A researcher is interested in investigating how teaching style—structured versus unstructured—affects the learning of vocabulary in children who are developmentally delayed, typically developing, or gifted. The researcher organizes an after-school program, and all participants are given a pretest. The program consists of 30-minute sessions two times a week for four weeks. Participants are randomly assigned to the high-structure course or the low-structure course. All courses focus on word knowledge and vocabulary. At the end of the program, the researcher assesses word knowledge for developmentally delayed, typical, and gifted students in the high-structure group, as well as developmentally delayed, typical, and gifted students in the low-structure group. The researcher is wondering whether the level of structure—high versus low—might affect the participant groups differently.
