This paper reports on teachers? practical knowledge [PK] about peer interactions [PI] in learning mathematics. The focus is on high school teachers who consistently engaged students PI in their teaching. Data consisted of interviews and classroom observations. Findings indicate that these teachers have PK of students? roles in PI and learning…

In this paper we present results relating undergraduate student retention in science, technology, engineering, and mathematics (STEM) majors to the use of Peer Instruction (PI) in an introductory physics course at a highly selective research institution. We compare the percentages of students who switch out of a STEM major after taking a physics…

This study investigates pre-service mathematics teachers' concept images of radian and possible sources of such images. A multiple-case study was conducted for this study. Forty-two pre-service mathematics teachers completed a questionnaire, which aims to assess their understanding of radian. Six of them were selected for individual interviews on…

Differences in the perception of the difficulty level of integrating specific educational objectives into Mathematics teaching between beginner and experienced secondary school Mathematics teachers was examined. One hundred and seventeen Mathematics teachers from State Secondary Schools in Anambra, Nigeria were included in the investigation. A…

The Integrative Graduate Education and Research Traineeship (IGERT) program represents a substantial investment by the National Science Foundation (NSF) to improve the quality of graduate education, and ultimately, to increase the number of graduates better prepared to address our nation's 21st century scientific and technological needs. The…

The purpose of this study is to assess students' conceptual learning of electricity and magnetism and examine how these conceptions, beliefs about physics, and quantitative problem-solving skills would change after peer instruction (PI). The Conceptual Survey of Electricity and Magnetism (CSEM), Colorado Learning Attitudes about Science Survey…

The theory of action upon which high-stakes accountability policies are based calls for systemic reforms in educational systems that will emerge by pairing incentives for improvement with extensive and targeted technical assistance (TA) to build the capacity of low-performing schools and districts. To this end, a little discussed and often…

This study aimed on the process of teaching taxicab geometry, a non-Euclidean geometry that is easy to understand and similar to Euclidean geometry with its axiomatic structure. In this regard, several teaching activities were designed such as measuring taxicab distance, defining a taxicab circle, finding a geometric locus in taxicab geometry, and…

Building on Strunk, McEachin, and Westover (2011), the authors examine whether or not District Assistance and Intervention Teams (DAITs) have a differential impact on student performance across school and student characteristics. They use a quasi-experimental design to examine the impacts of DAITs on student achievement on math and English…

This paper considers a group of preservice teachers' construction of concept maps derived from y = x + 5 and y = [pi]x[squared] with emphasis on their conceptual understanding of function. The two statements are perceived to represent a number of different concepts with indications of compartmentalized knowledge structures that might prevent the…

School improvement initiatives have been the focus of recent political agendas, professional conferences, and publications. A recent educational change initiative in Indiana has been Project Lead The Way (PLTW). According to Rogers (2005) the state's technology education teachers have embraced PLTW and its infusion into the high school curriculum.…

The teaching and learning of mathematics in schools has drawn tremendous attention since the education reform in Taiwan. In addition to assessing cognitive abilities, Taiwan Assessment of Student Achievement in Mathematics (TASA-MAT) collects background information to help depict average student achievement in schools in an educational context.…

Spatial ability has been recognized as one of the most important factors affecting the mathematical performance of students. Previous studies on spatial learning have mainly focused on developing strategies to shorten the problem-solving time of learners for very specific learning tasks. Such an approach usually has limited effects on improving…

Examines the internal consistency and temporal stability of informant ratings from the revised NEO Personality Inventory (NEO PI-R) (P. Costa and R. McRae, 1992) and the Interpersonal Adjective Scale (IAS) (J. Wiggins, 1995) through ratings by 109 undergraduates of well-known adult targets. The estimates of internal consistency and temporal…

Urban at-risk elementary school students (n=72) who experienced both parent involvement (PI) and reciprocal peer tutoring interventions or the PI intervention alone reported higher self-concept and greater gains in mathematics achievement than students in practice control conditions. (SLD)
