A multiple baseline design across participants was used to evaluate the effects of video modeling with embedded instructions on training teachers to implement 3 preference assessments. Each assessment was conducted with a confederate learner or a child with autism during generalization probes. All teachers met the predetermined mastery criterion,…

Gargani and Strong claim to have developed and validated an observation system that requires only 4 hr of training, but one that can identify effective teachers using just 20 min of one video-taped lesson. They further contend that their six-item inventory requires little judgment from those who use it. They describe their instrument, the Rapid…

Previous electromyographic studies have reported that individuals with autism spectrum disorders (ASD) exhibited atypical patterns of facial muscle activity in response to facial expression stimuli. However, whether such activity is expressed in visible facial mimicry remains unknown. To investigate this issue, we videotaped facial responses in…

A rich understanding of key ideas in linear algebra is fundamental to student success in undergraduate mathematics. Many of these fundamental concepts are connected through the notion of equivalence in the Invertible Matrix Theorem (IMT). The focus of this paper is the ways in which one student, Abraham, reasoned about solutions to Ax = 0 and Ax =…

Aims: The use of fear appeals with disgusting graphical content is part of current practice in health campaigns. Previous studies have suggested both a detrimental and a beneficial effect of disgust in fear appeals on different types of outcome measures. We were interested in whether disgust in anti-smoking messages decreases or increases…

Developments in pedagogical knowledge in the teaching of social research methods have largely been generated through teachers reflecting on their practice. This paper presents an alternative approach to generating data through reflective dialogue between researchers, teachers and learners. The approach incorporates elements of video stimulated…

This paper reports the development of a scheme of characterising pedagogical practices in initial teacher education classes. The scheme is intended to provide baseline data on classroom pedagogical practices in Singapore's sole provider of initial teacher education (ITE). This study is original in that the research team has found no reports of…

This chapter describes the process and outcomes that follow from inviting students to explore deeper aspects of themselves through digital storytelling.

The Friends of the National World War II Memorial was established in 2007 to serve, in part, as an organization devoted to educating young people and visitors to the memorial in an effort to ensure that the lessons, legacy, and sacrifices of World War II not be forgotten. After 32 years of teaching history at West Springfield High School in…

We present a number of simple demonstration experiments recorded with high-speed cameras in the fields of gas dynamics and thermal physics. The experiments feature relatively slow combustion processes of pure hydrogen as well as fast reactions involving oxy-hydrogen in a stoichiometric mixture. (Contains 4 figures.)

The standard method to create dramatic color images in astrophotography is to record multiple black and white images, each with a different color filter in the optical path, and then tint each frame with a color appropriate to the corresponding filter. When combined, the resulting image conveys information about the sources of emission in the…

Participatory research methods argue that young children should be enabled to contribute their perspectives on research seeking to understand their worldviews. Visual research methods, including the use of still and video cameras with young children have been viewed as particularly suited to this aim because cameras have been considered easy and…

In this paper we propose and discuss a framework for analysing adults' work competences while construing mathematics-containing "themes" in two workplace settings: road haulage and nursing. The data consist of videos and transcribed interviews from the work of two lorryloaders, and a nurses' aide at an orthopaedic department. In the…

A three year study of digital video creation in higher education investigated the impact that creating short digital videos by university students in their final class of a teacher education program had on those students. Each student created a short video reflecting on the process of how he/she became a teacher. An analysis of the videos…

In recent years, the concept of Assessment for Learning (AfL) has travelled across countries, giving rise to a range of educational policy initiatives and school development projects. While researchers have focused on issues such as how formative assessment can support student learning and lead to more efficient classroom practices, less attention…
