[GCSE + IGCSE] Computer Science Trace Tables, Algorithms and Efficiency

[GCSE + IGCSE] Computer Science Trace Tables, Algorithms and Efficiency

This is an excellent resource that I have created and used with my Y10 and Y11 GCSE class (Y10 are IGCSE, and is relevant to both courses) I use this as a collaborative carousel activity where students in pairs (or however you want to work it) look at two algorithms at a time, tracing the values of the variables. This is a problem solving activity that should hopefully challenge students Computational Thinking, as well as revising their skills with Trace Tables and prediciting output of code, as well as spotting Logical errors. I have also used it to introduce the idea of preprocessing. This series of activities leads nicely into more challenging activities, such as sorting of data. When I teach this lesson, I use some theory resources and plenary activities, as well as some socrative quizzes over 3 lessons. Had a looking for learning observation whilst using these activities and feedback from observation was excellent. Having reviewed it with students, their feedback was (a long with the Data Strucutures activities uploaded and used prior to these activities) is that it really helped them to visualise how data is stored and manipulated in arrrays, as well as introducing preprocessing (which appeared in this year exam) as well as revising trace tables. Allowing the students to work in collaboration, discussing with one another and doing some peer review tied in neatly with some of the observational areas which we are looking at with ATL and Life After Levels. I was also toying with doing this as a group presentation activity, where the students can 'lead' this activity and 'be the teacher' explaining the inefficiences of their algorithm and how the data can be as issue also. This was also a perfect opportunity to revise why we use arrays in the first place - as I got students to re-write the code without arrays and it was a crazy series of IF statements, so plenty of scope to draw in other areas of the course.

Primary Computing - Understanding Pattern Recognition - Scratch Project

First, familiarise yourself with the terms Pattern Recognition and Decomposition, by watching Part 5 of “Delve in, for twelve min!” (Video linked above). Give the children the ‘Pattern Recognition’ scratch project. Children have to find different ways to reduce the amount of code that is repeated. I’ve included 3 different solutions; Broadcast (Not always the best solution, please see Part 6 of “Delve in, for twelve min!” on ‘concurrency and dependency’ ) Make a Block function (more advanced when you include number input) Using Make a block, selection and repetition (You can see how much smoother the code runs straight away) Please let me know how you get on!

KS3 Computational Thinking Project - Practical Problem Solving (Full Unit of Work)

KS3 Computational Thinking Project - Practical Problem Solving (Full Unit of Work)

**KS3 Computational Thinking Project - Practical Problem Solving (Full Unit of Work) ** This project is designed to either introduce computational thinking skills or to supplement and build on knowledge and skills already acquired. It is suggested that the student booklet is used in conjunction with the associated presentation through all of the lessons. The project has been designed so that is hands-on and practical. The suggested time frame from start to finish of the project is approximately 6-8 lessons, depending on what additional aspects the teacher wishes to introduce during the project. Students are asked to create a stationery holder using everyday objects. The problem has to be approached and solved using computational thinking skills. The project can be approached from a totally ‘unplugged’ pedagogy. No computers required! The resource consists of: a) A student booklet. This can be printed as an A4 or A5 booklet. b) A student booklet containing examplar responses. Also contains extension / homework tasks. c) A PowerPoint presentation for use in lessons to guide students and the teacher. Many of the slides have accompanying ‘speaker notes’ with ideas and suggestions for lessons.

OCR J276 Computer Science Paper 2 Revision - Knowledge Organisers

OCR J276 Computer Science Paper 2 Revision - Knowledge Organisers

The new OCR Computer Science 9-1 GCSE specification (J276) has a lot of new knowledge for the students to learn. I have created these knowledge organisers for my Year 11 Computer Science students. I have tried to make them as compact as possible - trying to fit the entire topic onto one side of A4 (two at most). The students used them for their Paper 2 mock exam in December. The feedback was really positive - they found them really helpful to recap the topic and have now also seen how they can be used to help answer the exam questions. As you can probably guess they have taken me many hours to put together and I have been improving them, and correcting them as I have been using them and working with the practice questions to make them as useful as possible. This is the first time I have sold anything on TES, I have found the new spec pretty daunting - so I do hope these can help a few people. Please do give me any feedback if you think there is anything missing and I will make any necessary changes. Thanks Rachel

tkinterTutor - learn how to develop fully functioning tkinter windows

I wrote tkinterTutor for my Python class who were struggling to get tkinter working properly. Whilst tkinter is an excellent GUI (Graphical User Interface) module for developing Windows-based screens in Python, it can be a bit finicky and time-consuming. tkinterTutor consists of a 37-page PDF document that demonstrates how to use common tkinter widgets, and 19 fully-functioning stand-alone tkinter programs. The PDF document links to the tkinter programs so that you can quickly open the programs and see how exactly to use each widget. tkinter’s geometry managers (pack, grid, and place) are also covered; how to use each one, when to each one, etc. Here’s the table of contents… Table of Contents Welcome to tkinterTutor 1 Introduction to tkinterTutor: 3 Basic Structure: 5 Frame with Label: 6 tkinter Widget Attributes: 8 Generic Fonts: 9 tkinter Geometry Managers: 10 The Pack Geometry Manager: 11 The Grid Geometry Manager: 12 The Place Geometry Manager: 14 Frame with Image: 15 Frame with Entry Widget: 17 Putting It All Together: 20 Fully Functioning tkinter Screen: 21 Menus and Sub-Menus: 22 Scrolling Text Box: 25 Screen Messages: 27 Message Widget: 28 Read a Text File: 30 Check Buttons: 31 Radio Button: 33 ComboBox: 34 LabelFrame: 35 Listbox: 36 Spinbox: 37 Sliding Bar: 38
