In biology, it is very difficult for the students to remember all the information for each living thing, how the teacher can mitigate this lesson?

In my opinion the best way is to use common every day examples and than step by step to add more difficult details, groups and so on.. 

Also new technology helps a lot, considering it helps to visuals new materials. 

 

Using real-life context and technology help a lot  to fix the information in their minds e.g., at the end of each month students may have  made a collaborative slideshow of a accomplished topic, and as a teacher you may also show them short videos that simplify a process or a concept. You can also encouraged  them to think about the relationship among livings organisms and make connections, making connections is a great way to remember . Mind map is also great method.

 

Mind maps could be utilized in order to remember all info related to each individual living creature .

Effecrive teachers have the ability to teach from their heart not from the book, so her words will be used by students.Therefore using real experiments applied on animals the lesson is easy to be remember.

One of the solution to this problem is spiralling i.e. repeating the content taught again and again so that it gets inculcated into the minds of the learners.

First of all the teacher is an expert in all the information related to the topic or lesson in Biology. 

Teachers must make handouts of all the terms, definition and the important information and distribute to the students BEFORE the lesson is dealt in the classes. Then the lesson plan must be framed and shared with the students so that they refer to the handouts and come prepared to learn about the terms, definition and also know the day plan. 

After the lesson at the end of the class, there must be a refresher test that has questions with objective/selective answers. This is like a revision and a ready reckoner for the students. 

If this is followed by teachers, it makes it easy for the students.
