Printing and screen reading in the medical school curriculum: Guttenberg vs. the cathode ray tube

Abstract

Functions which control access to data in groupware should be designed flexibly by offering different options to end users. However, conflicts might arise among different end users in the process of selecting one of these options. To support users in finding a consensual solution for these conflicts, we propose a metafunction called ‘negotiability’. We propose to define and explore the concept of ‘negotiability’, and discuss its application to access control, concurrency control, and consistency control. We assume that negotiability can play an important role in tailoring these mechanisms and supporting a co-operative use of system's flexibility.     

Recovery and immobilization of lead in cathode ray tube funnel glass by a combination of reductive and oxidative melting processes

Reductive melting treatment has been reported to be an effective method to recover lead from funnel glass in used cathode ray tubes, but a small amount of lead, a potential contaminant, remains in the treated glass. This paper applied a combination process of reductive and oxidative melting to the funnel glass to recover and immobilize lead in the glass. The funnel glass was melted in a lab‐scale reactor changing the atmosphere, and the effects of the temperature and the Na₂CO₃ dosage on the efficiencies of the lead recovery and immobilization were investigated. In the reductive melting, the lead recovery was promoted by increasing the Na₂CO₃ dosage, however the lead extraction from the glass into water and hydrochloric acid was increased. Although the content of lead in the glass after the reductive melting was low, the lead extraction into water and the acid was larger than 0.01 mg‐Pb/L‐water and 150 mg‐Pb/kg‐glass, respectively (Japanese environmental criteria). The lead extraction was decreased by the oxidative melting with SiO₂, Al₂O₃, MgO, and NaNO₃. In the proposed method, metallic lead was recovered from the funnel glass with high lead recovery, and the lead remaining in the glass was immobilized to meet the Japanese environmental criteria.     

The influence of reading speed and line length on the effectiveness of reading from screen

With such a large volume of material accessible from the World Wide Web, there is an urgent need to increase our knowledge of factors influencing reading from screen. We investigate the effects of two reading speeds (normal and fast) and different line lengths on comprehension, reading rate and scrolling patterns. Scrolling patterns are defined as the way in which readers proceed through the text, pausing and scrolling. Comprehension and reading rate are also examined in relation to scrolling patterns to attempt to identify some characteristics of effective readers. We found a reduction in overall comprehension when reading fast, but the type of information recalled was not dependent on speed. A medium line length (55 characters per line) appears to support effective reading at normal and fast speeds. This produced the highest level of comprehension and was also read faster than short lines. Scrolling patterns associated with better comprehension (more time in pauses and more individual scrolling movements) contrast with scrolling patterns used by faster readers (less time in pauses between scrolling). Consequently, effective readers can only be defined in relation to the aims of the reading task, which may favour either speed or accuracy.     

Reading the medical record. I. Analysis of physicians' ways of reading the medical record.

Physicians were interviewed about their routines in everyday use of the medical record. From the interviews, we conclude that the medical record is a well functioning working instrument for the experienced physician. Using the medical record as a basis for decision making involves interpretation of format, layout and other textural features of the type-written data. Interpretation of these features provides effective guidance in the process of searching, reading and assessing the relevance of different items of information in the record. It seems that this is a skill which is an integrated part of diagnostic expertise. This skill plays an important role in decision making based on the large amount of information about a patient, which is exhibited to the reader in the medical record. This finding has implications for the design of user interfaces for reading computerized medical records.     

Computer-based reading and writing across the curriculum: Two case studies of L2 writers

Since the early 1980s, second language (L2) writing specialists have been examining possible roles for computers in L2 writing instruction. How, and to what extent, L2 students use computer for academic literacy purposes beyond the writing classroom, that is, across the curriculum, has not received much attention. Because a common goal of L2 college level writing courses is to prepare students to write in these other domains, an awareness of computer-based literacy activities in non-L2 writing courses is essential to the cause of helping L2 writing instructors connect what students learn in their courses to how they write (and read) in other courses. This paper describes research aimed at contributing to such awareness: a qualitative study of the computer-based reading and writing activity of two undergraduate English as a Second Language (ESL) students beyond ESL writing courses.     

Investigating paper vs. screen in real-life hospital workflows: Performance contradicts perceived superiority of paper in the user experience

IntroductionAll hospitals in the province of Styria (Austria) are well equipped with sophisticated Information Technology, which provides all-encompassing on-screen patient information. Previous research made on the theoretical properties, advantages and disadvantages, of reading from paper vs. reading from a screen has resulted in the assumption that reading from a screen is slower, less accurate and more tiring. However, recent flat screen technology, especially on the basis of LCD, is of such high quality that obviously this assumption should now be challenged. As the electronic storage and presentation of information has many advantages in addition to a faster transfer and processing of the information, the usage of electronic screens in clinics should outperform the traditional hardcopy in both execution and preference ratings.This study took part in a County hospital Styria, Austria, with 111 medical professionals, working in a real-life setting. They were each asked to read original and authentic diagnosis reports, a gynecological report and an internal medical document, on both screen and paper in a randomly assigned order. Reading comprehension was measured by the Chunked Reading Test, and speed and accuracy of reading performance was quantified. In order to get a full understanding of the clinicians' preferences, subjective ratings were also collected.ResultsWilcoxon Signed Rank Tests showed no significant differences on reading performance between paper vs. screen. However, medical professionals showed a significant (90%) preference for reading from paper. Despite the high quality and the benefits of electronic media, paper still has some qualities which cannot provided electronically do date.     

Reading the medical record. II. Design of a human-computer interface for basic reading of computerized medical records.

A user interface for reading the medical record was designed and implemented on a workstation with a 19-inch colour screen. The text is presented on imitations of paper-pages. The pages are organized in bundles which are dynamically connected to scrollable index lists. The turning of pages on the screen is the fundamental concept of the interface. A page can be turned by a mouse-click or by a circular mouse-movement. Elaborated feedback is given to the user in order to provide effortless orientation and navigation. The interface supports the basic ways of use identified in our analyses of reading habits. It also enables human perceptual and cognitive skills to be used. It seems very easy to learn and efficient in use.     

Supporting middle school students' online reading of scientific resources: moving beyond cursory,fragmented, and opportunistic reading

The abundant scientific resources on the Web provide great opportunities for students to expand their science learning, yet easy access to information does not ensure learning. Prior research has found that middle school students tend to read Web‐based scientific resources in a shallow, superficial manner. A software tool was designed to support middle school students in reading online scientific resources through three key strategies: making explicit a skim–read–summarize structure for online reading, using prompts to guide students' reading and foster articulation of thinking, and connecting reading to learning purposes. This study examined the differences between regular and guided online reading performed by eight pairs of sixth graders in a science inquiry project. The students' online reading processes and conversations were captured by a screen‐recording programme. Analysis of 60 h of screen videos showed that the students' online reading in the regular condition was cursory, fragmented, and opportunistic, while the structured online reading was more deliberate, thorough, and purposeful. Overall, the results suggest that middle school students' online reading of scientific resources needs to be guided.     

Supporting secondary school students' reading comprehension in computer environments: A systematic review

This systematic literature review analysed the content, focus, provision, and effects of support (scaffolds) in computer environments with regard to secondary school students' reading comprehension outcomes. The relevant search terms yielded many hits (period 2000–2017); however, intervention studies regarding reading comprehension of expository texts in computer environments seemed to be rather scarce. A careful analysis of these studies revealed that most of them provided cognitive support and some provided metacognitive support. Almost all studies focused on learning products, half of them in combination with learning processes. Most studies provided support in the form of statements, often provided during the task. Both cognitive and metacognitive scaffolds in computer environments produced a positive effect on reading comprehension outcomes. However, only one of the studies provided students with motivational scaffolds. Because the details of the design and content of the scaffolds used in all studies often remained unclear, it was difficult to determine the effectiveness of specific characteristics of scaffolds in computer environments. It is suggested that researchers should be more careful and comprehensive in designing and reporting on research in this area. Recommendations for future research and practical implementations of computer environments are presented.     

The importance of elementary school students’ social chat online: Reconceptualising the curriculum

The Internet is increasingly being used as a tool for communicating and learning in primary schools across many developed and developing countries. The place of social chat as part of online interactions has as yet not been fully recognised as an important component of learning.     

The TRiTS model: teacher roles in introducing digital technology into a school curriculum

The wide use of digital technology for educational purposes opens up some issues regarding its integration within the school curriculum. Our research aims to contribute to the current discussion about how mobile/portable technology can be integrated into formal education. In this perspective, we consider digital technology and media as a potential integral part of school activity that could effectively support educational achievement. However, the way in which it is applied by teachers in a real context can substantially change its impact on effective achievements. In our research, we extensively investigated the role of the teacher in using digital technology for stimulating and prompting classroom activities in class in-line with the school curriculum. In this paper, we first present a model that illustrates the roles of teachers in transforming digital technology as a resource for developing skills as required in educational curricula. The teacher role in introducing technology at school—TRiTS—model has been conceived by combining relevant literature and findings from a case study that we have been running in a primary school over the last 4 years. We then discuss the influence of the different teacher roles on students (their attitude and level of participation), as emerged from our study.

An electromyographic study of a laser pointer-style device vs. mouse and keyboard in an object arrangement task on a large screen

A large body of HCI research focuses on devices and techniques to interact with applications in more natural ways, such as gestures or direct pointing with fingers or hands. In particular, recent years have seen a growing interest in laser pointer-style (LPS) interaction, which allows users to point directly at the screen from a distance through a device handled like a common laser pointer. Several LPS techniques have been evaluated in the literature, usually focusing on users' performance and subjective ratings, but not on the effects of these techniques on the musculoskeletal system. One cannot rule out that “natural” interaction techniques, although found attractive by users, require movements that might increase likelihood of musculoskeletal disorders (MSDs) with respect to traditional keyboard and mouse. Our study investigates the physiological effects of a LPS interaction technique (based on the Wii Remote) compared to a mouse and keyboard setup, used in a sitting and a standing posture. The task (object arrangement) is representative of user actions repeatedly carried out with 3D applications. The obtained results show that the LPS interaction caused more muscle exertion than mouse and keyboard. Posture played also a significant role. The results highlight the importance of extending current studies of novel interaction techniques with thorough electromyographic (EMG) analyses.     

Hybridising GRASP and network flows in the solution of a medical school scheduling problem

This paper tackles the problem of allocating medical students to clinical specialities over a number of time periods. Each speciality is offered by a number of consultant led ??firms?? and the objective is to optimise the schedule in terms of ensuring a broad range of experience for each student, whilst ensuring that every student covers every speciality exactly once without exceeding the number of places available in each firm. The balance between feasibility and optimality is a key issue. We develop a family of GRASP heuristics for the problem, all based on the same local search heuristic, but using a variety of constructions. These use different building blocks, different score functions, and different ways of balancing feasibility and optimality. Empirical tests show that the best heuristic, based on large building blocks facilitated by the use of a network flow model, and enhanced by feedback in the form of partial reconstructions, performs extremely well on real data, and is able to produce acceptable solutions on more challenging artificial problem instances.     

Global citizenship education,school curriculum and games: Learning Mathematics,English and Science as a global citizen

Based on an account of how two classes of primary five students in Singapore engage in the learning of English, Mathematics and Science by playing the role of global citizens, the paper suggests an alternative but realistic approach to teaching global citizenship education. Set against the back story of Atlantis facing ecological, social and cultural decay due to the blind pursuit of prosperity and modernisation by its rulers, each student became a quester called on to save Atlantis. Throughout the mission they were presented with different problems in Atlantis (similar to existing global issues) and were expected to research and suggest solutions to the problems by alone or with fellow questers. These problems were tied to the primary five English, Mathematics and Science curriculum. Through documenting and making sense of these activities via observations, interviews and pre-post questionnaire surveys, the paper shows how the new approach may enhance the learning engagement, academic motivation and social commitments among the students. We also explore the sustainability and scalability of such an approach in the school system and highlight constraints. The paper then draws implications for global citizenship education in schools that include designing a meaningful context for engaged learning in schools with components of global citizenship, developing a research culture in schools as a stepping stone for global citizenship education and building capacity of teachers and school leaders in global citizenship.
