Psychological traits such as self-esteem explain how people differ from each other, but what explains the psychological traits and their development? Psychologists tend to explain individual differences and developmental trajectories of traits based on variables that are separate from the traits themselves. I argue that individual differences and developmental changes can also be explained by looking at the changes in the observable traits, looking within the trait and not outside of the trait.
While it is a good idea to track children’s academic development, there are some serious disadvantages to the use of standardized tests. Both the usage of tests and characteristics of the tests themselves could obstruct primary school students’ learning process, if we’re not careful.
