J277 1.2.4-1.2.5 · Data representation
Includes J277 1.2.4 Characters and text
How text is stored in binary, covering character sets, ASCII, Unicode and text-file size. Students will: - explain what a character set is - explain how characters are represented in binary - relate bits per character to the number of available codes - compare ASCII and Unicode - calculate the size of a simple text file Inside: 6 explanation cells, 4 multiple-choice questions, 1 fill-in-the-blanks cell and 5 written answers. 27 marks, about 60 minutes. Series: J277 1.2.4-1.2.5 · Data representation, part 1 of 5.
WorksheetSeries · 3 partsJ277 2.1.1-2.1.2 · Computational thinking and algorithms
Includes J277 2.1.1 Computational thinking
The opening Paper 2 worksheet, introducing abstraction, decomposition and algorithmic thinking as problem-solving approaches. Students will: - identify each of the three approaches - use each one in a new situation - explain how each helps define or refine a solution - distinguish an approach from a Python feature - justify the approach chosen for a problem Inside: 4 explanation cells, 1 runnable Python task, 2 multiple-choice questions, 1 fill-in-the-blanks cell and 4 written answers. 19 marks, about 45 minutes. Series: J277 2.1.1-2.1.2 · Computational thinking and algorithms, part 1 of 3.
WorksheetSeries · 2 partsJ277 2.4 · Boolean logic
Includes J277 2.4.1 Boolean operators and truth tables
The first Boolean logic worksheet for OCR J277 2.4.1, covering the three required operators and the truth tables that describe them. Students will: - state what a Boolean value is and where a computer uses one - describe what AND, OR and NOT each do to their inputs - recognise the symbol for each of the three required gates - complete a truth table for a single operator - apply the operators to a stated real condition Inside: 4 explanation cells, 3 multiple-choice questions, 1 fill-in-the-blanks cell and 2 written answers. 11 marks, about 45 minutes. Series: J277 2.4 · Boolean logic, part 1 of 4.
WorksheetSeries · 2 partsJ277 2.2.3 · Applied programming
Includes J277 2.2.3 Two-dimensional arrays and records
Two-dimensional arrays and records, the two structures OCR uses for grids and for entities. Students will: - create a two-dimensional structure and access it by row and column - update a value at a given grid position - process every value with nested loops - represent one entity as a record with named fields - choose between a grid and a record for a requirement Inside: 6 explanation cells, 4 runnable Python tasks, 2 multiple-choice questions, 1 fill-in-the-blanks cell and 2 written answers. 23 marks, about 60 minutes. Series: J277 2.2.3 · Applied programming, part 1 of 5.
