Similarities and Differences Background Information

The fundamental cognitive process of comparing ideas and objects greatly aids understanding, learning, and communication. The use of similarities and differences can serve as prerequisite and parallel skill for many other aspects of semantic knowledge. These include categories, examples, functions, attributes, parts, antonyms and synonyms.

The ability to group objects by means such as semantic similarities is a critical factor in learning words outside one’s direct experience (Borovsky and Elman, 2006). The research that supports direct instruction of similarities and differences is strong. Among the findings are that students benefit by having similarities and differences pointed out by a teacher in an explicit manner and that graphic organizers, such as Venn diagrams, comparison tables or charts, and hierarchical taxonomies, that help students construct their own comparisons, can significantly boost student achievement (Focus on Effectiveness, 2005).

A general knowledge of similarities and differences greatly overlaps with several skills common to assessments. These include metaphors, analogies, and comparing/contrasting. Teaching this relatively simple skill can greatly influence how well a child demonstrates understanding of concepts with previous familiarity. For example, a child may be able to state or identify that Canada and Mexico are countries, but be unable to answer the question “How are Canada and Mexico alike?”

One verbal comprehension core subtest of the WISC-4 tests similarities. Analogies have long been standard fare on tests such as the SAT (though controversially, not since 2005), ACT, and GRE. Tests used by SLPs with this skill include the CASL, EOWPVT, LPT, PLS-4, and TOLD-I.

Cher will identify two functional words that are similar, when given a similarity and foils. For example, “Which two of these play music?”

Bono will label one similarity and/or one difference between two age appropriate words. For example, “How are a comma and a period alike?’

Madonna will label one similarity and one difference between two curriculum relevant vocabulary words. For example, “Tell me how thunder and lightning are alike, and how they’re different.”
