In the mathematical literature on analytical geometry, various notions of the conics' eccentricity correspond to different approaches to these curves. After making a comparative analysis of well-known textbooks to determine coincidences and differences between the various concepts of eccentricity, as well as how the authors explain the…

In this article, we report the results of research that explores the intra-mathematical connections that high school students make when they solve Calculus tasks, in particular those involving the derivative and the integral. We consider mathematical connections as a cognitive process through which a person relates or associates two or more ideas,…

Regardless of the social or economic status of a student, it is a fact that math is always present. This discipline is considered as a competitive tool for achieving a more productive life. However, the gap in academic achievement is big. Consequently, in the last decades the research on education has set attention on this point. Therefore, this…

In impoverished communities in Mexico, most adolescent mothers do not attend school; but typically, they become pregnant once they dropped out. Understanding the experiences of adolescents who have had a pregnancy and continue in school is complicated since few manage to do it. The goal of this study is to describe experiences within the family…

This paper reports a qualitative research that identifies the characteristics of good mathematics teaching from the perspective of Mexican high school students. For this purpose, the social representations of a good mathematics teacher and a good mathematics class were identified in a group of 67 students. In order to obtain information, a…

Many teacher education programs include different forms of teachers doing research. Be it in the form of action research or general inquiries about their practice, it has been argued that when teachers do research on their own practice, they are able to take a more reflective stance towards their work which is necessary to bring about educational…

In spite of the fact that public schools were established to prepare students for citizenship, the alignment of teaching practice with this goal is poor. In part, this is because the knowledge base about the efficacy of curricular and pedagogical approaches in supporting specific civic outcomes is limited, as is our knowledge about the extent to…

This study uses a moving windows self-paced reading task to assess both text comprehension and processing time of authentic texts and these same texts simplified to beginning and intermediate levels.
