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.     

Developing Well-informed,Critically Thinking,and Active Citizens Through the Connection of Modeling & Simulation and Social Studies Education

While the importance of Science, Technology, Engineering, and Mathematics (STEM) education to address complex world problems, such as global warming, disease, and an increasingly interdependent world economy has led to many educational reform efforts in recent years, other content areas, such as social studies, have unnecessarily become marginalized. As STEM is not a standalone subject area, it serves as a tool to facilitate the learning of a variety of topics and is best served when integrated into all content areas, establishing a collaborative, rather than competitive, culture of content throughout the academic environment. To date, though, this integrated culture has not been realized.     

Supporting learning with interactive multimedia through active integration of representations

When learners explore dynamic and interactive visualisations they are often not able to interact with them in a systematic and goal-oriented way. Frequently, even supporting learners in processes of discovery learning does not lead to better learning outcomes. This can be due to missing pre-requisite knowledge such as the coherent mental integration of the pictorial and symbolic sources of information. In order to support learners in this process, we encouraged them to interactively and externally relate different static sources of information to each other before exploring dynamic and interactive visualisations. We evaluated the benefit of this instructional support in two experimental studies concerning the domains of statistics and mechanics. It revealed that the active integration of static representations before processing dynamic visualisations resulted in better performance and can provide a basis for a more systematic and goal-oriented experimentation behaviour during simulation-based discovery learning.in final form: 16 November 2004     

Impact of science-technology learning environment characteristics on learning outcomes: pupils’ perceptions and gender differences

Science and technology are connected to each other and are mutually inspiring. The science-technology curriculum for junior-high school in Israel suggests that teachers integrate these subjects. In addition, this curriculum calls for infusing thinking competencies into the learning subjects and for implementing alternatives in assessment methods in the classes. The current research included three stages: field research, pilot research and expanded research. In the field research, an intervention program was planned and implemented. The intervention program included a three-year inservice training workshop consisting of 224 hours each year. Quantitative and qualitative tools were used to assess teachers implementation of the intervention program. The findings revealed the characteristics of the science-technology learning environment and various learning outcomes. The pilot research enabled the development and validation of a questionnaire called the Science-Technology Learning Environment Questionnaire (STLEQ). The STLEQ was aimed at assessing teachers and pupils perceptions of learning environment. The conclusions from the pilot research showed differences between teachers and pupils perceptions towards the impact of learning environment characteristics on learning outcomes.In the expanded research, two cohorts of pupils participated, namely, the 2002 cohort (N = 207) and the 2003 cohort (N = 159). These cohorts had studied science-technology in junior-high school. The findings of the expanded research partly match the findings from the pilot research, leading to insight into the pupils perspective of the science-technology learning environment. No gender differences were found in pupils scoring of learning outcomes. On the other hand, boys scored higher than girls on Computer Usage. This research enables researchers and teachers to use the questionnaire in order to investigate pupils perceptions of their learning environment.

Warm elaborated feedback. Exploring its benefits on post-feedback behaviour

Abstract

This study provides evidence on the impact of including warm messages in elaborated feedback. These messages are aimed at the motivational process that can be mobilised by feedback and that which can condition its reception and the way students face the task (post-feedback behaviour). In a task where secondary school students had to learn a new strategy for improving their reading skills in a computer-based environment, we compared the use of elaborated feedback with the use of elaborated feedback enhanced with motivational messages (warm elaborated feedback) and a control condition (without feedback). The results showed that students receiving warm elaborated feedback revisited the text more often than those receiving only the elaborated feedback, and that both groups revisited the text more than the control group. This finding suggests that controlling the motivational aspects in feedback messages may increase the effectiveness of elaborated feedback.

Learning Environments Research,Lifeworld Analysis,and Solidarity in Practice

Learning environments research is generally premised on an assumption that something like an environment independent of the individual can be identified. However, research in many disciplines questions this assumption. I outline here a phenomenological perspective of theorizing the environments in which we act and to which we react, our individual lifeworlds. Lifeworld analysis requires a sense of solidarity. Because it allows an understanding of the world of the Other, it constitutes a lens particularly important and useful in teaching as praxis.

Student and Teacher Perspectives in Computer-Mediated Learning Environments in Teacher Education

Rapid advances in technology, particularly with the Internet, have led to the availability of numerous tools to support teaching and learning. This study involved the use of an Internet application, Connecting Communities of Learners (CCL), in courses for prospective teachers. Unlike earlier studies involving the use of the CCL, the context of this study related to full-time graduate students who used the CCL to augment weekly face-to-face instruction. An interpretive study was undertaken to ascertain student and teacher perceptions of the learning environments associated with the use of the CCL. Through the use of the CCL, students were able to be autonomous in regard to their own learning, co-participate with their peers and the instructor, and establish and maintain a community of learners in which participants could interact with others as co-teachers and co-learners. The CCL was perceived as a useful tool for building learning environments in which all participants can contribute written texts as evidence of what is known and as objects from which others can learn.

Coordinating scaffolds for collaborative inquiry in a game-based learning environment

Collaborative inquiry learning affords educators a context within which to support understanding of scientific practices, disciplinary core ideas, and crosscutting concepts. One approach to supporting collaborative science inquiry is through problem-based learning (PBL). However, there are two key challenges in scaffolding collaborative inquiry learning in technology rich environments. First, it is unclear how we might understand the impact of scaffolds that address multiple functions (e.g., to support inquiry and argumentation). Second, scaffolds take different forms, further complicating how to coordinate the forms and functions of scaffolds to support effective collaborative inquiry. To address these issues, we identify two functions that needed to be scaffolded, the PBL inquiry cycle and accountable talk. We then designed predefined hard scaffolds and just-in-time soft scaffolds that target the regulation of collaborative inquiry processes and accountable talk. Drawing on a mixed method approach, we examine how middle school students from a rural school engaged with Crystal Island: EcoJourneys for two weeks (N=45). Findings indicate that hard scaffolds targeting the PBL inquiry process and soft scaffolds that targeted accountable talk fostered engagement in these processes. Although the one-to-one mapping between form and function generated positive results, additional soft scaffolds were also needed for effective engagement in collaborative inquiry and that these soft scaffolds were often contingent on hard scaffolds. Our findings have implications for how we might design the form of scaffolds across multiple functions in game-based learning environments.
