Design of online practical lessons in colorimetry

Applied colorimetry is an important module in the program of the elective subject "Colour Science: industrial applications”. This course is taught in the Optics and Optometry Degree and it has been used as a testing for the application of new teaching and assessment techniques consistent with the new European Higher Education Area. In particular, the main objective was to reduce the attendance to lessons and encourage the individual and collective work of students. The reason for this approach is based on the idea that students are able to work at their own learning pace. Within this dynamic work, we propose online lab practice based on Excel templates that our research group has developed ad-hoc for different aspects of colorimetry, such as conversion to different colour spaces, calculation of perceptual descriptors (hue, saturation, lightness), calculation of colour differences, colour matching dyes, etc. The practice presented in this paper is focused on the learning of colour differences. The session is based on a specific Excel template to compute the colour differences and to plot different graphs with these colour differences defined at different colour spaces: CIE ΔE, CIE ΔE94 and the CIELAB colour space. This template is implemented on a website what works by addressing the student work at a proper and organized way. The aim was to unify all the student work from a website, therefore the student is able to learn in an autonomous and sequential way and in his own pace. To achieve this purpose, all the tools, links and documents are collected for each different proposed activity to achieve guided specific objectives. In the context of educational innovation, this type of website is normally called WebQuest. The design of a WebQuest is established according to the criteria of usability and simplicity. There are great advantages of using WebQuests versus the toolbox “Campus Virtual” available in the University of Alicante. The Campus Virtual is an unfriendly environment for this specific purpose as the activities are organized in different sectors depending on whether the activity is a discussion, an activity, a self-assessment or the download of materials. With this separation, it is more difficult that the student follows an organized sequence. However, our WebQuest provides a more intuitive graphical environment, and besides, all the tasks and resources needed to complete them are grouped and organized according to a linear sequence. In this way, the student guided learning is optimized. Furthermore, with this simplification, the student focuses on learning and not to waste resources. Finally, this tool has a wide set of potential applications: online courses of colorimetry applied for postgraduate students, Open Course Ware, etc.

Movimiento estudiantil en Chile, aprendizaje situado y activismo digital. Compromiso, cambio social y usos tecnológicos adolescentes

A partir del movimiento estudiantil que surge en Chile en 2011 el artículo reflexiona sobre la escuela como espacio de aprendizaje situado de tecnologías digitales audiovisuales y el modo en que este proceso puede impactar sobre la dimensión político-comunicacional de un movimiento social. Para ello, se describe y analiza el caso de una escuela donde la educación formal en lenguajes y tecnologías digitales se imbrica con el uso que hacen, estudiantes secundarias que se convierten en dirigentas estudiantiles, de aplicaciones y recursos de la web social y los llamados “social media” (youtube, blogs, redes sociales). Se trabaja con datos generados a través de entrevistas a informantes claves y una selección de videos creados por el estudiantado y subidos a internet. El contenido de las entrevistas es abordado desde el concepto de aprendizaje situado (Lave y Wenger, 1991) y los videos desde el concepto de videoactivismo (Askanius, 2013; Mateos y Rajas, 2014). Los resultados muestran que el uso concreto de herramientas digitales obtenidas en contextos educativos formales y dentro de procesos de movilización, genera a su vez nuevas experiencias de aprendizaje no-formal, que permiten tanto a estudiantes como docentes reflexionar sobre sus prácticas y mejorar su potencial comunicativo. Asimismo, muestran un uso acrítico de las herramientas digitales, lo cual constituye un llamado de atención respecto a la necesidad de incorporar los tópicos de privacidad y autocuidado en internet dentro de los contenidos a desarrollar por la escuela como espacio de aprendizaje digital.

The Influence of Space Layout, Technology and Teaching Approach on Student Learning: An Architectural Technology Perspective

Some would argue that there is a need for the traditional lecture format to be rethought in favour of a more active approach. However, this must form part of a bipartite strategy, considered in conjunction with the layout of any new space to facilitate alternative learning and teaching methods. With this in mind, this paper begins to examine the impact of the learning environment on the student learning experience, specifically focusing on students studying on the Architectural Technology and Management programme at Ulster University. The aim of this study is two-fold: to increase understanding of the impact of learning space layout, by taking a student centered approach; and to gain an appreciation of how technology can impact upon the learning space. The study forms part of a wider project being undertaken at Ulster University known as the Learning Landscape Transition Project, exploring the relationship between learning, teaching and space layout. Data collection was both qualitative and quantitative, with use of a case study supported by a questionnaire based on attitudinal scaling. A focus group was also used to further analyse the key trends resulting from the questionnaire. The initial results suggest that the learning environment, and the technology within it, can not only play an important part in the overall learning experience of the student, but also assist with preparation for the working environment to be experienced in professional life.
