Key Stage 3 National Strategy Handling data: session 2

© Crown copyright 2002 KS3 Strategy Slide 2.1 Objectives for session 2 By the end of this session you will: be clear about what pupils should be taught about graphical representation of data, including fitness for purpose be aware of a range of appropriate teaching and learning strategies

© Crown copyright 2002 KS3 Strategy Slide 2.4 Issues to be addressed in ICT 1Can pupils use the software to create a graph or chart? 2Is the graph or chart appropriate for the data? 3Is the graph or chart ‘fit for purpose’?

© Crown copyright 2002 KS3 Strategy Slide 2.5 Graphical representation in ICT themes Finding things out: reading a graph, testing a hypothesis and drawing conclusions from frequency or scatter graphs Developing ideas and making things happen: transforming, developing or displaying information in various ways to understand it better and communicate it more effectively to others Exchanging and sharing information: considering fitness for purpose and reviewing, modifying and evaluating work as it progresses

© Crown copyright 2002 KS3 Strategy Slide 2.6 By Y6, most pupils should be able to: identify the information needed to solve a simple problem collect relevant data classify information for use in a database and understand how a suitable structure is created recognise different data types, e.g. text, numbers enter data into a database, search it and present data in simple tables and graphs check that information is accurate and reasonable, and predict what might happen if data are entered incorrectly

© Crown copyright 2002 KS3 Strategy Slide 2.15 Starter YES/NO cards This involved: an active and interactive starter activity that can be used in a wide range of different contexts questioning of the whole group to ascertain levels of understanding ‘whole-class’ discussion, including asking for justifications of viewpoints

© Crown copyright 2002 KS3 Strategy Slide 2.16 Main activity Data handling in ICT, mathematics and science This involved: explanation by the tutor of cross-curricular overlap paired reading and discussion to consider less familiar material a summary of three issues to be noted

© Crown copyright 2002 KS3 Strategy Slide 2.17 Main activity What should be taught in Year 7 This involved: teaching input a reminder of points from a previous lesson practical demonstration of the skills involved in a process

© Crown copyright 2002 KS3 Strategy Slide 2.18 Main activity Considering ‘fitness for purpose’ This involved: paired discussion and an open-ended practical task (positioning cards on a grid, another activity that can be used in a range of contexts) feedback on particular examples, with comments invited from pairs who made different decisions

© Crown copyright 2002 KS3 Strategy Slide 2.19 Plenary Summing up This involved: revisiting the objectives involving the ‘class’ by asking individuals to say what was important about the session, then asking others to agree or disagree a summary of the key learning points covered in the lesson
