Pathways from parental stimulation of children’s curiosity to high school science course accomplishments and science career interest and skill

Curiosity is fundamental to scientific inquiry and pursuance. Parents are important in encouraging children’s involvement in science. This longitudinal study examined pathways from parental stimulation of children’s curiosity per se to their science acquisition (SA). A latent variable of SA was indicated by the inter-related variables of high school science course accomplishments, career interest, and skill. A conceptual model investigated parental stimulation of children’s curiosity as related to SA via science intrinsic motivation and science achievement. The Fullerton Longitudinal Study provided data spanning school entry through high school (N?=?118). Parental stimulation of curiosity at age 8 years comprised exposing children to new experiences, promoting curiosity, encouraging asking questions, and taking children to a museum. Intrinsic motivation was measured at ages 9, 10, and 13 years, and achievement at ages 9, 10, and 11 years. Structural equation modelling was used for analyses. Controlling for socio-economic status, parental stimulation of curiosity bore positive and significant relations to science intrinsic motivation and achievement, which in turn related to SA. Gender neither related to stimulation of curiosity nor contributed to the model. Findings highlight the importance of parental stimulation of children’s curiosity in facilitating trajectories into science, and relevance to science education is discussed.

公共图书馆免费开放视野下的古籍读者服务

在公共图书馆免费开放的背景下,古籍读者服务工作也相应发生了变化。在古籍阅览的规定方面减少了手续,降低了收费标准,但相应的古籍服务仍不应该完全免费;针对古籍读者群体专业性、目的性强、地域广泛性等特点,公共图书馆应在古籍原件保护、图书馆员业务水平、古籍数字化、地方文献开发和古籍阅览环境等方面采取措施,做好古籍读者服务工作。

An Approach for Personalized Recommendation via Hypergraph Projection and Random Walk

以大众分类(folksonomy)为基础的社会化网络中,通常用标签对资源特征和用户喜好进行描述,本文将标签语义引入传统的推荐系统,从用户的标注行为入手,提出一种基于超图投影的推荐方法,该方法利用投影图中节点的连边权重进行节点相似性度量,使待推荐对象在投影图上随机游走,根据待推荐对象在节点上停留概率获得推荐,实验结果表明标签的引入提高了推荐质量,算法在精确性和多样性上均有很好的改进.     

Identification of dysfunctional cooperative learning teams and troubled individuals

In cooperative learning, students work together as a team to maximize the academic success of all the team members. The failure of even a single member can compromise the success of the entire team. Thus, to evaluate the functioning of the team reliably, it is necessary to consider both the performance of the individual team members and the interactions among them. In this study, a method was developed for identifying dysfunctional teams and troubled individuals by examining the correlation between the team scores obtained in sequential tests and the correlation between the scores obtained by the different team members. The effectiveness of the proposed method was evaluated via field experiments. Forty‐eight students were randomly assigned to cooperative learning teams and their learning performance assessed by four‐unit tests. The results indicated that the proposed method can identify the most troubled individuals in a team even when the team performance/grouping information is not taken explicitly into account. Furthermore, when the team information is considered, the method can identify both the dysfunctional teams and the troubled individuals within the teams. Therefore, the proposed method provides a useful basis for the development of computer‐assisted solutions for assessing the performance of cooperative learning teams.
