ICTs and the South African Higher Education Landscape
This report is a mapping exercise, which describes and explores the landscape of ICTs and higher education in South Africa since 2000. Broadly delineating the terrain, the focus is on teaching and learning within higher education. This study sets out to answer five questions: 1. How are ICTs understood and described by practitioners and researchers? 2. What policies and structures for ICTs exist nationally and institutionally? 3. What does the emerging domain of enquiry look like? 4. How do prac
Vers une approche déclarative pour les logiciels de dessins géométriques
Cet article est consacré à la conception d'un environnement d'apprentissage de la géométrie orienté vers la manipulation directe de figures géométriques. À travers deux exemples d'activités, proposées en classe, on distingue les notions de construction géométriques, de spécification, et de manipulation directe. Dans le cadre ainsi défini, nous présentons notre approche. Elle consiste à intégrer des mécanismes et la méthodologie de l'intelligence artificielle dans un logic
Developing Interactive Learning Environments that can be used by all the classes having access to co
Our research team has developed and experimented software for the learning of algebra, named Aplusix, with the idea of being usable and useful for all the classes having access to computers, and of helping teachers to teach the curriculum. In this paper, we list 19 principles that we consider relevant to this goal and we briefly describe the Aplusix system. This system is distributed in France since early 2005 and will be distributed in many countries from 2006. It has proven to be efficient (st
Interdisciplinary approach for the design of a learning environment
This paper presents our interdisciplinary approach for the design of a technology-based learning environment for orthopaedic surgery. We present how the didactical analysis of teaching and learning in workplace gives a framework to build the computational representation of knowledge. This analysis is shown within the context of the apprenticeship of concepts of anatomy and orthopaedic surgery.
Investigating multimodal interactions for the design of learning environments: a case study in scien
This thesis focuses on multimodal interactions for the design of a learning environment. The process of designing such systems involves studying the benefits of multimodal interactions in learning. Therefore, it analyses the structure of the interactive space between the learner and the content to be learnt, and introduces and tests a framework to structure it. It proposes that multimodal interactions can encourage rhythmic cycles of engagement and reflection that enhance learners’ meaning con

Using computers to learn logic: undergraduates' experiences
Learning formal logic can be difficult for many students. This paper describes some ongoing research into a computer program designed to help computer science undergraduates learn the natural deduction style of formal reasoning. Data collection methods included observation and videotaping of workshops, interviews, written tests, surveys, and logging of program usage. The paper focuses on students' experiences using the program to assist proof construction. It was found that videotaping students

Off-Task Behavior in the Cognitive Tutor Classroom: When Students "Game The System".
We investigate the prevalence and learning impact of different types of off-task behavior in classrooms where students are using intelligent tutoring software. We find that within the classrooms studied, no other type of off-task behavior is associated nearly so strongly with reduced learning as "gaming the system": behavior aimed at obtaining correct answers and advancing within the tutoring curriculum by systematically taking advantage of regularities in the software's feedback and help. A stu
Do partners care about their mutual location? Spatial awareness in virtual environments
This paper reports on four experimental studies concerning regard to how people use space so as to solve problems collaboratively in virtual environments. Prior to presenting the results, it summarizes the wide range of literature concerning social uses of spatiality in human interactions. The experiments we conducted revealed that virtual space modifies and improves collaborative processes such as division of labor, grounding, communication, coordination, as well as the performance to the task.
Acid-Base Titration: Analysis of Phosphoric Acid Anodizing Solutions. A Problem-Based Learning Appro
In this paper, the authors have information about a real world situation that can be used as a context to situate the lab and this is the main contribution of the paper. Their collaboration with Delta is an excellent example of using local industry to authenticate the problem. While there are not too many details about the way problem based learning is implemented, educators looking for a PBL scenario for acid base titrations and atomic absorption will find this a useful paper.
Health Disparities among Racial and Ethnic Groups in Rhode Island
The health of racial and ethnic minority populations has been a focus of public health for many years, due to the disparities in health status, exposure to health risks, and access to health care that are revealed when these populations are compared to the White, non-Hispanic population. At the national level, the impact of poor health on the quality and length of life for minority citizens was considered to be so fundamental that one of the three overarching goals of Healthy People 2000 was to
Social Disparities in Housing and Related Pediatric Injury: A Multilevel Study
Objectives. We conducted an ecologic analysis to determine whether housing characteristics mediate the associations between concentration of poverty and pediatric injury and between concentration of racial minorities and pediatric injury and whether the association between housing conditions and pediatric injury is independent of other risks. Methods. We created a hierarchical data set by linking individual-level data for pediatric injury with census data. Effect sizes were estimated with a Poi
A methodological note on modeling the effects of race: the case of psychological distress
Psychological distress is an important indicator of the mental well-being of the population. Findings regarding racial differences in distress are inconclusive but may represent an important pathway through which disparities exist across a number of physical health outcomes. We used data from the 1994 Minority Health Survey, a nationally representative multiracial/ethnic sample of adults in US households, to examine racial/ethnic differences in psychological distress (n = 3623). Our primary stud
The Health Impact of Resolving Racial Disparities: An Analysis of US Mortality Data
The US health system spends far more on the “technology” of care (e.g., drugs, devices) than on achieving equity in its delivery. For 1991 to 2000, we contrasted the number of lives saved by medical advances with the number of deaths attributable to excess mortality among African Americans. Medical advances averted 176 633 deaths, but equalizing the mortality rates of Whites and African Americans would have averted 886202 deaths. Achieving equity may do more for health than perfecting the te
Racial Differences in 30-Day Mortality for Pulmonary Embolism
Objectives. Previous studies reported a higher incidence of in-hospital mortality for Black patients who had pulmonary embolism than for White patients. We used a large statewide database to compare 30-day mortality (defined as death within 30 days from the date of latest hospital admission) for Black and White patients who were hospitalized because of pulmonary embolism. Methods. The study cohort consisted of 15531 discharged patients who had been treated for pulmonary embolism at 186 Pennsylv
Iron Hill School: An African-American One-Room School
is a curriculum-oriented guide focusing on a school constructed in 1923 in a rural area of northern Delaware, one of more than 80 schools for African-American children built between 1919 and 1928 as part of philanthropist Pierre Samuel du Pont's Delaware experiment. The site shows photos, maps, and diagrams about the school itself and suggests student activities ranging from philanthropy to school architecture.
Holding a poetry slam
Introducing students to "the competitive art of performance poetry" builds enthusiasm for literature among even reluctant readers. This article explains how a high school in Cleveland County, North Carolina, held its first poetry slam.
