Whether and to what extent kindergarten children's executive functions (EF) constitute promising targets of early intervention is currently unclear. This study examined whether kindergarten children's EF predicted their second-grade academic achievement and behavior. This was done using (a) a longitudinal and nationally representative sample (N = 8,920, M_age = 97.6 months), (b) multiple measures of EF, academic achievement, and behavior, and (c) extensive statistical control including for domain-specific and domain-general lagged dependent variables. All three measures of EF—working memory, cognitive flexibility, and inhibitory control—positively and significantly predicted reading, mathematics, and science achievement. In addition, inhibitory control negatively predicted both externalizing and internalizing problem behaviors. Children's EF constitute promising targets of experimentally evaluated interventions for increasing academic and behavioral functioning.  相似文献

Cloud e-learning service strategies for improving e-learning innovation performance in a fuzzy environment by using a new hybrid fuzzy multiple attribute decision-making model     

Chiu Hung Su  Gwo-Hshiung Tzeng  Shu-Kung Hu 《Interactive Learning Environments》2016,24(8):1812-1835

The purpose of this study was to address this problem by applying a new hybrid fuzzy multiple criteria decision-making model including (a) using the fuzzy decision-making trial and evaluation laboratory (DEMATEL) technique to construct the fuzzy scope influential network relationship map (FSINRM) and determine the fuzzy influential weights of the fuzzy DEMATEL-based analytic network process (DANP) as well as (b) the modified VIKOR method combining fuzzy influential weights of fuzzy DANP to integrate each criterion of fuzzy performance gaps into dimensions and, overall, to examine the interdependent and feedback problems among various dimensions/criteria of cloud e-learning services for creating the excellent improvement plan based on the FSINRM to implement the strategic orientations. An empirical case of the network communication service industry was used as an example to show the proposed methods and ultimately present the most effective improvement plan for decision-makers to achieve the aspiration level.  相似文献

Teaching new product development in universities: an action learning approach     

Kit Fai Pun  Richard C. M. Yam  Hongyi Sun 《European Journal of Engineering Education》2003,28(3):339-352

This paper reviews the concepts of new product development (NPD) and discusses the change of traditional lectures into an action learning approach of teaching NPD in universities. It explains the design and delivery of an action learning NPD course, drawing upon the experience from an engineering department at the University of the West Indies, Trinidad. The course stresses student participation, teamwork, group decision-making and learning process evaluation. Despite classroom lectures and tutorials, it incorporates group learning activities and a competitive management workshop into a NPD curriculum for undergraduates. The workshop has been implemented with encouraging results in student learning and development.  相似文献   

Theory to reality: a few issues in implementing problem-based learning   总被引：1，自引：0，他引：1  

Woei Hung 《Educational technology research and development : ETR & D》2011,59(4):529-552

The success of an intervention depends not only upon its theoretical soundness, but also on proper implementation that reflects the guidelines derived from its theoretical conception. Debates surrounding the effectiveness of problem-based learning (PBL) have focused on its theoretical conception and students’ learning outcomes, but implementation is seemingly absent from the picture. This paper attempts to describe what research evidence is needed to fill in this missing information and provide a clearer picture of PBL. The author examines current PBL implementation practices and identifies potentially confounding variables that may play a role in inconsistent or conflicting research results in PBL. For example, various models of PBL have been developed and implemented to afford the specific instructional needs of the institution or learner population. These PBL models are in fact quite different in terms of the nature of problem solving and the degrees of self-directed learning, which theoretically, should result in different types of learning outcomes. Without distinguishing the models used, the results of comparative PBL research could have been confounded. Furthermore, human factors are another set of confounding variables that could influence the students’ learning processes and consequently affect PBL implementations and research results. To remedy these problems and reach PBL’s full potential, as well as obtain a more accurate picture of PBL as an instructional method and its effects on students’ learning, some fundamental changes are needed.  相似文献

In the northern part of South China Sea, including Tonkin Gulf, Hainan lsland, Leizhon Peninsula and some basin of Guangdong  Province,  Paleogene  deposits  are composed of three formations: the Weizhon, the Liushagang and the Changliu forma- tions arranged in descending order.  The paper on the palynoflora of the Weizhon Formation (early and middle Oligocene) is in press[2].  This paper deals only with the palynoflora of the Liushagang Formation, with may be divided into four main stages:       The first stage is represented by Monocolpollenites tranquillus and Crassoretitri- letes sp., assigned to early Eocene The second stage is characterized by Salixipollenites, Momipites triletipollenites and Operculumpollis.  Its age is middle Eocene.  The third stage is dominated by some species of Quercoidites  and  Ulmipollenites  and  also characterized by the presence of Platycaryapollenites  and Prominangularia  dogying- ensis, This sporo-pollen assemblage suggests a late Eocene in age.  The fouth stage is marked by profusion of some alga of brockish water, such as Rugasphera corrugia, Granodiscus gronulatus and some pollen types  of  Liquidambarpollenites   minutus, Multiporopollenites puctatus and Tricolporopollenites minutus.  The age of the last stage is assigned to early oliocene.       In generaly, the palynoflora of the Liushagang Formation is quite different from that of the Weizhou Formation.  The main types of spores and pollen are common with those found in Europe and North America of the same age, while the Weizhou Formation has many elements common both in this region and Borneo.       During Eocene and early Oligocene this area was  of continental  phase with brackish basins. At the beginning the climate was rather moist and hot, but then itbecame moist and warmtemperate.  相似文献
