Fostering Distributed Science Learning Through Collaborative Technologies

TACTICS (French and Spanish acronym standing for Collaborative Work and Learning in Science with Information and Communications Technologies) is an ongoing project aimed at investigating a distributed community of learning and practice in which information and communications technologies (ICT) take the role of collaborative tools to support social construction of knowledge. This community is composed of researchers, graduate students, and high-school teachers and their students, from six schools and four universities in Canada and Mexico. It set out in fall 2000 to develop a community around the general topic of integrating concepts in science school subjects. Once a prototype community is established, it can become a terrain where different aspects could be studied. Subsequently, researchers could gradually take a back seat allowing as well as ensuring the autonomy of the school members involved and, thereby, the viability of the learning community. The set up of the proposed prototype distributed science learning community was therefore an essential yet far from trivial first step. This paper discusses the process of setting up the community and the lessons learned.     

“I don’t think that word means what you think it means”: A proposed framework for defining learning communities

In this paper we address the obfuscation surrounding the concept of learning communities by operationalizing community according to four characteristics that serve as boundaries for defining a community: access, relationships, vision, and function. Although these community boundaries sometimes overlap, they represent distinctive features of possible community structures. In addition to defining and discussing learning community boundaries, we share insights for researching learning communities. We believe a clearer understanding of how to define learning communities can assist scholars and practitioners in cultivating and studying these communities.     

Increasing Situational Interest in the Classroom

This paper explores three ways to increase situational interest in the classroom. Situational interest is defined as temporary interest that arises spontaneously due to environmental factors such as task instructions or an engaging text. We review the history of interest research and summarize recent empirical work. We describe three ways to increase interest based on offering meaningful choices to students, selecting well-organized texts that promote interest, and providing the background knowledge needed to fully understand a topic. We conclude with six specific suggestions for increasing situational interest in the classroom.     

Talk about texts: reading as a social event

Drawing on anthropological evidence that interactions with texts are often mediated through oral language practices and Vygotsky's ideas about the primacy of social dialogue for individual intellectual development, the authors argue that children's informal talk about both electronic and printed texts throws new light on the reading process as a whole. They analyse children's talk about a school library book, a piece of graffiti, a television programme and a film to show how readings are shaped by the social organization and personal relationships of the readers, whether in curriculum activities, friendship groups or at home in the family. Readings are constructed, contested and negotiated through talk at the point where texts are first calculated and reshaped again when they are jointly recalled. Talk also helps to construct the text's legitimate audience and the reader's position within it.     

The influence of feedback of diagnosis and executive function skills on rates of false positive and false negative outcomes for ADHD

This study examined executive function (EF) skills and self-reported symptoms of ADHD. EF skills were measured to determine whether skills were different between groups that reported clinical levels of ADHD symptoms (clinical group) and nonclinical levels of ADHD symptoms (nonclinical group). EF skills in the nonclinical group were also investigated to determine whether differences existed for those who received false positive and negative feedback about an ADHD diagnosis. Results indicated statistically and clinically significant differences in EF skills between the clinical and nonclinical group. Participants in the nonclinical group who reported elevated scores on the ADHD screener after receiving false positive feedback had statistically significantly different EF function scores, but not clinically significant scores, compared to the participants in nonclinical group who received negative feedback.     

The Structure of Events and Event Representations: A Developmental Analysis

In this study, we investigated how the temporal order and variability of events influence 3- and 5-year-old children's developing event representations. Children participated in 3 different events: a logical-invariant (making fundough), a logical-variable (shape collage), and an arbitrary-invariant (sand play) event. At each age, half of the children experienced the events once prior to recalling the events both verbally and behaviorally; the other half experienced the events 4 times, recalled the events verbally after each experience, and behaviorally reenacted the events only after the last experience. Children verbally recalled more and organized their recall better for the logical events than for the arbitrary event, and these differences remained stable with increasing experience. The sequencing of behavioral recall was also more accurate for the logical events than for the arbitrary event across age and condition, but amount of recall did not differ, with one exception. 3-year-old children in the single experience condition recalled less about the variable event than the invariant events. The results indicate that both the structure of the event and children's representational capabilities influence children's developing representations of events.     

Designing Training for Global Environments: Knowing What Questions to Ask

As instructional design professionals are being asked more frequently to develop interventions for global environments, they must account for many complex intercultural communication and corporate globalization strategy variables. Simple rules of etiquette and stereotypes about particular cultures are tempting but dangerous assumptions upon which to base the design and delivery of training for multicultural learners. On the other hand, a full understanding of the subtle cultural differences that could impact global training is beyond the expectations to which instructional designers could reasonably be held. A more sensible approach than trying to know all the answers is knowing what questions to ask in the needs analysis and assessment phases. Based on a synthesis of literature and instantiated by several short examples, a framework for identifying important issues for instructional design and delivery in global settings is presented.     

The information requirements and information-seeking behaviours of health and social care professionals providing care to children with health care needs: a pilot study

OBJECTIVES: The objectives of this work were to identify the sources of information currently received, information-seeking behaviours, information requirements and preferences for future information provision amongst health and social care professionals providing care to children with health care needs. METHODS: Data were collected using a cross-sectional postal questionnaire survey. RESULTS: A wide range of information resources was reported as being available to professionals. However, a large proportion of respondents found it necessary to perform additional searches for information, suggesting that current resources were not satisfying their needs. The majority of professionals reported a preference for electronic formats, whilst a smaller proportion preferred hard copy materials. Participants promoted the use of informal networks as a means of support and exchange of information. CONCLUSION: Supplementing the information that is provided in electronic and hard copy formats, by enhancing informal networks, may be the most effective way of meeting the information needs of this group of professionals.
