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.     

Characterizing cross-professional collaboration in research and development projects in secondary education

Collaboration between practitioners and researchers can increasingly be observed in research and development (R&D) projects in secondary schools. This article presents an analysis of cross-professional collaboration between teachers, school leaders and educational researchers and/or advisers as part of R&D projects in terms of three dimensions: reasons for collaboration, the division of roles and tasks, and the communication structure. Data were collected in interviews with participants from 12 Dutch projects, from documents and from meetings with participants. The results show that the parties involved can have the same reasons for cross-professional collaboration but that the external educational experts may also have additional objectives. Roles and tasks were divided in different ways, depending on who directs and guides the research and development, and whether teachers were involved as teacher researchers in the project. The communication structure appeared to be linked to the division of roles and tasks, but also to the number of participants in the project. The three dimensions proved to be valuable viewpoints to study cross-professional collaboration in R&D projects in Dutch secondary education. Furthermore, we distinguished four types of cross-professional collaboration in R&D projects. These types differ in the extent to which the school or the external party direct and guide the project: (a) School-directed collaboration; (b) School- and researcher-directed collaboration; (c) School- and adviser-directed collaboration; (d) Researcher-directed collaboration. Our findings can support participants to consciously choose a particular type of cross-professional collaboration that fits their purposes and specific situation.     

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.

我国科研项目负责人胜任特征研究成果的计量学分析

采用文献计量学的方法,从论文数量、研究方法、研究主题三个维度对我国科研项目负责人胜任特征研究成果进行了描述统计和内容分析,发现该领域的研究成果呈现以下三个特点:(1)研究数量呈波动中上升的态势;(2)研究方法以质性研究为主,质性与量化研究呈现不平衡性;(3)研究主题将科研项目负责人分为学术型、领导型、管理型和混合型四种类型。而后,采用内容分析法对研究文献进行深入分析,发现科研项目负责人的胜任特征有四类,即基础性胜任特征、学术性胜任特征、领导性胜任特征和管理性胜任特征。
