Two-Tier Human and Environment Concepts Diagnosis Test Development

This study was carried out with the aim of developing a two-tier diagnostic test human and environmental concept test for use in the 5th grade human and environment unit. The development of two-tier diagnostic human and environmental testing was carried out in three stages. In the first stage, the content of the subject was determined. In the second stage, students' misconceptions were determined. In order to identify misconceptions about human and environment, two different classes of 64 people were asked 5 open-ended questions about the environment. In addition, the reasons of misconceptions were investigated with the help of semi-structured interviews. In the last stage, the diagnostic test was developed by taking into consideration the misconceptions. The developed test was examined together with 4 faculty members who are experts in field education about the validity of the scope and determination of misconceptions. The final shape of the test is given according to the feedback of the experts. The two-tier diagnostic test prepared in this way can be used by researchers to identify misconceptions or can be used as data collection tools in conceptual change studies.
