In France, the newly designed life and earth sciences programs for the Première Générale (second year of lycée) now include a segment dedicated to ecosystem services. The primary objective is to transition from an anthropocentric approach to an ecocentric approach, integrating the notion of ecosystem services (ES). Our article conducts an epistemological examination of the ES concept, scrutinizing its definition, the array of examples and services, the human role in the environment, monetization, and connections to environmental ethics. The analysis was conducted using a corpus comprising life and earth sciences curricula, textbooks, and online resources, which unveiled diverse examples and materials pertaining to ES. The ensuing discussion emphasizes the need to embrace uncertainty and complexity in order to transcend a positivist rationalization of the human-nature relationship. [ABSTRACT FROM AUTHOR]

This paper investigates the presence (or absence) of Ely's (1999) conditions for implementing innovation in a rural context in the province of Quebec (Canada). The innovation, namely the Remote Networked School (RNS) initiative, is designed to bring new technology tools to enrich the learning environment of students and diminish teachers' isolation in the smallest and most remote schools of the province. The study presents a discourse analysis of four major stakeholder groups of the RNS initiative over three years. The qualitative analysis was designed to identify: 1) the conditions for innovation that were most present in stakeholder discourse over the years; 2) the indicators that strengthened the conditions for innovation presence or absence; and finally, 3) certain variations occurring during the adoption/implementation years of the RNS initiative. This paper reconfirms the adequacy of Ely's model as an effective framework for understanding and monitoring ICT-based systemic teaching and learning innovations such as the province-wide RNS initiative in Quebec.

This article describes the just-in-time online professional development offered to teachers in the Remote Networked Schools (RNS), a systemic initiative funded by the Quebec Ministry of Education (Canada), which aims at enriching the learning environment of small rural schools with the use of information and communication technologies (ICTs). The design experiment method studies the activity identified and the types of professional development offered by a university-based intervention team (UBIT) over six years of deployment.

Remote Networked Schools (RNS) is an initiative by the Quebec Ministry of Education, Leisure and Sports (MELS) to investigate solutions that the use of information and communication technologies (ICT) can offer for the preservation of small rural schools in Quebec, Canada. The implementation of RNS mobilized then--as it still does now--the local capacity for innovation of all the stakeholders involved in this networking effort to improve learning. Building on Donald P. Ely's work (1990; 1999), this paper presents the results of an investigation of the RNS educational stakeholders' perceptions of the importance of the conditions that facilitate the implementation of educational technology innovations for the success of RNS in their locations.

This research paper describes the use of computer mediated conferencing (CMC) to support the teaching of biology to undergraduates. The use of this pedagogical innovation was a first-time experience for both the instructor and his students. The objectives of this project were to increase students' active participation, to facilitate collaborative knowledge building, and to enhance the use of the scientific approach in problem-solving activities. The data indicate that some positive results were achieved for each objective. The use of online computer conferences shows a lot of promise when it is based on reflection, problem-solving, collaborative learning and knowledge building. Internet conferencing tools support students as they reflect and work together and open doors to numerous new educational experiences for both the students and the professors.

This study addressed computer-supported collaborative scientific inquiries in remote networked schools (Quebec, Canada). Three dyads of Grade 5-6 classrooms from remote locations across the province collaborated using the knowledge-building tool Knowledge Forum. Customized scaffold supports embedded in the online tool were used to support student understanding and practice of an authentic inquiry process. The research studied how the use of the scaffolds could help students to understand and put into practice an authentic inquiry process. Students created notes and used the scaffolds to support their inquiry process; however, without sufficient direct teacher modeling, coherent use of the scaffolds stayed low across activities. Pre- and posttest results show that the students gained a better understanding of the inquiry process, but low posttest scores suggest further need for direct teacher modeling of the inquiry process during science instruction.

Education research has shown the importance of helping students develop comprehension skills. Explanation-seeking rather than fact-seeking pedagogies have been shown to warrant deeper student understanding. This study investigates the use of Knowledge Forum (KF) in K-6 classrooms (n = 251) to develop students' explanation skills. To this end, we conducted pre- and post- activity interviews with students who used KF to investigate various topics. Their online collaborative discourse was also analyzed. Our results show that: 1) students' explanations improved significantly between pre- and post-activity interviews, 2) active KF users scored higher than less active users on the post-activity interviews, and 3) students who had the best written explanations on KF scored much higher on the post-activity interviews even when they had scored much lower than less active students in the pre-activity interviews.

This article describes in detail a conversation analysis of conceptual change in a computer-supported collaborative learning environment. Conceptual change is an essential learning process in science education that has yet to be fully understood. While many models and theories have been developed over the last three decades, empirical data to support them are scarce. The present paper aims to provide such evidence. To this end, the article first reviews seven proposed models of conceptual change before it recalls the main ideas behind the two different positions on conceptual change, the pieces (diSessa 2008) versus coherence (Vosniadou et al. 2008) positions. Then, the article presents and discusses how a close discourse analysis of asynchronous collaborative conversations between grade 5 and 6 students on buoyancy and relative density provides further empirical evidence of the knowledge in pieces position.
