The generalisation of linguistic constructions is performed through analogical reasoning. Children with developmental language disorders (DLD) are impaired in analogical reasoning and in generalisation. However, these processes are improved by an input involving variability and similarity. Here we investigated the performance of children with or…

Abilities in scientific thinking and reasoning have been emphasized as core areas of initiatives, such as the Next Generation Science Standards or the College Board Standards for College Success in Science, which focus on the skills the future will demand of today's students. Although there is rich literature on studies of how these abilities…

Argues that the limited results achieved so far by empirical educational research are a result of a fundamental difference in the generalized concepts used therein and the abstract concepts used in the natural sciences. Discusses the work of Galileo and Newton to clarify the difference between generalization and abstraction. (DMM)

Mathematical tasks calling for relational thinking were given to 60 children of Indian, Pakistani, or Bangladeshi origin who had spent their school lives in England, 60 who had arrived within the past 3 years, and 60 British children. Differences in the ability to abstract, hypothesize, and generalize were studied. (KC)
