The purpose of this study was to explore the perceptions of Secondary Math Teachers (SMTs) concerning the influences that affect teaching practices and also investigate the possible existence of pluralistic ignorance concerning the way SMTs perceive the effects of influences on their own teaching practices versus the way they perceive the effects…

Given the growing economic returns to education (Psacharopoulos & Patrinos, 2004) and the overwhelmingly high educational expectations of American high school students (Domina et al., 2011; Goyette, 2008), one might expect nearly all U.S. high school students to take as many academic courses as they can. Consistent with this expectation, much…

The classroom implementation of open-ended mathematics tasks, such as Model-Eliciting Activities (MEAs), can be challenging for teachers. This case study research considers a teacher, Adam, implementing a lesson intended to be an MEA on graphical antiderivative. We describe the lack of alignment of the written, intended and enacted curricula that…

A teacher's instructional planning that is enacted in his classroom practice and that potentially impact on his students' knowledge and beliefs could be understood as an individual belief system dependent from his actual teaching and learning experience. Individual belief systems might be contradictory when we regard different teachers or one…

We present the second stage of a study within the context of geometry, whose aim is to investigate relationships between and influence of visualization, the concept images of students concerning geometrical concepts and their definition, and students' ability to prove. We focus on links between the understanding of the definition's role in…

Despite their apparent simplicity, the concepts of square numbers and square roots are problematic for high school students. I inquired into students' understanding of these concepts, focusing on obstacles that students face while attempting to solve square number problems. The study followed a modified analytic induction methodology that included…

Research on flipped instruction with English Language Learners (ELLs) is sparse. Data-driven flipped research conducted with ELLs primarily involves adult learners attending a college or university. This study examined the academic performance of secondary ELLs who received flipped instruction in an algebra course at a newcomer school compared to…

This paper draws on self-determination theory (SDT) to explore reasons for college students' decisions to either continue or change directions (and hence their persistence) from their STEM-intending majors. We therefore sought to gain insight into why some college students persisted in their STEM-intending degree programs while others, faced with…

The exploration of proportional relationships is foundational to the mathematics studied in the middle grades and beyond. Research has shown that an early emphasis on procedures often leaves students with a shallow understanding of the important underlying mathematical concepts of proportional relationships. One approach that addresses the needs…

This paper describes an experience of same-age peer tutoring conducted with 19 eighth-grade mathematics students in a secondary school in Castellon de la Plana (Spain). Three constructs were analysed before and after launching the program: academic performance, mathematics self-concept and attitude of solidarity. Students' perceptions of the…

Student Mobility is increasing on Long Island, NY, the site of the present study related to the demographic changes of increasing immigration and poverty. Mobile students often struggle academically, and are at risk for school drop-out or failure. Mobility is sometimes combined with other risk factors such as gender, ethnicity, limited English,…

Technology may play a critical role in impacting student engagement, specifically within an assessment context. Using a mixed methods approach, I examined the relationship between varying degrees of technology-enhancements applied in a mathematics performance task on the outcome of student cognitive engagement. Using a counterbalanced…

We used a situative perspective to examine teachers' perceptions of a professional development intervention that integrated lesson study, video clubs, and animation discussions. The analysis of interviews with the five geometry teachers who participated in the intervention during two consecutive years showed three characteristics of professional…

The purpose of this study is to inform and further the discussion of academic (i.e., teachers and school counselors) and non-academic (i.e., parents, family, friends, etc.) validating agents on Latina students' mathematics and science self-concepts. This study found a relationship between Latina students' interactions with academic and…

A professional development program (PSPD) was implemented to improve in-service secondary mathematics teachers' content knowledge, pedagogical knowledge, and self-efficacy in teaching secondary school statistics and probability. Participants generated a teaching resource website at the conclusion of the PSPD program. Participants' content…
