Investigating on validity and reliability of concept map based tests scoring methods

Abstract

Concept maps usage expanding as an academic achievement measurement tools great a challenge in scoring them. This study introduces three scoring methods of the concept maps tests: (1) Relational method that in which a relationship between concepts separately was scored. (2) Structural method that based on scores was given to hierarchical organization of the concepts. (3) Similarity method that in which a student’s concept map compares with a teacher’s concept map and assign score for each section of the map. Critical validity, interrater reliability and discriminative reliability were used to identify the most appropriate method of scoring. Subjects of the research consist of 105 high school students in Tabriz that were present in four classes. Findings showed that the relational method of scoring has higher quantities of the indicators than other methods. Similarity scoring method has the lowest indices in comparison with two other methods.
