“…Moreover, some meta-analysis studies found that those factors, such as class capacity, educational level, intervention duration, participant, mathematical content, instrument, and school geographical location significantly differentiated students' mathematics achievement in ICT-based or -assisted mathematics learning [9-11, 86, 88, 91, 93, 94, 97, 100, 101]. Several meta-analysis studies, however, revealed that there was no sufficient evidence to state that these factors, such as class capacity, educational level, intervention duration, participant, mathematical content, instrument, and school geographical location significantly differentiated students' mathematics learning outcome in mathematics learning activities utilizing ICT [13,82,84,85,87,89,90,92,95,96,98,99,106]. Of those reports, it can be hypothesized that several factors, such as class capacity, educational level, participant, intervention duration, learning environment, technology used, mathematical content, instrument type, and the role of technology have a potential role in differentiating students' numerical literacy in ICT-based or -assisted mathematics learning.…”
