Differences in definitions of limit and continuity of functions as treated in courses on calculus and in rigorous undergraduate analysis yield contradictory outcomes and unexpected language. There are results about limits in calculus that are false by the definitions of analysis, functions not continuous by one definition and continuous by…

The study examined a new asynchronous model for online teaching, learning and assessment, called OTLA. It is designed for higher-education institutions and is based on LMS (Learning Management System) as well as other relevant IT tools. The new model includes six digital basic components: text, hypertext, text reading, lectures (voice/video),…

This 3-year study evaluated the effectiveness of the Second Step-Student Success Through Prevention (SS-SSTP) social-emotional learning program on increasing prosocial behaviors that could serve as protective factors against peer conflict and bullying among students with disabilities. Participants included 123 students with disabilities across 12…

Some studies on technology-supported peer feedback in the writing classroom claim that it reduces the threatening atmosphere caused by face-to-face interaction and that the discourse patterns and language use in the electronic feedback are more flexible than in spoken discourse. Others present a negative view that the comments generated from…

In many countries, novice teachers, or those with fewer than four years of experience, have a higher turnover rate than do more experienced teachers. Using teacher employment data, we examine whether schools in an American whole-school reform model are better able to retain novice teachers. Using survey data, we investigate whether novice teachers…

Many preschool language-focused interventions attempt to boost language and literacy skills in young children at risk in these areas of development, though the long-term effects of such interventions are not well-established. This study investigated kindergarten language and reading skills, specifically the subcomponents of vocabulary, decoding,…

This study investigated the effectiveness of using Google Docs in collaborative concept mapping (CCM) by comparing it with a paper-and-pencil approach. A quasi-experimental study was conducted in a physics course. The control group drew concept maps using the paper-and-pencil method and face-to-face discussion, whereas the experimental group…

This study investigates, through a cluster randomized trial, the impact of "Math in Focus," a core mathematics program modeled after instructional approaches used in Singapore, on third- through fifth-grade students' achievement in mathematics. The program is currently being used in more than 400 school districts in the United States.…

School choice has become a cornerstone of education reform plans across the nation especially in urban settings where immigrant populations often settle. Latino enrollment in charter schools has increased accordingly. Yet, little is known about how Latino parents, who arguably face significant linguistic, cultural, and economic barriers, engage in…

Studies that explore pedagogical content knowledge (PCK) in the field of mathematics education date back to the turn of the century in Turkey. In recent years, studies on PCK have gained momentum. Master's theses and doctoral dissertations have been written on PCK. In this context, there is a need to analyze the studies on PCK in Turkey to…

This praxis article outlines the value of using a critical and dialogical model (CDM) to teach multicultural social justice education to preservice teachers. Based on practitioner research, the article draws on the author's own teaching experiences to highlight how key features of CDM can be used to help pre-service teachers move beyond thinking…

Research documenting teachers' fragile understanding of proof and how it is advanced suggests that enhancing the role of proof in school mathematics will demand substantial teacher learning. To date, there is little research detailing what mathematical knowledge might support the teaching of proof or how professional development (PD) might afford…

Augmented reality (AR), a new generation of technology, has attracted the attention of educators in recent years. In this study, a MagicBook was developed for a neuroanatomy topic by using mobile augmented reality (mAR) technology. This technology integrates virtual learning objects into the real world and allow users to interact with the…

The increased prevalence of autism has created an increased challenge for teachers to incorporate specialized teaching strategies to address the unique educational and behavioral challenges facing children diagnosed with autism. Providing teachers with educational training opportunities will promote such learning. In the academic world,…

STEM education is a current focus of many educators and policymakers and the Next Generation Science Standards (NGSS) with the Common Core State Standards in Mathematics (CCSSM) are foundational documents driving curricular and instructional decision making for teachers and students in K-8 classrooms across the United States. Thus, practitioners…
