Assessment.

For the performance of all tasks on the Internet resource gaining max 8 points

Teacher’saction:

To control the time of students ' assignments and give feedback

ІV. Group work

Students are divided into 4 groups by pictures

Solving problems using the "Station" method.

There will be four stops in total. At each stop there are level tasks.

Student action:

Students together with their group stop at each stop and solve the given tasks.

Task descriptors:

·         Correctly write the given condition of the problem.Translation to SI units

·         To write using formulas

·         Correctly write the answer and ways to solve the problem

Teacher’saction:to control of accurate performance and correct assessment of tasks by each group. Give feedback.

Assessment

For each correct offset is assigned 3 points. In total, the overall group work is max 12 points. Groups evaluate each other.

VI. Home work 8,3-8,4

From problem solvers: №3,58-3,66

VII. Reflection

«2 stars and 1 wish.» 

Students write on the sticker that they realized that they did not understand. Counts the number of points scored during the lesson, and analyze their scores.

distributing material

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

All students know: the concept of electric field strength and electric field lines.

can characterize the movement of the charge in the electric field.

Can distinguish between homogeneous and heterogeneous fields. The principle of superposition can be used in solving problems. Can solve level a problems.

Some students may write by heart all the definitions for academic language. Able to explain and analyze the power characteristics of the electric field.

Can solve problems at the B-C level.

Evaluation of each other in independent work

Points scored in pair work with the task of the Internet resource

Evaluating each other in a group in group work

At the end of the lesson, students counted the number of points scored during the lesson.

To check that the student understands the feedback

Students to place their bags in designated areas to avoid minor accidents.

During the work with the different materials (pen, pencil, spring, sharp objects) students must follow SAFETY RULES in the physics lab.

During the break time the lab assistant have to ventilate the classroom.

Reflection

Were the lesson objectives/learning objectives realistic? Did all learners achieve the LO?

If not, why?

Did my planned differentiation work well?

Did I stick to timings?

What changes did I make from my plan and why?
