‘Full of activity, new ideas, the will to succeed etc; forceful’ (Longman Dictionary of Language and Culture).

According to the Webster’s New Dictionary of Synonyms, dynamic is ‘live, active, operative’. Analogous words given by this dictionary: potent, forceful, intense, vitalizing, energizing.

I also found intriguing that the dictionaries only gave examples related to business and administration: an honest and dynamic businessman or a dynamic young businessman.

Considering the definitions and the fact above, I immediately related dynamism to management and enterprising. Then, to teacher roles.

H. Douglas Brown describes five roles for teachers and one of them is the teacher as a manager.

‘This metaphor captures your role as one who plans lessons and modules and courses, one who structures the larger, longer segments of classroom time, but who then allows each individual player to be creative within those parameters. Managers of successful corporations, for example, retain control of certain larger objectives of the company, keep employees pointed toward goals, engage in ongoing evaluation and feedback but give freedom to each person to work in their own individual areas of expertise. A language class should not be markedly different.’

Jeremy Harmer does not describe a manager, but he believes the teacher is an organizer. According to this author

‘The success of many activities depends on good organization and on the students knowing exactly what they are to do… The main aim of the teacher when organising an activity is to tell the students what they are going to talk about (or write or read about), give clear instructions about what exactly their task is, get the activity going, and then organize feedback when it is over.’

Conclusion
Following this line of thought, a dynamic teacher is the one full of ideas, with varied activities, full of energy and the one who is able to manage and organize the course effectively. Finally, a dynamic teacher sets clear objectives and gives clear instructions. I know it doesn’t look obvious or you may even think it’s totally wrong, but it sure is a relevant point of view.
