1. PGCE Computer Science/ICT Progression in Databases Alex Hadwen-Bennett

2. Learning Objectives You should understand the content that needs to be delivered in the area of databases at KS3, KS4 and KS5. You should be able to identify key terms and concepts in this topics. You should start to understand progression in this topic. You should gain some awareness of the resources that can be used to teach this topic in school.

3. Agenda Session 1 What do students need to know about networking at each KS? Activity: Progression in databases Session 2 Unplugged activities for databases

4. KS3 National Curriculum Undertake creative projects that involve selecting, using and combining multiple applications, preferably across a range of devices, to achieve challenging goals, including collecting and analysing data and meeting the needs of known users. There are no specific references to databases, however their use is implied in this statement:

5. Progression Pathways Databases are referenced throughout the progression pathways.

9. Databases Unplugged Cut out the table and stick it in the middle of your A4 sheet. Cut out the entities and group them to form records for each game. Stick the entities in the correct place on the table. Turn your A4 sheet into a revision poster by: Adding “Databases” as the title. Labelling the primary key and writing a short definition of the term. Labelling a record and writing a short definition of the term. Labelling the table the writing a short definition of the term.
