How are science teachers using their TELA laptop?

The Digital Horizons: Laptops for teachers scheme provides teachers whose schools opt into the TELA scheme access to a laptop for their exclusive use. This paper reports on a three-year evaluation of the impact of the TELA laptops on teachers’ work. The findings of the evaluation suggest teachers are making substantial use of the laptop for tasks such as lesson planning and preparation, reporting to parents and communication with colleagues. Teachers are making some use of the laptop in the classroom for teaching and learning. Science teachers are amongst the most active users of the laptops and the paper details how ongoing access to a laptop changed the way a third year science teacher planned for teaching and subsequently his interactions with students during lessons. Colleagues and the science head of department noted that the teacher provided a role model for what was possible. This case study highlights the importance of leadership and collaboration in supporting the integration of ICT into science teaching and learning

On the testability of WCAG 2.0 for beginners

Web accessibility for people with disabilities is a highly visible area of research in the field of ICT accessibility, including many policy activities across many countries. The commonly accepted guidelines for web accessibility (WCAG 1.0) were published in 1999 and have been extensively used by designers, evaluators and legislators. W3C-WAI published a new version of these guidelines (WCAG 2.0) in December 2008. One of the main goals of WCAG 2.0 was testability, that is, WCAG 2.0 should be either machine testable or reliably human testable. In this paper we present an educational experiment performed during an intensive web accessibility course. The goal of the experiment was to assess the testability of the 25 level-A success criteria of WCAG 2.0 by beginners. To do this, the students had to manually evaluate the accessibility of the same web page. The result was that only eight success criteria could be considered to be reliably human testable when evaluators were beginners. We also compare our experiment with a similar study published recently. Our work is not a conclusive experiment, but it does suggest some parts of WCAG 2.0 to which special attention should be paid when training accessibility evaluator

Arabic language-learning strategy preferences among undergraduate students

This study elicited Arabic students’ perceptions regarding their language-learning strategy preferences (LLSPs). A sample of 120 undergraduate Arabic students participated. Data were collected through a questionnaire and interviews. The findings reveal that students tend to adopt a holistic view of the learning task and relate it to real-life, personal experience. Participants selected interaction with the teacher, speaking, and flashcards as their most preferred application-directed learning strategies. These selections demonstrate that Arabic students desire to be proactive in order to make the language more concrete for them, to enhance their performance, and to develop language skills that will last a lifetime. Whereas advanced level participants preferred interaction with the teacher, speaking, flashcards, and working individually, beginner level participants preferred learning grammar and group work. The empirical evidence from this study could have implications regarding theoretical models of effective Arabic language instruction, Arabic teacher education programs, and curriculum development

On the wings of imagination”: Agnes Giberne and women as the storytellers of victorian astronomy

Agnes Giberne was a “pioneer” of easy to understand astronomy books for children and beginners. She merged fact with fiction to educate her readers about the wonders of the heavens and the religious significance she believed resided there. Employing the dialogue form and the theme of the cosmic journey she encouraged her readers to learn about the sun, moon and planets on “the wings of imagination”. Victorian astronomy was predominantly a male science and astronomical writing operated as chiefly a male genre. Yet, Giberne carved out a place as one of the most popular writers on astronomy in the late nineteenth century, her works appealing across generational, gender and class lines. Giberne’s astronomical writing was shaped by contemporary critical responses to women’s place in astronomical science and the genres acceptable for female authorship. Writing for children, using analogies from botany and being “mindful” of her “catechism”, Giberne stayed within the bounds of Victorian femininity. However, Giberne used her writing on astronomy, not only as an acceptable feminine vehicle for transmitting the facts of astronomical science, but also to show how women, as well as men, could be the storytellers of astronomy

A reflective characterisation of occasional user

This work revisits established user classifications and aims to characterise a historically unspecified user category, the Occasional User (OU). Three user categories, novice, intermediate and expert, have dominated the work of user interface (UI) designers, researchers and educators for decades. These categories were created to conceptualise user's needs, strategies and goals around the 80s. Since then, UI paradigm shifts, such as direct manipulation and touch, along with other advances in technology, gave new access to people with little computer knowledge. This fact produced a diversification of the existing user categories not observed in the literature review of traditional classification of users. The findings of this work include a new characterisation of the occasional user, distinguished by user's uncertainty of repetitive use of an interface and little knowledge about its functioning. In addition, the specification of the OU, together with principles and recommendations will help UI community to informatively design for users without requiring a prospective use and previous knowledge of the UI. The OU is an essential type of user to apply user-centred design approach to understand the interaction with technology as universal, accessible and transparent for the user, independently of accumulated experience and technological era that users live in

Student reaction to parallel hypertext and menu‐based interfaces

It is often necessary to consider the question of what sort of interface is most useful for retrieving information from a particular land of database. A small database of text‐based but multi‐faceted items is used here in order to compare ease and speed of retrieval from two commonly used combinations of interface — HyperCard on an Apple Macintosh and dBase III+ on a PC. For the restricted range of tasks employed here, the latter combination appears to be more acceptable to students with limited computer experience. However, in more general terms, the acceptability of an interface for information retrieval depends on what particular aspect of information retrieval is being emphasized, and what conceptual frameworks students bring to their tasks
