theories are beliefs

Some examples of how learners understood the status of theories:

"[a theory is] something that explained some things… it's what you believe is true or false"

'Ben', 13-14 year old reported in Taber, K. S., Billingsley, B., Riga, F., & Newdick, H. (2015). English secondary students' thinking about the status of scientific theories: consistent, comprehensive, coherent and extensively evidenced explanations of aspects of the natural world – or just 'an idea someone has'. The Curriculum Journal, 1-34. doi: 10.1080/09585176.2015.1043926

"something that isn't proven, that people believe in, that's what I think a theory is"

'Chas', 13-14 year old reported in Taber, K. S., Billingsley, B., Riga, F., & Newdick, H. (2015). English secondary students' thinking about the status of scientific theories: consistent, comprehensive, coherent and extensively evidenced explanations of aspects of the natural world – or just 'an idea someone has'. The Curriculum Journal, 1-34. doi: 10.1080/09585176.2015.1043926

"a theory is a belief supported by evidence…the thing about scientific theories is, a lot of them can't be proved"

'Dean', 13-14 year old reported in Taber, K. S., Billingsley, B., Riga, F., & Newdick, H. (2015).
