A simple resource to help students remember how to convert from Hexadecimal into Decimal number (denary), and from Decimal number (denary) into Hexadecimal. As there are no calculators in the exam this year, it would help if students could refer to the 16 times table quickly when converting.

In final preparation for the GCSE Computer Science 9-1 exam, I have created some characters and simple tips to help students remember how to approach the different types of questions. If you can you this, and it can help students, please download. Good luck to all GCSE Computer Science students on 14 & 17 May 2018.

End of Unit test Differentiated questions on Dangers to computer networks, identifying vulnerabilities and preventing attacks. Teacher solution provided.

Preparation for the GCSE Computer Science 9-1 Paper 2. Reminders on how to do sorting, searching and data conversion. Student questions (differentiated - some with ‘methods’, some with additional pseudocode challenge) - Teacher solutions to main questions. DTT Revision - Key Areas: Data structures, errors, robustness and data types ( Therapy - as identified in mock exam).

Revision session - Focus: Calculation questions Storage capacity Converting between binary, denary and hexadecimal Binary shifts Binary addition Check digit calculations Questions & Solution provided.

Interleaving lesson - testing theory already taught and focusing on areas for further study: Independent questions: Data Representation/Truth tables Independent questions: Programming Techniques/Data Types DTT Revision: Flowchart symbols, languages, IDE and binary shifts Teacher-led question: Databases Teacher-led questions: SQL pseudocode

Each revision lesson gets the students working independently for the first part of the lesson, followed by a review of the answers. A specific area of Component 1 is then revised, and the lesson concludes with a QWC question. If you have longer lessons, you could add in past exam questions from the A451 syllabus which are related. Independent questions: Topologies, Network Protocols Teacher-led revision (and questions as part of discussion): Network Topologies, Protocols & Layers QWC question: Choice of network topology for a school.

Interleaving lesson - testing theory already taught and focusing on areas for further study: Independent questions: Data Representation/Truth tables Independent questions: Programming Techniques/Data Types DTT Revision: Units of measurement, bytes, character set and check digit Teacher-led question: Check digit OCR Guidance: Arrays -1D/2D arrays Teacher-led questions: Arrays

A specific area of Component 1 is then revised, and the lesson concludes with a QWC question. If you have longer lessons, you could add in past exam questions from the A451 syllabus which are related. Independent questions: Memory and Storage Teacher-led revision: ELCE QWC question: Technology today

Independent questions: Storage, wired/wireless networks and legislation Teacher-led revision: Legislation QWC question: Application of legislation.

Developed specifically for the GCSE Computer Science 9-1 Component 1 Exam. Based directly on the OCR Syllabus, it covers each element in bitesize chucks. A simple resource that can be used for independent revision, peer-to-peer Q&A and mix n’ match tasks. Golden Nugget Technique: Read a golden nugget. Read it again. Look away - what can you remember? Read it again - what did you forget? Read it again. Look away - have you remembered it yet? Repeat this process and learn the theory in little bitesize chunks Feedback from Parents Evening: “My child brought these home for revision. Even though I don’t understand the theory, I have the answers in front of me. I ask for a definition and compare his answers to those on the Golden Nugget. I can even give prompts because all the answers are there.”

Assessment on both Component 1 & Component 2 - on areas the Year 11 were struggling with. Marks out of 35 Solution and teacher mark grid provided.

In response to added emphasis on the Component 1 & Component 2 exams, following the NEA decision, I have re-structured my approach in lessons running up to the exams. Attached are two structured lessons which target specific 'question' styles at the beginning of the lessons, with revision of theory (based on OCR guidance - separate powerpoint theory on OCR website) before attempting a) for component 1, a QWC extended question or b) for component b, a writing algorithm questions. Over the coming weeks, as I develop the lessons to focus on areas of weakness shown in mock exams, I will upload further lessons in the hopes they can prepare your students for assessment as well.

Revision resource for students to revise the key topics of the Unit 1 Online world in preparation for the online test. Topics include: Online services, communication, software and documents; legislation; networks etc. How to use a Golden Nugget: Read a golden nugget. Read it again. Look away - what can you remember? Read it again - what did you forget? Read it again. Look away - have you remembered it yet?

A short check-test on Wired and Wireless networks. Teacher solution provided. An additional test of knowledge following mock exam weaknesses.

Integrate key programming skills for GCSE Computer Science 9-1 with a Christmas quiz in Python. Programming techniques: Iteration, selection, counter, functions, procedures, menus, lists, inputs and output. A bit of fun to end the term, whilst continuing to develop programming skills.
