    Objective Evaluation Criteria for Shooting Quality of Stereo Cameras over Short Distance

    Stereo cameras are the basic tools used to obtain stereoscopic image pairs, which can lead to truly great image quality. However, some inappropriate shooting conditions may cause discomfort while viewing stereo images. It is therefore considerably necessary to establish the perceptual criteria that can be used to evaluate the shooting quality of stereo cameras. This article proposes objective quality evaluation criteria based on the characteristics of parallel and toed-in camera configurations. Considering the different internal structures and basic shooting principles, this paper focuses on short-distance shooting conditions and establishes assessment criteria for both parallel and toed-in camera configurations. Experimental results show that the proposed evaluation criteria can predict the visual perception of stereoscopic images and effectively evaluate stereoscopic image quality

    FRAMING CRAFT AND PERFORMANCE IN HYBRID PUPPETRY WORKSHOPS

    Prototyping Puppets combines craft and performance in a puppet making STEM workshop for informal learning. We report on its final evaluation in two events (n=10 and n=13) to show how the design addressed black boxing of technology through a craft-centric approach and successfully engaged different student populations through an educational framing that included performance practice. The informal learning workshops are aimed at 5th grade level students and cover CSTA and NCSS learning objectives. First, the problem space is laid out and the approach of the project introduced. Second, the design realization is briefly covered. Third, the final evaluation of the design in two workshop conditions is presented using qualitative as well as quantitative data. Students showed self-perceived   increases particularly in their attitudes toward technology. These results are discussed before we report on the adaptation of the workshop for different conditions to illustrate the flexibility of the basic set up

    An examination of a mode of curriculum delivery in which science is integrated with design and technology in the primary school

    This paper describes a curriculum development project in which formal science lessons are located within a short design and technology project. The objective is to examine one model of curriculum delivery in which science is integrated with design and technology in order to enhance learning in both subjects. The approach is illustrated by describing the results of a project in which units of work from the National Exemplar Schemes of Work for science and design and technology (QCA, 1998) are used. Some conclusions are drawn as to how pupils might be helped to gain the appropriate science knowledge they need for designing and making by adapting the nature of the science activities

    Learning to remember: The early ontogeny of episodic memory

    AbstractOver the past 60 years the neural correlates of human episodic memory have been the focus of intense neuroscientific scrutiny. By contrast, neuroscience has paid substantially less attention to understanding the emergence of this neurocognitive system. In this review we consider how the study of memory development has evolved. In doing so, we concentrate primarily on the first postnatal year because it is within this time window that the most dramatic shifts in scientific opinion have occurred. Moreover, this time frame includes the critical age (∼9 months) at which human infants purportedly first begin to demonstrate rudimentary hippocampal-dependent memory. We review the evidence for and against this assertion, note the lack of direct neurocognitive data speaking to this issue, and question how demonstrations of exuberant relational learning and memory in infants as young as 3-months old can be accommodated within extant models. Finally, we discuss whether current impasses in the infant memory literature could be leveraged by making greater use of neuroimaging techniques, such as magnetic resonance imaging (MRI), which have been deployed so successfully in adults
