The findings showed that many students, especially those with diagnosed learning disabilities, made minimal growth in fraction knowledge and…

Research has suggested that different strategies used when solving fraction problems are highly correlated with students' problem-solving accuracy. This study (a) utilized latent profile modeling to classify students into three different strategic developmental levels in solving fraction comparison problems and (b) accordingly provided…
