1.1.2 Hexadecimal
•• represent positive numbers in hexadecimal notation
•• show understanding of the reasons for choosing hexadecimal notation to represent numbers
•• convert positive hexadecimal integers to and from denary (a maximum of four hexadecimal digits will be required)
•• convert positive hexadecimal integers to and from binary (a maximum of 16 bit binary numbers will be required)
•• represent numbers stored in registers and main memory as hexadecimal
•• identify current uses of hexadecimal numbers in computing, such as defining colours in Hypertext Markup Language (HTML), Media Access Control (MAC) addresses, assembly languages and machine code, debugging
1.1.3 Data storage
•• show understanding that sound (music), pictures, video, text and numbers are stored in different formats
•• identify and describe methods of error detection and correction, such as parity checks, check digits, checksums and Automatic Repeat reQuests (ARQ)
•• show understanding of the concept of Musical Instrument Digital Interface (MIDI) files, JPEG files, MP3 and MP4 files
•• show understanding of the principles of data compression (lossless and lossy) applied to music/video, photos and text files
For all Teacher attached a student project for you attention:
Please before you solve any pre-release material for students. It is better to let them try to solve it first.
please give this project to your student for a period of a month therefore you can measure students progress and attainment.
IGCSE Pre- release material for Computer Science paper 2 - Student Project
Attached the Pre-release material for paper 2 exams , Please ask the students to open the PDF and watch the video and it will give students a starting point how to solve task 1/2/3 for this year exam. Thank you
But before that. student should start attempting pre-release paper 2 for last year May/June 2021, Please ask the student to go straight to slide 11 and do the last year exam paper 2 May/June 2021 , Students will find the questions/answers and the python programming code for task 1 / 2 and 3 .
I included python programming code for last year paper 2 exams for task 1/2/3 . Please make sure students practice using last year exam paper 2 before they start solving this year paper 2 . Thank you
Ask the students to solve and provide the following three tasks for this year exam:
pseudo code and python programming for Task 1
pseudo code and python programming for Task 2
pseudo code and python programming for Task 3
E-learning can be defined as the use of computer and Internet technologies to deliver a broad array of solutions to enable learning and improve performance.
E-Learningg has become an important part of our educational system and has changed the way we view teaching as a whole.
E-Learning in today generation has developed and improve the core aspects of teaching and has made schools perform more efficiently or more productively and quickly.
Students will experience various iPad Apps by introducing flavors of the Computer Science subjects including graphic design, web design, iBook creation, Animation and Movie creation. This part of the course will help learners address their own interests and match them with their particular intelligences that need to be developed using the following application:
• Keynote App
• Book Creator App
• Pages App
• iMovie App
• Animation Studio app
• HTML Studio App
Notes Plus allows users to create annotations and type text easily and more accurately on their device. Better and more functional, Notes Plus features note-taking tools plus other features that users might want for all their note- taking needs. Notes Plus lets users create fine text notes simply by utilizing their fingers.
Now, on to the review of my favorite features of Notes Plus:
Below, I took a screenshot of the portrait layout of Notes Plus, imported the screenshot, and annotated it in Notes Plus to show the features and tools available. The layout is simple and intuitive, easily customizable.
Please feel free to leave a review. Thank you
