Using crosswords in subject teaching

Target:

Organization of students’ work in class to consolidate knowledge of the topic being studied;

Control over students' knowledge in a non-traditional form;

Generalization and systematization of biological concepts on a specific topic;

Motivation to do homework;

Implementation of a differentiated approach to training.

Using themed crosswords in teaching(sheet with crossword puzzle is distributed to students)

1. Thematic Verification work in an unconventional form.

2. Individual additional task in class for students with a high pace of work (If a student does not have time to solve the crossword puzzle in class, he continues to work at home)

3. Creative homework for students to fill out and subsequently compose a crossword puzzle on the topic they have studied.

4. Individual homework for students with low motivation for homework (Solving a crossword puzzle involves actively working with the text of the paragraph).

5. Homework to prepare for the thematic test.

6. Individual homework based on the results of the thematic test work for students who have made a significant number of mistakes.
