Teaching Biology with concept clearance to students at Grade 9-12 where the students need to have practical approach

I have Master Honors in Genetics with the specialty of Biology and Cell Biology. Having a rich experience of 15 years of teaching I well understand the behavior of learner and how to satisfy one's thirst of learning. In my view teaching is not one way but it is two way communication. Teacher needs to evaluate the learner understanding level of the concept and enhance as per his capability. Biology is a theoretical and practical science and it is important for the teacher to give a visualized approach to the students. It is vey important to follow Blooming Taxonomy pedagogy at the given grade level.
