Despite a rise in the use of handheld computers in classrooms, meaningful learning with personal digital assistant (PDA) technology remains poorly studied. We report results from an evaluation of customized handheld data collection software, the BioKIDS Sequence, which was used during an 8-week biodiversity curriculum unit by 5th and 6th grade students in southeastern Michigan. We provide new information on design decisions and usability of our customized software; discuss learner use and preferences; and report rates of data accuracy. Most students were able to enter simple animal observations using an icon-driven, largely linear interface. The interface helped expand the types of data students were aware of, and allowed them to view and review their entries and flag them as uncertain, factors important in supporting accurate data collection. Other BioKIDS research indicates students were subsequently able to see simple patterns in their data to guide the formulation of future hypotheses, questions, or conclusions. The BioKIDS Sequence and PDA technology therefore represent a meaningful use of technology to support scientific reasoning. 相似文献

The paper draws upon a national study to analyze two issues relevant to the future effectiveness of the American agricultural technology system: (1) linkages between research and technology transfer activities; and (2) relationships between the public and private sectors. Increased commitments to basic research by the US Department of Agriculture and the state agricultural experiment stations have served to exacerbate existing strains between research and technology transfer functions and units. Both the feasibility and desirability of having USDA's Agricultural Research Service simultaneously seek to strengthen its basic research capabilities and its commitment to technology transfer have been questioned. Within the landgrant universities, multiple pressures have served to attenuate traditional ties among agricultural researchers, extension specialists, and county extension agents.Private sector activity in agricultural research and the provision of technical information has increased following the expansion in the domains of knowledge over which firms can establish property rights and the concentration of production in a smaller number of economic units. Adjustments in the activities of the public sector in response to these changes can be seen. Still, the optimal mix of public-private sector activities in both research and technology transfer has yet to be fully analyzed. Current analyses (and public policy) are excessively constrained by the “property rights” approach to technological change. 相似文献

The Council of State Governments was created over fifty years ago to serve as an information resource for state officials. The Council has been an active information provider over the years and is now entering a new phase which includes the development of a national state government information database and the creation of a state government research institute. 相似文献

A major issue confronting educators is the extent to which they wish to conform to so-called paradigm shifts in teaching and learning. In the contemporary world of tertiary education these shifts embrace both pedagogy (from instructivist to constructivist) and technology (from classroom to online). As teachers and learners are faced with the potential of these new learning environments, the extent to which learning outcomes are achieved remains a high priority and subject to a wide range of evaluation strategies. Conventionally, evaluation has been positioned at the end of the instructional development cycle, to assess first whether or not the creative effort achieved the original product goals and second whether or not the desired learning outcomes were realized. In the context of online teaching and learning environments, however, the level of understanding teachers, learners and developers have of the medium can impact the ultimate effectiveness of the product. This paper articulates an additional dimension to post-development evaluation processes in proposing proactive evaluation, a framework that identifies critical online learning factors and influences that will better inform the planning, design and development of learning resources. This notion of proactive evaluation advocates resource development being undertaken where all planning activities are assessed against the evaluation criteria that would normally be applied during formative assessment. By performing these evaluation checks proactively, online learning resources will, in principle, work first time as all relevant factors and issues will have been considered and resolved. More importantly, for those participants who are new to online environments, proactive evaluation will perform a scaffolding and professional development role by enhancing online teaching or learning competencies. 相似文献

Recent studies have analyzed the cognitive demands of solving problems in genetics, focusing primarily on the Piagetian schemas of combinations, proportions, and probability. Based on data from these primarily correlational studies, some authors have argued for the elimination of classical genetics from the high school curriculum. The critical review of the literature presented in this article reaffirms that formal-operational thought is conducive to successful genetics problem solving. The weight of the evidence to date, however, does not support the position that formal operational thought is strictly required for solving typical genetics problems. Arguments are therefore presented in support of the inclusion of genetics and genetics problem solving in high school biology. Implications of this analysis for the selection of appropriate content, problems, and instructional techniques for genetics instruction for nonformal students are presented. 相似文献

- 170 early career researchers interviewed three times over 2 years, have uniquely contributed towards a stress test of scholarly communications and cracks have been identified.
- The perfect storm created by the convergence of millennial values and the pandemic appears to have fast-forwarded the cracking process, perhaps, for the good.
- The cracks in question are: (1) peer review; (2) reputational assessment; (3) unethical/questionable practices; (4) collaboration; (5) networking.
