Science teaching is a learning activity that largely determines the national goal of general education, the definition of goals and objectives protected by the new document. Figuratively, the dilemma is a situation of assessment when a person is faced with an unfavorable machine, there is only one choice. Dilemma teaching belongs to problem-based teaching methods. The problem of learning is to equip students with not only knowledge, but also to challenge this knowledge to life. Accordingly, the goal of teaching is to develop the student's critical, analytical, creative thinking and independent decision-making skills. When teaching with dilemmas, the so-called VaKE method can be maintained, which means "education in dimensions", the confrontation of knowledge and characteristics. In both cases, the results of teaching and the results of teaching with VaKE, the theoretical foundations are the same, both are fundamental structural ideas, but the novelty is that students. see who is registered with their apartment. Our opinions, the role of teaching is to give students the opportunity to choose, to develop a free personality and to strengthen their feelings, and to play a big role in teaching and learning. Environment and sky projects, all worthy of these goals.
