1. Part A: Employability Skills

Communication skills · Self-management skills · ICT skills · Entrepreneurial skills · Green skills

Communication Skills: How to Share Meaning Clearly and Kindly – Communication is sharing meaning between people. A sender encodes an idea into a message, sends it through a channel, and a receiver decodes it and gives feedback. Barriers such as noise, hard words, strong emotions and cultural differences can block or bend the message. We send meaning with words (verbal), with face, eyes, gestures, posture and tone (non-verbal), and with pictures (visual). Active listening — attention, patience, questions and paraphrasing — proves the message arrived. Good communicators adapt to context: formal or informal, spoken or written, and use polite requests, kind refusals, sincere apologies and assertive (not aggressive or passive) language.
Self-Management: Taking Charge of Your Feelings, Goals and Time – Self-management is the skill of guiding your own feelings, thoughts and actions so you can reach your goals. It starts with self-awareness: noticing what you feel and how strong it is. Then you pause before reacting (Stop, Think, Act) and use calming tools such as slow breathing. Your beliefs and thoughts shape your feelings and actions, so changing an unhelpful thought ('I'm useless') into a helpful one ('I can't do it yet') changes what you do. Good self-managers set SMART goals, plan their time by importance, build healthy habits and bounce back from setbacks (resilience). These skills help in school, friendships and future careers.
ICT Skills: Office Tools, Internet, E-mail and Staying Safe – ICT means Information and Communication Technology. It is the set of tools we use to make, store and share information: computers, phones, software and the internet. The core ICT skills are: using a word processor to write, a spreadsheet to calculate, a presentation tool to show ideas, the internet to search, e-mail to communicate, and good habits to stay safe online.
Entrepreneurship Development – Entrepreneurship is starting a new business by spotting a need, putting resources together and taking the risk. India needs entrepreneurs for jobs, new ideas and balanced growth. The process runs from knowing yourself to launching and growing. Start-up India (2016) supports new firms, funding comes from savings, angels, venture capital, banks and crowdfunding, and intellectual property rights protect new ideas, brands and creative work.
Green Skills: Sustainable Development, Green Economy and Green Jobs – Green skills are the knowledge, habits and job skills that help us live and work without harming the planet. They rest on sustainable development (meeting today's needs while leaving enough for the future). A green economy grows while cutting pollution and waste, often by going circular: make, use, repair, recycle. It creates green jobs such as solar technician or recycling worker. Everyone can use green skills through the 5 Rs: Refuse, Reduce, Reuse, Repair, Recycle.

2. Publication and Communication Design

Design Thinking: Solving Problems by Starting with People – Design thinking is a way to solve problems by first understanding the people who have them. It has five stages: empathise (watch and listen to users, using tools like an empathy map), define (write a clear problem as a 'How might we…?' question), ideate (create many ideas, including from nature: biomimicry), prototype (make quick, cheap models) and test (try them with users and improve). It is iterative and user-centred, and it opens up and narrows down twice, like a double diamond.

3. Moving Images

Moving images

Animation: How Still Pictures Start to Move – Animation is a row of still pictures (frames) shown quickly one after another. The eye and brain join them, so we see motion. Frame rate (fps) says how many frames are shown each second: more fps = smoother motion. Key frames hold the main poses; in-betweens fill the gaps (tweening). Main types: hand-drawn (frame by frame), stop motion (paper cut-outs, clay), 2D computer, 3D computer. Raster animation stores pixels; vector animation stores shapes as maths, so it scales without blur.

4. Information Design

Information design

Presentation of Data: Tables, Bar and Pie Diagrams, Histogram, Polygon, Ogive and Line Graphs – Data can be presented in words (textual), in tables (tabular) or in pictures (diagrams and graphs). A table has a title, captions, stubs, body and source. Bar diagrams compare values; pie diagrams show parts of a whole with angle = value ÷ total × 360°. For frequency distributions we draw a histogram, a frequency polygon, a frequency curve and ogives. Time series data is shown with an arithmetic line graph.

5. Product Design

Product design

The Design Process: From Problem to Product – The design process is a loop of steps designers use to solve a real problem for real people: investigate the need, define it in a brief and a measurable specification, generate many ideas, build a prototype, then test and evaluate it against the specification. Whatever fails sends you back round the loop. This repeating is called iteration, and it is how almost every product, app, building and artwork is improved.

6. Interface Design

Interface design

UI and UX Design: Making Screens Easy and Pleasant to Use – Interface design is planning the screens people use on phones, computers, ATMs and machines. UI (user interface) is what you see and touch: buttons, icons, text, colours and layout. UX (user experience) is how the whole task feels: quick or slow, clear or confusing. Good interfaces put important things first (hierarchy), keep buttons big enough to tap (about 9 mm or 48 px), use strong colour contrast, stay consistent, give feedback after every action and need few steps. Designers study users, draw wireframes, build clickable prototypes and test them with real people, then improve.

7. Game and Toy Design

Game and toy design

Game and Toy Design: How Play Is Planned, Tested and Improved – Game and toy design is planning things people play with so that play is fun, fair and safe. Play can be physical, building, pretend, puzzle or social. A game has players, a goal, rules, a challenge and a way to win or end; a toy has no fixed rules but invites open play. Good design balances challenge and skill so play is neither boring nor frustrating, and gives choices and feedback. Designers make quick, cheap prototypes (paper, card, clay), playtest them with real players, watch what happens, change one thing and test again. Toys must also suit the age group and be safe: no small parts for young children, smooth edges, safe materials.
