Problems:
Misconceptions in the use of terminologydescribing evolutionary theories.

In the Swedish curriculum for the compulsory schoolone of the aim of biology education is that the student should:
“get an insight into the world view of science with the theory of evolution as afoundation”

Ann Mutvei, Tomas Bollner, Jan-Eric](https://reader034.vdocuments.us/reader034/viewer/2022042122/5e9d465f8f20ad0533430b15/html5/thumbnails/5.jpg)
One of the core content of biology educationfor the compulsory school year 6 is:
Development of life and adaptation of organisms to different habitats

Ann Mutvei, Tomas Bollner, Jan-Eric](https://reader034.vdocuments.us/reader034/viewer/2022042122/5e9d465f8f20ad0533430b15/html5/thumbnails/6.jpg)
One of the core content of biology educationfor the compulsory school year 9 is:
Comparisons from an evolutionary perspective between man and other organisms.
Evolutionary mechanisms and their outcomes, and also heredity and the relationship between heredity and the environment.

One of the knowledge requirement of biologyeducation in compulsory school year 6 is:
“pupils can talk about the development of life and give examples of the adaptation of organisms to different living environments”.

Do the student use evolutionary concepts when explaining evolution?
![Page 10: Evolution, teaching and assessment of students in …...Evolution, teaching and assessment of students in pre-service primary school teacher education. Ann Mutvei, Tomas Bollner, Jan-Eric](https://reader034.vdocuments.us/reader034/viewer/2022042122/5e9d465f8f20ad0533430b15/html5/thumbnails/10.jpg)
Are the students able to explain evolution without using specific evolutionary concepts?
![Page 11: Evolution, teaching and assessment of students in …...Evolution, teaching and assessment of students in pre-service primary school teacher education.

Are there misconceptions when using the terminology to explain evolutionary theories?

During the first five weeks, the student wrote four short reflections about something from the course literature that could be interesting for children.

At the end of the course (after 7 weeks) the student wrote a short reflection about evolution.

At the end of the course (after 7 weeks) the student wrote a short reflection about evolution.
39 written reports were analyzed by scoring the numbers of concepts used.

22 different concepts were found in the short reflections about evolution.

The students ability to use the concepts were grouped in 4 different groups:
Group 1: 0 used evolutionary conceptGroup 2: 1 used evolutionary conceptGroup 3: 2-3 used evolutionary conceptsGroup 4: 4 or more evolutionary concepts

Results
22 different concepts were found in the short reflections about evolution.
There is a correlation between the use of evolutionaryconcepts and the use of biological concepts up to a certain level.

22 different concepts were found in the short reflections about evolution.There is a correlation between the use of evolutionaryconcepts and the use of biological concepts up to a certain level.Some students using few concepts had a good understanding of the theory of evolution.

Conclusions:
Some but not all of the studentsused both biological and strict evolutionary concepts to explain evolutionary theories.
There are a limited number of students usingstrict evolutionary concepts.
