Understand the definition of a longitudinal study: it involves observing or assessing the same participants repeatedly over an extended period of time to track changes and development.
Review each option and identify whether the study design involves repeated observations of the same individuals over time.
Option 1 describes observing a classroom for one week, which is a short-term observation and not longitudinal.
Option 2 involves surveying college students about past experiences, which is retrospective and not longitudinal because it does not follow participants over time.
Option 3 describes following the same group of children from age 5 to age 18 and assessing them every three years, which fits the definition of a longitudinal study perfectly.
