Module 4: Computer Science

 

The final Pick ‘n’ Mix module was all about computer science. Many of my previous blogs give information regarding the topics discussed within this module and they are linked below:

Unplugged:

Algorithms can also be taught using the unplugged concept. Children complete challenges which relate to that of an algorithm, for example, children describe to a partner how to complete simple daily tasks such as getting from one place to another, making a jam sandwich or even tying your shoelaces. Whilst explaining, children will have time to adjust and amend their instructions or debug them, creating problem solvers and computational thinkers.  Computing unplugged can be adapted for use in many lesson such as DT, English, Maths and PE.unplugged cs

Computer Science Unplugged offer some great activities to use within the classroom to help introduce and develop computational thinking.

KS1:

KS1 computer science is a little different to KS2 as they learn to:

  • Write and test simple programs
  • Manipulate data
  • Organise data

Below are some useful resources to use with the children when teaching and learning about the areas outlined above:

Write and test simple programs: understand algorithms and how they are implemented as programs on digital devices

Manipulate data: manipulating and retrieving data in a range of digital formats

Organise data: organising and classifying whilst working creatively using digital media

KS2:

KS2 has significantly more computer science aspects and these can be read about in detail on my KS2 National Curriculum blog.

Areas addressed within the module include (some are linked up to previous blog posts):

  • Analysing and presenting
  • Computer Networks
  • Control
  • De-bugging
  • Decomposition
  • Discernment
  • How an algorithm/program works
  • Programming
  • Repetition
  • Variables

Below are some useful resources to use with the children when teaching and learning about the areas outlined above:

Analyse and Present: use and combine a variety of software to analyse and present data and information

  • Google Trends – great way for children to explore and compare data series. Links nicely with Google Flu Trends
  • Piktochart: create your own infographics combining global and local data by adding images, text and data to ready-made themes. Alternatives are easel.ly and infogr.am. A successful Year 3 student project
  • worksheet to use with children in order to teach them the difference between random data and data organised in a table.  They initially attempt to answer impossible questions based on random data – they can only really guess the answers.  They turn over and answer the same questions once the data has been organised into a data table
  • Hackasaurus: mash up and change any web page like magic. Use ‘x-ray goggles’ to hover over a website to see behind the scenes, then remix, make and share webpages or create your own, all within your browser. This makes it easy for children to tinker and mess around with the building blocks that make up the web. Includes resources for teaching webmaking: printables, cheat sheets, lesson plans, assessment rubrics, and a slideshow.
  • Popcorn Maker from Mozilla makes it easy to enhance, remix and share web video. Combine video and audio with text, links, maps, pictures and live feeds to make your own interactive newscasts, pop-up videos, multimedia reports, fan videos, guided web tours and more. Remix your favorite videos on YouTube or sounds on SoundCloud, add your own comments and links, or drag and drop in content from across the web.The result is a whole new way to tell stories on the web.
  • Mozilla Thimble: Thimble projects are hackable webpages that allow you to complete a challenge, play a game or build something cool by editing the code of the page, and learn webmaking skills like HTML and CSS in the process. Beginners can tinker around with template projects such as ‘Build your own Awesome Animal’, ‘Make an Animated Avatar’ or ‘Make Your Own Meme.’ Or you can hack into a pre-made game, customise it and share with friends
  • Text2Mindmap: A simple way to organise and classify information and show it visually. Outline your ideas as a list of topics and subtopics and an animated mindmap is automatically generated. You can drag and bounce your mindmap around the screen, edit fonts, colours and lines, rearrange the layout and save as a .jpg. Provides a quick focus on the hierarchical relationships between topics

Decomposition: solve problems by decomposing them into smaller parts

  • Before pupils create something in Scratch it can be useful to look at a working example and decompose what is happening. Spider Game on the Scratch website is here. Use right and left arrows to steer the spider. Spider Game planning is here.
  • Children (yrs 4-6) begin by working in small groups to develop a dance routine and record it on a flip cam. They break down the dance routine into parts and develop flow charts for each part.Pupils then edit screen gabs of them in different dance positions, whilst performing dance routine then import into Scratch costumes. Finally pupils use Selection and repetition to reconstruct the dance routine in scratch.
  • Thinking Myself: Computational Thinking in K-12 A peek into computational thinking through a series of lessons and games for children in grades K-12 defining the terms decompose, patterns, abstraction, algorithms and variables through examples and interactions

Discernment; Not believing everything that is read online

  • All About Explorers: what looks like a regular history site is full of inaccuracies. Activities are designed to help children learn to check facts and apply critical thinking skills to their research.

Repetition: 

These are largely a collection of downloadable PDF’s that you can use with Microsoft’s LOGO program.  Children’s activities on this sort of application are often enriched and enhanced by working in pairs due to the opportunities for developing mathematical language and reasoning.

Variables: 

  • Scratch Maths Quiz which uses a single variable to hold the score. This is increased if the user answers questions right and is reported to the user after each question. (Yrs 4 & 5)
  • Scratch Automated Maths Quiz This builds on the concepts explored in Maths Quiz. The numbers are generated randomly and stored in two variables. The two variables are multiplied and the result stored in another variable. The user answer is compared to total variable. (Y5)
  • Text Based adventure game in Scratch Main Planning Variables used for hitpoints help sheet
  • Python Code (Adapting a poem) This module looks at the creation and use of a variable within a poem. The variable can be created by the programmer or by the program user or selected randomly from a list of items. (Yr 6) I think it is easier to explain variables with Python than Scratch but Python needs MUCH teacher training time investment!
  • Creating a shape calculator in Scratch where the number of repetitions is dependent on the number of sides on a shape.
    Thinking Myself: Computational Thinking in K-12 A peek into computational thinking through a series of lessons and games for children in grades K-12 defining the terms decompose, patterns, abstraction, algorithms and variables through examples and interactions.
