1.9 计算课程的课程主线

In this step you will begin to explore the primary Teach Computing Curriculum (TCC) in more depth. This provides a useful framework for a high-level view of computing that will help you to build your subject knowledge.

There are four main strands in the Teach Computing Curriculum, each taught in all year groups from age 5 to 11. For each year group, the curriculum contains:

• One unit in the ‘Computing systems and networks’ strand
• Two units in the ‘Programming’ strand
• Two units in the ‘Creating media’ strand

• One unit in the ‘Data and information’ strand

  计算机系统和网络

  This strand begins by explaining what a computer is. It also explores how networks can be used to retrieve and share information, and the associated risks that come with this. Learners begin by exploring what technology and information technology (IT) are, and then move onto exploring networks and the internet. Finally, they investigate how computing systems and networks help people communicate and collaborate.
  The key concepts to understand in this strand are:

• How to identify examples of IT

• How to use IT responsibly to help people
• Digital devices feature inputs, processes, and outputs
• Digital devices can be connected in networks, and the internet is a network of networks

• How to collaborate and communicate online

  编程

  This strand looks at designing, creating, and evaluating algorithms and creating programs to allow computers to solve problems. In this strand, teachers introduce learners to a range of platforms, designing and making games and quizzes suitable for all year groups, and work towards controlling physical devices with computers.
  The key concepts to understand in this strand are:

• Commands can be combined in programs

• Sequences can be used in programs
• Parts of programs can be repeated
• Programs can flow in different ways, depending on conditions being met or not

• Something that changes (for example, a score) is controlled by a variable

  多媒体技术（创造媒体）

  In this strand, learners select and create a range of media, including text, images, sounds, and video. Learners begin by creating simple digital painting and writing, then in later year groups they combine media to create videos, podcasts, and 3D images.
  The key concepts to understand in this strand are:

• Computers can be used to create a wide range of media

• Information can be stored and retrieved
• Media can be modified and edited
• Different media can be combined

• Content is owned, and there are rules around when and how it can be used

  数据和信息

  In this strand, learners investigate how data is stored, organised, and used to represent real-world artefacts and scenarios. They use a variety of different technologies to present data in graphs, spreadsheets, and databases, and also perform an investigation using a data logger.
  The key concepts to understand in this strand are:

• Data can be collected and presented

• Questions can be created and answered with data
• Data can be captured to carry out investigations
• Data can be organised and compared

  Make a copy of this action plan either by downloading it to your computer, or by making a copy on Google Drive. You will continue to fill this in throughout the course.
  In the following two weeks of this course, these main strands will be explored in more detail. Based on the descriptions above, rate your subject knowledge confidence for each of the four main strands, using a RAG (red, amber, green) scale, with red being the least confident and green the most confident.
