幼教工作者对特殊幼儿融合教育问题的态度和意见的调查研究

为了解普通幼儿园工作者对特殊幼儿融合教育问题的态度和意见,本文对174名教师和保育员进行问卷调查,主要发现:(1)幼教工作者对特殊幼儿有一定的了解,但不够深入;(2)幼教工作者以及普通幼儿家长在保障师资、设备以及教育方式的情况下,更乐意接受特殊幼儿进入普通幼儿园;(3)幼教工作者认为学前阶段实施特殊教育最需解决的问题依次为师资问题、设备问题、家长观念、教师观念、经费问题以及专设督导机构问题。     

论蔡锷的反帝爱国思想

清末民初,蔡锷以极大的热情关注着国家和民族的命运,从当时的历史背景出发,无情揭露和严正批判帝国主义列强对中国的侵略行为,并积极探寻反帝救国的途径,提出了一系列反帝爱国的观点和主张,对于当时中国人民反对帝国主义侵略、争取国家的独立和民族的解放运动产生了积极的影响。     

一篇兰雪写冰心--略论张玉娘和她的诗歌创作

宋末元初浙江籍女作家张玉娘有着祝英台般为情而亡的凄美经历,好的遗稿《兰雪集》直追《漱玉集》和《断肠集》。好的诗人除了拥有大量的爱情伤口外,还有反映时代背景和个人识见的边塞诗,咏史诗,题画诗等,显现出多样的风格和鲜明的创造力。通过以张玉娘作品的分析,可见其坎珂的经历,亦可感受到那个时的女性固有的悲哀。

The effectiveness of learning analytics for identifying at-risk students in higher education

Abstract

In this article we investigate the effectiveness of learning analytics for identifying at-risk students in higher education institutions using data output from an in-situ learning analytics platform. Amongst other things, the platform generates ‘no-engagement’ alerts if students have not engaged with any of the data sources measured for 14 consecutive days. We tested the relationship between these alerts and student outcomes for two cohorts of first-year undergraduate students. We also compared the efficiency of using these alerts to identify students at risk of poorer outcomes with the efficiency of using demographic data, using widening participation status as a case study example. The no-engagement alerts were found to be more efficient at spotting students not progressing and not attaining than demographic data. In order to investigate the efficacy of learning analytics for addressing differential student outcomes for disadvantaged groups, the team also analysed the likelihood of students with widening participation status generating alerts compared with their non-widening participation counterparts. The odds of students with widening participation status generating an alert were on average 43% higher, demonstrating the potential of such a system to preferentially target support at disadvantaged groups without needing to target directly based on immutable factors such as their socio-economic background.     

Nonlinear Growth Mixture Models With Fractional Polynomials: An Illustration With Early Childhood Mathematics Ability

Applications of growth mixture modeling have become widespread in the fields of medicine, public health, and the social sciences for modeling linear and nonlinear patterns of change in longitudinal data with presumed heterogeneity with respect to latent group membership. However, in contrast to linear approaches, there has been relatively less focus on methods for modeling nonlinear change. We introduce a nonlinear mixture modeling approach for estimating change trajectories that rely on the use of fractional polynomials within a growth mixture modeling framework. Fractional polynomials allow for more parsimonious and flexible models in comparison to conventional polynomial models. The procedures are illustrated through the use of math ability scores obtained from 499 children over a period of 3 years, with 4 measurement occasions. Techniques for identifying the best empirically derived growth mixture model solution are also described and illustrated by way of substantive example and a simulation.     

Parental guidance of young children’s mathematics and scientific inquiry in games,cooking, and nature activities

ABSTRACT

This study investigated the influence of guidance instruction and type of activity on parental guidance of young children’s mathematics and scientific inquiry during cooking, games, and nature activities at home. Thirty families participated with their preschool-aged child; half were randomly assigned to an inquiry guidance instruction group and encouraged to support children’s reasoning with open-ended prompts and questions. Families participated in activities for one month, some of which they audio-recorded. Families engaged in processes of comparing, predicting, evaluating and concluding more often after inquiry guidance instruction, and incorporated inquiry processes into all activity types. Mathematics was most frequently observed in games and cooking. The results suggest that parents can use inquiry guidance to support preschoolers’ mathematics and scientific inquiry in a variety of activities performed at home. As children engage in inquiry-based learning during co-constructed activities with parents, they develop conceptual understanding of mathematics and scientific inquiry in a positive social context.     

The acceptance of computer technology by teachers in early childhood education

This study investigated kindergarten teachers’ decision-making process regarding the acceptance of computer technology. We incorporated the Technology Acceptance Model framework, in addition to computer self-efficacy, subjective norm, and personal innovativeness in education technology as external variables. The data were obtained from 160 kindergarten teachers, from public kindergartens in Daejeon, South Korea. According to the results, subjective norm had the strongest effect on computer acceptance. In addition, perceived usefulness and computer self-efficacy had a direct effect on computer technology acceptance. On the other hand, perceived ease of use and personal innovativeness in education technology had an indirect effect on computer technology acceptance. The measures accounted for approximately 32% of the variance of intentions to use computers in kindergartens.
