Teaching the concept of necessity

part of the grammatical rules of modal verbs and use it in every situation; the oversimplification
of modal verbs. Students learn some meanings of modal verbs but they only remember one of
them. In other words, they think each modal verb only has one meaning.
Using this method we have notices that some students were able to make analysis,
comparisons, even generalizations, while others were passive and not able to finish alone a given
task.
The observation papers used at the end of the lessons have helped us to analyze and
interpret all the data that have led to the final conclusions.

b) The method of conversation

The conversation method is based on a sincere dialogue between the researcher and the
subjects of the investigation. The final goal of the dialogue is for the researcher to gather the
students ‘useful data and opinions related to everyday activity at school.
In order to successfully use this method, we have started from reviewing the students‘
previous experience and knowledge and from defining any difficult psychological phenomena
that we might encounter in this study.
As a dialogue is a process in which two people have discussions in order to solve
problems, we needed a good plan, with clear and concrete questions which could be asked in a
pleasant atmosphere, so that many students could be involved in the dialogue. All the questions
were in close relation with the main aims of the research.
The most difficult parts were when some students were willing to answer different
questions and did not allow others to come up with their own ideas and feelings or when others
simply refused to have a conversation, apparently not being interested in the learning process.
That is why I have tried to help them become more aware about how they were
learning, reflect on this, and explore what procedures, materials, techniques and approaches
would help them learn more effectively.

c) The pedagogical experiment

The pedagogical experiment is about creating new situations, changing the natural
course of the investigation in order to check the working hypothesis. The studied phenomena are
observed in a situation especially created by the researcher. It is not about a general analysis, but
a particular one.
I used this method in three steps. First, I recorded the data regarding the experimental
