Reforms in undergraduate engineering curriculum to produce engineers with entrepreneurial skills should address real-world problems relevant to industry and society with active industry support. Technology-assisted, hands-on projects involving experimentation, design simulation and prototyping will transform graduates into professionals with necessary skills to create and advance knowledge that meets global standards. To achieve this goal, this paper proposes establishing a central facility, ‘Centre for Engineering Experimentation and Design Simulation’ (CEEDS) in autonomous engineering colleges in India. The centre will be equipped with the most recent technology resources and computational facilities where students execute novel interdisciplinary product-oriented projects benefiting both industry and society. Students undertake two projects: a short-term project aimed at an engineering solution to a problem in energy, health and environment and the other a major industry-supported project devoted to a product that enhances innovation and creativity. The paper presents the current status, the theoretical and pedagogical foundation for the centre's relevance, an activity plan and its implementation in the centre for product-based learning with illustrative examples.  相似文献

The goals were to (a) replicate the findings of previous research with regard to the Consultee/Teacher Version of the Interpersonal Power Inventory (IPI), and (b) advance the literature by examining IPI scores about a current consultation relationship. Sample 1 included 99 elementary school teachers (44.4% Hispanic) who completed the IPI. Results replicated Erchul et al. Sample 2 (N = 37; 45.9% Hispanic) represented a subset of Sample 1 who participated in a consultation project and completed the IPI about influence in their current consultation relationship. The results advance the literature by offering evidence for convergent and predictive validity of the IPI soft power bases. Teachers who reported being influenced by soft power strategies experienced greater change in their behaviors and their students’ behaviors than those who reported being not influenced by such strategies. Implications for research and practice in school consultation are discussed.  相似文献

The most significant change to impact the pedagogy of criminal justice students in recent years has been the development of online classes. Online coursework is now a commonly accepted method of accessing criminal justice students and the sustained growth in online classes is expected to continue in the future. However, there is currently a lack of research that focuses on online classes in criminal justice. In response, we present and assess the modest literature regarding criminal justice online classes and highlight important themes. This leads into a presentation of important considerations along the following pedagogical continuum: Planning the online course (i.e. asynchronous timing, technological developments), implementing the online course (i.e. maintaining an online presence, managing student interactions and expectations), and identifying effective means to measure learning outcomes (i.e. measuring success, quality matters). Policy implications for online coursework that are likely to impact future criminal justice educational practices are then discussed.  相似文献

Research Findings: Public policy has increasingly focused on expansion of preschool access for underserved students and systematic evaluation of preschool quality and students’ readiness for school. However, such evaluation is limited by a lack of thoroughly validated assessments for use with preschool populations. The present study examined the measurement and structural invariance of the Kindergarten Student Entrance Profile (KSEP) across kindergarten and prekindergarten groups to evaluate its potential use across developmental groups. Participants included 522 kindergarten and 548 prekindergarten students in central California. Invariance was tested by fitting a series of multiple-groups confirmatory factor analysis models with parameter constraints across groups. Results indicated that measurement and structural parameters of the KSEP were invariant across kindergarten and prekindergarten groups. Prekindergarten means on both Social–Emotional Readiness and Cognitive Readiness were significantly lower than kindergarten means. Practice or Policy: These results suggest that the KSEP may potentially be used with prekindergarten students to assess school readiness and inform intervention before kindergarten entry.  相似文献

This article provides a comparative analysis of accessibility of higher education across Russian regions in terms of the following three factors: the availability of admission opportunities; financial affordability; and geographic accessibility.

The study will be of interest to government agencies in higher education at various levels, analysts and researchers, as well as a wide range of readers focused on regional differences in higher education systems and policies.  相似文献

When implementing environmental education and interventions to promote one pro-environmental behavior, it is seldom asked if and how non-target pro-environmental behaviors are affected. The spillover effect proposes that engaging in one behavior affects the probability of engagement or disengaging in a second behavior. Therefore, the positive spillover effect predicts that interventions targeting one specific behavioral have the capacity to promote non-targeted and/or future pro-environmental behaviors. However, the negative spillover effect predicts that engaging in a first pro-environmental behavior will prevent or decrease a second pro-environmental behavior. Since the theoretical and empirical basis for positive and negative spillover effects are not sufficiently understood, the present paper (1) suggests a distinction between behavioral, temporal, and contextual spillovers (2) reviews the existing spillover research literature across a variety of environmental domains, (3) presents potential moderators governing the direction of spillover effects, and finally (4) discuss techniques to promote pro-environmental spillovers.  相似文献

Reported are the results of a multiyear study in which reading comprehension and writing were integrated within an in-depth science instructional model (Science IDEAS) in daily 1.5 to 2 h daily lessons on a schoolwide basis in grades 3–4–5. Multilevel (HLM7) achievement findings showed the experimental intervention resulted in significant and consistent direct effects in grades 3–4–5 and complementary transfer effects in grades 6–7 on both ITBS Science (+1.08 Grade Equivalent Units [GE]) and ITBS Reading (+.57 GE). Discussed are implications of the findings and related research for changing grade K-5 curriculum policy to allocate increased instructional time for integrated science instruction.  相似文献

This article examines college student disengagement from sports, presents a multidimensional concept of athletic identity, and introduces a new measure intended to assist college counselors in their work with disengaged athletes. The Multidimensional Athletic Identity and Engagement Scale (MAIES) is introduced (Cronbach alpha .98, with subscale alphas between .78 and .96), and the results of exploratory and confirmatory factor analyses and convergent and divergent validity with 250 college student participants are presented. Using case examples, the authors discuss how counselors may use the MAIES in their work with students. Limitations of the study and suggestions for future research are discussed.  相似文献

Bridging schools and communities has been a goal, if not hurdle, for reformers who aim to improve the education of low-income and underrepresented students from the bottom-up. Strategies to create these connections are often characterized as ‘brokerage’, where individuals or organizations bridge two or more social worlds. This paper details the design and implementation of educational technologies that support the brokering of school–community connections using a ‘culturally responsive computing’ (CRC) framework. Culturally responsive education is often limited to content and learning styles, which misses the opportunities it creates for a brokerage process that also connects to education-based social movements for economic access in underrepresented communities. This paper provides empirical support for the claim that the CRC framework is well suited for both purposes. It allows schools and communities to build assets together, translating the knowledge and skills of underrepresented communities into math and computing education, while illuminating the ways in which technologies can motivate education-based social movement building.  相似文献
