Contributions of Cooperative Education in Preparing At-Risk Students for Post-High School Transition
Work-based learning interventions, particularly cooperative education, are a viable way to support the post-high school transition process, enhance work-related cognitive development, and increase the occupational engagement of at-risk youth. Using propensity score matching to analyze data from the Educational Longitudinal Study of 2002 (ELS:2002), the impact of participation in cooperative education on two indicators of postsecondary transition readiness, including postsecondary education plans right after high school and importance placed on work, were examined for students deemed at risk of high school failure. Participation in cooperative education had a significant positive effect on at-risk students' postsecondary education plans right after high school. However, no significant effect was detected for the importance students placed on work. 相似文献

Despite the existing challenges in the capital market, technological and market uncertainties, the current business environment may be fertile for innovative firms that could find affordable and scalable clean technology innovations. Navigating innovation management process for any clean technology project is a practical issue that requires attention of financial and non-financial factors affecting technology development and deployment. Such endeavor has precipitated many of the complex questions involved with clean technology industry. This article surveys literatures on resource-based view of the firm, operations management, innovation and technology management, and clean technology. The article identifies key drivers – operations, market and regulatory – of clean technology projects, and further demonstrates their interrelatedness within a comprehensive integrated conceptual framework of development and deployment. This integrated framework contributes to our understanding of innovation management process for clean technology firms, including supply and demand sides. 相似文献

State Dependent Riccati Equation (SDRE) methods have the considerable advantages over other nonlinear control methods. However, stability issues can be arisen in SDRE based control system due to the lack of the global asymptotic stability property. Therefore, the previous studies have usually shown that local asymptotic stability can be ensured by estimating a Region of Attraction (ROA) around the equilibrium point. These estimated regions for stability may become narrow or the condition to keep the states in this region may be very conservative. To resolve these issues, this paper proposes a novel SDRE method employing an update algorithm to re-estimate the ROA when the states tend to move out of the stable region. The tendency is checked using a condition which is developed based on a new theorem. The theorem proves that it is possible to redesign the previous ROA with respect to the current states lying close to its boundary for ensuring the “non-local” stability along the trajectory without the need of solving SDRE at each time instant, unlike the standard SDRE approach. Therefore, the new theorem is now able to enhance the stability of the SDRE based closed-loop control system. The feasibility of the proposed SDRE control method is tested in both simulations and experiments. A validated 3-DOF laboratory helicopter is used for experiments and the control objective for the helicopter is to realise a preplanned movement in both elevation and travel axes. The results reveal that the proposed SDRE approach enables the controlled plant to track the desired trajectory as satisfactorily as the standard SDRE approach, while only solving SDRE when needed. The proposed SDRE method reduces the computational load for practical implementation of the control algorithm whilst ensuring the stability over the operational region. 相似文献

It is important for teachers of mathematics to know how pupils react to certain mathematical situations and what these reactions imply, in order to design more effective instructional environments based on their learning needs. This study reports the development processes of a digital learning tool (Learning Tool for Elementary School Teachers (L‐TEST)) that shows children's mathematical thinking for the ages of 4–11 years across certain problem situations. L‐TEST is designed as a support tool to be used in teacher education. A case‐based instructional model was used in designing the instructional tool. Video recordings were digitised to provide a rich environment where learners observe exemplary cases. These exemplified videos included children's mathematical development in the subjects of numbers and shapes, combined with discussions in line with the current research findings. Finally, a usability test for the learning tool was carried out. 相似文献

A study is presented that explores how students’ knowledge structures, as related to the scientific method, compare at different student ages. A word association test comprised of ten total stimulus words, among them experiment, science fair, and hypothesis, is used to probe the students’ knowledge structures. Students from grades four, five, and eight, as well as first-year college students were tested to reveal their knowledge structures relating to the scientific method. Younger students were found to have a naïve view of the science process with little understanding of how science relates to the real world. However, students’ conceptions about the scientific process appear to be malleable, with science fairs a potentially strong influencer. The strength of associations between words is observed to change from grade to grade, with younger students placing science fair near the center of their knowledge structure regarding the scientific method, whereas older students conceptualize the scientific method around experiment. 相似文献

高校党内基层民主建设的发展离不开强劲动力,动力主体又在诸多因素作用下影响着民主前进的步伐。动力机制单一运行,行政制度无确切落实,领导干部独揽大权,党员教师民主意识淡薄,成为民主良性成长的动力阻碍。这使得高校民主需通过党性培育,权利落实,监督核查,确保民主建设有序推进。 相似文献
