2.1.What is strategy? Strategy (from Greek στρατηγία stratēgia, “art of troop leader; office of general, command, generalship”[1]) is a general plan to achieve one or more long-term or overall goals under conditions of uncertainty.Strategy is important because the resources available to achieve goals are usually limited. Strategy generally involves setting goals and priorities, determining actions to achieve the goals, and mobilizing resources to execute the actions.[3] A strategy describes how the ends (goals) will be achieved by the means (resources).[4] Strategy can be intended or can emerge as a pattern of activity as the organization adapts to its environment or competes.[3] It involves activities such as strategic planning and strategic thinking.Teaching strategies refer to the methods, techniques, procedures and processes that a teacher uses during instruction. It is generally recognised that teaching strategies are multidimensional and their effectiveness depends on the context in which they are applied.


2.2.What is CEFR?
The Common European Framework of Reference for Languages (CEFR) is an international standard for describing language ability. It describes language ability on a six-point scale, from A1 for beginners, up to C2 for those who have mastered a language. This makes it easy for anyone involved in language teaching and testing, such as teachers or learners, to see the level of different qualifications. It also means that employers and educational institutions can easily compare our qualifications to other exams in their country.Although the CEFR is “European,” it is used in many countries around the world to talk about language proficiency. Because the CEFR is international, it’s very helpful for language learners and language teachers to talk about levels. There are six levels in the CEFR: A1, A2, B1, B2, C1, and C2. If you’re familiar with the idea of English language standards, the CEFR is similar.The CEFR doesn't describe language in terms of number of vocabulary words or grammar structures. The CEFR focuses on what students can do with the language. For example, students at level B1 can give descriptions on a variety of familiar subjects related to their interests. C1 students can give clear, well-structured descriptions of complex subjects. That’s why the CEFR can be used for any language, not just English. Learning your CEFR level can be really helpful to you as an English student!
