take
responsibility for progress and bloggin g the team’s progress.

Slide 8
www.webpagesthatsuck.com and www.w3schools.com may be of some help
here to support existing skills in web development. This is a good opportunity
to discuss standards online (w3c etc) and the development of different
platforms for maximum exposure.
FTP and FTP clients could be introduced here and their suitability, ease of
use etc.

Slide 9
Peer evaluation of the sites produced. If possible the learners could be given
the opportunity to upload their solution to a server to allow them to fully test
links and compatibility issues.
In addition to testing within the establishment the sites could be added as the
final post to the ongoing project blog with a self -evaluation of the final
product, an evaluation of the team’s success and a summary of the knowledge
gained.
