The quality of measurement systems used in almost all natural sciences other than behavior analysis is usually evaluated through calibration study rather than relying on interobserver agreement. We demonstrated some of the basic features of calibration using observer-measured rates of free-operant responding from 10 scripted 10-min calibration…

This paper explores the difficulties that novice teachers confront at two economically, socially, and academically disadvantaged schools in the state of Nuevo Leon, Mexico. The researchers employed the action research tradition. Problems were identified using participant observation during reflexive workshops conducted with novice teachers and…

Adults with intellectual and developmental disabilities have medical conditions similar to those among the general population but with more complex presentation, a extended life expectancy, and increased risk of morbidity and mortality. These adults' health education has been inadequate. In this qualitative study, the author describes the…

Constructionism places an emphasis on the process of constructing shareable artefacts. Many virtual worlds, such as "Second Life", provide learners with tools for the construction of objects and hence may facilitate in-world constructionist learning experiences. However, the construction tools available present learners with a significant barrier…

The current study examines agreement among individuals with varying expertise in behavior analysis about the length of baseline when data were presented point by point. Participants were asked to respond to baseline data and to indicate when to terminate the baseline phase. When only minimal information was provided about the data set, experts and…

Experienced leaders face challenges that demand different leadership approaches to those of inexperienced leaders. The purposes of this article are to: (1) explore the leadership initiatives prominent for experienced leaders compared with inexperienced leaders; (2) examine the relationship between transformational leadership and these initiatives;…

How information literate are the Google generation, and what information literacy skills do they bring to university? For university libraries, understanding student prior knowledge provides a foundation on which to introduce appropriate learning activities during the first year. In 2009, in response to a new pedagogical model in health sciences,…

In this study, we use the US nationally representative Early Childhood Longitudinal Study-Kindergarten Cohort to examine inequalities in opportunities to learn mathematics. Specifically, we examine the characteristics of US students' elementary school math teachers and the instruction they provide. While our findings are consistent with previous…

This study explored the challenges facing 1st-year alternatively certified teachers of mathematics and science in urban middle schools. Four teachers, participants in a National Science Foundation (NSF)-funded Robert Noyce Scholarship Program, were followed from preservice training through their 1st year of teaching, having taken part in…

Cognitive scientists investigate mental models (how humans organize and structure knowledge in their minds) so as to understand human understanding of and interactions with the world. Cognitive and mental model research is concerned with internal conceptual systems that are not easily or directly observable. The goal of this research was to…

Recent reform efforts in mathematics education have stimulated a focus on learning trajectories. At the same time, a global increase in high-stakes testing has influenced instructional practices. This study investigated how four fourth grade teachers within a school planned and enacted lessons to understand what mediated their planning and…

This article examines how novice principals reflect on the adequacy or otherwise of their preparation. It looks at data drawn from the International Study of Principal Preparation (ISPP), and in particular a questionnaire of principals up to three years in post, in Scotland. The principals find much about their preparation has helped them gain…

Induction and mentoring of novice teachers have gained considerable worldwide attention. However, in the United Arab Emirates, graduates from teacher education programmes are recruited as teachers without being provided with any formal school-based support. They suffer from stress, overload, and low self-esteem and a high percentage leave…

The purpose of this study is to investigate the effects of a ubiquitous problem-based learning system (UPBLS) on students' question-raising performance in field inquiry activities. An experiment was conducted on an elementary school natural science course. A total of 43 sixth and fifth grade elementary students divided into experienced and…

Black, Wilson, and Yao have identified a very real tension felt by teachers today that has been created by No Child Left Behind (NCLB) in the United States and the National Curriculum Assessment in the United Kingdom. In many schools, formative assessment has either taken a backseat to summative assessment use, or many of the formative assessment…
