EBU4201 Introductory Java Programming 2024/25
Mini-Project

Introduction

Submission on QMPlus must be done by ONE of the group members by the deadline indicated under the “Mini-Project Submission” task. See page 12 for details of the submission requirements.

Assessment will consist of two parts, i.e. group submission made on QMPlus and individual student performance during the mini-viva. Details of marking criteria will be provided separately.

Feedback forms will be provided with a breakdown of marks and comments.

Specification

We are QMUL London School, home to over 500 children aged between 5 and 10 years, enrolled in Key Stage 1 (Years 1–2) and Key Stage 2 (Years 3–4). Due to the large class sizes, it becomes challenging to provide individualised attention. Therefore, we are seeking your assistance in designing a user-friendly Graphical User Interface (GUI) based application called “Shapeville” that can act as a teaching assistant, helping children learn and practise basic geometry.

Inclusivity and accessibility: our population includes 14 children who are colourblind, so it is essential that the design is inclusive and accessible to support their needs. Inaddition, some children have short attention spans, therefore the application should be able to maintain engagement and motivation.

Following a thorough requirement analysis, a list of core features has been identified which must be included at a minimum in the final application as listed below.

Shapeville Introduction

a) Information about the available game levels.

b) A “progress bar” to help users track their advancement during the session.

c) A button labelled “End session” - when the user clicks on this button, anappropriate message with the current score/progress must be displayed beforegracefully terminating the application. E.g. “You have achieved 21 points in this  session. Goodbye!”.

A button labelled “Home” should facilitate the user to return to the above screen at any time.

Key Stage (KS)1:

Children will engage in two core tasks:

Key Stage (KS) 2:

Children will work through two core tasks, along with two bonus challenges:

Bonus Tasks:

Scoring and Feedback:

An appropriate message, e.g. “Great job!” must also be displayed every time points are awarded.Mini-Project: Shapeville

Task 1: Identification of Shapes

Figure 1 and Figure 2 provide a list of essential 2D and 3D shapes respectively.

For each sub-task (i.e. 2D and 3D), the application should function as follows:

Figure 1: Basic 2D Shapes for Identification Task

Task 2: Identification of Angle Types

Figure 3: Types of Angles

Task 3: Area Calculation of Shapes

• Allow the user to select one of the four shapes.
• The application generates random numbers (1 to 20) for the appropriate input values (e.g. length and width for a rectangle) and displays them on the screen.
• The user has 3 minutes to calculate the area and enter their answer.
• Once the user enters the correct answer or uses up 3 unsuccessful attempts, the application should display the shape with labelled dimensions (e.g., length, width, height etc.) directly on the diagram, along with the formula and substituted values (see Figure 4).
• Process continues until the user has practised all 4 shapes OR clicks on the “Home” button.

Task 4: Area and Circumference Calculation of Circle

To help users learn better, the application should provide a guided and interactive experience of area/circumference calculations. An overview of the relevant formulas and methods is shown in Figure 5 (Area and Circumference based on Radius) and Figure 6 (Area and Circumference based on Diameter).

Bonus 1: Compound Shapes Area Calculation

The methods for calculating the area of compound shapes are illustrated in Figure 7, Figure 8, and Figure 9.

Mini-Project – Submission Requirements

a) Allocation of tasks to each member of the group (1 page).

b) Design of the system including flow charts and class diagrams (2-4 pages).

c) Justification of your design choices, e.g. why were certain buttons or layouts chosen, how does your design help users complete the tasks easily paying attention to inclusivity and accessibility requirements (1/2 page – 1 page).

d) User-manual for your application (1-2 pages).

e) Description of the utilisation of AI and other tools which must include details of which specific tools have been used in which part of the Mini-Project (1-2 pages). THREE key prompts submitted to AI tools and related responses must be provided in the Appendix in a clearly organised manner, including a brief note on whether those responses were used as they were or modified by you. See Note-1 below for details.

f) Reflection on your experience of the Mini-Project, as a group (1/2 a page). This must be an account of your genuine view, including what you think went well and not so well, how you might improve things if you were to do this project again etc. AI tools must NOT be used for this task.

2) All Java source files (with appropriate internal comments).

3) HTML javadocs.
