Maths assessment 1 in English and Arabic for grade 5

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

The learner will be able to demonstrate an understanding of:  Capacitance and capacitors as applied to electrical circuits.  The importance of magnetism in electrical circuits.  Inductance and inductors as applied to electrical circuits.  The theory and operation of DC. motors and generators.  AC. theory.  Voltage and current relationships for resistive, capacitive and inductive circuits.  The operation and uses of transformer and electrical filters.  The theory and operation of AC. motors and generators.  Apply the knowledge gained to practical tasks.

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

1 Data Representation Show understanding of binary magnitudes and the difference between binary prefixes and decimal prefixes Understand the difference between and use: •• kibi and kilo •• mebi and mega •• gibi and giga •• tebi and tera Show understanding of the basis of different number systems Use the binary, denary, hexadecimal number bases and Binary Coded Decimal (BCD) and one’s and two’s complement representation for binary numbers Convert an integer value from one number base / representation to another Perform binary addition and subtraction: Using positive and negative binary integers. Show understanding of how overflow can occur. Describe practical applications where Binary Coded Decimal (BCD) and Hexadecimal are used Show understanding of and be able to represent character data in its internal binary form, depending on the character set used Familiar with ASCII (American Standard Code for Information Interchange), extended ASCII and Unicode. Students will not be expected to memorise any particular character codes. Use and understand the terms: pixel, file header, image resolution, screen resolution, colour depth, bit depth Perform calculations to estimate the file size for a bitmap image Show understanding of the effects of changing elements of a bitmap image on the image quality and file size Show understanding of how data for a vector graphic are encoded: Use the terms: drawing object, property, drawing list. Justify the use of a bitmap image or a vector graphic for a given task. 2 Multimedia – Graphics and Sound. Show understanding of how sound is represented and encoded: Use the terms: sampling, sampling rate, sampling resolution, analogue and digital data Show understanding of how data for a bitmapped image are encoded. 3 Compression Show understanding of the need for and examples of the use of compression Show understanding of lossy and lossless compression and justify the use of a method in a given situation. Show understanding of how a text file, bitmap image, vector graphic and sound file can be compressed Including the use of run-length encoding (RLE)

Test with question and answer for year 6/7 and 8 -Geometric shapes using python programming turtle graphics

Describe the purpose of an operating system (You will be required to understand the purpose and function of an operating system and why it is needed. you will not be required to understand how operating system work.) Show understanding of the need for interrupts Show understanding of the basic Von Neumann model for a computer system and the stored program concept (program instructions and data are stored in main memory and instructions are fetched and executed one after another) Describe the stages of the fetch-execute cycle, including the use of registers and buses
