Well-developed programming (technical) skills are very important for software engineers, information systems engineers and programmers in general. However, they must also possess relevant personal skills (soft skills) to be successful at the workplace (eg, collaboration, solving real-world problems and communication). The latter, however, are rarely assessed and acknowledged in regular software engineering courses. This paper describes the results of a small case study involving an extracurricular Java programming course in which, in addition to knowledge and skills in relevant technologies, students' soft skills were also assessed. As part of the assessment, students have been awarded Open Badges. The study was exploratory in nature, aimed at examining Open Badges as a motivational mechanism, students' engagement in attaining soft skills and students' perception of soft skills and Open Badges. The results suggest that Open Badges may not be so effective in motivating students to complete the assignments nor attend the course, although students' perception of Open Badges is generally positive. Soft skills were generally perceived as important as hard skills. Students' engagement in attaining soft skills could be affected by assignment announcement time and its level of difficulty. 相似文献

Research Findings: Drawing from a diverse community sample of 89 children, ages 4–6, their primary caregivers and teachers, this study examined the interplay of child emotional behavior problems, parent emotion socialization practices, and gender in predicting teacher-child closeness. Teachers reported on perceptions of closeness with children. Parents and teachers reported on children’s emotional behavior problems, as indexed by overanxious behavior, overt, and relational aggression. Regression models revealed that higher relational aggression related to closer teacher-child relationships for all children of parents who employed minimization as an emotion socialization practice. Similarly, higher overt aggression related to closer teacher-child relationships for girls who experienced parent minimization. An analogous pattern of results emerged, such that lower parent emotional support buffered girls against the negative effects of higher relational aggression on teacher-child closeness, whereas higher parent emotional support related to lower levels of closeness for these girls. These findings contradict prior research linking supportive emotion socialization practices (e.g., empathy, comforting) to socioemotional competence and unsupportive practices (e.g., minimization, punishment) to poor school adjustment. Practice or Policy: Findings have implications for improving children’s classroom experience by identifying parent emotion socialization and gender as contexts for understanding child emotional behavior problems in relation to teacher-child closeness. 相似文献

The protection of human health and the preservation of the environment are topics that form an integral part of the primary school curriculum in Serbia. However, research studies have shown that students do not have enough knowledge to contribute to the development of a healthy lifestyle and environmental awareness. The latest changes in school policy and curricula confirm that the relevance of environmental education has been recognized, but changes in school practice are yet to come. This article discusses the challenges encountered in the implementation of the intended curriculum and offers suggestions for changes to the curriculum, pedagogy, and teacher training in order to enhance environmental education. 相似文献

The ever increasing presence of online social networks in users’ daily lives has led to the interplay between users’ online and offline activities. There have already been several works that have studied the impact of users’ online activities on their offline behavior, e.g., the impact of interaction with friends on an exercise social network on the number of daily steps. In this paper, we consider the inverse to what has already been studied and report on our extensive study that explores the potential causal effects of users’ offline activities on their online social behavior. The objective of our work is to understand whether the activities that users are involved with in their real daily life, which place them within or away from social situations, have any direct causal impact on their behavior in online social networks. Our work is motivated by the theory of normative social influence, which argues that individuals may show behaviors or express opinions that conform to those of the community for the sake of being accepted or from fear of rejection or isolation. We have collected data from two online social networks, namely Twitter and Foursquare, and systematically aligned user content on both social networks. On this basis, we have performed a natural experiment that took the form of an interrupted time series with a comparison group design to study whether users’ socially situated offline activities exhibited through their Foursquare check-ins impact their online behavior captured through the content they share on Twitter. Our main findings can be summarised as follows (1) a change in users’ offline behavior that affects the level of users’ exposure to social situations, e.g., starting to go to the gym or discontinuing frequenting bars, can have a causal impact on users’ online topical interests and sentiment; and (2) the causal relations between users’ socially situated offline activities and their online social behavior can be used to build effective predictive models of users’ online topical interests and sentiments. 相似文献

Introduction
Acute kidney injury (AKI) is common in neonatal intensive care units (NICU). In recent years, every effort is made for early detection of AKI. Our hypothesis was that serum neutrophil gelatinase-associated lipocalin (sNGAL) may be a reliable screening test for early diagnosis of AKI in premature neonates after perinatal asphyxia. Therefore, our aim was to assess the diagnostic accuracy of sNGAL for AKI in premature asphyxiated neonates.Materials and methods
AKI was defined in the third day of life (DOL 3) as a serum creatinine (sCr) increase ≥ 26.5 μmol/L from baseline (the lowest previous sCr). According to the increase of sCr, AKI patients were divided in AKIN1 (sCr increase up to 1.9 baseline) and AKIN2 (sCr increase from 2.0 to 2.9 baseline). sNGAL levels were measured on DOL 1, 3 and 7.Results
AKI was diagnosed in 73 (0.676) of 108 enrolled premature asphyxiated neonates. Sixty one patients (0.836) were classified in AKIN1 and 12 patients (0.164) in AKIN2. sNGAL reached the maximal concentrations on DOL 1 within 4 hours after admission to NICU, being higher in AKI compared with no-AKI group (160.8 ± 113.1 vs. 87.1 ± 81.6; P < 0.001) as well as in AKIN2 compared with AKIN1 group (222.8 ± 112.9 vs. 147.8 ± 109.9; P < 0.001). The best areas under the receiver operating characteristic curves (AUC) for prediction of AKI were 0.72 [95% (0.62-0.80) P < 0.001] on DOL1 at 2h and 0.72 [95% (0.63-0.80) P < 0.001] at 4th hour after admission respectively. The corresponding sNGAL cutoff concentrations were 84.87 ng/mL (sensitivity 69.0% and specificity 71.9%) and 89.43 ng/mL (sensitivity 65.7% and specificity 74.3%).Conclusions
In premature asphyxiated neonates sNGAL measured within the first 4 hours of DOL 1 is predictive of the occurrence and severity of AKI. Therefore, plasma levels of NGAL may be used for early diagnosis of AKI in these patients.Key words: serum neutrophil gelatinase-associated lipocalin, acute kidney injury, premature neonates, biomarker 相似文献7.

This paper presents the concept and the implementation of the Content and/or Knowledge Provision (CKP) service. The service is developed as a part of research within Intelligent Learning Extended Organization, an 7th Framework Program for R&D project in the area of technology-enhanced learning. The project aimed at enhancing cross-organizational Learning and Knowledge Building (LKB) practices at workplaces, leading to continuous growth of organization’s intellectual capital. By using the CKP service, employees can upload different kinds of knowledge assets into a knowledge repository, annotate them and (re-)discover relevant ones by performing semantic search over the knowledge repository. Hence, the service effectively serves as a content and knowledge-sharing facility and semantic search engine within a learning organization. Furthermore, CKP enables collaborative manipulation and annotation of knowledge assets in the repository, thus supporting all three components of intellectual capital. 相似文献

Numerous educational reforms have been initiated in Serbia since 2000. The aim of this study was to examine education policymaking in Serbia in order to provide policymakers and stakeholders with recommendations on how to minimize pitfalls and increase success of future educational endeavors. In the study, we utilized the education policy cycle heuristic to analyze formation, implementation, and evaluation of three major education policies in Serbia: in-service training of teachers (INSET), school development planning (SDP), and inclusive education (IE). Examining three reforms simultaneously enabled us to identify major characteristics of Serbian policymaking, regardless of the reform content. We also relied on educational change literature, so that we could assess complex contexts of reforms. Finally, considering the importance of school staff during implementation, we examined education policymaking in Serbia through the eyes of over 1,800 teachers, counselors, and principals. The results point out to dissatisfaction of school staff with all aspects of the policymaking in Serbia and with the social and education context. Reforms appear to be undertaken in a similar pattern across different reforms. The findings imply that a thorough examination of both the policymaking in Serbia and communication, organization, and administration within the education system itself is in order. 相似文献

ABSTRACTResearch Findings: Using data from a short-term longitudinal study of 343 third-, fourth-, and fifth-grade students, we investigated visual-motor integration (VMI) skills as a predictor of direct assessments of executive functions (EFs) and academic achievement. This is the first study to investigate relations among these three constructs in late elementary school. VMI predicted change in EFs from fall to spring. EFs and VMI were independently associated with math and English/language arts standardized test scores. When controlling for earlier achievement test scores, EFs—but not VMI—remained a significant predictor of later academic achievement. Results indicate that VMI may help support the continued development of EFs in late elementary school, but EFs appear to be comparatively more important as a direct predictor of continued academic development during this age period. Practice or Policy: VMI is a complex ability that combines fine motor coordination (an aspect of school readiness) and visual-spatial reasoning skills. VMI has been identified as an influential predictor of early academic development, but it has been neglected in middle childhood studies. Our results suggest that VMI remains important through the end of elementary school for the continued development of children’s EFs and therefore merits more attention from researchers and educators. 相似文献

ABSTRACTThe study aimed to investigate variations in addition and subtraction fluency by observing grade three students in Norway (n = 253, Mage = 8.38 y.) and Finland (n = 209, Mage = 9.35 y.) while controlling for their age and non-verbal reasoning. Gender differences were also examined. The focus of the study was on the performance of the low-achieving (LA) students in comparison to the typically achieving (TA) group, not neglecting differences in how early educational support was organised across the two countries. Two-minute speed tests in both addition and subtraction within the 1–20 number range were used to assess fluency. The Finnish students outperformed students in the Norwegian sample both in addition and subtraction fluency. There were more Norwegian students in the LA group (i.e. performance at or below the 25th percentile) in both addition (37.9% vs. 20.1%) and subtraction (39.1% vs. 15.8%). In comparison to the TA students, the LA students made more errors and skipped over more arithmetic tasks in an attempt to solve them. Observed differences are discussed in relation to both country characteristics concerning early mathematics education and early educational support. 相似文献
