Designing a humane multimedia interface for the visually impaired

Whilst graphical user interfaces (GUI) have gained much popularity in recent years, the need of the visually impaired to use applications in a non-visual environment is great. This paper promotes the provision of interfaces that allow users to access most of the functionality of existing GUIs using speech. This has been achieved by the design of a speech control tool that incorporates speech recognition and synthesis into existing packaged software, such as Teletext, the Internet or a word processor. The tool developed has taken the menu structure as a means of demonstrating what is accessible by the use of speech input and output. The tool provides the facility to dump screen text into clipboard and read it out loud. Adapting existing GUI applications in this way requires successful integration of speech, which in turn requires a profound understanding of the medium and the development of human engineering techniques.     

The Relative Interdependency of Colloquial and Mathematical Discourses Regarding the Notion and Calculations of Limit: an Evidence-Based Cross-Cultural Study

This study compares English- and Korean-speaking university students’ colloquial and mathematical discourses on the notion and practice of limit. There exists a lexical discontinuity in Korean with the word limit, since the mathematical word for limit is not commonly used as a colloquial word in Korean, unlike its use in English. This study discusses similarities and differences with regard to ways students in each country use the word limit in colloquial contexts and in mathematical tasks. Data include surveys and interviews, and participants’ discourses, which were analyzed using Sfard’s (2008) discursive framework. Findings indicate that the mathematical discourse of the Korean speakers was structural (i.e. formal or mathematical) and the one for the English speakers was processual. Further, the differences between the US and Korean participants’ use of limit in everyday and mathematical discourses informed the language-dependent properties of school mathematics discourses in terms of word use, routines, endorsed narratives, and visual mediators. This study discusses different discursive needs—linguistically and culturally—to support meaningful mathematical discourses.     

High Quality Preschool Programs: What Would Vygotsky Say?

The paper considers the definition of high quality preschool from a Vygotskian perspective. Similarities and differences in the issues faced in Russia and those in the United States are discussed as background. Three major ideas are considered from the work of Vygotsky and of his students/colleagues, Daniel Elkonin and Alexander Zaporozhets. The first is the Cultural Historical paradigm as the basis for defining development, which emphasizes the importance of underlying cognitive and social-emotional competencies. The second is the idea of "Leading Activity" with dramatic play defined as the leading activity for preschool. The third is the idea of "amplification" or enrichment rather than acceleration of learning. The article ends with a definition of quality based on these three constructs.     

Predicting successful completion using student delay indicators in undergraduate self-paced online courses

Self-paced online courses meet flexibility and learning needs of many students, but skepticism persists regarding the quality and the tendency for students to procrastinate in self-paced courses. Research is needed to understand procrastination and delay patterns of students in online self-paced courses to predict successful completion and retention. This article examines three measures of delay in undergraduate online self-paced courses: the days between registration date and first date of assignment submission (Days to Start), the average days between assignment submissions (Days between Assignments), and total days between registration and completion (Days to Complete). The average length of time between assignment submissions was found to be most useful to predict final letter grade and withdrawal. Students’ consistency and regular work on a self-paced class may be the best strategy for success. Institutions offering self-paced courses should implement strategies to teach students self-regulating behaviors.     

Perceptions of anatomy: critical components in the clinical setting

The evolution in undergraduate medical school curricula has significantly impacted anatomy education. This study investigated the perceived role of clinical anatomy and evaluated perceptions of medical students' ability to apply anatomical knowledge in the clinic. The aim of this study was to develop a framework to enhance anatomical educational initiatives. Unlike previous work, multiple stakeholders (clinicians, medical students, and academic anatomists) in anatomy education were evaluated. Participants completed an eleven-point Likert scale survey written by the investigators. Responses from both clinical educators and medical students at Penn State Milton S. Hershey Medical Center and College of Medicine suggest that medical students are perceived as ill-prepared to transfer anatomy to the clinic. Although some areas of patient management differ in relevancy to anatomical education, there are areas of clinical care which were uniformly ranked as relying heavily on anatomical knowledge (imaging and diagnostic studies, physical examination, and arrival at correct diagnosis) by a variety of clinical specialists. Our results suggest a need for advanced anatomy courses to be taught coincidental with medical students' clinical education. Development of these courses would optimally rely on input from both clinicians and academic anatomists, as both cohorts rated clinical anatomy similarly (P ≥ 0.05). Additionally, we hypothesize that preclinical students' application of anatomy would be enhanced if clinical context was derived from areas of clinical care which rely heavily on anatomy, whereas courses designed for advanced medical students will benefit from anatomical context focused on specialty specific aspects of clinical care identified in this study.     

Professional skills development in a resource-poor setting: the case of pharmacy in Malawi

The dominance of the human capital approach in vocational skills development has been increasingly questioned for being de-humanised and de-contextualised. Contrary to this trend, the discourse in health professional skills development has shown increasing enthusiasm for consolidating this existing paradigm. To debate whether professional skills development should indeed be insulated from such scepticism, this paper examines one strategy adopted by the health professions. Called ‘task shifting’, this strategy involves re-delegating professional tasks to nonprofessional cadres according to a skills-based toolkit. Challenging the context-free approach to using this toolkit, this paper presents ethnographic evidence derived from a case study of pharmacy workforce issues in Malawi. It was found that task shifting was inhibited by a perception barrier about the moral and intellectual superiority of the pharmacists. Pharmacy technicians were judged to be unfit for a professional task because of a perceived lack of professional status, power and ethics. On tracing the origin of the inherent professional prowess assigned to the pharmacists, it was found that professionalism was an ideology borrowed from external sources, inter alia, colonial legacies and global health governance. This study exposes our hidden assumption about an axiomatic transferability of Anglo-American skills development models to a postcolonial, aid-dependent context. This paper therefore suggests redefining this toolkit by bridging health research into dialogue with non-health disciplinary concerns such as postcolonialism and aid-dependence. In conclusion, it argues that professional skills development is context-laden; and in need of a human-centred approach that involves true indigenous participation–challenges not unlike those faced by the vocational skills discourse.     

Spatial pedagogy: mapping meanings in the use of classroom space

The positioning and movement of the teacher in the classroom are fundamental to the pedagogical process. Specific spaces in the classroom take on certain meanings because of the nature of pedagogic discourse that occurs on the site and the positioning and distance of the site relative to the students and the teaching resources. Spatial pedagogy is realised through the patterns of positioning and the directionality of movement, as well as the intersemiotic correspondences in the use of space with other semiotic resources (e.g. language, gesture and teaching materials). This paper investigates the different types of space in the classroom and their associated meanings. It also discusses an approach for annotating the teacher’s use of space, and the usefulness of visualising this annotation through digital graphical methods. The notion of ‘structured informality’ in the classroom is proposed through data analysis of two teachers conducting similar lessons, but with apparently different pedagogical styles.     

International students’ use of social network services in the new culture: a case study with Korean youths in the United States

In the United States, international students, especially from Asia, have reportedly experienced difficulty adjusting to their new life and culture. Little research has been done to understand the role of social network service (SNS)s, including instant messaging, blogs, chatting websites, and email on these students. Korean students are the largest international student group in the United States and were selected for the qualitative case study. Results showed that the participants used SNSs in various ways for their emotional well-being and for academic purposes.     

What (more) can,and should,assessment do for learning? Observations from ‘successful learning context’ in Singapore

Singapore has earned accolades as one of the leading education systems in the world, based on its record in international assessments, including TIMMS and PISA. This has contributed to the entrenchment of ‘assessment’ becoming an institutional authority of standards, teaching (performativity) and classroom learning. It is against, and amidst such contexts, that this article traces how the notion and discourse of formative assessment and Assessment for Learning (AfL) are widely introduced and used formally across all Singaporean schools, particularly after a recent introduction of new ‘Holistic and Balanced Assessment’ policies. We argue that the very institutional authority of successful high-stake examination results, which served as critical standards of performativity of teaching and learning in the classroom, is being challenged. The changing assessment context of Singaporean schools, therefore serves as an interesting case study site for studying how formative assessment and AfL can be adapted and understood when ‘learning’ is already seen to be successful.     

Factors affecting the adoption of social network sites: examining four adopter categories of Singapore's working adults

Adapted from Chang et al.'s (2006) models, this study examines factors that influence adoption and non-adoption of social network sites (SNS) in adopters (Continuers, Discontinuers) and non-adopters (Potentials, Resistors). Chi-square and t-test were used to analyze the survey data of Singapore's working adults and Internet users (N =222). The findings reveal innovation characteristics (relative advantage, compatibility, complexity) and perceived popularity differ significantly in three pairs of adopter categories. Results show Continuers and Potentials are concerned more about image than Discontinuers and Resistors, while technology cluster differs between adopter vs. non-adopter and Continuers vs. Discontinuers. Moreover, the study suggests younger people tend to adopt SNSs, females continue to use SNSs more, and potential SNS users are more innovative. Lastly, a regression model to forecast the adoption of SNSs is proposed in which age, compatibility, technology cluster, and perceived popularity are predictors.
