Judging the Constructive Impacts of Communication Technologies: A Business Education Study     

Gregory R. MacKinnon  Conor Vibert 《Education and Information Technologies》2002,7(2):127-135

Through an IBM partnership, Acadia University has the benefit of an infrastructure that places a laptop computer in the hands of some 4000 faculty and students on campus. Coupled with anytime–anyplace campus access to the computer network, the setting offers unique opportunities to study the pedagogical impacts of the use of computers in classroom instruction.University business administration courses have routinely employed case study approaches in the delivery of some course content. The research described follows the use of an elaborate case study communications networking system being used in a business course on competitive intelligence. Though the technology collage allows for certain opportunities to promote quality instruction, not all aspects of technology use were found to be productive. This paper provides an analysis of the appropriateness of technology usage in the context of a single business education course.  相似文献

Practical independent research projects in science: a synthesis and evaluation of the evidence of impact on high school students     

Judith Bennett  Lynda Dunlop  Kerry J. Knox  Michael J. Reiss  Rebecca Torrance Jenkins 《International Journal of Science Education》2018,40(14):1755-1773

Practical independent research projects (IRPs) are a feature of school science in a number of countries. To assess the impact of IRPs on students, a systematic review of the literature was undertaken. Thirty-nine papers met the review inclusion criteria, reporting on work from twelve countries. The review indicates that IRPs are often associated with wider initiatives such as authentic science, problem-based learning, and project-based learning. There is considerable variability in the nature of IRP work in relation to focus, models of provision, assessment, the involvement of external partners such as universities and employers, and funding, and this diversity affects judgements on the quality of the evidence base on impact. The majority of the research reviewed explored areas such as conceptual understanding, motivation to study science once it is no longer compulsory and attitudes to science, and the development of practical skills. Benefits were identified in relation to the learning of science ideas, affective responses to science, views of pursuing careers involving science, and development of a range of skills. Studies focusing on traditionally under-represented groups indicated that such students felt more positive about science as a result of undertaking IRPs. The review findings indicate that further work is needed to enhance the quality of the available evidence, to consider the ways in which IRPs can be validly assessed, to explore more fully the potential benefits for traditionally under-represented groups, and to explore more fully the potential longer-term benefits of participation in IRPs at high school level.  相似文献

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.  相似文献   

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.  相似文献   

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

Yaron?DoppeltEmail author 《Learning Environments Research》2004,7(3):271-293

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.  相似文献
