Preparing students for repeat knowledge.

Discuss the topics and learning goals you will be repeating. 

3-10              min

Representative method

Students are divided into three groups.

The first group - "Nodes"

The second group - "Routers"

The third group - "Switches"

Groups discuss their topics. Their task is to identify the following characteristics of the network devices

Groups have posters. Students should collect information about their devices (description, functions).

One student from each group publishes their posts in the next group.

The groups should discuss the differences of devices and make a conclusion

Practical tasks

Task1

Four pieces of paper were found at the scene. The investigation found that they recorded fragments of one IP address. Criminologists have identified these pieces with the letters A, B, C and D.

Restore the IP address.

In the answer, specify the sequence of letters denoting the fragments in the order corresponding to the IP address.

Talk to students about how to get information about the Internet server

Task2

Conduct the following practical task. Start by opening the command prompt tool and type the following commands. nslookup is used to query the DNS server on Windows computers. Discuss the result in class

Examle:

Task3. Ask the students in the pair to discuss and explain the following scheme

Homework:

Task. You need to deploy a network with 40 computers. Which mask will you choose?

37-40 min

Reflection.

Students use Linoit online board stickers to answer the following questions.

- What were the problems?

- What have we learned today?

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

Assessment – how are you planning to check students’ learning?

Cross-curricular links
Health and safety check
ICT links
Values links

Observe SE throughout the lesson when moving around the classroom during group work.

Reflection

Were the lesson objectives/learning objectives realistic? What did the learners learn today? What was the learning atmosphere like? Did my planned differentiation work well? Did I stick to timings? What changes did I make from my plan and why?

Use the space below to reflect on your lesson. Answer the most relevant questions from the box on the left about your lesson.

Summary evaluation

What two things went really well (consider both teaching and learning)?

1: Questioning students, everybody involved

2: All students actively involved, lots of easy questions so more challenged students able to get involved.

What two things would have improved the lesson (consider both teaching and learning)?

1: Incorporate a game to find the information

What have I learned from this lesson about the class or individuals that will inform my next lesson?

Have a wide range of questions from easy to difficult for differentiation.
