Single photon experiments involving a Mach-Zehnder interferometer can illustrate the fundamental principles of quantum mechanics, e.g., the wave-particle duality of a single photon, single photon interference, and the probabilistic nature of quantum measurement involving single photons. These experiments explicitly make the connection between the…

This study was performed to investigate the effects of live virtual classroom on students' achievement and to determine students' opinions about the live virtual physics classroom at distance learning. 63 second-year Distance Computer Education & Instructional Technology students enrolled in this study. At the live virtual physics classroom,…

This paper reports results of a design experiment regarding young children's concepts of mass measurement. The research built on an earlier study in which a framework of "growth points" in early mathematics learning and a related, task-based, one-to-one interview to assess children's understanding of the measurement of mass…

The purpose of this paper is to suggest and describe a methodological approach for studies of learning within school physical education (PE) in order to investigate and clarify issues of learning in an embodied practice. Drawing on John Dewey's work, and especially his use of the concept "transaction", a transactional approach is…

Teacher practices are essential for supporting learners in scientific inquiry practices of framing research questions, designing and conducting investigations, collecting data, and drawing conclusions. This study examines instructional practices of two Grade 11 Physical Science teachers engaged in teaching practical investigations. Data were…

This article reports on a study of academics who observed their colleagues' teaching at a large research-intensive university in Australia. These academics had completed peer observation as part of a foundations programme designed for those new to teaching or new to the university. Survey responses and interview transcripts form the basis of an…

This study examines the effect varying models have on student understanding of fractions. The study addressed the question of what students know and understand about fractional concepts through the use of discrete and continuous models. A sample of 54 students in kindergarten and 3rd grade were given an interview pretest, participated in…

This paper reports on a national study that explored primary pupils' attitudes towards and experiences of school science in the Republic of Ireland. The study focussed on collecting data from children and in doing so recognises the importance of children's views as an essential part of reviewing curriculum implementation. The findings of this…

What are the nature, forms, and roles of metaphors in mathematics instruction? We present and closely analyze three examples of idiosyncratic metaphors produced during one-to-one tutorial clinical interviews with 11-year-old participants as they attempted to use unfamiliar artifacts and procedures to reason about realistic probability problems.…

This report describes how teachers support ninth-grade students who are doing scientific investigations in Natural Sciences in South African schools. This is of interest as allowing students to participate in inquiry-based investigations is a significant shift from traditional practices. It presents a new challenge to teachers as it signals an…

This study investigated the extent to which higher-order thinking skills are promoted in social studies classes in high schools that are implementing smaller learning communities (SLCs). Data collection in this mixed-methods study included classroom observations and in-depth interviews. Findings indicated that higher-order thinking was rarely…

This study investigates the beliefs and practices of seven high school chemistry teachers as a result of their participation in a year-long inquiry professional development (PD) project. An analysis of oral interviews, written reflections, and in-class observations were used to determine the extent to which the PD affected the teachers' beliefs…

Russell Tufts University This study examines the potential of designing and teaching online courses to prompt university faculty members to reflect on the essence of good teaching, and as a result reconsider their beliefs concerning effective pedagogy. A phenomenological investigation was conducted based on interviews with six long-time university…

The researchers described in this case study how Service Learning was incorporated within the context of an early childhood program where the teachers used the Project Approach. The Service Learning project was embedded in an investigation about water and was designed to help tsunami victims in Asia. Participants included two teachers and 12…

This prospective, mixed-methods study investigated how the nature of joint activities between volunteer mentors and student mentees corresponded to relationship quality and youth outcomes. Focusing on relationships in school-based mentoring programs in low-income urban elementary schools, data were obtained through pre-post assessments,…
