EMLs : case study in distance learning education
After a short characterization of what an educational modeling language should be, we will deal with the respective interest of two EML proposals : one proposed by OUNL (OUNL/EML and IMS/LD which is derived from it) and one proposed by UNED (PALO). We will then identify reasons that lead us to choose OUNL/EML for experimentation in distance learning education in order to model our scenario. Finally we will present some limitations or extensions we have identified.

Organisational patterns for e-learning centres
In this paper we explore the notion of using organisational patterns in educational design for the development of e-learning centres. We are using patterns to discuss some of the key aspects concerning the implementation of an e-learning centre within an institution, with an emphasis on the purposes and pedagogical principles that will help to successfully support such an initiative. The research approach which informed our pattern development work includes use of a qualitative survey of a set o

Learning Object-Oriented Programming
Loud discussions concerning various ways of teaching object-orientation have taken place without much empirical evidence for any position. This paper reports qualitative observations of learning of object-ori-ented programming in an introductory course. The students were found to cope reasonably well with the object-oriented concepts, and they had learnt procedural programming first. However, they modeled the real world domain to be represented in the program by imagination and through coding. T

Working in ToonTalk with 4- and 5-year olds
We aim to find ways, tools and/or techniques that allow children in this age span to use programming language concepts to express rules and play with them. ToonTalk, with its visual, animated environment, and program-by-example methodology, seemed a very nice tool to start with. On this paper, we will present our experience using Portuguese ToonTalk with 7 children (5 were 4-year olds, 2 were 5- year olds), in Vila Real (Portugal) kindergartens, from May to June of 2000.

Semantic Annotation for Learning Material
This paper aims at providing the specification for semantic annotation tools for e-learning. From the specific requirements of annotating learning material, we categorize and evaluate the existing annotation tools, mainly general purpose ones. We illustrate two research prototypes of annotation tools we developed, and evaluate to what extend the specific requirements of annotating learning material are reached by these research prototypes.

2 Summary of Section 4

  1. Gametes are special cells because they contain only one set of chromosomes instead of the more usual two sets.

  2. The chromosome number is halved by meiosis.

  3. The crossing over and random assortment of chromosomes in meiosis produces a unique set of genes in every gamete, and thus in every individual (except for identical twins, who are derived from the same conceptus).

  4. Sperm production involves many rounds of

Social Disparities in Housing and Related Pediatric Injury: A Multilevel Study

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
