Identifying Alternative Concepts In Some Chemistry Topics Using The Diagnostic Branched Tree Technique

This study aimed to identify whether students possess alternative concepts in certain chemistry topics, through making use of a concept test which was developed using the Diagnostic Branched Tree (DBT) technique which is an alternative to traditional assessment and evaluation instruments. DBT differs from traditional assessment and evaluation instruments in terms of its structure and goal. The study adopts a survey method. The study was conducted with 222 teacher candidates who were studying at Dumlup？nar University, Education Faculty, Primary School Teaching and Science Teaching Departments and who participated in the study on a volunteer basis. The study data was analyzed using descriptive statistics. According to the analysis results of the concept test which was developed through the DBT technique, teacher candidates were found to possess alternative concepts emphasized in related chemistry literature such as matter and its features, elements, compounds, solutions and colligative features, metals, physical and chemical changes, acids and bases, heat and temperature issues
