摘要: The Test of Logical Thinking (TOLT) and the Group Assessment (GALT) are two instruments most widely used by science educators researchers to measure students’ formal reasoning abilities. Based on Piaget’s cognitive development theory, thinking ability has been shown be essential for student achievement in chemistry courses. major difference between TOLT GALT is concrete items relating conservation mass volume, which contains over above TOLT. first intent this study was determine whether represent an advantage general population terms test reliability, discriminatory power, item bias. Accordingly, “TOLT + 2” (TOLT with extra items) were each administered a sample 900 students enrolled first-semester chemistry. not observed provide any advantage, DIF analysis suggests that te...
