First of all, I'd like to emphasize that activities in class much depend on planning, that's why it's so important to make all the necessary preparations for teaching to provide a strong and authoritative background for good educational results.
The information provided was gathered with the help of analyzing quantitative and qualitative data of questionnaires and test results provided for students at the beginning and in the end of teaching process to study the results of teaching methods and their impact on group learning.
