You can't always sketch what you want: Understanding Sensemaking in Visual Query Systems

Visual query systems (VQSs) empower users to interactively search for line charts with desired visual patterns, typically specified using intuitive sketch-based interfaces. Despite decades of past work on VQSs, these efforts have not translated to adoption in practice, possibly because VQSs are largely evaluated in unrealistic lab-based settings. To remedy this gap in adoption, we collaborated with experts from three diverse domains---astronomy, genetics, and material science---via a year-long user-centered design process to develop a VQS that supports their workflow and analytical needs, and evaluate how VQSs can be used in practice. Our study results reveal that ad-hoc sketch-only querying is not as commonly used as prior work suggests, since analysts are often unable to precisely express their patterns of interest. In addition, we characterize three essential sensemaking processes supported by our enhanced VQS. We discover that participants employ all three processes, but in different proportions, depending on the analytical needs in each domain. Our findings suggest that all three sensemaking processes must be integrated in order to make future VQSs useful for a wide range of analytical inquiries.Comment: Accepted for presentation at IEEE VAST 2019, to be held October 20-25 in Vancouver, Canada.

A Comparison of Perceptions of Knowledge and Skills Held by Primary and Secondary Teachers: From the Entry to Exit of Their Preservice Programme

The purpose of this study was to investigate if there were differences in the levels of pedagogical knowledge and skills as perceived by the student teachers who were enrolled in the Primary and the Secondary Post Graduate Diploma in Education programme at the National Institute of Education in Singapore. 170 Primary and 426 Secondary student teachers participated in the study. The results showed that there were no significant differences at the beginning of the programme between the two cohorts. However, there were significant differences between the two groups at the end of programme, with the Primary student teachers tending to perceive themselves as gaining more pedagogical knowledge and skills by the end of their initial teacher preparation programme than the Secondary student teachers

Escuelas promotoras de la salud: un programa multicompente para prevenir los riesgos conductuales en adolescentes (2014-2017)

DOI: 10.26439/persona2020.n023(1).4834 This article is based on the analysis of the systematization of the Health Promoting School project implemented in Lima, Peru, from 2014 to 2017 by an agreement between the International cooperation agency of South Korea and the Ministry of health in Peru. A description of the phases developed, the strategies used, and the alliances built for their implementation will be presented. For that purpose, a review of secondary sources and interviews to key players as primary sources were made. The project considered the prevention and health promotion paradigms as complementary ones.DOI: 10.26439/persona2020.n023(1).4834 Este artículo se basa en el análisis de la sistematización del Proyecto de las Escuelas Promotoras de la Salud, implementado en Lima, Perú, del 2014 al 2017, a través de un acuerdo entre la Agencia de Cooperación Internacional de Corea del Sur, y el ministerio de Salud de Perú. Se describe el desarrollo de las fases del proyecto, las estrategias que se usaron, así como las alianzas que se construyeron para la implementación del proyecto. Para el análisis se revisaron fuentes secundarias y se entrevistaron a los agentes clave, como fuentes primarias. Consideramos que los paradigmas de prevención y promoción de la salud deben ser considerados como complementarios
