Preliminary development of a simple statistical tool for estimating mental model states from a diagnostic test

Science knowledge is reflected in mental models that students tend to form when dealing with science phenomena. One way to identify students’ mental models about scientific concepts is the use of diagnostic tests (inventories). Even though several statistical approaches and tools intended for the an...
