The study of students' use of representations is one of the main topics of physics education research and is guided by the overarching field of semiotics. In this paper we compare two semiotic frameworks, one coming from didactics of mathematics and one from physics education research; "the theory of registers of semiotic…

This study was undertaken to test the findings of Dienes and Jeeves concerning the strategies used by students to learn mathematical structures. The study also proposed to determine whether students are consistent across structures and embodiments in the strategies they use and the evaluations they give. One hundred adolescent girls were given…

Investigated was the mathematics achievement of several hundred junior high school students, believed by their counselors and teachers to be "slow learners." This investigation focused on two critical problems: (1) whether some children benefit from less rapid pacing of material, and (2) which are the strongest predictors of achievement…

Used are test and interview data to extract evidence as to what level tenth graders have coordinated the worlds of arithmetic and algebra and can move freely between them. More dissociation is shown than was expected. (Author/MVL)

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…
