4.1. Create a design brief to develop a webpage focusing on accessibility and usability features.

4.2. Decompose the problem of appealing to a target audience by analysing how colour, font-size, layout and content can be used effectively in a web page design.

5.1. designing the user interface of a solution using a range of design tools

5.1.1. for example using a storyboard to explain the stages of a game, and wire-frames and mock-ups to describe the appearance of a solution

5.2. identifying similar digital systems and their user interfaces, assessing whether user interface elements can be re-used

5.2.1. Identify the common elements on webpages from the same site and creating a template for these components.

5.3. applying the principles and elements of design to a series of solutions to evaluate the success of each solution to hold the viewer’s attention

5.3.1. for example identifying which colour combinations or framing of visual elements keep different audiences engaged with on-screen activity

5.4. Create a range of website mockups based on a client brief and use client feedback to evaluate the strengths and weaknesses of each mockup.

5.4.1. Eg. Each group member creates a website mockup and only one mockup is selected for the final website.

6. 8.7 Design algorithms represented diagrammatically and in English, and trace algorithms to predict output for a given input and to identify errors (ACTDIP029)

6.1. investigating and designing some common algorithms

6.1.1. such as to search, sequence, sort, merge, control data structures

6.2. checking the accuracy of an algorithm before it is implemented

6.2.1. for example desk checking it with test data to see if the instructions produce the expected results

6.3. using diagrams to describe key decisions

6.3.1. for example creating flowcharts using digital systems to describe a set of computational instructions

6.4. using structured English to express algorithmic instructions

6.4.1. for example using conventional statements such as ‘while’ and ‘endwhile’ in a ‘while loop’ when describing interactive instruction

7. 8.8 Implement and modify programs with user interfaces involving branching, iteration and functions in a general-purpose programming language (ACTDIP030)

7.1. Create a simple web form with data validation.

8. 8.11 Plan and manage projects, including tasks, time and other resources required, considering safety and sustainability (ACTIP033)

8.1. organising the instructions and files in readiness for implementation of a solution

8.1.1. for example applying a file naming convention to all data files that are going to be used to create solutions

8.2. documenting the tasks that need to be done, their order and the resources that are needed to create solutions

8.3. devising and applying protocols to manage the collaborative creation of solutions

8.3.1. for example planning to use cloud computing to store common files and establishing virtual meetings that acknowledge time zone differences

8.4. organising the timeline, resources, file naming conventions, back-up measures and sequence of tasks required to collaboratively create solutions that meet specified needs

9. 8.3 Acquire data from a range of sources and evaluate authenticity, accuracy and timeliness (ACTDIP025)

9.1. designing a search engine query to find specific information on the web and checking its accuracy against information contained in other sources
