This paper investigates the role of government R&D subsidy programs in stimulating knowledge spillovers. R&D subsidies are an effective public policy instrument when knowledge spillovers exist yet ex ante it is difficult to identify projects that have the greatest potential to increase innovation and economic growth. This paper derives a set of project and firm attributes that the literature finds generate knowledge spillovers and uses data on project proposals to estimate the degree to which a government R&D program conforms. We find that projects that were awarded R&D subsidies were more likely to have attributes such as participation in new research joint ventures and connections to universities and other firms. Following the post-award activities of firm, we find that receipt of a government R&D subsidy increased the funding from other sources when compared to firms that were not awarded funding. 相似文献

This study examined the influence of spending time outdoors on young children’s physical and socioemotional development. We observed preschoolers’ activities in two naturally provisioned outdoor environments over the course of one year. Eleven preschoolers were videotaped continuously for 16 days at a local river and 9 days at a creek adjacent to the school. In addition to the quantitative analyses of children’s behaviors, a case study of three children’s experiences over the course of the year was conducted. Both the river and the creek settings encouraged a multitude of physical and play behaviors with similar types of affordances, including flat surfaces for running, rocks for climbing and jumping off, and water for exploration and play, but the wilder environment (river) afforded more risk and personal challenges. Observations of children’s motor activities, play and responses to challenging environmental features supported the importance of accumulated experience and social context for the development of confidence in the face of risk, individual exploration and positive social support and engagement with peers. 相似文献

The purpose of this qualitative study is to investigate the mathematics educational experiences of Black undergraduate students majoring in science, technology, engineering, and mathematics disciplines at the University of Virginia. Using Murrell's (2009) situated-mediated identity theory as the theoretical framework, this study examines factors that influence the construction of mathematics identities of these students. Findings indicate that race significantly influenced the educational experiences of these students and, consequently, the construction of their identities as mathematics learners and doers. 相似文献

School psychologists are increasingly engaged in service provisions for students eligible for special education services under the eligibility category of autism, including conducting school‐based assessments and evaluations. Evaluations occur for a variety of reasons such as special education eligibility decision‐making, treatment and intervention planning, and progress monitoring. Publications in school psychology journals emphasizing autism spectrum disorder (ASD) assessment and evaluation are vital to quality training and practitioner utilization of quality practices. In the current study, researchers conducted a systematic review of publicaftions in 10 school psychology journals from 2007 to 2017 to assess the current state of ASD assessment and evaluation research in the field of school psychology. Implications for researchers, trainers, and practitioners are discussed. 相似文献

ABSTRACT A constructivist approach to teaching and learning holds that the learner, through interaction and experience with an object or process, creates knowledge. Instruction based upon constructivist theory places the student at the center of the learning environment, while the instructor serves as a guide or facilitator. In direct contrast, traditional learning places the learning in a more passive role, simply mirroring or reproducing knowledge that was provided by the instructor. Constructivist theory has enjoyed a certain level of popularity in higher education as emphasis has shifted from a pedagogical framework to a more andragogical (i.e., adult and learner-centered rather than instructor-lead) one. Emphasis upon teaching critical thinking skills seems a natural fit with a constructivist-based approach to learning. Critical thinking involves the conceptualization, analysis, synthesis, evaluation, and ultimate application of information so that the learner may reach conclusions or form independent judgments based upon what the learner has experienced combined with previous knowledge. The teaching of critical thinking skills using a constructivist-based approach in the field of online library instruction would be an effective means of reaching the large percentage of learners who do not participate in traditional face-to-face bibliographic instruction sessions. This is further supported by the Association of College and Research Libraries' Information Literacy Standards for Higher Education. This article will provide theoretical and philosophical arguments for constructivist-based approaches to teaching critical thinking skills online using online technologies. 相似文献

Concentrating the attention on one aspect makes it leap into the foreground and occupy the square, just as, with certain drawings, you have only to close your eyes and when you open them the perspective has changed. (Calvino, 1983, p. 7) 相似文献

Ethics education in criminal justice programs has increased in popularity, but instructors sometimes struggle to teach ethics in such a way that students retain what they have learned and apply ethical principles in the criminal justice field upon graduation. The current research highlights that there are several benefits of presenting ethical dilemmas to students through popular movies such as Mississippi Burning and Road to Perdition. Compared to the control group (Section A) that was taught in a traditional lecture format, students who were required to identify ethical dilemmas in movies (Section B) were more likely to understand the complexities of such situations, to rate unethical behavior properly, and to see how ethical principles could be applied to their everyday lives. 相似文献
