Anotace:
Evolutionary trees are among the most useful tools in biology, therefore, students should be taught how to correctly interpret
them. Using tree-like diagrams to depict relationships among organisms is easily understandable, but students often struggle
with interpretations of particular graphical forms of trees. Based on my literature review of the most commons problems,
I prepared a series of educational activities for Czech upper secondary school students. The series introduces basic principles
of construction and interpretation of evolutionary trees and also addresses common mistakes.
To prepare the educational series, I reviewed practical activities focused on evolution that have already been published,
but that are designed for older students (usually for biology majors) and written in English. Therefore, I adapted and simplified
suitable activities for my target group of students. Specifically, I prepared several practical activities and included
them in an educational series of 4 × 45 minutes. If needed, most of the activities can also be used separately or the series
can be reduced to its first half. The activities are designed with an emphasis on the active role of students who will work
with different sources of information, try to construct their own evolutionary trees and interpret existing ones. I tested
the series at an upper secondary school and it proved to be easily applicable, effective and appealing, based on feedback
from the students.
