It is expected that most engineering students have solidified spatial thinking skills during K-12 schooling. However, according to what we know about geometry learning and teaching, spatial thinking probably needs to be explicitly taught within…

A study investigated the applicability of the theory of tentative developmental stages in English-as-a-Second-Language (ESL) development (TDS), which posits specific sequences for specific language features and hypothesizes developmental stages that cut across those sequences. The six stages are defined by specified combinations of three speech…
