基于数据共享的标准系统的有效性分析——以煤炭企业为例     

谭章禄  袁慧  马营营 《科技管理研究》2019,39(4)

信息化标准是解决系统集成、数据共享的基本途径。本文以煤炭企业为切入点探讨信息化标准的有效性。基于煤企在引入一系列信息系统后产生的对信息化标准的客观需求，本文将信息化标准看作一个系统，从煤企信息系统建设的5个阶段以及信息化标准系统3个阶段出发，分析了有效的煤企信息化标准应该同时具有适应性A（adaptability）、实用性F（functionality）、可实现性R（realizability）、参与性J（joint）、科学性S（scientificity）、前瞻性P（prospective）等特性，在此基础上提出了煤企信息化标准系统有效性的影响因素并给出了因素关系图和关系链图。最后，构建了标准有效性的计算公式。  相似文献   

Searching for the impact of teacher behavior on promoting students’ cognitive and metacognitive skills     

《Studies in Educational Evaluation》2020

This study investigates the impact of teaching factors on students’ cognitive and metacognitive achievement in mathematics. Written tests and the “Metacognitive Skills and Knowledge Assessment” tool were administered to grade 4 and 5 students (n = 924) at the beginning and end of the school year 2013-2014. A student questionnaire was used for measuring teaching factors. Multilevel SEM analyses revealed a reciprocal relationship between students’ cognitive and metacognitive skills. All teaching factors of the dynamic model of educational effectiveness were found to be associated with mathematics achievement but only four factors (modeling, assessment, questioning, and dealing with misbehavior) were associated with two aspects of metacognition (i.e. prediction and evaluation). Implications of findings are drawn.  相似文献   

新时代高等职业院校思想政治教育有效性实现方法探究     

皮睿 《科教导刊》2021,(3):78-79

新时代背景下,高职院校扩招增加了更多的生源,而对于学生管理工作的要求就更高.对于高职院校的人才培养来说,我们要做的不单单是学生的技能,更需要从根源上着手,让学生自发学习,有效学习,而这需要建立在有效的思想政治教育的基础之上,为了能达到此效果,就需要对当今的思想政治教育模式进行分析研究,针对其中的不足和学生的特点进行研究,以此得出的实现方法才是科学的、有效的.基于此本文进行研究分析,最终得出思想政治有效教育模式的开展策略.  相似文献   

语用视角下英语教学话语有效性建构路径     

《信阳师范学院学报(哲学社会科学版)》2018,(6):117-120

英语教学话语有效性的实现是课堂教学成功的根本保证,从普遍语用学的有效性要求和认知语用学的可供性提取理论来看,英语教学话语有效性建构必须满足以下两个条件:一是提高认知式语言使用中的真实性、互动式语言使用中的恰当性、表现式语言使用中的真诚性;二是重视教学话语的主体间性,做好教学话语的可供性提取。  相似文献   

Administrative and structural changes in student evaluations of teaching and their effects on overall instructor scores     

Nina Zipser 《Assessment & Evaluation in Higher Education》2018,43(6):995-1008

Using nine years of student evaluation of teaching (SET) data from a large US research university, we examine whether changes to the SET instrument have a substantial impact on overall instructor scores. Our study exploits four distinct natural experiments that arose when the SET instrument was changed. To maximise power, we compare the same course/instructor before and after each of the four changes occurred. We find that switching from in-class, paper course evaluations to online evaluations generates an average change of ?0.14 points on a five-point scale, or 0.25 standard deviations (SDs) in the overall instructor ratings. Changing labelling of the scale and the wording of the overall instructor question generates another decrease in the average rating: ?0.15 of a point (0.27 SDs). In contrast, extending the evaluation period to include the final examination and offering an incentive (early grade release) for completing the evaluations do not have a statistically significant effect on the overall instructor rating. The cumulative impact of these individual changes is ?0.29 points (0.52 SDs). This large decrease shows that SET scores are not comparable over time when instruments change. Therefore, administrators should measure and account for such changes when using historical benchmarks for evaluative purposes (e.g. appointments and compensation).  相似文献   

Interactive groups for immigrant students: a factor for success in the path of immigrant students     

Diana Valero  Gisella Redondo-Sama  Carmen Elboj 《International Journal of Inclusive Education》2018,22(7):787-802

Student’s learning is the result of a large number of interactions in all areas. Consequently, with an increasing number of intercultural students, we need to bring to the classrooms successful educational actions that enhance interactions and that have an impact on improving education. Based on the CONEXITO project, this article shows how interactive groups (IGs) have contributed to increase not only the educational success of native students but also the success of immigrant students in different schools of Spain, for which IGs have particular educational outcomes. The communicative qualitative data presents evidence that, especially focusing on them, IGs increase instrumental learning and facilitate the bonds of solidarity and mutual help.  相似文献   

Tackling inequality? Teacher effects and the socioeconomic gap in educational achievement. Evidence from Chile     

Rodrigo Torres 《School Effectiveness & School Improvement》2018,29(3):383-417

Although teacher quality is usually signalled to be the most relevant school-level factor impacting students’ learning, little is known about the relevance of teacher effects explaining educational inequality. By using a value-added model for a cohort of 10th graders, in this work we examine the socioeconomic gap in teacher effects across Chilean secondary schools, and its importance in explaining socioeconomic inequality in students’ achievement in math and language. We found an important proportion of highly effective teachers in low-socioeconomic-status (SES) schools, but also much bigger variation in teacher effects across those schools. Variability in teacher effects decreases when moving towards higher SES schools, where there is also a smaller proportion of low-performing teachers. All in all, teacher effects have a levelling impact for students in low-SES schools when compared to those in middle SES schools, but no significant impact when compared to students in high-SES schools.  相似文献   

我国单项体育协会改革的软法之治

Facilitating flexible learning by replacing classroom time with an online learning environment: A systematic review of blended learning in higher education     

《Educational Research Review》2021

Higher education institutions are trying to provide more flexibility and individualization, which is mainly realized through the use of new technologies and implemented in online or blended learning designs. This systematic review aims to investigate the impact of replacing classroom time with an online learning environment. The meta-analysis (k = 21 effect sizes) applied strict inclusion criteria concerning research design, measurement of learning outcomes and implementation of blended learning. The estimated effect size (Hedge's g) was positive, although not significantly different from zero and the confidence interval [-0.13, 0.25], suggesting that overall differences between blended and conventional classroom learning are small, and, at best, very small negative or moderate positive effects are plausible. This means that despite a reduction in classroom time between 30 and 79 per cent, equivalent learning outcomes were found. Consequently, blended learning with reduced classroom time is not systematically more or less effective than conventional classroom learning.  相似文献   

How can we evaluate the effectiveness of grammar schools in England? A regression discontinuity approach     

Binwei Lu 《British Educational Research Journal》2020,46(2):339-363

Previous research evaluating grammar school effectiveness has generally relied on snapshot or longitudinal regression models to deal with pre-existing differences between grammar school pupils and those in non-selective schools. These passive designs are based on correlations, and cannot demonstrate clear positive causal relationships between grammar school attendance and subsequent attainment. After accounting for the variables available for the analysis, pupils in different schools might still have distinct and unmeasured characteristics which threaten the validity of any conclusions drawn. Given that a randomised trial is not feasible under current conditions, this study addresses the limitations of previous research, using a regression discontinuity design (RDD) approach. This is the first use of RDD to attempt to make a robust causal inference about the effectiveness of grammar schools in one local authority in England. However, the authority, the Department for Education and the schools would not provide the individual data on pupils’ 11+ entry test scores, and the scores obtained could not be uniquely matched to Key Stage 4 outcomes. While the model presented suggests that there is an advantage to grammar school attendance, the incomplete data means that the study is more a feasibility trial of this strong design than any kind of definitive test intended to settle the debate on grammar school effectiveness. Conducting this design with national data on grammar school selection would create the most powerful evidence so far. To promote an effective and equitable education system for generations to come, those advocating the expansion of grammar schools should make the responsible decision to disclose all grammar school selection data for the purposes of research.  相似文献
