At the start of every term I get many emails and phone calls from teachers who have recently taken over as the head of Computer Science and are unsure where to start. Some of them are walking into a well-ordered department where everything is laid out and ready-to-go, others are not so lucky. Often, they are the only person in that department and so don’t have anywhere to turn to ask for help. And then the headteacher casually strolls into your room when you have barely been for a day and asks you for your ICT policy document by the end of the week. Gulp! Not to worry, I have this one ready to go and better still it is completely free! With a brief read through, only some minor tweaking to make it fit your school and copying them into your schools template it should satisfy your headteacher and give you a bit of valuable breathing space while you try to get your head around the one hundred and one other things you need to do. School Data Protection Policy A School Data Protection policy isn’t really your responsibility as head of computer science and is something somebody who has received adequate training should be looking after. The name of the allocated data protection officer (DPO) and their contact details should be inserted into section 5.2 (Data protection officer) and is usually somebody in the admin team.

This can also be coped into your school template and requires staff to sign the last page.

Taking over a new year 10 GCSE computer science class? Wanting to find out your current classes Python programming skills? This resource contains a list of practical Python programming challenges which test key aspects of the KS3 national curriculum for text-based programming language. Pupils are tested on: Mathematical operators Data types Dealing with strings Loops If statements Logical operators Random numbers Data structures (lists) and Sub programs The pupils are given a worksheet which contains 11 Python programming challenges. They need to work through them attempting the programs and sections they can. If they don’t know how to do something then ask them to move on and try to complete as much of the challenges as they can. This allows you to find out the gaps in their current knowledge. The results are then entered into a an Excel spreadsheet using a simple system of 0 (not met the criteria) or 1 (met the criteria) that is then converted into a list showing you the pupils current understanding displayed as “Secure” or “Developing”. You can then use this to help you plan future lessons to fill the gaps in their skills. This practical assessment can be used at the end of Key Stage 3 to help you and pupils when selecting their options or it can be used at the start of their GCSE to assess which areas need to be recapped. This resource also includes the completed Python programs for all the challenges allowing you to see a possible answer for each challenge making this easier for non-specialists and NQTs who want to have a little more assistance as they build their confidence in Python programming.

This free document outlines the lessons that can be used to teach Python programming covering the national curriculum requirements for a text based programming language for key stage 3. It outlines the lessons and provides links to make your job easier when searching for a comprehensive, high-quality set of lessons. It also includes a link to an end of unit assessment.

This assessment test allows you to assess your pupils against the national curriculum specification for Python programming. It should be used at the end of Key Stage 3 as a summative assessment rather than as a formative assessment. The national curriculum specifies that by the end of Key stage 3 pupils should have been taught to “use two or more programming languages, at least one of which is textual, to solve a variety of computational problems; make appropriate use of data structures (for example, lists, tables or arrays); design and develop modular programs that use procedures or functions (for example, sub programs).” This test allows you to assess if your pupils have met this criteria. It includes a 6 page PDF document which should be printed and given to your pupils to complete under test conditions. There is no practical element to this test and is completed through a written test. This resource also includes a mark scheme to aid the teacher in marking the paper and even includes grade boundaries and descriptions that can assist the teacher when writing pupils’ long reports. Duration: 1 lesson This end of unit assessment does assume the pupils have been taught the following areas: Data types Syntax errors Logical and sequence errors Inputs and outputs Sequence, selection and iteration If…else statements Drawing and understanding flow diagrams Mathematical operators (+, -, * and /) Comparison operators (>, <, >=, <=, == and !=) For loops (count controlled loops) While loops (condition controlled loops) Simple lists and 2D lists (data structures) Sub programs Passing variables between sub programs and the main program Local and global variables FREE BONUS PRODUCT INCLUDED As a special thank you for purchasing this product I am pleased to be able to also include a surprise FREE bonus gift.
