Explaining a new topic

Each row in relational database tables must meet the requirement of uniqueness. Some fields can be repeated from record to record, but the combination of all fields of a line is found only once. If you do not follow this rule, then you can mistakenly attribute the properties of one object to another.

Let’s imagine there is a table with a list of students

The lines contain names of students who are full namesake, who study in the same group. This situation is unlikely, but possible. If one of these students does not pass the exams and expels him, then by mistake you can expel the other, who has no problems with academic performance.

To eliminate such errors, you will need to add an additional property that could potentially serve as an identifier: passport data, personal case number, etc.

Reflection

The learners speak in a circle with one sentence, choosing the beginning of a phrase from the reflective screen on the board:

today i found out ...

it was interesting…

it was difficult…

I was doing the job ...

I realized that ...

Now I can…

I felt that ...

I learned ... I did it ...

I could ...

I'll try…

I was surprised ...

The board

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?

Health and safety regulations

Additional support.

Work in pairs / groups - support for classmates.

Help the teacher, if required.

More capable learners can demonstrate aspects of their decisions that seem interesting / more complex to the other learners.

Assessment is carried out at each stage of the lesson:

- according to the assessment criteria, analyze the successes and difficulties that will allow the teacher to look at the lesson through the eyes of students, to analyze it in terms of value for each student.

Remind of some safety rules when working with computer equipment, for example, that you must be careful when installing the screen, keyboard and mouse; beware of wires, as they pose a threat to movement.
